Description

Technical Field

[0001] The invention relates to the technical field of wind turbine shaft forging processing, in particular to a wind turbine shaft continuous forging device. Background Art

[0002] Wind turbine shaft forging is an important link in the manufacturing of wind power equipment, mainly involving the manufacturing process of the wind turbine main shaft. The wind turbine shaft, especially the wind turbine main shaft, is a key component in the wind turbine generator set, and undertakes the important functions of transmission and load-bearing. Its quality directly affects the overall performance and operating stability of the wind turbine generator set. Wind turbine shafts are generally made of low-alloy structural steel. This material has good strength, toughness and fatigue performance. During the forging process, the material undergoes plastic deformation and the internal structure is optimized, thereby further improving the mechanical properties of the shaft.

[0003] For example, the patent number disclosed in the China Patent Network is: CN 115533005 B, and the patent name is: A single-tooth radial forging molding device and process for a large-size spline shaft, including a molding table and a forging die device installed above the molding table, both sides of the top of the molding table are slid with sliding recesses, and the inner walls of the two sliding recesses are rotated with rotating drums, and the left sliding recess is provided with a pushing mechanism for intermittently driving the rotating drum, and an adjustment component for changing the distance between the two rotating drums is provided between the two sliding recesses. The present invention relates to the field of spline shaft processing technology. The single-tooth radial forging molding device and process for a large-size spline shaft, through the setting of the pushing mechanism, is convenient for equidistant intermittent flipping of the spline shaft, thereby realizing efficient processing and forging of the spline shaft, so that the forging quality of the single tooth of the spline shaft is higher, and at the same time, it can replace manual flipping forging, with a high degree of automation, and at the same time, the angle of each spline shaft flipping can be changed according to the spline shafts of different specifications, and the applicability is stronger.

[0004] During the forging process of wind turbine shaft parts, precise control of their rotation distance is one of the key factors to ensure processing quality. However, the current control method that relies on independent power equipment at both ends has significant limitations. Specifically, this control method requires that the two drive devices must be highly synchronized and accurately respond to control signals to ensure that the shaft parts maintain completely consistent rotation angles at both ends during rotation. However, in actual operation, due to slight differences between devices, transmission delays in electrical signals, mechanical wear or external interference and other factors, control errors can easily occur. Once accumulated, this error may cause a significant difference in the rotation angles at both ends of the shaft parts, the so-called "torsion offset". This torsional offset will not only affect the geometric accuracy and surface quality of the shaft parts, but will also reduce the connection stability during subsequent assembly and use, and even cause failures.

[0005] In addition, for longer shaft parts, due to their volume and weight limitations, their placement often needs to be changed frequently during the processing process to adapt to different processing requirements. However, the existing relatively fixed structures have many inconveniences during the movement process. First, these fixed structures are often designed to be bulky and difficult to disassemble, resulting in a lot of time and manpower required for repeated disassembly and assembly when moving shaft parts. This inefficient operation not only increases labor intensity, but also prolongs the processing cycle and reduces production efficiency. Secondly, during the movement and fixation process, due to factors such as the operator's experience level, the complexity of the operating environment, and the design defects of the fixed structure itself, positioning errors or loose fixation are very likely to occur. Once these errors occur, they will have a negative impact on the processing accuracy of the shaft parts and may even lead to processing failure or part scrapping.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention organically combines key components such as the base, frame, hydraulic components, pressure plate and shaft parts through an integrated design, thus realizing the continuous forging of wind turbine shafts. This compact and fully functional design not only improves production efficiency, but also reduces floor space, making it easy to flexibly arrange in factories or workshops.

The vertical plate on the connecting plate carries the fixed structure and the adjustment structure. These structures work together to ensure the stability and adjustability of the shaft parts during the forging process.

[0025] 2. The present invention uses the forging die as a bearing component, which not only provides a stable supporting platform for the shaft part, but also allows the vertical plate to move horizontally during the forging process through the opening and the sliding connection plate, so that the shaft part can be accurately displaced and rotated together with the vertical plate during the forging process, ensuring the smooth progress of the forging process. At the same time, the transmission structure between the vertical plate and the forging die ensures the smoothness and accuracy of the movement, improves the forging accuracy, and effectively avoids the displacement or deformation of the shaft part during the forging process.

[0026] 3. The present invention forms a fixed structure through a screw, a movable ring, and a clamping plate, which can firmly clamp the shaft parts to prevent loosening or displacement during the forging process. The threaded connection design of the screw makes the clamping force adjustable and can be adaptively adjusted according to shaft parts of different sizes. In addition, the rotating design of the movable ring in the support plate further enhances the flexibility and durability of the fixed structure and avoids affecting the rotation adjustment of the screw.

[0027] 4. The present invention realizes the function of rotational adjustment of the driving shaft parts during the lifting and lowering of the pressure plate by forming an adjustment structure through the meshing of the ratchet and the push rod, which not only simplifies the operation process, but also improves the accuracy and efficiency of the adjustment. The design of the limit plate and the spring pin shaft provides the push rod with the necessary reset force, ensuring smooth reset after forging is completed.

[0028] 5. The present invention uses a transmission rod to convert the lifting movement of the pressure plate into a drive for the adjustment structure by setting a linkage structure, thereby realizing the simultaneous forging and rotation adjustment, which not only improves the production efficiency, but also ensures the position stability of the shaft parts during the forging process. The sliding connection of the transmission rod inside the pressure plate ensures the smoothness and reliability of the transmission.

[0029] 6. The present invention realizes stable carrying of the upright plate and the transmission rod by setting a carrying structure, ensures that the connection state between the transmission rod and the push rod is not affected during the horizontal movement of the upright plate, enhances the stability and durability of the device, and ensures the reliability of long-term operation.

[0030] 7. The present invention realizes precise control of the vertical plate and the fixed structure and adjustment structure thereon by setting a guide rod and a reciprocating screw. The threaded connection design of the reciprocating screw enables the vertical plate to slide precisely inside the forging die, providing strong support for the horizontal movement of the shaft parts. At the same time, the fixed connection design of the guide rod ensures the stability of the vertical plate during movement and prevents deviation or shaking.

[0031] 8. The present invention realizes the synchronous rotation between the ratchet and the reciprocating screw by setting a transmission mode of pulleys and belts. It not only has high transmission efficiency, but also has a simple structure and convenient maintenance, saving the operating steps of setting up additional driving equipment. At the same time, the flexible connection of the pulley and the belt can also absorb certain vibrations and impacts, protecting the transmission components from damage.

[0032] 9. The present invention provides a chip removal groove, so that the chips generated during the forging process can be discharged in time, thereby avoiding the influence of the chips on the forging process and the quality of the shaft parts.

[0033] 10. The present invention can automatically collect and clean the debris by arranging a push plate and a collection box, thereby reducing the labor intensity of workers and improving the cleanliness of the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] A bearing component 6 is arranged on the top of the base 1. The bearing component 6 is made of high-strength, high-temperature resistant material, such as cast steel or special alloy. A groove matching the shape of the shaft part 5 is designed on the top of the bearing component 6 to ensure that the shaft part 5 can be stably placed during the forging process. The shaft part 5 is placed on the surface of the bearing component 6. A fixing structure 8 is arranged on both sides of the bearing component 6 through an adjusting structure 7. The fixing structure 8 can fix the shaft part 5. The adjusting structure 7 can rotate and adjust the fixing structure 8 together with the shaft part 5. A linkage structure 9 is arranged on the surface of the pressing plate 4.

[0050] refer to Figure 4The bearing component 6 includes a forging die 10 fixedly connected to the top of the base 1, and the shaft part 5 is placed on the top of the forging die 10. An opening 11 is opened on the surface of the forging die 10, and a connecting plate 12 is slidably connected inside the opening 11. A slider or roller matching the edge guide groove of the opening 11 of the forging die 10 is designed at the bottom of the connecting plate 12 to reduce sliding resistance. Vertical plates 13 are fixedly connected on both sides of the connecting plate 12. Reinforcing ribs or ribs are designed on the surface of the vertical plate 13 to improve its overall rigidity and stability. The fixed structure 8 and the adjustment structure 7 are both installed on the surface of the vertical plate 13. The vertical plate 13 is connected to the forging die 10 through a transmission structure 14. The vertical plate 13 can slide inside the forging die 10 using the transmission structure 14 and carry the shaft part 5 for synchronous displacement through the fixed structure 8 during the sliding process.

[0051] As a technical optimization scheme of the present invention, the forging die 10 is used as the bearing component 6, which not only provides a stable supporting platform for the shaft part 5, but also allows the vertical plate 13 to move horizontally during the forging process through the opening 11 and the slidingly connected connecting plate 12, so that the shaft part 5 can be accurately displaced and rotated together with the vertical plate 13 during the forging process, ensuring the smooth progress of the forging process. At the same time, the transmission structure 14 between the vertical plate 13 and the forging die 10 ensures the smoothness and accuracy of the movement, thereby improving the forging accuracy.

[0052] refer to Figure 4 The fixed structure 8 includes a support plate 15 fixedly connected to the inner side of the vertical plate 13, a rotating wheel 16 is arranged on the outer side of the support plate 15, and a movable ring 17 is inlaid inside the support plate 15. The movable ring 17 can rotate inside the support plate 15, and a screw 18 is threadedly connected to the inner side of the rotating wheel 16. One end of the screw 18 close to the support plate 15 passes through the movable ring 17 and is threadedly connected to the movable ring 17. During the rotation of the screw 18, the screw 18 can move inwardly by using the thread. The inner end of the screw 18 is fixedly connected to a clamping plate 19 located on the inner side of the support plate 15, and the inner side of the clamping plate 19 contacts the surface of the shaft part 5. When working, the screw 18 rotates and moves inwardly by the action of the thread, pushing the clamping plate 19 to clamp the shaft part 5.

[0053] As a technical optimization solution of the present invention, the fixed structure 8 composed of a screw 18, a movable ring 17, and a clamping plate 19 can firmly clamp the shaft part 5 to prevent loosening or displacement during the forging process. The threaded connection design of the screw 18 makes the clamping force adjustable and can be adaptively adjusted according to shaft parts 5 of different sizes. In addition, the rotating design of the movable ring 17 in the support plate 15 further enhances the flexibility and durability of the fixed structure 8 and avoids affecting the rotation adjustment of the screw 18.

[0054] refer to Figure 6The adjusting structure 7 includes a ratchet 20 fixedly connected to the surface of the screw 18, a bracket 21 is installed on the outer side of the vertical plate 13 through a carrying structure, and a push rod 22 is movably connected to the bottom of the bracket 21 through a spring pin shaft. The push rod 22 extends to the inside of the ratchet 20 away from the side of the bracket 21 and meshes with the ratchet 20. A limit plate 23 is provided on one side of the push rod 22, and the side of the limit plate 23 away from the push rod 22 is fixedly connected to the surface of the bracket 21. In the process of the hydraulic component 3 driving the pressure plate 4 to rise and fall, the linkage structure 9 can be used to control the synchronous movement of the push rod 22. During operation, the ratchet 20 is fixedly connected to the screw 18, and the push rod 22 is movably connected to the bracket 21 through a spring pin shaft and meshes with the ratchet 20. When the pressure plate 4 is raised or lowered, the push rod 22 is controlled to move through the linkage structure 9, thereby driving the ratchet 20 to rotate, thereby realizing the rotation adjustment of the shaft part 5.

[0055] As a technical optimization solution of the present invention, the adjustment structure 7 is formed by the meshing of the ratchet 20 and the push rod 22, which realizes the function of rotational adjustment of the drive shaft part 5 during the lifting and lowering of the pressure plate 4, which not only simplifies the operation process, but also improves the accuracy and efficiency of the adjustment. The design of the limit plate 23 and the spring pin shaft provides the push rod 22 with the necessary reset force to ensure smooth reset after forging is completed.

[0056] refer to Figure 6 The linkage structure 9 includes a transmission rod 24 slidably connected to the inside of the pressure plate 4. Both ends of the transmission rod 24 pass through the pressure plate 4 and the bracket 21 in sequence and are fixedly connected to the bracket 21. During the lifting and lowering of the pressure plate 4, the transmission rod 24 can be used to drive the bracket 21 to move synchronously. When the pressure plate 4 is lifted or lowered, the transmission rod 24 drives the bracket 21 to move synchronously, thereby controlling the meshing state of the push rod 22 and the ratchet 20, thereby realizing the synchronization of the rotation adjustment of the shaft part 5 and the forging process.

[0057] As a technical optimization scheme of the present invention, by setting a linkage structure 9 and utilizing the transmission rod 24 to convert the lifting movement of the pressure plate 4 into driving the adjustment structure 7, forging and rotation adjustment are carried out simultaneously, which not only improves the production efficiency, but also ensures the position stability of the shaft part 5 during the forging process. The sliding connection of the transmission rod 24 inside the pressure plate 4 ensures the smoothness and reliability of the transmission.

[0058] refer to Figure 6The carrying structure includes a sleeve 25 fixedly connected to the outer side of the vertical plate 13, and the sleeve 25 extends to the outer side of the bracket 21 away from the side of the vertical plate 13. The outer side of the bracket 21 is threadedly connected with a bolt 26, and the bolt 26 is located inside the sleeve 25 and can slide inside the sleeve 25. Both ends of the transmission rod 24 extend to the inside of the sleeve 25 and are slidably connected with the sleeve 25. When the vertical plate 13 moves horizontally through the transmission structure 14, the vertical plate 13 can use the sleeve 25 and the bolt 26 to carry and displace the bracket 21 together with the transmission rod 24, so that the transmission rod 24 slides inside the pressure plate 4 to ensure the connection state between the push rod 22 and the ratchet 20. Wear-resistant pads or sliding bearings are added to the contact surface between the sleeve 25 and the bracket 21 to reduce friction and wear during sliding. Elastic elements such as spring washers are added to the connecting parts of the transmission rod 24, the pressure plate 4 and the bracket 21 to absorb vibration and impact and protect the transmission rod 24 and the connecting parts.

[0059] As a technical optimization solution of the present invention, by setting a carrying structure, the upright plate 13 and the transmission rod 24 are stably carried, ensuring that the connection state between the transmission rod 24 and the push rod 22 is not affected during the horizontal movement of the upright plate 13, thereby enhancing the stability and durability of the device and ensuring the reliability of long-term operation.

[0060] refer to Figure 5 The transmission structure 14 includes a guide rod 27 and a reciprocating screw 28 which are respectively arranged inside the vertical plate 13. The guide rod 27 is fixedly connected to the vertical plate 13, and the reciprocating screw 28 is movably connected to the vertical plate 13 through a bearing. The forging die 10 is sleeved on the surface of the guide rod 27 and the reciprocating screw 28. The forging die 10 is slidably connected to the guide rod 27, and the reciprocating screw 28 is threadedly connected to the forging die 10. The inner wall of the forging die 10 is designed with a slide groove or a threaded hole matching the guide rod 27 and the reciprocating screw 28 to ensure that the die can be smoothly sleeved on the guide rod 27 and the reciprocating screw 28, and realize the sliding connection with the guide rod 27 and the threaded connection with the reciprocating screw 28. During the rotation of the reciprocating screw 28, the fixed structure 8 and the adjustment structure 7 on the carrying surface of the vertical plate 13 can be pushed by the thread to slide and displace inside the forging die 10.

[0061] As a technical optimization solution of the present invention, by setting the guide rod 27 and the reciprocating screw 28, precise control of the vertical plate 13 and the fixed structure 8 and the adjustment structure 7 thereon is achieved. The threaded connection design of the reciprocating screw 28 enables the vertical plate 13 to perform precise sliding displacement inside the forging die 10, providing strong support for the horizontal movement of the shaft part 5. At the same time, the fixed connection design of the guide rod 27 ensures the stability of the vertical plate 13 during movement and prevents deviation or shaking.

[0062] refer to Figure 7The outer end of the reciprocating screw 28 passes through the vertical plate 13 and extends to the outside of the vertical plate 13. Both ends of the reciprocating screw 28 and the outside of the ratchet 20 are fixedly connected with pulleys 29. The surface of the pulley 29 is sleeved with a belt 30. During the rotation of the ratchet 20, the pulley 29 and the belt 30 can be used to drive the reciprocating screw 28 to rotate synchronously. The transmission ratio between the pulleys 29 at both ends of the reciprocating screw 28 and the pulley 29 on the outside of the ratchet 20 is two to one.

[0063] As a technical optimization scheme of the present invention, by setting the transmission mode of the pulley 29 and the belt 30, the synchronous rotation between the ratchet 20 and the reciprocating screw 28 is achieved, which not only has high transmission efficiency, but also has a simple structure and convenient maintenance, and saves the operating steps of setting up additional driving equipment. At the same time, the flexible connection between the pulley 29 and the belt 30 can also absorb certain vibrations and impacts, protecting the transmission components from damage.

[0064] refer to Figure 5 Chip grooves 31 are provided on both sides of the top of the forging die 10, the chip grooves 31 are located on both sides of the shaft part 5, the bottom of the chip grooves 31 is connected with the opening 11, and a connecting groove is provided on the top of the base 1 on the back side of the forging die 10, and the bottom of the connecting groove is connected with the inner wall of the base 1.

[0065] As a technical optimization solution of the present invention, by providing the chip removal groove 31 , the chips generated during the forging process can be discharged in time, thereby avoiding the influence of the chips on the forging process and the quality of the shaft part 5 .

[0066] refer to Figure 1 A plurality of pushing plates 32 are fixedly connected to the interior of the connecting plate 12, and a collecting box 33 is slidably connected to the interior of the base 1. When the forging chips fall into the opening 11 through the chip removal groove 31, the connecting plate 12 during movement can use the pushing plate to push the chips to the outside of the opening 11 and drop them into the collecting box 33 for collection. The collecting box 33 is pushed to the interior of the base 1 by roller sliding and the front end portion is exposed to the outside of the base 1.

[0067] As a technical optimization solution of the present invention, by providing the push plate 32 and the collection box 33, the debris can be automatically collected and cleaned, which reduces the labor intensity of the workers and improves the cleanliness of the working environment.

[0068] The working principle and use process of the present invention are as follows: the wind turbine shaft part 5 is placed on the bearing component 6 on the top of the base 1, that is, the top of the forging die 10. At this time, the fixing structure 8 and the adjusting structure 7 have not yet fixed and adjusted the shaft part 5. The screw 18 is driven to rotate by the rotating wheel 16 in the fixing structure 8. The screw 18 is displaced inside the movable ring 17 by the thread. When the clamping plate 19 inside the screw 18 is in close contact with the two ends of the shaft part 5, the wind turbine shaft part 5 is fixed. The hydraulic assembly 3 starts to work and drives the pressing plate 4 down. In the process of the pressing plate 4 descending, the transmission rod 24 of the linkage structure 9 is connected with the bracket 21, so that the bracket 21 and the adjusting structure 7 thereon including the push rod 22 move synchronously with the pressing plate 4. As the pressing plate 4 descends, the transmission rod 24 in the linkage structure 9 not only drives the bracket 21 to move, but also drives the ratchet 20 to rotate through the meshing relationship between the push rod 22 and the ratchet 20. The ratchet 20 drives the screw 18 to rotate, and the screw 18 that has been fixed cannot continue to move through the screw 18, thereby transmitting the torque to the movable ring 17. , so that the screw 18 carries the movable ring 17 to rotate inside the support plate 15, and the shaft part 5 clamped inside the clamping plate 19 rotates synchronously and changes the forging angle, and the rotation of the ratchet 20 can drive the reciprocating screw 28 to rotate synchronously through the pulley 29 and the belt 30. The rotation of the reciprocating screw 28 uses the thread action to push the vertical plate 13 and the fixed structure 8 thereon and the shaft part 5 to slide inside the forging die 10, so that the bearing assembly has the effect of carrying the shaft part 5 for horizontal displacement during the rotation forging process of the shaft part 5, and further In order to further improve the continuous forging function of the shaft part 5, while the shaft part 5 is rotated and adjusted, the pressing plate 4 continues to descend to forge the shaft part 5. The chips generated during the forging process fall into the opening 11 through the chip groove 31 on the surface of the forging die 10, and are then pushed to the outside of the opening 11 by the pushing plate 32 on the connecting plate 12, and fall into the collecting box 33 under the base 1. After the forging is completed, the hydraulic assembly 3 drives the pressing plate 4 to rise, and drives the bracket 21 and the adjusting structure 7 to reset through the linkage structure 9, and the above steps are repeated to form continuous processing.

[0069] To sum up: the continuous forging device for wind turbine shafts, through an integrated design, organically combines key components such as the base 1, the frame 2, the hydraulic assembly 3, the pressure plate 4 and the shaft part 5, thereby realizing the continuous forging of the wind turbine shaft. This compact and fully functional design not only improves production efficiency, but also reduces the footprint, making it convenient for flexible layout in factories or workshops. At the same time, the adjustment structure 7, the fixed structure 8 and the linkage structure 9 installed on the surface of the base 1 can carry the shaft part 5 to automatically change position and angle during the forging process and form a continuous forging processing effect.
