[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] Please see Figures 1-4 This embodiment provides a large-diameter PE plastic pipe cutting device, including:
[0038] Pipe 10 is the object to be cut by the device. When the cut surface of pipe 10 is perpendicular to the axis of pipe 10, the plane cut by the device is also perpendicular to the axis of pipe 10.
[0039] The fixing mechanism 20 is set on the cut surface of the pipe 10 to fix the device to the surface of the pipe 10 and assist the device in making a flat cut of the pipe 10.
[0040] The cutting mechanism 30 is located on the end of the pipe 10 away from the cutting surface of the pipe 10 and is connected to the fixing mechanism 20. Under the drive of the fixing mechanism 20, it performs circumferential cutting on the pipe 10.
[0041] Specifically, the fixing mechanism 20 includes:
[0042] The fixed storage compartment 21 is set above the cut surface of the pipe 10 to store the fixed rod 22, thereby adapting to pipes 10 of different diameters;
[0043] A fixing rod 22 is installed at the telescopic end of the fixed storage compartment 21, which is the end where the fixing rod 22 enters the fixed storage compartment 21; the fixing rod 22 drives the roller 24 and the connecting rod 25 to slide inside the fixed storage compartment 21, thereby adapting to pipes 10 of different diameters;
[0044] A fixing knob 23 is located on the top of the fixing storage compartment 21. When the fixing knob 23 is tightened, it enters the fixing storage compartment 21 and presses against the fixing rod 22, thereby fixing the fixing rod 22.
[0045] Roller 24 is located below the fixed rod 22 and contacts the cut surface of pipe 10. Roller 24 moves on the cut surface of pipe 10, thereby driving the entire device to rotate on the surface of pipe 10 to complete the circumferential cutting of pipe 10.
[0046] The connecting rod 25 is set on the fixed rod 22 at one end away from the fixed storage compartment 21 and is located on the side of the pipe 10. It connects the fixing mechanism 20 and the cutting mechanism 30 together. When the fixing mechanism 20 rotates, the cutting mechanism 30 is driven by the fixing mechanism 20 to rotate at one end.
[0047] A handle 26 is set on the connecting rod 25 near the fixed storage compartment 21. Specifically, the end of the connecting rod 25 near the fixed storage compartment 21 is the end near the operator. The operator holds the handle 26 and squeezes the device to ensure that the roller 24 moves in close contact with the cut surface of the pipe 10 while driving the device to rotate and cut the pipe 10.
[0048] Specifically, the cutting mechanism 30 includes:
[0049] The tool magazine 31 is located on the connecting rod 25 at one end away from the fixed storage compartment 21. Specifically, the end of the connecting rod 25 away from the fixed storage compartment 21 is the cutting position of the cutting tool 32 on the pipe 10, and the cutting tool 32 is stored there.
[0050] The cutting tool 32 is located inside the tool magazine 31 and makes rotational contact with the pipe 10 to complete the cutting of the pipe 10;
[0051] The tool feed knob 33 is located on the top of the tool magazine 31 and is connected to the cutting tool 32. When the tool feed knob 33 is tightened, the cutting tool 32 descends and feeds the pipe 10 step by step, continuously cutting the pipe 10 until the pipe 10 is completely cut open.
[0052] Cutting auxiliary wheels 34 are arranged on both sides of the tool magazine 31 to help the tool magazine 31 move on the surface of the pipe 10;
[0053] The locking chamber 35 is located at the storage end of the tool chamber 31 and stores the locking strip 36.
[0054] Locking bar 36 is set at the connecting end of tool magazine 31 and is stored inside locking magazine 35, connecting the tool magazine 31 end to end to surround pipe 10.
[0055] The locking knob 37 is located above the locking chamber 35. When the locking knob 37 is tightened, it enters the locking chamber 35 and presses the locking strip 36, thereby fixing the locking strip 36.
[0056] Specifically, several rollers 24 are arranged on the same plane to ensure that the plane in which the rollers 24 are located is perpendicular to the axis of the pipe 10, thereby ensuring that the rollers 24 can move in contact with the cut surface of the pipe 10 that is perpendicular to the axis of the pipe 10.
[0057] Specifically, the locking strip 36 is made of a flexible material with toughness, which helps the tool magazine 31 fit against the surface of the pipe 10, so that the cutting mechanism 30 fits tightly against the pipe 10.
[0058] Specifically, the cutting tool 32, the tool magazine 31, and the cutting auxiliary wheel 34 are parallel to the plane where the rollers 24 are located. When the rollers 24 move on the cutting surface of the pipe 10, the plane cut by the cutting tool 32 under the drive of the rollers 24 is parallel to the cutting surface of the pipe 10.
[0059] When using:
[0060] This device achieves a smooth cut of the pipe 10, based on the fact that the cut surface of the pipe 10 is perpendicular to the axis of the pipe 10.
[0061] The staff pulled the fixing rod 22 of the fixing mechanism 20 out of the fixed storage compartment 21, and the cutting mechanism 30 increased in size as the fixing mechanism 20 increased under the drive of the connecting rod 25.
[0062] The operator places the device onto the surface of pipe 10. The operator then retracts the connecting rod 25 into the fixed storage compartment 21 until the roller 24 aligns with the cut surface of pipe 10, ensuring that pipe 10 is aligned with the groove of roller 24 to prevent it from slipping out. The tool compartment 31 of the cutting mechanism 30 moves together with the fixing rod 22 via the connecting rod 25. The locking strip 36 is retracted into the locking compartment 35. When pipe 10 is aligned with the groove of roller 24, the cutting auxiliary wheel 34 contacts pipe 10. The fixing knob 23 on the top of the fixed storage compartment 21 and the locking knob 37 on the top of the tool compartment 31 are tightened, completing the fixation of the fixing rod 22 and the locking strip 36. At this point, the device is completely fixed to the surface of pipe 10.
[0063] Before starting to cut the pipe 10, adjust the feed knob of the cutting tool 32 so that the cutting tool 32 gradually approaches the pipe 10 until it contacts the pipe 10. After the cutting tool 32 contacts the pipe 10, the operator holds the handle 26 and squeezes the device to ensure that the roller 24 moves in close contact with the cutting surface of the pipe 10, while driving the device to rotate and cut the pipe 10.
[0064] After the cutting tool 32 completes one revolution on the surface of the pipe 10, the tool feed knob 33 is adjusted to increase the cutting progress of the tool on the pipe 10.
[0065] The staff continuously feeds the cutting tool 32 until the pipe 10 is separated.
[0066] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
