2、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。本论文对以上问题进行了解决。 关键字:关键字:冲压模 复合模 连接板 冲孔落料 第 III 页 connection plate punching, blanking compound die design Abstract Die process is the important basis for the manufacturing sector, manufacturers in China die of speci
3、al equipment manufacturing. This design is connection plate 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 pre
4、ss parts, molds and production quantities of materials processing plant performance and existing conditions and other factors. Selection of Punch is determined by the type and tonnage. Sheet metal stamping cold machining processing is an important component. It is very broad application. However, due to the traditional processing there is a stamping process options unreasonable, stamping gap choice is too large, presses do not match, and so on. In this paper,the probl
