Abstract

PURPOSE: To form a lap joint with the flange part and cylindrical part being integral and having correlation of equal wall thickness or necessary wall thickness, by developing the cylindrical part of a perliminarily formed tube having a flange part, in the axial direction by means of a spinning device.
CONSTITUTION: After tightly holding a cylindrical part S1 of preliminarily formed product W1 forming a flange part (f) by pressing in a caliber 2a of an outside restraining pattern 2, the formed product W1 is rotated at high speed together with a turntable 1. In this state, by slowly raising the table 1, a spinning roll 8 rotatably borne on a supporting rod 4 vertically provided on a surface plate 3 is intruded into the cylindrical part S1 from above. As a result, the product is press-fed in the axial direction of the cylindrical part S1 gradually from a curved end part 8' for intrusion at the end of the roll 8. While reducing the inner wall thickness of the cylindrical part S1, it is developed as assisted by the fluidity of the metal material, so that a formed product W2 having a specified cylindrical part S2 may be formed.
