Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning fittings processing, in particular to a plane bending device for air-conditioning pipes. Background Art

[0002] Copper tubes are used in air-conditioning pipe assemblies due to their good thermal conductivity and ductility. Since there are a large number of copper tubes on air-conditioning pipe assemblies and the wiring is complicated, the copper tubes need to be pre-bent. At present, most of the shaping of air-conditioning pipes on the market is done manually, which has low work efficiency and poor control of manual operation precision. In addition, some of them are adjusted and bent by shaping equipment, but when bending the air-conditioning pipes, only air-conditioning pipes of the same specification and length can be processed, and the scope of application is narrow. Therefore, an air-conditioning pipe plane bending equipment is proposed to solve the above problems. Utility Model Content
