Laser cutting device capable of efficiently cleaning dust

Abstract

The laser cutting device comprises a laser cutting machine body, a bottom groove is formed in the inner side of the bottom of the laser cutting machine body, a horizontal rod is fixedly installed at the bottom of the side wall of the bottom groove, and an adjusting threaded rod is installed on the portion, above the horizontal rod, of the side wall of the bottom groove in a penetrating mode through a bearing pedestal; dust suppression mechanisms are arranged on the tops of the first guide plate and the second guide plate correspondingly and penetrate through side movable windows, the side movable windows are formed in the side wall of the bottom of the laser cutting machine body, and meanwhile the dust suppression mechanisms are connected with a water supply pipe. According to the laser cutting device capable of efficiently cleaning dust, novel structural design is adopted, metal particles and powder moving to the position below a laser beam cutting position can be effectively adsorbed and discharged, a sawtooth structure for supporting a workpiece can be independently replaced, the cost of overall replacement of a supporting structure is reduced, and the working efficiency is improved. And the stability of the workpiece in the machining process is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, and in particular relates to a laser cutting device capable of efficiently cleaning dust. Background technique [0002] Laser cutting machine is a kind of automatic cutting equipment. The laser cutting machine focuses the laser light emitted from the laser device into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. The movement of the relative position between the beam and the workpiece finally makes the material form a slit, so as to achieve the purpose of cutting. When the laser beam irradiates the surface of the workpiece, the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal, reducing the residue on the surface of the workpiece. Chips of the workpiece. [0003] In the existing laser cutting machine, the high-pressure ...

AI Technical Summary

Problems solved by technology

[0003] In the existing laser cutting machine, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal, and the metal particles and powders that cool down and become solid remain in the laser cutting machine, which cannot be discharged, and the laser cutting machine needs to be disassembled regularly It is troublesome to clean the remaining metal particles and powder, and the laser cutting machine uses a steel sheet with a sawtooth structure on the top to support the workpiece. While ensuring the support effect, it reduces the contact area with the workpiece and avoids laser cutting. The beam cuts the traditional flat support structure, but after the laser cutting machine works for a period of time, the contact position between the top of the sawtooth structure and the workpiece will still be melted. In order to control the cost, it is generally wait until the top of more sawtooth structures are melted before cutting the steel sheet However, when the tops of multiple sawtooth structures are melted, the steel sheet cannot provide stable support for the workpiece, and the workpiece is easy to shake during processing. It should be noted that the above content belongs to the technical cognition category of the inventor and is not necessarily prior art
