Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a crossbeam of a laser cutting machine. Background Art

[0002] The cutting principle of the laser cutting machine 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. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material eventually forms a slit, thereby achieving the purpose of cutting. The laser cutting process replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, no limitation on cutting pattern, smooth incision, low processing cost, etc. It is widely used in the modern cutting field.

[0003] However, the laser cutting machine will produce a lot of smoke and dust during the cutting process, which contains harmful gases and particles, thereby polluting the surrounding working environment and causing harm to the health of the workers. The laser cutting machine beam commonly used at present is a hollow beam, which uses a hollow structure in the middle and sides to reduce the weight of the beam itself, and is supplemented by a slide rail on the outside for the cutting head to slide. Most of the beams use sliding wheels to assist in pushing or sliders to drive pushing. Therefore, the hollow part of the beam can be used to set a structure for dust collection and removal. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that a large amount of smoke and dust containing harmful gases and particles will be generated during the cutting process of the laser cutting machine, thereby polluting the surrounding working environment and causing harm to the health of the workers.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a laser cutting machine beam is provided, including a rectangular beam body, a circular through tube is arranged inside the beam body, a plurality of supporting ribs are fixedly connected to the outer wall of the circular through tube, one end of the supporting ribs is fixedly connected to the inner wall of the beam body, dust suction holes are arranged on both sides of the bottom of the beam body, the dust suction holes are connected to the circular through tube, dust suction fans are installed at the left and right end pipe openings of the circular through tube, and a smoke filter assembly is arranged on one side of the two dust suction fans.

[0006] Furthermore, the smoke filter assembly comprises a circular mounting frame mounted in the circular through pipe, an activated carbon filter is installed in the mounting frame, and a handle is fixedly welded on the horizontal outer side surface of the mounting frame.

[0007] Furthermore, the dust suction hole is a triangular three-dimensional hole in the vertical direction, and a metal filter screen for blocking large solid residue particles is installed at the hole end of the dust suction hole through screws.

[0008] Furthermore, eight supporting ribs are fixedly connected at equal angles on the outer wall of the circular through pipe.

[0009] Furthermore, the crossbeam body, the circular through tube and the supporting ribs are all made of high-strength aluminum alloy.

[0011] 1. The circular through-tube and dust suction hole embedded in the main body of the beam, together with the dust suction fan and smoke filter assembly installed at the pipe mouth, can efficiently purify the smoke generated during the cutting process, keep the working environment clean, and reduce the impact on the operator's health.

[0012] 2. The dust suction hole adopts a vertical triangular three-dimensional hole design, which, combined with the setting of the metal filter, can effectively block large solid residue particles, making cleaning and maintenance more convenient and quick.

[0013] 3. The supporting ribs inside the main body of the beam are fixedly connected to the inner wall, while the multiple supporting ribs on the outer wall of the circular through tube are fixedly connected at equal angles, together forming a stable and reliable supporting structure to ensure the stability of the beam and the accuracy of the cutting process.
