Profile multi-radian forming device

Abstract

The invention discloses a profile multi-radian forming device. The profile multi-radian forming device comprises an upper mounting shaft, a fixing plate, a mounting block, sliding guide pressing devices, upper edge molds, lower arc-shaped molds and an upper arc-shaped mold; the mounting shaft is fixed at the upper end of the mounting block; the sliding guide pressing devices are arranged at the two ends of the mounting block correspondingly, and the upper arc-shaped mold is arranged at the lower end of the mounting block; and the lower arc-shaped molds are installed on the fixing plate and correspond to the upper edge molds arranged at the bottoms of the sliding guide pressing devices correspondingly. The two ends of a profile are tightly pressed by springs and the upper edge molds on thesliding guide pressing devices and the lower arc-shaped molds, the upper arc-shaped mold presses downwards to enable the profile to stretch and bend to deformation, and the forming efficiency of the profile is high. The profile multi-radian forming device has the characteristics of being high in forming precision, convenient and fast to use and the like.

Description

technical field [0001] The invention relates to a press-bending forming device, in particular to a forming device with multiple radians of profiles. Background technique [0002] In the bending process, it is necessary to bend the sheet or pipe into a bow shape. Since the bow shape is formed by tangential bending of multiple arcs, in the existing processing, multiple sets of molds are required to bend a workpiece into a bow shape. It is formed by bending arcs one by one in multiple processes, the process is complicated and the efficiency is low. Moreover, during the bending process, since the material is not stretched, it will cause wrinkling and deformation at the bending point, resulting in scrapping of the material. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-curvature integrated forming device for sheet or pipe material with high processing efficiency and no wrinkle deformation at the bend.
