A process for manufacturing a metal part (10), is described said part extending in a first direction (Y) and having a section comprising a central member (14) and at least a first side member (16) extending in a second direction. The process comprises the following steps: supply of a metal blank (30); removing material from the blank so as to form an intermediate part (32) comprising the central member (14), a junction zone (12) and at least first (116) and second (118) intermediate side members, with a space (34) between the first and second intermediate side members; and hot forming (104) the intermediate part, including spreading the first and second intermediate side members apart by inserting a first punch (212) between said members.

A center pillar reinforcement is produced satisfactorily by using a high-tensile material having a low ductility as a blank. The center pillar reinforcement is produced by performing a first step for producing a first intermediate formed product on which a body is partially formed by press-forming the blank using a first press-forming device for drawing, and a second step for pressing the first intermediate formed product by using a second press-forming device for bend-forming.

Disclosed is a manufacturing method that can suppress the occurrence of wrinkles and buckling deformation due to bending when bending and cross-sectioning are performed on a tube using a press die. The manufacturing method of the present disclosure includes applying pressure to a bent tube having a curved portion from the outside of the tube to the inside of the tube using a press die, thereby simultaneously performing cross-sectioning of the curved portion and bending of the curved portion to reduce the bend radius of the curved portion.

A seat frame manufacturing method including: performing extrusion molding of a metal material to form a workpiece material, which has a closed section shape or a solid section shape in which a plate piece continuous in an extrusion direction protrudes in a protruding direction from a portion thereof; and performing press working, the press working including bending a part of the plate piece of the workpiece material in an out-of-plane direction of the plate piece, which is different from the protruding direction of the plate piece, to obtain a finished product.
