Description

Technical Field

[0001] This utility model relates to the field of rotary worktable technology, specifically a rotary worktable for forging and upsetting wind turbine flanges. Background Technology

[0002] The rotary table for forging and upsetting wind turbine flanges is a piece of equipment specifically designed for the forging and upsetting process of wind turbine flanges. It can stably rotate the wind turbine flanges during the forging process to meet the process requirements. The rotary table is usually composed of a forging and upsetting placement platform, a rotating chassis, a support structure, and a drive device. The forging and upsetting placement platform is used to support the wind turbine flanges, the support structure ensures the stability and load-bearing capacity of the worktable, and the drive device provides rotational power. During the forging and upsetting process of wind turbine flanges, the rotary table is started by the drive device, which drives the rotating chassis, the forging and upsetting placement platform, and the wind turbine flanges to rotate.

[0003] In existing rotary worktables for forging and upsetting wind turbine flanges, the large weight of the wind turbine flange and the high friction between the forging and upsetting platform and the rotary base cause accelerated wear and shorten their service life. Furthermore, the weight of the wind turbine flange combined with the high friction results in significant resistance during rotation, hindering smooth operation. This unstable rotation leads to uneven stress on the wind turbine flange during forging, ultimately affecting forging quality and the final performance of the product. Utility Model Content

[0004] This utility model provides a rotary worktable for forging and upsetting wind turbine flanges. It has the advantages of easy rotation and low friction generated during rotation, thus solving the problem of wear caused by the large friction generated when the rotary worktable for forging and upsetting wind turbine flanges drives the heavy wind turbine flanges.

[0005] To achieve a rotary worktable for forging and upsetting wind turbine flanges that allows for convenient rotation and minimizes friction, this utility model provides the following technical solution: A rotary worktable for forging and upsetting wind turbine flanges includes a forging and upsetting worktable. The worktable has an internal rotating cavity. A rotating base is movably mounted on the inner wall of the rotating cavity. A forging and upsetting placement platform is mounted on the top surface of the rotating base. The outer surface of the rotating base has uniformly distributed external grooves, and external rollers are movably mounted on the inner walls of several of these external grooves. The inner surface of the rotating base has uniformly distributed internal grooves, and internal rollers are movably mounted on the inner walls of several of these internal grooves. The bottom surface of the rotating base has a bottom groove, and lower rollers are movably mounted on the inner wall of this bottom groove.

[0006] As a preferred embodiment of this utility model, the outer surface of the outer roller, the outer surface of the outer roller, and the outer surface of the outer roller are all in active contact with the inner wall of the rotating cavity.

[0007] As a preferred embodiment of this utility model, a bottom column is mounted on the bottom surface of the rotating chassis, and a first ball shaft is mounted on the bottom surface of the bottom column.

[0008] As a preferred technical solution of this utility model, the forging and upsetting worktable has a first ball groove inside, and the inner wall of the first ball groove is in contact with the outer surface of the first ball shaft.

[0009] As a preferred technical solution of this utility model, the top surface of the forging and upsetting worktable is uniformly provided with second ball grooves, and a second ball shaft is movably installed on the inner wall of several second ball grooves.

[0010] As a preferred embodiment of this utility model, the outer surfaces of several second ball shafts are in movable contact with the bottom surface of the forging upsetting platform, and a helical gear ring is installed on the bottom surface of the rotating chassis.

[0011] As a preferred technical solution of this utility model, a motor is installed inside the forging upsetting worktable, a rotating shaft is installed on the outer surface of the output end of the motor, a support plate is installed inside the forging upsetting worktable, one end surface of the rotating shaft is in movable contact with the inside of the support plate, and a driving helical gear is installed on the outer surface of the rotating shaft, and the outer surface of the driving helical gear meshes with the outer surface of the helical gear ring.

[0012] Compared with the prior art, this utility model provides a rotary worktable for forging and upsetting wind turbine flanges, which has the following advantages:

[0013] This rotary worktable for forging and upsetting wind turbine flanges utilizes a combination of a first ball shaft, a second ball shaft, outer rollers, inner rollers, a lower roller, a first ball groove, and a second ball groove. This transforms static friction between the rotating chassis and the forging and upsetting placement table and the forging and upsetting worktable into rolling friction. This significantly reduces starting resistance, making it easier to rotate heavier wind turbine flanges. The rolling friction is further dispersed and reduced by the rolling of the outer, inner, and lower rollers, thus reducing wear on the contact surfaces. This helps extend the equipment's service life, lower maintenance costs, and reduce vibration and noise caused by friction. The rotating chassis and forging and upsetting placement table are also more stable during rotation, contributing to improved machining accuracy and product quality. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4This utility model discloses a rotary worktable for forging and upsetting wind turbine flanges, including a forging and upsetting worktable 1. The worktable 1 has a rotating cavity 3 inside, and a rotating base 11 is movably mounted on the inner wall of the rotating cavity 3. A forging and upsetting placement platform 2 is mounted on the top surface of the rotating base 11. External grooves 12 are evenly distributed on the outer surface of the rotating base 11, and external rollers 14 are movably mounted on the inner walls of several external grooves 12. Internal grooves 13 are evenly distributed on the inner surface of the rotating base 11. Several inner rollers 16 are movably installed on the inner walls of the built-in grooves 13. A bottom groove 15 is formed on the bottom surface of the rotating base 11. Lower rollers 17 are evenly movably installed on the inner wall of the bottom groove 15. The outer surfaces of the outer rollers 14, the outer surfaces of the outer rollers 14, and the outer surfaces of the outer rollers 14 are all in contact with the inner wall of the rotating cavity 3, changing from static friction to rolling friction. This reduces the friction between the rotating base 11 and the forging upsetting placement table 2 and the forging upsetting worktable 1, thereby facilitating the operation of the wind turbine. When a flange rotates, static friction is usually greater than dynamic friction, and starting static friction requires overcoming significant resistance. By changing the friction mode from static friction to rolling friction, the resistance during startup can be significantly reduced, making it easier to rotate heavier wind turbine flanges. The resistance of rolling friction is much less than that of static friction. Therefore, the rotating chassis 11 and the forging upsetting platform 2 consume less energy and are more efficient during rotation, which helps save energy and improve the overall efficiency of the production line. Static friction easily leads to wear on the contact surfaces, while rolling friction disperses and reduces friction through the rolling of the outer roller 14, inner roller 16, and lower roller 17, thereby reducing wear on the contact surfaces, helping to extend the service life of the equipment, and reducing maintenance costs. The contact area of ​​rolling friction is small, and the outer roller 14, inner roller 16, and lower roller 17 can maintain a certain gap during rolling, which helps to reduce vibration and noise caused by friction. The rotating chassis 11 and the forging upsetting platform 2 are more stable during rotation, which helps to improve processing accuracy and product quality.

[0021] A base column 8 is mounted on the bottom surface of the rotating chassis 11, and a first ball bearing 9 is mounted on the bottom surface of the base column 8. A first ball groove 18 is formed inside the forging upsetting worktable 1, and the inner wall of the first ball groove 18 is in contact with the outer surface of the first ball bearing 9. Second ball grooves 19 are evenly formed on the top surface of the forging upsetting worktable 1, and second ball bearings 10 are movably mounted on the inner walls of several second ball grooves 19. The outer surfaces of several second ball bearings 10 are in contact with the bottom surface of the forging upsetting placement table 2. A helical gear ring 20 is mounted on the bottom surface of the forging upsetting worktable 1. A motor 4 is installed inside the forging upsetting worktable 1. A rotating shaft 5 is mounted on the outer surface of the output end of the motor 4. A support plate 6 is installed inside the forging upsetting worktable 1. One end surface of the rotating shaft 5 is in movable contact with the inside of the support plate 6. A driving helical gear 7 is mounted on the outer surface of the rotating shaft 5. The outer surface of the driving helical gear 7 meshes with the outer surface of the helical gear ring 20. The motor 4 drives the rotating shaft 5 to rotate. One end surface of the rotating shaft 5 is in contact with the support plate 6. The internal moving contact of plate 6 allows the rotating shaft 5 to stably drive the driving helical gear 7 to rotate. The outer surface of the driving helical gear 7 meshes with the outer surface of the helical gear ring 20, thereby allowing the helical gear ring 20 to stably drive the rotating chassis 11 to rotate. The rotating chassis 11 drives the outer roller 14, inner roller 16, and lower roller 17 to rotate. The outer surfaces of the outer roller 14, inner roller 16, and lower roller 17 make moving contact with the inner wall of the rotating cavity 3, thereby allowing the outer roller 14 to move in the outer groove. 12. The inner roller 16 rotates in the inner groove 13 and the lower roller 17 rotates in the bottom groove 15, thereby reducing the friction between the rotating base 11 and the forging upsetting worktable 1. The rotating base 11 drives the forging upsetting placement table 2 and the bottom column 8 to rotate synchronously. The bottom column 8 drives the first ball shaft 9 to rotate in the first ball groove 18. The bottom surface of the forging upsetting placement table 2 is in contact with the outer surface of several second ball shafts 10, and several second ball shafts 10 rotate in the second ball groove 19.

[0022] The working principle and usage process of this utility model are as follows: When the heated wind turbine flange needs to be forged and upset, a crane is used to place the wind turbine flange into the forging and upset placement platform 2. When the wind turbine flange needs to be rotated, due to its weight, the controller controls the motor 4 to work. The motor 4 drives the rotating shaft 5 to rotate. One end of the rotating shaft 5 is in contact with the inside of the support plate 6, thereby stably driving the drive helical gear 7 to rotate. The outer surface of the drive helical gear 7 meshes with the outer surface of the helical gear ring 20, thereby stably driving the rotating chassis 11 to rotate. The rotating base 11 drives the outer roller 14, inner roller 16, and lower roller 17 to rotate. The outer surfaces of the outer roller 14, inner roller 16, and lower roller 17 make contact with the inner wall of the rotating cavity 3, so that the outer roller 14 rotates in the outer groove 12, the inner roller 16 rotates in the inner groove 13, and the lower roller 17 rotates in the bottom groove 15. This reduces the friction between the rotating base 11 and the forging upsetting worktable 1. The rotating base 11 drives the forging upsetting placement table 2 and the bottom column 8 to rotate synchronously. The bottom column 8 drives the first ball shaft 9 to rotate in the first ball groove 18. The bottom surface of the forging upsetting placement table 2 makes contact with several second balls. The outer surface of shaft 10 is in active contact, and several second ball shafts 10 rotate within the second ball groove 19, thereby reducing the friction between the rotating chassis 11 and the forging upsetting platform 2 and the forging upsetting worktable 1, changing from static friction to rolling friction. This facilitates the rotation of the wind turbine flange. Static friction is usually greater than dynamic friction, and starting static friction requires overcoming significant resistance. By changing the friction mode from static friction to rolling friction, the resistance during startup can be significantly reduced, making it easier to rotate the heavier wind turbine flange. The resistance of rolling friction is much smaller than that of static friction. Therefore, the rotating chassis 11 and the forging upsetting platform 2 rotate more smoothly during operation. Lower energy consumption and higher efficiency help save energy and improve the overall efficiency of the production line. Static friction easily leads to wear on the contact surface, while rolling friction disperses and reduces friction through the rolling of the outer roller 14, inner roller 16 and lower roller 17, thereby reducing wear on the contact surface, helping to extend the service life of the equipment and reduce maintenance costs. The contact area of ​​rolling friction is small, and the outer roller 14, inner roller 16 and lower roller 17 can maintain a certain gap during rolling, which helps to reduce vibration and noise caused by friction. The rotating chassis 11 and the forging upsetting placement table 2 are more stable when rotating, which helps to improve processing accuracy and product quality.
