摘要： A worm is formed by rolling to reduce the number of processing steps while ensuring the worm accuracy satisfactorily. A work material is positioned between a first rolling die (100) and a second rolling die (101) by rotation of the rolling dies and a servomotor (76) for feeding the work material. When the lead angle of a worm is large and there is a large difference between the finished diameter and the blank diameter, the lead angle changes during the progress of rolling process, resulting in occurrence of through-feed. A slide plate (55) is freely slidable on a slide (53). Therefore, when through-feed occurs owing to the lead angles of the first and second rolling dies (100) and (101) and the workpiece, the slide plate (55) slides freely, and this is detected with a detecting sensor. The rotation of the first and second rolling dies (100) and (101) is stopped. Then, the first and second rolling dies (100) and (101) initiate reverse rotation, and at the same time, the slide plate (55) also initiates movement in the reverse direction. Thus, rolling is started. Thereafter, similar processing is repeated to perform rolling.

摘要： A motor shaft for a rotational-to-direct motion converting motor has a rotation stopping portion formed in a plate shape, and a screw portion formed in a columnar shape. In addition, the motor shaft has a hole, arranged in an end portion of the motor shaft in a longitudinal direction of the motor shaft, for positioning the motor shaft in a form rolling. Therefore, a position shift or a phase shift of thread ridges formed on the screw portion can be prevented.

摘要： A tangential rolling attachment (20) for a machine tool, broadly includes a body (21); a pair of arms (22L, 22R) having their proximal marginal end portions (23L, 23R) pivotally mounted on the body and having distal marginal end portions (24L, 24R). The arms are biased to move in opposite angular directions such that the distal marginal end portions thereof will be urged to move away from one another. A roll (28L, 28R) is pmounted on the distal marginal end portion of each arm for imparting an action to a workpiece when the attachment is moved to tangentially engage the workpiece. A wedge (29) is mounted on the body for movement relative thereto in a direction parallel to the longitudinal axis of the workpiece. An actuator (30) mounted on the body for selectively moving the wedge relative to the body to vary the spacing between the axes of the rolls. The improved rolling head may also incorporate a quick-release mechanism (33L, 33R) for mounting a roll on the arm of the machine tool attachment.

摘要： In a rolling die for forming a ball screw by tolling for example, a biting portion is formed on one end of a straight portion while a relief portion is formed on the other end. Further, the helical protrusion on the biting portion and the helical protrusion on the relief portion each become continuously and gradually smaller as distancing away from the dancette portion on the straight portion. The dancette portion on the various portions are continuously formed using only one grinding wheel with its grinding lead being changed.
