Essence of life develops promotion application of the technology

All sorts of metal ability of 5 ～ 16mm the board shape part with qualitative, complex form. As a result of its dimension and form precision demand is high, ask along makings thick direction especially bright and clean, flat. Groovy conventional treatment method is offer semifinished product by punch, with car, mill, dig, grind wait for cutting treatment to amount to want its technology requirement, not only technological process long, working procedure is much, bad news uses worker worker (stage) when much, manufacturing efficiency is low, and spare parts interchangeability is bad, labor strength is great, cost is high, cannot get used to mass-produced need. Carry out a proof, in 3mm of ＞ of makings thick T in thick board with T ＞ 4.

75mm is thick board in production of spare parts big batch, promotion application essence is replaced to the technology have cut treatment, can obtain very good economic benefits not only, still can put an end to what happen from time to tome in common punch production at present to press a hand to break at the same time show person harms an accident, the pollution of pare punch noise to the environment, get satisfactory professional safety and environmental protection benefit. The nicety in using contemporary punch field is strong cut hi-tech into parts, sufficient also body is revealed " it is with the person this, insist to be able to develop continuously " scientific progress view. The graph is shown 1 times for the choice that Swiss FeintoolAGLyss/schweiz essence offers for the user to the company is strong. These board shape spare partses are finished hard with other treatment method. Even if constitutes cutting treatment with each type of work, not only efficiency card of one cannot say for sure of low, quality, and cost is very high. The graph shows the steel plate that great majority is different name 1 times to pledge, 80% above are the car rushs with essence of life. The analysis pursues 1 show the choice that give to rush can see its are as follows characteristic: 1) form is complex, dimension and form precision is tall, ～ of 3mm of ＞ of most makings thick T 12.

5mm, in be thick board with thick board choice is strong, strong tangent plane is flat, bright and clean, quality can be rivalled with cutting treatment. 2) choice is strong clear-cut, collapse part is small, limit of a few opening is apart from be apart from with Kong Jian (the wall is large) ≤ T has press protruding, heavy aperture, blind the figuration choice such as flange of Kong Ji hub is strong, especially the choice of gear of appearance high accuracy such as the involute with very small modulus, cycloidal, triangle, rectangular, echelon is strong, make hard with other treatment craft. 3) it is big batch production and the part of mechanical and electrical products that reach moderate economy scale of production, include: The product essence such as carring capacity car, car, autocycle gets stuck to rush in, all by raw material one model develops a finished product, no longer cutting treatment. 4) because the strong tangent plane with strong choice is cold make sclerotic effect, its surface hardness, intensity rises considerably, be able to bear or endure attrition function and be able to bear or endure the improvement that await a gender, use as the choice such as the gear tooth profile of athletic face, attrition face, axle sleeve is strong, its life can rise because of this. The nicety that the development application plate of energy strong technology expects develops the result that cutting into parts is theory of success application TheodorKarman. This academic core is: The plasticity when solid issues more one-way than be in press press to the circumstance of press press in how is good, be out of shape position is better, be out of shape more easily. Rush in board makings nicety when cutting into parts, use essence of life to develop model different structure, separate division is cut in the shears of board makings, 3 to apply pressure form establish body to control stress state, undertake to material pure cut depart, implementation nicety is strong cut into parts. German F.

Schiess was invented theoretically according to this 1921 puissant the essence that approach a limit develops engineering technology (abbreviation FB choice is strong) , got German patent on March 9, 1923. In afore-mentioned FB essence strong engineering technology popularizes around, still have other a variety of essence develop development success in different country to the method, obtain patent, some is promotional still at production. Up to now, still a few simple and easy essence develop technology, develop technical complement as FB essence, in a few appearance simple, only local need essence strong, size is small and crop is not big and in the factory of strong without special spirit equipment, promotion application, can obtain good technical economic benefits likewise, these essence are as follows to the technology: (1) essence of life develops common compressor technical A, rebuild -- with special rebuild also say to repair edge model to expect to falling the strong tangent plane with punching semifinished product undertakes the edge is machined repairing in order to get flat, bright and clean the strong section that reachs high accuracy, include: The predestined relationship rebuilds outside, inside aperture rebuilds, fold makings rebuild, vibration rebuilds etc. B, bright and clean strong cut into parts -- use small space or lose point of clearance round horn to wait for the special die that has special structure, strong to the mild steel of tall plasticity and nonferrous metal cut into parts undertake bright and clean strong cut into parts, the high accuracy that gets bright and clean level develops tangent plane. Commonly used bright and clean strong cut craft into parts to have: Point of small clearance round horn is bright and clean strong cut into parts, negative gap is bright and clean strong cut into parts, punching of essence of step type punch, synchronism cuts crowded fine punching of essence of strong, extruding and rush without burr cut into parts etc. (2) spirit of A of strong technology of essence of life of special spirit strong opportunity, puissant pressing plate -- those who use different structure is puissant press makings board to undertake approaching a limit, instead top and rush to the nicety that cut into parts cut into parts (FB) , include: The essence that already popularized those who be used at production to encircle pressing plate of puissant the energy strong technology that approachs a limit and the pressing plate of band saw flute profile that use lesser, cone-shaped pressing plate, protruding stage form with V tine develops a method... etc. B, right rush to sunken model essence -- use planar cutting principle, the didymous punch that uses fluctuation correspondence and sunken model are divided by formulary rate second strong cut, it is Japanese is in Japan at was being invented 1968 promotional already the essence at production develops a technology. Home also has use but did not popularize. C, answer move and choice of move back and forth is strong -- did not popularize application. In the of all kinds Electromechanical of the spot and production of stamping workpiece of home appliance product, what real favourable or unfavourable turns in life arrives to need and can undertake integral essence rushs is strong cut into parts kind of number is limited. And have comparative to rush partly need local essence to rush only, want essence of life to develop its only especially group of aperture, group the one fraction of groovy aperture, application is common compressor essence develops a technology more economy; Local to needing only choice is strong obtain form of high accuracy aperture and pitch, without burr and strong tangent plane is bright and clean of level off inside of form or partial appearance strong cut into parts, can have clean develops light cut into parts achieve a requirement. The engineering technology level with strong choice popularizes applied essence for a long time to develop practice specification of the technology, choice is strong the level that quality already reached cutting to add workpiece. In mass-produced useful essence of life rushs to the technology make ＞ of makings thick T 0.

All sorts of board shape spare partses of 5 ～ 16mm, especially the appearance is like gear, ratchet, cam complexly piece and stop a vehicle by applying the brakes of the sector gear with very difficult also treatment of common cutting machine tool, aircraft piece, diesel engine face plate, not only low consumption of can high grade high yield, and rate of automation of strong opportunity of essence of life is high, the strong engine of new-style CNC essence that produces in last few years, the function is all ready, majority is 3 move O of complete hydraulic pressure frame to shut type construction, essence of life develops a process to be run automatically in airtight space completely, the operation is very safe, the 85dB that working noise does not exceed a standard to set (A) . Essence of life develops a technology (FB) the hi-tech that is punch domain, equipment and mould have quite the hi-tech content of abundant, it is foreground values the new technology that is worth to be popularized energetically. With essence of life strong technology promotes essence of punch technology level strong technology is what by a variety of foundation engineering technology combination makes one is giant and complex system project, include: The metal treats design of die of raw material treatment and refine technology, its pre-treatment technology, essence to make with repair a technology, essence of life grinds to special device to lubricant technology, essence try development to make with maintenance technology, manage is changed metric detect with nicety technology, essence deepens patulous application technology to wait a moment to craft. The semifinished product productivity that essence of life changed technology of punch of tradition board makings to the technology is qualitative, can use board, , belt, coiled strip is used on special spirit strong opportunity take all sorts of appearance are puissant one model figuration develops the die of essence of life that presses makings board make a dimension and body precision is tall, strong tangent plane is bright and clean level off, can machine a photograph to rival with cutting. In recent years, the nicety of board makings is strong cut into parts (Feinschneiden) it is OK that patulous already size range of pipe bent is become essence of life is strong deep opening, heavy aperture, blind aperture, pressure protruding, press flower, embossing, Dui crowded, flange... wait for nicety to rush cut the compound treatment with figuration into parts, undertake all sorts of complex the accurate punch of board makings stamping workpiece (Feinstan-zen) technology. Be in common strong in cutting into parts, because there is certain space between punch and sunken model, make rush cut a strong tangent plane into parts to make distinct and coarse inclined plane, like the circle fall to expect and contain macroscopical taper to reach to round Kong Zedou collapse apparently horn and burr. Fall makings main aspects dimension is equal to size of sunken model point; Punching small end dimension is equal to punch point size. Measure strong cut into parts a dimension and use strong cut into parts when, fall makings it is with main aspects dimension is fiducial, and punching criterion with small end dimension is fiducial. If rush cut into parts strong tangent plane uses as coordinate face of face, datum plane, connection, motion face, adornment side... , have severe measure public errand and look precision requirement, especially when surface roughness of flatness, verticality, surface asks, expect especially of 3mm of thick T ＞ in thick board reach thick board makings is strong cut into parts, conventional technology uses cutting treatment to finish for base by punch namely. Since F.

The belt that Schiess invents V tine circle is puissant the essence that approach a limit develops a technology after 1958 progressively promotional rush at board makings nicety since cutting into parts, high accuracy is complex appearance, requirement of strong tangent plane is flat and bright and clean in thick board, thick board the spare parts can develop a law with this essence make, quality good, efficiency is tall, cause attention and try to be the first considers to popularize. After this, in succession a variety of essence grind in other country to the method try a success. The import that the home after 1965 carries transfer of technology and equipment of a complete set of and mould and simple and easy essence is done to rush on average punching machine and hydraulic press wait for a variety of ways, also begin promotion application essence to develop a technology, ceng Jingchong M=0.

The small modulus of 3 piece the spare parts such as gear, connecting rod, cam, ratchet achieves IT7 ～ 8 class precision serves as finished product spare parts to be used at the product to assemble directly. In recent years, energy strong technology basically is puissant tine the essence by the side of circle pressing is to craft in the production of mechanical and electrical products such as autocycle of electric equipment of domestic instrument appearance, switch, car get popularizing stage by stage, with 16mm of ≤ of Yu Jingchong T all sorts of thick plate expect stamping workpiece, obtained satisfactory beneficial result. Essence of life promoted punch the engineering technology standard of treatment to technical application, especially the difficulty that complex cutting processes a few external forms is very great thick board strong cut into parts, be like: T=7.

The spin machine brace of 5mm, 45 steel; T=12.

5mm intensity is as high as σ the aircraft stop a vehicle by applying the brakes of the alloy steel of tall manganese wear-resisting of B=750MPa piece... etc, rush by essence of life finish. Choice is strong (FB) academic basis and engineering technology level, and the characteristic that can see essence of life develops mould and device, to the promotion of punch technology the circumstance reachs the data of specific engineering technology that can replace cutting to machine. The promotion application our country of energy strong technology develops promotion application essence to develop a technology only then 1965, calculate the history that comes down to already had 40 years. And enter those who popularize application to popularize level to return truly should from 1979 by writer unit former academy of design of eleventh of one machine ministry suffers ministry bureau to entrust the whole nation that holding without stannum first after essence of life develops technical communication to meet, below the auspicious situation of reforming and opening, through transfer of technology, international technical communication, joint-stock use what FB essence develops a technology to pull in great quantities with foreign capital enterprise move, essence of domestic promotion application just begins to enter what develop quickly to popularize to the technology period. Former one of units that institute of Electromechanical of Beijing of one machine ministry studies the earliest to with development essence of life develops a technology as home, it is center of development of research of national spirit strong technology, strong lubricant of strong to essence of life theory and essence undertook fruitful research designed hydraulic pressure essence to develop strong opportunity of mould bases and 6300KN essence to wait, the promotion application that develops technology for domestic essence of life did a large number of works; Wuhan the Yangtse River is wired the power plant is the manufacturer that rushs to introduce technology of Swiss Feintool company and device earlier, more successfully with essence of average punching machine. Also be at present the essence of Wuhan area develops one of machining center. After this, shanghai, Suzhou and Guangzhou built essence of life to be mixed to professional factory factory holding course of study concurrently. Produces seed is strong in the majority is steel to rush character and 80% above are car, autocycle rush with essence of life, if Shanghai makes choice of motion company, Suzhou,wait for main production car to rush with essence of life to the factory. Foreign essence develops device, especially 4 world-renowned essence develop Switzerland company: The quality of producing strong opportunity of essence of life such as Feintool, Schmid, ESSA, Hydrel is good, but the price is high, domestic most company does not wish to buy, medium and small businesses is canned not afford. Although home is going up the century has after 70 time Harbin and inside river production of development of mill of two machine tools gives complete hydraulic pressure 3 change essence of life strong opportunity, but hydraulic pressure is sealed owe beautiful, specifications still is waited for improve. In last few years, develop technical scholar and expert organization to establish essence of an ancient name for China to develop technical limited company in Wuhan by domestic essence of life, create strong opportunity of essence of life technically and as full automatic as the HFB-2500A that development had Chinese own intellectual property the first times successfully in August 2002 strong opportunity of hydraulic pressure essence. With Wuhan at the same time manage is versed in the university builds essence of life to develop technical center in all. The strong opportunity of HFB series essence of life that at present this company already had 3 different specifications hands in an user to use. Already formed the productivity that produces per year 12 essence strong opportunity. The HFB series that this company makes is full automatic the main characteristic of strong opportunity of hydraulic pressure essence: Send makings, flotsam automatically to be cut automatically, mould safety defends, precision of energy strong spare parts is tall, strong tangent plane is bright and clean and flat. Strong opportunity of HFB series essence of life has nominal punching power from 1600 ～ 6300KN 6 norms can be offerred choose. The problem fine that promotion application essence faces to the technology rushs is the hi-tech in punch domain, in production company of of all kinds Electromechanical and home appliance product, when if product achieves moderate economy scale of production to undertake large quantities of quantities are produced, rational application essence develops a technology, can achieve beneficial result of safety of very good technology economy, profession. Promotion application essence develops a technology, need solves the following problem that face well: (1) renew an idea, it is with the person this, the noise in replacing cutting to machine punch to produce to more ground with essence of life exceeds mark presses a hand to break the person that point to to harm an accident with what happen from time to tome is disease making a person two difficult problem of first, do not have efficient pare way up to now. "It is with the person this, insist to be able to develop continuously " , in punch industry reflecting is above all " production must safe, safe for production " . Majority of the noise in punch exceeds mark to amount to 95dB (A) , deleterious worker is healthy. Strong opportunity of essence of life is drive of complete hydraulic pressure more, the mould has outside working area airtight defend screen, full automatic run, labor intensity is low, the 85dB that noise does not exceed a standard to set commonly (A) , can ensure safe production, working ground noise pollution is little, accord with " it is with the person this, can develop continuously " scientific progress view. And what essence of life produces T ＞ 3mm to craft is medium thick board, thick board, have part of complex external form, cutting etc machines a method to carry out large quantities of quantities to produce hard, however the advantage of strong hi-tech of essence of life, behoove popularizes application actively energetically, more substituent cutting treatment, realize low consumption of high grade high yield. (2) begin cooperation, mutually beneficial mutual benefit overcomes bequeath of planned economy period " big and complete, small and complete " , all things not the traditional idea of ask for help, begin large-scale cooperation, develop need essence of life and oneself outside the hardware that incapable essence develops treatment appoint cooperation. Begin essence of life to develop treatment alone, need has the capital investment with relevant technology all ready, huge form a complete set to develop device in order to buy high spirit; The technical staff that needs a batch of different major is propped up, cycle is long, devoted big, outside appoint the best thing to do of synergic can yet be regarded as. But manufactory of product of much to already achieving economic scale of production, essence to develop a need variety, several generous, be like hardware of electric equipment of car, autocycle, sewing machine, camera, switch, appearance, home appliance... etc, the spirit that establishs oneself develops manufacturing workshop (dot) as long as machine load rate is enough, benefit will be very good. (3) technology of form a complete set wants to catch up with, associated craft should perfect promotion essence to involve the engineering technology of class of technology of a lot of form a complete set and type of work and direct correlation and application to the technology, it is a giant and complex system project. With executive energy strong technology the technology of direct form a complete set basically has: The design that essence of life changes die of weights and measures technique, lubricant technology, essence to technology of raw material pre-treatment, manage and make reach repair essence of technology, CNC strong opportunity operation and maintenance technology are waited a moment. Class of these technology of form a complete set have domain of professional engineering technology and whole set of equipment, want to expertise personnel and technician undertake operation, cooperate essence of life to want the job to place. With promotion essence of life develops the technology treating gold with direct and related technique, the fine that matters to die of essence of life to provide steel and essence develop the development that special steel plants, mission that treat refine. In addition of forging stock of spare parts of work of die of essence of life forging, it is a difficulty big, the free forge with high demand engineering technology, need to get used to essence of life to develop technical demand, progressively and perfect. (4) the design of die of essence of life, make with repair specialization road and common photograph of complete steel die is compared, die of essence of life makes a technology ask taller, difficulty is greater, breed of the tall, essence of life that wants patternmaking, pointed equipment is much, workmanship is complex also. By the die of certain foundation production major factory makes die of essence of life more economy a few, advocate and recommend specialization manufacturing road. (5) the strong technology of education essence of life of professional technique talent is the hi-tech in punch domain and development direction. Country and enterprise or business unit and related technology class and scientific research orgnaization, the education that should pay attention to education major talent to reach pair of concerned professional to undertake essence of life develops technical knowledge and mastery of a skill or technique of purpose. Foster expertise talent from inside practice, if design as technical as what choose to popularize essence of life to develop a technology with education in production technical staff person from punch craft and die,just meet rapid introduction, get effective. (6) work out essence uses all sorts of GB GB to the technology, supply a gap concerns unit basis after 1986 German engineer association (VDI) the VDI-RichtlinieVDI3345Feinschneiden that publishs at drafting an editor by Swiss FeintoolAGLyss/schweiz company 1980, namely: Choice of VDI3345 of VDI- technology criterion is strong piece what published 1977 with afore-mentioned Feintool companies is new 2 edition " FeinschneidenHandbuchf ü Rdiepraxis " namely " Fein-tool economic essence of life develops manual " , wove machinist job essence uses occupation standard to the technology: JB/T6957-93 nicety is strong cut a craft into parts to weave nicety of principle, JB/T6958-93 rushs cut essence of a current technology condition, JB/T7714-95 into parts to develop a few occupation standard such as condition of lubricant dope technology. Although mark of these a few travel is put in a few problems, be like person meaning very much, but the guidance with will ten years develop a technology to popularize application to still rise to domestic essence of life certain and urge action. Nowadays already time passes and the situation has changed, domestic essence of life develops technical application, what a large number of increase production that get the product such as car, autocycle, home appliance and China become the world to make a center stage by stage is puissant pull move, built many essence to popularize essence of life to rush to machining center not only use, the ability that still begins him support is made full automatic strong opportunity of essence of life, need not only and the application that the national criterion that completely capable also, conditional work out fits the becomes series spirit of national condition to develop technical field develops a technology with standard and essence of directive whole nation and relevant commercial act. (7) team of contented scientific research, before increase essence of scientific research strength to answer to technical scientific research. Domestic promotion uses this new technology, started to began to consider to differ 1962 with Japan 1965 not quite. As a result of well-known " 10 years of Culture Revolution " , do not retreat then, come after reforming and opening, strong technology of promotion application energy just starts afresh again amble. Cause in essence of life strong technology scientific research and applied respect and Japanese photograph compare existence to wear very big difference; Japan introduced essence of life of Swiss much home to develop craft and essence to make patent technology to the mechanism 1964, began to create strong opportunity of essence of life 1966, already can make 250 ～ 25000KN at present 3 move essence of CNC of complete hydraulic pressure to develop each country of machine exit world. Actual strength of energy strong scientific research is abundant, be opposite at was being invented 1968 develop a way to sunken model essence, throw actual application quickly, very quickly 9 Euramerican countries bought this patent technology, japan still makes series now with CNC to rushing to sunken essence special spirit rushs machine. Under photograph comparing, a few essence of life of domestic the base of energy strong scientific research that although build,has and other places of Beijing, Wuhan up to now and Shanghai, Suzhou, Wuhan, Guangzhou develop machining center, the manufacturing industry that rapid to the whole nation and home development expands, scientific research army is too small, essence of life remains to increase scientific research strength to give to following a few difficult problem in the technology solve: A, thick board essence strong issue presses ply T to armor plate according to DIN of German industry standard in classification, t ＞ 4.

Of 75mm thick board choice is strong reach T ＞ 3 ～ 4.

In 75mm thick board choice is strong, still put in life of die of essence of life at present low, essence develops a quality not of stability and sound technology parameter and reasonable clearance value and cost of point round part wait certainly... . Structure of die of B, essence reachs component standardization, seriation, generalization. The technical condition of die of C, essence and check and accept a standard. D, other choice develops methodological development, innovation and promotion. The development of strong opportunity of essence of E, CNC, development and make. Especially the production of strong opportunity of essence of CNC of 32000KN above big tonnage. CNC Milling
