For the problems of complex die structure, low utilization rate and high manufacturing cost of plate and wire material products in the whole stamping process, Through the analysis and research on product materials, structure sizes, forming process and so on, firstly, the layout process design of special-shaped shrapnel was carried out, and the forming process of automatic feeding of plate and wire materials, multi-station progressive die and CNC bending was adopted. Secondly, through the research on the characteristics of forming process and forming equipment of plate and wire materials, the continuous forming of products was guaranteed by the multi-station progressive die stamping method, and the bending accuracy was ensured by the compound forming method of cutting and CNC bending. Finally, the compound forming die structure with stamping mechanism and bending mechanism of special-shaped shrapnel was designed. The production tests show that it not only ensures the accuracy of product and saves materials, but also shortens the research and development cycle and reduces the cost. Thus, the advancement, feasibility and practicability of forming process for plate and wire materials are proved to lay a practical foundation for the application and promotion of the technology.
