Claims

[Scope of utility model registration request]

A forging die arranged on the machine base, a forging punch that is equipped on the front of the ram so as to face the forging die and is moved back and forth toward the forging die by the ram, and the above-mentioned forging punch behind the forging punch. In a heading forming machine, the forming machine has a wedge body that is vertically movably housed in a tapered groove formed in a ram, and the forging punch is moved back and forth by moving the wedge body up and down. a screw shaft fixed to the screw shaft; a drive member having an internal thread formed on the inner periphery to be screwed to the screw shaft and moving the wedge body up and down along the tapered groove by rotation; By detecting the amount of rotation of the drive member which is also meshed with and integrated with the gear member and the locking means which meshes with the gear member fixedly fixed on the outer periphery and locks the rotation of the drive member, A device for adjusting the longitudinal position of a forging punch in a forging machine, comprising: a display device that detects the amount of back and forth movement of the forging punch that is moved back and forth via the wedge and digitally displays the amount.
