Technical Field
[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a laser cutting device that can effectively remove cutting residue. Background Technology
[0002] A laser cutting machine focuses a laser beam emitted from a laser source into a high-power-density beam through an optical path system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, 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, a kerf is formed in the material, achieving the cutting purpose. Laser cutting uses an invisible beam instead of a traditional mechanical blade, offering advantages such as high precision, fast cutting speed, no limitation on cutting patterns, automatic layout to save material, smooth cuts, and low processing costs. It is gradually improving upon or replacing traditional metal cutting equipment. The mechanical parts of the laser cutter head do not contact the workpiece, so they will not scratch the workpiece surface during operation; laser cutting speed is fast, the cut is smooth and flat, and generally no further processing is required; the heat-affected zone is small, the deformation of the sheet metal is small, and the kerf is narrow (0.1mm~0.3mm); there is no mechanical stress on the cut and no shearing burrs; the processing accuracy is high, the repeatability is good, and it does not damage the material surface; CNC programming can process any planar shape, and it can cut large sheets of sheet metal without the need for molds, which is economical and time-saving.
[0003] However, existing laser cutting machines are prone to leaving cutting waste residue during the cutting of pipes and shafts due to the characteristics of the materials themselves. The residue left on the metal surface after laser cutting is called molten metal and slag. If the slag generated during the cutting process is not cleaned in time, it will affect the smoothness and precision of the cut surface, and may even cause the cut parts to stick together, which will affect the cutting quality, equipment life and safety.

This effectively ensures the cleanliness of the cut, ensures the cleanliness and flatness of the cut surface, improves the cutting quality, provides a good foundation for subsequent processing, and makes the pipe flatter, with high cutting precision, good cutting effect, and strong practicality.

[0037] Specifically, the base 100 has multiple mounting holes 101 recessed around its perimeter to facilitate the installation and fixation of the base.
[0038] Specifically, the working principle and process of this utility model are as follows:
[0039] First, the pipe 600 is inserted into the V-shaped opening groove. Turning the handle drives the first clamping plate 401 and the second clamping plate 402 to move towards the center simultaneously until the pipe is firmly clamped and fixed. Then, the drive motor and the first screw drive the gear ring to rotate uniformly in the circumferential direction. At this time, the gear ring drives the laser cutting head to rotate, achieving 360° rotational cutting of the pipe. Simultaneously, the residue suction nozzle abuts against the outer circumferential wall of the pipe cut. The gear ring drives the residue suction nozzle to rotate, and under the action of the scraper, the residue adhering to the surface of the cut is scraped off. The residue falls into the suction nozzle. Because the inside of the suction nozzle is under negative pressure, the scraped residue is quickly sucked away by the nozzle and enters the waste recycling bin, thus effectively ensuring the cleanliness of the cut, ensuring the cleanliness and flatness of the cut surface, improving cutting quality, and providing a good foundation for subsequent processing. This results in a flatter pipe during cutting, high cutting precision, good cutting effect, effectively ensuring cutting quality, and strong practicality.
