【正文】 example, forming from the graph visible at effective media bees the punch. The hydraulic internal highpressure forming technology pared with other stamping technology, there are several obvious advantages: (1) the forming process can one processing out like axle, top cover, doorcase and other large and plex 3d geometric shapes of workpiece, (2) because of liquid in the forming process cooling effect, make the workpiece is a cold strengthening, won than ordinary stamping workpiece machining higher strength, this makes allowing a thinner plank, to make the work more lightweighting。 (5) dies with programmable and the flexible characteristics. A module type stamping processing system by a with control function module type of cold stamping press, coil strip send into outfit porch, strip correction machines and programmable feeding device, etc. The stamping system at runtime can undertake stamping transverse displacement, strip feeding positioning, die repeat operation and automatic adjustment work step punching adjustment etc multiple functions. Because the stamping process programmable stamping, make this kind of module type stamping system can adapt production requirements, flexible in same strip on March different workpiece and batch production, realizing mixed nonstop string amp。 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 organic 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. In a nutshell, module type stamping waterholding point is: (1) the stamping process can be replaced rapidly segment mold to improve production efficiency。 (4) puter simulation stamping mold testing technology。 stamping (2) new material and posite stamping processing new craft。 Automobile manufacture stamping process of new development Automobile manufacture has a 6070% of metal parts must be approved by the plastic processing forming, stamping process is plete metal plastic forming a kind of important means, it is the most basic, the most traditional, the most important one of metal processing method. Such as vehicle body all kinds of covering parts, car support pieces, structure strengthen pieces, there39。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
