Problems solved by technology

[0005] However, the process of making products from materials in the stretch bending process requires many processes, so it has the disadvantage of low productivity, while in the roll bending process, since the material is not deformed to the material yield point (yield point), it will rebound and cannot get the desired curvature

Abstract

A bending press system is disclosed. The bending press system may include: at least one guide post; a slide plate mounted at a slider so as to be slidable upwardly or downwardly along the guide post; a bending die including a lower die having an upper surface and an upper die having a lower surface corresponding to the upper surface of the lower die and mounted on a lower surface of the slide plate, and adapted to bend an object supplied between the lower die and the upper die to have a predetermined curvature; and a pair of clamping means mounted respectively at both sides of the bending die corresponding to the bending die and adapted to clamp both end portions of the object.

Description

Technical field: [0001] The invention relates to a bending device, in particular to a bending device for pressing and forming the extruded pipe so as to have a certain curvature in the state of clamping both ends of the extruded pipe. Background technique: [0002] Generally, for a bumper beam for a vehicle formed into a tube by extrusion, in order to make it have a certain curvature in the length direction, a stretch bending process or a roll bending process is generally used. [0003] As far as the stretch bending process is concerned, the two ends of the metal pipe are fixed so that the center of the metal pipe contacts a mold with a certain curvature, and then force is applied to the mold at the two ends of the metal pipe so that Metal tubing has a certain curvature. [0004] Moreover, in terms of the roll bending process, if a metal pipe is put into a plurality of bending rolls arranged and rotated with a certain curvature, the metal pipe will have a certain curvature ...
