贝氏体钢板冲裁模的无间隙冲裁对不规则形状的薄板冲裁件有其独到之处。如图1所示,零件是我厂某产品的锁紧垫圈,材料为08号钢,料厚1.2毫米。有一定的精度要求。原钢模具因凸凹模内腔间隙不均匀,冲件毛刺严重,故改用贝氏体钢板复合冲裁模。从冲裁件的出料来看,无论单工序模和连续模都是从凹模后方推出工件,而复合模 Bainitic steel blanking blanking blanking of the irregular shape of the sheet blanking pieces have their own uniqueness. As shown in Figure 1, the part is a lock washer for one of our products. The material is 08 steel and the material thickness is 1.2mm. Have a certain accuracy requirements. The original steel mold due to uneven punch cavity cavity uneven, serious burr red pieces, it switched to bainitic steel composite blanking die. From the blanking piece of material from the point of view, both simplex process and continuous mode are derived from the back of the workpiece die, and composite die
