Laser cutting machine and its slag removal method

Abstract

The invention discloses a laser cutting machine, which comprises a fixed chuck, a laser cutting head located on the right side of the fixed chuck, a movable chuck located on the left side of the fixed chuck, a slag remover and an air pump located on the right side of the laser cutting head Device; the slag remover is provided with an inner cavity, an air suction inlet and an air extraction pipe, the air extraction inlet is located on the left side of the slag remover and communicates with the inner cavity, one end of the air extraction pipe is connected with the inner cavity, and the other end is connected with the air extraction device. In addition, a method for removing slag is provided, which includes the following steps: start the suction device to pump air into the inner cavity of the slag remover; drive the slag remover to move relative to the metal pipe, so that the suction inlet of the slag remover and one end of the metal pipe Connected, the lumen of the metal tube is pumped. Compared with the method of inserting the chip removal pipe into the metal pipe for chip removal, the present invention uses the cut metal pipe as a part of the slag remover. The inner diameter of the metal pipe is larger than the inner diameter of the chip removal pipe. When the metal pipe is vacuumed, the metal The lumen of the tube is relatively easy to achieve the ideal vacuum degree, which can improve the effect of debris removal.

Description

technical field [0001] The invention relates to the technical field of pipe cutting machines, in particular to a laser cutting machine and a slag removal method thereof. Background technique [0002] During the laser cutting process, a large amount of metal slag will be blown into the metal tube, which will adhere to the inner wall of the metal tube and form burrs after cooling, which will seriously affect the smoothness of the wall surface of the tube. The pipe needs to be deburred, which undoubtedly reduces the efficiency of the pipe production. [0003] At present, in order to complete the slag removal work, a chip removal locator is often installed on the laser cutting machine. The chip removal locator mainly includes a plug, a chip removal pipe and a driving device. The through hole corresponding to the pipe, the diameter of the through hole is smaller than the inner diameter of the metal pipe; the outer diameter of the chip removal pipe is smaller than the diameter of...

AI Technical Summary

Problems solved by technology

[0005] However, since the outer diameter of the chip removal pipe must be smaller than the inner diameter of the metal pipe, the pipe diameter is small, the air flow rate is fast, and the resistance is large (that is, the pressure drop is large), and it is not easy to achieve the ideal vacuum degree in the chip removal pipe. Chips have to be sucked into the chip removal pipe through the small gap at the top of the chip removal pipe, therefore, the chip removal effect of the chip removal positioner is mediocre and the processing quality of the pipe is reduced
