设计简介
本成形模具加工设计的对象是车体安装连接板。
本文首先分析了该零件的结构工艺性，并通过分析各种冲压工艺方案，制定了落料-拉深-冲孔一次成形的冲压工艺方案，分析确立了模具的结构形式。然后进行了模具总体设计，包括操作和定位方式、卸料和出件方式、送料方式、导向方式等问题。接着进行了冲压设备的选择计算，主要零件的理论分析计算与设计以及标准件的选择。根据以上分析和计算结果，设计出了落料-拉深-冲孔一次冲压成形复合模。最后介绍了本套模具的装配和调试问题以及模具的工作过程。
本模具可以实现车体安装连接板的快速冲压成形，既可保证加工质量，又可提高生产效率。本模具的设计思路和设计过程对其他零件的冲压模具设计亦有参考价值。

Abstract
This design aims to the forming die designing for vehicle body mounting connection board.
Firstly, the processability of the product structure of the connection board is analyzed, and the pressing process program of blanking-drawing-piercing in one forming process is formulated through analyzing different pressing process programs, and the structural configuration of the die is analyzed and established. Then the general design for the die is carried out, which includes operating and positioning method, material discharging and part discharging method, feeding mode, guiding mode, and so on. Following, the calculating and selecting for the pressing equipment is carried out, and the theoretical analysis and calculation and design for the main parts and the selection of the standard parts are carried out. The blanking-drawing-piercing compound die in one forming process is designed according to the above analyzing and calculating results. At last, the assembly and adjusting for this die and the working process of the die are introduced.
The pressing forming for the vehicle body mounting connection board can be realized quickly by this die, which not only ensures the machining quality, but improves the production efficiency. The designing method and process of this die provides referring values for other parts’pressing dies.
