Description

Technical Field

[0001] The present invention relates to the technical field of gear ring rolling forging, and particularly relates to a wind power planetary gear ring rolling forging device and a forging method thereof. Background Art

[0002] Ring rolling is a metal forming process in which a metal material heated to the recrystallization temperature is gradually thinned and extended into a ring by applying pressure with a roller. In the field of wind power generation, planetary gears, as key components in the transmission system, have extremely high requirements for the accuracy and strength of their ring-shaped components such as planet gears and internal gear rings. Compared with traditional casting or forging processes, the ring rolling process, with its advantages of high precision and strength, has become an ideal choice for manufacturing the ring-shaped components of wind power planetary gears.

[0003] However, during the ring rolling process, iron oxide is extremely likely to be generated in the high-temperature metal material. Even if someone holds a water gun by hand to flush and clean the outer wall of the ring-shaped part, a small amount of iron oxide that cannot be avoided due to dead corners and other problems cannot be removed. And with the extension of working time, the accumulation of this iron oxide will not only damage the mold, but also affect the surface quality of the ring-shaped part. More importantly, the accumulation of iron oxide will cause the ring-shaped part to vibrate during the ring rolling process, and this vibration will destroy the stability of the ring rolling process, ultimately resulting in damage to the ring rolling accuracy and affecting the product quality. Summary of the Invention

[0004] Aiming at the above-mentioned disadvantages of the prior art, the present invention provides a wind power planetary gear ring rolling forging device and a forging method thereof, which can effectively solve the problems in the prior art that the iron oxide that cannot be removed accumulates with the extension of working time, not only affecting the surface quality of the ring-shaped part, but also causing the ring-shaped part to vibrate during the ring rolling process, and then resulting in damage to the ring rolling accuracy of the ring-shaped part.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: The present invention provides a wind power planetary gear ring rolling forging device, including: A mounting seat body; A driving part, the driving part includes a supporting bracket arranged on the mounting seat body and connected to an external lifting device, a core roller fixedly connected to the output shaft of an external motor is installed on the supporting bracket, and an arc-shaped scraping plate for scraping the outer wall of the core roller is fixedly connected to the lower end surface of the supporting bracket; A guiding part, the guiding part includes a rectangular mounting block slidably arranged on the mounting seat body through an electric slide rail, an installation groove is opened inside the rectangular mounting block and an adjusting component is installed inside its installation groove. The installation groove is divided into two installation areas I and one installation area II. The two installation areas I are respectively arranged on both sides of the installation area II and are symmetrically arranged according to the installation area II; Among them, the adjusting component includes a guiding frame with guiding rollers respectively arranged at both ends. An actuator is installed on the upper end surface of the front side of the guiding frame, and a pressing member is installed above the actuator. Among them, the actuator includes an arc-shaped mounting plate arranged on the guiding frame through a second torsion spring. Scraping knives are respectively and fixedly arranged on the inner and outer side walls of the arc-shaped mounting plate. The pressing member includes a U-shaped frame and a triangular inclined platform fixedly arranged on the inner wall of the U-shaped frame with an inclined through groove opened on the end surface. A sliding block is slidably arranged inside the through groove.

[0006] Furthermore, the guiding frame is rotatably arranged inside two installation areas I through a first torsion spring, and the scraping knife on the inner wall of the arc-shaped mounting plate on the guiding frame always fits against the outer wall of the guiding roller. The scraping knife on the outer side of the arc-shaped mounting plate always fits against the outer wall of the annular member under the adjustment of the guiding frame and the arc-shaped mounting plate.

[0007] Furthermore, the U-shaped frame is fixedly arranged on the upper end surface of the guiding frame. The sliding block adopts a separable structure and is divided into a pressing block and a connecting block connected to the pressing block through a first tension spring. Among them, the lower end surface of the pressing block is in contact with the upper surface of the annular member, and a linkage plate penetrating through the through groove is fixedly connected to the side of the pressing block away from the annular member. The connecting block is slidably arranged inside the through groove through a second spring and a L-shaped plate is fixedly arranged at the end away from the annular member. High-pressure nozzles connected to an external water inlet device are respectively and fixedly arranged on both sides of the U-shaped frame.

[0008] Furthermore, hinge plates with their upper ends hinged to the linkage plate are arranged on both side walls of the triangular inclined platform. The central positions of the hinge plates are rotatably connected to the triangular inclined platform, and oval slots are respectively opened at the ends of the two hinge plates away from each other. Ratchets I are respectively and rotatably connected to the positions of the triangular inclined platform corresponding to the lower ends of the two hinge plates. Shaft rods are slidably arranged inside the oval slots of the two hinge plates, and the other ends of the shaft rods are rotatably connected to the eccentric positions of the ratchets I. Below the ratchets I and on the U-shaped frame, a pawl I cooperating with the ratchets I is rotatably connected through a mounting disc. A matching plate is commonly connected between the two mounting discs, and the two mounting discs are respectively connected to the U-shaped frame through third torsion springs.

[0009] Furthermore, a strip-shaped groove is opened inside the rectangular mounting block and below the two guiding frames. An adjusting member is installed inside the strip-shaped groove. The adjusting member includes two threaded rods rotatably arranged on the inner wall of the strip-shaped groove and symmetrically arranged in the left-right direction. The two threaded rods are commonly connected to a double-shaft motor that controls their intermittent rotation. C-shaped pushing blocks are respectively and threadedly connected to the outer walls of the two threaded rods inside the strip-shaped groove, and the two C-shaped pushing blocks are respectively in contact with the outer walls of the corresponding guiding frames.

[0010] Furthermore, two circular grooves symmetrically arranged in the left - right direction and extending downward are formed inside the rectangular mounting block. A limiting member is arranged inside the circular groove. The limiting member includes an adjusting column rotatably installed inside the circular groove and having a plurality of arc - shaped grooves formed along the circumferential direction on its outer wall. The top end of the adjusting column is fixedly connected with an arc - shaped clamping block through a disc. A pawl two that cooperates with the arc - shaped groove of the adjusting column is also rotatably connected inside the circular groove through a gear. The limiting member further includes a rack that slidably penetrates through the rectangular mounting block and the pawl two and is always meshed with the gear for transmission. The meshing of the rack and the gear locks to prevent the pawl two from rotating when it is located inside the arc - shaped groove.

[0011] Furthermore, the adjusting assembly further includes a cooperating member arranged inside the installation area two and used to cooperate with the two guide frames to complete the guiding work of the annular member. The cooperating member includes a square block slidably arranged inside the installation area two through a second tension spring and having rectangular grooves formed on both side walls. Inside each of the two rectangular grooves, a clamping block group with a mating groove formed on its end face is slidably connected. Each clamping block group includes a plurality of rectangular clamping blocks connected by a rotating shaft and respectively connected to the inner wall of the rectangular groove through a third spring. On the side where the two rectangular clamping blocks are away from each other, connecting rods are respectively connected through extrusion rollers. The two connecting rods are connected to the rectangular mounting block through a fourth spring and are slidably arranged inside the rectangular mounting block.

[0012] Furthermore, a rotating roller that fits the outer wall of the annular member is rotatably connected to one side of the square block close to the guide roller, and a plurality of zigzag grooves that cooperate with the arc - shaped clamping blocks are formed along the length direction on the upper surface of the square block.

[0013] A forging method of a wind - power generation planetary gear ring - rolling forging device includes the following steps: S1: Placement of the annular member. First, heat the annular member to an appropriate temperature, and then use an external feeding device to place the annular member on the mounting seat body. The bearing bracket is driven downward by an external lifting device. During this process, the core roller and the arc - shaped scraper gradually enter the inside of the annular member, and the lower end face of the core roller fits with the mounting seat body. S2: Limiting in the radial direction of the annular member. The rectangular mounting block gradually approaches the annular member driven by the electric slider. The guide rollers on both sides first fit with the outer wall of the annular member to complete the preliminary limiting work of the annular member. At the same time, the rotating roller on the square block inside the installation area two also fits with the outer wall of the annular member under the movement of the rectangular mounting block. S3: Limit the annular part in the axial direction. Control the push rod arranged above the rectangular mounting block to extend, and drive the L-shaped plate to slide downward along the through groove during the movement. The pressing block also slides downward along the through groove under the action of the connecting block and the first tension spring. During the sliding process, the end face of the pressing block fits with the upper surface of the annular part. With the continuous extension of the telescopic section of the push rod, the connecting block continues to move downward and continuously stretches the first tension spring. Since the pressing block fits with the annular part, it cannot continue to move. The axial direction limit of the annular part is realized by the synchronous downward movement of the left and right pressing blocks; S4: Ring rolling operation of the annular part. Start the driving motor to drive the core roll and the driving roll to rotate in opposite directions synchronously. During the rotation process, control the driving roll to gradually move towards the core roll and make the outer wall of the driving roll fit with the outer wall of the annular part. During the ring rolling process, the arc-shaped scraping plate and the slag scraping knife are used to scrape the residual iron oxide on the outer walls of the core roll and the guiding roll respectively. As the driving roll continuously squeezes the annular part towards the core roll, continuous local plastic deformation of the outer wall of the annular part is gradually realized. During this process, control the two tapered rolls to rotate synchronously, and during the rotation process, the upper tapered roll is driven by the electric slider to gradually move downward and closely adhere to the upper surface of the annular part. As the annular part is pressed downward on the upper surface, the height of the annular part is changed; S5: Repeat S1 - S4 to perform the ring rolling operation on the next annular part.

[0014] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: In the present invention, during the deformation process of the annular part, the high-pressure nozzles on both sides of the C-shaped frame are started, and the high-pressure water column ejected by the high-pressure nozzles is used to complete the cooling work during the ring rolling of the annular part. At the same time, part of the iron oxide generated on the outer wall of the annular part is washed and cleaned by the high-pressure water column. As the annular part rotates reciprocally, the slag scraping knife arranged on the outer wall of the arc-shaped mounting plate is used to scrape the residual iron oxide on the outer wall of the annular part, and cooperate with the high-pressure water column to complete the scraping and cleaning work of the iron oxide on the outer wall of the annular part, thereby improving the processing quality of the outer wall of the annular part during the ring rolling operation, and further avoiding the problem of vibration of the annular part during the ring rolling operation due to the residual iron oxide.

[0022] The U-shaped frame 3251 is fixedly arranged on the upper end surface of the guiding frame 321. The sliding block adopts a separable structure and is divided into a pressing block 3253 and a connecting block 3254 connected to the pressing block 3253 through a first tension spring. Among them, the lower end surface of the pressing block 3253 fits against the upper surface of the annular member, and a linkage plate 3255 penetrating through the through groove is fixedly connected to the side of the pressing block 3253 away from the annular member.

High-pressure nozzles connected to external water inlet devices are respectively and fixedly arranged on both sides of the U-shaped frame 3251.

[0023] Hinged plates 32521 with the upper ends hinged to the linkage plate 3255 are arranged on both side walls of the triangular inclined platform 3252. The central position of the hinged plate 32521 is rotatably connected to the triangular inclined platform 3252, and oval slots are opened at the ends of the two hinged plates 32521 away from each other.

A shaft rod is slidably arranged inside the oval slots of the two hinged plates 32521, and the other end of the shaft rod is rotatably connected to the eccentric position of the ratchet I 32522.

[0024] Inside the rectangular mounting block 31 and below the two guide frames 321, a strip-shaped groove 311 is provided. An adjusting member 322 is installed inside the strip-shaped groove 311. The adjusting member 322 includes two threaded rods 3221 that are rotatably arranged on the inner wall of the strip-shaped groove 311 and are symmetrically arranged in the left-right direction. The two threaded rods 3221 are jointly connected to a double-shaft motor that controls their intermittent rotation.

[0025] Inside the rectangular mounting block 31, two circular grooves that are symmetrically arranged in the left-right direction and extend downward are provided. A limiting member 312 is arranged inside the circular grooves. The limiting member 312 includes an adjusting column 3121 that is rotatably installed inside the circular groove and has a plurality of arc-shaped grooves provided on its outer wall along the circumferential direction. The top end of the adjusting column 3121 is fixedly connected with an arc-shaped clamping block 3122 through a disc. Inside the circular groove, a ratchet pawl two 3124 that is rotatably connected through a gear 3123 and is matched with the arc-shaped groove of the adjusting column 3121 is also provided. The limiting member 312 further includes a rack 3125 that slidably penetrates through the rectangular mounting block 31 and the ratchet pawl two 3124 and is always in meshing transmission with the gear 3123. Through the meshing and locking of the rack 3125 and the gear 3123, the ratchet pawl two 3124 is prevented from rotating back when it is located inside the arc-shaped groove.

[0026] The adjusting assembly 32 further includes a fitting member 326 that is arranged inside the installation area two and is used to cooperate with the two guide frames 321 to complete the guiding work of the annular member. The fitting member 326 includes a square block 3261 that is slidably arranged inside the installation area two through a second tension spring and has rectangular grooves provided on both side walls. Inside each of the two rectangular grooves, a block group with a fitting groove provided on the end face is slidably connected. Each block group includes a plurality of rectangular clamping blocks 3262 that are connected through a rotating shaft and are respectively connected to the inner wall of the rectangular groove through a third spring. On the sides of the two rectangular clamping blocks 3262 away from each other, connecting rods 3264 are respectively connected through pressing rollers 3263. The two connecting rods 3264 are connected to the rectangular mounting block 31 through a fourth spring and are slidably arranged inside the rectangular mounting block 31.

[0027] On one side of the square block 3261 close to the guide roller 323, a roller 32611 that is in contact with the outer wall of the annular member is rotatably connected. And on the upper surface of the square block 3261, a plurality of zigzag grooves 32612 that are matched with the arc-shaped clamping blocks 3122 are provided along its length direction.

[0028] During actual work, the placement work of the annular member before ring rolling: First, the ring is heated to an appropriate temperature, and then an external loading device is used to place the ring on the mounting seat body 1 (in the initial state, after the ring is placed, a certain distance must be left between it and the driving roller, in order to facilitate the subsequent adjustment of the position of the ring), and then the external lifting device drives the support frame 21 to move downward. During this process, the core roller 22 and the arc scraper 23 gradually enter the interior of the ring and make the lower end surface of the core roller 22 fit with the mounting seat body 1, so as to avoid a gap between the mounting seat body 1 and the core roller 22 during the ring rolling process, thereby causing the core roller 22 to shake.

[0029] While the core roller 22 is driven downward by the support frame 21, the rectangular mounting block 31 on the other side of the ring part is gradually approached to the ring part under the drive of the electric slider (in the initial state, one end of the guide frame 321 is located on the outside of the rectangular mounting block 31. Therefore, during the movement of the rectangular mounting block 31, the guide rollers 323 on both sides preferentially fit with the outer wall of the ring part to complete the preliminary limiting work of the ring part. At the same time, the rotating roller 32611 on the inner square block 3261 of the second installation area also fits with the outer wall of the ring part under the movement of the rectangular mounting block 31). The ring part is accurately centered on the mounting seat body 1 through the guide frames 321 on both sides and the middle square block 3261. The three-point centering mechanism is used to effectively eliminate the initial offset of the ring part that may occur during the clamping process, thereby ensuring that its geometric center coincides with the rotation center of the core roller 22, avoiding problems such as uneven rolling force and inconsistent plastic deformation of materials caused by coaxiality errors, thereby ensuring the dimensional accuracy and roundness of the ring part after ring rolling.

[0030] When the annular member completes the preliminary positioning work, the rectangular mounting block 31 also moves to the specified position, and then the push rod (not shown in the drawings of the specification) arranged above the rectangular mounting block 31 is controlled to extend. During the extension process, the telescopic section of the push rod first contacts the L-shaped plate 3256 arranged on the two connecting blocks 3254, and drives the L-shaped plate 3256 to slide downward along the inclined through groove during the movement process (in the initial state, the pressure block 3253 and the connecting block 3254 are close to each other under the action of the tension spring 1, and the pressure block 3253 gradually slides downward along the through groove under the action of the connecting block 3254 and the tension spring 1, and its end face is in contact with the upper surface of the annular member during the sliding process, the telescopic section of the push rod continues to extend, the connecting block 3254 continues to move downward and continuously stretches the tension spring 1, and the pressure block 3253 cannot continue to move due to its contact with the annular member), the axial direction of the annular member is limited by the synchronous downward movement of the left and right pressure blocks 3253, thereby preventing the annular member from jumping in the axial direction due to pressure during the later ring rolling work.

[0031] As the telescopic section of the push rod continues to extend, it drives the L-shaped plate 3256 to push down the mating plate 32524, causing the two mounting discs on the same guide frame 321 to rotate around their centers. During the rotation of the two mounting discs, the pawl one 32523 fixedly arranged thereon also rotates and fits with the ratchet one 32522, thereby restricting the ratchet one 32522 from reversing. (In the initial state of the linkage plate 3255, the part protruding from the triangular inclined platform 3252 is less. As the pressing block 3253 is pulled downward by the connecting block 3254 and the first tension spring, the length of the linkage plate 3255 outside the triangular inclined platform 3252 gradually increases. During this process, the hinge plate 32521 arranged thereon synchronously changes its position and drives the ratchet one 32522 below to rotate. The pawl one 32523 arranged on the C-shaped frame 3251 can effectively restrict the ratchet one 32522 from moving upward and rebounding under the reverse force of the annular part. Through the ratchet and pawl mechanism, the stability of the pressing block 3253 pressing down on the upper surface of the annular part can be further ensured).

[0032] It should be noted that when the ring rolling work of the annular part has not been carried out initially, the arc-shaped clamping blocks 3122 on both sides are respectively located inside the serrated grooves 32612 of the corresponding square blocks 3261. In the initial state of the square block 3261, the second tension spring arranged thereon is in a stretched state. The arranged arc-shaped clamping blocks 3122 can effectively prevent the square block 3261 from retracting under the force of the second tension spring, improving the stability of the three-point positioning work on the outer wall of the annular part.

[0033] Ring rolling work of the annular part: After completing the positioning work of the annular part, first start the driving motor to drive the core roller 22 and the driving roller (not shown in the specification drawings) to rotate in opposite directions synchronously. During the rotation, control the driving roller to gradually move towards the core roller 22 and make the outer wall of the driving roller fit with the outer wall of the annular part. (When the inner and outer walls of the annular part are respectively in contact with the core roller 22 and the driving roller, the annular part will rotate synchronously under the drive of the two rollers rotating in opposite directions. One side of the core roller 22 is in contact with the annular part, and the other side is in contact with the arc-shaped scraping plate 23. When the core roller 22 is rotating, the arc-shaped scraping plate 23 always scrapes the residual iron oxide on its outer wall to ensure the smooth operation of the core roller 22 during the working process and avoid the annular part from shifting due to excessive residual iron oxide). As the driving roller continuously presses the annular part, continuous local plastic deformation of the outer wall of the annular part is realized. At the same time, when the annular part is deforming, start the high-pressure nozzles (not shown in the specification drawings) on both sides of the C-shaped frame 3251, and complete the cooling work during the ring rolling of the annular part by spraying high-pressure water columns from the high-pressure nozzles. At the same time, the high-pressure water columns wash and clean part of the iron oxide generated on the outer wall of the annular part to prevent the problem that the size of the outer wall of the annular part deviates due to excessive residual iron oxide.

[0034] During the process of the inner and outer diameters of the annular part gradually increasing, since the two guide frames 321 on both sides are rotationally installed inside the rectangular mounting block 31 through the first torsion spring, when the outer diameter of the annular part is gradually increasing, under the action of the first torsion spring, the two guide rollers 323 on both sides still fit against the outer wall of the annular part. At this time, as the annular part reciprocally rotates, the slag scraping knife 3242 provided on the outer wall of the arc-shaped mounting plate 3241 is used to scrape the residual iron oxide on the outer wall of the annular part, and in cooperation with the high-pressure water column, the iron oxide on the outer wall of the annular part is scraped and cleaned, thereby improving the processing quality of the outer wall of the annular part during the ring rolling operation, and at the same time further avoiding the problem that the vibration caused by the residual iron oxide during the ring rolling operation of the annular part leads to size deviation.

[0035] In order to prevent the annular part from shifting in the radial direction under force during the ring rolling process, at this time, a double-shaft motor (not shown in the attached drawings of the specification) is started to synchronously drive the two threaded rods 3221 on both sides to rotate intermittently. During the rotation of the two threaded rods 3221, the U-shaped push blocks 3222 on their respective outer walls are gradually driven to approach synchronously. During the synchronous approach of the two U-shaped push blocks 3222, they always fit against the outer wall of the guide frame 321, thereby reducing the elastic force of the first torsion spring provided on the guide frame 321. And during the synchronous approach of the two guide rollers 323 located inside the rectangular mounting block 31 on both sides, they respectively push against their corresponding connecting rods 3264 and extrusion rollers 3263. The two extrusion rollers 3263 on both sides respectively push the rectangular clamping blocks 3262 corresponding to them. When the front-end blocked rectangular clamping block 3262 is squeezed by the extrusion roller 3263, the rectangular clamping block 3262 will squeeze the third spring connected to it and slide into the rectangular groove. Subsequently, since the front-end rectangular clamping block 3262 completely enters the rectangular groove, at this time, the force blocking the reset of the square block 3261 disappears, so that the second tension spring quickly resets and drives the square block 3261 to slide along the installation area two. (The arc-shaped clamping block 3122 is initially located inside the serrated groove 32612. When the square block 3261 retracts, due to the cooperation of the second pawl 3124 and the arc-shaped groove on the adjusting column 3121, the square block 3261 will not be blocked during the retraction process. If the square block 3261 slides in the opposite direction under force after the retraction is completed, through the cooperation of the second pawl 3124 and the adjusting column 3121, and the gear 3123 and the rack 3125, the square block 3261 will be blocked and unable to move), through the gradual retraction of the square block 3261 and the synchronous separation of the guide rollers 323 located outside the rectangular mounting block 31 on both sides, it adapts to the gradual change of the diameter of the annular part, ensuring the continuous close contact between the guide roller 323 and the rotating roller 32611 and the outer wall of the annular part, thereby further ensuring the quality of the ring rolling processing.

[0036] At the same time, while the guide rollers 323 on both sides of the outer wall of the ring-shaped part are in close contact with the outer wall of the ring-shaped part, due to the friction force, the ring-shaped part will also drive the guide rollers 323 on both sides to rotate during the rotation process. During the rotation process of the guide rollers 323, the slag scraping knives 3242 arranged on the inner walls of the arc-shaped mounting plates 3241 complete the scraping and cleaning work on the outer walls of the guide rollers 323, avoiding the problem of scratching the ring-shaped part caused by a small amount of iron oxide adhering to the outer walls of the guide rollers 323 during long-term operation.

[0037] Meanwhile, control the synchronous rotation of two conical rollers (not shown in the attached drawings of the specification) and drive the upper conical roller to gradually move downward and be in close contact with the upper surface of the ring-shaped part during the rotation process. As the upper surface of the ring-shaped part is pressed downward, the height of the ring-shaped part is changed (as the height of the ring-shaped part gradually decreases, the pressing block 3253 slides downward along the through groove rapidly under the tension of the first tension spring due to the disappearance of the supporting force below, and always remains in close contact with the upper surface of the ring-shaped part, avoiding the axial vibration of the ring-shaped part during the ring rolling process. When the pressing block 3253 gradually moves downward with the decrease in the height of the ring-shaped part, the length of the linkage plate 3255 protruding from the triangular inclined platform 3252 also gradually increases. At this time, the hinge plate 32521 continues to change its angle and rotates around its central position. During this process, the hinge plate 32521 drives the ratchet wheel 32522 to rotate through the shaft rod arranged at the eccentric position of the first ratchet wheel 32522. Since the shaft rod is slidably arranged inside the elliptical groove, when the hinge plate 32521 rotates, the shaft rod can slide inside it through the opened elliptical groove to compensate for the position change between the shaft rod and the first ratchet wheel 32522. During the ring rolling work of the ring-shaped part, due to the existence of the height of the ring-shaped part itself, the linkage plate 3255 will not protrude too far from the triangular inclined platform 3252, thus also avoiding the phenomenon of jamming caused by a large rotation of the hinge plate 32521). Through the cooperation of the first pawl 32523 and the first ratchet wheel 32522, the linkage plate 3255 will not be blocked by the first pawl 32523 when moving downward and driving the hinge plate 32521 and the first ratchet wheel 32522 to rotate. Through the limit of the height of the ring-shaped part in two different directions, the axial vibration of the ring-shaped part during the ring rolling work is effectively avoided, thus ensuring the stable progress of the ring rolling work of the ring-shaped part and improving the dimensional accuracy and processing quality of the ring-shaped part after ring rolling.

[0038] When the ring part completes the ring rolling work, the telescopic section of the push rod above the conical roller and the rectangular mounting block 31 is controlled to move and retract synchronously. Since the force above the matching plate 32524 and the L-shaped plate 3256 disappears, the mounting plate drives the pawl 32523 to disengage from the ratchet wheel 32522. At the same time, the connecting block 3254 is quickly reset by the rebound force of the second spring and releases the pressure on the upper surface of the ring part. Then the rectangular mounting block 31 and the supporting bracket 21 are controlled to move away from the ring part. Finally, the ring part that has completed the ring rolling is transferred and transported by external conveying equipment.

[0039] It is worth emphasizing that the wind power planetary gear ring rolling forging equipment has the following advantages: Advantage 1: During the deformation of the ring part, the high-pressure nozzles on both sides of the forming frame 3251 are started, and the high-pressure water column sprayed from the high-pressure nozzle is used to cool the ring part during ring rolling. At the same time, the high-pressure water column flushes and cleans part of the iron oxide produced on the outer wall of the ring part. As the ring part reciprocates, the scraper 3242 arranged on the outer wall of the arc-shaped mounting plate 3241 is used to scrape off the iron oxide remaining on the outer wall of the ring part, and the high-pressure water column is used to scrape and clean the iron oxide on the outer wall of the ring part, thereby improving the processing quality of the outer wall of the ring part during the ring rolling work, and further avoiding the problem of dimensional deviation of the ring part after the ring rolling work due to the residual iron oxide.

[0040] Advantage two: The precise centering of the ring on the mounting seat body 1 is achieved through the guide frames 321 on both sides and the middle square block 3261. The three-point centering mechanism is adopted to effectively eliminate the initial offset of the ring during the clamping process, thereby ensuring that its geometric center coincides with the rotation center of the core roller 22, avoiding problems such as uneven rolling force and inconsistent plastic deformation of materials caused by coaxiality errors, thereby ensuring the dimensional accuracy and roundness of the ring after ring rolling.

[0041] Advantage three, the pressure block 3253 gradually slides downward along the slide groove under the action of the connecting block 3254 and the tension spring 1, and its end face fits with the upper surface of the ring during the sliding process, the telescopic section of the push rod continues to extend, the connecting block 3254 continues to move downward and continuously stretches the tension spring 1, and the pressure block 3253 cannot continue to move due to the fit with the ring. The axial direction of the ring is limited by the synchronous downward movement of the left and right pressure blocks 3253, thereby avoiding the axial jump of the ring due to pressure in the later ring rolling work.

[0042] Fourth, when the inner and outer walls of the annular part are respectively in contact with the core roller 22 and the driving roller, the annular part rotates synchronously under the drive of the two rollers rotating in opposite directions. One side of the core roller 22 is in contact with the annular part, and the other side is in contact with the arc-shaped scraper 23. When the core roller 22 rotates, the arc-shaped scraper 23 always scrapes the iron oxide remaining on its outer wall, ensuring the smooth operation of the core roller 22 during work and preventing the annular part from shifting due to excessive iron oxide residue.

[0043] Please refer to Figure 1 , on the other hand, the present invention provides a forging method for a wind power planetary gear ring rolling forging device, including the following steps: S1: Placement of the annular part. First, heat the annular part to an appropriate temperature, and then use an external feeding device to place the annular part on the mounting seat body 1. Drive the support bracket 21 to move downward by an external lifting device. During this process, the core roller 22 and the arc-shaped scraper 23 gradually enter the interior of the annular part and make the lower end surface of the core roller 22 in contact with the mounting seat body 1; S2: Limiting the annular part in the radial direction. The rectangular mounting block 31 gradually approaches the annular part under the drive of the electric slider. The guiding rollers 323 on both sides are preferentially in contact with the outer wall of the annular part to complete the preliminary limiting work of the annular part. At the same time, the rotating roller 32611 on the square block 3261 in the second installation area also comes into contact with the outer wall of the annular part under the movement of the rectangular mounting block 31; S3: Limiting the annular part in the axial direction. Control the push rod arranged above the rectangular mounting block 31 to extend and drive the L-shaped plate 3256 to slide downward along the through groove during the movement. The pressing block 3253 also slides downward along the through groove under the action of the connecting block 3254 and the first tension spring, and its end surface comes into contact with the upper surface of the annular part during the sliding process. When the telescopic section of the push rod continues to extend, the connecting block 3254 continues to move downward and continuously stretches the first tension spring. The pressing block 3253 cannot continue to move due to its contact with the annular part. The limiting work of the annular part in the axial direction is realized by the synchronous downward movement of the two pressing blocks 3253 on the left and right; S4: Ring rolling work of the annular part. Start the driving motor to drive the core roller 22 and the driving roller to rotate synchronously in opposite directions. During the rotation, control the driving roller to gradually move towards the core roller 22 and make the outer wall of the driving roller in contact with the outer wall of the annular part. During the ring rolling process, the arc-shaped scraper 23 and the slag scraping knife 3242 respectively scrape the iron oxide remaining on the outer walls of the core roller 22 and the guiding roller 323. As the driving roller continuously squeezes the annular part towards the core roller 22, continuous local plastic deformation of the outer wall of the annular part is gradually realized. During this process, control the two tapered rollers to rotate synchronously and drive the upper tapered roller to gradually move downward and closely contact the upper surface of the annular part by the electric slider during the rotation. As the upper surface of the annular part is pressed downward, the height of the annular part is changed; S5: Repeat S1 to S4 to perform the ring rolling operation on the next ring-shaped part.

During this process, the core roller (22) and the arc-shaped scraper (23) gradually enter the interior of the annular component and make the lower end surface of the core roller (22) fit the mounting seat body (1); S2: The annular member is limited in the radial direction.
