After the positioning is completed, the clamp is started to clamp the heat exchange tube body to ensure that the workpiece will not be displaced or shaken during the working process, affecting the dimensional accuracy of the product. Then the tube cutting operation is completed by the tube cutting machine, and compressed air is connected through the compressed air connection port to blow away the debris and emulsion generated by the cutting from the inside of the tube body. After the tube cutting work is completed, the motor of the screw linear drive mechanism of the first pushing device is started again to retract the tank body, and the lifting plate of the first pushing device lifts the next tube body to be processed while transferring this cut tube body to the area of ​​the oblique feeding rod of the next workstation.
