Laser cutting machine for separating and processing metal pipe fittings

Abstract

The invention relates to a laser cutting machine for separate processing of metal pipe fittings, which comprises a base, a feeding and fixing unit and a cutting and unloading unit. The upper left side of the base is provided with a feeding and fixing unit, and the right side of the upper end of the base is provided with a cutting and unloading unit. The present invention makes the laser cutting head rest on the upper end of the metal pipe by feeding the laser cutting head intermittently, completes the cutting of a single pipe through the rotation of the metal pipe, and then cuts a plurality of metal pipes in turn by intermittently moving, thereby It solves the problem of low efficiency of pipe laser cutting equipment for pipe cutting; the invention realizes the same motor to drive multiple metal pipes to rotate through forward and reverse through the mechanical structure through the design concept of one machine with multiple functions, and the clamping mechanism Clamping and fixing of metal pipes.

Description

technical field [0001] The invention belongs to the technical field of pipe material processing, in particular to a laser cutting machine for separating and processing metal pipe fittings. Background technique [0002] The material to be cut is irradiated with a high power density laser beam, so that the material is quickly heated to the vaporization temperature, and evaporates to form a hole. As the beam moves to the material, the hole continuously forms a narrow slit to complete the cutting of the material. Due to the small laser spot, high energy density and fast cutting speed, laser cutting can obtain better cutting quality. The laser cutting incision is narrow, the two sides of the slit are parallel and perpendicular to the surface, and the dimensional accuracy of the parts to be cut is high; the cutting surface is smooth and beautiful, and the surface roughness is only tens of microns, and even laser cutting can be used as the last process without mechanical processing...

AI Technical Summary

Problems solved by technology

[0003] The following problems often exist in the process of laser cutting metal pipes: 1. The existing pipe laser cutting equipment often cuts off the openings on the outer wall of the pipe after close processing, and only processes one pipe at the same time, so that when the pipe is only When it needs to be cut, the laser cutting efficiency of a single pipe is too low; 2. Since the pipe cutting requires the pipe to rotate, the clamping mechanism for the pipe needs to rotate, but it is difficult to solve how to control multiple self-rotating clamping mechanisms during multi-station cutting open and close
