Description

Technical Field

[0001] This utility model relates to the field of pipeline and valve processing technology, specifically a cutting device for valve and pipeline processing. Background Technology

[0002] Valves are control components in pipeline fluid transport systems. They are used to change the cross-sectional area of ​​the passage and the direction of medium flow, and have functions such as guiding, stopping, throttling, checking back, diverting or overflowing pressure relief. Valves are mostly made of materials such as cast iron, cast steel, and stainless steel. Valves are generally connected to pipelines to transport media. When processing valve pipelines, valve pipeline cutting devices are needed to cut the valve pipelines.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219484376U) discloses a cutting device for processing pipe valves, comprising a base, two electric push rods symmetrically fixedly connected to the top of the base, and sliding rods fixedly connected to the four corners of the base. A top plate is fixedly installed at the output end of the electric push rods, and the top plate is slidably mounted on the sliding rods. A positioning and cutting mechanism is provided at the center of the bottom wall of the top plate, and a uniform force-bearing mechanism is provided at the center of the top of the base, located directly below the positioning and cutting mechanism.

[0004] In the aforementioned patent, a positioning and cutting mechanism with uniform force distribution is used to stably clamp and cut the valve in the pipeline. Simultaneously, symmetrically arranged fixed bases and limiting blocks are used to stably clamp both sides of the pipeline cutting area, ensuring uniform force distribution on both sides of the pipeline end face cutting area. This reduces the problem of tilting of the cutting end face due to unilateral clamping and effectively improves cutting quality. However, while the positioning and cutting mechanism can effectively clamp and fix larger pipeline valves, it is difficult to achieve stable clamping and fixing for smaller pipeline valves. During the cutting of smaller pipeline valves, the valve may shake or shift, which may cause the cutting tool to fail to strictly follow the predetermined trajectory, resulting in deviations in the cutting position.

[0005] Therefore, this utility model provides a cutting device for valve and pipeline processing to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This utility model provides a cutting device for valve and pipeline processing, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a cutting device for processing valves and pipes, the cutting device for processing valves and pipes includes a base plate, a cutting blade disposed above the base plate, a movable plate slidably mounted on the base plate, a connecting frame fixedly mounted on the movable plate, a clamping ring fixedly mounted on the connecting frame, and a clamping mechanism disposed inside the clamping ring for clamping valves and pipes of different sizes.

[0008] The clamping mechanism includes a threaded disc rotatably mounted inside the clamping ring, a gear ring fixedly mounted on one side of the threaded disc, a servo motor fixedly mounted inside the clamping ring, a gear fixedly mounted on the output end of the servo motor, a moving block screwed onto the threaded disc, and a limiting plate fixedly mounted on both ends of the moving block.

[0009] As a preferred technical solution of this application, the gear meshes with the gear ring, and multiple moving blocks are provided. The moving blocks are arranged in a ring array inside the clamping ring, and the moving blocks pass through the clamping ring.

[0010] As a preferred technical solution of this application, a plurality of support columns are fixedly connected to the top of the base plate, and a top plate is fixedly connected to the top of the support columns.

[0011] As a preferred technical solution of this application, an electric push rod is fixedly connected to the top of the top plate, the movable end of the electric push rod passes through the top plate, and is fixedly connected to the cutting blade through a protective cover.

[0012] As a preferred technical solution of this application, the base plate has a groove inside, the movable plate is slidably installed inside the groove, and a bidirectional lead screw is movably connected inside the groove, the bidirectional lead screw passing through the movable plate.

[0013] As a preferred technical solution of this application, the movable plate has a threaded hole inside that is adapted to the bidirectional lead screw, one end of the bidirectional lead screw passes through the slide groove, and a handwheel is fixedly connected to one end of the bidirectional lead screw.

[0014] (III) Beneficial Effects This utility model has a simple structure and is easy to use. Through the clamping mechanism, the servo motor is started, driving the gear to rotate, which in turn drives the threaded disc to rotate inside the clamping ring. Since the moving block is screwed onto the threaded disc, when the threaded disc rotates, the moving block will move along its axial direction and move towards the center. Through the action of the limiting plate, the valve pipe is clamped. If the valve pipe is large, the servo motor rotates in the opposite direction, causing multiple moving blocks to expand outward, ensuring that the limiting plate is tightly fitted with the inner wall of the clamped valve, thus achieving internal support clamping. This effectively reduces the shaking or displacement of the pipe valve during operation, improving the cutting accuracy and quality. Attached Figure Description

[0017] 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.

[0018] This utility model provides a cutting device for valve and pipe processing, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the valve and pipeline processing cutting device includes a base plate 1, a cutting blade 2 disposed above the base plate 1, a movable plate 3 slidably mounted on the base plate 1, a connecting frame 4 fixedly mounted on the movable plate 3, a clamping ring 5 fixedly mounted on the connecting frame 4, and a clamping mechanism disposed inside the clamping ring 5 for clamping valves and pipelines of different sizes.

[0019] The clamping mechanism includes a threaded disc 6 rotatably mounted inside the clamping ring 5, a toothed ring 7 fixedly mounted on one side of the threaded disc 6, a servo motor 8 fixedly mounted inside the clamping ring 5, a gear 9 fixedly mounted on the output end of the servo motor 8, a moving block 10 screwed onto the threaded disc 6, and a limiting plate 11 fixedly mounted on both ends of the moving block 10.

[0020] Gear 9 meshes with gear ring 7. Multiple moving blocks 10 are provided. The moving blocks 10 are arranged in a ring array inside the clamping ring 5 and pass through the clamping ring 5.

[0021] When using this valve and pipe processing cutting device, first place the base plate 1 in a suitable position, then place the valve or pipe to be cut inside the clamping ring 5. Start the servo motor 8, which drives the gear 9 to rotate. The gear 9 meshes with the gear ring 7, thereby causing the threaded disc 6 to rotate inside the clamping ring 5. Since the moving block 10 is screwed onto the threaded disc 6, when the threaded disc 6 rotates, the moving block 10 will move along the axial direction of the threaded disc 6 under the action of the thread. There are multiple moving blocks 10, which are arranged in a ring array inside the clamping ring 5. The distribution of the moving blocks 10 allows multiple moving blocks 10 to move towards the center simultaneously, thereby clamping the valve pipe through the limiting plate 11. If the valve pipe is large, the servo motor 8 rotates in the opposite direction, ultimately causing the multiple moving blocks 10 to move outward, so that the limiting plate 11 fits against the inner wall of the clamped valve, completing the internal support clamping of the clamped valve. After clamping the valve pipe, the cutting blade 2 can be activated to cut the valve pipe. Due to the design of the clamping mechanism, valve pipes of different sizes can be clamped, thereby improving the applicability and cutting accuracy of the cutting device.

[0022] Furthermore, in order to control the cutting blade 2 to cut the valve pipe, such as... Figure 1 , Figure 2 and Figure 3 As shown, a plurality of support columns 12 are fixedly connected to the top of the base plate 1, and a top plate 13 is fixedly connected to the top of the support columns 12.

[0023] An electric push rod 14 is fixedly connected to the top of the top plate 13. The movable end of the electric push rod 14 passes through the top plate 13 and is fixedly connected to the cutting blade 2 through a protective cover.

[0024] When in use, the electric push rod 14 extends and retracts, driving the cutting blade 2 to move up and down, thereby cutting the valve pipe. During the cutting process, the clamping mechanism firmly clamps the valve pipe, ensuring the accuracy and stability of the cutting. In addition, the extension and retraction distance of the electric push rod 14 can be precisely adjusted by the control device, thus meeting the cutting needs of valve pipes of different thicknesses. This design not only improves the cutting efficiency but also greatly enhances the functionality and practicality of the cutting device.

[0025] It should be noted that, in order to clamp valves and pipes of different lengths, such as... Figure 1 , Figure 2 and Figure 3 As shown, a groove 15 is provided inside the base plate 1, and the movable plate 3 is slidably installed inside the groove 15. A two-way lead screw 16 is movably connected inside the groove 15, and the two-way lead screw 16 passes through the movable plate 3.

[0026] The movable plate 3 has a threaded hole that matches the bidirectional lead screw 16. One end of the bidirectional lead screw 16 passes through the slide groove 15, and a handwheel 17 is fixedly connected to one end of the bidirectional lead screw 16.

[0027] When in use, the valve and pipe processing cutting device can drive the bidirectional lead screw 16 to rotate by turning the handwheel 17. Since the moving plate 3 has a threaded hole that matches the bidirectional lead screw 16, and the bidirectional lead screw 16 passes through the moving plate 3, the bidirectional lead screw 16 can drive the two moving plates 3 to move in opposite or opposite directions along the slide groove 15 during rotation, thereby clamping valves and pipes of different lengths and improving the applicability and flexibility of the cutting device.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
