本发明公开了一种滚丝机，其中连续可调的定时螺杆用于相对于与静止模具协作的旋转模具的瞬时位置来调整工件的进给相位。这一定时基本上消除了两个模具滚压螺纹的任何不匹配。可旋转的定时螺丝通过移动承载凸轮从动件的钟形曲柄杠杆的支点来调整凸轮从动件相对于进给凸轮的圆周位置。正时螺丝的旋转调整凸轮从动件相对于进给凸轮的周边位置。上述描述仅是本发明的一种形式，不应被解释为对本发明范围的限制。
A thread rolling machine is disclosed wherein a continuously adjustable timing screw is used to adjust the phase of the feed of a workpiece relative to the instantaneous position of a rotary die cooperating with a stationary die. This timing substantially eliminates any mismatch of thread rolling by the two dies. The rotatable timing screw adjusts the peripheral position of a cam follower relative to a feed cam by moving the fulcrum point of a bell crank lever on which the cam follower is carried. Rotation of the timing screw adjusts the peripheral position of the cam follower relative to the feed cam. The above description is merely one form of the invention and is not to be construed as limiting on the scope of the invention.
