Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting equipment, and in particular relates to a corrugated tube laser cutting machine. Background Art

[0002] 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, causing the workpiece to 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 is eventually cut, thereby achieving the purpose of cutting. With the development of today's society, the application scope of laser cutting machines is becoming more and more extensive, and more and more metal materials require laser cutting equipment to cut and process them. Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and telescopic direction, including metal bellows, metal hoses and other types. When cutting bellows, laser cutting machine is required.

[0003] The invention patent with publication number CN117564345B discloses an adjustable corrugated pipe cutting device, including a fixed frame; also including a cutting machine, a push rod II and a power assembly, etc.; the fixed frame is connected to the power assembly; the power assembly is connected to the cutting machine; the power assembly is connected to a plurality of push rods II. The invention uses tape to make roller I adhere to the surface of the corrugated pipe body. When the outer wall of the corrugated pipe body is concave and deformed, the roller I is pulled to move and the spring rod II is stretched. At this time, the roller I pulls the corrugated pipe body located in front of the cutting machine upward under the action of the rebound force of the spring rod II, thereby avoiding the problem of concave deformation of the outer wall of the corrugated pipe body.

[0004] However, in actual use, it is found that there are still some problems: it restores the deformed parts through an external pulling mechanism, and can only remedy the deformation after deformation, but cannot prevent deformation before deformation. At the same time, it does not have a structure for receiving the blanks after cutting. The corrugated pipe may still be deformed if it falls directly after cutting. Therefore, the existing device cannot meet the needs of actual use, so there is an urgent need for improved technology to solve the above problems. Summary of the invention

[0017] Beneficial effects: 1.

Under the action of gravity, even if the pipe body is not deformed during cutting and falls, it may be deformed. In the present invention, the pipe body does not fall directly after cutting the corrugated pipe. When the internal fixed structure shrinks and moves out, the external clamping structure clamps the cut pipe body to prevent it from falling. Then, it moves downward under the control of the cylinder, and is released after approaching the blanking plate to make it slowly slide from the blanking plate to the subsequent conveying structure, thereby avoiding the problem of deformation caused by impact force due to direct falling.

The internal fixing structure 51 and the external clamping structure 52 cooperate with each other to protect the inner and outer diameter surfaces of the bellows 4 at the same time to avoid the problem of concave deformation during the cutting process. Specifically, the internal fixing structure 51 is stretched out from the inside of the bellows, and the clamping block 515 is just in contact with the threaded recess on the inner diameter surface of the bellows 4. While the cutting part is tightened and protected, it is meshed with the inner diameter surface thread of the bellows 4, so it does not interfere with the cutting rotation of the bellows 4. When the laser head 67 cuts the corrugated tube 4, the fitting point of the clamping block 515 can be adjusted to the position of the inner wall of the threaded tube 4 close to the tangent according to actual needs, so as to support the cutting part and avoid the problem of depression on the inner diameter surface when the corrugated tube is cut.
