Description

Technical Field

[0001] This invention relates to the field of wind turbine flange processing technology, and in particular to a wind turbine flange forging processing device and processing method. Background Technology

[0002] Wind turbine flanges are disc-shaped structural components used to connect and fix key parts in wind turbine generator sets. Their main function is to firmly combine the tower sections, tower and nacelle, hub and blades, etc., with high-strength bolts, while transmitting huge loads and ensuring sealing and fatigue resistance. A ring rolling mill is required during forging.

[0003] Application number CN202610708600.6 discloses a wind turbine flange forging processing device, including a ring rolling mill body composed of a frame, a top frame, auxiliary rollers, a drive roller, and an axial roller. A fixed shaft seat is connected to the end of the top frame via a flange. A mandrel is rotatably mounted on the bottom end of the fixed shaft seat. The bottom end of the mandrel is provided with a sliding base that can be horizontally adjusted. This invention uses a detection shaft fixed to the sliding base and multiple sets of sliding rods distributed along the axial direction to monitor the thermal expansion state of the mandrel during rotation in real time, automatically adjusting the flow rate and temperature of the cooling water to maintain the overall temperature of the mandrel within a suitable range. Furthermore, when the circumferential thermal expansion of the mandrel is uneven, the adjusting components can locally heat up or cool down the mandrel, effectively avoiding bending caused by uneven thermal deformation, reducing thermal fatigue damage, and extending its service life.

[0004] Based on the above patent search and understanding of the application of existing wind power flange forging equipment: The existing ring rolling equipment can only complete the flange ring rolling process. After the ring is rolled, it needs to be transferred to an independent milling machine for milling. The secondary transfer and positioning of the workpiece has a coaxiality deviation, which can easily cause the flange processing dimensions to exceed the tolerance. In addition, the two processes are carried out separately, resulting in low overall processing efficiency. The existing flange rolling ring positioning support structure cannot adaptively adjust the clamping support according to wind power flanges of different diameters. Large-size flange rolling rings are prone to radial displacement and swaying during rotation, resulting in poor rolling ring forming accuracy. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a wind turbine flange forging processing device and method. This addresses the issues of existing ring rolling processing equipment requiring secondary transfer of workpieces during process separation, which can easily lead to coaxiality deviations and dimensional errors, resulting in low production efficiency. Furthermore, the supporting positioning support structure cannot be adapted to the self-adjusting support of wind turbine flanges of various diameters, and large-specification flanges are prone to radial displacement and swaying during ring rolling.

[0006] This invention provides a forging processing device and method for wind turbine flanges, specifically including: a device frame; an adapter frame fixedly installed on the top of the device frame, an additional mounting frame fixedly installed inside the front of the adapter frame, a power motor shaft provided at the rear top of the additional mounting frame, a progressive frame fixedly installed at the front top of the additional mounting frame, a third motor fixedly installed above the front of the progressive frame, the shaft of the third motor being threaded and located inside the upper part of the progressive frame, an extension slide being slidably connected to the front top of the upper part of the interior of the progressive frame, a threaded hole for threaded engagement with the shaft of the third motor being opened at the front top of the extension slide, and a semi-circular... At the center of the gear frame, a surrounding frame slides on the outer side of the semi-circular gear frame. The surrounding frame is equipped with a fourth motor, and the shaft of the fourth motor is fixed with a gear that meshes with the semi-circular gear frame. A advancing cylinder is located at the bottom of the surrounding frame. A milling cutter is mounted on the sliding rod at the front end of the advancing cylinder via a chuck. A cooling water tank is fixed at the top front of the mounting frame. A water pump is installed inside the cooling water tank, and the output end of the water pump is connected to a pump pipe nozzle. The pump pipe nozzle is fixed at the position of the sliding rod of the advancing cylinder and moves back and forth synchronously with the milling cutter. A flange body is sleeved on the outer side of the power motor shaft. The power motor shaft is located behind the advancing cylinder, and the flange body is placed on the top of the adapter frame and located between the two arc-shaped frames.

[0007] Furthermore, a hydraulic cylinder is fixedly installed at the middle of the rear end of the device frame, and the front end of the telescopic rod of the hydraulic cylinder is fixed to the ring rolling machine frame, which slides in the rear area inside the adapter frame.

[0008] Furthermore, a lower conical roller body is provided inside the ring rolling mill frame at the lower part, and the top of the lower conical roller body is flush with the top of the mounting frame. An upper conical roller body slides inside the ring rolling mill frame at the upper part. The lower conical roller body and the upper conical roller body are symmetrically designed and are both driven by motors. A threaded hole is opened at the top of the upper conical roller body. A first motor is fixed at the top of the ring rolling mill frame. The first motor shaft is opened with a threaded hole, and the thread of the first motor shaft is threaded to fit the threaded hole of the upper conical roller body.

[0009] Furthermore, a second motor is provided at the bottom front of the adapter frame, the second motor shaft is threaded, a sliding seat is slidably connected to the bottom front of the adapter frame, a threaded hole is provided in the middle of the sliding seat, and the threaded shaft of the second motor is threaded into the threaded hole of the sliding seat.

[0010] Furthermore, a transmission plate is rotatably connected to each side of the rear end of the sliding seat, and a transmission foot is rotatably connected to the other end of each transmission plate. The two transmission feet are respectively rotated to the front position on both sides of the adapter frame.

[0011] Furthermore, the top of each of the transfer feet is fixed to the front end of the arc-shaped frame, and the two arc-shaped frames are symmetrically distributed on both sides of the front of the top of the adapter frame.

[0012] Furthermore, a main wheel rotates at the rear of the arc-shaped frame, and the upper rear end of the arc-shaped frame is rotatably connected to the lower middle of the auxiliary frame. The auxiliary frame is coaxial with the main wheel, and auxiliary wheels rotate on both sides of the auxiliary frame. The outermost distance of the auxiliary wheel is flush with the outermost distance of the main wheel.

[0013] A processing method for a wind turbine flange forging processing device includes the following steps: 1) Place the flange blank on the outside of the power motor shaft at the top of the mounting frame. The flange blank falls to the top of the adapter frame and is located in the middle of the two arc-shaped frames. Start the second motor at the bottom front of the adapter frame. The second motor shaft rotates and drives the sliding seat to slide forward along the bottom of the adapter frame. When the sliding seat moves forward, it pulls the two transmission plates to swing forward synchronously. The transmission plates push and pull the transmission feet at both ends to rotate inward around the hinge point of the adapter frame. The two transmission feet synchronously drive the arc-shaped frame fixed at the top to close towards each other until the main wheel at the rear end of the arc-shaped frame and the auxiliary wheel on the auxiliary frame are in contact with the outer ring of the flange blank. This completes the adaptive clamping and limiting of flanges of different diameters. Turn off the second motor. Through the cooperation of the main wheel and the auxiliary wheel on the auxiliary frame, the flange blank is given multiple limiting effects. This avoids the traditional single limiting wheel on both sides being easily affected by external forces and causing displacement, which affects the flange forming structure. 2) During the ring rolling forming process, start the hydraulic cylinder at the middle position of the rear end of the device frame. The hydraulic cylinder extension rod extends forward, pushing the ring rolling frame to slide forward along the rear area inside the adapter frame, so that the lower conical roller body inside the ring rolling frame is in contact with the lower part of the flange blank. Start the first motor at the top of the ring rolling frame. The first motor shaft rotates, driving the upper conical roller body to slide downward along the inside of the ring rolling frame. Adjust the roller gap between the upper and lower conical roller bodies to match the thickness of the flange blank. Start the matching drive motors of the lower and upper conical roller bodies respectively. The upper and lower conical rollers of the upper and lower conical roller bodies rotate synchronously to squeeze the flange blank. At the same time, start the matching motor of the power motor shaft to drive the flange body to rotate slowly, continuously rolling and expanding the diameter until the outer diameter and thickness of the flange body reach the forging standard dimensions, thus completing the ring rolling forming. 3) After the ring rolling is completed, start the third motor at the front and top of the advancing frame. The screw of the third motor rotates and drives the extension slide to slide backward along the inside of the advancing frame. The extension slide drives the bottom semi-circular tooth frame, the surrounding frame, the advancing cylinder, and the milling cutter to move backward synchronously until the axis of the semi-circular tooth frame is directly above the axis of the forming flange body. At the same time, the milling cutter is moved to the flange body milling area. Start the advance cylinder at the bottom of the surround frame. The sliding rod at the front end of the advance cylinder extends forward, pushing the chuck-mounted milling cutter to adhere to the flange surface for milling. When the upper and lower tapered roller bodies drive the flange body to rotate in conjunction with the power motor shaft, the milling cutter completes the milling process on the outside of the flange body. Simultaneously, the water pump inside the cooling water tank at the front of the top of the mounting frame is turned on. The water pump delivers cooling water to the pump pipe nozzle. The pump pipe nozzle moves synchronously with the sliding rod of the advance cylinder, continuously spraying cooling water onto the cutting contact surface between the milling cutter and the flange body to cool down and remove chips.

[0014] On the other hand, the fourth motor on the surround frame is started. The shaft of the fourth motor drives the gear to rotate continuously. The gear meshes with the semi-circular gear frame and drives the surround frame to slide along the outer circumference of the semi-circular gear frame, so that the milling cutter has the ability to move around the flange body. The position of the milling cutter and the pump pipe nozzle can be flexibly adjusted to achieve fine adjustment of the cutting position. 4) After the milling process is completed, the drive motors and power motor shafts of the upper and lower cone roller bodies are turned off. The first motor is started in reverse to drive the upper cone roller body to rise and reset. The hydraulic cylinder is started in reverse to pull the ring rolling frame backward and retract the whole body from the flange body. The second motor is started in reverse, and the sliding seat slides backward. Through the transmission plate and transmission foot, the two arc-shaped frames on both sides are driven to open outward, releasing the outer ring support limit of the flange body. At the same time, the third motor drives the extension slide to move forward, and the semi-circular toothed frame and all auxiliary components are removed from the space above the flange body, making it convenient for the finished flange body to be unloaded and taken out.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By integrating the rolling ring mechanism and the surrounding milling mechanism into one unit, the rolling ring can be directly milled after it is formed without the need to transfer the workpiece, eliminating the need for secondary clamping and positioning steps, ensuring the coaxial machining accuracy of the flange, and thus solving the problems of dimensional deviation and low process separation efficiency caused by workpiece transfer and clamping deviation. 2. An adaptive support structure that drives the double-sided arc frame to open and close synchronously through the linkage of the second motor, sliding seat, transmission plate, and transmission foot can match the clamping and limiting of flange bodies of different diameter specifications. During the ring rolling process, the main wheel and auxiliary wheel are in contact with the outer ring of the flange for stable support, thereby solving the problems of rotational swaying and radial displacement of large-size flange ring rolling and poor forming accuracy. 3. Through the cooling structure of the cooling water tank that moves synchronously with the advance cylinder and the pump nozzle that moves synchronously with the milling cutter, the cooling water continuously sprays on the contact surface between the milling cutter and the flange during the milling operation, which removes the high temperature of milling in real time, reduces the wear of the milling cutter, and thus solves the problems of fast tool wear and burr formation on the workpiece surface in high temperature flange milling. 4. A multi-degree-of-freedom milling adjustment structure is used, in which the extension carriage is fed forward and backward by a third motor, and the semi-circular gear is driven by a fourth motor to rotate the surrounding frame in a circular motion. The milling cutter can continuously mill around the flange body at multiple angles, avoiding positional limitations. Attached Figure Description

The pump pipe nozzle 312 is fixed at the sliding rod position of the progressive cylinder 309 and moves back and forth synchronously with the milling cutter 310. A flange body 4 is sleeved on the outside of the power motor shaft 301. The power motor shaft 301 is located behind the progressive cylinder 309. The flange body 4 is placed on the top of the adapter frame 2 and is located between two arc-shaped frames 205. The two arc-shaped frames 205 are symmetrically arranged and fit together with the outer circumferential surface of the flange body 4 to form a multi-point support limit.

[0021] Hydraulic cylinder 101 is fixedly installed at the middle of the rear end of device frame 1. The front end of the telescopic rod of hydraulic cylinder 101 is fixed to ring rolling machine frame 102. Ring rolling machine frame 102 slides in the rear area inside adapter frame 2. The telescopic rod of hydraulic cylinder 101 is rigidly connected to ring rolling machine frame 102, driving ring rolling machine frame 102 to move back and forth along the guide rail of adapter frame 2.

[0022] The ring rolling mill frame 102 has a lower conical roller body 103 located at the bottom inside. The top of the conical roller body 103 is flush with the top of the mounting frame 3. An upper conical roller body 104 slides inside the upper part of the ring rolling mill frame 102. The lower conical roller body 103 and the upper conical roller body 104 are symmetrically designed and both are driven by motors. They jointly extrude the flange blank of the flange body 4 to complete the ring rolling and diameter expansion forming. A threaded hole is opened on the top of the upper conical roller body 104. A first motor 105 is fixed on the top of the ring rolling mill frame 102. The shaft of the first motor 105 is threaded, and the thread of the shaft of the first motor 105 is threaded and matches the threaded hole of the upper conical roller body 104.

[0023] The adapter 2 has a second motor 201 at the bottom front, the shaft of the second motor 201 is threaded, and a sliding seat 202 is slidably connected to the bottom front of the adapter 2. A threaded hole is opened in the middle of the sliding seat 202. The shaft of the second motor 201 is threaded to the threaded hole of the sliding seat 202, driving the sliding seat 202 to slide back and forth along the bottom of the adapter 2.

[0024] The sliding seat 202 has a transmission plate 203 rotatably connected to each of its two rear ends. The other end of the transmission plate 203 is rotatably connected to a transmission foot 204. The two transmission feet 204 are rotatably positioned at the front center of both sides of the adapter frame 2. The top of each transmission foot 204 is fixed to the front end of the arc frame 205. The two arc frames 205 are symmetrically distributed on the front center of the top of the adapter frame 2. A main wheel 206 rotatably rotates behind the arc frame 205. The upper rear end of the arc frame 205 is rotatably connected to the lower center of the auxiliary frame 207. The auxiliary frame 207 is coaxial with the main wheel 206, and auxiliary wheels 208 rotatably rotate on both sides of the auxiliary frame 207. The outermost distance of the auxiliary wheel 208 is flush with the outermost distance of the main wheel 206. The main wheel 206 and the auxiliary wheel 208 are coaxially engaged and jointly adhere to the outer ring of the flange body 4 to form multi-point rolling support, reducing rotational friction and limiting the radial displacement of the workpiece.

[0025] In use: Place the flange body 4 blank on the outside of the power motor shaft 301 at the top of the mounting frame 3. The flange body 4 blank falls to the top of the adapter frame 2 and is positioned between the two arc-shaped frames 205. Start the second motor 201 at the bottom front of the adapter frame 2. The shaft of the second motor 201 rotates, driving the sliding seat 202 to slide forward along the bottom of the adapter frame 2. When the sliding seat 202 moves forward, it pulls the two transmission plates 203 to swing forward synchronously. The transmission plates 203 push and pull the transmission feet 204 at both ends to rotate inward around the hinge point of the adapter frame 2. The foot 204 synchronously drives the top fixed arc frame 205 to close towards each other until the main wheel 206 at the rear end of the arc frame 205 and the auxiliary wheel 208 on the auxiliary frame 207 are in contact with the outer ring of the flange body 4 blank, completing the adaptive clamping and limiting of flange bodies 4 with different diameters. The second motor 201 is turned off. Through the cooperation of the main wheel 206 and the auxiliary wheel 208 on the auxiliary frame 207, the flange body 4 blank is given multiple limiting effects, avoiding the displacement caused by the traditional single limiting wheel set on both sides, which is easily affected by external forces and affects the forming structure of the flange body 4.

[0026] During the ring rolling forming process, the hydraulic cylinder 101 at the middle of the rear end of the starter frame 1 is activated. The telescopic rod of the hydraulic cylinder 101 extends forward, pushing the ring rolling frame 102 to slide forward along the rear area inside the adapter frame 2, so that the lower conical roller body 103 inside the ring rolling frame 102 is attached to the bottom of the flange body 4 blank. The first motor 105 at the top of the ring rolling frame 102 is activated. The first motor 105 rotates its shaft thread, driving the upper conical roller body 104 to slide downward along the inside of the ring rolling frame 102, adjusting the roller gap between the upper conical roller body 104 and the lower conical roller body 103 to match the flange body 4 flange blank thickness. The matching drive motors of the lower conical roller body 103 and the upper conical roller body 104 are activated respectively. The upper and lower conical rollers of the upper conical roller body 104 and the lower conical roller body 103 rotate synchronously to squeeze the flange body 4 flange blank. At the same time, the matching motor of the power motor shaft 301 is activated to drive the flange body 4 to rotate slowly, continuously rolling and expanding the diameter until the outer diameter and thickness of the flange body 4 reach the forging standard dimensions, thus completing the ring rolling forming.

[0027] After the ring rolling is completed, the third motor 303 above the front of the advance frame 302 is started. The shaft of the third motor 303 rotates, driving the extension slide 304 to slide backward along the inside of the advance frame 302. The extension slide 304 drives the bottom semi-circular tooth frame 305, the surrounding frame 306, the advance cylinder 309, and the milling cutter 310 to move backward synchronously until the axis of the semi-circular tooth frame 305 is above the axis of the forming flange body 4. At the same time, the milling cutter 310 is moved to the milling area of ​​the flange body 4. The advance cylinder 309 at the bottom of the surround frame 306 is activated. The sliding rod at the front end of the advance cylinder 309 extends forward, pushing the chuck-mounted milling cutter 310 to adhere to the surface of the flange body 4 for milling. When the upper tapered roller body 104 and the lower tapered roller body 103 drive the motor and the power motor shaft 301 to rotate the flange body 4, the milling cutter 310 completes the milling process on the outside of the flange body 4. At the same time, the water pump inside the cooling water tank 311 at the top front of the mounting frame 3 is turned on. The water pump delivers cooling water to the pump pipe nozzle 312. The pump pipe nozzle 312 moves synchronously with the sliding rod of the advance cylinder 309, continuously spraying cooling water onto the cutting contact surface between the milling cutter 310 and the flange body 4 to cool down and remove chips.

[0028] On the other hand, the fourth motor 307 on the surround frame 306 is started. The shaft of the fourth motor 307 drives the gear 308 to rotate continuously. The gear 308 meshes with the semi-circular gear frame 305 and drives the surround frame 306 to slide along the outer circumference of the semi-circular gear frame 305, so that the milling cutter 310 has the ability to move around the flange body 4 in a circle, changing the current position of the milling cutter 310 and the pump pipe nozzle 312, and achieving the effect of structural fine adjustment.

[0029] After the ring rolling is completed, the drive motor and power motor shaft 301 of the upper conical roller body 104 and the lower conical roller body 103 are closed. The first motor 105 is started in reverse to drive the upper conical roller body 104 to rise. The hydraulic cylinder 101 is started in reverse to pull the ring rolling frame 102 to reset backward and separate from the flange body 4.

[0030] The second motor 201 is started in reverse, and the sliding seat 202 slides backward. Through the transmission plate 203 and the transmission foot 204, the arc-shaped frames 205 on both sides are driven to open outward, releasing the outer ring support limit of the flange body 4. At the same time, the third motor 303 drives the extension slide 304 to move forward, and the semi-circular toothed frame 305 and its auxiliary parts are removed from the top of the flange body 4, making it easier for the flange body 4 to be unloaded.

The outermost distance of the auxiliary wheel (208) is flush with the outermost distance of the main wheel (206).

8. The processing method of the wind turbine flange forging processing device as described in any one of claims 1-7, characterized in that, Includes the following steps: 1) Place the flange body (4) blank on the outside of the power motor shaft (301) at the top of the mounting frame (3). The flange body (4) blank falls to the top of the adapter frame (2) and is in the middle of the two arc-shaped frames (205). Start the second motor (201) at the bottom front of the adapter frame (2). The shaft of the second motor (201) rotates, driving the sliding seat (202) to slide forward along the bottom of the adapter frame (2). When the sliding seat (202) moves forward, it pulls the two transmission plates (203) to swing forward synchronously. The transmission plates (203) push and pull the transmission feet (204) at both ends to rotate inward around the hinge point of the adapter frame (2). The transmission foot (204) synchronously drives the top fixed arc frame (205) to close towards each other until the main wheel (206) at the rear end of the arc frame (205) and the auxiliary wheel (208) on the auxiliary frame (207) are in contact with the outer ring of the flange body (4) blank, thus completing the adaptive clamping limit of flange bodies (4) of different diameters. The second motor (201) is turned off. Through the cooperation of the main wheel (206) and the auxiliary wheel (208) on the auxiliary frame (207), the flange body (4) blank is given multiple limit effects, avoiding the traditional single limit wheel on both sides being easily affected by external forces and causing displacement, affecting the forming structure of the flange body (4); 2) During the ring rolling forming process, start the hydraulic cylinder (101) at the middle of the rear end of the device frame (1). The telescopic rod of the hydraulic cylinder (101) extends forward, pushing the ring rolling frame (102) to slide forward along the rear area inside the adapter frame (2), so that the lower conical roller body (103) inside the ring rolling frame (102) fits against the flange body (4) below the blank. Start the first motor (105) at the top of the ring rolling frame (102). The first motor (105) rotates the screw of the shaft, driving the upper conical roller body (104) to slide downward along the inside of the ring rolling frame (102). Adjust the roll gap between the upper conical roller body (104) and the lower conical roller body (103) to match the flange blank thickness of the flange body (4); start the matching drive motors of the lower conical roller body (103) and the upper conical roller body (104) respectively, and the upper and lower conical rollers of the upper conical roller body (104) and the lower conical roller body (103) rotate synchronously to squeeze the flange blank of the flange body (4). At the same time, start the matching motor of the power motor shaft (301) to drive the flange body (4) to rotate slowly, and continue to roll the ring to expand the diameter until the outer diameter and thickness of the flange body (4) reach the forging standard size, and complete the ring rolling forming; 3) After the ring rolling is completed, start the third motor (303) above the front of the advance frame (302). The shaft of the third motor (303) rotates and drives the extension slide (304) to slide backward along the inside of the advance frame (302). The extension slide (304) drives the bottom semi-circular tooth frame (305), the surrounding frame (306), the advance cylinder (309), and the milling cutter (310) to move backward synchronously until the axis of the semi-circular tooth frame (305) is located directly above the axis of the forming flange body (4). At the same time, the milling cutter (310) is moved to the milling processing area of ​​the flange body (4). Start the advance cylinder (309) at the bottom of the surround frame (306). The sliding rod at the front end of the advance cylinder (309) extends forward and pushes the chuck-mounted milling cutter (310) to the flange body (4) for milling. When the upper cone roller body (104) and the lower cone roller body (103) drive the flange body (4) to rotate in cooperation with the power motor shaft (301), the milling cutter (310) completes the milling process on the outside of the flange body (4). At the same time, the water pump inside the cooling water tank (311) at the top front of the mounting frame (3) is turned on. The water pump delivers cooling water to the pump pipe nozzle (312). The pump pipe nozzle (312) moves synchronously with the sliding rod of the advance cylinder (309) and continuously sprays cooling water onto the cutting contact surface of the milling cutter (310) and the flange body (4) to cool down and remove chips. On the other hand, the fourth motor (307) on the surround frame (306) is started. The shaft of the fourth motor (307) drives the gear (308) to rotate continuously. The gear (308) meshes with the semi-circular gear frame (305) and drives the surround frame (306) to slide along the outer circumference of the semi-circular gear frame (305), so that the milling cutter (310) has the ability to move around the flange body (4) in a circular motion. The position of the milling cutter (310) and the pump pipe nozzle (312) can be flexibly adjusted to achieve fine adjustment of the cutting position. 4) After the milling process is completed, the drive motors of the upper conical roller body (104) and the lower conical roller body (103) and the power motor shaft (301) are turned off. The first motor (105) is started in reverse to drive the upper conical roller body (104) to rise and reset. The hydraulic cylinder (101) is started in reverse to pull the ring rolling frame (102) to retract backward and separate the whole from the flange body (4). The second motor (201) is started in reverse, and the sliding seat (202) slides backward. Through the transmission plate (203) and the transmission foot (204), the two arc-shaped frames (205) are driven to open outward, releasing the outer ring support limit of the flange body (4). At the same time, the extension slide (304) is driven to move forward through the third motor (303), and the semi-circular toothed frame (305) and all auxiliary components are removed from the space above the flange body (4) to facilitate the unloading and removal of the processed flange body (4).
