[0037] Working principle: The processing of the collecting pipe requires punching flat grooves and round holes on the round tube to facilitate the assembly of the condenser later. When the present invention is used, the round tube is first placed on the feed trough 30, and the upper end of the round tube contacts the slider Ⅱ13. When the upper end of the round tube contacts the slider Ⅱ13, the stepper motor Ⅱ14 is immediately started. The operation of the motor drives the screw rod Ⅱ12 to rotate, thereby causing the slider Ⅱ13 to slide smoothly inward along the predetermined track. In this process, the rubber at the lower end of the slider Ⅱ13 and the upper edge of the round tube generate friction through contact. The driving force leads the round tube to slide inward synchronously until the round tube is accurately sleeved on the inner liner tube 2, until the round tube clamps the spring piece 9 on the inner liner tube 2, and then the stepper motor III 22 is started to drive the worm 21 to rotate, the worm 21 drives the worm wheel 20 to rotate, and the worm wheel 20 drives the lever 18 to rotate through the transmission shaft 19, thereby driving one of the two limit baffles 16 to rise upward and the other to fall, and the raised limit baffle 16 blocks the round tube, and then the hydraulic cylinder I 8 drives the notch extruder 7 to squeeze inward, thereby punching a flat groove on the round tube;

[0038] After the flat groove is punched, the limit baffle 16 on this side is driven to reset and lower, and then the stepper motor Ⅰ6 is started, driving the screw rod Ⅰ4 to rotate, thereby driving the slider Ⅰ3 to slide, thereby driving the inner lining tube 2 to slide to the other end of the workbench 1, and slides to stop concentric with the discharge trough 31, and then the limit baffle 16 on the stop position side is raised by the drive of the lever 18, and the round tube is limited again, and then according to actual needs, one of the hydraulic cylinders Ⅱ27, Ⅲ28 or Ⅳ29 is started, thereby driving one of the punching plates Ⅰ23, Ⅱ24 or Ⅲ25 to squeeze the round tube, and punch out a round hole in the round tube. After the punching is completed, the slider Ⅱ13 is driven to slide toward the discharge trough 31, thereby driving the processed collecting pipe to the discharge trough 31.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
