摘 要

在日常生产和制造业中，特别是钣金加工方面冷冲压已经占据了主导地位，它具有生产快、市场投放能力强、加工精度较高等特点而被广泛使用。

本篇文章叙述了盖板零件的设计，其中主要包括了模具的选择、模具内部标准件的选择、凸模的设计计算、凹模的设计计算、加工时各个作用力的大小、压力机的选择。简述了零件的制造过程、冲压模的结构设计、零件的公差分析、对该类型的模具前景浅谈。

关键词：冲压模具、冲裁、弯曲

ABSTRACT

Stamping production by the mould and press finish machining process, compared with other processing method of its stable quality, good interchangeability.Machining surface quality is high, the shape of complex parts.High efficiency, saving material.So the stamping die in the actual industrial production can be used widely.

Blanking, punching, bending structure design and working process of compound die were introduced, through the analysis of the technology, uses blanking bending, punching through, the top pieces, pressing force, stripping force, bending strength calculation, determine the type mold. The posterior mold using derivative-scale, blanking die with insert structure, waste discharged from the slot die.

Key words : Pressing mold、Cutting、Bending
