During the sliding process of the frame 2, the liquid supply part is started to supply liquid to the nozzle 201, and the nozzle 201 can be in advance. Spraying lubricating oil on the copper tube can, on the one hand, reduce the friction and heat generated during the shrinking process, prevent wear and damage to the surface of the copper tube and the shrinking mold, and improve the service life and processing quality. On the other hand, it can avoid the safety hazards and low efficiency caused by manual application, and improve the use effect. A fixed seat 5 is rotatably arranged on the processing table 1, and a motor for driving the fixed seat 5 to rotate is fixedly arranged on the processing table 1. The motor is preferably a servo motor. When in use, when the other end of the copper tube needs to be shrunken, the fixed seat 5 can be rotated 180 degrees by starting the motor.

Among them, a lower clamping plate 504 for clamping the copper tube is fixedly arranged on the fixed seat 5, and an upper clamping plate 505 corresponding to the lower clamping plate 504 is lifted and lowered on the fixed seat 5.

After the processing is completed, the frame 2 returns under the elastic force of the spring. At this time, the connecting rod 203 can pull the piston block 204 to slide in the piston chamber 4, and the liquid in the oil storage tank 107 can be drawn into the piston chamber 4 through the liquid inlet pipe 401, thereby improving the use effect.

When in use, by threading the push rod 301 on the L plate 3, the distance between the pad and the L plate 3 can be adjusted accordingly according to the length of the processing mold, that is, the process of the pad abutting against the frame 2 must precede the contact between the processing mold and the copper tube, so that the nozzle 201 can spray the lubricating oil on the copper tube in advance, and the interval between the two will not be too long, so as to prevent the lubricating oil from completely slipping off the copper tube.
