The top block 28 then returns to its original position.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, a handle 11 is provided on one side of the turntable 2. A hard brush 12 is provided on the surface of the handle 11 near one edge. A lifting handle is provided on the top of the hard brush 12, which can be directly removed to clean other places. An inner ring 13 is provided at the center of the bottom of the inner cavity of the turntable 2. Several balls 14 are surrounded on the side of the inner ring 13.

[0030] Please refer to Figure 1 As shown, a support mold 3 is provided at the top of the base 1 near the edge, and a support foot 7 is provided at the bottom of the base 1 near the edge. The support foot 7 is flush with the bottom of the air cylinder 8.

[0031] Please refer to Figure 1 and Figure 2 As shown, the bottom of the fixed mold 4 is provided with a protruding plate that is fixed inside the fixed mold groove 15, and the fixing screw 16 passes through the center of the fixed mold 4 and the gasket 6.

[0032] Please refer to Figure 6As shown, the number of fixed pins 503 and the first spring 504 is two, and the shape of the fixed pin 503 and the pin hole 18 is the same.

[0033] As shown in Figure 1 and Figure 3 As shown, the number of dynamic mold holes 10 is 3, the fixed mold 4, the dynamic mold 5, the dynamic mold hole 10 and the handle 11 are arranged in a straight line.

[0034] As shown in Figure 1 , Figure 2 and Figure 4 As shown, the top block 28 is arranged in the middle of the inner ring 13, the top of the top block 28 is in the middle of the turntable 2, and the top of the turntable 2 is flat, and the fixed screw rod 16 and the fixed mold groove 15 are arranged on the top of the top block 28.

[0035] As shown in Figure 4 As shown, the number of second springs 25 is 4.

[0036] As shown in Figure 6 As shown, the screw rod 502 is immersed in the mold column 501, and the bottom of the screw rod 502 is conical.

[0037] The electrical components appearing in this article are all connected with the main controller and 220V mains, and the main controller can be a computer or other conventional known device that can be controlled.

[0038] In use, through the cooperation of the turntable 2, the ball 14 and the inner ring 13, the handle 11 is pushed to drive the turntable 2 to rotate, so that the inner wall of the turntable 2 interacts with the ball 14 on the outside of the inner ring 13, reducing the friction force and the force used by the artificial bending pipe, increasing the work efficiency.

[0039] Through the cooperation of the mold column 502, the first spring 504, the fixed pin 503, the screw rod 502 and the pin hole 18, after the dynamic mold 5 is inserted into the corresponding dynamic mold hole 10, the screw rod 502 is rotated to make the screw rod 502 press down, and the sharp head of the screw rod 502 will push the fixed pin 503 on both sides to make the fixed pin 503 inserted into the pin hole 18, so as to fix the dynamic mold 5, and then rotate the screw rod 502 to make the screw rod 502 rise, and the fixed pin 503 is not pressed by the screw rod 502, and is retracted to the original position under the force of the first spring 501, so that the position of the dynamic mold 2 is more convenient to adjust, and is more fixed, preventing loosening during bending.

[0040] When the pipe bender machine ends work, the pipe will be stuck in the mold because of the pipe bending. By pressing the pedal 9, the power arm 19 exerts an upward thrust on the power plate 21 through the slide cylinder 20, the power plate 21 pushes the piston 23 upward through the support rod 22, the piston 23 pushes the second movable air plate 31 to block the air inlet 30, and pushes the first movable air plate 26 away. Then the air enters the air chamber 27. After that, the second spring 25 pulls the power arm 19 back to the original position, and the piston 23 is also pulled back to the original position, which will suck the first movable air plate 26 to seal the air chamber 27, and suck the second movable air plate 31 to open the air inlet 30. By repeating the operation, the air chamber 27 is continuously filled with air. The excess air will lift the top block 28, change the position of the fixed mold 4, and make the pipe stuck in the mold be taken out. When the top block 28 is lifted to a certain height, the exhaust groove 29 will contact the space between the rotating disc 2 and the inner ring 13 to exhaust the air in the air chamber 27. The top block 28 is returned to the original position, which solves the problem of material sticking by stepping on the pedal, increases the functionality, improves the work efficiency, and is convenient for the user to operate.
