Description

Technical Field

[0001] This invention relates to the field of butterfly valve manufacturing and processing technology, specifically to an intelligent manufacturing and processing equipment for pressure-reducing butterfly valves. Background Technology

[0002] Pressure-reducing butterfly valves are special industrial valves that integrate the on / off regulation function of butterfly valves with the pressure-reducing and stabilizing function of pressure-reducing valves. The core function is to throttle and reduce the pressure of pipeline media by adjusting the opening degree of the rotatable butterfly valve plate. It can stabilize the fluctuating high pressure medium upstream to the low pressure condition set downstream. At the same time, it also has the ability to control the medium on / off and finely regulate the flow. Compared with the traditional separate combination of "pressure reducing valve + gate valve", it has the advantages of compact structure, small installation space, low flow resistance, fast opening and closing response, and convenient operation and maintenance. It is widely used in various media pressure control scenarios such as municipal water supply and drainage, HVAC, petrochemical, and power grid.

[0003] Refer to the relevant patent CN119016762A. Its essence is that the workpiece is clamped and intermittently indexed and rotated for positioning by a cylinder and servo motor. The magnetic block is used to magnetically attract and spring to reset the sliding plug, which reciprocates. Cooling water is supplied to the drilling and grinding processes simultaneously. Then, through the contact switching circuit between the conductive rod and the conductive block, the alternation between drilling and grinding processes is automatically completed. The continuous automated processing of valve even hole distribution and hole edge deburring can be achieved without manual intervention. This ensures that the hole distribution is uniform and extends the service life of the drill rod and grinding block, realizing multi-process integrated high-efficiency operation.

[0004] The current processing of pressure-reducing butterfly valve bodies mostly adopts a step-by-step operation mode. The valve body blank needs to be clamped and fixed manually before drilling a hole in a single position. After completing one section of processing, the workpiece needs to be disassembled manually, the clamping angle adjusted or the processing station changed before processing other parts such as mounting shaft holes and double-sided flange holes. At the same time, the debris generated during processing needs to be cleaned by separate dust removal equipment or manually. Furthermore, there is no simultaneous deburring process after drilling, requiring an additional grinding station.

[0005] The inconveniences of this processing method are as follows: repeated clamping can easily cause positioning deviations, leading to excessive dimensional and positional tolerances of the valve body holes, affecting the valve's sealing performance and pressure reduction and stabilization accuracy; there are many manual intervention steps, resulting in low production efficiency, and human error can easily cause processing defects, increasing the product defect rate; the collection of debris is not synchronized with processing, and flying debris can easily scratch the workpiece surface and jam the processing mechanism, and manual cleaning is time-consuming, labor-intensive, and pollutes the environment; the drilling and grinding processes are separated, requiring additional investment in equipment and manpower, resulting in high manufacturing costs, and the time spent switching processes further reduces production efficiency; some existing equipment lacks a precise multi-degree-of-freedom adjustment mechanism, making it impossible to achieve continuous processing of the valve body in multiple positions and angles, resulting in poor adaptability;

[0006] Therefore, an integrated design that combines precision clamping and positioning, multi-degree-of-freedom continuous machining, synchronous negative pressure dust suppression, and process linkage control should be adopted to achieve continuous drilling of multiple parts of the valve body blank in a single clamping, simultaneous debris collection, reduced manual intervention, improved machining accuracy and efficiency, and reduced manufacturing costs. To this end, we provide an intelligent production and processing equipment for pressure-reducing butterfly valves to solve the above problems. Summary of the Invention

[0014] A further improvement of the technical solution of the present invention is that: a semi-circular limiting block is fixedly connected to the middle of the top surface of the bearing plate, a clamping plate is fixedly connected to one end of the top surface of the bearing plate, multiple working holes are opened inside the top surface of the bearing plate, and a hydraulic lifting rod is fixedly connected to the side of the bearing plate.

[0015] A further improvement of the technical solution of the present invention is that: a pressure plate is fixedly connected to the output end of the hydraulic lifting rod, a limit block is fixedly connected to the side of the pressure plate, the limit block is slidably connected to the top of the outer surface of the limit rod, a clamping push plate is fixedly connected to one end of the bottom surface of the pressure plate, the clamping push plate is movably connected to the outer surface of the clamping plate, and a second semi-circular limit block is fixedly connected to the middle of the bottom surface of the pressure plate, the second semi-circular limit block having the opposite orientation to the first semi-circular limit block.

[0016] A further improvement of the technical solution of the present invention is that: there are two lifting platforms, one of which has a drive structure on its side, and the other lifting platform has a limit shell fixedly connected to its side. The fixed bracket is fixedly installed at the output end of the drive structure, and the limit plate is rotatably connected inside the limit shell.

[0017] A further improvement of the technical solution of the present invention is that: the inner side of the limiting shell has two opposing locking blocks that are slidably connected.

[0020] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0021] 1. This invention provides an intelligent production and processing equipment for pressure-reducing butterfly valves. Through the coaxial linkage of the pressure plate driven by the hydraulic lifting rod and the bearing plate, as well as the division of labor and cooperation between the semi-circular limiting block and the clamping push plate, a dual positioning mechanism of "vertical clamping + radial locking" is constructed. After the valve body blank has completed the initial horizontal limiting, the downward pressing action of the pressure plate simultaneously triggers the inner wall clamping and short pipe locking, realizing the one-time locking of the workpiece in multiple dimensions in the axial, radial and circumferential directions, ensuring the absolute stability of the workpiece posture during subsequent multi-position drilling operations.

[0022] 2. This invention provides an intelligent production and processing equipment for pressure-reducing butterfly valves. By precisely rotating the fixed bracket between horizontal and vertical states, and in conjunction with the height adjustment of the lifting platform and the indexing and locking of the clamping block, an automated operation process of "one-time clamping and three-station continuous processing" is realized. After the valve body blank has completed the drilling of the installation shaft hole, the indexing and rotating mechanism is used to make the workpiece enter the double-sided flange hole processing station in sequence. No re-clamping or manual intervention is required throughout the process, thereby eliminating repeated positioning errors, improving the positional accuracy and production efficiency of multi-faceted processing, and finally realizing the convenient picking and placing of workpieces through the rapid release of the pressure plate, forming a complete processing cycle closed loop.

[0023] 3. This invention provides an intelligent production and processing equipment for pressure-reducing butterfly valves. A directional airflow field is constructed inside the base using a negative pressure fan. Combined with the inclined guidance of the guide plate and the interception and isolation by the barrier net, a three-level collaborative debris collection path is formed: "airflow guidance—gravity settling—physical barrier." Debris generated during processing actively falls onto the guide plate under negative pressure, slides down the inclined surface to the base for centralized collection, and the barrier net prevents debris from moving towards the fan side to ensure continuous and stable operation of the equipment. Finally, convenient cleaning is achieved through an openable discharge cover. Thus, real-time collection and centralized processing of debris are completed simultaneously during processing, avoiding secondary pollution and realizing integrated processing and dust removal.

[0035] The present invention will be further described in detail below with reference to embodiments:

[0036] Example 1: As Figure 1-10 As shown, the present invention provides an intelligent production and processing equipment for pressure-reducing butterfly valves, including a base plate 1 and a valve body blank 4. A dust-reducing structure 2 is provided on the top surface of the base plate 1, and a processing structure 3 for multi-position drilling is provided on the top surface of the dust-reducing structure 2. The processing structure 3 includes a base 31 fixedly installed on the top surface of the base 21, a lifting platform 32 set on the top surface of the base 31 for adjusting the processing position of the valve body blank 4, a fixed bracket 33 set inside the side of the lifting platform 32 for positioning and clamping the valve body blank 4, a side plate 35 fixedly installed on the side of the base 31, a rotating bracket 34 rotatably connected to the side of the side plate 35 for adjusting the drilling processing position, and a drilling base 36 fixedly installed on the top surface of the rotating bracket 34 for completing the drilling operation.

[0037] The base 31 has openings at both the top and bottom, and its bottom opening is connected to the dust collection structure 2. It is used to guide most of the debris generated during the processing into the dust collection structure 2 for collection. The base 31 adjusts the position of the fixed bracket 33 through two lifting platforms 32. The adjustment includes lifting movement and rotation adjustment of orientation angle.

[0038] The fixed bracket 33 is equipped with a pressure plate 315 inside. The pressure plate 315 is arranged opposite to the bearing plate 38. There are four guide blocks 310, which are divided into two groups and are respectively set on the top surface of the bearing plate 38 and the bottom surface of the pressure plate 315. Each guide block 310 has a guide slope on one side. Through the cooperation of the two groups of guide blocks 310, the initial positioning of the valve body blank 4 is achieved.

[0039] A lifting hydraulic rod 322 is fixedly connected inside the base 31. A lifting platform 32 is fixedly installed at the output end of the lifting hydraulic rod 322. A guide rod 323 is fixedly connected to the bottom surface of the lifting platform 32. The bottom end of the outer surface of the guide rod 323 is slidably connected to the inside of the base 31. A semi-circular limiting block 311 is fixedly connected to the middle of the top surface of the bearing plate 38. A clamping plate 312 is fixedly connected to one end of the top surface of the bearing plate 38. Multiple working holes 314 are opened inside the top surface of the bearing plate 38. A hydraulic lifting rod 39 is fixedly connected to the side of the bearing plate 38.

[0040] The first semicircular limiting block 311 on the top surface of the bearing plate 38 has a sloping semicircular shape. The second semicircular limiting block 318 has the same shape as the first semicircular limiting block 311 but faces the opposite direction. The two blocks work together to limit the inner wall of the valve body blank 4. The gap between the clamping plates 312 is adapted to the outer diameter of the short tube on the surface of the valve body blank 4, and a certain amount of fitting allowance is reserved to facilitate the insertion and removal of the short tube.

[0041] A pressure plate 315 is fixedly connected to the output end of the hydraulic lifting rod 39. A limit block 316 is fixedly connected to the side of the pressure plate 315. The limit block 316 is slidably connected to the top of the outer surface of the limit rod 313. A clamping push plate 317 is fixedly connected to one end of the bottom surface of the pressure plate 315. The clamping push plate 317 is movably connected to the outer surface of the clamping plate 312. A semi-circular limit block 318 is fixedly connected to the middle of the bottom surface of the pressure plate 315. The semi-circular limit block 318 is opposite to the orientation of the semi-circular limit block 311.

[0042] The clamping push plate 317 has a guide slope inside, which cooperates with the outer surface of the clamping plate 312. When the pressure plate 315 is pressed down, it can apply a radial clamping force to the clamping plate 312, thereby further limiting the short pipe part of the valve body blank 4. Both the bearing plate 38 and the pressure plate 315 have multiple working holes 314 inside. The position of each working hole 314 corresponds one-to-one with the position of the flange hole to be processed on the valve body blank 4, so that the drill bit of the drilling machine 321 can pass smoothly and process the valve body blank 4.

[0043] In this embodiment, when the fixed bracket 33 and its related components are in a horizontal state, the hydraulic lifting rod 39 lifts the pressure plate 315, and under the guidance of the limiting rod 313, the pressure plate 315 and the bearing plate 38 are always kept on the same axis. At this time, the valve body blank 4 is placed on the top surface of the bearing plate 38, and its short tube is pushed into the gap of the clamping plate 312. When the bearing plate 38 is pushed to the designated position, the short tube of the valve body blank 4 is inserted into the interior of the clamping plate 312, and at the same time, the semi-circular limiting block 311 is inserted into the inner wall of the valve body blank 4, completing the initial positioning.

[0044] Subsequently, the hydraulic lifting rod 39 drives the pressure plate 315 to press down onto the top surface of the valve body blank 4. The semi-circular limiting blocks 311 and 318, which are oriented in opposite directions, clamp and position the valve body blank 4 from both the inside and outside, ensuring the stability of the valve body blank 4 during processing. At the same time, the clamping push plate 317 presses against the clamping plate 312, applying radial clamping force to the short tube section of the valve body blank 4, further enhancing the reliability of positioning.

[0045] Example 2: As Figure 1-10 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, there are two lifting platforms 32, one of which has a drive structure on its side, and the other lifting platform 32 has a limiting housing 328 fixedly connected to its side. A fixed bracket 33 is fixedly installed at the output end of the drive structure. A limiting plate 37 is rotatably connected inside the limiting housing 328. Two opposing locking blocks 327 are slidably connected inside the limiting housing 328. The locking blocks 327 are locked onto the side of the limiting plate 37. A hydraulic rod 325 is fixedly connected to the top of the side of the limiting housing 328. A synchronization plate 326 is fixedly connected to the output end of the hydraulic rod 325. One end of the outer surface of the locking block 327 penetrates the side of the limiting housing 328 and is slidably connected inside the synchronization plate 326.

[0046] Two lifting platforms 32 are raised and lowered synchronously under the drive of the lifting hydraulic rod 322, and their movement trajectory is kept stable under the limiting action of the guide rod 323. One of the lifting platforms 32 has a drive structure on its side, which is composed of a reduction gear and a motor. One end of the fixed bracket 33 is fixedly connected to the output end of the drive structure, which is used to drive the fixed bracket 33 to rotate and adjust.

[0047] Another lifting platform 32 has a limiting housing 328 fixedly connected to its side. The limiting housing 328 has a groove inside for accommodating a locking block 327. A limiting plate 37 is rotatably connected inside the limiting housing 328. The limiting plate 37 has four slots on its side, corresponding to the positioning positions of the fixed bracket 33 in the horizontal, vertical, and 90° and 180° rotation states, respectively. Driven by a hydraulic rod 325, the locking block 327 moves synchronously via a synchronizing plate 326. By engaging the slots on the side of the limiting plate 37, it precisely limits the rotation angle of the fixed bracket 33. This structure allows the fixed bracket 33 to achieve 90° interval rotational positioning, ensuring angular accuracy when switching between horizontal and vertical states.

[0048] The side of the punching base 36 is provided with a sliding groove 324. The bottom surface of the rotating bracket 34 is fixedly connected to a limiting slide rod 319. The limiting slide rod 319 is slidably connected inside the sliding groove 324. The inside of the punching base 36 is rotatably connected to a threaded rod 320. The top surface of the punching base 36 is slidably connected to a punching machine 321. The threaded rod 320 is threadedly connected inside the punching machine 321.

[0049] A power structure consisting of a gearbox and a motor is provided on the back of the side plate 35. The rotating bracket 34 is fixedly connected to the output end of the power structure and can rotate around the side of the side plate 35 under the drive of the power structure. The limiting slide rod 319 is slidably connected inside the slide groove 324 opened on the side of the side plate 35, and together with the rotating bracket 34, it forms an approximately triangular support structure. This structure can effectively improve the rigidity of the rotating bracket 34 in the working state and ensure the stability of the drilling operation.

[0050] The inner side of the drilling base 36 is provided with a power structure that can drive the threaded rod 320 to rotate. The threaded rod 320 is threadedly engaged with the drilling machine 321. The rotation of the threaded rod 320 can drive the drilling machine 321 to make stable linear motion along the top surface of the drilling base 36, thereby realizing the drilling feed and retraction actions.

[0051] In this embodiment, after the valve body blank 4 is clamped and fixed, the threaded rod 320 drives the drilling machine 321 to slowly advance, completing the first drilling operation on the mounting shaft part of the valve body blank 4 before resetting. Subsequently, the hydraulic rod 325 drives the synchronous plate 326 to descend, causing the two locking blocks 327 to disengage from the limiting plate 37. At this time, the drive motor on the side of the lifting platform 32 drives the fixed bracket 33 to rotate 90° to a vertical position. The hydraulic rod 325 then drives the locking blocks 327 to engage with the corresponding slots of the limiting plate 37, completing the positioning after rotation.

[0052] Next, the lifting hydraulic rod 322 drives the lifting platform 32 to raise or lower the vertically fixed bracket 33, aligning the flange hole to be processed with the drilling machine 321 on the rotating bracket 34 on the same axis. At this point, the output end of the drilling machine 321 is aligned with the flange hole to be processed on the valve body blank 4, and, driven by the threaded rod 320, passes through the working hole 314, completing the processing of one side of the flange hole. Subsequently, the lifting platform 32 drives the fixed bracket 33 to rotate 180° again, repeating the above steps to complete the processing of the flange hole on the other side.

[0053] After all drilling operations are completed, the fixed bracket 33 returns to a horizontal position, and the hydraulic lifting rod 39 drives the pressure plate 315 to rise and release the restriction on the valve body blank 4. The operator only needs to slightly lift the short tube end of the valve body blank 4 and push it forward to quickly remove the valve body blank 4 from the support plate 38, completing a complete processing cycle.

[0054] Example 3: As Figure 1-10 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the dust suppression structure 2 includes a base 21 fixedly installed on the top surface of the base plate 1, a guide plate 22 fixedly installed on the top surface of the base 21 to reduce debris splashing, and a negative pressure fan 25 disposed inside the side of the guide plate 22 to provide negative pressure to guide airflow. The guide plate 22 is disposed inside the bottom surface of the base 31. An output port is opened on the side of the base 21. A discharge cover plate 23 is movably connected to the output port of the base 21 through a hinge. A barrier net 24 is fixedly connected to one end of the interior of the base 21.

[0055] The guide plate 22 is located inside the base 31, with an opening at one end communicating with the interior of the base 21. Two negative pressure fans 25 are installed at one end of the base 21; the simultaneous operation of both fans ensures sufficient negative pressure, guaranteeing effective suction of debris. An obstruction mesh 24 is installed inside the guide plate 22. This obstruction mesh 24 is arranged at an angle to intercept large debris particles as the negative pressure airflow passes through. The angled arrangement also reduces debris accumulation on the mesh surface, preventing blockages that could affect the negative pressure effect. A sealing strip is installed at the connection between the discharge cover 23 and the base 21, ensuring relative sealing of the base 21 when closed, thereby maintaining the operating efficiency of the negative pressure fans 25.

[0056] In this embodiment, when the dust-collecting structure 2 is in operation, two negative pressure fans 25 work simultaneously, forming a stable negative pressure area inside the base 31. Most of the debris generated during processing falls downwards onto the top surface of the guide plate 22 under the guidance of the negative pressure airflow, and then slides down the inclined surface of the guide plate 22 into the interior of the base 21 for collection. The barrier net 24 effectively prevents debris from moving further towards the negative pressure fans 25, avoiding debris entering the fans and affecting their normal operation. After the operation is completed, the operator can open the discharge cover 23 to clean the debris collected inside the base 21, preventing impurities from scattering throughout the working area.

[0057] The working principle of this intelligent production and processing equipment for pressure-reducing butterfly valves will be explained in detail below.

[0058] like Figure 1-10 As shown, when the fixed bracket 33 and its supporting components are in a horizontal state, the hydraulic lifting rod 39 lifts the pressure plate 315, and the pressure plate 315 remains coaxial with the bearing plate 38 under the guidance of the limiting rod 313. At this time, the valve body blank 4 is placed on the top surface of the bearing plate 38, and the valve body blank 4 is pushed so that its short tube is pushed into the gap of the clamping plate 312. When it reaches the designated position, the short tube of the valve body blank 4 is locked into the clamping plate 312, and at the same time, the semi-circular limiting block 311 is locked into the inner wall of the valve body blank 4, completing the initial positioning of the workpiece.

[0059] Subsequently, the hydraulic lifting rod 39 drives the pressure plate 315 to press down onto the top surface of the valve body blank 4. The semi-circular limiting block 1 311 and semi-circular limiting block 2 318, which are set opposite to each other, clamp and position the valve body blank 4 from the inside and outside sides to ensure the stability of the workpiece during processing. At the same time, the clamping push plate 317 cooperates with the clamping plate 312 to apply radial clamping force to the short pipe part of the valve body blank 4, further improving the positioning reliability.

[0060] After the valve body blank 4 is clamped and fixed, the threaded rod 320 drives the drilling machine 321 to feed, completing the first drilling operation at the mounting shaft part of the valve body blank 4 and then resetting. Subsequently, the hydraulic rod 325 drives the synchronous plate 326 to descend, causing the two locking blocks 327 to disengage from the locking limit of the limiting plate 37; the drive motor on the side of the lifting platform 32 drives the fixed bracket 33 to rotate 90° to a vertical position, and the hydraulic rod 325 drives the locking blocks 327 to engage with the corresponding slots of the limiting plate 37, completing the positioning and locking after rotation.

[0061] Next, the lifting hydraulic rod 322 drives the lifting platform 32 to adjust the vertical fixed bracket 33, making the flange hole to be processed on the valve body blank 4 coaxial with the drilling machine 321 on the rotating bracket 34. The output end of the drilling machine 321 is aligned with the flange hole to be processed, and under the drive of the threaded rod 320, it passes through the working hole 314 to complete the processing of the flange hole on one side of the valve body. Then, the fixed bracket 33 drives the workpiece to rotate 180° again, and the above steps are repeated to complete the processing of the flange hole on the other side.

[0062] During the above processing operations, the two negative pressure fans 25 work synchronously, forming a stable negative pressure area inside the base 31. The processing debris, guided by the negative pressure airflow, falls onto the top surface of the guide plate 22 and slides down its inclined surface into the base 21 for collection. The barrier net 24 effectively prevents debris from moving towards the negative pressure fans 25, avoiding debris entering the fans and affecting their normal operation. After all operations are completed, the operator can open the discharge cover 23 to clean the debris collected inside the base 21, preventing impurities from scattering into the work area.

[0063] In summary, after the valve body blank 4 is precisely clamped in a horizontal state using the fixed bracket 33, the multi-degree-of-freedom linkage between the lifting platform 32 and the rotating bracket 34 enables continuous drilling of the mounting shaft hole and the double-sided flange holes at multiple positions without interrupting the clamping. Simultaneously, the dust collection structure 2 operates synchronously with the processing action, using negative pressure airflow to form a directional collection field in the processing area, guiding and collecting debris as it is generated, thus avoiding secondary pollution. The functional coupling and temporal coordination between these structures enable this application to achieve a complete "positioning-processing-dust removal" process within a single workstation, solving the problems of low efficiency and precision loss caused by multi-step operations in existing technologies.

[0064] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
