Claims

[Claims for Utility Model Registration] A blank holder 6 that presses the outer periphery of a plate-shaped blank W having a slit 30 or a hole 22 formed in the center from one side; A die 9 is press-contacted from the side surface and has an inner circumferential surface 12 for drawing on the inner circumferential side, and a die 9 is press-contacted from the blank holder 6 side near the periphery of the slit 30 or hole 22 formed in the blank material W, and has an inner circumferential surface 12 for drawing on the inner circumferential side. a punch 5 having an outer circumferential surface 11 for drawing, and installed so as to be movable toward and away from the die 9; and the punch 5 moves toward and away from the die 9 to form a blank The material W is drawn, and the upper flange portion 25 is formed at the portion of the blank material W that the top of the punch 5 comes into pressure contact with, and the outer peripheral surface 11 for drawing formed on the punch 5 and the die 9 are formed. When forming the cylindrical portion 13 in a portion interposed between the drawing inner circumferential surface 12 and forming the lower flange portion 26 in the portion sandwiched between the die 9 and the blank holder 6, At a predetermined close position of the punch 5 to the die 9, the blank material W is bent around the slit 30 or the hole 22 formed in the center thereof, and the bent portion 27 is inserted between the punch 5 and the punch 5. A flanged cylindrical manufacturing apparatus comprising a bending means 17 mounted so as to be sandwiched between the flanged cylinder body.
