摘要： A machine is disclosed which incorporates a timing control for modifying the timing of a starter for feeding work blanks to a forming station and which features a manual control for applying a supplementary rotary input into a spindle operated differential having an output drivingly connected to the starter for effecting a desired change in the timing of starter movements in relation to a circular die fixed to the spindle at the forming station. In addition, a starter drive selector is provided having a manual interlock for selectively adjusting the number of starter operations for each revolution of the spindle and its circular die.

摘要： A significantly simplified, rugged attachment is provided for a standard thread rolling machine for quick and easy re-rolling of threaded parts for producing high quality threads. A pressure foot is mounted between an open end of a feed chute and the starting end of a fixed die and is biased toward a confronting movable die for urging a threaded part into mesh with the die surface of the movable die when it is moving toward a rear limit position. Such mesh between the threaded part and movable die is effected before the threaded part is pushed by a starter blade into matched rolling position against a starting end of the fixed die and thereafter the moving die reverses its direction of movement to stroke into a forward limit position to effect precision re-rolling of the previously threaded part to produce a high quality finished part.
摘要翻译：为标准螺纹滚丝机提供了一个显着简化，坚固的附件，用于快速和轻松地重新生产高质量螺纹的螺纹零件。压力脚安装在进料槽的开口端和固定模具的起始端之间，并被朝向相对的可动模具偏压，用于当其移动朝向可动模具时将螺纹部分与可动模具的模具表面啮合后限位。螺纹部分和活动模具之间的这种啮合是在螺纹部分被起动机叶片按压到相对于固定模头的起始端的匹配的滚动位置之前进行的，然后移动的模具将其运动方向反转到行程的前进极限位置以实现先前螺纹部件的精密重新轧制以产生高质量的成品部件。
