Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, specifically a cutting and cleaning device. Background Technology

[0002] PE pipe is a type of pipe made of polyethylene material. It has excellent corrosion resistance, flexibility, low temperature resistance, and fracture toughness, and is widely used in water supply, gas supply, industry, agriculture and other fields.

[0003] PE pipes are generally used for heat fusion connection. The principle of heat fusion connection is to press the mating surfaces of two PE pipes tightly against a heating tool to heat their flat end faces until they melt. After removing the heating tool, the two molten end faces are pressed together and held under pressure until the joint cools down, so that the two pipe sections are connected as a whole.

[0004] Before PE pipes are hot-melt butt-welded, the end face must be cut to ensure that the end face is flat, vertical and free of impurities, and to avoid oil stains affecting the welding quality. If the end face is not flat or the misalignment exceeds the standard, it may lead to welding failure or leakage at the joint. Existing flattening devices generally use milling cutters for on-site flattening operations. However, during the operation of milling cutters, it is impossible for humans to accurately control the precision of the cutter. High-precision devices are large in size and inconvenient to use on the construction site.

[0005] Therefore, a new type of device was designed that can perform smooth cutting operations, ensuring uniform and flat cuts, while also being practical and convenient for use on construction sites. Utility Model Content

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the clamping block moves under the action of the guide rod A to clamp and fix the pipe. The scale lines on the surface of the guide rod A ensure that the clamping block moves the same distance, so that the center of the rotating rod and the center of the pipe are in a straight line, ensuring that the pipe is subjected to uniform force. At the same time, it provides a stable fulcrum for the rotating rod, which facilitates the blade to perform flat cutting and ensures the accuracy of flat cutting.

[0017] 2.

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.

[0026] In this utility model:

[0027] Reference Figure 1-6 A cutting and cleaning device includes a connecting frame 1, characterized in that: both the upper and lower ends of the connecting frame 1 are fixed with insert plates 101, the surface of the insert plates 101 is provided with threaded holes 1011, the center of the connecting frame 1 is integrally provided with a rotating plate 102, and one side of the connecting frame 1 is provided with a clamp 2.

[0028] The clamp 2 is ring-shaped and is divided into two parts connected by connecting ears 202. The clamp 2 has symmetrical sockets 201 on its outer side. The shape of the insert plate 101 and the socket 201 are both arc-shaped and fit together. There are several threaded holes 1011, which are evenly distributed on the surface of the connecting frame 1. The surface of the socket 201 is provided with bolt connection holes, and the bolt connection holes correspond to the threads of the threaded holes 1011. When cutting, the insert plate 101 is inserted into the socket 201, and the connecting frame 1 is adjusted to a suitable position. The insert plate 101 and the socket 201 are fixed with bolts, which can provide a stable fulcrum for the rotating rod 4, making it easy for the blade to cut flat. The clamp 2 is provided with a clamping mechanism for connecting to the pipe, and the connecting frame 1 is provided with a cutting mechanism for cutting the pipe opening flat.

[0029] The clamping mechanism includes clamping block 3, lead screw A301 and guide rod A302;

[0030] The clamping block 2 has a clamping block 3 inside. A screw rod A301 is rotatably connected to the center of the back of the clamping block 3. Guide rods A302 are fixedly connected to the back of the clamping block 3 on both sides of the screw rod A301. There are 4 clamping mechanisms, which are evenly distributed inside the clamping block 2. Both the screw rod A301 and the guide rod A302 extend out of the clamping block 2. The screw rod A301 and the clamping block 2 are connected by threads, and the guide rod A302 and the clamping block 2 are connected by sliding. The guide rod A302 has scale lines on its surface. The inner surface of the clamping block 3 is covered with an anti-slip rubber layer. By rotating the screw rod A301, the clamping block 3 moves under the action of the guide rod A302, thereby clamping the pipe. The scale lines on the surface of the guide rod A302 ensure that the clamping block 3 moves the same distance. This ensures that the center of the rotating rod 4 and the center of the pipe are in a straight line, ensuring that the pipe is subjected to uniform force. The anti-slip rubber layer on the inner surface of the clamping block 3 can better fit the pipe and has a certain degree of anti-slip properties.

[0031] The cutting mechanism includes a rotating rod 4, a rotating handle 401, an extension plate 5, a guide rod B501, a lead screw B502, a tool holder 6, and a blade 7;

[0032] The rotating disk 102 is rotatably connected to a rotating rod 4. One end of the rotating rod 4 is slidably connected to a rotating handle 401. The other end of the rotating rod 4 is fixed to both sides of an extension plate 5. A tool holder 6 is set inside the extension plate 5. A lead screw B502 is rotatably connected to the middle of the back of the tool holder 6. Guide rods B501 are fixedly connected to both sides of the lead screw B502 on the back of the tool holder 6. A blade 7 is fixedly connected to the opening of the tool holder 6 by bolts.

[0033] Furthermore, both the guide rod B501 and the lead screw B502 extend into extension plates 5, and the guide rod B501 and the extension plate 5 are slidably connected, while the lead screw B502 and the extension plate 5 are threadedly connected. The guide rod B501 has scale lines on its surface. By rotating the lead screw B502, the tool holder 6 can be moved and adjusted under the action of the guide rod B501. The scale lines on the surface of the guide rod B501 can ensure that the tool holders 6 on both sides are at the same horizontal position, thus improving the cutting efficiency.

[0034] Furthermore, the angle between the two extension plates 5 and the pipe opening is 30 degrees, and the two extension plates 5 are centrally symmetrical. The angle between the extension plates 5 and the pipe opening makes the blade 7 form a smaller angle with the pipe opening, which can save more effort during cutting. The two blades 7 are centrally symmetrical, so that the pipe can be cut in a circular motion.

[0035] Working principle: First, the clamp 2 is placed on the outside of the pipe, and the connecting ears 202 on both sides of the clamp 2 are fixed with bolts. Then, by rotating the screw A301, the clamping block 3 moves under the action of the guide rod A302, thereby clamping and fixing the pipe. The scale lines on the surface of the guide rod A302 ensure that the clamping block 3 moves the same distance, thus making the center of the rotating rod 4 and the center of the pipe a straight line, ensuring that the pipe is subjected to uniform force. The anti-slip rubber layer on the inner surface of the clamping block 3 can better fit the pipe and has a certain degree of anti-slip. Next, the insert plate 101 is inserted into the socket 201, and the connecting bracket 1 is adjusted to a suitable position. By fixing the insert plate 101 and the socket 201 with bolts, a stable fulcrum is provided for the rotating rod 4, which facilitates the cutting operation of the blade. Then, by rotating the lead screw B502, the blade holder 6 is moved and adjusted under the action of the guide rod B501, thereby adjusting the blade 7 to the appropriate position. The scale lines on the surface of the guide rod B501 can make the two blade holders 6 at the same horizontal position. Finally, by manually rotating the rotating handle 401, the rotating rod 4 is rotated, which drives the blade 7 to rotate in a circle, thereby cutting the pipe opening flat and making the pipe opening clean and flat, so that the pipe opening can be more easily welded.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
