Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, in particular to a straightening device for copper tube coiling. Background Art

[0002] Copper tubes, also known as red copper tubes, are seamless tubes formed by pressing and drawing. During the production process of copper tubes, since copper tubes are relatively easy to bend, some copper tubes that are squeezed and deformed need to be straightened during the processing.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN218963684U discloses a copper tube straightening device, including a mounting seat, a mounting frame fixedly provided on the top of the mounting seat, a conveying mechanism installed on the inner side of the mounting frame, a second motor fixedly provided on the top of the mounting seat, a second gear fixedly provided on the output end of the second motor, a mounting plate fixedly provided on the inner side of the mounting frame, the outer wall of the mounting plate is rotatably connected with a rotating sleeve, the rotating sleeve is driven to rotate by the second motor, and the mounting sleeve is driven to rotate by the rotating sleeve, and one end of the copper tube is passed through the mounting sleeve and the mounting plate, and inserted between the first pressure roller and the second pressure roller. When the mounting sleeve rotates, it can drive multiple cleaning brushes inside it to rotate, and the outer wall of the copper tube is cleaned by the cleaning brush, so that the cleaned copper chips are discharged through the chip discharge hole on the mounting sleeve, thereby avoiding the pressure roller from squeezing the copper chips in the subsequent copper tube straightening process, so that the copper chips cause scratches on the surface of the copper tube, affecting the aesthetics of the copper tube surface.

[0005] However, the above patent still has problems that need to be improved during actual use. The most obvious one is that the pressure roller will cause wear after repeated use, and untimely replacement will affect the straightening effect and efficiency, and the cleaning brush is difficult to use with copper tubes of different specifications.

[0006] Therefore, we proposed a copper tube coil straightening device to solve the above-mentioned drawbacks. Utility Model Content
