Flame cutting tool

Abstract

The invention provides a flame cutting tool. The flame cutting tool comprises a frame part, an air cutting part, a casting blank and a control part; the frame part comprises a bracket, a power part, aworking platform and a clamping part; the power part penetrates through the left and right ends of the bracket, and is fixedly connected with the bracket; the working platform is vertically arranged,is positioned at the right end of the bracket, and is fixedly connected with the power part; and the clamping part is fixedly mounted on the right end surface of the working platform. The flame cutting tool adopts a cooperating mode of the frame part, the air cutting part and the casting blank to realize automatic cutting of the casting blank; and through vertical arrangement of the working platform, an unfixed end of the casting blank automatically falls under the effect of gravity after cutting to prevent bonding of a fixed end and the unfixed end through high cutting temperature, so that the separation auxiliary work after cutting is reduced, the cutting efficiency of the casting blank is improved, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of flame cutting, in particular to a tool for flame cutting. Background technique [0002] In today's era, trains, automobiles, urban rails, etc. have been called irreplaceable modern tools for human land passenger and cargo transportation without exception, and play a pivotal role in social life. Human beings have higher and higher requirements for vehicles. Such as high speed, heavy load, safety and reliability, comfortable ride, etc. With the rapid development of China's high-speed railway, its various performance requirements have also been correspondingly improved, especially stricter requirements for braking performance. The speed of the train is in the third power relationship. The emergency braking of the train is mainly realized by the friction of the brake disc and the friction pair of the brake pad in the vehicle braking system. The conventional brake pad is made of cast steel. The speed and dire...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the following problems in the prior art, the boss cutting of the existing brake pad technology is usually cut manually, the cutting workload is relatively large, the cutting surface is not smooth, the cutting quality is not good, and because the casting blank is cast after tempering The temperature is more than 200 degrees Celsius. The working environment is not good when workers cut, and the risk is relatively high, which seriously affects the cutting work efficiency.
