Claims

[Scope of Claim for Utility Model Registration] (1) The length of a long member such as a molding material having a substantially U-shaped cross section, which is pressed against the cam surface of a bending die and bent into a predetermined shape in the axial direction. In an axial bending device for a long member, a core metal that fits inside the U-shape of the long member is formed from a plurality of laminated hardened steel plate strips to correspond to the bending shape of the long member, and the core metal is 1. An axial bending device for a long member, characterized in that one end side is fixed to a bending die, and the other end side is provided along a cam surface of the bending die so as to be freely deformable. (2) Claim 1 of the utility model registration claim, in which the core bar is formed by laminating hardened steel strips whose outer layer is relatively thick and whose inner layer is relatively thin. Axial bending device for long members.
