我厂在Z12-16大型冷镦机上,用异形轮送进代替了棘轮送进。其结构及工作原理见图1,摆架顺时针回转时,异形轮依靠摩擦力楔紧摆架和送进轴,迫使送进轴顺时针回转。当摆架反转时,异形轮在摆架内壁上滑动,送进轴则不转。即送进轴只能作顺时针间歇回转,完成送进运动。弹簧装入异形轮 I plant in the Z12-16 large cold heading machine, with a special round of delivery instead of the ratchet into. The structure and working principle shown in Figure 1, swinging frame clockwise rotation, shaped wheel relies on friction wedge swing frame and feed shaft, forcing the feed shaft clockwise rotation. When the pendulum is reversed, the special-shaped wheel slides on the inner wall of the pendulum and the feed shaft does not rotate. That is fed into the shaft can only be intermittently clockwise rotation, to complete the movement into. Spring loaded shaped wheel
