Claims

[Claims for Utility Model Registration] (1) A plurality of forging stations equipped with opposing dies and punches, and a plurality of forging stations that reciprocate in the direction in which these forging stations are lined up to sequentially transfer the material to each of the forging stations. A material transfer device for a multi-stage heading forming machine, which has a material transfer chuck, and a camshaft that rotates in synchronization with the forward and backward movement of the punch, and a camshaft that corresponds to each of the material transfer chucks. and a plurality of driven members that open and close each of the material transfer chucks by being driven in accordance with the rotation of each of these opening and closing cam members,
The camshaft is movable in parallel in a direction away from the driven member, and the pair of opening/closing cam members are individually phase adjustable with respect to the camshaft, and each of the pair of opening/closing cam members a gear member fixed to rotate integrally with the cam member;
a drive gear that engages with the gear member as the camshaft moves in a direction away from the driven member; and a rotation operating means that changes the phase of the pair of opening/closing cam members by rotating the drive gear. and,
A material transfer device for a multi-stage heading molding machine, comprising a fixing means for fixing each pair of opening/closing cam members on the camshaft to the camshaft. (2) A multistage machine having a plurality of forging stations equipped with opposing dies and punches, and a plurality of material transfer chucks that pass back and forth in the direction in which these forging stations are lined up to sequentially transfer the material to each forging station. A material transfer device for a type heading forming machine, which includes a camshaft that rotates in synchronization with the forward and backward movement of the punch, and a pair of opening/closing chucks provided on the camshaft corresponding to each of the material transfer chucks. A cam member and a plurality of driven members that open and close each material transfer chuck by being driven in accordance with the rotation of each of these opening/closing cam members,
The camshaft is movable in parallel in a direction away from the driven member, and the pair of opening/closing cam members are individually phase adjustable with respect to the camshaft, and each of the pair of opening/closing cam members a gear member fixed to rotate integrally with the cam member;
a drive gear that engages the gear member as the camshaft moves in a direction away from the driven member; and a drive motor that changes the phase of the pair of opening/closing cam members by rotating the drive gear. , a control means for controlling the operation of the drive motor to rotate the drive gear so that the opening/closing period of each of the material transfer chucks is a predetermined period that is preset according to the axial length of the molded product to be forged; and a fixing means for fixing each pair of opening/closing cam members on the camshaft to the camshaft. (3) The fixing means includes cylinders fixed to the sides of each pair of opening/closing cam members on the camshaft, and within each of these cylinders, the fixing means rotates integrally with the camshaft, and is located at the axis of the camshaft. Claim 1 of the utility model registration claim 1 or Claim 1 of the utility model registration claim 1 is comprised of a piston that is slidably inserted in the direction and fastens each pair of cam members to the cam shaft. A material transfer device for a multi-stage heading molding machine according to item 2.
