模具冲模的设计说明书.doc

设计说明书 摘 要 分析了冲压件的结构和成形工艺，计算了毛坯尺寸和冲压力。为了提高弯曲件的生产效率，设计了集三工序为一体的落料弯曲冲孔复合模的结构，经过工艺分析、结构设计，论证了其可能性，保证了制品的质量。 在模具设计中,为了提高速度和效率,充分利用已经掌握的知识和资源。利用曲面设计功能快速求出曲面的面积。利用冲模设计手册软件版快速设计冲压模具,并对模具的强度进行检验。实践证明,确实提高了设计的速度和效率。本模具设计中,由于卸料力较大,采用了组合弹簧力较大的优点解决了这一问题。在模具结构中,用顶板做凸模的定位元件,由于配合定位的距离小,容易造成凸模的折断,因而设计了凹模导向凸模,增强了凸模的强度。 关键词：；冲孔；弯曲；落料 复合模；模具结构 Abstract The structure and processing property of bellows?oil?conservator end cover for?transformers were analyzed. The blank dimensions and pressing force were calculated. The compound die of cut-tandem-punch combined with three procedures is designed in order to improve the production of end cover. The article proves its availability through technological analysis and structural design to guarantee products’ quality . In mold design, in order to improve pace and efficiency, fully utilize knowledge and resource that has already been grasped. Utilize Pro/E curved surface design function ask , produce area of curved surface fast , utilize the design manual software edition of the trimming die to design and press the mould fast, and the intensity to the mould is examined. Practice has proved , have really improved pace and efficiency designed. In this mold design, because of unload material to be strength relatively heavy, adopt , make up spring loud advantage solve this problem. In the mould structure, make the localization component of the protruding mould with the roof, the distance making a reservation is little because of cooperating, apt to cause protruding rupture of mould, design concave mould pour , to protruding mould , strengthen protruding intensity of mould. Key words: cut；tandem；punch；compound die；die structure 目 录 摘 要 1 Abstract 2 1 绪 论 9 2 模具设计 10 3 模具类型的确定 12 4 冲裁间隙的选用 14 5 工艺计算 15 5.1 材料排样及材料利用率的计算 15 5.1.1 材料排样的选用原则 16 5.1.2 确定板料规格和裁料方式 17 6 计算冲压力 18 7 模具压力中心的确定 19 7.1 模具压力中心的确定 19 8 计算凹凸模刃口尺寸 20 9 冲裁及弯曲的部件及零件设计 22 10 压力设计的选择 30 11 模具经济以及技术上的分析 31 结 论 32 致 谢 33 参考书目 34 1 绪 论 作为一个即
