内容简介：

河南机电高等专科学校毕业设计说明书/论文落料、冲孔复合模设计摘要 (中文) 本模具设计题目为落料,冲孔复合模,此零件需二道工序完成.体现了复杂零件的设计要求,内容及方向.具有一定的设计意义,通过对该零件模具的设计进一步加强了设计者冲压模具设计的基础知识,为设计更复杂的冲压模做好了铺垫和吸取了更深该的经验. 本设计运用冲压模具设计与制造工艺基础知识,首先分析了零件的外形,尺寸,精度要求,进行了工艺分析,考虑到此零件为零件,因此采用复合模工艺方案.然后根据零件的外形尺寸计算毛坯总体尺寸,设计压力中心最后计算出工作部分尺寸,模具总体尺寸,总体尺寸包括工作零部件的结构设计,卸料装置的设计以及固定零件的设计与运用.本模具的特点是落料,冲孔复合模. 此时由落料凹模,凸凹模进行落料,然后冲底孔.关键词: 复合模 落料凸凹模The Punch Holes Superposable Die Desig AbstractThis mold design topic for the punch holes superposable die, this components need two working procedures to complete. Has manifested the complex components design request, the content and the direction. Has certain design significance, through further strengthened the elementary knowledge to this components mold design which the designer ramming mold designs, for designed more complex flushes the die to complete the upholstery and to absorb a deeper this experience.This design utilization ramming mold design and the manufacture craft elementary knowledge, has first analyzed the end cover components contour, the size, the precision request, has carried on the craft analysis, considered this components are the circular components, Then the basis components external dimensions computation semifinished materials overall size, a design the center of pressure last count is present at work makes the partial sizes, the mold overall size, the overall size including the work spare part structural design, the dumping device design as well as the fixed components design and the utilization. This mold characteristic is the punch holes superposable die.this time by falls the material concave mold, the convex-concave mold carries on falls the material, then fl
