Contented and contemporary punch manufactures the new technology of demand

In production of contemporary car punch, technology of control of all sorts of new-style punch equipment, advanced mechanization system, new technology and die, intelligence by phase in, raised punch to produce efficiency and finished product quality greatly, reduced large quantities of cost that estimate production. Modern auto industry has scale of production to change, model batch change of small, breed is fast, much model in all the characteristic that the line produces, automobile body is enclothed also appear subsequently large change, the feature of unifinication, sex of ceaseless Xiang Rou turns technologies of these trend demand punch and equipment and automation way develops, gao Rou sex, efficient automation punch equipment is replacing traditional rigid product line stage by stage, make the main stream that world punch produces. The following author will is opposite respectively the technical progress of the respect such as control of craft of system of punch equipment, mechanization, punch and die, intelligence and its application make the introduction. Since punch facility is long-term, the manufacturing condition that traditional punch equipment stabilizes because of its assured the quality of stamping workpiece, the use of the mould is relatively abiding also, but the visible defect that devoid flexibility is means of this one production. Compositive the application that turns control technology, servo drive technology to go up in compressor brought more flexibility to punch production, large multitask compressor, flexible the history that the equipment such as punch transfer matic is producing in adapting punch. 1.

Compositive turn control to suit flexible the manufacturing requirement that change, all control function of compressor should be accomplished compositive change, the menu that realizes complete set mould thereby turns management, basically include slide block journey to adjust, journey of the adjustment of balancer atmospheric pressure, air cushion is adjusted and the parameter set of each link such as automation control system. Have the spot the spot bus line of function of module of sex of interconnection of equipment of communication network, spot, interactive operation, dispersive function, open mode the development direction that the technology is compressor control technology, urge action apparently to realizing automation to have. What compressor controls a system is compositive change the each control function that can realize all press and mould through single operation interface, include breakdown to diagnose, mould menu configuration, but switch of process designing spacing and mould monitoring and adjust etc, make the maintenance of equipment more convenient, and the effective working hours that increases compressor apparently. At present home produces use at the car large enclothed a production large punch line to had achieved contemporary international advanced level (see a picture 1) , used precision of much connecting rod to optimize compensation net of technology, couplet is full automatic the mould changes quickly timing of frequency of technology, vector communication advocate technology of control of carry on one's shoulder of discharge of protection of drive technology and overload of many bits of hydraulic pressure, technology of applied Ethernet network but with manufacturing couplet net, condition of real time supervisory equipment, have long-range communication and long-range breakdown to diagnose a function, the support that make a line sends makings system quickly, minutely producible 10 ～ 14 cars are large enclothe. Graph the line of 3 200t large punch that group of 2 machine tools produces 1 Jinan 2.

New-style servo compressor introduced servo drive the servo drive technology with very powerful adaptability, of the flexibility hydraulic press and mechanical compressor efficient organic ground combines the advantage rise, the enterprise can offer all sorts of differring stamping workpiece of size batch for their user, productivity rises considerably. Company of Japanese small pine and German easy strap a company to be developed in succession and already produced gave compressor of this kind of servo (see a picture 2) , be in our country at present home, motor Corporation of one steam Feng Tian and Guangzhou Feng Tian Motor Corporation already used this kind of device. Graph the characteristic with the most outstanding system of drive of servo of new-style servo compressor that 2 Germany easy forces a company to developed 2007 is: Electromotor joins each other with prejudicial brace gear directly, because the rotate speed of electromotor can adjust arbitrarily, can adjust arbitrarily thereby the athletic speed of brace orgnaization, random is accelerated or decelerate punch speed. The another big characteristic of servo compressor is to match a gender very tall. The electromotor rotate speed as a result of servo compressor is OK of stepless adjustment, because this is likely in punch process,implementation punch moves and adjust to the stepless that reduces force, make the working curve of compressor and the applied demand bearing that all sorts of differring match. Complete accurate exercise to assure brace, the user can pull the punch motion rate that delays treatment to come true to perhaps keep constant through decelerate, can improve the quality that plank machines not only so, and the service life that also can prolong a mould. Change and control passed the rotate speed of servo compressor to optimize a design reasonably, and was used compositive the module that change, according to modular the structure is made, when if do not need,using its servo function, this machine can resemble traditional compressor working euqally, maintain constant power and distance. 3.

Large multitask compressor can undertake flexible the large multitask that punch produces the top level that compressor represented technology of current international punch, it is the development direction that automobile body enclothes a strike out form to produce equipment. Large multitask compressor market mechanism, electron, control and detect the technology is an organic whole, can realize full automatic, intelligence to change, safety in operation, productivity is tall, make a quality tall, integrated cost is low, satisfied the need that auto industry big batch produces. Of course, the technology of compressor oneself and function also are in in practice of nearly more than 10 years be perfected ceaselessly and develop, be like: Drawing is versed in an application that uses mat of drawing of hydraulic pressure of gearshift much linkage mechanism, numerical control to replace bus line of machine of double dynamic pressure, spot to control a technology. Current, the famous car manufacturer of Europe and United States uses large multitask compressor and rail type are automatic mass-produced automobile body enclothes compressor (see a picture 3) , satisfy the highest precision of contemporary car stamping workpiece and exterior quality standard. Our country still uses large multitask without car production company at present compressor, its are main reason: The one-time investment that is equipment is larger; 2 it is domestic car manufacturer starts later, the punch equipment with existing enterprise still is enlisting in army period, this also is going up somehow restricted technology of punch of our country car rise. Graph the multitask that manufacturer of 3 abroad some car uses compressor 4.

Flexible punch transfer matic is flexible punch transfer matic mostly by double use drawing compressor or sheet of much connecting rod moves drawing compressor and 5 sheet move 4 ～ compressor forms automation line, produce large automobile body to enclothe, security is high, punch quality is good. Next makings systems on automation are arranged on product line, by the machine that tear open a battlements, wash oiled machine, manipulator of makings of makings machine, fluctuation goes up in be opposite (robot) , move back and forth (retroflexion) composition of deferent and automatic conveyer, from semifinished product on expect stamping workpiece gets offline to be finished automatically entirely. Manufacturing metre is highest it is 6 ～ 9 times / Min. Whole punch line grows 60 ～ 80m to control, need 6 ～ about 7 jockey people. What some enterprises use is international advanced high speed is compact model punch line, can improve the manufacturing efficiency of punch quickly. Board expect to current and advanced optics is used to photograph in be opposite have fixed position like the system. Drawing compressor chooses mat of drawing of numerical control hydraulic pressure, every advanced automation unit matchs a manipulator, leave out move back and forth deferent device, shorten carry a distance, reduce the span of compressor, manufacturing metre can amount to 10 / Min. As the ceaseless aggravate that market of our country car competes, the exterior quality of the car reachs his the precondition that immanent quality makes market of contend of home of each automobile factory already was the fact that does not dispute, accordingly, using the producer type of mechanization, automation to undertake punch is produced is the most efficient way that improves car exterior quality. 5.

The car punch enterprise that debugs production of compressor big batch should be configuration of transfer matic of every large punch to debug compressor, in order to shorten the time trying a model of metallic figuration mould, raise the actuate of large punch line to lead. Debug compressor to basically choose machine of proof pressure of hydraulic pressure high speed and drawing machinery compressor, the mould experiment time that attends in compressor of machinery of type of production especially can decrease 80% , have enormous applied value. The development trend of compressor of machinery trying a model is to use deployed drawing of numerical control hydraulic pressure the drawing of mat, much connecting rod that has function of parameter setting and condition memory compressor. The mechanization of product line of the research and development of automatic punch product line, punch transforms mechanization system, of machine tool of punch of the makings on the large vacuum that is used at production of car side boarding make the flying progress that promoted auto industry. To company of production of domestic car stamping workpiece, the most valuable technology promotion behaves the automation in stamping workpiece to carry centrally, automation delivers device to go up and on punch equipment makings automation is mixed in be oriented punch to produce a course with the product. Because be in,be out of shape the limit of technology of the hydraulic pressure in machining a process is broken through not easily, because this can want beneficial result to mechanical automation only, and cannot want beneficial result to mechanical automation in punch process merely, also ought to want beneficial result to the domain beyond punch engineering technology, to new stamping workpiece casting die of deferent means, Xiang Chong gets offline means wants beneficial result, demand beneficial result to all fields that can acquire economic benefits. New-style compositive type conveys quickly system (see a picture 4) can be convey directly between compressor and compressor, manufacturing metre can amount to 12 ～ 15 times / Min. Manipulator arm extreme but automatic process designing undertakes angle is adjusted, with getting used to a mould model groovy position. Be in large in the manufacturing process that reachs oversize stamping workpiece, compose can be in solid and strong stamping workpiece conveyer not only large work punch and double a punch (punch two finished product) wide application receives in producing a course, and also can be in process of car component production wide application. Deferent system will give stamping workpiece of type of move about arm punch device changing to mould respect supports with huge and be helped quickly, while it realized punch mould and workpiece, output, laid a foundation to realize muti_function punch product line thereby. Graph craft of punch of 4 deferent systems and mould change in world car product diversiform times, mould diversification and mould change the characteristic with short cycle becomes highlight particularly, raised new requirement to punch engineering technology at the same time, brought car stamping workpiece to produce those who machine engineering technology to change. 1.

Punch is versed in ordinal car stamping workpiece has good craft sex and economy, the cent of assembly of the work ordinal number that measures the important sign of its level to have stamping workpiece, automobile body piece the element such as the structure of amount and dimension size, stamping workpiece. The work ordinal number that reduces punch process is meant reduce stamping workpiece amount of number, economic tool, simplify personnel of the deferent device of punch process, cut operation and equipment cover an area of an area to wait, it is the admirable step of managing investment and specific power consumption, so strong suppress builds business to be able to be versed in punch ordinal design serves as the important way that reduces a car to make cost, not hesitate even the requirement that improves products plan to satisfy workmanship, the reasonable automobile body assembly that still adopts quantity large measure at the same time is divided piece, if rectify a type automobile body to control side panel and roof cover board, can make car appearance more beautiful and practical already, reduce wind resistance, can reduce stamping workpiece amount and solder point again, reduce cost effectively. When the punch technology that makes work, those who handle process is dispersive with concentration it is more complex issue. It depends on characteristic of requirement of appearance of the batch of workpiece, structure, quality, craft. To the car stamping workpiece that is big batch production normally, ought to adopt the plan that working procedure centers as far as possible, use compound or class undertakes punch into the model, improve productivity already so, can accomplish safe production again. Practice experience makes clear, to compound model, the working procedure amount that is centered to a pair of mould is unfavorable and too much, it is 2 ～ commonly 3 working procedure, most 4, receive a standard to class, work ordinal number of concentration is many somes OKer, because its model signs an undertaking,the position limits freedom of compose is spent bigger. 2.

Craft of many punch mould as intermediate of the promotion of technology of punch of side wall of automobile body whole and compressor mesa increase, punch craft also got rapid development, door, ala child board wait for stamping workpiece the one standard from in the past is single a development produce for double chamfer model, manufacturing efficiency twice rises, newest already developed the shell plating inside door to use 4 model groovy die production, manufacturing efficiency broke up one time again. When crop is bigger, use many at the same time punch, can make cost of raw materials and mould cost, treatment cost get reducing, to figuration craft, also be helpful for semmetry of material stress, meet an emergency even, still improved manufacturing efficiency, reduced the sources of energy to use up. Double the newest development trend of a production is board of inside and outside is produced at the same time, its advantage is: Manufacturing amount matchs, still can send solder to install a line to be pressed in time at the same time close, content shedding is smooth, convenient. 3.

Class enters assorted die to apply generally in developed country auto industry already into modular class, its advantage is productivity cost of tall, mould is low, do not need board makings to cut. With multitask the photograph of model of a flight of stairs that uses on compressor is compared, class receives a standard but managing the cost of 30% , but the restriction that its application accepts the case hardening of drawing deepness, strip edge stuff that direct and transmits, basically use at drawing deepness to compare easy simple part. Intelligence controls a technology in recent years, development of technology of control of punch production intelligence is very rapid, it goes up in the foundation of unifinication of material, craft, the online control that the basis already had material and process of treatment of punch of implementation of technical data library or intelligent control (also say " from adaptive control " ) . Build online testing system to material or craft parameter above all, when when material function or craft parameter happening changes or generation fluctuates, by automatic testing system (sensor and signal changeover system) the instantaneous value of a quantity of online and affirmatory relevant parameter, be analysed through computer simulation and optimize software (for example system of method of artificial nerve network, expert) the optimal craft parameter after affirmatory parameter changes is combined. After automation system adjusts craft parameter, can realize punch process from adaptive control. New manufacturing data accumulates the technology that can make sequel machine a process further to optimize a foundation gradually. The development trend that the last word has bigger flexibility or flexible punch technology and equipment will get used to small lot, much breed, mixed flow to produce demand of mode and market diversification, individuation, strengthen an enterprise to answer ability to vicissitude of the market quickly.
