资料简介:毕业设计-接片倒装结构连续模的设计,共32页,11422字,附设计图纸、3D截图、任务书、文献综述等摘要:本次模具设计的零件为冲裁弯曲件。各工位有相互的尺寸关系,且尺寸的位置和精度要求较高,如果采用普通单工序模或复合模冲制生产的话,需要多副模具,多个操作人员才能完成而且产品质量和生产效率都低。采用多工位连续模可以提高材料利用率和模具的使用水平,节省设备,且保证了较高的产品质量和生产效率,以获得最佳的经济效益。本模具性能可靠,运行平稳,能够适应大批量生产要求,提高了生产质量和生产效率,降低了劳动强度和生产成本。关键词:连续模;冲孔;落料;折弯;排样Design of connection meet piece flip structure continuous modeStudent: Yuan LeiTutor: Zhou Guangyong(Oriental Science &Technology College of Hunan Agricultural University, Changsha 410128)Abstract:This time the task of design is Punching Bending parts. There are mutual relationships between each part where higher accuracy of the size and location is required. If using the common single procedure or the composite modulus punch production, we need more moulds and operators. At the same time, the quality and the efficiency of our products are low. Selection of the Multi-Position Progressive Dies can improve the material utilization and the level of using molds. It also can save equipments and guarantee high quality and the efficiency of our products to get greatest economic benefits. This mould has reliable performance, and it can operate smoothly. In additon, it meets the requirements of mass production, which will improve the quality and the efficiency of our products, and also reduces labor intensity and production costs.Key words: Progressive Dies; punch holes; fall the material curving; bcnding; arrangement目 录摘要 1关键词 11 前言 22 零件的工艺性分析 22.1形状 22.2尺寸 32.3冲孔、冲槽时工艺 32.4表面质量 32.5材料性能 32.6制定冲压工艺方案 32.7条料宽度 43 材料利用率的计算 54 冲压力计算及设备选择 54.1冲裁力的计算 54.2卸料力的计算 64.3设备的选择 65 压力中心计算 76 模具结构草图 87 凹模的外形尺寸确定 98 冲裁间隙的确定 109 毛坯尺寸 109.1主要刃口尺寸计算 1010 卸料装置的选用 1111 模具零件设计 1211.1工作凸、凹模设计 1211.2导正孔凸模的设计及加工 1211.3中心孔凸模设计 1511.4冲槽凸模设计 1711.5落料凸模设计 1811.6其它零件设计 2111.6.1 各用途的螺钉、销钉的选用 2111.6.2模柄的选用 2211.6.3模架的选用 2211.6.4各模板的尺寸 2211.6.5侧刃的设计 2312 设备校核 2312.1凸模抗压能力校核 2312.2凸模纵向抗弯曲能力校核 2412.3核对模具开模行程 2413 结 论 25参考文献 26致 谢 27
