一、概述长期以来,在机械、仪表、电器和轻工等行业,对冲压模具的制造是比较困难的。不论生产批量大小,制造冲模均以钢为材料,其工艺复杂、成本高、周期长,而中小企业往往不具备足够的加工能力。因此,试制一种新产品,等到模具造出来,再加之验证试验,往往需要很长时间,这对尽快搞好产品的更新换代都是很大的障碍。对于多品种小批量生产或新产品试制来说,近年来,国内外都在研制既经济又简易的冲压模具。 First, an overview For a long time, in the machinery, instruments, electrical appliances and light industry and other industries, the manufacture of stamping dies is more difficult. Regardless of the production batch size, the manufacture of die are made of steel, the process is complex, high cost, long cycle, and SMEs often do not have enough processing power. Therefore, the trial of a new product, until the mold to create, coupled with the verification test, often takes a long time, which is a great obstacle to upgrading the product as soon as possible. For many varieties of small batch production or trial production of new products, in recent years, both at home and abroad are developing both economical and simple stamping die.
