Description

Technical Field

[0001] This utility model relates to the technical field of pipe cutting devices, specifically a pipe cutting device for the production of corrosion-resistant pipes. Background Technology

[0002] Corrosion-resistant pipes (such as epoxy coal tar pitch and 3PE coated steel pipes) are widely used in petrochemical, municipal engineering, and other fields. Their production requires precise cutting of pipes of a fixed length. Existing cutting devices mostly use electric saw discs to cut pipes. While efficient at cutting smaller diameter pipes, they have significant drawbacks when dealing with larger diameter pipes (e.g., diameter ≥ 0.8 meters). When cutting larger diameter pipes, the diameter of the electric saw disc needs to be more than twice the diameter of the pipe to be cut. Large-sized electric saw discs are very expensive and require high-power drive motors. Insufficient drive motor torque can cause the electric saw disc to jam or result in off-center cutting. After off-center cutting, multiple recalibrations are required, leading to low efficiency. Utility Model Content

[0022] Please refer to Figures 1 to 4 The present invention relates to a pipe cutting device for the production of anti-corrosion pipes, comprising a base plate 100, a support assembly, and a clamping assembly.

[0023] The base plate 100 is a rectangular plate, and the support assembly includes multiple support seats 200. Two support rollers 210 are rotatably arranged on each support seat 200, and the tube body 300 to be cut is supported on the support rollers 210. Specifically, in this embodiment, the support assembly includes four support seats 200, and the preset cutting line of the tube body 300 to be cut is located between the two support seats 200 in the middle. This allows each section of the tube body to be cut to be supported on the two support seats 200 after it is cut into two sections.

[0024] The clamping assembly includes at least one set of clamping rods 400. Each set of clamping rods 400 includes two clamping rods 400 respectively disposed on both sides of the tube body 300 to be cut. Each clamping rod 400 is provided with a telescopic mechanism at its upper end. The end of the telescopic mechanism is provided with a rotating pressure roller 412, which is rotatably disposed at the end of the telescopic mechanism. In this embodiment, there are two sets of clamping assemblies, and the preset cutting line of the tube body 300 to be cut is located between the two clamping assemblies.

[0025] The base plate 100 has a slide rail groove 101 in the middle. The preset cutting line of the tube body 300 to be cut is aligned with the slide rail groove 101. A cutting sliding plate 600 and a driving sliding plate 500 are slidably arranged in the slide rail groove 101. Two sliding driving mechanisms are respectively provided at both ends of the slide rail groove 101. The two sliding driving mechanisms are respectively connected to the cutting sliding plate 600 and the driving sliding plate 500. A cutting electric saw 602 is fixedly mounted on the cutting sliding plate 600. A driving mounting seat is fixedly mounted on the driving sliding plate 500. A rotating driving motor 502 and a rotating driving roller 501 are provided on the driving mounting seat. The rotating driving motor 502 is fixed on the driving mounting seat. The rotating driving roller 501 is fixedly connected to the output shaft of the rotating driving motor 502.

[0026] Specifically, each sliding drive mechanism includes a screw mounting base 800 and a drive screw 700. Both the cutting sliding plate 600 and the drive sliding plate 500 have through threaded holes. The two screw mounting bases 800 are fixedly mounted at both ends of the slide rail groove 101. Each screw mounting base 800 has a rotating mounting hole, and each drive screw 700 is rotatably mounted in one of these holes. The two drive screws 700 pass through the threaded holes in the cutting sliding plate 600 and the drive sliding plate 500, respectively. Each end of the two drive screws 700 has a drive handwheel 701. Rotating one of the drive screws 700 drives the sliding plate connected to it (i.e., the cutting sliding plate 600 or the drive sliding plate 500) to move along the slide rail groove 101. When the pipe body 300 is to be cut, the two sliding drive mechanisms drive the cutting sliding plate 600 and the drive sliding plate 500 to move toward the pipe body 300 to be cut, respectively. After the cutting sliding plate 600 approaches the pipe body 300 to be cut, the cutting electric saw 602 can cut a portion of the predetermined cutting line of the pipe body 300 to be cut (by controlling the feed of the cutting electric saw 602, the saw disc cuts through the side wall of the pipe body 300 to be cut). After the drive mounting base approaches the pipe body 300 to be cut, the rotating drive roller 501 presses against the outer wall of the pipe body 300 to be cut. The rotating drive motor 502 drives the rotating drive roller 501 to rotate. In this way, the rotating drive roller 501 can drive the pipe body 300 to be cut to rotate through friction, so that the cutting electric saw 602 continuously cuts along the predetermined cutting line, thereby cutting the pipe body into two sections.

[0027] In a preferred embodiment, each support base 200 has two mounting plates, with a mounting groove formed between the two mounting plates. The support roller 210 is axially provided with a support shaft 413, and both ends of the support shaft 413 are rotatably mounted on the two mounting plates. This allows the support roller 210 to be rotatably mounted on the support base 200.

[0028] Each mounting clamp is provided with a clearance groove 201 in the middle. All clearance grooves 201 in the middle of the mounting clamp are aligned with each other. The clearance grooves 201 prevent the lower part of the tube body 300 to be cut from contacting the mounting clamp, ensuring that the tube body 300 to be cut is fully supported on the support roller 210.

[0029] In a preferred embodiment, the telescopic mechanism is a telescopic cylinder 410. A rotating bushing 411 is fixedly provided at the end of the telescopic shaft of the telescopic cylinder 410. A rotating pressure shaft is axially provided on the rotating pressure roller 412, and the rotating pressure shaft is rotatably disposed within the rotating bushing 411. A mounting plate 401 is provided at the top of the clamping support rod 400, and the telescopic cylinder 410 is fixed on the mounting plate 401. The telescopic cylinder 410 is inclined. When the telescopic shaft of the telescopic cylinder 410 extends, the rotating pressure roller 412 presses against the surface of the tube body 300 to be cut, and the rotating pressure roller 412 can rotate relative to the tube body 300 to be cut.

[0030] In a preferred embodiment, the cutting motor 603 includes a chainsaw mounting base 601, a chainsaw disc 602, and the cutting motor 603 itself. The chainsaw mounting base 601 is fixed to the cutting sliding plate 600, the cutting motor 603 is fixed to the chainsaw mounting base 601, and the chainsaw disc 602 is fixedly connected to the output shaft of the cutting motor 603. The axis of the tube to be cut 300 is perpendicular to the chainsaw disc 602. When the cutting motor 603 is started, it drives the chainsaw disc 602 to rotate. After the chainsaw mounting base 601 is fed to a predetermined position, the chainsaw disc 602 can vertically cut the tube to be cut 300.

[0031] In a preferred embodiment, the chainsaw mounting base 601 and the drive mounting base are respectively fixedly connected to the cutting sliding plate 600 and the drive sliding plate 500 by two fixed connecting plates. The fixed connecting plates are used to fix the chainsaw mounting base 601 and the drive mounting base at a predetermined height.

[0032] The working process of the pipe cutting device for producing anti-corrosion pipes according to this utility model is as follows: The pipe body 300 to be cut is hoisted onto the support base 200 of the cutting device by a hoisting device, so that the preset cutting line of the pipe body 300 to be cut is aligned with the saw disc 602 of the cutting electric saw; the telescopic cylinder 410 is activated, so that the telescopic shaft of the telescopic cylinder 410 extends, and the telescopic shaft of the telescopic cylinder 410 presses the rotating pressure roller 412 against the surface of the pipe body 300 to be cut, so that the pipe body 300 to be cut is firmly and rotatably supported on the support base 200; the handwheel is turned. 701, drive the drive mounting base to move toward the tube body 300 to be cut, so that the rotating drive roller 501 is pressed against the surface of the tube body 300 to be cut, start the rotating drive motor 502, drive the rotating drive roller 501 to drive the tube body 300 to be cut to rotate at low speed; start the cutting electric saw 602; crank the other handwheel 701 to adjust the position of the cutting sliding plate 600, so that the cutting electric saw 602 is aligned with the preset cutting line to cut the tube body 300 to be cut. The surface of the tube body 300 to be cut is continuously cut by the saw blade during rotation until the tube body is divided into two sections.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
