摘要冲压生产是一种先进的金属加工方法。
它是利用模具和冲压设备对板材金属进行加工，通过冲压生产可以获得所属要的零件形状和尺寸。
本课题是盖板零件的冲压模具的设计。
根据设计零件的尺寸、材料、生产批量等要求，分析零件的工艺性，确定冲裁工艺路线方案，从而设计一套复合模具，在保证工件的尺寸和形状位置精度要求的同时，尽量的提高材料的利用率和生产效率。
随着计算机技术的不断发展，采用CAD/CAE/CAM一体化技术可以准确、快速的完成模具设计制造。
本课题以给定的零件来选择合理的模具，通过几种不同的模具比较最终定位采用复合模，工艺过程分为落料、冲孔、弯曲成形，根据工艺要求确定了排样图，从而设计了凸凹模，确定各种力，确定模架查找标准件。
本文主要是介绍说明了盖板零件成形的各个工序及其模具的设计及尺寸计算，在结构设计的同时，对主要零件的设计和装配要求技术进行了分析。
设计时考虑到模具设计合理、简单，便于制造和修模，有利于缩短模具生产制造周期，降低成本。

Through stamping production, we can get the shape and size of the parts which we need.This topic is about the design of the stamping mould for the cover parts. According to requirements of part size, material, production batch, etc. we should analyze the manufacturability of parts, and determine a medium manufacture route to design a set of compound mould. We not only should ensure the size and shape of the workpiece position accuracy requirements, but also try to improve material utilization and production efficiency. Along with the unceasing development of computer technology, it is accurate and fast to use the integration technology of CAD/CAE/CAM to complete the die designing and manufacturing.This paper mainly illustrates the flat parts forming process and the mold of each design and size calculation, the structural design of the main parts, meanwhile, the design and assembly required technologies are analyzed. When designing, we consider that the die structure should be reasonable and simple to manufacture and repair and advantageous to reduce the manufacturing cycle of die production and the costs.Keywords cover parts; The process route; Composite modulus; Mold designII目录摘要 (I)Abstract (II)第1章绪论 ............................................................................................... - 1 -1.1我国模具技术的现状及发展趋势 (1)1.2冲压模的现状与发展趋势 (2)1.3外国模具工业的发展状况 (3)第2章零件的工艺性分析.................................................................................... - 5 -2.1设计题目内容 (5)2.2材料的性能 (5)2.3冲压成型工艺分析 (5)2.4冲裁工艺方案的确定 (6)2.5模具结构型式的确定 (6)2.6排样的确定 (6)2.6.2确定条料步距 ............................................................................. - 7 -2.6.3画出排样图 ................................................................................. - 7 -2.6.4毛坯材料利用率的计算 .......................................................... - 7 -2.7冲裁压力中心的确定 (7)2.8各部分工艺力的计算 (8)2.8.1落料力、冲孔力的计算 .......................................................... - 8 -2.8.2弯曲力的计算............................................................................. - 9 -2.8.3卸料力、顶件力、推件力、切断力的计算 ...................... - 9 -2.9总力的计算 (10)2.10压力机的选择 (10)2.11本章小结 (11)第3章模具结构的计算 ..................................................................................... - 12 -3.1凸、凹模刃口尺寸的计算 (12)3.1.1 确定凸、凹模间隙及制造公差 ......................................... - 12 -3.1.2落料凸、凹模刃口尺寸的计算.......................................... - 12 -3.1.3 冲孔时凸凹模刃口尺寸计算 .............................................. - 13 -III3.2选用模架、确定闭合高度及总体尺寸 (14)3.3模具各零部件的设计与计算 (15)3.3.1弯曲凹模和冲孔凸模的设计 .............................................. - 15 -3.3.2凸凹模的设计 (17)3.3.3 凸模固定板的设计 ................................................................ - 17 -3.3.4垫板的设计 .............................................................................. - 17 -3.3.5定位零件的设计 ..................................................................... - 17 -3.3.6模柄的选择 .............................................................................. - 18 -3.3.7连接件与紧固件的选取 ....................................................... - 18 -3.3.8下模板的确定 ......................................................................... - 18 -3.4模具材料的选用 (19)3.5本章小结 (19)第4章模具的装配图的设计............................................................................ - 20 -4.1零件的技术要求 (20)4.2装配技术要求 (20)4.3复合模具的安装调试要求 (21)4.4主要组件的装配 (21)4.5模具的装配图 (22)4.6模具的工作过程 (22)4.7本章小结 (23)第5章冲压模具零件加工工艺的编制.......................................................... - 24 -5.1凹模加工工艺过程 (24)5.2凸模加工工艺过程 (24)5.3卸料板加工工艺过程 (26)5.4凸模固定板加工工艺过程 (26)5.5上模座加工工艺过程 (27)5.6下模座加工工艺过程 (28)5.7导料板加工工艺过程 (28)5.8本章小结 (28)结论............................................................................................................................ - 30 -致谢............................................................................................................................ - 31 -IV参考文献 .................................................................................................................. - 32 -附录1 ........................................................................................................................ - 33 -附录2 ........................................................................................................................ - 36 -V第1 章绪论1.1 我国模具技术的现状及发展趋势我国模具工业近年来发展很快。
