A device that can automatically adjust the preheating position of the cutting gun

Abstract

The invention relates to a device capable of automatically adjusting the preheating position of a cutting torch, which includes a motor, a stopper is installed on the output shaft of the motor, a counting proximity switch is installed on the reducer, the other end of the output shaft of the motor is connected with the reducer, and the cutting trolley machine There is a distance x between the original position of the cutting torch and the edge of the slab to be cut. The whole device is controlled by the PLC controller. It solves the problem that the edge of the slab does not coincide with the preheating position of the cutting torch due to uneven cooling and other reasons, and the preheating of the slab cannot be completed, and the in-situ proximity switch of the cutting torch must be frequently adjusted online. The feature of remote automatic adjustment of the original position of the cutting gun.

Description

technical field [0001] The invention belongs to the technical field of continuous casting flame cutting machine equipment, and relates to the design and application of a device capable of automatically adjusting the preheating position of a cutting torch, which is convenient for adjusting the preheating position of a cutting torch. Background technique [0002] The cutting gun of the billet flame cutting machine of the continuous casting machine is generally driven by a motor. After the billet is cut, the cutting gun returns to a fixed position (the edge of the billet) and waits for the next cutting. This position is called the original position of the gun, that is, In the traditional design, the original position of the cutting torch, the edge of the slab and the preheating position coincide. A proximity switch is installed on the original position of the gun. When the cutting gun returns to the original position of the gun and touches the proximity switch, the proximity sw...

AI Technical Summary

Problems solved by technology

When adjusting the original position of the gun, the operator is in the harsh environment of high temperature radiation and cutting steel spatter. The adjustment is difficult, and the safety of the operator cannot be guaranteed. The number of times to adjust the original position of the gun in each work shift reaches 7 -8 times with a lot of work
