Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a long U-tube bending machine for radiator copper tubes. Background Art

[0002] Radiator is an important and basic component in the hot water heating system. It transfers heat from the heat source to the surrounding environment through conduction, convection and radiation. In the production and processing of radiators, in order to ensure the heat dissipation efficiency and reduce the space occupied by the radiator, some copper tubes are usually bent into U-shaped tubes to extend the time required for liquid to pass through the copper tubes. When bending the copper tubes, using a tube bending machine to assist the staff in bending can greatly improve production efficiency. A tube bending machine refers to a machine used for bending tubes. It is widely used in the laying and repair of pipelines in power construction, road and railway construction, bridges, ships, etc.

[0003] The existing pipe bending machine can only bend one group of copper pipes when in use, has low working efficiency and is inconvenient to use.

[0004] The existing patent (publication number: CN220277970U) discloses a long U-tube bender for radiator copper tubes. The bender solves the problem that the bender needs to apply pressure to the outside of the cylindrical tube to bend it by setting a bender main body and a positioning airbag. In order to avoid deformation of the tube during the bending process due to fewer stress points, the sizes of the bender wheel and the pressure wheel of the bender are usually set according to the size of the required tube. However, when it is necessary to bend tubes of various sizes, it is necessary to purchase a variety of different types of bender machines, which greatly increases the production cost. When bending the copper tube, the copper tube is sleeved on the outside of the positioning airbag, and the positioning airbag is inflated by an air pump to expand and squeeze the inner wall of the copper tube, and the inner wall of the copper tube is elastically supported, so that the copper tube will not be accidentally deformed due to the small stress surface when it is bent by the bender main body. Then, the bender main body can be suitable for bending copper tubes of various sizes, thereby improving the versatility of the bender.

[0005] However, the above technical solution still has certain defects. When the pipe bending machine is used, it is first necessary to use a copper tube in conjunction with an air bag to fix the copper tube, and then insert the copper tube between the bending groove and the limit block to limit the copper tube, so as to cooperate with the limit block to drive the copper tube to be bent. However, the pipe bending machine can only bend one copper tube at a time when in use, and cannot process multiple groups of copper tubes at the same time. The operation is relatively cumbersome, which increases the workload of the staff and is inconvenient to use. Therefore, a long U-tube bending machine for radiator copper tubes is proposed.
