Description

Technical Field

[0001] This utility model relates to the field of pipeline engineering technology, and in particular to a cutting mold for pipeline insulation materials. Background Technology

[0002] When traditional pipe insulation construction reaches the pipe joint position (including L-shaped joint position and T-shaped joint position), workers often cut the joint shape of the pipe insulation material according to their own skills. Due to the limitations of their skills, they often cannot cut a perfect joint shape, resulting in poor cutting accuracy of the joint shape. This will eventually lead to an uneven and non-dense joint, increasing the difficulty of bonding or fixing, and also causing a decrease in insulation performance.

[0003] Chinese utility model patent CN207213509U discloses a heating, corrosion-resistant, and heat-insulating pipeline and its cutting device, including a pipe body and a shearing assembly. The pipe body includes a base pipe, which is sequentially fitted with an inner insulation layer, a composite protective layer, and a corrosion-resistant and seepage-proof layer from the inside out. The shearing assembly is connected to the pipe body via a fixed bearing, which is mounted on a shearing box. The shearing box has a cylindrical structure and contains a blade ring and a pressure cylinder. The blade ring is rotatably connected to the shearing box. An air bladder is provided inside the fixed bearing, and multiple sets of functional blades are installed on the blade ring. This cutting device cannot cut the L-shaped and T-shaped joints of the pipeline insulation material. Therefore, there is a need to provide a pipeline insulation material cutting mold that can solve the problem of poor cutting accuracy at the L-shaped and T-shaped joints of the pipeline insulation material in the prior art. Summary of the Invention

[0004] The purpose of this utility model is to provide a pipe insulation material cutting mold that can solve the problem of poor cutting accuracy of pipe insulation material at the L-shaped and T-shaped joint positions of pipes in the prior art.

[0005] This utility model is implemented as follows:

[0006] A pipe insulation material cutting mold includes a mold body, which is a hollow cylindrical structure and fits onto the outside of the pipe insulation material. One end of the mold body forms a first cutting surface. When cutting the pipe insulation material along the first cutting surface, the end of the pipe insulation material forms a corner surface consistent with the first cutting surface. Two sections of pipe insulation material are joined together through the corner surface to form pipe insulation material at an L-shaped joint position. A second cutting surface is formed in the middle of the mold body. When cutting the pipe insulation material along the second cutting surface, a first connecting surface consistent with the second cutting surface is formed on the pipe insulation material. The other end of the mold body forms a third cutting surface. When cutting the pipe insulation material along the third cutting surface, the end of the pipe insulation material forms a second connecting surface consistent with the third cutting surface. The first connecting surface and the second connecting surface match, allowing two sections of pipe insulation material to be joined together to form pipe insulation material at a T-shaped joint position.

[0007] The first cutting surface is a sloping structure with an inclination angle of 45°. The height of the first cutting surface is consistent with the height of the mold body, so that the corner surface of the pipe insulation material has a 45° sloping structure.

[0008] The second cutting surface has an inwardly concave V-shaped structure, which forms a V-shaped notch on the first connecting surface of one section of pipe insulation material. The third cutting surface has an outwardly convex V-shaped structure, which forms a V-shaped protrusion on the second connecting surface of another section of pipe insulation material. The inwardly concave V-shaped structure matches the outwardly convex V-shaped structure.

[0009] The concave V-shaped structure and the convex V-shaped structure have an angle of 90°, and the concave V-shaped structure and the convex V-shaped structure are axisymmetric structures.

[0010] The opening of the concave V-shaped structure is located at the top of the mold body, and the depth of the concave V-shaped structure is half the height of the mold body. The opening width of the concave V-shaped structure is the same as the height of the mold body.

[0011] The opening of the convex V-shaped structure faces the first cutting surface, and the height of the convex V-shaped structure is the same as the height of the mold body, while the depth of the convex V-shaped structure is half the height of the mold body.

[0012] The mold body, the first cutting surface, the second cutting surface, and the third cutting surface are integrally formed.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] 1. This utility model features a mold body with a first cutting surface, a second cutting surface, and a third cutting surface. The mold body is selected and integrally molded according to the size of the pipe insulation material to be cut. When in use, the mold body is simply fitted onto the pipe insulation material, and the first, second, and third cutting surfaces ensure the standardization and consistency of the joint shape after cutting. This solves the problem of poor cutting accuracy of the joint shape of pipe insulation materials in the prior art, and can ensure that the joint of the pipe insulation material at the L / T joint of the pipe is tight and flat, and the adhesion is firm and reliable. It reduces the construction difficulty while ensuring the insulation performance.

[0015] 2. Because this utility model has a first cutting surface, which is a 45° bevel, the two sections of pipe insulation material after cutting can be vertically joined together at the corner to form an L-shaped structure. The two corner surfaces fit together smoothly and tightly, which is suitable for insulation construction at the L-shaped joint of the pipe, and helps to improve construction efficiency and construction quality.

[0016] 3. This utility model has a second cutting surface and a third cutting surface. The second cutting surface is a right-angled concave V-shaped structure, and the third cutting surface is a right-angled convex V-shaped structure. This allows the two sections of pipe insulation material after cutting to be perpendicularly joined together to form a T-shaped structure through the first connecting surface and the second connecting surface. The first connecting surface and the second connecting surface fit together smoothly and tightly, which is suitable for insulation construction at the T-shaped joint of the pipe, and helps to improve construction efficiency and construction quality.

[0017] 4. This utility model has a simple structure, is easy to use, has good versatility and reusability, can adapt to different construction conditions, is easy to obtain materials and manufacture, has low cost, and comprehensively improves the construction efficiency, economy and standardization of pipeline projects.

[0022] In the figure, 1 is the mold body, 11 is the first cutting surface, 12 is the second cutting surface, and 13 is the third cutting surface. Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Please see the appendix Figure 1 To be continued Figure 4 A pipe insulation material cutting mold includes a mold body 1, which has a hollow cylindrical structure and is fitted onto the outside of the pipe insulation material. One end of the mold body 1 forms a first cutting surface 11. When cutting the pipe insulation material along the first cutting surface 11, the end of the pipe insulation material forms a corner surface consistent with the first cutting surface 11. Two sections of pipe insulation material are joined together through the corner surface to form pipe insulation material at an L-shaped joint position. A second cutting surface 12 is formed in the middle of the mold body 1. When cutting the pipe insulation material along the second cutting surface 12, a first connecting surface consistent with the second cutting surface 12 is formed on the pipe insulation material. The other end of the mold body 1 has a third cutting surface 13. When cutting the pipe insulation material along the third cutting surface 13, the end of the pipe insulation material forms a second connecting surface consistent with the third cutting surface 13. The first connecting surface and the second connecting surface match, so that two sections of pipe insulation material are joined together to form pipe insulation material at a T-shaped joint position.

[0025] By setting the first cutting surface 11, when cutting the pipe insulation material, the end of the pipe insulation material can form a corner surface with the same shape as the first cutting surface 11. Thus, when the two pipe insulation materials are perpendicularly joined through the corner surface, the two corner surfaces at the joint position are tightly and flatly fitted due to the consistent shape of the corner surfaces. This ensures the bonding reliability of the two pipe insulation materials, reduces the construction difficulty, and thus ensures the insulation performance at the L-shaped joint of the pipe.

[0026] By setting the second cutting surface 12 and the third cutting surface 13, when cutting the pipe insulation material, a first connecting surface with the shape of the second cutting surface 12 can be formed on one section of the pipe insulation material, and a second connecting surface with the shape of the third cutting surface 13 can be formed at the end of the other section of the pipe insulation material. Thus, when the two sections of pipe insulation material are perpendicularly joined through the first connecting surface and the second connecting surface, the first connecting surface and the second connecting surface match, ensuring that the first connecting surface and the second connecting surface at the joining position are tightly and flatly bonded. This ensures the bonding reliability of the two sections of pipe insulation material, reduces construction difficulty, and thus ensures the insulation performance at the T-joint position of the pipe.

[0027] The first cutting surface 11, the second cutting surface 12, and the third cutting surface 13 can be used with different cutting equipment to cut along the first cutting surface 11, the second cutting surface 12, and the third cutting surface 13, ensuring that the cutting is neat, fast, and standardized, avoiding cutting accuracy errors in the joint position shape, and is suitable for cutting tubular thermal insulation materials made of materials such as rock wool, glass wool, aluminum silicate fiber, polyurethane foam, and polystyrene foam.

[0028] Please see the appendix Figure 1 and attached Figure 2 The first cutting surface 11 is a sloping structure with an inclination angle of 45°. The height of the first cutting surface 11 is consistent with the height of the mold body 1, so that the corner surface of the pipe insulation material is a 45° sloping structure.

[0029] The first cutting surface 11 is designed at 45°. After cutting, the corner surfaces of the two pipe insulation materials are both 45° inclined structures, which facilitates the vertical connection of the two pipe insulation materials at the L-shaped pipe joint. The construction is simple and convenient, and can meet the insulation construction requirements at the L-shaped pipe joint.

[0030] Please see the appendix Figure 1 and attached Figure 2 The second cutting surface 12 has an inwardly concave V-shaped structure, which forms a V-shaped notch on the first connecting surface of one section of pipe insulation material. The third cutting surface 13 has an outwardly convex V-shaped structure, which forms a V-shaped protrusion on the second connecting surface of another section of pipe insulation material. The shape and size of the inwardly concave V-shaped structure and the outwardly convex V-shaped structure are matched.

[0031] By setting the second cutting surface 12 and the third cutting surface 13 of the concave and convex V-shaped structures, V-shaped notches and V-shaped protrusions are formed on the two sections of pipe insulation material, which facilitates the vertical connection of the two sections of pipe insulation material at the pipe T-joint position. The construction is simple and convenient and can meet the insulation construction requirements at the pipe T-joint position.

[0032] Please see the appendix Figure 1 and attached Figure 2 The angle between the concave V-shaped structure and the convex V-shaped structure is 90°, and the concave V-shaped structure and the convex V-shaped structure are axisymmetric structures.

[0033] The angles of the concave V-shaped structure and the convex V-shaped structure can be adjusted adaptively according to the actual docking requirements. It is only necessary to make the angles of the concave V-shaped structure and the convex V-shaped structure consistent; preferably 90°.

[0034] Please see the appendix Figure 1 and attached Figure 2 The opening of the concave V-shaped structure is located at the top of the mold body 1, and the depth of the concave V-shaped structure is half the height of the mold body 1. The opening width of the concave V-shaped structure is consistent with the height of the mold body 1.

[0035] Preferably, the size of the mold body 1 can be selected according to the size adaptability of the pipe insulation material. The inner diameter of the mold body 1 is slightly larger than the outer diameter of the pipe insulation material, so that the mold body 1 can be fitted onto the pipe insulation material and can slide on the pipe insulation material.

[0036] The depth of the concave V-shaped structure can be adjusted adaptively according to actual docking requirements. If the depth of the concave V-shaped structure is too small, the contact area between the first and second connecting surfaces will be small, which may affect the connection strength. If the depth of the concave V-shaped structure is too large, the cutting depth of the pipe insulation material at the connection position will be too deep, which may easily affect the structural strength of the pipe insulation material. Therefore, it is advisable to set the depth of the concave V-shaped structure to half the height of the mold body 1.

[0037] Please see the appendix Figure 1 and attached Figure 2 The opening of the convex V-shaped structure faces the first cutting surface 11, and the height of the convex V-shaped structure is the same as the height of the mold body 1, and the depth of the convex V-shaped structure is half the height of the mold body 1.

[0038] The opening width of the concave V-shaped structure arranged radially along the mold body 1 is consistent with the height of the mold body 1, and the height of the convex V-shaped structure arranged axially along the mold body 1 is consistent with the height of the mold body 1, so that the convex V-shaped structure and the concave V-shaped structure are matched and set to ensure seamless fit between the first connecting surface and the second connecting surface after cutting.

[0039] Please see the appendix Figure 1 To be continued Figure 4 The mold body 1, the first cutting surface 11, the second cutting surface 12 and the third cutting surface 13 are integrally formed.

[0040] Preferably, the pipe insulation material cutting mold of this utility model can be made by printing ABS plastic, or by cutting PVC pipe, metal pipe or other pipe materials to form an integrated structure with high structural strength, not easy to deform or be damaged, and easy to reuse.

[0041] Please see the appendix Figure 1 To be continued Figure 4 When cutting pipe insulation material, the mold body 1 is placed on the pipe insulation material and moved to the position where it needs to be cut.

[0042] When cutting the L-shaped joint, align the first cutting surface 11 with the cutting position of the pipe insulation material. Use the cutting equipment to cut the pipe insulation material along the first cutting surface 11, so that the end of the pipe insulation material forms a 45° beveled corner surface. Both sections of pipe insulation material are cut in the same way, which will not be described in detail here.

[0043] By joining two sections of pipe insulation material at their corners, they can be perpendicularly joined to form an L-shaped structure. This structure can then be used for insulation at the L-shaped joint of the pipe. The cut surface is flat, and the shape matches and fits well, ensuring a firm bond between the two sections of insulation material and thus guaranteeing the insulation performance at the L-shaped joint.

[0044] When cutting at the T-joint position, align the second cutting surface 12 with the cutting position of one section of pipe insulation material, and use the cutting equipment to cut the pipe insulation material along the second cutting surface 12, forming a concave V-shaped notch on the pipe insulation material. Align the third cutting surface 13 with the cutting position of another section of pipe insulation material, and use the cutting equipment to cut the pipe insulation material along the third cutting surface 13, forming a convex V-shaped structure at the end of the pipe insulation material.

[0045] The convex V-shaped structure is matched and inserted into the concave V-shaped notch, so that the two sections of pipe insulation material can be perpendicularly joined to form a T-shaped structure. This structure can then be used for insulation construction at the T-joint of the pipe. The cut surface is flat, and the shape matching and fit are good, ensuring that the two sections of pipe insulation material are firmly bonded, thereby ensuring the insulation performance at the T-joint.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
