摘要
本课题为托板冲孔落料复合模的设计,本文介绍的模具实例结构简单实用,使用方便可靠。本套模具的设计不是以复杂模具的设计为主,而主要是对模具设计知识的系统学习和设计的练习,以达到掌握冲压模具设计的基本技能的目的。
首先,对零件做整体的分析。包括:材料的使用、精度的要求、工序的要求以及成本的要求等。为了降低成本,对排样方式进行了合理的设计;其次,对零件整体进行工艺设计。通过工艺目的的设计、工序的顺序设计、压力机的选择等来实现所要达到的要求;再次,想要保证制件精度的要求,就要考虑模具刃口尺寸的计算。因为刃口是冲制工件的主要工作部分,刃口处的精度就决定了制件的精度,就必须根据公差来进行精确计算。

Abstract
The topic is the chain plate punching pound mold design and the mold of article described an instance is simple and practical, easy to use and is reliable. This mold is not primarily designed plex design, but mainly on a systematic study of mold design knowledge and practice, in order to achieve the purpose of master the basic skills of stamping mold design.
First of all, do a thorough analysis for the parts, which include the using of the material, the requirement of accuracy and the requirement of working procedure and costs and so on. For declining low cost, proceeded the reasonable design to the row kind method. Secondly, do processing design for the whole parts and the purpose by craft designing and order of the working procedure and by the choice of punching machine. Thirdly, consider the calculation of size of the mould cutting edge in order to meet the need of accuracy. Because the cutting edge is the main working part of the punching processing, the accurate cutting edge guarantees the accurate parts. So you needed to tolerance do accurate calculation.
