Description

Technical Field

[0001] This invention relates to a butterfly plate frame production equipment, specifically a production equipment for butterfly valve butterfly plate frames. Background Technology

[0002] As a commonly used fluid control valve, the butterfly valve's disc holder is a core load-bearing component that directly affects the valve's sealing performance, structural stability, and service life. Sandblasting is a crucial process in the manufacturing of the butterfly valve disc holder. Its main function is to remove impurities such as oxide scale, rust, burrs, and oil from the disc holder's surface, improving its surface roughness and laying the foundation for subsequent painting and welding processes, thus ensuring the disc holder's machining accuracy and reliability.

[0003] Currently, existing sandblasting equipment for butterfly valve plate holders has many shortcomings, making it difficult to meet the needs of efficient and comprehensive sandblasting processing. First, most existing equipment cannot achieve continuous rotation of the plate holder, and sandblasting operations can only process fixed areas of the plate holder. This results in uneven sandblasting on the plate holder surface, and some dead corner areas cannot be effectively treated, seriously affecting the sandblasting quality, and consequently affecting the processing effect of subsequent processes and the final performance of the plate holder.

[0004] Secondly, the sandblasting pipes in existing equipment are mostly fixed in position, making it impossible to flexibly adjust their distance from the butterfly plate frame or their lateral position. When processing butterfly plate frames of different specifications and sizes, the inability to adjust the position of the sandblasting pipes according to actual processing needs leads to either insufficient sandblasting force and incomplete removal of impurities, or excessive sandblasting that damages the surface of the butterfly plate frame, reducing the product qualification rate. This also limits the versatility of the equipment and increases production costs.

[0005] In addition, the sandblasting pipes of existing sandblasting equipment are mostly fixed in orientation, and can only perform sandblasting operations in a single direction. They cannot achieve swing sandblasting, which further aggravates the problem of uneven sandblasting. It is difficult to ensure that the sandblasting effect of each part of the butterfly plate frame is consistent, and cannot meet the production requirements of high-precision butterfly valve butterfly plate frames. Summary of the Invention

[0006] The purpose of this invention is to provide a production equipment for butterfly valve plate holders to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A production equipment for a butterfly valve plate frame includes a processing box and a support frame. The support frame is fixedly connected to the bottom of the processing box. A support component is fixedly connected inside the processing box. Several support components for supporting the butterfly plate frame are arranged above the support component. A sandblasting component is arranged on the side of the processing box. The sandblasting component includes several sandblasting pipes. The ends of the sandblasting pipes are located on the side of the support component. An adjustment component for adjusting the position of the sandblasting pipe ends is also arranged on the side of the processing box.

The driving bevel gears mesh with the driven bevel gears, and the motor output shaft is connected to the first rotating shaft through a gear set transmission.

[0012] As a further embodiment of the present invention: all the sandblasting pipes are fixedly connected to the adjustment component, the adjustment component is horizontally slidably connected to the side wall of the processing box, and the adjustment component moves closer to or further away from the butterfly plate frame when sliding. The outer side wall of the processing box is also fixedly connected to a first telescopic rod that drives the adjustment component to move.

[0013] As a further embodiment of the present invention: the adjustment assembly includes a sleeve and a slide rod, the sandblasting pipe is fixedly connected to the slide rod, and a second telescopic rod is fixedly connected to the side of the sleeve. When the second telescopic rod extends or retracts, it drives the slide rod to extend or retract inside the sleeve. When the slide rod slides, the position of the sandblasting pipe opening moves along the axis of the slide rod.

[0014] As a further embodiment of the present invention: a drive sleeve is fixedly connected to the end of the first telescopic rod, the drive sleeve is rotatably connected to the adjustment component, and a locking screw for locking the adjustment component is also fixedly connected to the outside of the drive sleeve.

[0015] As a further embodiment of the present invention: a second rotating shaft is rotatably connected to the side wall of the processing box, and an axially distributed lever is fixedly connected to the outside of the second rotating shaft. When the lever rotates, it presses against the sandblasting pipe. The sandblasting pipe swings around the central axis of the adjustment component under the action of the lever. The second rotating shaft is connected to the motor drive.

[0016] As a further embodiment of the present invention: the second rotating shaft is connected to the motor via a pulley mechanism, and a tensioning mechanism for the pulley mechanism is also provided on the side wall of the processing box.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Please refer to the attached diagram. A production device for butterfly valve plate holders includes a processing box 1 and a support frame 2. The support frame 2 is directly fixed to the bottom of the processing box 1, and its main function is to support the entire device, ensuring its stability during processing and preventing the processing accuracy of the butterfly plate holder from being affected by equipment shaking. It is suitable for long-term use in mass production in a workshop. The bottom of the processing box 1 has a funnel-shaped structure, which can collect the blasted processing medium during sandblasting for easy reuse.

[0032] Inside the processing box 1, a support component 3 is fixedly installed. This support component 3 adopts a square tube structure. Square tubes are sturdy and low-cost, meeting the economic needs of workshop production, while providing stable support. Above the support component 3, several support assemblies 4 are evenly arranged. These support assemblies 4 are components that directly hold the butterfly plate frame. Each support assembly 4 can independently support one butterfly plate frame, allowing multiple butterfly plate frames to be processed simultaneously, improving production efficiency. The square tube structure of the support component 3 also effectively prevents sandblasting media from entering the interior of the support component 3 during sandblasting, thus avoiding damage to the internal gear structure.

[0033] Specifically, the support assembly 4 includes a support shaft 9, a support plate 10, a limiting rod 12, and a magnetic structure 13. The support shaft 9 is rotatably connected to the support member 3, allowing for flexible rotation and facilitating subsequent processing of the butterfly plate frame's various surfaces. The support plate 10 is fixed to the top of the support shaft 9 and serves as the direct placement surface for the butterfly plate frame. To ensure the butterfly plate frame does not shift or wobble during placement, a limiting rod 12 is fixedly connected to the center of the upper part of the support plate 10. During use, the limiting rod 12 is inserted into the screw hole of the butterfly plate frame for quick positioning. Simultaneously, a magnetic structure 13 is installed above the support plate 10. When the butterfly plate frame is placed on the support plate 10, it firmly engages with the magnetic structure 13, further securing the butterfly plate frame and preventing displacement during processing, thus ensuring processing accuracy. This fixing method is simple to operate and saves clamping time.

[0034] To achieve the rotation of the support shaft 9, thereby driving the butterfly plate frame to rotate, a drive unit 11 is provided inside the support member 3. The drive unit 11 includes a motor 14, a first rotating shaft 15, a driving bevel gear 16, a driven bevel gear 17, and a gear set 18. The motor 14 is fixed on the processing box 1 and provides power to the entire drive unit 11, adapting to the normal power supply requirements of the workshop. The first rotating shaft 15 is fixed on the inner side of the support member 3. Several driving bevel gears 16 are evenly fixed on the outer side of the first rotating shaft 15. At the bottom of each support shaft 9, a driven bevel gear 17 is fixed. The driving bevel gears 16 and the driven bevel gears 17 mesh with each other. The output shaft of the motor 14 is connected to the first rotating shaft 15 through the gear set 18. When in operation, the motor 14 starts and drives the first rotating shaft 15 to rotate through the gear set 18. The first rotating shaft 15 then drives all the support shafts 9 to rotate synchronously through the meshing of the driving bevel gear 16 and the driven bevel gear 17, thereby driving the butterfly plate frame on the support plate 10 to rotate, realizing all-round processing of the butterfly plate frame without the need for manual flipping, saving labor costs.

[0035] To sandblast the butterfly plate frame and improve its surface finish to meet production quality requirements, a sandblasting assembly 5 is installed on the side of the processing box 1. This assembly includes several sandblasting pipes 6, with the ends of all pipes 6 aligned with the side of the support assembly 4 to ensure precise sandblasting of the butterfly plate frame. Furthermore, to accommodate the sandblasting needs of butterfly plate frames of different sizes and to ensure more uniform and consistent sandblasting, an adjustment assembly 7 is also installed on the side of the processing box 1. This assembly 7 is primarily used to adjust the position of the sandblasting pipes 6, allowing for flexible adjustment of the sandblasting angle and distance based on the size and shape of the butterfly plate frame.

[0036] The adjusting assembly 7 consists of a sleeve 20, a sliding rod 21, and a second telescopic rod 22. The sandblasting pipe 6 is fixedly connected to the sliding rod 21, and the two can be connected via a pipe connector, allowing for easy adjustment of the position of the sandblasting pipe 6 by adjusting the position of the connector. The pipe connector is similar in structure to the scaffolding fasteners used on construction sites, ensuring the sandblasting pipe 6 is stably fixed in the connection position. The second telescopic rod 22 is fixed to the side of the sleeve 20. When the second telescopic rod 22 extends or retracts, it causes the sliding rod 21 to slide back and forth inside the sleeve 20. As the sliding rod 21 slides, it causes the nozzle of the sandblasting pipe 6 to move along the axis of the sliding rod 21, thereby adjusting the distance between the sandblasting pipe 6 and the butterfly plate frame to accommodate butterfly plate frames of different thicknesses.

[0037] In addition, a first telescopic rod 19 is fixed to the outer wall of the processing box 1. A drive sleeve 23 is fixedly connected to the end of the first telescopic rod 19. The drive sleeve 23 is rotatably connected to the adjusting component 7. When the first telescopic rod 19 extends or retracts, it can drive the adjusting component 7 to slide horizontally as a whole, so that the adjusting component 7 can move the sandblasting pipe 6 closer to or away from the butterfly plate frame, further optimizing the sandblasting position. In order to fix the position of the adjusting component 7, a locking screw 24 is also installed on the outside of the drive sleeve 23. After the adjusting component 7 is adjusted to a suitable position, tightening the locking screw 24 can fix the adjusting component 7, preventing displacement during processing, ensuring sandblasting accuracy, and making the operation simple and suitable for quick operation by workshop workers. The slide rod 21 and the sleeve 20 cannot rotate relative to each other, but can only slide in a straight line. At this time, the position of the slide rod 21 can be locked by the locking screw 24 to prevent the slide rod 21 from rotating around its own axis. To achieve the oscillation of the sandblasting pipe 6, ensuring more uniform sandblasting of the butterfly plate frame and avoiding sandblasting dead zones, a second rotating shaft 25 is rotatably connected to the side wall of the processing box 1. An axially distributed lever 26 is fixed to the outer side of the second rotating shaft 25. When the lever 26 rotates, it presses against the sandblasting pipe 6, causing the sandblasting pipe 6 to oscillate around the central axis of the adjusting component 7. The second rotating shaft 25 is connected to the motor 14 via a pulley mechanism 27, eliminating the need for an additional power source and saving equipment costs. Simultaneously, a tensioning mechanism is provided on the side wall of the processing box 1 to tighten the pulley mechanism 27, preventing pulley slippage, ensuring transmission stability, reducing equipment failures, and improving production continuity. If it is necessary to fix the sandblasting position of the sandblasting pipe 6 during the sandblasting process of the butterfly plate frame, the tensioning mechanism can be loosened. At this time, the transmission chain is disconnected, the lever 26 stops rotating, and the sandblasting pipe 6 remains fixed for sandblasting.

[0038] In addition, several observation ports 8 are provided on the processing box 1. These observation ports 8 are distributed on different side walls of the processing box 1, which makes it convenient for workshop workers to observe the processing status of the butterfly plate frame and the operating status of the equipment from different angles during the processing process, so as to detect processing abnormalities or equipment failures in a timely manner, avoid the production of unqualified products, and at the same time reduce the number of times workers open the processing box 1, thereby improving production efficiency.
