[0002] A pipe cutting device is a tool used to cut metal, plastic, fiberglass and other pipes. It usually consists of an electric motor or pneumatic drive system, a cutting head and a control system. When using a pipe cutting device, the operator needs to make correct settings and adjustments based on the cutting target and pipe material. Then, use the control system to start the cutting head and adjust the cutting speed and depth as needed. When the cutting head rotates, the blade will cut the pipe through friction and cutting force to complete the cutting task.

The front side of the lifting rod 8 is fixedly connected to the rear side of the support seat 5, and a rotating groove 9 is opened inside the support seat 5 and the lifting seat 6. The inside of the rotating groove 9 is rotatably connected with a rotating ball 10 through an axle pin. The lifting and positioning mechanism is fixedly connected to the top of the lifting seat 6, and the pipe that needs to be annularly cut is placed on the inner side of the support seat 5 and the lifting seat 6, so that the support seat 5 and the lifting seat 6 can clamp and support the pipe. Since the rotating groove 9 and the rotating ball 10 are connected by an axle pin, the rotating ball 10 can only rotate back and forth. At the same time, the rotating groove 9 cooperates with the rotating ball 10 to adjust the pipe and the support seat 5 and the lifting seat The lowering seat 6 is in rotational contact with each other, which is convenient for the staff to rotate the pipe and perform circular cutting on the pipe through the cutting knife 2. The lifting and positioning mechanism includes a lifting platform 11, an active groove 12, a positioning frame 13 and a positioning groove 14. The lifting platform 11 is fixedly connected to the top of the lifting seat 6, and the active groove 12 is opened inside the lifting platform 11.

One end of the spring 16 is fixedly connected to the inner wall of the spring groove 15, and the other end of the spring 16 is fixedly connected to the surface of the positioning frame 13. When the positioning frame 13 is used in conjunction with the lifting seat 6 and the lifting rod 8 through the positioning groove 14, a backward thrust can be applied to the positioning frame 13 to avoid the positioning frame 13 from being separated from the positioning groove 14 during use, thereby improving the positioning stability of the positioning frame 13. A lifting groove 17 connected to the positioning groove 14 is provided on the rear side of the lifting rod 8. A lifting bar 18 is movably connected inside the lifting groove 17, and the bottom of the lifting groove 17 passes through the bottom of the lifting rod 8. When the rack 20 cooperates with the tooth groove 19, the rack 20 and the lifting rod 8 can be movably connected to each other, thereby avoiding the situation where the rack 20 is difficult to connect with the lifting rod 8 when in use, thereby improving the connection flexibility between the rack 20 and the lifting rod 8.

When the spring 16 is used in conjunction with the positioning frame 13, the backward thrust of the positioning frame 13 can be converted into a downward thrust, so that the lifting bar 18 drives the rack 20 to enter the magnetic groove, thereby avoiding the situation where it is difficult to push the rack 20 into the tooth groove 19 when the lifting bar 18 is in use, thereby improving the downward pushing effect of the lifting bar 18.

[0036] Reference Figure 3-Figure 4 In a preferred embodiment, a reset port 23 is provided at the bottom of the lifting bar 18, and a reset plate 24 is movably connected inside the reset port 23.

One end of the reset spring 25 is fixedly connected to the inner wall of the reset port 23, and the other end of the reset spring 25 is fixedly connected to the surface of the reset plate 24. After the push seat 22 is separated from the push groove 21, an upward reset thrust can be applied to the lifting bar 18, so that the lifting bar 18 is lifted and drives the rack 20 to be separated from the tooth groove 19, thereby avoiding the situation that the lifting bar 18 is difficult to rise and reset when in use, thereby improving the reset convenience of the lifting bar 18. Slide grooves 26 are provided on both sides of the top of the fixed seat 4, and a slide bar 27 is movably connected inside the slide groove 26. The top of the slide bar 27 is fixedly connected to the bottom of the support seat 5. When the fixed seat 4 is used in conjunction with the support seat 5, the support seat 5 and the fixed seat 4 can be slidably connected to avoid the situation that the support seat 5 is separated from the fixed seat 4 when in use, thereby improving the use stability of the support seat 5.

[0037] Specifically, the working process or working principle of the pipe cutting device is as follows: when in use, the pipe is placed on the top of the support seat 5 by hand, and then the positioning frame 13 is moved to the rear side by hand to disengage from the positioning groove 14 and drive the push seat 22 to disengage from the push groove 21. During this process, the reset spring 25 applies an upward reset thrust to the lifting bar 18 through the reset plate 24 and the reset port 23, and drives the rack 20 to disengage from the tooth groove 19. At the same time, the spring 16 is affected by the forward movement force of the positioning frame 13 and contracts. Subsequently, the lifting seat 6 is moved downward and contacts the pipe on the top of the support seat 5 through the rotating groove 9 and the rotating ball 10. At this time, the lifting sleeve 7 cooperates with the lifting rod 8 to lift and connect the lifting seat 6 and the support seat 5, and cooperates with the support seat 5 to clamp and support the pipe, and then moves the pipe to the rear side to contact the cutting knife 2 to cut the pipe. At this time, the slide bar 27 follows the support seat 5 to move inside the slide groove 26 to support The seat 5 and the fixed seat 4 are slidably connected with each other, and then, the spring 16 held by the positioning frame 13 is released to apply a backward thrust to the positioning frame 13, so that the positioning frame 13 enters the positioning groove 14 to insert and position the lifting seat 6 and the lifting rod 8, and drives the pushing seat 22 to enter the pushing groove 21. Since the pushing groove 21 and the pushing seat 22 are in contact with each other at an inclined surface, when the pushing seat 22 enters the pushing groove 21, the lifting bar 18 is affected by the thrust of the pushing seat 22 and the pushing groove 21 to move downward and drive the rack 20 to enter the tooth groove 19, so that the rack 20 cooperates with the lifting bar 18 and the lifting rod 8 to perform a card connection and positioning work between the support seat 5 and the fixed seat 4. Subsequently, the staff applies a rotating force to the pipe between the support seat 5 and the lifting seat 6, so that the cutting knife 2 performs an annular cutting work on the pipe. At this time, the rotating groove 9 cooperates with the rotating ball 10 to perform a rotational connection work between the pipe and the support seat 5 and the lifting seat 6.

[0038] It should be noted that the cutting machine 1 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
