The discharge piece 200 is used to arrange a plurality of pipe fittings. The pushing mechanism 300 is fixedly installed at one end of the base 100. The pushing mechanism 300 is used to push the net into the pipe fitting. The pushing mechanism 300 is used to push the pipe fitting forward in the discharge piece 200. The clamping mechanism 400 The mechanism 400 is located at the other end of the base 100, the clamping mechanism 400 is used to clamp and fix the pipe fitting, the front shrinking mechanism 500 is located on one side of the clamping mechanism 400, the front shrinking mechanism 500 is used to shrink one end of the pipe fitting, the rear shrinking mechanism 600 is located on the other side of the clamping mechanism 400, the rear shrinking mechanism 600 is used to shrink the other end of the pipe fitting, the number of double-headed hydraulic rods 700 is two, the double-headed hydraulic rods 700 are fixedly installed between the front shrinking mechanism 500 and the rear shrinking mechanism 600, and the double-headed hydraulic rod 700 is used to drive the front shrinking mechanism 500 and the rear shrinking mechanism 600 to extrude the pipe fitting.

[0020] Embodiment 1

[0021] like Figures 1 to 4 As shown, in the present embodiment, the pushing mechanism 300 includes an electric push rod 320, which is fixedly mounted at one end of the base 100, and the output end of the electric push rod 320 is fixedly connected to a joint seat 330, and one side of the joint seat 330 is fixedly connected to a pushing rod 310, and one end of the pushing rod 310 is slidably plugged into the discharge piece 200, and one end of the pushing rod 310 is fixedly connected to an insertion head 312, and the insertion head 312 is used to push the leaking net into the pipe fitting, and one end of the pushing rod 310 is used to push the pipe fitting forward in the discharge piece 200, and the top ends of the outer walls of the pushing rod 310 and the insertion head 312 are both provided with a recessed portion 311.

[0022] In a specific implementation, the push rod 310 is driven by the electric push rod 320 to insert into the discharge piece 200. When the push rod 310 moves forward, the insertion head 312 presses the leakage net, and the push rod 310 continues to move forward. At this time, the clamping mechanism 400 is in a clamping state for the front end pipe fitting, and the advancing insertion head 312 presses the leakage net into the rear end pipe fitting. Then, the advancement of the push rod 310 drives the clamping mechanism 400 to release the clamping of the front end pipe fitting, and the continued advancement of the push rod 310 pushes the multi-tube pipe fitting to move forward. The pipe fitting moves forward one position, and then the electric push rod 320 drives the pushing rod 310 to retreat. Through the setting of the lower recess 311, the lowest pipe fitting in the pipe hopper 210 falls into the lower recess 311, thereby clamping the original pipe fitting at the rear end, thereby preventing the pushing rod 310 from driving the pipe fitting back when retreating. After the pushing rod 310 is reset, the new pipe fitting and the leaking net fall into the discharging piece 200, so as to press the leaking net into the pipe fitting, and continuously supply the pipe fitting into the clamping mechanism 400.

[0023] like Figures 3 to 7As shown, in this embodiment, the clamping mechanism 400 includes a fixed disk 430 and a sleeve 410, one end of the sleeve 410 is fixedly connected to the inner wall of the fixed disk 430, a plurality of plug rods 431 are equidistantly fixedly connected to one side wall of the fixed disk 430, a movable disk 440 is arranged on one side of the fixed disk 430, the plug rod 431 is slidably plugged with the movable disk 440, the inner wall of the sleeve 410 is slidably connected with three annular equidistantly arranged pressure members 420, the outer side wall of the pressure member 420 is provided with an extrusion module 450, the extrusion module 450 is located between the fixed disk 430 and the movable disk 440, the output end of the electric push rod 320 is transmission-connected with the movable disk 440, the extrusion module 450 includes a slide groove member 452 and two connecting rods 451, the slide groove member 452 is connected to the clamping mechanism 400 One side wall is fixedly connected, a slide seat 453 is rotatably connected between one ends of the two connecting rods 451, the slide seat 453 is slidably connected to the slide groove member 452, the other end of one connecting rod 451 is rotatably connected to one side wall of the fixed disk 430, the other end of the other connecting rod 451 is rotatably connected to the pressure member 420, a plurality of brackets 441 are equidistantly fixedly connected to the outer side wall of the movable disk 440, a pushing rack 470 is fixedly connected between the plurality of brackets 441, a gear rod 340 is fixedly connected to the bottom end of the electric push rod 320, a transmission gear 350 is arranged between the gear rod 340 and the pushing rack 470, the transmission gear 350 is rotatably connected to the base 100, an eccentric wheel 360 is fixedly connected to the top end of the transmission gear 350, an extrusion spring 460 is fixedly connected to one side wall of the bracket 441, and the extrusion spring 460 is fixedly connected to the front shrinking mechanism 500.

[0024] When the push rod 310 is implemented, it drives the gear rod 340 to move forward. When the push rod 310 presses the leakage net into the pipe fitting, the forward gear rod 340 meshes with the transmission gear 350, thereby driving the eccentric wheel 360 to rotate. The eccentric wheel 360 rotates to squeeze the push rack 470, so that the movable plate 1 440 overcomes the elastic force of the squeezing spring 460 and moves forward. The movable plate 1 440 pulls the slide seat 453 through the slide groove part 452, so that the multiple pressure parts 420 deviate from each other, thereby making the multiple pressure parts 420 release the clamping of the pipe fitting, making it convenient for the push rod 310 to drive the subsequent pipe fittings to move forward. When the push rod 310 is withdrawn, the movable plate 1 440 moves backward under the pressure of the squeezing spring 460, so that the multiple pressure parts 420 clamp and fix the pipe fitting, and then the front shrinking mechanism 500 and the rear shrinking mechanism 600 shrink the pipe fitting. The present invention also provides a processing technology for refrigerator refrigeration pipe fittings, which specifically includes the following steps: Step 1: copper tube cutting, cutting the material tube into copper tube fittings of predetermined length; Step 2: Ultrasonic cleaning of pipe fittings; Step 3: After the filter screen is pressed into the pipe through the refrigeration pipe processing device, the two ends of the pipe are reduced in diameter; Step 4: Put caps on both ends of the pipe fittings after the diameter reduction process, and then package the pipe fittings for storage.
