PURPOSE: A device for manufacturing a yoke for a rivet is provided to successively separate and eject remnants after trimming and the complete yoke for the rivet, thereby omitting extra separation work subsequently. CONSTITUTION: A device for manufacturing a yoke(1) for a rivet comprises a transferring part(11), a correct position settling part(12), a trimming part(13), and an ejecting part(14). The transferring part grips the incomplete yoke, which is continuously fed after a first processing through a multi-stage forging work, and then horizontally transfers the yoke to the position for trimming. The correct position settling part moves up when the yoke is close to the position for trimming, and moves down when the yoke reaches the position for trimming, so that the yoke can be inserted into a correct position. The position for trimming, which is formed at the trimming part, is shaped into a groove so that a punching work and a forging work on the settled yoke can be simultaneously implemented. The trimming part simultaneously implements trimming work and a final molding, and then withdraws the complete yoke in the upper direction of the position for trimming. The ejecting part ejects the complete yoke and remnants after trimming. |
