Φ35圆螺母止动垫圈冲孔落料复合模具设计
摘要：冲压模具在实际工业生产中应用较为广泛，其中倒装冲压模具可以大大提高劳动生产效率，具有及其重要的技术进步意义与经济价值。本文结合直径35mm的止动垫圈冷冲压成形模具整体结构设计，通过比较不同工艺方案，确定最终工艺方案、并计算冲压力和刃口尺寸等工艺参数，绘制相应的模具简图，
在模具设计方面，首先运用三维绘图软件，对零件进行三维造型，然后对其进行成形工艺的分析，确定复合模具的生产方式。选用合理的搭边参数值，确定排样的方案。基于以上几点进行了涵盖冲压力在内的力参数计算，并对整体结构和零件进行设计。
本课题完成止动垫圈制件的倒装冲压模具设计，应用AutoCAD绘制零件二维加工图纸，以达到加深对冲裁件模具结构工艺性理解的目的。设计借鉴了先进倒装模具的设计生产经验，成功地突破磨具设计中的疑难点，顺利实现了止动垫圈零件的一次冲裁完成。

Design of compound die for blanking and blanking ofΦ 35 round nut stopwasher
Abstract: the stamping die iswidely used in the actual industrial production, amongwhich the reverse stamping die can greatly improve the labor production efficiency, and has the important technical progress significance and the economicvalue. Combinedwith the overall structure design of the cold stamping die for the stop
washerwith diameter 35mm, the final process plan is determined by comparing different technological schemes, and the process parameters such as punching pressure and edge size are calculated, and the corresponding die diagram is drawn.
In the aspect of die design,we first use 3D drawing software to model the parts, and then analyze the forming process to determine the production mode of the compound die. Select reasonable parametervalue to determine the layout scheme. Based on the above points, the force parameters including impact pressure are calculated, and thewhole structure and parts are designed.
In this subject, the design of the stamping die for the reversewasher is completed, and the two-dimensional drawing of the parts is drawn by AutoCAD in order to achieve the purpose of deepening the understanding of the structure of the die. The design and production experience of the advanced upside die is used for reference, and the difficult point in the design of the grinding tool is successfully broken, and the stopwasherzero has been successfully realized. One blanking of the piece is completed.
