A guide groove 10 is opened at the edge of the turntable 8. The guide groove 10 is inclined, and the guide groove 10 and the connecting column 11 are slidably connected.

[0032] Furthermore, the power structure includes a motor 14, which is fixedly mounted above the processing platform 1. A gear 13 is fixedly sleeved on the outside of the output end of the motor 14, and teeth 12 are fixedly mounted on the outer surface of the turntable 8. The teeth 12 are meshed with the gear 13.

[0033] Specifically, the positioning mechanism includes a rod 18, which is fixedly installed on the side of the mold core 17 close to the supporting plate 2, a limiting member 19 is fixedly installed on the side of the rod 18 away from the mold core 17, a positioning member 20 is fixedly installed on the side of the limiting member 19 away from the rod 18, and a correction device is arranged between the limiting member 19 and the turntable 8.

[0034] Furthermore, the correction device includes two groups of push blocks 21, which are respectively located above and below the limiter 19. The push blocks 21 are connected to the mold shell 15 through an elastic structure, and the push blocks 21 are connected to the turntable 8 through a lifting assembly.

[0035] Furthermore, the elastic structure includes a movable groove 22, which is opened on the outside of the mold shell 15. A slide plate 23 is slidably inserted inside the movable groove 22. The slide plate 23 is connected to the push block 21 through a supporting structure. A spring No. 1 movably inserted inside the movable groove 22, and the spring No. 1 24 and the slide plate 23 are fixedly connected.

[0036] Specifically, the support structure includes a fixing frame 25, which is fixedly installed above the slide plate 23, and a column 26 is fixedly inserted inside the fixing frame 25.

[0038] Working principle: Under the action of the processing platform 1, the copper tube passes through the two groups of positioning plates 3 and falls onto the top of the supporting plate 2, and the motor 14 is connected to the external power supply. The motor 14 drives the gear 13 to rotate. Since the gear 13 and the teeth 12 are meshed, the gear 13 can drive the turntable 8 to rotate through the teeth 12. The turntable 8 is connected to the fixed plate 4 through the rotating seat 9. When the turntable 8 rotates, it can drive the connecting column 11 to move through the guide groove 10. The connecting column 11 drives the slider 7 to move inside the slide groove 6, and the slider 7 drives the support frame 5 to move synchronously. At this time, the supporting plate 2 and the two groups of positioning plates 3 can move synchronously, and the supporting plate 2 and the two groups of positioning plates 3 are close to or away from each other.

[0039] When the supporting plate 2 and the two sets of positioning plates 3 are close to each other, copper tubes of different sizes can be positioned so that the center of the copper tube and the center of the mold shell 15 are on the same horizontal line, so that when copper tubes of different sizes are processed, the copper tubes can be quickly positioned, which is beneficial to improving processing efficiency.

[0040] At the same time, when the turntable 8 rotates, it can drive the adjusting block 30 to move synchronously. The end of the adjusting block 30 close to the cross plate 28 is inclined. When the adjusting block 30 contacts the cross plate 28, it can push the cross plate 28 to move toward the inside of the slide plate 23. At this time, the cross plate 28 drives the push plate 29 to rotate, and the push plate 29 can push the push block 21 to move upward inside the fixed frame 25. At this time, under the action of the column 26, the second spring 27 is deformed by force, and the two groups of push blocks 21 are in contact with the limit member 19, so that the center of the limit member 19 and the center of the copper tube can be on the same horizontal plane. Under the action of the rod 18, the limit member 19 can drive the mold core 17 to move synchronously inside the cavity 16, so that the mold core 17 will not contact the inner wall of the mold shell 15 under the action of gravity, so that when the copper tube is processed, the force on the light tube is more uniform, and the thickness of the copper tube after processing is more uniform.

[0041] A pushing mechanism is arranged above the processing platform 1. The pushing mechanism is located on the side of the supporting plate 2 away from the mold shell 15. The pushing mechanism pushes the copper tube toward the mold shell 15. The copper tube contacts the positioning member 20 and is sleeved on the outside of the positioning member 20. The copper tube continues to move. The copper tube contacts the pushing block 21 and drives the pushing block 21 to move. The pushing block 21 drives the slide plate 23 to move inside the movable groove 22. At this time, the No. 1 spring 24 is deformed by force. It should be noted that the elastic coefficient of the No. 1 spring 24 is greater than that of the No. 2 spring 24. 7, when the push block 21 moves, the cross plate 28 is separated from the adjusting block 30, and under the elastic force of the No. 2 spring 27, the No. 2 spring 27 can drive the push block 21 to move downward, so that the push block 21 is separated from the limiter 19, and the copper tube can enter the interior of the cavity 16. Under the action of the mold core 17, the copper tube can be stretched into a suitable shape. A pulling mechanism is provided on the side of the mold shell 15 away from the supporting plate 2, and the pulling mechanism can pull the formed copper tube, which is beneficial to improve the efficiency of copper tube stretching.

[0042] The mold core 17 is movably inserted into the mold shell 15, so that the mold core 17 can be replaced as needed, which is beneficial to improving the application range of the device.
