Description

Technical Field

[0001] The invention relates to the technical field of pipe cutting, in particular to a pipe production cutting device. Background Art

[0002] Pipeline laying: The main lines of water supply, drainage, heating, and gas supply in cities and long-distance oil and gas pipelines are mostly laid underground. When transporting pipelines, they usually need to be cut into suitable lengths to avoid trouble caused by pipelines being too long. Existing pipe cutting machines can achieve normal cutting of pipelines, so that the pipelines can be cut according to the required specifications.

[0003] A Chinese patent discloses a pipe cutting machine (publication number: CN111250776A). The patent can realize the cooperation of the mobile clamping block and the fixed clamping block to clamp the pipe by turning the handle, and at the same time realize the rotating motor to drive the circular cutter to cut the pipe. By continuing to select the handle, the fixed clamping block and the mobile clamping block can not clamp the pipe, the cutting length of the pipe on the next side can be adjusted, and the rotating motor drives the circular cutter to reset. However, when the device cuts the pipe, since the cutting needs to completely penetrate the pipe to completely cut the pipe, the required cutting disc and the space required for cutting are relatively large, which causes the non-cutting surface of the cutting disc to contact the pipe during cutting, resulting in burrs on the cutting surface.

[0028] A support sleeve 21 is provided through one side of the rotating ring 10, and sliding grooves 22 are provided on both sides of the inner wall of the support sleeve 21.

When the pipe moves to a certain distance, the pull rod 26 is rotated to adjust the height of the cylinder 27, and then the cylinder 27 is extended by rotating the starter, so that the connecting plate 28 slides in the side groove 29, thereby pushing the rotating plate 31 to rotate on the inner surface of the rotating groove 30, and further driving the push plate 33 to slide on the inner surface of the inner groove 32. At this time, the positioning block 34 clamps the pipe, and then the rotating screw is rotated. The nut 20, with the cooperation of the sliding protrusion 23 and the sliding groove 22, can make the threaded rod 19 move upward, so that the fixed block 15 moves to the side close to the pipe. At the same time, the cutting motor 16 is started to rotate, thereby driving the cutting disc 18 in the installation groove 17 to rotate, and further driving the cutting disc 18 to rotate to cut the pipe. Then the servo motor 13 on the connecting rod 7 is started to rotate, thereby driving the driving gear 14 to rotate. Through the meshing relationship between the driving gear 14 and the gear teeth 11 in the through cavity 12, the rotating ring 10 is rotated in the two sliding sleeves 9, further driving the cutting disc 18 to rotate around the pipe, thereby completing the cutting of the pipe.
