Automobile manufacture stamping process of new development
Automobile manufacture has a 60-70% of metal parts must be approved by the plastic processing forming, stamping process is complete 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, theres 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, multi-function, 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.
So-called 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 compliance 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 composite stamping processing new craft;
(3) special stamping technology;
(4) computer simulation stamping mold testing technology; and virtual
(5) die amp; mould manufacturing technology,

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 multi-species processing play advantage, and also show flexibility. Oerall, module type stamping water-holding point is:
(1) the stamping process can be replaced rapidly combination to improve production efficiency; mould
(2) due to its strip for belt and masking belt device, can save another set feeding blanking process,
(3) achieved great work pieces the non-stop machining,
(4) can both independent and can become series of control combination dies action can continually stamping processing;
(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 run-time 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 non-stop string amp;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 follow-up inspection, punching machine; the adjustment and Condition monitoring and versatility.
