度調節装置。A peripheral cam is fixed to a camshaft that rotates in conjunction with the reciprocating motion of the ram, and a pair of fingers is supported in a freely openable and closable manner at the lower end of a tube shaft that reciprocates between the surfaces in front of adjacent dies. A direction in which an operating rod that engages with the pair of fingers and opens and closes the pair of fingers by moving in the axial direction is inserted into the tube shaft, and one end of the rod engages with the peripheral cam on a support fixed to the frame. pivotably supporting a lever that is biased to swing freely, and engaging the other end of the lever with the operating rod;
In the heading machine in which the pair of fingers are opened and closed in conjunction with the ram, the lever is provided with a retaining member whose tip protrudes from the corresponding surface of the support and whose protruding length can be adjusted; The swinging angle of the lever is adjusted by bringing the tip of the engaging member into contact with the support body and separating the one end of the lever from the small radius portion of the cam surface of the peripheral cam, so that the pair of fingers 1. An opening adjustment device for a finger in a heading machine, characterized in that the device is configured to adjust the maximum opening of a finger.
