我厂生产DT-65VB录音机芯。以前在冷冲模上一直采用外形、工件孔或工艺孔定位,不能连续冲,误冲较多,质量差,不安全。改进后,采用连续模和新的活动定位,坯料连续进给,提高了生产效率,现简介如下(图1); 条形坯料经导向板进入模具,侧刃定位销4由于压簧8的作用,高出于凹模平面档 I plant DT-65VB recording production. Previously in the cold die has been the use of shape, hole or hole positioning process, can not be continuous Chong, more mistaken, poor quality, unsafe. Improved, the use of continuous mode and the new activity positioning, continuous feed stock, improve production efficiency, are as follows (Figure 1); strip blank through the guide plate into the mold, the side edge of the positioning pin 4 due to the role of compression spring 8 , Higher than the die plane file
