Description

Technical Field

[0001] This invention relates to the field of flange forging technology, and in particular to a forging apparatus and method for truss tower connecting flanges. Background Technology

[0002] In the flange forging process, the forging table usually adopts a rigid support structure to support the flange forging and withstand the forging impact. However, due to the uneven deformation of the flange forging during the forging process, the traditional rigid support table cannot self-adjust, which can easily lead to uneven contact between the forging and the forging head, affecting the forging quality. In addition, the rigid support has poor buffering capacity against forging impact.

[0003] Therefore, this invention proposes a forging device and method for truss tower connecting flanges to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a forging device for a truss tower connecting flange. This forging device supports the top cover by setting a flexible support mechanism. Utilizing the elastic potential energy of the first damping spring, the top cover is allowed to rotate at a small angle, thereby enabling the top cover to automatically conform to the rolling deviation of the forging. This further increases the fit between the top cover and the forging, allowing the top cover to adapt to the dynamic deformation of the forging during the forging process and ensuring that the contact between the forging, the top cover, and the forging head remains uniform throughout the forging process.

[0005] To achieve the purpose of this invention, the invention is implemented through the following technical solution: a forging device for a truss tower connecting flange, comprising a base and a forging mechanism, wherein the top surface of the base is flush with the ground, the forging mechanism is provided above the base, and a forging table for cooperating with the forging mechanism is provided on the base below the forging mechanism, and a lateral movement mechanism for driving the forging table to move laterally is provided at the bottom of the forging table.

[0006] The forging table includes a movable plate, a top cover, a flexible support mechanism, and a bottom cover. The movable plate is located at the bottom of the bottom cover and is fixedly connected to the bottom cover. The top cover is provided above the bottom cover. A flexible support mechanism is provided at the center between the top cover and the bottom cover. The inner diameter of the top cover is larger than the outer diameter of the bottom cover.

[0007] The flexible support mechanism includes a top plate, a first damping spring, and a bottom plate. The top plate is rotatably connected to the top cover. The bottom plate is located below the top plate. The first damping spring is fixed between the bottom plate and the top plate. Two sets of support columns are also provided between the top plate and the bottom plate. One set of support columns is fixed to the top plate, and the other set of support columns is fixed to the bottom plate. There is a gap between the two sets of support columns.

[0008] A further improvement is that multiple sets of auxiliary support mechanisms are arrayed between the top cover and the bottom cover. The auxiliary support mechanisms are located outside the flexible support mechanism, and a limiting mechanism for limiting the auxiliary support mechanism is provided on the inner side of the auxiliary support mechanism.

[0009] A further improvement is made in that: the auxiliary support mechanism includes a first hinge rod, a second hinge rod, and a second damping spring. The upper end of the first hinge rod is fixedly connected to the top cover, and the lower end of the second hinge rod is fixedly connected to the bottom cover. The lower end of the first hinge rod and the upper end of the second hinge rod are hinged to each other. The connecting end of the first hinge rod and the second hinge rod faces inward. A second damping spring is fixed at the included angle between the first hinge rod and the second hinge rod.

[0010] Further improvements are made in that: the limiting mechanism includes a fixed plate, a limiting block, and an adjusting mechanism. The number of fixed plates is the same as that of the auxiliary support mechanism. A limiting block is provided on the side of the fixed plate facing the auxiliary support mechanism. The limiting block is arc-shaped and is adapted to and limits the connection end of the first hinge rod and the second hinge rod. An adjusting component is provided on the fixed plate to adjust the position of the limiting block. The fixed plate is fixedly connected to the bottom plate. The distance between the fixed plate and the top plate is greater than the distance between the two sets of support columns.

[0011] A further improvement is that the adjustment component includes a hydraulic cylinder, which is fixed on a fixed plate, and the output end of the hydraulic cylinder is fixedly connected to a limit block.

[0012] A further improvement is made in that: the lower end of the top cover is provided with a gear ring, and the base is provided with a gear drive component. The gear drive component is adapted to the gear ring. The gear drive component includes a rack, a movable seat, a first electric push rod, a second electric push rod, and a fixed seat. The fixed seat is fixed on the base, and the first electric push rod is provided on the fixed seat. The top of the fixed seat is provided with a movable seat. The first electric push rod pushes the movable seat to move. The movable seat is L-shaped. A rack is provided above the movable seat. The end of the rack is fixed with a second electric push rod. The second electric push rod is fixedly connected to the movable seat. The second electric push rod pushes the rack to mesh with the gear ring.

[0013] A further improvement is made in that: the transverse movement mechanism includes a threaded rod, a nut sleeve, a sliding groove, a guide rod, a guide sleeve, and a drive motor. The base has symmetrical cavities inside, and the moving plate is located inside the cavity. Sliding grooves are provided on both sides of the cavity. A threaded rod is provided in one set of the sliding grooves, and a guide rod is provided in the other set. The threaded rod is driven by the drive motor. A nut sleeve is provided on the threaded rod, and the nut sleeve is fixedly connected to the side wall of the moving plate. A guide sleeve is slidably installed on the guide rod, and the guide sleeve is also fixedly connected to the side wall of the moving plate.

[0014] A further improvement is made in that: the forging mechanism includes a column, a mounting plate, a hydraulic drive device, and a forging head. The base is symmetrically provided with columns, the top of the columns is fixed with a mounting plate, the mounting plate is provided with a hydraulic drive device, the output end of the hydraulic drive device is fixed with a forging head, and the forging head is located directly above the top cover.

[0015] A further improvement is that: the top cover is provided with a through hole located above the toothed ring, and there are multiple sets of the through hole.

[0016] A forging method for a forging device for truss tower connecting flanges includes the following steps:

[0017] S1. Place the flange forging on the top cover. At this time, the first damping spring is compressed and moves downward to contract. At the same time, the top cover shakes due to the offset of the flange forging. At this time, the amplitude of shaking is reduced by the auxiliary support mechanism.

[0018] S2. The top cover and flange forging are moved by the transverse movement mechanism, so that the flange forging is aligned with the forging head or different positions of the flange forging are forged and rolled.

[0019] S3. The forging mechanism is working. The forging head slowly and continuously moves down to roll and forge the flange forging, rolling the forging into a round disc shape. During the forging process, as the forging head continues to press down, the first damping spring contracts. At this time, the distance between the two sets of support columns continues to decrease until the two sets of support columns are in contact, thus forming a fixed support. At the same time, the flexible support mechanism and the auxiliary support mechanism push the top cover to always conform to the deformation of the forging.

[0020] S4. When the forging head moves up, the top cover resets and drives the gear ring to rotate, thereby rotating the flange forging on the top cover.

[0021] The beneficial effects of this invention are as follows: This invention supports the top cover by setting a flexible support mechanism. Utilizing the elastic potential energy of the first damping spring, the top cover is allowed to rotate at a small angle, thus enabling it to automatically conform to the rolling deviation of the forging. This further increases the fit between the top cover and the forging, allowing the top cover to adapt to the dynamic deformation of the forging during the forging process. This ensures that the contact between the forging, the top cover, and the forging head remains uniform during forging. The first damping spring absorbs the impact during the forging process. Simultaneously, the two sets of support columns in the flexible support mechanism provide flexible support when not in contact, and become rigid load-bearing after the forging head presses down, causing the two sets of support columns to conform. To ensure stable support during forging, multiple auxiliary support mechanisms support the top cover from the outside, improving overall rigidity and stability. The limiting mechanism can flexibly adjust the maximum sway amplitude and tilt angle of the top cover to prevent excessive displacement, protect the central flexible support, and adapt to different working conditions. The lateral movement mechanism and gear drive can realize the lateral movement and rotation of the forging table, facilitating forging and rolling of different positions of the flange forging, improving processing flexibility and efficiency. The present invention has a reasonable structural design, combining flexible adaptive adjustment and rigid stable bearing capacity, significantly improving the processing quality, equipment stability, and applicability of flange forging.

[0024] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0025] according to Figures 1-6 As shown, this embodiment proposes a forging device and method for a truss tower connecting flange, including a base 1 and a forging mechanism. The top surface of the base 1 is flush with the ground. A forging mechanism is provided above the base 1. A forging table for cooperating with the forging mechanism is provided on the base 1 at a position below the forging mechanism. A lateral movement mechanism for driving the forging table to move laterally is provided at the bottom of the forging table.

[0026] The forging table includes a movable plate 2, a top cover 3, a flexible support mechanism, and a bottom cover 4. The movable plate 2 is located at the bottom of the bottom cover 4 and is fixedly connected to the bottom cover 4. The top cover 3 is provided above the bottom cover 4. A flexible support mechanism is provided at the center between the top cover 3 and the bottom cover 4. The inner diameter of the top cover 3 is larger than the outer diameter of the bottom cover 4, and the distance between them is controlled within 2-3 cm.

[0027] The flexible support mechanism includes a top plate 5, a first damping spring 6, and a bottom plate 7. The top plate 5 is rotatably connected to the top cover 3. The bottom plate 7 is located below the top plate 5. The first damping spring 6 is fixed between the bottom plate 7 and the top plate 5. Two sets of support columns 8 are also provided between the top plate 5 and the bottom plate 7. One set of support columns 8 is fixed to the top plate 5, and the other set of support columns 8 is fixed to the bottom plate 7. There is a gap between the two sets of support columns 8.

[0028] This device supports the top cover 3 with a flexible support mechanism. The elastic potential energy of the first damping spring 6 allows the top cover 3 to deflect at a small angle, increasing the fit between the top cover 3 and the forging. This allows the top cover 3 to adapt to the dynamic deformation of the forging during the forging process, ensuring that the contact between the forging, the top cover 3, and the forging head 27 remains uniform during forging. During the forging process, the forging head 27 slowly and continuously moves downwards, continuously crushing the forging. The first damping spring 6 under the top cover 3 protects the equipment and the forging, preventing damage to the equipment and workpiece due to excessive instantaneous load. At the same time, two sets of support columns 8 are set at the bottom of the top cover 3. During the continuous downward movement of the top cover, the two sets of support columns 8 come into contact, allowing the top cover 3 to switch to rigid load-bearing mode, thereby ensuring the stable support of this device.

[0029] Multiple sets of auxiliary support mechanisms are arranged in an array between the top cover 3 and the bottom cover 4. The auxiliary support mechanisms are located on the outside of the flexible support mechanisms, and the inner side of the auxiliary support mechanisms is provided with a limiting mechanism to limit the movement of the auxiliary support mechanisms.

[0030] The auxiliary support mechanism includes a first hinge rod 9, a second hinge rod 10, and a second damping spring 11. The upper end of the first hinge rod 9 is fixedly connected to the top cover 3, and the lower end of the second hinge rod 10 is fixedly connected to the bottom cover 4. The lower end of the first hinge rod 9 and the upper end of the second hinge rod 10 are hinged to each other. The connecting end of the first hinge rod 9 and the second hinge rod 10 faces inward. The second damping spring 11 is fixed at the included angle between the first hinge rod 9 and the second hinge rod 10.

[0031] Multiple auxiliary support mechanisms are set up to support the top cover 3 from the outside, while a limiting mechanism is set on the inside of the auxiliary support mechanism to limit the range of motion of the auxiliary support and prevent excessive shaking. The multi-point support on the outside disperses the force on the top cover 3, improving the overall rigidity and stability. At the same time, the limiting mechanism controls the shaking amplitude to prevent the top cover 3 from excessively shifting and to protect the central flexible support. The upper end of the first hinge rod 9 is connected to the top cover 3, and the lower end of the second hinge rod 10 is connected to the bottom cover 4. The two rods are hinged in the middle to form a swingable link structure, which swings adaptively with the shaking of the top cover 3. The second damping spring 11 connects the angle between the two rods, providing elastic tension and suppressing the swing amplitude. The link structure flexibly follows the posture of the top cover 3 and always maintains support.

[0032] The limiting mechanism includes a fixed plate 12, a limiting block 13, and an adjustment mechanism. The number of fixed plates 12 is the same as that of the auxiliary support mechanism. The fixed plate 12 is provided with a limiting block 13 on the side facing the auxiliary support mechanism. The limiting block 13 is arc-shaped and is adapted to the connection end of the first hinge rod 9 and the second hinge rod 10 for limiting. The fixed plate 12 is provided with an adjustment component for adjusting the position of the limiting block 13. The fixed plate 12 is fixedly connected to the bottom plate 7. The distance between the fixed plate 12 and the top plate 5 is greater than the distance between the two sets of support columns 8.

[0033] The adjustment assembly includes a hydraulic cylinder 14, which is fixed on a fixed plate 12. The output end of the hydraulic cylinder 14 is fixedly connected to a limit block 13, and the hydraulic cylinder 14 is powered by a hydraulic circuit system.

[0034] The limit block 13 is moved by the hydraulic cylinder 14, thereby adjusting the position of the limit block 13 and thus adjusting the maximum swing range of the top cover 3 to meet other working conditions and increase the scope of application.

[0035] The lower end of the top cover 3 is provided with a gear ring 15, and the base 1 is provided with a gear drive component 16. The gear drive component 16 is adapted to the gear ring 15. The gear drive component 16 includes a rack 33, a movable seat 29, a first electric push rod 30, a second electric push rod 31, and a fixed seat 32. The fixed seat 32 is fixed to the base 1. The first electric push rod 30 is provided on the fixed seat 32. The movable seat 29 is provided on the top of the fixed seat 32. The first electric push rod 30 pushes the movable seat 29 to move. The movable seat 29 is L-shaped. The rack 33 is provided above the movable seat 29. The end of the rack 33 is fixed with the second electric push rod 31. The second electric push rod 31 is fixedly connected to the movable seat 29. Push rod 31 pushes rack 33 to mesh with gear ring 15, which in turn drives gear ring 15 to rotate via gear drive component 16, thereby driving top cover 3 to rotate, and then driving forging to rotate, adjusting the position of forging. At the same time, gear drive component 16 forms a linkage with transverse mechanism and forging mechanism. When forging mechanism presses down, second electric push rod 31 drives rack 33 to disengage from gear ring 15. When transverse mechanism is working, it can determine whether forging rotation adjustment is needed based on forging position. If so, rack 33 can remain engaged. As forging table moves, forging rotates synchronously. After transverse mechanism finishes working, first electric push rod 30 readjusts the position. If not, second electric push rod 31 directly separates rack 33 from gear ring 15.

[0036] The transverse assembly includes a threaded rod 17, a nut sleeve 18, a sliding groove 19, a guide rod 20, a guide sleeve 21, and a drive motor 22. The base 1 has symmetrical cavities 23 inside, and the moving plate 2 is located inside the cavity 23. Sliding grooves 19 are provided on both sides of the cavity 23. One set of sliding grooves 19 contains a threaded rod 17, and the other set contains a guide rod 20. The threaded rod 17 is driven by the drive motor 22. A nut sleeve 18 is provided on the threaded rod 17. The nut sleeve 18 is fixedly connected to the side wall of the moving plate 2. The guide sleeve 21 is slidably installed on the guide rod 20. The guide sleeve 21 is also fixedly connected to the side wall of the moving plate 2.

[0037] The rotation of the threaded rod 17 drives the nut sleeve 18 to move, thereby moving the moving plate 2. At the same time, the guide rod 20 limits the movement of the moving plate 2 to ensure stable movement.

[0038] The forging mechanism includes a column 24, a mounting plate 25, a hydraulic drive device 26, and a forging head 27. The column 24 is symmetrically arranged on the base 1. The mounting plate 25 is fixed to the top of the column 24. The hydraulic drive device 26 is arranged on the mounting plate 25. The forging head 27 is fixed to the output end of the hydraulic drive device 26. The forging head 27 is located directly above the top cover 3.

[0039] The top cover 3 is provided with a through hole 28 located above the toothed ring 15. There are multiple sets of through holes 28. These multiple sets of through holes 28 can be used for heat dissipation inside the top cover 3, and can also allow the hydraulic oil circuit system to pass through.

[0040] The forging method using the forging apparatus described above for truss tower connecting flanges includes the following steps:

[0041] S1. Place the flange forging on the top cover 3. At this time, the first damping spring 6 is compressed and moves downward to contract. At the same time, the top cover 3 shakes due to the offset of the flange forging. At this time, the amplitude of shaking is reduced by the auxiliary support mechanism.

[0042] S2. The top cover 3 and the flange forging are moved by the transverse movement mechanism, so that the flange forging is aligned with the forging head 27 or different positions of the flange forging are forged and rolled.

[0043] S3. The forging mechanism is working. The forging head 27 slowly and continuously moves down to roll and forge the flange forging, rolling the forging into a round disc shape. During the forging process, as the forging head 27 continues to press down, the first damping spring 6 contracts. At this time, the distance between the two sets of support columns 8 continues to decrease until the two sets of support columns 8 are in contact, thus forming a fixed support. At the same time, the flexible support mechanism and the auxiliary support mechanism push the top cover 3 to always conform to the deformation of the forging.

[0044] S4. When the forging head 27 moves upward, the top cover 3 is reset, and the gear drive component 16 drives the gear ring 15 to rotate, thereby rotating the flange forging on the top cover 3.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
