Claims

[Scope of utility model registration request]

A plurality of forging stations equipped with opposing dies and punches, a plurality of material transfer chucks that reciprocate in the direction in which these forging stations are lined up and sequentially transfer materials to each forging station, and forward and backward movement of the punches. A camshaft that rotates in synchronization with
A pair of cam members are provided on the cam shaft for each of the material transfer chucks and change the opening/closing timing of the chucks by changing their mutual phases, and a pair of cam members that are interlocked with the rotation of each of these cam members. The material transfer device for a multi-stage heading forming machine is provided with a plurality of driven members for opening and closing each of the material transfer chucks, wherein each of the pair of cam members is configured to rotate integrally with the cam member. A fastening means for fastening the attached worm wheel and the pair of cam members to each other and fixing each cam member to the cam shaft; a releasing means for releasing the fastening and fixing; A phase adjustment unit has a unit mounting portion provided at a nearby position, a pair of worms meshing with the worm wheels, and a rotation means for rotating these worms. A material transfer device for a multi-stage heading forming machine, characterized in that it can be attached so as to mesh with a wheel.
