The lower area of ​​the filter screen 6 is a water storage chamber, and a stirring blade 8 is fixed outside the transmission shaft 9 located inside the multiple groups of heat sink fins 7. The cooling water is filtered through the filter screen 6 and falls into the water storage chamber. It is stirred by the stirring blades 8 and cooled by the heat sink fins 7. If the cooling effect is not good, the heat sink fins 7 can be replaced with semiconductor refrigeration plates.

[0045] Specifically, a water inlet pipe 13 and a water suction pipe are fixedly connected at the top of the cooling box 4. The other end of the water inlet pipe 13 passes through the sealing cover 1 and is connected to a plurality of nozzles 15 distributed in a circular manner at equal distances on the lower end surface of the sealing cover 1. The other end of the water suction pipe is connected to the water storage chamber. The water inlet pipe 13 and the water suction pipe are built-in with a one-way valve.

[0046] Specifically, a piston plate 19 is movably connected inside the cooling box 4 , and a spring 18 is fixed between the upper side of the piston plate 19 and the cooling box 4 .

[0047] Specifically, a slide groove 12 is opened inside the support frame 3, and a movable groove 23 is opened between the slide groove 12 and the cooling box 4. The bottom of the slide groove 12 and the bottom of the cooling box 4 are respectively rotatably connected with a guide wheel 22 and a guide wheel 1 20. A steel wire rope 21 is fixed to the bottom of the piston plate 19, and the other end of the steel wire rope 21 extends into the slide groove 12 through the guide wheel 1 20, the movable groove 23 and the guide wheel 2 22.

[0051] A processing method for producing pipe fittings, comprising the following steps:

[0052] S1. First, the user puts the workpiece to be processed into the carrier tube 10 through the feed port 11 on the carrier tube 10, and then closes the sealing plate at the feed port 11 to seal the feed port 11. When the device is not in use, the carrier tube 10 and the sealing cover 1 are located on the top of the support frame 3, above the cooling tube 2. Then the user controls the rotation of the motor 5 through the external controller, controls the internal threaded electromagnetic sleeve 24 to conduct electricity to generate magnetic force, and magnetically attracts the sealing cover 1 on the lower side. At this time, the motor 5 drives the transmission shaft 9 to rotate, and the transmission shaft 9 is threadedly connected with the internal threaded electromagnetic sleeve 24. Then the electromagnet 16 on the side of the sealing cover 1 conducts and runs and the electromagnetic slider 14 is magnetically fixed. Under the sliding action of the electromagnetic slider 14 and the slide groove 12, the rotation of the sealing cover 1 is limited, so that the sealing cover 1 is driven by the motor 5 to move down to the cooling tube 2 to start preparing for workpiece cooling.

[0053] S2. When the device is not in use, the bearing cylinder 10 and the sealing cover 1 are located at the top of the support frame 3, and the piston plate 19 in the cooling box 4 is located at the bottom of the cooling box 4 under the traction of the wire rope 21 and the electromagnetic slider 14. When the sealing cover 1 and the bearing cylinder 10 move downward, the wire rope 21 removes the traction force, and then the piston plate 19 squeezes the cooling water on the piston plate 19 under the upward pull of the spring 18. The cooling water is transported to the nozzle 15 distributed on the lower side of the sealing cover 1 through the water inlet pipe 13, and the nozzle 15 sprays and cools the pipe fittings to be processed on the lower side;

[0054] S3, when the sealing cover 1 is moved to the inside of the cooling cylinder 2, the internal thread electromagnetic sleeve 24 is powered off, and the motor 5 drives the transmission shaft 9 to continue to rotate, and the transmission shaft 9 drives the cleaning brush 17 to roll and clean the workpiece in the bearing cylinder 10. During this process, the nozzle 15 continues to spray cooling water to cooperate with the cleaning brush 17 to scrape and clean the workpiece to remove surface dirt and iron filings;

[0055] S4, after the cleaning is completed, the internal thread electromagnetic sleeve 24 continues to conduct electricity, and the electromagnet 16 is powered off at this time, so that it is fixed by magnetic attraction with the electromagnetic slider 14, and then the motor 5 continues to rotate, and the transmission shaft 9 cooperates with the internal thread electromagnetic sleeve 24 to drive the sealing cover 1 and the bearing tube 10 to rotate synchronously, so that the motor 5 drives the sealing cover 1 to rotate, drives the bearing tube 10 to rotate, and centrifugal dehydration is performed on the workpiece in the bearing tube 10, and then the electromagnet 16 conducts electricity, the motor 5 reverses, cooperates with the internal thread electromagnetic sleeve 24, and the sealing cover 1 and the bearing tube 10 move up and reset, and the user removes the internal workpiece;

[0056] The cooling water is filtered through the filter 6 and falls into the water storage chamber, where it is stirred by the stirring blades 8 and cooled by the heat sink fins 7. If the cooling effect is not good, the heat sink fins 7 can be replaced with semiconductor refrigeration sheets.

[0057] Subsequent users can also set the water suction pipe inlet pipe 13 at the bottom of the piston plate 19, eliminate the structures such as the wire rope 21 and the movable groove 23, and realize the up and down displacement of the piston plate 19 through the magnetic slider to cooperate with the sealing cover 1 to realize the suction supply of the water source.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
