Among them, the aluminum tube in the water tank condenser of new energy vehicles is usually used for heat transfer, and transfers the heat absorbed in the coolant to the surrounding cooling medium to achieve heat dissipation. When the condenser aluminum tube is connected to other components, in order to improve the tightness of the connection between the components, the aluminum tube usually needs to be expanded.

[0031] S6. When the forging head group reaches the end of the aluminum tube, the light sensor at the support tube transmits data to the data acquisition and processing center, so that the oil supply valve opens, and the lubricating oil enters the support tube from the control arm, and then sprays out from the nozzle in a mist-like ring shape; so that the inner wall of the aluminum tube processing end is covered with lubricating oil, so as to prevent the pressure head from entering the aluminum tube during forging, causing cracks in the aluminum tube;

[0032] S7. After the forging is completed, the loading module withdraws the processed aluminum tube and moves to the loading area for taking.
