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 material transfer chuck by being driven in accordance with the rotation of each of these opening and closing cam members; The opening/closing cam members are individually phase-adjustable with respect to the camshaft so that the opening/closing period of the material transfer chuck can be adjusted, and the opening/closing cam members are fixed to the side surfaces of each pair of opening/closing cam members. a gear member that rotates integrally with the cam member; a drive gear that can be engaged with and detached from each of these gear members;
a rotation operating means for variably adjusting the opening/closing period of the material transfer chuck by rotating the drive gear to change the phase of the pair of opening/closing cam members;
Material transfer of a multi-stage heading forming machine, characterized in that fixing means are provided on the sides of each pair of opening/closing cam members on the camshaft to fix the cam members to the camshaft. Device. (2) It has a plurality of forging stations equipped with opposing dies and punches, and a plurality of material transfer chucks that reciprocate 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 multi-stage heading forming machine, which includes a camshaft that rotates in synchronization with the advancing and retracting movement of the punch, and a pair of opening/closing chucks provided on the camshaft corresponding to each of the material transfer chucks. and a plurality of driven members that open and close the respective material transfer chucks by being driven as the respective opening/closing cam members rotate, and the pair of opening/closing cam members are connected to a cam shaft. The opening/closing period of the chuck for material transfer can be adjusted by adjusting the phase of the chuck individually, and the chuck is fixed to the side surface of each pair of opening/closing cam members and rotates integrally with the cam member. a drive gear that can be engaged with and detached from each of these gear members;
A drive motor that changes the phase of the pair of opening/closing cam members by rotating the drive gear to variably adjust the opening/closing period of the material transfer chuck, and a drive motor that variably adjusts the opening/closing period of each of the material transfer chucks. a control means for controlling the operation of the drive motor to rotate the drive gear for a predetermined period that is preset according to the shaft length of the molded product; and a side of each pair of opening/closing cam members on the camshaft. 1. A material transfer device for a multi-stage heading forming machine, comprising fixing means disposed at each section for fixing the cam member to a cam shaft. (3) The fixing means includes a cylinder fixed to the side of each pair of opening/closing cam members on the camshaft, and a fixing means that rotates integrally with the camshaft within each cylinder, and that Claim 1 of the Utility Model Registration Claim or Claim 1 of the Utility Model Registration Claim, characterized in that the piston is slidably inserted in the axial direction and fastens each pair of cam members to the camshaft. A material transfer device for a multi-stage heading molding machine according to scope 2.
