Problems solved by technology

[0003] The following problems exist in the bending process. First, the traditional stamping method is prone to cracking and deformation of the sheet metal, and it is impossible to obtain a U-shaped sheet metal part with a high degree of completion. Second, the sheet metal part has problems after bending. Springback at a large angle, unstable bending dimensions, and subsequent processing of sheet metal parts is required, resulting in low production efficiency

Abstract

The invention relates to a mold for bending and forming sheet metal U-shaped parts. The mold comprises a platform, bending devices, a traction apparatus, steel ropes and an extrusion forming device, wherein the bending devices are arranged at the upper end of the platform in a left-right symmetrical manner; a mounting wall is arranged at the rear end of the platform; the traction apparatus is arranged at the front end of the mounting wall; the steel ropes are connected between the traction apparatus and the bending devices; the platform is internally provided with a cavity; and the extrusion forming device is arranged on the inner wall of the lower end of the platform. According to the mold, by adopting a method of two-step forming of bending and then extruding, the U-shaped sheet metal parts obtained by bending do not rebound, the molding is perfect, subsequent procedures are reduced and the production efficiency is improved. An arranged driving motor drives the steel ropes to simultaneously pull sheets from two ends; by using the U-shaped mold, the sheets are preliminarily formed; and extrusion rolls extrude the formed sheets by adopting a rolling mode, so that the sheets are thoroughly formed, and the rebounding of the sheets is prevented.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a mold for bending and forming sheet metal U-shaped parts. Background technique [0002] Sheet metal is a comprehensive cold processing process for metal sheets, including shearing, punching / cutting / compositing, folding, welding, riveting, splicing and forming, etc. Its notable feature is that the thickness of the same part is consistent, and it is processed by the sheet metal industry. Products are called sheet metal parts. The sheet metal parts referred to by different industries are generally different, and they are mostly used for assembly; at present, with the increasing requirements for product diversity, U-shaped sheet metal parts are more and more used in products. More and more, the current industry mainly uses two methods of CNC bending to bend sheet metal parts and make them into U-shaped structures. [0003] The following problems exist in the bending ...
