Description

Technical Field

[0001] The utility model relates to the field of numerical control flame cutting machines, and particularly relates to a slag blowing device for a numerical control flame cutting machine and a numerical control flame cutting machine. Background Art

[0002] A numerical control flame cutting machine is a cutting device that uses a digital program to drive the movement of a machine tool, is equipped with a flame cutting system, and uses a numerical control system to control the on / off of the flame cutting system to cut metal materials such as steel plates. The numerical control flame cutting machine has the ability to cut thick carbon steel, and the cutting cost is relatively low. However, there are problems such as large cutting deformation, low cutting accuracy, low cutting speed, long cutting preheating time and piercing time, and it is difficult to meet the needs of fully automated operation. Therefore, the application scenarios of numerical control flame cutting machines are mainly limited to the cutting of carbon steel and thick plates.

Among them, the electrical part generally includes a numerical control system, a motor drive system, a torch lifting system, a height adjustment system, etc. The mechanical part generally includes a cross beam, a guide rail installed on the cross beam, a lifting frame installed on the guide rail, and a torch installed on the lifting frame. The lifting frame moves along the length direction of the cross beam through the guide rail and can drive the torch to move up and down. However, in the actual use process, it is found that a large amount of cutting slag and spatter will be generated when the torch cuts and pierces. The cutting slag and spatter will splash into the nozzle area of the torch, resulting in nozzle blockage and affecting the normal operation of the numerical control flame cutting machine.
