如图所示,钢丝钩切断成形模具的底座1上固定有模板2,模板2上开有一个小孔,能使钢丝穿过小孔而止于限位螺钉3上。孔的高度位置恰好使钢丝在轴4和轴11之间通过。当压力机滑块向下运动时,在臂7斜楔的作用下,轴4、11伸出,托住钢丝。当齿条8与齿轮5开始啮合时,凸模9下行到切断钢丝。接着,转动的齿轮5带着销轴6旋转,在
As shown in the figure, the base 1 of the wire hook cutting and forming mold is fixed with a template 2, and a small hole is opened in the template 2 so as to allow the steel wire to pass through the small hole and stop at the limit screw 3. The height of the hole just allows the wire to pass between the shaft 4 and the shaft 11. When the press slider moves downward, under the action of the wedges of the arm 7, the shafts 4 and 11 extend to support the steel wire. When the rack 8 and the gear 5 start to mesh, the punch 9 descends to cut the wire. Then, the rotating gear 5 rotates with the pin shaft 6
