我厂每月都要生产数套不同形式的小电动机硅钢片复式冲模,其中槽形阳模加工工作量很大,操作技术复杂。现在我们试用冷压法代替钳工加工槽形阳模成功。其主要过程简介于下:图1所示四种具有典型截面的槽形阳模,长度一般由30～40公厘,数量每套由15～50件不等,最多的有90件阳模。 I plant each month to produce several sets of different forms of small motor silicon steel compound die, in which a large slot-shaped male mold work, the operation of complex technology. Now we try to replace the fitter cold groove machining positive groove type male success. The main process outlined in the following: Figure 1 shows the four typical cross-section of the groove-shaped male model, the length is generally 30 to 40 mm, the number of each from 15 to 50 ranging from up to 90 male model.
