開け＃！５図の状態となる。The process of molding the component W using the press die configured as described above will be explained. The flat flange portion Wla and the cylindrical portion F1b of the intermediate molded body W1 of the part W are formed by drawing the cylindrical portion F11. is made in several steps, and after molding, the bottom is punched out in a hole punching step, and the bottom periphery is trimmed Y, which is a well-known pressing process. When this intermediate formed body W1 is sent to the receiving position of the conveyor H by a conveyor, chute, or transfer mechanism, the conveyor H grips the flange F1a of the intermediate formed body W1 horizontally from both sides, and is moved horizontally by the transfer mechanism. Then, the conveyor H passes through the two-sided cutout 8b, the cylindrical portion F1b passes through the side notch 8c of the knockout 8, and is conveyed to a position coaxial with the die 3. The conveyor H opens and the intermediate formed body F1
is placed on the upper surface 8a of the knockout 8. Transport tool H
When the ram is retracted, the upper table 12 integrated with the ram is gradually lowered by rotation of a cam (not shown). First stripper 11
The lower end of the intermediate molded body F1 presses the flange W1a, and the knockout 8 is pushed down against the force of the spring 9, and the flange W11L
is pressed against the upper surface 6b of the die 6 at the lower end of the strip 11. At this point, the drive rod 5 is pushed up against the force of the spring 7 due to the rotation of the cam 6, and the first bunch 4 rises until the upper end 4d is inserted into the cylindrical portion F1b of the intermediate formed body F1. The shearing blades on each inclined surface (b) shear the cylindrical portion (Fit) in the vertical direction, resulting in the state shown in FIG. 4. The cylindrical portion F11) of the intermediate molded body W1 is sheared on both sides of the portion that will become the tooth tip Fb of the component W, and the cut portion is pushed outward. As the ram continues to descend, the second bunch 14 descends together with the punch holder 13 integrated with the upper stand 12, and the end of the small diameter portion 14d at the lower end contacts the first bunch 4 and pushes it down, and the small diameter portion 14a becomes the cylindrical portion of the intermediate formed body W1. The base part Fd of the cylindrical part W1b is inserted into the rib and the punching blade 14a is sheared in FIG. Punch out the bottom of the tooth to make a persimmon petal-shaped hole #! The state shown in Figure 5 will be reached.

and is discharged from the discharge port 3g of the die 6 by the pressurized air sent out from the side. When the ram rises, the stripper 11 and second bunch 14 also rise, knocking out 8.
The force of spring 9 pushes the formed part FE into the position shown in FIG. The conveyor I moves forward and grips the flange rta (E- from the side) and sends it to the next process, and transfers it to the next new intermediate molded product u.
71 is conveyed onto the knockout 8.

In this case, the wall thickness of the hole 3a of the die is just the thickness on which the intermediate molded body is placed, and the knockout is partially modified so as to push up the lower end of the outer circumferential line.

有するものである。Effects As detailed above, the present invention has a die having petal-shaped holes 3, with a first punch for shearing the cylindrical portion disposed below the die, and a second punch for punching the base portion disposed above the die. Therefore, in small parts, the bent portion of the internal teeth can be long compared to the size of the hole, and the length can be selected with a considerable degree of freedom. In addition, since the bent part is curved and forms part of the circumference, it fits well when fitting with other parts or winding wire.
After shearing the end of the tooth from below with a punch, #! Since the punching process is performed using two bunches, there is no burr at the tip of the tooth end, so secondary processing such as barrel polishing is not required.
