Description

Technical Field

[0001] The utility model relates to the technical field of copper tube bending, in particular to an anti-flattening bending machine for copper tubes. Background Art

[0002] During the installation of air conditioners, copper pipes often play a very important role. Due to their good thermal conductivity, copper is used as the liquid pipe for heat exchange in air conditioners, making them widely used in the installation process. Due to the different installation positions of air conditioner condensers, it is sometimes necessary to bend the copper pipes at a certain angle using a copper pipe bending machine.

[0003] Existing copper tube bending machines typically include a fixed assembly that radially limits the copper tube and a rotating assembly that bends the copper tube. When bending the copper tube, the rotating assembly clamps the portion of the tube to be bent, while the fixed assembly limits the remaining portion. However, existing fixed and rotating assemblies typically use fixed blocks with fixed-size grooves and fixed-shaped clamps, which cannot adapt to bending copper tubes of different diameters. The copper tube is unstable during bending, and when the rotating assembly drives the copper tube to bend, the copper tube does not bend according to the original trajectory, resulting in the copper tube being easily flattened during bending. Utility Model Content

[0004] Based on the technical problems existing in the above-mentioned prior art, the utility model provides an anti-flattening bending machine for copper tubes, which can adapt to the bending of copper tubes of different diameters, thereby reducing the situation where the copper tubes are flattened during bending due to incompatibility with diameter changes.
