【正文】 n a centralized sensor board, then put it precisely fixed in the mold outlet, namely the punch clamping board, using sensor data monitoring stamping process, and through the controller get timely treatment, guarantee the quality of the stamping. 汽車制造中沖壓工藝的新發(fā)展 汽車制造中有 60%70%的金屬零部件需經(jīng)塑性加工成形，沖壓加工是 完成金屬塑性成形的一種重要手段，它是最基本、最傳統(tǒng)、最重要的金屬加工方法之一。joint processing, also in two sides stamping workpiece machining, which has greatly enhanced the work efficiency, have data show that the module type stamping makes processing cost can fall to 40% 50%. The current module type stamping device integration is very high, in width is 300MM size range can arrange of 35 mold, through the roof top of stamping die for independent type series of control, is formed namely die of integrated control. The whole system programmable in WINDOWS user interface and menu under implementation, programming involves mould along the lateral positioning shaft servo drive positioning, strip inspection correction and longitudinal feeding positioning, stamping quality followup inspection, punching machine。 and virtual (5) die amp。s plenty of auto parts, such as engine exhaust muffler, hollow tube bending and camshaft, the oil pan, engine stents, frame structure, horizontal longeron etc, it is by stamping technology positively precision, multifunction, high efficiency and energy saving, safe cleaning production direction, stamping workpiece manufacturing technology level and quality, in great degree of automobile manufacturing quality and cost has direct impact. Socalled stamping technology refers to the adaptability of the stamping to handicraft, namely the design of stamping in size, size accuracy and benchmarks, structure shape stamping processing of pliance with technological requirements. Automotive stamping parts should be good technological characteristics, and the economy, measure the level of the important symbol has stamping process number, body assemblies block number and size, stamping structure, and other factors. Reduce the number of punching process procedure, that means less stamping tooling quantity, number of packages, save simplified punching process of conveyors, Narrows the operators and stamping area, is to save investment and energy consumption extremely good measures, so stamping manufacturers can put punching process reduce vehicle number design as the important way to manufacture cost, even ? Modern stamping development and research of the major subjects include: (1) module type and control。 stamping (2) new material and posite stamping processing new craft。 mould manufacturing technology, (6) stamping process of automatic monitoring and instability mechanism analysis and so on . Module type stamping Module type of prominent advantages in stamping the stamping processing system of the flexible and efficient production of anic unifies in together. Flexible meaning a broader, such as stamping the geometry of the various demands, so long as can be obtained through the freedom to programming, which reflects the processing shape of flexible. And as both to be suitable mass single variety stamping production, more for small batch multispecies processing play advantage, and also show flexibility. Oerall, module type stamping waterholding point is: (1) the stamping process can be replaced rapidly bination to improve production efficiency。 the adjustment and Condition monitoring and versatility. When stamping reconfigure or alteration, these changes would be parameters and controlled system to store, next time query and invoke. Declarations Die data include the punch and their bination tags, punch bination in X, Y o f die and mould shaft Numbers coordinates and other information. Figure 3 shows programmable punching system, figure in A standard mould transverse axis, can undertake servo dynamic to stamping area, B for the supporting shaft with punching die, C, D for spare axis to orange roll type with material are feeding. And submillimeter stamping project And submillimeter stamping refers to the automotive stamping accuracy control at 0 to MM within the scope of the traffic in the past, and manufacturing error of 2MM pared, is a very big enhancement. This is an improving punching quality and manufacturing technology as the goal of integrated project. The project with 2MM engineering are all in the late 1990s America QiCheJie conduct largescale research project. Socalled the car is 2MM engineering knowledge, body assembly size changes within 2MM quantity control, greatly in strict in the original 8MM error range. Stamping processing forming technology affect auto body manufacturing level is one of the key factors, the American experts worked in a car assembly line to over 50 cases field analysis shows that, cause body size error change many reasons, stamping itself size caused by error accumulation 23 percent, its main reason is that the traditional based on experience and original technology based on low level of mold design and manufacturing. And submillimeter stamping is the center of precision stamping with increasing agility two goals, precision is to make the stamping size accuracy control in 0 mm or and submillimeter level, the key is to control body stents, pillar on the pieces of the feet, and make changes in body covering parts, such as partitioned degrees by whole leftright side plate and the top cover plate, etc. Increasing agility meaning is refers to reduce stamping prajapati was preparation time up to 30%, including tooling design, manufacturing and tooling, sample preparation time, in order to achieve greatly shorten the purpose of the new models manufacturing cycle, this project diet are diecutting and assembly integration design, stamping system agile de
