Abstract: A bending die used in the apparatus for manufacturing the automotive suspension arm to bend a rod-like raw material and produce a bent material includes a lower bending die including a mounting portion for mounting thereon the rod-like raw material and an upper bending die including a pressing portion for vertically pressing the rod-like raw material mounted on the lower bending die. The mounting portion and the pressing portion include a lower die contact portion and an upper die contact portion each formed into a shape along the bent shape of the bent material to come in contact with the bent material. The lower die contact portion includes, in the middle portion thereof, a groove portion formed to have a size which allows a moving means to grip the bent material in non-contact relation with the bent material.

Abstract: There are provided a bending die to be used in an apparatus and method for manufacturing an automotive suspension arm to allow the manufacturing apparatus to have a simple and low-cost structure and a reduced installation area and perform automated manufacturing, and the apparatus and method for manufacturing the automotive suspension arm using the bending die.
