Description

Technical Field

[0001] The invention relates to the technical field of pump body cutting, in particular to high-precision cutting equipment for a metal pump body of a twin-screw pump and a use method thereof. Background Art

[0002] Pumps and valves are collectively referred to as pumps and valves. They are widely used in liquid and gas delivery systems. Pumps and valves are usually used to control the flow, pressure and direction of fluids. Pumps are mainly used to provide power for fluid flow. When pumps and valves need to be modified to adapt to new process requirements or improve performance, it is necessary to cut the pipes on both sides of the pump body to change its internal structure or install new components.

[0003] There are many existing technologies for high-precision cutting equipment for metal pump bodies of twin-screw pumps and methods of using the same, such as: Chinese patent publication number CN119016795A discloses a pump valve housing cutting device, including a U-shaped base, side frames are fixedly arranged at both ends of the upper surface of the U-shaped base, cross-links are arranged on both sides of the two side frames close to each other, and a vertical plate is arranged at the end of the cross-link away from the side frame, and lifting components are arranged on both vertical plates. A support frame is fixedly arranged on one side of the upper surface of the U-shaped base, and a lifting top seat is fixedly arranged on the upper surface of the support frame. The upper wall of the lifting top seat is provided with a strip groove, and the lifting top seat is provided with a cutting component through the strip groove. The pump valve housing cutting device is provided with a lifting component. When the two brackets are close to each other and inserted under the pump valve, the lifting cylinder works, the piston rod shrinks into the lifting cylinder, and the lower end of the piston rod pulls the clamping plate and the bracket upward through the limit slider, so that the bracket can effectively drive the pump valve to move upward synchronously, so as to facilitate the cutting knife to complete the cutting, and does not need to be manually carried to the workbench, saving time and labor.

[0004] However, in actual use, there are still some problems that need to be solved: 1. Some cutting work relies on manual operation. Operators need to hold cutting tools for a long time to accurately cut the pipes on both sides of the pump body. Since the pump shell material is usually relatively hard, the cutting process requires a lot of physical strength and the labor intensity is extremely high. Long-term high-intensity work can easily make operators feel tired, which in turn reduces cutting accuracy and increases scrap rate; 2. During the actual pump casing cutting operation, the existing cutting equipment often lacks effective fixing measures for the connecting pipes on both sides of the pump body, which makes the pipes suspended in the cutting process and easily fall due to external forces such as vibration and collision. Once the pipe falls, it may not only directly injure the on-site operators and cause serious safety accidents, but also cause damage to surrounding equipment and facilities, resulting in production interruption and huge economic losses.

[0005] Therefore, a high-precision cutting device for the metal pump body of a twin-screw pump and its usage method are proposed. Summary of the Invention

[0016] The second object of the present invention is to provide a method for using a high-precision cutting device for a double-screw pump metal pump body. Based on the above high-precision cutting device for a double-screw pump metal pump body, it includes the following steps: S1. When the pump is placed inside the placement frame, by rotating the threaded rods on both sides of the placement frame, the pressing plate is driven to move in the vertical direction, and by adjusting the pressing heights of the pressing plates on both sides, the top of the pump body is pressed and fixed. S2. By controlling the moving seat to move on the electric guide rail, the moving seat drives the bottom plate to move in the horizontal direction. When the balance plate provided above the bottom plate moves to below the cutting center position, by controlling the electric telescopic rod to drive the support seat to move in the vertical direction, the support plates provided on both sides of the balance plate are made to fit the bottom of the pump body pipes.

By controlling the piston rod at the end of the second cylinder to drive the push plate to move in the axial direction, the rack is driven to move during the movement of the push plate. When the rack moves to under the gear, the movement of the rack drives the gear to mesh and rotate, so that the baffle rotates to the vertical position to block the end face of the cutting position. S4. Control the piston rod at the end of the first cylinder to drive the moving frame to move in the vertical direction, and the cutting machine is driven by the moving frame to cut the pump body pipes during the movement of the moving frame.

[0017] Compared with the prior art, the beneficial effects of the present invention: 1. The high-precision cutting equipment for the metal pump body of the twin-screw pump and its usage method. Control the movement of the moving seat on the surface of the electric guide rail. The moving seat drives the bottom plate to move horizontally. When the balance plate arranged above the bottom plate moves to below the cutting center position, control the electric telescopic rod to drive the support seat to move vertically, so that the support plates arranged on both sides of the balance plate are attached to the bottom of the pump body pipeline. When cutting the pump body, since the distance between the pressure plates arranged on both sides of the cutting machine is the same as the distance between the support plates, when the cutting machine drives the pressure plates to move downward for cutting, the pressure plates are in extrusion cooperation with the support plates. When the cutting material of the pump body is separated, it is subjected to the clamping force between the pressure plates and the support plates, so as to ensure that the cutting material is fixed at the cutting position, thereby avoiding the direct dropping of the cutting material and improving the safety of the cutting operation.

[0018] 2. The high-precision cutting equipment for the metal pump body of the twin-screw pump and its usage method. Control the piston rod at the end of the second cylinder to drive the push plate to move along the axial direction. During the movement of the push plate, the rack is driven to move.

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1-8As shown, a high-precision cutting device for the metal pump body of a twin-screw pump and its usage method are provided, including a workbench 100. A guide rail frame 101 is provided on the surface of the workbench 100. A sliding frame 102 is provided on the surface of the guide rail frame 101. The sliding frames 102 are arranged symmetrically. Rotating motors 103 are provided at the ends of the sliding frames 102. The rotating motors 103 penetrate through the sliding frames 102 and friction wheels 104 are provided at the ends. The friction wheels 104 move on the surface of the guide rail frame 101. Auxiliary wheels 105 are provided on the inner walls of the sliding frames 102. Extension plates 106 are provided at the ends of the sliding frames 102. A storage frame 200 is provided below the guide rail frame 101. A clamping assembly is provided on one side of the storage frame 200. A cutting assembly 300 is provided on the surface of the extension plate 106. Support assemblies 400 are provided on both sides of the storage frame 200. The support assemblies 400 are used to support the bottoms of the pipes on both sides of the pump body and cooperate with the cutting assembly 300 to fix the cutting end. The support assemblies 400 include electric guide rails 401 provided on both sides of the storage frame 200. Moving seats 402 are slidably provided on the surfaces of the electric guide rails 401. Bottom plates 403 are provided on the surfaces of the moving seats 402. Electric telescopic rods 404 are provided on the tops of the bottom plates 403. Support seats 405 are provided on the surfaces of the electric telescopic rods 404. Support rods are provided inside the support seats 405. Balance plates 406 are rotatably provided on the surfaces of the support rods. Torsion springs 407 are provided on the surfaces of the support rods. The two ends of the torsion springs 407 are respectively fixed to the ends of the support seats 405 and the balance plates 406. Support plates 408 are provided at both ends of the balance plates 406. A protective assembly 500 is provided at the end of the support assembly 400.

[0025] When the pump body is placed inside the storage frame 200 and the pipes at its ends are being cut, in order to prevent uneven forces on both sides of the pump body from causing shaking, resulting in offset of the cutting position and affecting the cutting accuracy. Therefore, the clamping assembly includes a vertical frame 201 provided on one side of the storage frame 200. A threaded rod 202 is provided at the top of the vertical frame 201. A pressure plate 203 is provided at the end of the threaded rod 202. Rotating the threaded rod 202 drives the pressure plate 203 to move in the vertical direction. When the pump is placed inside the storage frame 200, by rotating the threaded rods 202 on both sides of the storage frame 200, the pressure plates 203 are driven to move in the vertical direction. Since the surface of the pump body is uneven, by adjusting the pressing heights of the pressure plates 203 on both sides, the pump body can be fixed, the stability of the pump body can be improved, and the shaking of the pump body during the cutting process can be avoided, thus affecting the cutting accuracy.

[0026] When cutting the pipes at the end of the pump body, when the operator performs the cutting, the high-temperature debris generated is likely to cause burns, and the labor intensity during the cutting process is high. Therefore, the cutting assembly 300 includes a first cylinder 301 provided at the top of the extension plate 106. The piston rod at the end of the first cylinder 301 penetrates through the extension plate 106 and a moving frame 302 is provided at its end. The moving frame 302 is hollow. A cutting machine 303 is provided below the moving frame 302. A rotating rod at the top of the cutting machine 303 penetrates through the moving frame 302 to its interior. A turbine 306 is provided at the end of the rotating rod. A servo motor 304 is provided at the end of the moving frame 302. The output end of the servo motor 304 penetrates through the moving frame 302 and a worm 305 is provided at its end. The worm 305 is meshed with the turbine 306. When it is necessary to cut the pump body, control the piston rod at the end of the first cylinder 301 to drive the moving frame 302 to move in the vertical direction. During the movement of the moving frame 302, drive the cutting machine 303 to cut the pump body pipe, reducing the labor intensity of the operator. When it is necessary to adjust the cutting angle, control the servo motor 304 to drive the worm 305 to rotate. When the worm 305 rotates, drive the turbine 306 to rotate meshingly. When the turbine 306 rotates, drive the cutting machine 303 to rotate coaxially, thereby adjusting the cutting angle of the pump body, thus improving the practicability of the cutting device.

[0027] When cutting the pipes on both sides of the pump body, since the pipes are in a suspended state, vibration is likely to occur during the cutting process, resulting in a reduction in cutting accuracy. Therefore, substrates 307 are provided on both sides of the cutting machine 303. A column cylinder 308 is provided at the bottom of the substrate 307. A sliding rod 309 is slidably provided on the inner wall of the column cylinder 308. An elastic member 310 is provided between the column cylinder 308 and the sliding rod 309. A pressing plate 311 is provided at the bottom of the sliding rod 309. When the cutting machine 303 moves downward in the vertical direction, the pressing plate 311 first contacts the pipe. The pressing plate 311 drives the sliding rod 309 to slide on the inner wall of the column cylinder 308 under the extrusion force of the pump body. At the same time, the sliding rod 309 presses the elastic member 310. Since the pressing plate 311 is symmetric, during the cutting of the pump body, both sides of the cutting position are pressed, reducing the vibration at the suspended part of the pipe, thereby improving the cutting accuracy.

[0028] During the cutting process of the pipes on both sides of the pump body, in order to avoid sand and gravel particles remaining on the pipe surface, which may cause the cutter of the cutting machine 303 to break during the cutting process and affect the service life of the cutting machine 303. Therefore, a sponge pad 312 is provided at the bottom of the pressing plate 311. When the sponge pad 312 moves on the pipe surfaces on both sides of the pump body, it removes the surface particles and dust. When no cutting operation is performed, the control unit drives the output end of the first cylinder 301 to drive the moving frame 302 to move downward in the vertical direction, so that the sponge pad 312 provided below the moving frame 302 fits the surface of the pump body. By sliding the sliding frame 102 on the surface of the guide rail frame 101, the sponge pad 312 sweeps the pipe surface, causing the sand and gravel particles attached to the pipe surface to fall off, thereby avoiding the cutter of the cutting machine 303 from breaking during the cutting process and improving the service life of the cutting machine 303.

[0029] When the cutting of the pipes on both sides of the pump body is completed, the cutting material drops. Since the cutting material is heavy, it is likely to cause deformation of the workbench 100 during the dropping process, affecting the subsequent use of the workbench 100. Moreover, the dropped cutting material is likely to roll, causing potential safety hazards. Therefore, the support assembly 400 includes electric guide rails 401 provided on both sides of the storage frame 200. A moving seat 402 is slidably provided on the surface of the electric guide rail 401. A bottom plate 403 is provided on the surface of the moving seat 402. An electric telescopic rod 404 is provided on the top of the bottom plate 403. A support seat 405 is provided on the surface of the electric telescopic rod 404. A support rod is provided inside the support seat 405. A balance plate 406 is rotatably provided on the surface of the support rod. Support plates 408 are provided at both ends of the balance plate 406. During the cutting operation, by controlling the movement of the moving seat 402 on the surface of the electric guide rail 401, the moving seat 402 drives the bottom plate 403 to move horizontally. When the balance plate 406 provided above the bottom plate 403 moves to the position below the cutting center, by controlling the electric telescopic rod 404 to drive the support seat 405 to move in the vertical direction, the support plates 408 provided on both sides of the balance plate 406 are made to fit the bottom of the pump body pipe. When cutting the pump body, since the distance between the pressing plates 311 provided on both sides of the cutting machine 303 is the same as the distance between the support plates 408, when the cutting machine 303 drives the pressing plates 311 to move downward for cutting, the pressing plates 311 are in extrusion cooperation with the support plates 408. When the pump body cutting material is severed, it is subjected to the clamping force between the pressing plates 311 and the support plates 408, thereby ensuring that the cutting material is fixed at the cutting position, thus avoiding the direct dropping of the cutting material and preventing potential safety hazards.

[0030] During the cutting process of the pipe at the end of the pump body, in order to avoid the splashing of slag particles generated by cutting from polluting the environment, therefore, the protection component 500 includes a support block 501 provided at the end of the workbench 100. A long rod is provided between the support blocks 501. Gears 503 are provided on both sides of the long rod. A baffle 502 is provided between the gears 503. A second cylinder 504 is provided on one side of the baffle 502. A push plate 505 is provided at the end of the piston rod of the second cylinder 504. A rack 506 is provided at the end of the push plate 505. The rack 506 moves at the bottom of the gear 503. During cutting, by controlling the piston rod at the end of the second cylinder 504 to drive the push plate 505 to move in the axial direction, the rack 506 is driven to move during the movement of the push plate 505. When the rack 506 moves to the bottom of the gear 503, the movement of the rack 506 drives the gear 503 to mesh and rotate, so that the baffle 502 rotates to the vertical position to block the end face of the cutting position and avoid the slag particles generated during the cutting process from polluting the environment.

[0031] During specific use, when the pump body is placed inside the storage frame 200, by rotating the threaded rods 202 on both sides of the storage frame 200, the pressure plates 203 are driven to move in the vertical direction. Since the surface of the pump body is uneven, by adjusting the pressing heights of the pressure plates 203 on both sides, the fixation of the pump body is ensured, the stability of the pump body is improved, and the shaking of the pump body during the cutting process is avoided from affecting the cutting accuracy. By controlling the moving seat 402 to move on the surface of the electric guide rail 401, the moving seat 402 drives the bottom plate 403 to move in the horizontal direction. When the balance plate 406 provided above the bottom plate 403 moves to below the cutting center position, by controlling the electric telescopic rod 404 to drive the support seat 405 to move in the vertical direction, the support plates 408 provided on both sides of the balance plate 406 are made to fit the bottom of the pump body pipe. When the pump body is cut, since the distance between the pressure plates 311 provided on both sides of the cutting machine 303 is the same as the distance between the support plates 408, therefore, when the cutting machine 303 drives the pressure plates 311 to move downward for cutting, the pressure plates 311 are made to be in extrusion fit with the support plates 408. When the cutting material of the pump body is separated, due to the clamping force between the pressure plates 311 and the support plates 408, the cutting material is ensured to be fixed at the cutting position, thereby avoiding the direct dropping of the cutting material and improving the safety of the cutting operation. By controlling the piston rod at the end of the second cylinder 504 to drive the push plate 505 to move in the axial direction, the rack 506 is driven to move during the movement of the push plate 505. When the rack 506 moves to the bottom of the gear 503, the movement of the rack 506 drives the gear 503 to mesh and rotate, so that the baffle 502 rotates to the vertical position to block the end face of the cutting position and avoid the slag particles generated during the cutting process from polluting the environment. Control the piston rod at the end of the first cylinder 301 to drive the moving frame 302 to move in the vertical direction. During the movement of the moving frame 302, drive the cutting machine 303 to cut the pump body pipeline, reducing the labor intensity of the operators. When it is necessary to adjust the cutting angle, control the servo motor 304 to drive the worm 305 to rotate. When the worm 305 rotates, drive the turbine 306 to engage and rotate. When the turbine 306 rotates, drive the cutting machine 303 to rotate coaxially, so as to adjust the cutting angle of the pump body, thereby improving the practicability of the cutting device.

When the pump is placed inside the placement frame 200, rotate the threaded rods 202 on both sides of the placement frame 200 to drive the pressing plates 203 to move in the vertical direction, and press and fix the top of the pump body by adjusting the pressing heights of the pressing plates 203 on both sides; S2. Control the moving seat 402 to move on the surface of the electric guide rail 401. The moving seat 402 drives the bottom plate 403 to move in the horizontal direction. When the balance plate 406 provided above the bottom plate 403 moves to below the cutting center position, control the electric telescopic rod 404 to drive the support seat 405 to move in the vertical direction, so that the support plates 408 provided on both sides of the balance plate 406 are attached to the bottom of the pump body pipeline. When the cutting machine 303 drives the pressing plate 311 to move downward for cutting, make the pressing plate 311 and the support plate 408 be in extrusion cooperation; S3. Control the piston rod at the end of the second cylinder 504 to drive the push plate 505 to move in the axial direction. During the movement of the push plate 505, drive the rack 506 to move. When the rack 506 moves to the bottom of the gear 503, the movement of the rack 506 drives the gear 503 to engage and rotate, so that the baffle 502 rotates to the vertical position to block the end face of the cutting position; S4. Control the piston rod at the end of the first cylinder 301 to drive the moving frame 302 to move in the vertical direction. During the movement of the moving frame 302, drive the cutting machine 303 to cut the pump body pipeline.
