[0002] Heat exchange tubes are one of the components of a heat exchanger, placed within the cylinder and used to exchange heat between two media. They possess high thermal conductivity and excellent isothermal properties. They are known as heat transfer superconductors, capable of rapidly transferring heat energy from one point to another with virtually no heat loss. Their thermal conductivity is thousands of times greater than that of copper. However, during the production process, heat exchange tubes can deform due to bumps and collisions, requiring a heat exchange tube nozzle straightening device to correct these deformations.

[0003] For example, Chinese patent application number CN202220660539.X discloses a nozzle shaping device for processing heat exchange tubes, comprising support legs, the upper portion of which is fixedly connected to a workbench, a mounting block provided in the middle portion above the workbench, three clamping blocks arranged in a matrix in the middle portion of the upper end of the mounting block, the mounting block provided with a cavity on the outer side of the clamping block, the cavity provided with a push plate matching the clamping block, a push rod provided on the side of the push plate close to the clamping block, the push rod passing through the mounting block on the side away from the push plate and fixedly connected to the clamping block, and a support plate provided on the upper end of the support legs.
