Claims

[Scope of claim for utility model registration] Feed for a thread rolling machine equipped with a feed plate that feeds the material supplied from the feed groove between a fixed die plate and a movable die plate to process and manufacture bolts. In the device, a conduit is provided above the moving path of the feed plate to allow the material to flow through the central through hole, and the feed plate moves the material discharged from the conduit to the fixed die plate. A material feeding device for a thread rolling machine, characterized in that the material is fed between a die and a plate. The conduit is supported by a holding ring of a clip means attached to the bracket of the thread rolling machine stand, and the lower end of the conduit is held at the lower end of a vertically adjustable arcuate control spring screwed onto the outer wall by the holding ring. The material in the through hole is held in contact with the material in the through hole through the slot in the peripheral wall, and when the feed plate feeds the already discharged material between the fixed die plate and the movable die plate, the arcuate plate control 2. The material feeding device according to claim 1, wherein the spring is placed on a push rod that operates in synchronization with the movement of the feed plate so as to release the material by loosening its abutting force. The push rod is configured by means of an interlocking rod movably mounted on the fixed die plate.
The feed plate is provided parallel to and above the feed plate so as to reciprocate synchronously with the feed plate, and the other end is pressed against the arcuate plate-shaped control spring to transfer the material discharged by the feed plate to the fixed die plate. and movable die.
Moves in synchronization with the operation of feeding between the plates,
3. The material feeding device according to claim 2, wherein the material feeding device according to claim 2 is configured so that the material held in contact with the control spring plate is released and dropped by pushing the control spring plate. An arc-shaped chute is provided above the conduit, and a vibrating plate is attached to the upper end of the chute for supplying the material, and the lowest end of the chute, where the material descends along the sliding groove on the surface of the chute, is placed at the center of the conduit. Claim 1 or 2 characterized by a configuration corresponding to the open end of the through hole.
The material feeding device described. The push rod is formed of a rod bent at one point, and due to the positional change due to the rotation of the bent point and the reciprocating angle of the interlocking rod,
4. The material feeding device according to claim 3, wherein the material feeding device is configured such that pressing the other end of the arcuate plate-shaped control spring against an appropriate position can be adjusted.
