Bending forming structure of light-duty chain guide rail

Abstract

The invention discloses a bending forming structure of a light-duty chain guide rail. The bending forming structure comprises an upper cavity wall and a lower cavity wall which are arranged in parallel in a curve mode. An inner sidewall and an outer sidewall are arranged between the upper cavity wall and the lower cavity wall in parallel in a curve mode. The curves of the inner sidewall and the outer sidewall are identical to the curves of the upper cavity wall and the lower cavity wall. A guide bottom groove is formed in the middle of the lower cavity wall. The upper cavity wall and the lower cylinder wall are connected with the inner sidewall and the outer sidewall in a welded mode. A plurality of supporting pieces are welded between the upper cavity wall and the lower cavity wall and located outside the inner sidewall and the outer sidewall. The upper cavity wall and the lower cavity wall are provided with inner sidewall tenon holes and outer sidewall tenon holes. The inner sidewall and the outer sidewall are provided with inner sidewall tenons and outer sidewall tenons corresponding to the inner sidewall tenon holes and the outer sidewall tenon holes. The upper cavity wall and the lower cavity wall are provided with a plurality of supporting piece tenon holes. The supporting pieces are provided with tenons corresponding to the supporting piece tenon holes. By adopting the bending forming structure, the surface of the curved rail is more smooth and better in quality. The running condition at the curved rail is better. Molds do not need to be manufactured. The bending forming structure is lower in production cost and more suitable for small-scale production and customization.

Description

technical field [0001] The invention relates to spare parts of hanging clothing transmission line equipment, in particular to a bending forming structure of a light chain guide rail. Background technique [0002] The bending molding of the pulley guide rail of the existing clothing transmission line is obtained by drawing and bending the profile with a mold. Since bending with a mold is a process of extruding and extending metal, it is extremely difficult to ensure the accuracy and smoothness of the curved rail workpiece, and its surface quality will be uneven and deformation will occur. The poor operation of the mold affects the quality of the entire product, and the loss rate produced by the mold stretch bending forming process is high and there are many defective products. In addition, the bending radius of the workpiece is the fixed radius of the mold. In production, one mold can only produce one shape and size of the curved guide rail, which cannot be changed. If there...

Problems solved by technology

Since bending with a mold is a process of extruding and extending metal, it is extremely difficult to ensure the accuracy and smoothness of the curved rail workpiece, and its surface quality will be uneven and deformation will occur. The poor operation of the machine affects the quality of the entire product, and the loss rate of the mold stretch-bending process is high, and there are many defective products

In addition, the bending radius of the workpiece is the fixed radius of the mold. In production, one mold can only produce one shape and size of the curved guide rail, which cannot be changed. If there are multiple usage requirements, multiple molds need to be opened, resulting in waste of production costs. Therefore, the structure using the mold stretch bending process is not suitable for the production needs of small batch customization, and has the above-mentioned many defects
