某型号接线盒支架冲压模具设计
摘  要
本文设计了某型号接线盒支架的冲压模具，由于这个零件不属于回转体零件，中间有一个盒形的支架，所以在计算毛坯尺寸的时候比较困难，因为展开形状不是很规则，所以计算出毛坯尺寸很关键。
这个零件需要制造出来设计了三套模具，分别为落料模具，拉深模具，冲孔模具。 
本设计中介绍了某型号接线盒支架冲压模具工艺分析工艺方案的分析和制定，排样图的设计，总的冲压力计算及压力中心的计算，刃口尺寸的计算，凸模、凹模或凸凹模结构设计以及其他冲模零件的结构设计，绘制模具装配图和工作零件图，编写设计说明书，制作工作零件机械加工工艺过程卡，注意凸、凹模的配合加工。有关工艺参数的计算，如：冲裁力、卸料力的计算。冲孔模具结构设计中有关于非标准件的计算与设计等等。

A certain type of junction box base stamping mould design

Abstract

This paper introduces the design of a certain type of stamping mould boxes base , Because the parts does not belong to axially symmetrical parts , There is a box shape among the base , So in the calculation of blank dimensions is difficult , Because spread shape is not very rules, so calculate blank dimensions is a key point.
The parts that need to be made out three sets of mould design , Separately for blanking mold, deep drawing mould, punching die.
In this design introduced a certain type of junction box base stamping mould design ,the craft plan formulation, arranges the specimen map design, the always ramming strength computation and the center of pressure computation, the cutting edge size computation, the spring, the rubber computation and selects, the raised mold, the concave mold or the convex-concave mold structural design and all that die the components structural design, draws up the mold assembly drawing and the work detail drawing, the compilation design instruction booklet, fills in the work components machine-finishing technological process card, raised pays attention to, the concave mold coordinate processing. The calculation concerning craft parameter, such as: Hurtle to cut the dint and unload the calculation of anticipate the dint. The blunt bore  molding tool structure designs the medium  calculation and the design etc. concerning not standard piece.
Key Words: Positioning；Punchedhole；Flection； Convex； Cave mold.
