    • A thread rolling machine is disclosed wherein a continuously adjustable thread means is used to adjust the relative phase timing between two thread rolling dies and the feeding of a workpiece by the feed means. This timing substantially eliminates any mismatch of thead rolling by the two dies. A double ended thread rolling machine is also disclosed with timing of the two dies relative to the feed of a workpiece accomplished at one end of a workpiece and then the continuously adjustable thread means is used to adjust the relative phase timing of the thread rolling operation on the other end of the workpiece. The above description is merely one form of the invention and is not to be construed as limiting on the scope of the invention.
    • 公开了一种螺纹滚丝机,其中使用连续可调的螺纹装置来调节两个滚丝模具之间的相对相位定时和通过进给装置进给的工件。 该定时基本上消除了由两个模具滚动的任何不匹配。 还公开了一种双端螺纹滚丝机,其中相对于在工件的一端实现的工件的进给的两个模具的定时,然后使用连续可调螺纹装置来调节螺纹滚动操作的相对定时 工件的另一端。 以上描述仅是本发明的一种形式,而不应被解释为限制本发明的范围。
