Press processing method according to an embodiment of the present invention may further comprise a saving step (S70). Saving step (S70) may be included in the chamfering method.

In the saving step S70, the edges of the molded product P are finished by smoothing the edges of the molded product P. In the saving step S70, when the burr B is generated in the molded product P during chamfering, the burr B is removed from the molded product P.

Saving step (S70) is advantageously carried out before the forming step (S80).

In one embodiment of the present invention, the saving step (S70) is made through the saving device (30).

8 is a longitudinal cross-sectional view schematically showing an operating state of a saving step according to an embodiment of the present invention. Referring to FIG. 8, when the molded article P is seated on the third lower pad unit 31, a third As the upper pad unit 33 and the third saving unit 35 descend simultaneously, the third upper pad unit 33 presses the molded product P to fix the molded product P.

Subsequently, as the third saving unit 35 descends, the burr B is removed while passing through the chamfer processing portion of the molded product P.

The third elastic part 37 is elastically supported by connecting the third upper pad unit 33 and the third saving unit 35 to each other. Then, as the third saving unit 35 decreases, the third elastic portion 37 may improve the pressing force of the molded article P by the elastic force and prevent the flow of the molded article P.

Press processing method according to an embodiment of the present invention may further include a punching step (S90).

Punching step (S90) is subjected to the chamfering step (S30) or forming step (S80) and then punched the molded product (P) corresponding to the installation position of the molded product (P). Since the punching step S90 is operated with the same configuration as the piercing apparatus 10 described above, the description thereof will be omitted.

9 is a cross-sectional view illustrating a molded article that has been subjected to the punching step according to an embodiment of the present invention. Referring to FIG. 9, in one embodiment of the present invention, the punching step S90 is performed after the forming step S80. . The punching part P2 is formed in the molded product P that has undergone the punching step S90.
