（毕业设计论文）《7.00T轮辐的模具设计》.doc

PAGE 摘 要 本毕业设计的课题来源于机械制造有限公司提出产品要求的题目，主要任务是设计生产7.00T轮辐的模具。 本设计主要围绕冲压模具设计展开，设计宗旨为降低生产成本，提高生产效率，提高模具寿命，而且要求操作方便，维修简单。 本文设计的冲压模具采用单工序冲裁模，按照分配任务主要完成轮辐边孔的冲裁设计。此工序利用冷冲压技术可以达到高的加工要求获得良好的经济性。根据生产要求，采用手工送料方式以毛坯的中心孔用定位销定位。为了便于操作降低模具成本采用弹性卸料方式冲件和废料采用凸模直接从凹模洞口推下的下出件方式。 本文对零件加工工艺进行力详细的分析，对模具的工作零件进行力必要的设计计算，特别是刃口，及冲裁间隙分析计算、选择。根据要求，对辅助零件标准化选择。最后加工出的模具能达到企业的要求。 关键词：模具；冲裁；冲裁间隙； Abstract The design of the subject from Daye manufacture the limited company product requirements, main task is to design production 7.00 T spokes mould. The main contents of this design is about the design of the stamping dies , Its aim at lower the production cost , increasing production efficiency ,lift the molding tool life span and request for operate convenience , fix briefly and easily .  This paper designs the stamping mould adopts single procedure punch die, according to the distribution of the main task of the cutting edge of the hole. This process using cold stamping technology can achieve high processing requirements to obtain good economy. According to the production requirements, manually feed on the edge with positioning pin blank. In order to facilitate operations using elastic mould cost reduce discharging mode stamping and waste from the punch directly under the push of dies.the hole under a way out. . This paper parts processing technology force, a detailed analysis of the working parts of mold design and calculation of the necessary force, especially the blade, and the cutting clearance analysis and calculation, the choice. According to the requirements of auxiliary parts, standardization of choice. Finally the mould processing can achieve business requirements.
