1、 I 连接板冲压模具设计 摘 要 模具是制造业的重要工艺基础，在我国模具制造属于专用设备制造业。本设 计是连接板冲孔、落料复合模设计，冲模的结构性能直接反映了冲压技术水平的 高低。选用材料时应考虑模具的工作特性，受力情况，冲压件材料性能，冲压件 的精度，生产批量以及模具材料的加工工艺性能和工厂现有条件等因素。冲床的 选用主要是确定冲床的类型和吨位。板料冷冲压加工是机械加工的一个重要组成 部分。它应用十分广泛。但由于传统的加工存在着冲压工艺方案选择不合理、冲 压间隙选择过大，压力机不相匹配等问题。本文就以连接板冲孔、落料复合模设 计主要介绍了冲压模具设计的全过程： 1经工艺分析工艺计算，间隙值的

2、选择，确定了该设计工艺流程及冲模结构 形式。 2同时对所设计的模具分别进行了分析说明， 3对压力机做出了合理的选择， 4整个过程采用 AutoCAD 软件绘制模具的二维装配图和个别零件图。 关键词：冲压模；复合模；连接片；冲裁间隙；冲压工艺。 II Connecting plate stamping die design ABSTRACT Die process is the important basis for the manufacturing sector, manufacturers in China die of special equipment manufacturing.

3、his design is Lianjie Ban punching, blanking compound die design, die directly reflect the structure of the high and low level of stamping technology. Optional material should be considered the work of mold, the force, punching pieces of material, the accuracy of press parts, molds and production qu

4、antities of materials processing plant performance and existing conditions and other factors. Selection of Punch Punch is determined the type and tonnage. Sheet metal stamping cold machining processing is an important component. It is very broad application. However, due to the traditional processin

5、g there is a stamping process options unreasonable, stamping gap choice is too large, presses do not match, and so on. In this paper, to Lianjie Ban punching, blanking the main compound die design stamping die design on the whole process: 1. The process of analysis, the gap value of the options, det
