During the production of the rubber oil pipe, the rubber oil pipe needs to be cut. Therefore, the rubber oil pipe needs to be placed on the cutting device, and then the cutting mechanism is used to cut the oil pipe.

[0003] According to the Chinese patent with the publication number CN213888448U, a fixed-length cutting device for high and low pressure oil pipes is disclosed.

After the first threaded column 20 moves downward, it can drive the first pressing plate 18 to move downward, and then press the other side of the rubber oil pipe;

[0046] Then rotate the threaded rod 901 so that one end of the threaded rod 901 approaches the cutting disc 14 but is not directly below the cutting disc 14. At this time, rotate the threaded shaft 907 again. The threaded shaft 907 will move and drive the push block 906 to move. When the push block 906 slides inside the movable cavity 902, it will push the push plate 905 to rotate, and the push plate 905 will push the support plate 904 to move, so that the outer wall of the support plate 904 can contact the inner wall of the oil pipe 5 to support the oil pipe 5, so that the cut part of the oil pipe 5 will not be completely flattened;

[0047] Then start the cylinder 23. When the cylinder 23 works, the piston rod can be extended, which will drive the mounting plate 12 to move downward, and then drive the motor 13 to move. Then start the motor 13. When the motor 13 works, it can drive the cutting disc 14 to rotate, so that the cutting disc 14 cuts the oil pipe 5.
