Laser cutting device partition dust removal device

Abstract

The invention discloses a laser cutting device partition dust removal device. The dust removal device comprises a cutting machine shell, a laser cutting head and a air blowing cover; the laser cuttinghead is install at the inner top end of the cutting machine shell, and the air blowing cover is fixedly connected with the inner wall of the cutting machine shell; a tapered aggregate slot is installed at the inner bottom end of the cutting machine shell, and the bottom end of the tapered aggregate slot is connected with a discharging pipe in a conducting mode; a cutting worktable and a cleaningassembly are installed at the opening end of the tapered aggregate slot separately, and the cleaning assembly comprises a linear sliding table, a cleaning rod and a wire brush separately; the cleaningrod is installed in the linear sliding table, and the exterior of the cleaning rod is wrapped by the wire brush; and a tail gas guide assembly is inserted into the top of the cutting machine shell ina connected mode, and one side of the tail gas guide assembly is connected with a tail gas purifying assembly through a induced draft fan in the conducting mode. According to the dust removal device,a part of dust waste residue and tail gas are directionally extracted, purified and filtered, and the surface of a workpiece is cleaned through the cleaning assembly; and the cleanliness and comfortlevel of the working environment are improved.

Description

technical field [0001] The invention relates to the technical field of laser cutting machines, in particular to a partition dust removal device for laser cutting machines. Background technique [0002] Laser cutting is to focus the laser emitted from the laser 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, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. With the movement of the relative position of the beam and the workpiece, the material will eventually form a slit, so as to achieve the purpose of cutting. [0003] Laser cutting process replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting saves materials, smooth incision, and low processing cost. It...

Problems solved by technology

[0006] The object of the present invention is to provide a kind of laser cutting machine partition dedusting device, to solve the existing laser cutting machine proposed in the above-mentioned background technology when in use, during the process of laser cutting operation of the laser cutting machine, accompanied by particle waste residue, Dust waste and irritating exhaust gas are generated, some particle waste will automatically fall under the action of its own gravity and gas pressure, dust and waste slag will be suspended around the cutting position, and irritating exhaust gas will fly with the air In the process, the dust removal operation will be performed on the surface of the cutting workpiece, but the dust removal effect is not good, and the dust removal cannot be effectively partitioned, which reduces the cleanliness and comfort of the working environment.
