The cylindrical workpiece 4 shown in (1) is concentrically arranged on the rotary table 32, and laser light is emitted from the laser processing head 33. When the ventilation window 3 is punched, the contour of the ventilation window 3 is cut out by rotating the rotary table 32 and the linear movement of the laser processing head 33. When the drip-proof ventilation window 2 is formed, the shear side 2a of the drip-proof ventilation window 2 is slit by the rotation of the rotary table 32 and the linear movement of the laser processing head 33, and then the workpiece 4 is bent.
And the respective bending punches 24 (relatively, the bending die 22 is located inside the work piece 4 and the bending punch 24 is located around the outer circumference of the work piece 4), and the upper side of the press machine The base is lowered to lower the pressing member 30. As a result, the slope 25 of the pressing member 30 comes into contact with the slope of the bending punch 24,
By further lowering the pressing member 30, the bending punch 24 moves in the direction of the bending die 22 against the spring force of the spring 27.

The work piece 4 is pinched by the outer molding portion 26 of the bending punch 24 and the drip-proof ventilation window 2 is formed. Then, when the upper base of the press is raised, the pressing member 30 rises and the bending punch 24 moves in the direction away from the bending die 22 by the spring force of the spring 27. (Return to the original position.) After that, the upper plate 22b of the bending die 22 is removed, and the workpiece 4 after molding, that is, the motor frame 1 shown in FIG. 5 is taken out. A drip-proof ventilation window 2 is formed in this.
