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
