Bending tool of rail wagon uncoupling rod

Abstract

The invention discloses a bending tool of a rail wagon uncoupling rod. The bending tool comprises a base plate, a location plate assembly and at least two groups of bending pin assemblies, wherein the location plate assembly is used for fixing the end part of a lifting rod, the bending pin assemblies are used for forming a bending part of the middle part of the lifting rod, the location plate assembly and the bending pin assemblies are respectively arranged on the base plate in a sliding manner, each bending pin assembly comprises a cross beam and a bending pin, the cross beams are connected with the base plate, the bending pins are arranged on the cross beams in the sliding manner, the location plate assembly and the cross beams slide horizontally relative to the base plate, and the bending pins slide vertically relative to the cross beams. According to the bending tool disclosed by the invention, by aiming to uncoupling rods of different shapes, the different positions of the location plate assembly and the bending pin assemblies on the base plate are regulated, so that the manufacturing of the uncoupling rods of the different shapes through a set of tools is realized, the universality of the tool is largely improved, the manufacturing cost of the tool is reduced and the manufacturing period is shortened.

Description

Technical field [0001] The invention belongs to the field of railway freight car manufacturing, and particularly relates to a bending tool for a rail freight car coupler lifting rod. Background technique [0002] At present, the coupler lifting rods used in railway freight cars are restricted by the conditions of the vehicle, and have different shapes. One type of railway freight car is designed with two different shapes of coupler lifting rods. Correspondingly, two sets of tooling must be designed and manufactured for production. The manufacturing cost is high and the manufacturing cycle is long. Summary of the invention [0003] The purpose of the present invention is to provide a bending tool that can realize a set of tooling to manufacture coupler lifting rods of different shapes in view of the above existing problems. [0004] The technical scheme of the present invention is realized as follows: a bending tool for the lifting rod of a railway freight car coupler, which is char...
