最近,我们在厂党委的领导和车间支部的大力支持下,生产工人等的密切配合下,试制成功了冲制薄片金属板料的聚氨酯橡胶冲模。一付模子能冲制从0.05毫米到0.5毫米不同厚度的薄片金属零件,较好地解块了薄片材料冲模的制造中长期不易解决的技术问题。过去,0.05毫米以下的薄片材料的冲孔落料复合模,要求凸凹模间隙很小,甚至接近于无间隙,所以有“无间隙冲裁”之称。由于间隙小,制造困难,修理也很不方便,既费工又费时,而且往往达不到要求,特别对于尺寸较大,形状较复杂,曲线较多的零件的冲制,要感到困难。 Recently, with the strong support from the leaders of the party committee of the factory and the workshop branch, the production workers and other closely cooperated, we succeeded in trial production of polyurethane rubber stamping dies for sheet metal stamping. A pair of molds can be punched from 0.05 mm to 0.5 mm in different thickness sheet metal parts, the better deblocking sheet material die manufacturing difficult to solve in the long-term technical problems. In the past, the punching and blanking compound die of sheet material below 0.05 mm required that the punch and die clearances were very small, even close to no gap, so there was “blanking without gaps”. Due to the small gap, the manufacture is difficult and the repair is very inconvenient, which is laborious and time-consuming, and often fails to meet the requirements. In particular, it is difficult to process the parts of larger size, more complicated shapes and more curves.
