Description

Technical Field

[0001] The utility model relates to the field of pipe arc punching machines, in particular to an automatic feeding chain of the pipe arc punching machines. Background Art

[0002] Pipes are used to transport liquids, gases or solids. They are usually made of metal, plastic, fiberglass and other materials. They are widely used in piping systems in construction, industry, agriculture and other fields. Pipe arc punching machine is a machine used to process metal pipes. It is usually used for stamping and bending on pipes. It can make holes, protrusions or depressions on pipes, and can also bend pipes into required angles or shapes. These machines are widely used in the metal processing industry to manufacture various types of pipes and metal components. The automatic feeding chain of pipe arc punching machine is a chain conveyor for automatic feeding. This chain conveyor is usually used in conjunction with pipe punching and arc welding equipment to realize automatic feeding of pipes for the next step of punching or arc welding. The automatic feeding chain can improve production efficiency, reduce labor costs, and ensure high-precision positioning throughout the entire processing process.

[0003] After searching the existing Chinese patent: Publication No., CN219313713U, an automatic feeding structure for a ring chain forming machine, relates to the technical field of ring chain forming machines, comprises a ring conveyor chain and a motor arranged on one side of the outer wall of the ring conveyor chain, and a feeding assembly is arranged at the other end of the ring conveyor chain, which solves the problem that the manual feeding action requires the operator to repeatedly bend and stand up, resulting in a high labor intensity for the operator. The operator can place the material on the upper end of the placement table, and drive the long block to push the material on the upper end of the placement table to the upper end of the U-shaped block by starting the third electric telescopic column. The first electric telescopic column at the lower end of the U-shaped block will drive the U-shaped block and the material on the upper end to rise, and push the material to the same height as the ring conveyor chain, and then push the material to the upper end of the ring conveyor chain by pushing the push block, without the need for manual bending back and forth to feed the material, thereby reducing the labor intensity of the workers.

[0004] The above patent realizes pushing materials to the upper end of the ring-shaped conveyor chain belt by pushing the push block, without the need for manual bending back and forth to load materials, thereby reducing the labor intensity of workers. The height of the ring-shaped conveyor chain belt in the above patent is fixed and cannot be adjusted according to actual conditions. When conveying pipes, debris falling from the pipes will adhere to the surface of the conveyor chain belt. Larger debris may generate resistance on the conveyor chain belt, causing the chain belt to get stuck or block the conveyor system. The debris may cause the chain belt to run unsmoothly on the roller or transmission system, thereby reducing the efficiency of the conveyor system and increasing the need for maintenance and cleaning. The accumulated debris may cause wear or scratches on the surface of the conveyor chain belt, thereby reducing its service life. The above patent cannot assist the staff in cleaning the conveyor chain belt.

[0005] Therefore, it is necessary to invent an automatic feeding chain for a pipe arc punching machine to solve the above problems. Utility Model Content
