我厂有很多板金零件需冲模加工。在板金零件品种多、外形复杂而产量又不大的情况下,如何能简化模具结构,并使之典型化,减少模具设计制造工时及模具材料,从而降低成本、缩短生产准备周期、提高冲模安装效率,是一个重要课题。以往我们采用装在万能模座上的板模(如图1),以简化模具结构、减少模具零件,但在压力机上安装及调整仍较麻烦,尺寸较大零件的模具依然很重。使用板模虽然减少了模座、模柄、导柱、导套等零件,但仍需专用卸料装置及凸模夹板,所用凸凹模较厚,加工工时大,对产
I have a lot of sheet metal parts need to die processing. How to simplify the mold structure, make it typical, reduce the mold design and manufacturing man-hour and the mold material, so as to reduce the cost, shorten the production preparation cycle, and improve the die-mounting Efficiency is an important issue. In the past, we used the die plate (Figure 1) installed on the universal die base to simplify the die structure and reduce the die parts. However, the installation and adjustment of the die plate in the press machine are still troublesome. The dies of the larger parts are still heavy. Although the use of die plate mold base, die stem, guide post, guide sleeve and other parts, but still need special unloading device and punch plywood, punch and die used thick, large working hours, the production
