Description

Technical Field

[0001] This invention belongs to the field of quenching technology, and in particular relates to a quenching device and quenching process for the production of regulating valves. Background Technology

[0002] As a key actuator in modern industrial process control systems, the performance of the core components of a control valve directly determines the reliability, sealing accuracy, and service life of the entire valve.

[0003] Chinese patent CN221837048U discloses a quenching device for regulating valve production, including a workbench, a quenching tank mounted on the workbench, an mounting frame mounted on the workbench and behind the quenching tank, an electric slide rail mounted on the lower wall of the mounting frame's crossbeam, an assembly column mounted on the moving end of the electric slide rail, an electric push rod embedded in the assembly column, an extension column mounted on the telescopic end of the electric push rod, a fixing plate mounted on the lower end of the extension column, two connecting rods mounted on the lower wall of the fixing plate, two electromagnets mounted on the lower ends of the two connecting rods, and a load-bearing structure mounted on both sides of the quenching tank on the workbench.

[0004] As shown above, this device enables batch immersion quenching with high efficiency. The quenching fluid fully covers the regulating valve, improving the quenching effect and eliminating dead zones. It frees up manpower and increases work efficiency. However, multiple support frames are stacked together to form a nearly closed cylindrical structure. The quenching fluid is basically stagnant inside, and small-amplitude shaking has little effect on breaking the flow dead zone in this closed space, which can easily cause uneven cooling. Summary of the Invention

[0008] Preferably, the stirring mechanism includes a first belt connected to the drive assembly via a pulley drive, one end of the first belt being connected to a fixed shaft via a pulley drive, the outer wall of the fixed shaft being rotatably connected to the inner wall of the support frame, an electric telescopic rod being fixedly connected to the bottom of the fixed shaft, a locking block being fixedly connected to the bottom of the electric telescopic rod, and a rotating shaft being rotatably connected to the inner wall of the support frame.

[0009] Preferably, the rotating shaft has a slot adapted to the card block on the side near the card block, the outer wall of the rotating shaft is connected to a second belt via a pulley, the end of the second belt away from the rotating shaft is connected to a hollow rotating shaft via a pulley, the outer wall of the hollow rotating shaft is rotatably connected to the inner wall of the quenching tank, a number of baffles are fixedly connected to the top of the hollow rotating shaft, and a number of nozzles are fixedly connected to the top of the hollow rotating shaft.

[0010] Preferably, a first water pump is fixedly connected to the outer wall of the quenching pool, a bidirectional pipe is fixedly connected to the outer wall of the first water pump, the outer wall of the bidirectional pipe is fixedly connected to the inner wall of the quenching pool, a first pipe is fixedly connected to the output end of the first water pump, and the end of the first pipe away from the first water pump is rotatably connected to the inner wall of the hollow rotating shaft.

[0011] Preferably, the draining mechanism includes a draining shell fixedly connected to the outer wall of the quenching tank, a baffle slidably connected to the inner wall of the draining shell, a second pipe fixedly connected to the bottom of the draining shell, a second water pump fixedly connected to the bottom of the second pipe, a third pipe fixedly connected to the output end of the second water pump, a filter shell fixedly connected to the end of the third pipe away from the second water pump, the outer wall of the filter shell fixedly connected to the outer wall of the quenching tank, and a clamping plate snapped into the inner wall of the filter shell.

[0012] Preferably, a filter plate is fixedly connected to the inner wall of the filter housing, a guide block is fixedly connected to the inner wall of the filter housing, a push block is slidably connected to the inner wall of the guide block, the outer wall of the push block contacts the outer wall of the filter plate, a first collection housing is fixedly connected to the outer wall of the filter housing, a channel is fixedly connected to the bottom of the filter housing, and a second collection housing is fixedly connected to the bottom of the channel.

[0013] This invention also discloses a quenching method for a quenching device used in the production of regulating valves, specifically including the following steps: S1. By manually rotating the lead screw, the longitudinal position of each fixed block in the housing can be independently controlled, so that multiple fixed blocks can be arranged in a stepped high and low arrangement, thereby isolating each regulating valve workpiece from each other in space. S2. By rotating the worm gear, the worm wheel is driven to rotate, which in turn drives the bidirectional lead screw to rotate, so that the two clamps move synchronously towards each other along the inner side of the fixed block, thereby firmly clamping the regulating valve workpiece. Subsequently, the electric push rod in the drive assembly drives the fixed plate to descend as a whole, immersing the workpiece in the quenching medium of the quenching pool. S3. Under the command of the external controller, the drive component starts and drives the electric push rod and the workpiece on the fixed plate below it to rotate. At the same time, the rotational motion output by the electric push rod is transmitted to the fixed shaft through the first belt to realize power splitting.

[0014] The present invention has the following beneficial effects: 1. The quenching device and quenching process for the production of the regulating valve involves manually adjusting the screw to drive the fixed blocks to move within the housing, resulting in a stepped distribution of multiple fixed blocks. This allows for independent adjustment of the position of each regulating valve, ensuring their separation and preventing cooling dead spots caused by contact. A worm gear drives a worm wheel to rotate a bidirectional screw, causing two clamps to move towards each other and hold the regulating valve. Finally, an electric push rod below the drive assembly immerses the entire fixed plate into the quenching tank for cooling. This achieves intervalized and adjustable clamping of the regulating valve, effectively ensuring uniform quenching and cooling without dead spots.

[0015] 2. The quenching device and quenching process for the production of the regulating valve are activated by an external controller to drive the drive assembly, which in turn drives the electric push rod and the workpiece on the fixed plate to rotate. At the same time, the rotation of the electric push rod is transmitted to the fixed shaft through the first belt. After the electric telescopic rod pushes the locking block into the rotating shaft, the power is further transmitted through the second belt to drive the hollow rotating shaft to rotate, thereby driving the baffle plate and nozzle in the quenching tank to rotate synchronously. Meanwhile, the first water pump is started, drawing quenching liquid from both sides of the quenching tank through a bidirectional pipeline and pumping it into the hollow rotating shaft through the first pipeline. Finally, the rotating nozzle dynamically sprays the liquid toward the workpiece, which enhances the convection and heat exchange efficiency of the medium and ensures uniform cooling of complex contour surfaces.

[0016] 3. The quenching device and quenching process used in the production of this regulating valve: After quenching, the electric push rod and electric telescopic rod in the drive assembly retract, and the external drive source drives the drive assembly and the workpiece as a whole to move into the draining shell. After manually closing the baffle, the drive assembly drives the workpiece to rotate at high speed, centrifugally throwing off the residual quenching liquid on the surface, achieving rapid draining, which facilitates the timely transfer of the workpiece to the tempering process. At the same time, the quenching liquid accumulated in the draining shell is pumped into the filter shell by the second water pump through the second pipeline. The solid impurities carried in it are intercepted by the filter plate, while the clean quenching liquid penetrates the filter plate and flows into the second collection shell for recycling. The card plate is manually pushed periodically, so that the push block moves along the guide block, pushing the impurities intercepted by the filter plate into the first collection shell for centralized cleaning. This realizes the rapid dehydration of the workpiece after quenching and the online filtration and recycling of the quenching liquid. While improving the safety of tempering and the efficiency of process connection, it reduces media loss and keeps the oil clean.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention discloses a quenching device for manufacturing control valves and provides the following three technical solutions: Figures 1-3 The first embodiment is shown: it includes a quenching pool 1, a support frame 101 fixedly connected to the outer wall of the quenching pool 1, a fixing mechanism 2 provided on the top of the quenching pool 1, a stirring mechanism 3 provided on the outer wall of the quenching pool 1, and a draining mechanism 4 provided on the outer wall of the quenching pool 1. The fixing mechanism 2 includes a drive assembly 201 disposed on the outer wall of the support frame 101. The drive assembly 201 mainly consists of a servo motor and an integrated electric push rod. The drive assembly 201 is connected to several fixing plates 202 via the electric push rod. The fixing plates 202 are arranged in a circle and are detachably connected to the telescopic end of the electric push rod via quick-connect couplings, so that lifting and lowering actions can be performed synchronously. A housing 203 is fixedly connected to the outer wall of the fixing plate 202. A lead screw 204 is rotatably connected to the inner wall of the housing 203. A fixing block 205 is threadedly connected to the outer wall of the lead screw 204. The fixing block 205 cooperates with the lead screw 204 through its internal threaded hole and is connected to the straight rod 205 through the inner wall of the housing 203. The linear guide rail enables smooth displacement along the axial direction of the lead screw. A bidirectional lead screw 206 is rotatably connected to the inner wall of the fixed block 205. The bidirectional lead screw 206 is horizontally set inside the fixed block 205 and has two sections of threads with opposite directions of rotation. A worm gear 207 is fixedly connected to the outer wall of the bidirectional lead screw 206. A worm 208 is meshed on the outer wall of the worm gear 207. Two clamps 209 are threadedly connected to the outer wall of the bidirectional lead screw 206. The two clamps 209 respectively mesh with the two sections of reverse threads on the bidirectional lead screw 206, so that they can move synchronously in opposite directions or in opposite directions under the drive of the worm 208 to complete the clamping and release of the workpiece. The clamping surface of the clamp 209 is provided with a replaceable heat-resistant pad to adapt to different workpiece profiles.

[0023] The outer wall of the fixed block 205 is slidably connected to the inner wall of the housing 203, and the outer walls of the two clamps 209 are slidably connected to the inner wall of the fixed block 205. The drive assembly 201 includes a drive source and an electric push rod. The electric push rod is electrically connected to the external drive source. The drive source receives instructions from the external control system to control the extension stroke and speed of the electric push rod. The entire drive assembly 201 is mounted on the support frame 101 through a linear module, which can drive the fixed mechanism 2 to perform horizontal reciprocating motion between the quenching pool 1 and the draining mechanism 4.

[0024] Figures 4-6The second embodiment is shown, and its main difference from the first embodiment is that the stirring mechanism 3 includes a first belt 301 connected to the drive assembly 201 via a pulley. While the electric push rod of the drive assembly 201 is moving up and down, its rotation output shaft can drive the first belt 301 to rotate via the drive wheel. One end of the first belt 301 is connected to a fixed shaft 302 via a pulley. The fixed shaft 302 is installed vertically, and its top is connected to the first belt 301 via a driven wheel, thereby transmitting power to the shaft. The outer wall of the fixed shaft 302 is rotatably connected to the inner wall of the support frame 101. An electric telescopic rod 303 is fixedly connected to the bottom of the fixed shaft 302. The telescopic end of the electric telescopic rod 303 faces downwards to realize the subsequent locking function. A locking block 304 is fixedly connected to the bottom of the electric telescopic rod 303. A rotating shaft 305 is rotatably connected to the inner wall of the support frame 101. The rotating shaft 305 is installed directly below the fixed shaft 302, and the axes of the two are aligned.

[0025] The rotating shaft 305 has a slot on the side near the locking block 304 that matches the locking block 304. When the electric telescopic rod 303 extends downward, the locking block 304 can be inserted into the slot, thereby linking the fixed shaft 302 and the rotating shaft 305, allowing power to continue to be transmitted downward. A second belt 306 is connected to the outer wall of the rotating shaft 305 via a pulley drive. A drive pulley is installed on the rotating shaft 305, and the rotational motion is transmitted to the next stage via the second belt 306. The end of the second belt 306 away from the rotating shaft 305 is connected via a pulley drive. A hollow rotating shaft 307 is provided, which vertically penetrates the bottom of the quenching tank 1 and is connected to the tank body through a rotating seal. The outer wall of the hollow rotating shaft 307 is rotatably connected to the inner wall of the quenching tank 1. Several baffles 308 are fixedly connected to the top of the hollow rotating shaft 307. The baffles 308 are evenly installed around the top of the hollow rotating shaft 307 to drive the quenching liquid to form a directional vortex when rotating. Several nozzles 309 are fixedly connected to the top of the hollow rotating shaft 307. The nozzles 309 are evenly distributed among the baffles 308 to cover the workpiece area.

[0026] A first water pump 310 is fixedly connected to the outer wall of the quenching pool 1. The first water pump 310 is fixed to the outside of the quenching pool 1. The pump body needs to be adapted to possible splashing liquid and oil and gas environment. A bidirectional pipe 311 is fixedly connected to the outer wall of the first water pump 310. The two suction ports of the bidirectional pipe 311 extend to the bottom areas of the left and right sides of the quenching pool 1 respectively to draw quenching liquid evenly from different positions and prevent local overheating. The outer wall of the bidirectional pipe 311 is fixedly connected to the inner wall of the quenching pool 1. A first pipe 312 is fixedly connected to the output end of the first water pump 310. The end of the first pipe 312 away from the first water pump 310 is rotatably connected to the inner wall of the hollow rotating shaft 307. The connection adopts a high-speed rotary joint to ensure that the quenching liquid is sealed and transported between the stationary pipe and the rotating hollow rotating shaft 307. Finally, the liquid is sprayed out from the nozzle 309 at the top of the hollow rotating shaft 307 through the flow channel inside the hollow rotating shaft 307.

[0027] Figures 7-8 The third embodiment is shown, and its main difference from the first two embodiments is that the draining mechanism 4 includes a draining shell 401 fixedly connected to the outer wall of the quenching tank 1. The draining shell 401 is a box-shaped structure with a side opening, and its internal space is used to accommodate the quenched workpiece and perform the draining operation. A baffle 402 is slidably connected to the inner wall of the draining shell 401. The baffle 402 can be manually driven to close or open the top opening of the draining shell 401 to prevent liquid splashing and collect the splashed quenching liquid. A second pipe 403 is fixedly connected to the bottom of the draining shell 401. The drain port at the bottom is used to drain the accumulated quenching liquid. The bottom of the second pipe 403 is fixedly connected to the second water pump 404. The output end of the second water pump 404 is fixedly connected to the third pipe 405. The end of the third pipe 405 away from the second water pump 404 is fixedly connected to the filter housing 406. The second water pump 404 is used to pump the quenching liquid in the drain housing 401 to the inside of the filter housing 406. The outer wall of the filter housing 406 is fixedly connected to the outer wall of the quenching pool 1. The inner wall of the filter housing 406 is clamped with a clamping plate 407. The clamping plate 407 is detachably installed at the side wall opening of the filter housing 406 for easy maintenance of the internal filter components.

[0028] A filter plate 408 is fixedly connected to the inner wall of the filter housing 406. The filter plate 408 is horizontally installed inside the filter housing 406 and adopts a multi-layer metal filter structure to intercept solid impurities such as oxide scale and sludge in the quenching liquid. A guide block 409 is fixedly connected to the inner wall of the filter housing 406. A push block 410 is slidably connected to the inner wall of the guide block 409. The outer wall of the push block 410 contacts the outer wall of the filter plate 408. When the push block 410 moves along the guide block 409, it can scrape off the impurities attached to the surface of the filter plate 408 and push them to one side. A first collection housing 411 is fixedly connected to the outer wall of the filter housing 406. A channel 412 is fixedly connected to the bottom of the filter housing 406. The channel 412 is located below the filter plate 408 and is used to collect the clean quenching liquid passing through the filter plate 408 and discharge it. A second collection housing 413 is fixedly connected to the bottom of the channel 412.

[0029] This invention also discloses a quenching method for a quenching device used in the production of regulating valves, specifically including the following steps: First, the heated fixing plate 202 is connected to the drive assembly 201. In order to adjust the position of each regulating valve so that they do not contact each other and prevent the existence of cooling dead points, the lead screw 204 is manually rotated to move the fixing block 205 in the housing 203. The positions of several fixing blocks 205 are adjusted at one time to make them into a stepped shape to prevent the regulating valves from touching each other. The worm gear 208 is manually rotated to make the worm wheel 207 rotate, which in turn makes the bidirectional lead screw 206 rotate, thereby driving the two clamps 209 to come closer and clamp the regulating valve. Then, the electric push rod under the drive assembly 201 is activated to lower the several fixing plates 202 connected to it into the quenching tank 1 for cooling.

[0030] After the lowering is completed, the drive assembly 201 is started by the external controller. The electric push rod rotates, causing several fixed plates 202 below to rotate. At the same time, the electric push rod rotates, causing the first belt 301 to rotate, which in turn causes the fixed shaft 302 to rotate. Before the fixed shaft 302 rotates, the electric telescopic rod 303 is started by the external controller, causing the locking block 304 to move down, so that the locking block 304 is locked into the rotating shaft 305. At this time, the fixed shaft 302 rotates, causing the second belt 306 to rotate, which in turn causes the hollow rotating shaft 307 to rotate, thereby causing the baffle plate 308 and nozzle 309 in the quenching tank 1 to rotate together. Then, the first water pump 310 is started by the external controller, which draws the quenching liquid from both sides of the quenching tank 1 through the bidirectional pipe 311 and delivers it to the interior of the hollow rotating shaft 307 through the first pipe 312, and then sprays it towards the workpiece through the nozzle 309.

[0031] After quenching is completed, the electric push rod and electric telescopic rod 303 in the drive assembly 201 retract, and then the external drive source drives the entire drive assembly 201 to move, thereby moving the workpiece below the drive assembly 201 together. When it moves into the drain housing 401, the baffle 402 is manually closed, and then the drive assembly 201 is started again. The electric push rod drives the workpiece below to rotate, and the residual coolant is spun dry. Then the workpiece is quickly removed and tempered. At this time, the quenching liquid remaining in the drain housing 401 is drawn by the second water pump 404 through the second pipe 403 and input into the filter housing 406. The impurities on the workpiece are intercepted by the filter plate 408, and the remaining quenching liquid enters the second collection housing 413 through the filter plate 408 and the channel 412. Then the latch plate 407 is manually opened, and the push block 410 moves in the guide block 409, thereby pushing the impurities intercepted by the filter plate 408 into the first collection housing 411 to complete the collection.

A channel (412) is fixedly connected to the bottom of the filter housing (406). A second collection housing (413) is fixedly connected to the bottom of the channel (412).

8. A quenching method for a quenching apparatus for manufacturing control valves according to claim 3, characterized in that, Specifically, the following steps are included: S1. By manually rotating the lead screw (204), the longitudinal position of each fixed block (205) in the housing (203) can be independently controlled, so that multiple fixed blocks (205) can form a stepped high and low arrangement, thereby isolating each regulating valve workpiece in space. S2. By rotating the worm (208) to drive the worm wheel (207) to rotate, the bidirectional lead screw (206) is driven to rotate, so that the two clamps (209) move synchronously towards each other along the inner side of the fixed block (205), thereby firmly clamping the regulating valve workpiece. Subsequently, the electric push rod in the drive assembly (201) drives the fixed plate (202) to descend as a whole, immersing the workpiece in the quenching medium of the quenching pool (1). S3. Under the command of the external controller, the drive assembly (201) is started, driving the electric push rod and the workpiece on the fixed plate (202) below it to rotate. At the same time, the rotational motion output by the electric push rod is transmitted to the fixed shaft (302) through the first belt (301) to realize power diversion.
