Background
Laser pipe cutting systems are used to cut hollow pipes, which are typically made of metals such as stainless steel and carbon steel. Firstly, a laser cutting head emits a high-energy small-spot laser beam to be projected on the upper surface of the pipe to melt the pipe; then, high-pressure gas is blown out of the laser cutting head, the upper surface of the pipe is blown off by molten metal, a fine cut is formed, and the purpose of cutting is achieved; in the cutting process, the feeding shaft drives the laser cutting head to move along the radial direction of the pipe.
The blowing action in the cutting process can blow the molten metal liquid to the inner wall of the lower surface of the pipe; secondly, laser beams can be projected to the inner wall of the lower surface of the pipe through the cutting seams; this can affect the cutting effect. For this reason, machine tool manufacturers have designed slag-receiving devices to solve this problem.
The slag receiving device consists of a slag receiving rod and a slag receiving servo motor, wherein the slag receiving rod is made of metal. The working process is that before the laser cutting head emits laser, the slag-receiving servo motor controls the movement of the slag-receiving rods, and all the slag-receiving rods extend into the hollow pipe; therefore, most of the metal solution blown off from the upper surface of the pipe falls on the slag receiving rod, and the laser beam projected to the lower surface of the pipe from the slot also falls on the slag receiving rod; thus, the problem of improving the cutting effect is achieved.
