Description

Technical Field

[0001] The present application relates to the field of copper tube bending, and in particular to a device for bending and forming air-conditioning refrigeration copper tubes. Background Art

[0002] The copper tube in the air conditioner is the refrigerant tube of the air conditioner. Its main function is to store refrigerant and dissipate heat. The refrigerant tube of the air conditioner refers to the pipes that connect the heat exchanger, valves, compressors and other major refrigeration components in the air conditioning system through which the refrigerant flows. Most of the copper tubes in the air conditioner adopt a spiral structure. Due to the increase in the surface area of ​​the copper tube with a spiral structure, its thermal conductivity is 20 to 30 percent higher than that of a plain tube.

[0003] In the existing air-conditioning refrigeration copper tube bending and forming equipment, such as the Chinese patent with announcement number CN113458200A, an air-conditioning heat dissipation copper tube bending device is disclosed. Specifically, the copper tube is placed on the inner side of two clamping plates and the copper tube is contacted with the limit seat, and then the clamping plates are released, and spring two is reset. Spring two drives the clamping plates to contact the copper tube through elastic force, and fixes the copper tube inside the two clamping plates, so that the fixation of the copper tube is easier. After fixation, the servo motor is started, and the servo motor drives the bending rod to rotate through the turntable. The bending rod contacts the copper tube during the movement, and the bending rod continues to move after contacting the copper tube. The copper tube can be bent by the action force between the limit seat and the copper tube. When the bending rod contacts the stop rod, it cannot continue to move, thereby completing the fixed-angle bending of the copper tube.

[0004] The above-mentioned prior art can also realize the function of bending the copper tube, but on the first hand, when bending the copper tube in the above-mentioned prior art, the copper tube can only be bent at a certain angle, and the copper tube cannot be bent into a spiral structure, thereby reducing the thermal conductivity of the copper tube; on the second hand, when the copper tube is fully formed in the prior art, the formed copper tube is prone to rebound, and the formed copper tube is not easy to take out. Based on this, there is still room for improvement in the technology of the existing air-conditioning and refrigeration copper tube bending and forming equipment. Summary of the invention
