Claims

[Claims for Utility Model Registration] (1) A circular rotating die with a large number of thread grooves formed on the outer circumferential surface, and a circular rotating die with a large number of thread grooves formed on the inner circumferential surface to connect the rotary die to a predetermined rolling space. A material in a rotary screw thread rolling machine having arc-shaped stationary dies that are spaced apart and facing each other, and a material supply mechanism that supplies bolt material into the rolling space at a predetermined timing in synchronization with the rotation of the rotating die. A rotary screw rolling machine, characterized in that the supply device is provided with a lock mechanism that locks the material supply mechanism to stop the material supply operation of the material supply mechanism in synchronization with the rotation of the rotary die. Material supply device. (2) The material supply mechanism is synchronized with the rotation of the rotary die between a pushing position where the bolt material is pushed into the rolling space at a predetermined timing synchronized with the rotating die and a retreating position where the bolt material is retreated from the pushing position. The locking mechanism has a pushing member that is intermittently driven by a cam mechanism that rotates, and a locking mechanism that is detachably provided to the pushing member and holds the pushing member in a state separated from the cam mechanism when engaged. The lock lever is composed of a lock lever and an engaging means for engaging the lock lever with the pushing member, and is further provided with an engagement release means for releasing the engagement of the lock lever with the pushing member by the engaging means. A material feeding device for a rotary screw rolling machine according to claim 1, which is a utility model registered as claimed in claim 1.
