精冲技术在六十年代初就开始在中国开发和推广,目前用于生产的精冲件有600种左右,全国拥有精冲压力机约40台,最大达800吨,最小25吨,其中3/4从国外进口。精冲件的履盖面已开始从仪器,仪表,办公机械、电器、开关行业,扩展到汽车、摩托车、起重机械、纺织机械、工量具、液压元件、航空器等制造部门。具体进展按六个方面分述如下:
Fine blanking technology began to be developed and promoted in China in the early 1960s. Currently, there are about 600 fine blanking pieces for production. There are about 40 fine blanking presses nationwide, with a maximum capacity of 800 tons and a minimum of 25 tons, of which 3 / 4 imported from abroad. The surface coverage of fine blanking parts has been expanded from the instruments, meters, office machinery, electrical appliances and switch industries to the manufacturing departments of automobiles, motorcycles, lifting machinery, textile machinery, measuring tools, hydraulic components and aircraft. The concrete progress is divided into six aspects as follows:
