Description

A laser cutting machine for fluid conduits of a plate-type radiator Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically a laser cutting machine for fluid conduits of plate heat sinks. Background Technology

[0002] A laser cutting machine uses a laser emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, 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 eventually formed in the material, thus achieving the purpose of cutting.

[0003] Laser cutting uses an invisible laser beam instead of a traditional mechanical blade, offering advantages such as high precision, fast cutting speed, no limitation on cutting patterns, automatic layout for material saving, smooth cuts, and low processing costs. It will gradually improve upon or replace traditional metal cutting equipment. The mechanical parts of the laser head do not contact the workpiece, preventing scratches on the workpiece surface during operation. Laser cutting is fast, producing smooth and flat cuts that generally require no further processing. The heat-affected zone is small, resulting in minimal deformation of the sheet metal. The cut is free of mechanical stress and shear burrs, offering high processing precision, good repeatability, and no damage to the material surface, making it economical and time-saving.

[0004] Existing technology CN220782614U discloses a tube laser cutting machine. The technical solution discloses that "this utility model discloses a tube laser cutting machine, including a connecting seat. A rotating seat is rotatably connected to the upper left side of the connecting seat. A driven frame is connected to the right side of the rotating seat. A turntable is rotatably connected to both the upper and lower right sides of the driven frame. A first gear ring assembly is provided on the inner side of the driven frame near the left side of the turntable. Two sets of bevel gear assemblies connected to the first gear ring assembly are provided on the upper and lower inner sides of the driven frame. The two sets of bevel gear assemblies are respectively connected to gear nut assemblies. This utility model relates to the field of tube laser cutting technology. In this tube laser cutting machine, during the tube cutting process, the air pump in the air extraction assembly is activated. The air pump extracts the dust generated by laser cutting through a conduit, an air extraction filter plate, a conveying shell, and a feeding plate. At the same time, the lower side of the pulley assembly drives the auger column to rotate. The rotating auger column transports the dust falling into the conveying shell, and finally the dust falls into the recycling box."

[0005] Although a tube laser cutting machine has been disclosed in the existing technology, there are still some shortcomings. Specifically, in the actual production operation, the cutting speed and accuracy are limited, and the adaptability to tubes of different thicknesses and materials is not strong, which makes it difficult to improve production efficiency and the work efficiency of operators, resulting in increased production costs.

[0031] The working principle of this utility model is as follows: During the operation of this laser cutting device, the guide tube 5 to be processed is placed on the roller 18. The control system controls the operation of the second motor 15, and the output shaft of the second motor 15 drives the chain to rotate. The rotation of the chain drives the roller 18 to rotate. Through the monitoring of the position sensor 19, the position sensor 19 transmits the information to the central system. The central system calculates and controls the roller 18 to transport the guide tube 5 to a suitable position. The control system controls the operation of the second cylinder 13, and the second cylinder 13 pushes the second piston rod 14 to move. The second piston rod 14 pushes the moving plate 17 to move.

Motor 6 drives lead screw 7 to rotate, and slide 4 moves towards the middle of lead screw 7 under the drive of lead screw 7. Cylinder 13 drives piston rod 14 to move, and piston rod 14 drives moving plate 17 to retract. Motor 15 drives rollers 18 to rotate, and rollers 18 drive guide tube 5 to move. When position sensor 19 detects that the other end of guide tube 5 has moved below slide 4, motor 15 stops operating, cylinder 13 drives piston rod 14 to move, and piston rod 14 drives moving plate 17 to move. Moving plate 17, in conjunction with fixed plate 16, moves guide tube 5... The device is fixed. The motor 6 drives the lead screw 7 to rotate. The slide 4 moves towards the moving plate 17 under the drive of the lead screw 7. When the cutting head 12 moves above the moving plate 17, the motor 6 stops, the cylinder 9 starts, and the cylinder 9 pushes the piston rod 10 to move. The piston rod 10 drives the laser generator 11 to move downward. The laser generator 11 starts and generates a strong laser beam that is emitted from the cutting head 12. The motor 6 drives the lead screw 7 to rotate, and the slide 4 moves towards the fixed plate 16 under the drive of the lead screw 7. The laser beam slowly cuts and polishes the guide tube 5. When the cutting head 12 moves above the fixed plate 16, the cutting work is completed.
