Laser cutting machine for cutting pipes

Abstract

The invention belongs to the technical field of laser cutting equipment, in particular to a laser cutting machine for cutting pipes. The laser cutting machine comprises a first main shaft, a first driving device and a cutting assembly, wherein the first driving device is used for driving the first main shaft to rotate; the first main shaft is provided with a cutting passage for allowing a pipe topenetrate through; the cutting assembly comprises a laser cutter and a rotary disc, the laser cutter is arranged at the front end of the first main shaft, and the rotary disc is rotationally arrangedat the outer side of the first main shaft by bypassing a rotary shaft which is connected with the first main shaft; the rotary shaft and the first main shaft are arranged in the same direction; the rotary disc is synchronously revolved with the first main shaft through the rotary shaft; the laser cutter is connected with a cable; one end of the cable is firstly wound on the part, at the front sideof the rotary disc, of the first main shaft, and the other end of the cable bypasses the rotary disc, and is wound at the part, at the back side of the rotary disc, of the first main shaft; the rotary disc can be rotated by self under the action of the cable so as to wind and adjust the cable. The laser cutting machine has the advantage that the breaking of the cable can be prevented in the cutting process; the rotation structure of the rotary disc is simple.

Description

technical field [0001] The invention belongs to the technical field of laser cutting equipment, and in particular relates to a laser cutting machine for cutting pipes. Background technique [0002] With the development of mechanical hardware, construction processing, sports equipment and other industries, the application of pipe processing is becoming more and more common. For the cutting of pipes, traditionally, some mechanical processing methods such as grinding wheel cutting are usually used to cut pipes.

[0002] With the development of mechanical hardware, construction processing, sports equipment and other industries, the application of pipe processing is becoming more and more common. For the cutting of pipes, traditionally, some mechanical processing methods such as grinding wheel cutting are usually used to cut pipes. Although This method is convenient to use, but its cutting efficiency and precision are low

With the rise of laser cutting technology, the current method of laser cutting pipes has been widely used in the processing industry. Generally, laser cutting equipment usually uses the method of rotating pipes and fixing the cutting head to cut, but this method The production efficiency is low and the material utilization rate is low. For this reason, people have developed a method in which the pipe does not rotate and the cutting head rotates to replace the traditional laser pipe cutting technology, and the pipe and the cutting head will be fed horizontally synchronously during cutting, thereby improving production. efficiency, but currently on the market using this cutting technology laser cutting equipment in the process of cutting head rotation, the optical fiber / electrical wire tube (cable) is easy to break, thus affecting the service life of the equipment, and correspondingly increasing the service life of the equipment Therefore, it is necessary to develop a laser cutting machine for cutting pipes that is not easy to break
