Optical fiber laser cutting equipment

Abstract

The invention relates to the technical field of laser cutting equipment, and discloses an optical fiber laser cutting equipment. The optical fiber laser cutting equipment comprises a cutting head anda focusing lens, wherein the focusing lens is fixedly installed at the bottom of the cutting head, a connecting conical ring is fixedly installed at the bottom end of the cutting head, the bottom of the connecting conical ring is fixedly provided with arc-shaped baffles, and the outer side of the cutting head is in threaded connection with a fastening conical ring. According to the optical fiber laser cutting equipment, the diameters of cylindrical sections of cutting light penetrating through the inner diameters are changed by changing the inner diameters of the three arc-shaped baffles, thena to-be-machined part is erected, so that the cylindrical section of the cutting light is in contact with the workpiece, and the influence on the machining precision due to the taper of the cutting light can be reduced when the thicker workpiece is cut.

Description

technical field [0001] The invention relates to the technical field of laser cutting equipment, in particular to an optical fiber laser cutting equipment. Background technique [0002] Fiber laser cutting machine is a new type of laser cutting machine newly developed in the world. After the laser emitted from the laser is focused into a high-power-density laser beam through the focusing lens, the workpiece is cut. It has high precision and fast cutting. Not limited to cutting patterns, automatic typesetting saves materials, smooth cuts, low processing costs, etc. However, after the light is focused, the laser beam will be in the shape of a cone, so the cut gap is also a cone shape. In this case, for workpieces with a large thickness, an obvious taper will be formed, which will affect the processing accuracy. At the same time , during processing, in order to remove the burrs, a high-pressure gas will be ejected at the same time, which will cause the burrs to splash. May scr...
