Washer forming unit and forming device

Abstract

This invention discloses a washer forming unit and its forming device, including a mounting plate. The mounting plate has a mounting groove at its top center and a through hole at its side center. Two support seats are bolted to the side of the mounting plate, and side mounting frames are bolted to the top of each support seat. The left sides of the two side mounting frames are bolted to the right sides of the mounting plate. The linkage and the movable seat facilitate movement of the movable seat, while a return spring allows the movable seat to automatically return to its original position. During the movement of the movable seat, the punch rapidly stamps the metal rod, causing the center of the metal rod to be recessed and the periphery to extend outwards. The punched metal remains on the metal rod, resulting in zero waste after the stamping process, thus significantly reducing the manufacturing cost of the washer.
