Abstract
PURPOSE: To make working easy and improve working accuracy by subjecting the blank material mounted to a holder to various kinds of working while press-contacting the same with the inscribing surface of an inner ring type upper die.
CONSTITUTION: The gear 20 of a pressure driving member 17 mounted to a header shaft 16 meshes with the gear 2b of an inner ring type male die 2, whereby the die 2 is revolved at all times at a constant speed. The male die 2 slides to the holder 21 side by overcoming the pressing effect of a spring 11 holding a U-shaped inner ring holder 3 and presses the blank material 31 mounted to the holder 21 to the outside circumferential surface of the holder 21 with the part of its inscribing surface. This results in increased gripping force upon the blank material 31, and enables various. When the working by the inner ring type male die 2 is finished and the member 17 moves upward, the holder 3 is moved upward by the energyzing force of the spring 11, by which the male die 2 is released from the contact with the blank material 31.
