[0034] In an alternative embodiment of the present invention, as Figure 10 shown, the punching die includes: a punching plate I 23, a punching plate II 24, a punching plate III 25, a short slide rail 26, a hydraulic cylinder II 27, a hydraulic cylinder III 28, and a hydraulic cylinder IV 29; both ends of the punching plate I 23, the punching plate II 24, and the punching plate III 25 are slidably installed on the short slide rail 26, the short slide rail 26 is fixedly installed on the upper surface of the workbench 1, the cylindrical punching head on the punching plate II 24 passes through the round hole on the punching plate I 23, and the cylindrical punching head on the punching plate III 25 passes through the round holes on the punching plate II 24 and the punching plate I 23, and the cylinder bodies of the hydraulic cylinder II 27, the hydraulic cylinder III 28, and the hydraulic cylinder IV 29 are installed at different positions on the right-angle bracket at the upper edge of the workbench 1, the piston rod of the hydraulic cylinder II 27 is fixedly connected to the punching plate I 23, the piston rod of the hydraulic cylinder III 28 is fixedly connected to the punching plate II 24, and the piston rod of the hydraulic cylinder IV 29 is fixedly connected to the punching plate III 25.

[0036] In an alternative embodiment of the present invention, as Figure 8 、 Figure 9 shown, there are two limit baffles 16. When one rises to the workbench 1, the other must be under the workbench 1.

[0037] Working principle: For the processing of the manifold, it is necessary to stamp flat grooves and round holes on the round tube to facilitate the assembly of the subsequent condenser. When this invention is in use, first place the round tube on the feeding groove 30, and the upper end of the round tube contacts the slider II 13. When the upper end of the round tube contacts the slider II 13, the stepping motor II 14 starts immediately. The rotation of this motor drives the screw rod II 12 to rotate, thereby causing the slider II 13 to slide smoothly inward along the established track. During this process, the friction force generated by the contact between the rubber at the lower end of the slider II 13 and the upper edge of the round tube serves as the driving force to lead the round tube to slide inward synchronously until the round tube accurately sleeves on the inner lining tube 2 until the round tube catches the elastic piece 9 on the inner lining tube 2. Subsequently, the stepping motor III 22 starts, driving the worm 21 to rotate. The worm 21 drives the worm wheel 20 to rotate. 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 and the other to descend. The rising limit baffle 16 blocks the round tube. Subsequently, the hydraulic cylinder I 8 drives the notch extruder 7 to squeeze inward, thereby stamping a flat groove on the round tube;

[0038] After the flat groove is stamped, the limit baffle 16 on this side resets and descends under drive. Subsequently, the stepping motor I 6 starts, driving the screw rod I 4 to rotate, thereby driving the slider I 3 to slide, and thus driving the inner lining tube 2 to slide to the other end on the workbench 1 and stopping when it is concentric with the discharging groove 31. Subsequently, the limit baffle 16 at the stopping position rises under the drive of the lever 18 to limit the round tube again. Subsequently, according to actual needs, start one of the hydraulic cylinder II 27, the hydraulic cylinder III 28 or the hydraulic cylinder IV 29, thereby driving one of the punching plates I 23, the punching plate II 24 or the punching plate III 25 to squeeze towards the round tube to punch a round hole in the round tube. After punching, the slider II 13 slides towards the discharging groove 31 under drive, thereby driving the processed manifold to the discharging groove 31.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
