汽车工业当前的研究重点是:降低产品成本;减少能耗;提高新车的安全性和环境相容性。如果,原材料、动力和工资仍将上涨,要限制汽车的成本,只有降低每个零件的成本。为此目的,需要实行生产流程的合理化,例如减少零件的加工工序和材料的消耗等。本文所述的精密冲裁工艺(以下简称精冲)是实现这一目的的最好手段。事实上,用它制作的汽车零件已大规模地取代了那些成本高的锻造、铸造和粉末冲金的汽车零件。这是因 Current research priorities in the automotive industry are: reducing product costs; reducing energy consumption; and improving the safety and environmental compatibility of new vehicles. If, raw materials, power and wages will continue to rise, to limit the cost of the car, only to reduce the cost of each part. To this end, the rationalization of the production process is required, for example by reducing the processing steps of parts and the consumption of materials. The precision blanking process (hereinafter referred to as fine blanking) described in this article is the best way to achieve this goal. In fact, car parts made from it have largely replaced those expensive forged, cast and powder-blasted automotive parts. This is because
