A laser cutting machine

Abstract

The invention belongs to the technical field of laser cutting, and specifically relates to a laser cutting machine, which includes a base, a frame and a controller; end and the surface of the motor shaft; the surface of the shaft is uniformly and fixedly sleeved with the first spring, and the inner diameter of the first spring decreases successively from left to right; a laser generator is fixedly connected to the inner wall of the top of the frame; the laser generator The right side of the dry ice maker is provided with a dry ice maker; the lower surface of the dry ice maker is provided with evenly arranged high-pressure nozzles; the inside of the sealed barrel is slidingly connected with an extrusion plate; the inner wall of the protective cover is evenly arranged with air ports; the first Convex teeth are evenly arranged on the surface of the spring wire of a spring; sand particles are attached to the surface of the protruding teeth; an air collection chamber is fixedly connected to the top of the frame; the air collection chamber communicates with the dry ice maker; the invention has the advantages of simple operation , The product has the characteristics of high cutting efficiency, uniform and thorough cooling, and long service life.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, in particular to a laser cutting machine. Background technique [0002] Laser cutting is to focus the laser emitted by the laser into a laser beam with high power density through the optical path system. The laser beam is irradiated on the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal. purpose of cutting. [0003] There are also some technical solutions for laser cutting machines in the prior art. For example, a Chinese patent with an application number of 2014103672566 discloses a laser cutting machine, including: a laser assembly, which is placed under the laser assembly and used to transport the product to be cut. The transfer table, the protective cover for fixing the laser component and placed on the laser component, and the dry ice coo...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, the product cannot be effectively cooled during transportation, the friction is too large, the product transportation speed is slow, the light source cannot be effectively dissipated, long-term use is easy to cause damage, and when a single nozzle is sprayed with dry ice, the dry ice cannot be used. Spraying the surface of the product evenly causes the problem of uneven cooling. A laser cutting machine proposed by the present invention
