摘要：冲压是通过模具对板料施加一定的压力或者拉力，使板料能够塑性成形，有时候对板料施加剪切力使板料分离，从而能够得到一定尺寸、形状和性能的一种加工零件的方法，冲压加工需要研究冲压工艺和模具两个方面的问题。如今冲压件在各个行业中均占有相当大的比例，特别是在汽车行业、电机行业、仪表行业、军工等行业占有非常大的比例。41671

本篇文章主要介绍了给定冲压件，利用NX中的级进模向导设计一副模具以达到对给定的冲压件进行冲裁的目的，其中包括了制件的冲压工艺性分析和确定，冲模的设计和计算，主要有相关工艺的计算，凸凹模零件以及主要零部件结构设计，还有模具总体设计等方面。通过对冲裁件的工艺分析，可以使用最小的材料消耗，最少的工序数量和时间，从而稳定的获得符合要求的产品，除此之外要使模具结构要简单，模具寿命要求高。最终可以减少劳动量和生产的成本。本文较为详细的介绍了定位方式的选用、冲压工作零件的设计计算和卸料装置等的设计。
通过了对给定冲压件的分析，结合冲压模具的各种资料进行一步步的冲压模具设计，在设计的过程中还要注意各个冲压过程的优化、排样是否合理，使得定位能够更加的准确，最终使得材料的生产效率能够提高。

The forming process and die design of the lighting lamp holder
Abstract: Stamping and punching is a manufacturing method in which we gain some size, shape and performance by pressure or tension to sheet metal forming or exerting shear force on sheet to separation. Stamping and punching machining required to study two issues, stamping process and die. Currently, stampings in all kinds of industry account for a large proportion, especially in the automotive, electrical, instrumentation, military, household appliances and so on.
This paper describes design of complex stamping in a progressive die stamping, including analysis of the workpiece stamping process and definition, stamping die design and calculation, the main is relevant process calculation, convex, concave mold parts and the main components structural design, mold design as well and so on. By process analysis to hedge and cutting pieces, you can use the smallest material consumption, minimum quantity and working hours, stable work meets the requirements of quality products, and to make the mould structure simple, long service simple, long service life of the mould, so can reduce the labor and cutting costs. Describes in detail selection of positioning way, the design and calculation of the stamping die parts, unloading device design, etc.
Through the analysis of a given stamping parts, combined with various data of the stamping die for stamping die design, step by step in the design process pay attention to the optimization of stamping process, layout design is reasonable, the more accurate positioning, so as to achieve the aim of material productivity high.
