摘要:
A hemming processing device (1), comprising a holder unit (2), a drag (3) for installing the holder unit (2) thereon, and a cope (4) vertically movably installed on the drag (3). The holder unit (2) further comprises a base (5) fixed to the drag (3) with bolts, a machining tool holder (7) rotatably supported on the base (5) so that a hemming punch (6) can be disposed at a non-machining position and a machining position, and an elastic means (8) elastically energizing the machining tool holder (7) so that the hemming punch (6) can be disposed at the non-machining position.
