摘要
本次课题打火机金属外壳的冷冲压模具设计,通过这次设计,进一步熟悉冲压模具的设计流程运用落料、冲孔、弯曲等冲压工序设计冷冲压成形模具,需要解决很多的关键问题,对零件进行工艺分析,进行冲压工艺方案及模具结构方案设计和对冲压模具零部件工艺参数进行参数选择及验算,绘制冲压模具装配图和零件图。需要运用机械、材料成形、冷冲压模具、计算机二、三维设计等多学科的知识,需要相当广阔的知识面和较高的专业水平。通过对零件进行工艺分析和工艺参数计算,根据零件所需冷冲压工序设计出连续冲压模具,同时运用AutoCAD绘制二维模具装配图和零件图还得同时对部分零件进行了加工工艺分析。该零件复杂且尺寸不规则,这对模具设计和展开排样提出了较高的要求,特别是弯曲过程,需要合理的安排工艺,巧妙的设计冲模来解决,对于部分不关键的零件可适当降低尺寸公差要求,设计中尽可能使用标准件,有利于设计成本的降低。

Abstract
This topic lighter metal exterior cold stamping mould design, through the design, further stamping mould design process using blanking, punching, bending stamping process design of cold stamping mould, needs to solve the key problems of many parts, technical analysis, stamping process scheme and the die structure and design of stamping mould parts process parameters parameter selection and calculation, stamping, assembly and detail drawings. Need to use machines, materials, stamping, molding, cold, 3d design puter science knowledge, need quite a broad knowledge and professional level. Through the analysis of the technology of parts and the process parameters calculation, cold stamping parts needed to process pound stamping mould design, and using AutoCAD assembly drawing two-dimensional mould parts and also have also made for parts processing analysis. ponents plex, the size of irregular of mold design and layout puts forward higher requirements, especially the bending process, need reasonable arrangement of the clever design process, stamping parts, to solve the key parts for not properly reduce dimension tolerance requirement,design as far as possible, to use standard design cost reduction.
