摘　　要：针对金属弹片产品在加工成形时加工工序冗繁、加工效率低以及需要多次定位等问题,通过对产品材料、结构要求、成形工艺等方面的分析研究,采用板线材间歇自动送料+连续冲切+数控折弯的成形工艺,提出一种金属弹簧双向弹片的成形设备,包括冲切机构和成形机构,冲切机构用于在板线材上冲切多个依次连接的预制品,成形机构用于成形弹片。通过生产试验可知,此成形设备不仅可以保证产品的精度、节省材料,还可以缩短研发周期、降低成本,证明了板线材成形设备结构的先进性、可行性和实用性,为该技术的应用推广奠定了实践基础。In order to solve the problems of cumbersome processing procedures, low processing efficiency and the need for multi positioning when metal shrapnel products are processed and formed, through the analysis and research on product materials, structural requirements, forming processes, etc., the forming process of the intermittent automatic feeding of plate and wire materials, continuous punching and numerical control bending was adopted. A metal spring bidirectional shrapnel forming device was proposed, which included a punching mechanism and a forming mechanism. The punching mechanism was used for punching a plurality of sequentially connected pre-products on the plate and wire materials, and the forming mechanism was used for forming elastic pieces.Through the production test, the forming device can be known that the forming device can not only ensure the accuracy of product and save materials, but also shorten the research and development cycle and reduce the cost. It proves the advancement, feasibility and practicability of forming device structure of plate and wire materials, and lays a practical foundation for the application and promotion of the technology.
