Description

Technical Field

[0001] This invention relates to the field of thin-walled pipe laser cutting technology, and in particular to a multifunctional thin-walled pipe product laser cutting device. Background Technology

[0002] Thin-walled stainless steel pipes are widely used in various industrial and commercial fields, especially in environments requiring corrosion resistance, high strength, and light weight. They are commonly found in chemical engineering, food and beverage industries, medical equipment, oil and gas pipelines, and building structures, and are frequently used in fluid transportation, gas transport, and structural support. The processing of thin-walled stainless steel pipes often utilizes metal cutting and welding equipment such as automatic and semi-automatic electric arc and plasma arc welding machines. Depending on the specific needs, pipes may require cutting. Due to their thin walls, these pipes are prone to deformation, thus requiring support during processing. Laser cutting is commonly used to reduce deformation during processing. However, existing laser cutting equipment has limited functionality, and pipes are easily deformed during production, leaving dents and defects on the circumference. Therefore, further processing is necessary, but existing equipment cannot meet these requirements. Based on this, this invention proposes a laser cutting processing device that can provide support during the processing of thin-walled stainless steel pipes.

[0028] Thin-walled stainless steel pipes are widely used in various industrial and commercial fields, especially in environments requiring corrosion resistance, high strength, and light weight. They are commonly found in chemical engineering, food and beverage industries, medical equipment, oil and gas pipelines, and building structures. The processing of thin-walled stainless steel pipes often utilizes metal cutting and welding equipment such as automatic and semi-automatic electric arc and plasma arc welding machines. Depending on the specific needs, pipes may require cutting, but due to their thin walls, they are prone to deformation. Therefore, support is generally required during processing. Laser cutting is commonly used to reduce deformation during processing. However, existing laser cutting equipment has limited functionality, and pipes are easily deformed during production, leaving dents and defects on the circumference. Therefore, further processing is necessary, but existing equipment cannot meet these requirements. Based on this, this invention proposes a laser cutting processing device that can provide support during the processing of thin-walled stainless steel pipes. It boasts rich functionality, can identify and repair defect locations, and can automatically transfer processing to ensure continuous operation.

[0029] The pipe is fitted onto the fixed positioning mechanism. The angle motor 14 works, which makes the positioning plate 16 rotate. The control motor 18 works, and the rotating ring 20 rotates. Under the action of the connecting rod 23, the radial seat 21 and the positioning rod 22 can move, thus completing the positioning and support of the inner side of the pipe to prevent deformation during processing. The cut-off part is supported and fixed by the moving positioning mechanism.

[0030] Specifically, before cutting, cleaning fluid can be transferred through the transfer box 7, and the spray nozzle 701 sprays the cleaning fluid onto the pipe. The cleaning position electric cylinder 9 controls the washing contact part 10 to contact its surface. By controlling the rotation of the pipe, the oxide layer, oil, dust and other impurities on the stainless steel surface are removed, ensuring that the stainless steel surface remains clean during the cutting process, thereby obtaining a flat and smooth cut surface.

[0031] Furthermore, the positioning mechanism moves so that its positioning rod 22 is located inside the pipe, and through the support, it drives the pipe to extend a preset distance. Then, the laser beam is controlled by the laser position electric cylinder 8 to perform cutting processing. During cutting, the pipe rotates continuously. After cutting, the cut part is located on the moving positioning mechanism. The position of the grinding motor 37 is controlled by the processing position electric cylinder 24. The grinding motor 37 is located between the pipe body and the cutting part. The grinding position electric cylinder 36 controls the grinding motor 37 to move between the two. The grinding motor 37 drives the grinding part to grind the end faces of both to remove burrs.

[0032] The cut-off workpiece portion is positioned on the moving positioning mechanism. The motor 3 operates, the lead screw 2 rotates, the pusher 4 moves, and the electric cylinder 5 controls the telescopic rod to push the cut-off workpiece portion to the transfer area, reserving space for the subsequent cut-off workpiece portion. Subsequently, through the above steps, the moving positioning mechanism repeatedly moves to the inside of the pipe, and the positioning rod 22 supports the pipe, allowing the pipe to extend a preset distance to continue the cutting process.

[0033] Furthermore, before cutting, the location of defects on the pipe can be detected. Specifically, the pipe is rotated, motor 325 operates, lead screw 326 rotates, slide 327 moves, and lead screw 40 controls telescopic contact rod 42 to contact the outer wall of the pipe. When there is a recessed area, telescopic contact rod 42 generates telescopic displacement, that is, the position sensor can output feedback telescopic signal to determine the location of defects on the pipe. Then, position motor 38 drives position disk 39 to flip, so that repair roller 2 41 faces the pipe. At the same time, on the inside of the pipe, motor 435 operates and lead screw 40 rotates, which can make slide 42 The position of the repair roller 34 is adjusted by sliding so that the positions of the repair roller 34 and the repair roller 41 correspond to each other. The repair cylinder 33 controls the repair roller 34 to contact the inner wall of the pipe. The repair roller 34 and the repair roller 41 simultaneously heat the defect. Then, the pipe is rotated to restore the dented area. Furthermore, when the detected defect position corresponds to the position of the positioning rod 22 and the inner and outer repair cannot be achieved, the pipe can be placed on the support part 29 for support. Then, the position of the positioning rod 22 is adjusted to avoid the defect position so as to facilitate the inner and outer repair operation.
