Φ28外舌止动垫圈冲孔落料剪切级进模具设计
摘要：设计首先对冷冲压模具的基本成形机理及现状发展趋势做出简要阐释，指出冲模是一种低能耗高效率的产出方式，在综合分析产品工艺性指标及对比不同结构预案后，确定本次工件易采用连续模具的方案进行。
模具设计之前进行了排样结构设计和工艺计算两部分内容。第一部分通过排样参数选用和工件各工位的合理分解排布确定了包含冲裁，冲孔弯曲落料在内的多工位的合理结构，并以此为基础进行了第二部分，主要涵盖材料利用率，基本冲裁力参数，刃口精度公差等几部分的计算与校核，为后续模具结构具体实施打下基矗模具结构设计是在确保总体原则的情况下针对凸模，凹模，以及凸模固定板，辅助部件这几大方向完成了本体参数的设计和选用，最终将他们合理的装配，完成了本次工件级进模结构的设计。最后选用合理的压力设备与模具适配，以满足后续试模的需要。

Abstract
Abstract:The design firstly describes the basic forming mechanism and the current development trend of the die, and points out that the die is a kind of low-energy and high-efficiency output method. After a comprehensive analysis of product process indicators and comparison of different structural plans, this article is easy to determine. Use a continuous die program to complete the part design.
Before the die design, the design of the layout structure and the process calculationwere performed in two parts. The first part determines the reasonable structure of multiple stations including punching, punching and blanking, through the selection of the layout parameters and the rational decomposition of thework stations. The second part is based on this. Covers the calculation of the material utilization rate, the basic blanking force parameters, and the precision of the cutting edge, and lays the foundation for the subsequent implementation of the die structure. The die structure design is to ensure the general principle of the design of the body parameters and the selection of the punch, die, punch fixing plate, auxiliary components in these major directions, and finally theywill be reasonable assembly, completed this time Design ofwork piece progressive die structure. Finally, a reasonable pressure device and die are selected to meet the needs of the subsequent test mode.
