Split type mould structure for bent beam processing

Abstract

The invention discloses a split type mould structure for bent beam processing. The split type mould structure comprises a front plate, a rear plate group and a stretch-bending mould integrated betweenthe front plate and the rear plate group, wherein the front plate is in fastening connection to the stretch-bending mould through a bolt; the rear plate group is in fastening connection to the stretch-bending mould through the bolt; the rear plate group comprises two rear plates which are symmetrically arranged; a distance between the two rear plates is regulated to adapt to curved beams of different lengths; and the front plate, the rear plate group and the end part of the stretch-bending mould define a section slot. The split type mould structure defines a mould through the front plate, thestretch-bending mould and the rear plate bodies in a sectional mode, and the rear plates and the stretch-bending mould can be designed in a split mode to reduce mould weight to the greatest extent; and moreover, the split type mould structure can be adaptive to extending lengths of different front plate horizontal bodies to adapt to processing requirements of the curved beams of different lengths.

Description

technical field [0001] The invention relates to the technical field of rail vehicle bending beam processing, in particular to a split mold structure for bending beam processing. Background technique [0002] At this stage, rail vehicles, especially urban rail and railway rail vehicles, require large parts such as roof curved beams, middle curved beams, and side columns, and such parts are due to materials (carbon steel, stainless steel, aluminum alloy) ) are different, multiple sets of molds are required to cooperate during processing and molding. However, the curved beam mold used at this stage has the same radian and a cross-section distance from one set of molds. This kind of integral mold has the following disadvantages: [0003] 1. The production and processing of the overall mold is difficult and the production cost is high; [0004] 2. A set of tires can only process the middle curved beam with the same radian and one section distance, which has poor versatility and...

AI Technical Summary

Problems solved by technology

[0003] 1. The production and processing of the overall mold is difficult and the production cost is high;

[0004] 2. A set of tires can only process the middle curved beam with the same radian and one section distance, which has poor versatility and increases the time for workers to replace the tire, resulting in a decrease in production efficiency;

[0005] 3. The middle curved beam with the same radian and different section distances needs to make multiple sets of molds, which increases the cost of making molds
