Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a pipe cutting tool. Background Technology

[0002] Plastic pipes are generally made from synthetic resin, specifically polyester, with the addition of stabilizers, lubricants, and plasticizers, through extrusion processing in a pipe-making machine. Because the inside of the pipe cannot be directly observed during production, a pipe-cutting fixture is needed to cut it open and determine if there are any internal defects. Traditional pipe-cutting fixtures mainly include a frame, guide rails, slides, cylinders, motors, and cutting tools. Through the coordinated action of these components, the plastic pipe is cut. However, traditional pipe-cutting fixtures have some problems:

[0003] ① Traditional pipe cutting tools are large in size and heavy in weight. When they need to be moved frequently or transferred between different workplaces, this inconvenience will greatly increase the difficulty and cost of transportation and installation.

[0004] ② Because traditional pipe cutting tooling has a complex structure and the components are tightly connected, once a fault occurs or repair is needed, it often requires professional technicians and tools to disassemble and repair it. This not only increases the difficulty and cost of repair, but may also affect the production schedule due to the long repair cycle.

[0005] ③ In traditional plastic pipe cutting fixtures, the cutting tools (such as disc cutters) are usually fixed to the motor output shaft, and replacement requires disassembling multiple parts, making the operation complex. Tool wear is inevitable, and the complex replacement process not only increases the difficulty of operation but may also damage other parts due to improper operation. In addition, if the disc cutter is specifically designed, the corresponding replacement part must be found, increasing the difficulty of selecting and replacing parts. Utility Model Content

The projection of the blade mounting groove on the inner wall of the cavity along the height direction of the tooling body is located in the middle cavity. Taking the surface where the blade mounting groove is located on the tooling body as the top surface of the tooling body, the bottom wall height of the front cavity and the bottom wall height of the rear cavity are respectively greater than or equal to the bottom wall height of the middle cavity.

[0010] Alternatively, the bottom wall of the middle section of the tube may be an inclined surface with the front end lower than the rear end.

[0011] Optionally, the pipe cutting tool further includes a hollow cylindrical metal guide sleeve, which is interference-fitted to the inner wall of the front section of the pipe.

[0012] In an optional technical solution of this utility model embodiment, the surface where the blade mounting groove is located on the tooling body is taken as the top surface of the tooling body. A threaded hole communicating with the blade mounting groove is also provided on the top surface of the tooling body. The diameter of the threaded hole is larger than the width of the blade mounting groove. The blade fixing member is threadedly installed in the threaded hole to press and fix the cutting blade inside the blade mounting groove.

[0013] Alternatively, the blade retainer may be a screw or bolt.

[0014] Optionally, the threaded hole is located at the middle of the blade mounting groove along its length.

[0015] In an optional technical solution of this utility model embodiment, the tooling body is a metal block.

[0016] In an optional technical solution of this utility model embodiment, the pipe cutting tool further includes a clamp, which is used to clamp the tool body to the workbench panel.

Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] This embodiment provides a pipe-splitting tool, as shown in the following example. Figures 1 to 3 The pipe-cutting fixture includes a fixture body 100, a cutting blade 2, and a blade fixing member 3. The fixture body 100 has a height direction and a front-back direction. Inside the fixture body 100, there is a cavity 110 that runs through the fixture body 100 along the front-back direction. On one end surface of the fixture body 100 in the height direction, there is also a blade mounting groove 120 that connects to the cavity 110. The length direction of the blade mounting groove 120 extends along the front-back direction of the fixture body 100. The cutting blade 2 is fixed inside the blade mounting groove 120 by the blade fixing member 3, and the cutting blade 2 runs through the cavity 110 along the longitudinal direction of the fixture body 100.

[0034] The tube-splitting tool provided in this embodiment is used as follows:

[0035] according to Figures 1 to 3 The structure shown utilizes the blade retainer 3 to insert or fix the cutting blade 2 inside the blade mounting slot 120. For example... Figure 6 As shown, the fixture body 100 is fixed on the workbench. Then, the plastic tube 300 to be cut is inserted from the front end of the fixture body 100 into the cavity 110 of the fixture body 100. The plastic tube 300 is pushed further back, and the cutting blade 2 can cut the plastic tube 300. The cut plastic tube 300 is taken out from the outlet of the cavity 110 at the rear end of the fixture body 100. The above work of pushing the plastic tube 300 into the cavity 110 and taking out the cut plastic tube 300 from the cavity 110 is completed manually by the workers or with the help of tools. After the cut plastic tube 300 is taken out, it can be further manually trimmed.

[0036] When the cutting blade 2 becomes dull, chipped, or damaged, it should be replaced promptly to avoid affecting the cutting effect and efficiency. The replacement method is as follows: use appropriate tools to loosen the blade retainer 3 and remove the old cutting blade 2 from the blade mounting slot 120 of the fixture body 100. Place the new cutting blade 2 into the blade mounting slot 120 according to the installation position and direction of the old cutting blade 2, ensuring that the new cutting blade 2 fits tightly with other parts of the fixture body 100. Re-secure the blade retainer 3 and fix the new cutting blade 2 in the blade mounting slot 120 of the fixture body 100.

[0037] Compared to traditional pipe-cutting fixtures, the pipe-cutting fixture structure provided in this embodiment has at least the following advantages: ① High portability: The entire fixture structure is compact and lightweight, making it easy to carry to the field for operation; ② Simple operation: No professional training is required to quickly get started, greatly reducing the barrier to entry; ③ Low cost: Compared to traditional large pipe-cutting fixtures, the pipe-cutting fixture provided in this embodiment has a lower cost and is more suitable for small-batch and field operation needs; ④ Easy to replace cutting tools, and the cutting tools have a simple blade structure, making them easier to select and replace, reducing maintenance difficulty and cost.

[0038] Continue to refer to Figures 1 to 3 In an optional embodiment of this example, along the front-rear direction of the tooling body 100, the cavity 110 includes a front cavity 111, a middle cavity 112, and a rear cavity 113. The projection of the blade mounting groove 120 on the inner wall of the cavity 110 along the height direction of the tooling body 100 is located in the middle cavity 112. Taking the surface where the blade mounting groove 120 is located on the tooling body 100 as the top surface of the tooling body 100, the bottom wall height of the front cavity 111 and the bottom wall height of the rear cavity 113 are respectively greater than or equal to the bottom wall height of the middle cavity 112. Preferably, the bottom wall height of the front section cavity 111 and the bottom wall height of the rear section cavity 113 are greater than the bottom wall height of the middle section cavity 112. That is, the bottom wall of the middle section cavity 112, corresponding to the blade mounting groove 120, is lower than the front section cavity 111 and the rear section cavity 113. This can be achieved by the entire bottom wall of the middle section cavity 112 being lower than the front section cavity 111 and the rear section cavity 113, or by providing a groove on the bottom wall of the middle section cavity 112 that can accommodate the bottom edge of the cutting blade 2. This groove serves as a part that is lower than the front section cavity 111 and the rear section cavity 113. In this way, the bottom edge of the cutting blade 2 is accommodated by the bottom wall of the middle section cavity 112, allowing the cutting blade 2 to penetrate the middle section cavity 112 along the height direction of the tooling body 100, so as to cut through the plastic tube 300 radially. This avoids the phenomenon that the part of the plastic tube 300 that should have been cut still has some adhesion after being removed, requiring rework.

[0039] Furthermore, the bottom wall of the middle section cavity 112 is an inclined surface with the front end lower than the rear end. The bottom edge shape of the cutting blade 2 is correspondingly set to match the bottom wall of the middle section cavity 112 to facilitate the positioning of the cutting blade 2.

[0040] Continue to refer to Figures 1 to 3To ensure the straightness and stability of the cutting blade 2 during the cutting process, in an optional embodiment of this invention, the tube cutting fixture further includes a hollow cylindrical metal guide sleeve 4. The metal guide sleeve 4 is interference-fitted to the inner wall of the front section of the tube cavity 111. In use, the plastic tube 300 to be cut is pushed into the metal guide sleeve 4, and the metal guide sleeve 4 forms a guide channel. The inner diameter of the metal guide sleeve 4 matches the outer diameter of the plastic tube 300 to be cut, which serves to guide the plastic tube 300 into the cutting area and guide the plastic tube 300 to be cut along a predetermined trajectory.

[0041] Continue to refer to Figures 1 to 3 In an optional embodiment of this invention, the surface of the tooling body 100 containing the blade mounting groove 120 is taken as the top surface of the tooling body 100. A threaded hole communicating with the blade mounting groove 120 is also provided on the top surface of the tooling body 100. The diameter of the threaded hole is larger than the width of the blade mounting groove 120. The blade fixing member 3 is threaded into this threaded hole to press and fix the cutting blade 2 inside the blade mounting groove 120. During installation, it is necessary to ensure that the blade fixing member 3 is tightened in place to prevent the cutting blade 2 from moving or falling off during the cutting process. The blade fixing member 3 under this structure is easy to assemble and disassemble, and can effectively fix the cutting blade 2 to the tooling body 100.

[0042] In the above structure, the blade fixing member 3 may be, but is not limited to, a screw or bolt; in addition, preferably, the threaded hole is located in the middle of the blade mounting groove 120 in the length direction to further improve the reliability of fixing the cutting blade 2 and prevent the cutting blade 2 from deflecting during use.

[0043] For the tooling body 100 in this embodiment, it can be selected as a metal block structure to ensure its structural strength. Furthermore, it is preferred that the tooling body 100 has a rectangular or square shape to facilitate its fixation.

[0044] In addition, to ensure that the fixture body 100 is securely fixed to the worktable during use and to prevent the fixture body 100 from moving or shaking during the cutting process, refer to... Figure 4 , Figure 5 and Figure 6 In an optional embodiment of this example, the pipe cutting tool further includes a clamp 200, which is used to clamp the tool body 100 to the workbench panel.

[0045] Optionally, the fixture 200 adopts a G-shaped fixture 200, including an arc-shaped body 210 and a screw 220; the arc-shaped body 210 forms a clamping space for clamping the workbench panel and the fixture body 100. The screw 220 is threaded to one end of the arc-shaped body 210 and one end of the screw 220 extends into the clamping space to clamp the fixture body 100 to the workbench panel. The clamping force can be freely adjusted by the screw 220 in the G-shaped fixture 200 relative to the arc-shaped body 210 to stably clamp the fixture body 100. With the precise positioning between the fixture body 100 and the cutting blade 2, efficient and precise cutting of the plastic tube 300 can be achieved.

[0046] Finally, it should be noted that:

[0047] 1. The pipe cutting tool provided by this utility model is not only applicable to cutting plastic pipe 300, but can also be used to cut other cuttable pipes;

[0048] 2. The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments.
