The device boasts a high degree of automation, eliminating the need for workers to repeatedly come into close contact with the high-temperature processing area, thus reducing the accident rate during production. In the multi-station ring rolling structure, the active roller, the first auxiliary roller, and the second auxiliary roller perform ring rolling processing on the billet from different directions.

[0033] 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.

[0034] Please see Figures 1-10 This invention provides a technical solution: a multi-station rolling mill device with a main roller structure for wind turbine flange production, comprising,

[0035] A processing table 1 is connected to a lifting plate 2 via a lifting component. The blank 3 is placed on the lifting plate 2. The lifting plate 2 is moved up and down by the extension and retraction of the lifting component, thereby adjusting the height position of the blank 3 to meet the processing requirements of different processes.

[0036] The multi-station unit includes a forging assembly for forging the billet 3 and a main rolling ring assembly linked to the forging assembly. The forging assembly includes a fixed block 4 connected by a multi-directional motion assembly and a forging head 5 movably located at the lower end of the fixed block 4. The upper end of the forging head 5 is provided with a polygonal path motion mechanism, which is used to drive the forging head 5 to move in a quadrilateral path. The polygonal path motion mechanism is located inside the fixed block 4. By driving the forging head 5 to move in a quadrilateral path through the polygonal path motion mechanism, the billet 3 can be forged at multiple angles and positions, thereby improving the forging effect. The main rolling ring assembly includes an active roller 6, a moving mechanism for driving the active roller 6 to move, and a positioning mechanism for positioning the forged billet 3. The active roller 6, the moving mechanism, and the positioning mechanism are all located on the processing table 1.

[0037] And an auxiliary rolling ring unit, which includes a first auxiliary roller 7, a second auxiliary roller 8 and a drive mechanism. Both the first auxiliary roller 7 and the second auxiliary roller 8 are driven to move by the drive mechanism.

[0038] In use, the blank 3 is placed on the lifting plate 2, and the second cylinder 17 in the second drive component is activated to extend and retract. Then, the fixed block 4 and the forging head 5 are driven to forge the blank 3 downward through the connecting column 9. At the same time, the first motor 19 in the polygonal path motion mechanism is activated. The first motor 19 starts to drive the eccentric block 20 to rotate, and pushes the moving frame 21 to reciprocate along a square path. Then, the forging head 5 moves along a quadrilateral path to perform forging processing on the blank 3 at multiple positions.

[0039] After forging, the diameter of the billet 3 is larger than the diameter of the lifting plate 2. Then, the forging head 5 is reset to be directly above the lifting plate 2. The positioning mechanism is activated, and the fourth cylinder 29 drives the positioning plate 28 to move, positioning the billet 3. At this time, the lifting component is activated to move the lifting plate 2 downward. Then, the punching die is placed on the billet 3 for punching. The second cylinder 17 is activated again to extend and retract, continuously hammering the punching die. Under the hammering action of the forging head 5, the lower end of the punching die moves into the processing table 1, thereby completing the punching of the center position of the billet 3. Then, the punching die is moved away, and the second cylinder 17 is activated again to extend and move the forging head 5 to the inner diameter of the center of the billet 3. Then, the first cylinder 15 is activated to extend, and the fixed block 4 is moved towards the active roller 6 through the connecting block 10 and the connecting column 9. The moving mechanism is activated, and the third cylinder 24 drives the first slide plate 26 to move, so that the active roller 6 moves towards the billet 3 until it touches the side of the billet 3. At this time, the third motor 27 and the second motor are activated, and the active roller 6 and the forging head 5 begin to rotate to roll the billet 3.

[0040] Simultaneously, according to processing requirements, the auxiliary ring rolling unit is activated. The fifth cylinder 33 in the first auxiliary component drives the second slide plate 31 to move, bringing the first auxiliary roller 7 closer to the billet 3. The seventh cylinder 32 adjusts the distance between the two first auxiliary rollers 7, and the fourth motor drives the first auxiliary roller 7 to rotate to perform auxiliary ring rolling on the upper and lower ends of the billet 3. The sixth cylinder 34 in the second auxiliary component drives the third slide plate 35 to move, bringing the second auxiliary roller 8 closer to the billet 3. The fifth motor 36 drives the second auxiliary roller 8 to rotate to further perform auxiliary ring rolling on the side of the billet 3. Through the device of the present invention, the forging, punching and ring rolling processes are integrated on the same processing table 1, reducing the number of times the high-temperature billet 3 is handled, improving production efficiency, and reducing safety hazards. At the same time, through the positioning mechanism and the multi-station ring rolling structure, the positioning error during process transition is reduced, and the processing accuracy of the wind turbine flange is improved.

[0041] The forging head 5 is located directly above the lifting plate 2. The multi-directional motion assembly includes a connecting column 9 fixedly installed on the upper end of the fixed block 4, a connecting block 10 fixedly connected to the upper end of the connecting column 9, a first driving component that drives the connecting block 10 to move back and forth, and a second driving component that drives the connecting column 9 to move up and down. Through the cooperation of the first driving component and the second driving component, the fixed block 4 can move back and forth and up and down, thereby driving the forging head 5 to move in multiple directions. Fixed plates 11 are slidably connected to both sides of the connecting block 10, and the fixed plates 11 are fixedly installed... Mounted on the frame 12, a T-shaped plate 13 is slidably connected to the upper end of the fixed plate 11. The first driving component is installed on the fixed plate 11, and the second driving component is installed on the T-shaped plate 13. As the connecting column 9 and the connecting block 10 move, the T-shaped plate 13 slides synchronously on the upper end of the fixed plate 11 under the connection of the second driving component. The lifting component is an electric telescopic column 14, which is installed inside the processing table 1. The upper end of the electric telescopic column 14 is fixedly connected to the lifting plate 2, and the lifting plate 2 is movably embedded in the middle of the top side of the processing table 1.

[0042] There are two first driving components, which are symmetrically distributed to ensure that the connecting block 10 is subjected to uniform force and moves more smoothly. The first driving component includes a first cylinder 15 and a first mounting block 16. Both first mounting blocks 16 are L-shaped and are fixedly connected to adjacent fixed plates 11. The two first cylinders 15 are respectively mounted on adjacent first mounting blocks 16. The output shafts of the two first cylinders 15 are fixedly connected to the connecting block 10. When the first cylinder 15 works, its output shaft extends and retracts, causing the connecting block 10 to slide at the lower end of the first mounting block 16, thereby realizing the forward and backward movement of the connecting block 10.

[0043] The second driving component includes a second cylinder 17 and a second mounting block 18. The second mounting block 18 is fixedly connected to the outer wall of the connecting column 9. The second mounting block 18 includes a fixing ring and two symmetrically distributed extension plates. The fixing ring and the two extension plates are integrally formed. The lower end of the T-shaped plate 13 is fixedly connected to two symmetrically distributed second cylinders 17. The output shafts at the lower ends of the two second cylinders 17 are fixedly connected to the two extension plates. When the second cylinder 17 is working, its output shaft extends and retracts, driving the second mounting block 18 to move up and down, thereby driving the connecting column 9 and the fixing block 4 to move up and down. The lower ends of the T-shaped plate 13 that contact the fixing plate 11 on both sides are provided with T-shaped grooves 40. The upper ends of the fixing plate 11 on both sides are fixedly connected with T-shaped sliders 41 that slide in the T-shaped grooves 40. The T-shaped grooves 40 and T-shaped sliders 41 can limit the sliding direction of the T-shaped plate 13.

[0044] The polygonal path motion mechanism includes a first motor 19, an eccentric block 20, a moving frame 21, and a fifth mounting block 22, all installed within a fixed block 4. The first motor 19 is mounted on the upper inner wall of the fixed block 4. The output shaft of the first motor 19 is fixedly connected to the eccentric block 20, which is located within the moving frame 21. When the first motor 19 drives the eccentric block 20 to rotate, the eccentric block 20 pushes the moving frame 21 to perform repetitive motion along a square path. Two symmetrically distributed reinforcing columns 23 are fixedly connected to the upper end of the moving frame 21. Two symmetrically distributed limiting grooves 39 are formed on the upper wall of the fixed block 4. The limiting grooves 39 are square, and the reinforcing columns 23 are T-shaped. The upper ends of the reinforcing columns 23 slide within the limiting grooves 39. As the eccentric block 20 rotates... The upper end of the reinforcing column 23 fixed on the moving frame 21 slides in the limiting groove 39. The limiting groove 39 limits the movement of the reinforcing column 23, thereby limiting the movement of the moving frame 21 and preventing the moving frame 21 from rotating with the eccentric block 20. The setting of the reinforcing column 23 plays a limiting and stabilizing role in the movement of the moving frame 21. The lower end of the moving frame 21 is fixedly connected to the fifth mounting block 22. The lower end of the fifth mounting block 22 is rotatably connected to the forging head 5. The fifth mounting block 22 is installed in the second motor. The lower output shaft of the second motor is fixedly connected to the upper end of the forging head 5. The setting of the second motor facilitates the subsequent ring rolling work of the billet 3, allowing the forging head 5 to directly cooperate with the active roller 6 to perform ring rolling, without the need to set up a separate roller shaft for ring rolling the inner wall of the billet 3.

[0045] The moving mechanism includes a third cylinder 24, a first groove 25, and a first slide plate 26. The processing table 1 has a first groove 25, and the first slide plate 26 is slidably connected in the first groove 25. One end of the first slide plate 26 is fixedly connected to the output shaft of the third cylinder 24. When the third cylinder 24 is working, the output shaft extends and retracts, causing the first slide plate 26 to slide in the first groove 25. The active roller 6 is rotatably located at the end of the first slide plate 26 away from the third cylinder 24. The lower end of the active roller 6 is fixedly connected to the output shaft of the third motor 27. The third motor 27 is installed on the first slide plate 26. The third motor 27 drives the active roller 6 to rotate, realizing the ring rolling action. The positioning mechanism includes several positioning plates 28 slidably located on the upper end of the processing table 1 and a fourth cylinder 29. One end of each of the positioning plates 28 is connected to the output shaft of the fourth cylinder 29. The fourth cylinder 29 drives the positioning plates 28 to move, positioning the blank 3, increasing the positioning effect of the blank 3 during punching and ring rolling, and thus preventing the punching and ring rolling from being impossible due to positional errors.

[0046] Both the first auxiliary roller 7 and the second auxiliary roller 8 are movably mounted on the processing table 1. There are two of each type of auxiliary roller 7 and the second auxiliary roller 8. The two first auxiliary rollers 7 are symmetrically distributed vertically. The driving mechanism includes a first auxiliary component that drives the first auxiliary roller 7 to move and a second auxiliary component that drives the second auxiliary roller 8 to move.

[0047] The first auxiliary component includes a third mounting block 30, a second sliding plate 31, a seventh cylinder 32, and a fifth cylinder 33. One end of each of the two first auxiliary rollers 7 is fixedly connected to a fourth motor. Both fourth motors are installed inside the third mounting block 30. The two third mounting blocks 30 are mounted on the second sliding plate 31. The seventh cylinder 32 is mounted on the upper end of the second sliding plate 31. The lower output end of the seventh cylinder 32 is fixedly connected to one of the third mounting blocks 30. The seventh cylinder 32 can drive one of the third mounting blocks 30 to move up and down, adjusting the distance between the two first auxiliary rollers 7. One side of the second sliding plate 31 is fixedly connected to the output end of the fifth cylinder 33. The fifth cylinder 33 drives the second sliding plate 31 to move, thereby moving the first auxiliary rollers 7 as a whole.

[0048] The second auxiliary component includes a sixth cylinder 34 and a third slide plate 35. Two second auxiliary rollers 8 are rotatably mounted on one end of the third slide plate 35. The lower end of the second auxiliary rollers 8 is fixedly connected to the output shaft of the fifth motor 36. The fifth motor 36 is mounted on the third slide plate 35. The end of the third slide plate 35 away from the second auxiliary rollers 8 is fixedly connected to the output shaft of the sixth cylinder 34. The sixth cylinder 34 drives the third slide plate 35 to move, thereby moving the second auxiliary rollers 8.

[0049] The processing table 1 is provided with several second grooves 37. The second slide plate 31 and the third slide plate 35 are respectively slidably disposed in the corresponding second grooves 37. The second grooves 37 provide guidance for the sliding of the second slide plate 31 and the third slide plate 35. One end of the third cylinder 24, the fourth cylinder 29, the fifth cylinder 33 and the sixth cylinder 34 are all mounted on the fourth mounting block 38. Multiple fourth mounting blocks 38 are mounted on the side of the processing table 1.
