Description

Technical Field

[0001] This utility model belongs to the field of valve block production technology, specifically a valve block processing and adjustment device. Background Technology

[0002] The valve block is a core component of a hydraulic or pneumatic system. Its function is to integrate multiple hydraulic valves into a metal block and realize the distribution, control and regulation of fluid through internal oil passages or air passages.

[0003] Valve blocks are typically long, thin metal blocks. During the manufacturing process, the raw materials need to be cast and then ground and drilled to obtain the specific shape of the valve block. Before grinding and drilling, sandblasting is required to remove impurities such as oil, rust, oxide layer, and welding residue from the surface of the valve block, providing a clean base for subsequent processing. The uniform impact of the sand particles can also reduce surface scratches, decrease the risk of stress concentration, and extend the fatigue life of the valve block.

[0004] During the sandblasting process, the distance between the spray gun and the valve block affects the diffusion range and impact energy of the sand particles. Therefore, different heights are required for valve blocks made of different materials. Existing spray guns are usually fixed in a certain position, which has poor adaptability.

[0005] Therefore, this utility model provides a valve block processing and adjustment device. Utility Model Content

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4As shown in the embodiment of this utility model, a valve block processing and adjusting device includes a base 1; a frame 2 is fixedly connected to the top of the base 1; a sand storage tank 3 is fixedly connected to the top of the frame 2; multiple conveying pipes 4 are fixedly connected to the bottom of the sand storage tank 3; the conveying pipes 4 are located inside the frame 2; a spray gun 5 is fixedly connected to the end of the conveying pipe 4; the spray gun 5 is inclined; a conveying assembly is installed in the middle of the base 1; the conveying assembly is used to convey materials, and the conveying assembly includes a drive motor 7, a perforated conveyor belt 6, and rollers; A drive motor assembly 7 is fixedly connected to the side wall of the machine base 1; the roller is mounted on the drive motor assembly 7 and positioned between the machine bases 1; a perforated conveyor belt 6 is mounted on the roller; a sand collection box 8 is fixedly connected to the machine base 1; the sand collection box 8 is positioned below the perforated conveyor belt 6; a hydraulic cylinder 9 is fixedly connected to the top of the frame 2; the output end of the hydraulic cylinder 9 passes through the side wall of the frame 2 and is fixedly connected to a fixing plate 10; a connecting plate 11 is fixedly connected to the end of the fixing plate 10; the middle part of the conveying pipe 4 is fixedly connected to the side wall of the connecting plate 11; the conveying pipe 4 is made of rubber. During operation, the operator places the valve block to be sandblasted and polished onto the perforated conveyor belt 6. Driven by the drive motor 7, the rollers move the perforated conveyor belt 6. At this time, the valve block above the perforated conveyor belt 6 moves towards the frame 2. By controlling the switch, the sand inside the sand storage tank 3 is sprayed out from the end of the spray gun 5 through the conveyor pipe 4. The valve block, which slowly moves under the frame 2, achieves burr removal by the collision of sand particles. Finally, the valve block exits from the other side. The processed sand particles are fed out from one end and fall through the holes on the surface of the perforated conveyor belt 6 to the bottom. When it is necessary to process valve blocks of different materials, the power switch of the hydraulic cylinder 9 is controlled according to the requirements, so that the hydraulic cylinder 9 drives the fixed plate 10 to move up and down. At this time, through the connection between the fixed plate 10 and the connecting plate 11, the connecting plate 11 drives the spray gun 5 to move up and down. By adjusting the distance between the spray gun 5 and the valve block, the sandblasting diffusion range and impact force are controlled, thereby adapting to the processing requirements of valve blocks of different materials and increasing the adaptability of this device.

[0024] like Figures 1 to 4 As shown, multiple elastic pull ropes 12 are fixedly connected to the top of the inner side wall of the frame 2; a collar 13 is fixedly connected to the end of the elastic pull rope 12; the collar 13 is sleeved and fixedly connected to the middle of the conveying pipe 4; a limit rod 14 is fixedly connected between adjacent collars 13. During operation, when the height of the spray gun 5 is adjusted and raised, the conveying pipe 4 may bend, causing multiple conveying pipes 4 to become entangled and shake and collide. At this time, the collar 13 fixes the middle of the conveying pipe 4. When the spray gun 5 moves upward, the conveying pipe 4 appears, and under the elastic action of the elastic pull rope 12, the conveying pipe 4 will be pulled, and with the cooperation of the limit rod 14, the problem of entanglement and collision between the conveying pipes 4 is reduced.

[0025] like Figures 1 to 4 As shown, a servo motor 15 is fixedly connected to the side wall of the base 1; a cleaning roller 16 is fixedly connected to the output end of the servo motor 15; the cleaning roller 16 is located between the sand collection box 8 and the perforated conveyor belt 6; the surface of the cleaning roller 16 and the surface of the perforated conveyor belt 6 are in contact with each other. During operation, by turning on the switch of the servo motor 15, the servo motor 15 drives the cleaning roller 16 to rotate. Because the surfaces of the cleaning roller 16 and the perforated conveyor belt 6 are in contact with each other, the cleaning roller 16 cleans the surface of the perforated conveyor belt 6, removing the sand particles that are still attached to the surface, thereby improving the cleanliness of the surface of the perforated conveyor belt 6 and making the conveying and processing of the valve block more stable.

[0026] like Figures 1 to 4 As shown, a filter screen 17 is fixedly connected to the middle of the sand recovery box 8. During operation, by setting the filter screen 17 on the sand recovery box 8, larger metal particles that have been cleaned out of the sand can be filtered out, so that the quality of the sand particles is better when they are subsequently recycled.

[0027] like Figure 2 As shown, a roller 18 is rotatably connected to the end of the fixed plate 10. The roller 18 is located on the end of the fixed plate 10 away from the connecting plate 11. During operation, by fitting the surface of the roller 18 against the inner wall of the frame 2, the hydraulic cylinder 9 can make the force on the fixed plate 10 more uniform when pushing the fixed plate 10 to move, and make the connection plate 11 more stable when moving up and down. In addition, the rotational design of the roller 18 reduces the frictional wear of the fixed plate 10.

[0028] like Figure 2 As shown, a stack of dustproof curtains 19 are fixed to the bottom of the frame 2; the dustproof curtains 19 are symmetrically arranged on the frame 2. During operation, by setting the dustproof curtains 19 on both sides of the frame 2, the problem of sand particle splashing during sandblasting can be reduced, and the safety of the working environment can be improved.

[0029] Working principle: The operator places the valve block to be sandblasted and polished onto the perforating conveyor belt 6. Driven by the drive motor 7, the rollers move the perforating conveyor belt 6. At this time, the valve block above the perforating conveyor belt 6 moves towards the frame 2. By controlling the switch, the sand inside the sand storage tank 3 is sprayed out from the end of the spray gun 5 through the conveying pipe 4. The valve block, which slowly moves under the frame 2, achieves burr removal by the collision of sand particles. Finally, the valve block is sent out from the other end. The processed sand particles will fall through the holes on the surface of the perforated conveyor belt 6 to the bottom. When it is necessary to process valve blocks of different materials, the power switch of the hydraulic cylinder 9 is controlled according to the requirements, so that the hydraulic cylinder 9 drives the fixed plate 10 to move up and down. At this time, through the connection between the fixed plate 10 and the connecting plate 11, the connecting plate 11 drives the spray gun 5 to move up and down. By adjusting the distance between the spray gun 5 and the valve block, the sandblasting diffusion range and impact force are controlled, thereby adapting to the processing requirements of valve blocks of different materials and increasing the adaptability of this device.

[0030] When the height of the spray gun 5 is adjusted and raised, the delivery pipe 4 may bend, causing multiple delivery pipes 4 to become entangled and collide. At this time, the middle of the delivery pipe 4 is fixed by the collar 13. When the spray gun 5 moves upward, the delivery pipe 4 appears. Under the elastic action of the elastic rope 12, the delivery pipe 4 will be pulled. With the cooperation of the limit rod 14, the problem of entanglement and collision between the delivery pipes 4 is reduced.

[0031] By turning on the switch of the servo motor 15, the servo motor 15 drives the cleaning roller 16 to rotate. Because the surface of the cleaning roller 16 and the perforated conveyor belt 6 are in contact with each other, the cleaning roller 16 cleans the surface of the perforated conveyor belt 6, removing the sand particles that are still attached to the surface, thereby improving the cleanliness of the surface of the perforated conveyor belt 6 and making the conveying and processing of the valve block more stable.

[0032] By installing a filter screen 17 on the sand recovery box 8, larger metal particles that have been removed from the sand can be filtered out using the filter screen 17, resulting in better quality sand when it is subsequently recycled.

[0033] By fitting the roller 18 surface to the inner wall of the frame 2, the hydraulic cylinder 9 can make the fixed plate 10 more evenly stressed when pushing the fixed plate 10 to move, and make the connecting plate 11 more stable when moving up and down. In addition, the roller 18 rotation design reduces the frictional wear of the fixed plate 10.

[0034] By installing dustproof curtains 19 on both sides of the frame 2, the problem of sand particle splashing during sandblasting can be reduced, and the safety of the working environment can be improved.
