In recent years, laser beam cutting has developed into a standard method in the manufacturing industry, primarily for cutting metals and non-metals. The laser cutting is to scan the material surface with high power density focused laser beam, heat the material to thousands or even tens of thousands of degrees centigrade in a very short time to melt or vaporize the material instantaneously, and blow the melted or vaporized material away from the cutting seam with high pressure gas, thereby achieving the purpose of cutting the material.
The laser cutting head generally comprises an optical fiber connector, a horizontal adjusting device, a focusing device, a protective lens device, an air guide device and a plurality of parts of the cutting head, wherein the parts are sequentially connected from top to bottom, and the axial centers of the parts are positioned on the same axis. The optical fiber connector is used for being connected with an optical fiber output unit of the laser generator and receiving laser. Because the received laser belongs to divergent light, the incident light angle needs to be adjusted by the horizontal adjusting device, and the divergent laser can be converted into parallel laser through the collimating lens arranged in the horizontal adjusting device for continuous use. The adjusted parallel laser passes through a focusing lens in the focusing device again to reach a cutting surface; in order to obtain the best cutting effect, a focusing knob on the focusing device can be rotated to adjust the focusing knob to the most appropriate focus according to the thickness of the plate. The protective glass device is used for isolating the external light path from the inside of the cutting head, so that the sealing of the light path is guaranteed, dust and impurities are prevented from entering the light path, and the service life of the whole optical fiber laser cutting head is prolonged. The gas guide device is used for assisting laser cutting in the laser cutting machining process. The cutting head is connected below the air guide device, the sensor is arranged on the cutting head, and the sensor joint is connected with the sensing signal processing circuit and the linear driving control circuit, so that the distance between the cutting head and the surface of the workpiece can be kept stable for a long time and reliably, and the optimal cutting quality is ensured.
