Description
Technical Field
[0001] This utility model relates to the field of direct-buried insulated pipe production technology, specifically a cutting device for producing steel-clad prefabricated direct-buried insulated pipes. Background Technology
[0002] As a core component of centralized heating, cooling and industrial pipeline transportation systems, steel-jacketed prefabricated direct-buried insulated pipes have been widely used in urban infrastructure construction, energy transmission and other fields due to their excellent thermal insulation performance, corrosion resistance and structural stability. These pipes are usually composed of multiple layers such as working steel pipe, insulation layer, outer protective steel pipe and anti-corrosion layer. Their production process requires multiple processes such as raw material processing, composite molding and length cutting. Among them, the cutting process directly affects the installation accuracy and connection sealing of the pipe, and plays a key role in the quality of subsequent projects. However, existing cutting devices used in the production of steel-clad prefabricated direct-buried insulated pipes still have some problems in use: First, the existing cutting device lacks a structure to stably fix the insulation pipe, which can easily cause the insulation pipe to move and shift during the cutting process, thus affecting the cutting effect of the insulation pipe. Secondly, the cutting blades in existing cutting devices are generally installed in a fixed manner. After prolonged use, the cutting blades are prone to wear and tear, so they need to be replaced. However, the fixed installation method makes the replacement process cumbersome and not conducive to quick operation, thus reducing the overall ease of use of the cutting device. Utility Model Content
[0003] To address the existing problems of easy movement of the insulation pipe during cutting and inconvenient replacement of the cutting blade, the purpose of this utility model is to provide a cutting device for the production of steel-clad prefabricated direct-buried insulation pipes.
[0004] To solve the above technical problems, the present invention adopts the following technical solution: a cutting device for producing steel-clad prefabricated direct-buried insulated pipes, comprising a workbench, a bracket fixedly connected to the upper surface of the workbench, a protective cover fixedly connected to the upper surface of the bracket, a cylinder fixedly installed on the inner wall of the protective cover, a connecting plate fixedly connected to the output end of the cylinder, a vertical rod fixedly connected to the lower surface of the connecting plate, and a servo motor fixedly installed on one side of the vertical rod, the output end of the servo motor passing through one side of the vertical rod and having a connecting component, a cutting blade body movably installed on one side of the connecting component, placement seats symmetrically fixedly installed on the upper surface of the workbench, and a ring-shaped clamping mechanism jointly provided on the upper and lower surfaces of the workbench.

A slider is threaded on the outer surface of the bidirectional screw, and a moving rod is fixedly connected to both sides of the slider. Limiting grooves for cooperating with the moving rods are symmetrically opened on both sides of the housing. The moving rod passes through the limiting grooves, and the top end of the moving rod passes through the worktable and is fixedly connected to a clamping plate.
[0006] Preferably, the connecting assembly includes a mounting shell, which is rotatably disposed on one side of the vertical rod.

[0015] 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.
[0016] Example: Figure 1-5 As shown, this utility model provides a cutting device for the production of steel-clad prefabricated direct-buried insulated pipes, including a workbench 1. A bracket 5 is fixedly connected to the upper surface of the workbench 1, and a protective cover 4 is fixedly connected to the upper surface of the bracket 5. A cylinder 14 is fixedly installed on the inner wall of the protective cover 4. The protective cover 4 serves to protect the cylinder 14. A connecting plate 13 is fixedly connected to the output end of the cylinder 14. The connecting plate 13 transmits the power of the cylinder 14 to the vertical rod 7, ensuring the stability of the power transmission and making the lifting and lowering action of the cutting blade body 6 more stable.
[0017] A vertical rod 7 is fixedly connected to the lower surface of the connecting plate 13, and a servo motor 8 is fixedly installed on one side of the vertical rod 7. The vertical rod 7 provides a mounting carrier for components such as the servo motor 8 and the base 10, while ensuring that the positions of the servo motor 8 and the cutting blade body 6 correspond to each other, ensuring effective transmission of cutting power. The base 10 is fixedly connected to one side of the vertical rod 7, and the servo motor 8 is fixedly installed on the upper surface of the base 10. The base 10 plays an auxiliary role in fixing the servo motor 8, reducing the vibration of the servo motor 8 during operation, and ensuring that the power at its output end is stably transmitted to the connecting component 3. The output end of the servo motor 8 passes through one side of the vertical rod 7 and is provided with the connecting component 3. The connecting component 3 enables quick disassembly of the cutting blade body 6. The cutting blade body 6 is movably mounted on one side of the connecting component 3. The cutting blade body 6, as the direct cutting component, cuts the insulation pipe through high-speed rotation and is the core actuator for completing the cutting operation.
[0018] A vertical rod 12 is fixedly connected to the lower surface of the support 5, and a baffle 11 is fixedly connected to the lower surface of the vertical rod 12. The vertical rod 12 connects the support 5 and the baffle 11, providing stable support for the baffle 11 and ensuring that the baffle 11 can effectively block debris. The baffle 11 is positioned above the cutting blade body 6, which can further prevent cutting debris from splashing upwards and enhance the protective effect. A placement seat 9 is symmetrically fixedly installed on the upper surface of the workbench 1. The placement seat 9 provides a support platform for the insulation pipe, so that the insulation pipe is placed horizontally before cutting. The upper and lower surfaces of the workbench 1 are jointly provided with a ring-shaped clamping mechanism 2. The ring-shaped clamping mechanism 2 can fix the insulation pipe and prevent the insulation pipe from moving or shifting during the cutting process, thus ensuring cutting accuracy.
[0019] The ring-shaped clamping mechanism 2 includes a housing 26, which is fixedly installed on the lower surface of the workbench 1. A DC motor 201 is fixedly connected to one side of the housing 26, and a support plate 29 is fixedly installed on one side of the housing 26. The DC motor 201 is fixedly installed on the upper surface of the support plate 29. The support plate 29 provides a stable mounting position for the DC motor 201. The DC motor 201 provides power to the ring-shaped clamping mechanism 2. The output end of the DC motor 201 passes through one side of the housing 26 and is fixedly connected to a bidirectional screw 25. The DC motor 201 drives the bidirectional screw 25 to rotate through the rotation of its output end.
[0020] The outer surface of the bidirectional screw 25 is threaded with a slider 28. The slider 28 slides along the housing 26 under the drive of the bidirectional screw 25, converting rotational motion into linear motion. One end of the bidirectional screw 25 is damped and rotatably connected to the inner wall of the housing 26. The damped rotatable connection allows the bidirectional screw 25 to maintain its current position after it stops rotating, preventing the slider 28 from shifting due to external forces and ensuring the clamping stability of the clamping plate 23. The slider 28 is slidably connected to the housing 26. The slider 28 is threaded on the opposite thread direction of the outer surface of the bidirectional screw 25, and both sides of the slider 28 are fixedly connected with moving rods 24. The opposite thread direction allows the two sliders 28 to move closer or further away synchronously. The moving rods 24 drive the clamping plate 23 to achieve a ring-shaped clamping or releasing of the insulation tube.
[0021] The housing 26 has symmetrically provided limiting grooves 27 on both sides for use with the moving rod 24. The moving rod 24 passes through the limiting grooves 27, which restrict the range of movement of the moving rod 24, preventing it from detaching from the housing 26 due to excessive movement, while ensuring the accuracy of the movement direction. The upper surface of the worktable 1 has a rectangular array of through grooves 21 for use with the moving rod 24. The corresponding moving rod 24 is slidably connected to the corresponding through groove 21. The through groove 21 provides a channel for the moving rod 24 to pass through the worktable 1, allowing the moving rod 24 to... The power inside the housing 26 can be transmitted to the clamping plate 23 above the workbench 1. The top of the moving rod 24 passes through the workbench 1 and is fixedly connected to the clamping plate 23. Under the drive of the moving rod 24, the clamping plate 23 realizes the ring-shaped clamping of the insulation pipe. Through close contact with the surface of the insulation pipe, the pipe is prevented from moving during cutting. The inner wall of the clamping plate 23 is fixedly connected to the anti-slip pad 22. The anti-slip pad 22 increases the friction between the clamping plate 23 and the surface of the insulation pipe, further improving the clamping stability, while avoiding direct contact between the clamping plate 23 and the pipe, which would cause surface scratches.
[0022] The connecting assembly 3 includes a mounting shell 31, which is rotatably mounted on one side of the vertical rod 7. The output end of the servo motor 8 passes through one side of the vertical rod 7 and is fixedly connected to one side of the mounting shell 31. The mounting shell 31 serves as the mounting carrier for the cutting blade body 6. Its rotatable arrangement ensures that the cutting blade body 6 can rotate synchronously with the output end of the servo motor 8 to achieve the cutting action. The inner wall of the mounting shell 31 is provided with a magnetic suction groove 32. A magnetic suction rod 34 is magnetically inserted into the inner wall of the magnetic suction groove 32. The cutting blade body 6 is fixedly mounted on the end of the magnetic suction rod 34. The magnetic attraction between the magnetic suction rod 34 and the magnetic suction groove 32 achieves quick pre-fixation of the cutting blade body 6, simplifies the installation steps, and lays the foundation for quick replacement of the cutting blade body 6 in the future.
[0023] The magnetic groove 32 and the magnetic rod 34 are magnetically connected by a bolt 33. The bolt 33 quickly positions and connects the magnetic groove 32 and the magnetic rod 34 through magnetic attraction. While ensuring the connection is firm, it is easier to disassemble than the traditional fixing method, which significantly improves the replacement efficiency of the cutting blade body 6 and enhances the ease of use of the device.
[0024] Working principle: First, the steel-clad prefabricated direct-buried insulated pipe to be cut is placed on the placement seats 9 symmetrically installed on the upper surface of the workbench 1. The placement seats 9 provide stable support for the insulated pipe, keeping it in a horizontal state, which facilitates subsequent clamping operations.
[0025] Then, the ring-type clamping mechanism 2 is activated to fix the insulation pipe. The DC motor 201 on the support plate 29 is activated. The output end of the DC motor 201 drives the bidirectional screw 25 to rotate in a damped manner on the inner wall of the housing 26. The rotation of the bidirectional screw 25 will drive the two sliders 28 to move synchronously in opposite directions along the housing 26.
[0026] The moving rods 24 on both sides of the slider 28 slide in the limiting groove 27 of the housing 26 and the through groove 21 of the worktable 1, causing the clamping plate 23 connected at the top to move closer to each other until the anti-slip pad 22 on the inner wall of the clamping plate 23 is in close contact with the outer surface of the insulation pipe, thereby achieving a ring-shaped fixation of the insulation pipe and effectively preventing the insulation pipe from moving or shifting during the cutting process.
[0027] After the insulation pipe is fixed, the position where it needs to be cut is directly below the cutting blade body 6.
[0028] Then, the cutting mechanism starts working. The cylinder 14 installed on the inner wall of the protective cover 4 is activated, and its output end pushes the connecting plate 13 to move downward. The connecting plate 13 drives the vertical rod 7 and the servo motor 8 on the base 10 on one side of the vertical rod 7 to move downward synchronously, so that the cutting blade body 6 on one side of the connecting component 3 approaches the position of the heat preservation pipe to be cut.
[0029] At the same time, the servo motor 8 starts, and its output end drives the mounting shell 31 to rotate. The mounting shell 31 drives the cutting blade body 6 to rotate at high speed through the magnetic attraction between the magnetic groove 32 and the magnetic rod 34 and the fixing of the bolt 33.
[0030] Under the continuous push of cylinder 14, the rotating cutting blade body 6 gradually cuts into the insulation pipe, completing the cutting operation.
[0031] During the cutting process, the baffle 11 connected to the upright 12 on the lower surface of the bracket 5 is located above the cutting blade body 6, which can block the flying of cutting debris, and further improve the safety of operation in conjunction with the protective cover 4.
[0032] When the cutter body 6 needs to be replaced due to wear and tear from prolonged use, simply unscrew the bolt 33 between the magnetic groove 32 and the magnetic rod 34, and take advantage of the separability of the magnetic connection to remove the magnetic rod 34 from the magnetic groove 32 of the mounting shell 31, thus removing the old cutter body 6.
[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
