Description

Technical Field

[0001] This utility model belongs to the field of pipe processing technology, and specifically relates to a cutting device for pipe processing. Background Technology

[0002] MPP power conduit, also known as MPP power cable protection conduit, is a piping system used for the protection and laying of power cables. MPP power conduit is mainly made of modified polypropylene, a specially treated polypropylene material with a variety of excellent properties, giving MPP power conduit good insulation performance. It is suitable for the protection and laying of power cables and can maintain stable performance in high-temperature environments, ensuring the safe use of power cables.

[0003] A search revealed a Chinese utility model patent application with patent publication number CN222494447U, which discloses a cutting device for MPP power pipes. The device includes a worktable, a placement platform on the upper left side of the worktable, a control switch on the upper left side of the worktable, support legs fixedly connected around the lower end of the worktable, and locking wheels fixedly connected to the lower ends of the support legs. A material collection mechanism is detachably connected to the front end of the worktable. The material collection mechanism allows the device to collect the cut pipe waste in a centralized manner, facilitating subsequent cleaning by operators and preventing the accumulation of waste above the device.

[0004] Regarding the aforementioned technologies, the cutting device does not provide ideal fixation for the MPP power pipe, which easily leads to positional deviation, poor cutting accuracy, and low cutting quality. Therefore, there is an urgent need to design a pipe processing cutting device to address these issues. Utility Model Content

[0036] In this embodiment: the limiting mechanism includes a fixed cylinder 501 fixedly mounted on a mounting plate 401. At least one set of first frames 503 are movably mounted and correspondingly arranged on the fixed cylinder 501. A first limiting pressure roller 505 is rotatably mounted on the first frame 503. The first frame 503 is connected to a second electric telescopic rod 502 to drive the first limiting pressure roller 505 to move towards the center of the fixed cylinder 501. A second gantry 506 is fixedly mounted on the other side of the mounting plate 401. A limiting rotation assembly is movably mounted inside the second gantry 506. A second spring 507 is fixedly mounted between the limiting rotation assembly and the second gantry 506. The limiting rotation assembly includes a second frame 508 fixedly mounted inside the second gantry 506. A second limiting pressure roller 509 is rotatably mounted on the second frame 508. An MPP tube body 510 is pressed onto the outer surfaces of the first limiting pressure roller 505 and the second limiting pressure roller 509.

[0037] Working principle: In use, the MPP tube body 510 is first supported by the trapezoidal support platform 2051 by activating the first electric lifting rod 205. The MPP tube body 510 is then placed horizontally through the outer surface of the fixed frustum 206, the clamping part 408, the first limiting pressure roller 505, and the second limiting pressure roller 509. The forward and reverse motor 4031 is then activated, driving the second driving pinion 403 to rotate, which in turn drives the second large gear 404 to rotate at a certain angle. The mounting shaft 4041 drives the crank 405 to move. The guide groove 406 slides along the limiting member 407, causing the clamping part 408 at the end of the crank 405 to move towards the center of the driven turntable 402, reducing the clamping space. The clamping part 408 provides a center-to-center clamping force to the MPP tube body 510. At this time, the limiting members 407 at both ends and the middle of the crank 405, the second large gear 404, the driven turntable 402, and the crank 405 rotate as a whole. Moreover, as the whole continues to rotate, the clamping part 408 clamps the MPP tube body 510 more tightly. Simultaneously, the second electric telescopic rod 502 is activated, pushing the first frame 503 and the first limiting pressure roller 505 to move and cooperate with each other, so that the four sets of first limiting pressure rollers 505 simultaneously clamp the outer surface of the MPP tube body 510. One end of the MPP tube body 510 is positioned by the second limiting pressure roller 509. The second motor 307 is activated to drive the helical gear 306 to rotate and mesh with the rack 303, driving the support frame 304 to move up and down on the outer surface of the connecting platform 302. At the same time, the cutting blade 305 is adjusted to engage with the MPP tube body. When the outer surfaces of the MPP tube body 510 come into contact with each other, the drive motor 209 is started to drive the first active pinion 208 to rotate, and meshes with the first large gear 207 and the hollow rotating frustum 2061 to rotate, so that the cutting blade 305 fixedly installed in the inner ring of the hollow rotating frustum 2061 rotates and cuts the outer surface of the MPP tube body 510 by the cutting blade 305. After the MPP tube body 510 is cut, the cut MPP tube body 510 can be removed and replaced with the next MPP tube body 510 to be cut.
