Improved production process of braking rail

Abstract

The invention relates to a novel production process of a braking rail in a car retarder of the railway industry. The process provides an improvement scheme aiming at the problems of complicated process, low product safety and the like existing in a traditional production process of the braking rail. The novel production process provided by the invention is characterized by utilizing a mould component to directly roll a steel billet into the braking rail. The steel billet is sequentially rolled by the mould component of the braking rail through the processes of knobbling, rough rolling, finish rolling and the like respectively for one-step forming. The novel process provided by the invention not only saves steel products, saves energy resources and reduces the labor capacity of a worker but also eliminates the phenomena of stress accumulation and metal fatigue of the braking rail produced by the traditional process and reduces the potential safety hazard of the braking rail in the braking process. The safety and the reliability of the running of railways are guaranteed.

Description

technical field [0001] The invention relates to an improved brake rail production process, in particular to a production process for directly rolling a steel billet into a brake rail by using a mold assembly. Background technique [0002] The brake rail is used in the hump equipment in the railway industry and is an important part of the vehicle reducer. When the slipped vehicle arrives, the driving device drives the brake rail to clamp the side of the vehicle wheel, and the vehicle is decelerated by friction with the side of the wheel. The brake rails used on the existing railways in my country are mainly processed from steel rails. However, with the expansion of the railway scale and the development of the railway industry, this process has gradually exposed its shortcomings: 1. The process is complicated and wastes raw materials. The steel billet is first rolled into a steel rail, and then the steel rail is processed into a brake rail, which is time-consuming and labor-i...

Problems solved by technology

The brake rails used on the existing railways in our country are mainly processed from steel rails, but with the expansion of the railway scale and the development of the railway industry, this process has gradually exposed its shortcomings: 1. The process is complicated and wastes raw materials

During the braking process, when subjected to a sudden increase in external force, the brake rail is prone to cracks or even breaks, which affects the braking effect. In severe cases, it will cause the truck compartment being marshalled to derail and overturn, resulting in a safety accident

[0003] Therefore, it is imminent to optimize and improve the brake rail production process and propose a new process that can solve the problems of high energy consumption and low product safety performance.
