Specifically, the pipe strip 2 on the unpowered support 1 is guided by the feeding guide wheel set 333 into the roller straightening device 332 for straightening, and then clamped and pulled by the pipe body conveying cylinder 335, so that the straightened pipe body passes through the pipe body positioning and clamping cylinder 336 and enters the pipe body cutting box 337, and extends into the first pipe body pneumatic clamping seat 338 for clamping and fixing. In this process, the first pipe body pneumatic clamping seat 338 is adjusted by the cylinder built in the pipe body straightening base 331, and its length is fixed through the cooperation of the guide rails and sliders on the pipe body straightening base 331. When the pipe body cutting box 337 is working, the pulling electric screw rod 334 stops driving the pipe body conveying cylinder 335, while the pipe body positioning and clamping cylinder 336 and the first pipe body pneumatic clamping seat 338 clamp the pipe body at the same time.

[0038] The rear tube end shrinking assembly 35 includes a rear tube end shrinking base 351 fixedly mounted on the workbench 31 by bolts and having a guide rail installed on the top, a punching displacement plate 352 movably assembled with the guide rail on the rear tube end shrinking base 351 through a slider, a pipe pushing column 353 fixedly mounted on the punching displacement plate 352 by a fixing block, a shrinking punching cylinder 354 fixedly mounted on the rear tube end shrinking base 351 and having its output end connected to the punching displacement plate 352, a shrinking punching die 355 fixedly mounted on the punching displacement plate 352 and located on one side of the pipe pushing column 353, and a second pipe body pneumatic clamping seat located in front of the pipe pushing column 353 and the shrinking punching die 356 and fixedly mounted on the workbench 31 by bolts. 356. Specifically, when the rear tube end shrinking component 35 is working, the second tube body pneumatic clamping seat 356 is first opened, and then the Y-axis tube moving mechanism 322 clamps the copper tube that has passed the front tube end expanding component 34 for front end punching and expanding processing to the front end of the second tube body pneumatic clamping seat 356. At this time, the shrinking and punching cylinder 354 drives the punching displacement plate 352 to move forward, and the copper tube clamped by the Y-axis tube moving mechanism 322 is pushed into the second tube body pneumatic clamping seat 356 through the pushing column 353 and then reset, so as to facilitate the clamping of the second tube body pneumatic clamping seat 356. Then the shrinking and punching cylinder 354 drives the punching displacement plate 352 to move forward again, so that the shrinking and punching die 355 is inserted into the copper tube for punching processing, so that the copper tube completes the shrinking process.

[0039] The pipe bending assembly 36 includes a pipe bending base 361 fixed to the side of the core pulling assembly 37 and fixed to the side of the workbench 31 at the lower end, a copper pipe feeding robot 362 mounted on the side of the pipe bending base 361, which transfers the copper pipe pressing block 363 above the pipe bending base 361, a tensioning cylinder 364 mounted below the pipe bending base 361 for controlling the movement of the copper pipe pressing block 363, a push block 365 mounted side by side on one side of the copper pipe pressing block 363 and driven by the built-in cylinder of the pipe bending base 361, and a fixedly mounted below the pipe bending base 361 and having its output end extending through the pipe bending base 361. The angle adjustment motor 366 is provided, and a sleeve seat 367 is mounted on the output end of the angle adjustment motor 366. A bending die 368 is fixedly mounted above the sleeve seat 367 and cooperates with the copper tube pressing block 363. Specifically, the tension cylinder 364 drives the copper tube pressing block 363 to cooperate with the bending die 368 to fix the copper tube. Then the cylinder built into the tube bending base 361 drives the push block 365 to push the copper tube to bend. After the bending is completed, the angle adjustment motor 366 drives the sleeve seat 367 to rotate, driving the bent copper tube to rotate, so that the tube mouth at the bent end faces the core pulling assembly 37 again.

[0040] The copper pipe loading manipulator 362 includes a hinged seat 3621 fixedly installed on the elbow base 361, a loading cylinder 3622 fixedly installed on the hinged seat 3621, a loading arm 3623 hingedly assembled on the elbow base 361 and having its lower end hingedly installed on the output end of the loading cylinder 3622, a pick-up telescopic cylinder 3624 fixedly installed on the loading arm 3623 by bolts, and a pipe-passing column 3625 assembled on the output end of the pick-up telescopic cylinder 3624. Specifically, through the telescopic movement of the loading cylinder 3622, the driving loading arm 3623 can be driven between the rear pipe end necking component 35 and the elbow component 36. After the Y-axis pipe transfer mechanism 322 takes out the copper pipe that has completed the rear end necking process from the rear pipe end necking component 35 and moves it between the rear pipe end necking component 35 and the elbow component 36, the pick-up telescopic cylinder 3624 can drive the pipe-passing column 3625 to penetrate into the copper pipe, take out the copper pipe from the Y-axis pipe transfer mechanism 322, and transfer it to the copper pipe pressing block 363, so that the copper pipe is fixed under the cooperation of the copper pipe pressing block 363 and the bending die 368, and finally the bending process is carried out.

Specifically, the metal core bar 373 is aligned with the copper pipe fixed under the cooperation of the copper pipe pressing block 363 and the bending die 368, and the core-pulling moving table 372 is driven to move forward by the driving lead screw, so that the metal core bar 373 is inserted into the bent end of the copper pipe. When the push block 365 driven by the cylinder built in the elbow base 361 pushes the copper pipe to be bent, the metal core bar 373 follows the bending due to its sufficient length and its own elasticity. By the metal core bar 373, the situation of deformation and collapse of the copper pipe during the bending process can be avoided, providing a quality guarantee for the subsequent copper pipe sleeving process. After the bending is completed, the angle adjustment motor 366 drives the sleeve seat 367 to rotate, driving the bent copper pipe to rotate, so that the pipe orifice at the bent end faces the core-pulling component 37 again. At this time, the metal core bar 373 is restored to a straight state due to elasticity, and then the core-pulling moving table 372 can be driven to move backward by the driving lead screw, so that the metal core bar 373 is withdrawn from the bent end of the copper pipe.

Specifically, after the copper pipe rotary clamp 384 clamps the elbow copper pipe conveyed by the X-axis pipe transfer mechanism 323, it rotates through the rotary motor 3836 to make the collar end of the clamped elbow copper pipe face down, and then moves downward under the contraction of the lifting adjustment cylinder group 3835, so that the elbow copper pipe cooperates with the collar frame 385 to complete the collar fitting;

[0044] The collar frame 385 includes a column 3851 fixedly installed with the collar frame 381, a collar support plate 3852 fixedly installed at the upper end of the column 3851, a collar die base 3853 fixedly installed on the collar support plate 3852 and in butt - connection and communication with the welding ring feeding vibrating disk 382, a top - material cylinder 3854 fixedly installed below the collar support plate 3852 and with its output end penetrating into the inner hole of the collar die base 3853, and a laser sensor 3855 assembled on one side above the collar support plate 3852 through a bracket for detecting the collar in the collar die base 3853.
