磁轭冲片的冲制是水轮发电机制造的关键工艺之一.由于磁轭冲片形状复杂、孔距要求高,所以较理想的办法是用全复式冲模一次冲出.这样,质量好、生产效率高、劳动条件好.但是采用全复式冲模冲制,冲床吨位要大.我厂生产的六万瓩磁轭冲片(图1) Magnetic yoke punching is one of the key technologies in the manufacture of hydroelectric generators.As the shape of the yoke is complex and the pitch is high, it is better to use the all-in-one die to punch out at one time. , High production efficiency, good working conditions, but the use of all-duplex stamping punch, punch tonnage to be large. I plant the production of 60,000 瓩 yoke punch (Figure 1)
