Description

Technical Field

[0001] This application relates to the field of heat treatment of materials, and in particular to a heat treatment device for strengthening and toughening wind turbine flange forgings. Background Technology

[0002] In the machinery manufacturing sector, the booming development of the wind power industry has become a significant force driving the optimization and upgrading of the energy structure. With the continuous increase in global demand for clean energy, wind power equipment is rapidly developing towards larger scale and higher efficiency. As an indispensable key connecting component in wind power equipment, the quality and performance of wind turbine flanges are crucial, directly determining the stability and reliability of the entire wind power system. High-quality wind turbine flange forgings are not only the cornerstone of ensuring the stable operation of wind turbine generators but also the key to improving power generation efficiency and extending equipment lifespan. In recent years, with the continuous expansion of the wind power industry, the market demand for wind turbine flanges has experienced explosive growth. This undoubtedly brings unprecedented challenges and opportunities to the industry, prompting industry professionals to continuously explore and innovate, dedicating themselves to the technological research and development of improving the performance of wind turbine flange forgings.

[0003] Currently, a variety of methods are commonly used for the heat treatment of large wind turbine flange forgings to enhance their toughness. The traditional method of integral heating involves placing the large wind turbine flange forging in a large furnace for overall heating, followed by subsequent processes such as quenching. This method is simple to operate and suitable for processing larger forgings. Some companies use small flame torches or induction heating coils for localized heating, targeting specific areas of the wind turbine flange to meet the performance requirements of different parts. Other companies employ a cooling medium spraying method, precisely controlling the cooling rate to optimize the microstructure of the forging, thereby enhancing its strength and toughness.

[0004] Regarding the aforementioned technologies, existing heat treatment methods have significant drawbacks. In the processing of large wind turbine flange forgings, traditional overall heating methods struggle to precisely control the temperature and heating time of different parts, easily leading to localized overheating or uneven heating, severely impacting the overall performance of the forging. While localized heating tools can provide targeted heating, they struggle to ensure uniform and consistent heating for large, complex-shaped wind turbine flanges. Furthermore, existing heating and cooling devices lack flexibility and cannot effectively adapt to large wind turbine flange forgings of different specifications and sizes, significantly limiting further improvements in production efficiency and product quality. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a heat treatment apparatus for strengthening and toughening wind turbine flange forgings.

[0006] This application provides a heat treatment device for strengthening and toughening wind turbine flange forgings, which adopts the following technical solution:

[0007] A heat treatment device for strengthening and toughening wind turbine flange forgings includes a support mechanism; a spraying mechanism mounted on the support mechanism; a first heating mechanism mounted on the spraying mechanism; and a second heating mechanism mounted on the support mechanism. The second heating mechanism includes a rotating motor mounted on the support mechanism, with a rotating shaft at its transmission end. The rotating shaft is vertically oriented and has an mounting assembly connected to it via a connecting assembly. The mounting assembly is connected to the support mechanism and also includes a locking assembly. A plurality of heating rods are slidably connected to the mounting assembly, and these heating rods are evenly distributed in a circular array around the rotating shaft. The device also includes an adjustment assembly mounted on the rotating shaft, located on the side of the mounting assembly pointing towards the ground, which controls the movement of the heating rods.

[0008] By adopting the above technical solutions, this wind turbine flange forging strengthening and toughening heat treatment device has several advantages. The support mechanism provides stable support for the entire device, ensuring stable operation. The spraying mechanism, mounted on the support mechanism, can spray the flanges during processing, effectively cooling them or applying specific treatment fluids, which helps improve the performance of the flange forgings. The first heating mechanism, mounted on the spraying mechanism, can heat the flanges during spraying, making the heat treatment process more precise and controllable. The rotating motor of the second heating mechanism drives the rotating shaft to rotate, which in turn rotates the mounting components, allowing the heating rods to be distributed and rotated in a circular array around the rotating shaft, achieving uniform heating of different positions on the flange. The connecting components ensure a reliable connection between the mounting components and the rotating shaft, facilitating power transmission. The locking components secure the mounting components, enhancing the stability of the device. The adjusting components control the movement of the heating rods, allowing flexible adjustment of the heating position according to flanges of different sizes and shapes, improving the applicability and flexibility of the device, and better meeting the needs of wind turbine flange forging strengthening and toughening heat treatment.

[0009] Preferably, the support mechanism includes a first support plate, a support compartment is provided on the first support plate, a support telescopic rod is vertically provided on one side of the first support plate, a second support plate is provided on the support telescopic rod, and the rotating motor is provided on the second support plate.

[0010] By adopting the above technical solution, the first support plate is used to support the support chamber and the support telescopic rod. The support chamber can provide installation space for other components, and the support telescopic rod can adjust the height of the second support plate so that the rotating motor can be in a suitable position and the heating rod can be moved to a suitable position, thereby providing stable support for the rotation of the second heating mechanism and ensuring the normal operation of the entire wind power flange forging strengthening heat treatment device.

[0011] Preferably, the spraying mechanism includes a spraying chamber disposed within the support chamber, a spraying pipe disposed on the spraying chamber, the spraying pipe being vertically disposed, a spraying head disposed on the spraying pipe, and a plurality of spraying holes evenly distributed on the spraying head, the spraying holes pointing towards the flange being processed.

[0012] By adopting the above technical solution, the support chamber can hold the spray chamber. The liquid in the spray chamber can be transmitted to the spray head through the spray pipe, and then sprayed evenly from the spray hole pointing to the flange in the treatment process to treat the flange.

[0013] Preferably, the first heating mechanism includes a base rod disposed on the spray pipe, the base rod having a plurality of connection holes, and a first heating component connected to the base rod, the heating end of the first heating component pointing towards the flange being processed.

[0014] By adopting the above technical solution, a base rod is set on the spray head and connected to the first heating component, with the heating end of the first heating component pointing towards the flange being processed. The flange being processed can be heated. In conjunction with the support mechanism and the second heating mechanism, a more comprehensive strengthening and toughening heat treatment can be achieved for the wind power flange forging. At the same time, when water is sprayed by the spray mechanism, the first heating mechanism can cause the water to vaporize and carry away the heat to achieve rapid cooling, which is beneficial to improving the efficiency and quality of heat treatment.

[0015] Preferably, the heating assembly includes a mounting portion mounted on the base rod through the connecting hole, and a contour heating plate is provided on the mounting portion, the contour heating plate pointing towards the flange being processed.

[0016] By adopting the above technical solution, the support mechanism can support the entire device; the spraying mechanism can spray substances onto the flange being processed; the first heating mechanism heats the flange using the base rod, connecting holes, and heating components; the second heating mechanism can rotate the mounting components by rotating the motor to drive the rotating shaft, and adjust the components to control the movement of the heating rods to achieve flexible heating; the mounting part of the heating components is installed on the base rod through the connecting holes, and the contour heating plate on it points towards the flange being processed, which can conform to the shape of the flange for targeted heating, improve the heating effect and efficiency, and more accurately perform toughening heat treatment on the wind power flange forgings.

[0017] Preferably, the mounting assembly includes a mounting plate connected to the rotating shaft via a connecting component.

[0018] By adopting the above technical solution, the mounting plate of the mounting component is connected to the rotating shaft through the connecting component and can rotate with the rotating shaft. The mounting groove and sliding block on the mounting plate allow the heating rod to slide, which is convenient for adjusting the position. The contour block on the mounting rod cooperates with the T-shaped sliding groove on the support mechanism to ensure the stable rotation of the mounting plate, thereby keeping the heating rod stable when rotating, which helps to uniformly heat the wind power flange forging and improve the heat treatment effect.

[0019] Preferably, the connecting assembly includes a plurality of locking slots disposed on the mounting plate, and a plurality of connecting springs disposed on the rotating shaft. One end of the connecting spring is connected to the rotating shaft, and the other end of the connecting spring is connected to a connecting plate. A rotating roller is rotatably connected to the connecting plate, and the rotating roller can move into the locking slot.

[0020] By adopting the above technical solution, the connecting component can work with the locking component to effectively control the position or rotation of the heating rod. The connecting spring allows the rotating roller to be stably locked into the locking groove, and the rotating shaft can rotate with the mounting plate. When the locking component is locked, the mounting plate cannot rotate, and the rotating roller rotates to separate the mounting plate from the rotating shaft. When the mounting plate is locked, the rotating shaft still rotates with the adjusting component, thereby adjusting the distance between adjacent heating rods.

[0021] Preferably, the locking assembly includes a first locking groove disposed on the mounting plate, the first locking groove having a plurality of first locking protrusions, and a plurality of electric telescopic rods disposed on the support mechanism, the electric telescopic rods having a second locking ring, the second locking ring having a plurality of second locking protrusions.

[0022] By adopting the above technical solution, the mounting plate is provided with a first locking groove and a first locking protrusion. In conjunction with the second locking ring with a second locking protrusion driven by the electric telescopic rod on the support mechanism, the position of the mounting plate can be effectively locked.

[0023] Preferably, the adjustment assembly includes an adjustment disk disposed on the rotating shaft, the adjustment disk having a plurality of adjustment slots, and the heating rod passing through the adjustment slots and corresponding to each adjustment slot.

[0024] By adopting the above technical solution, when the adjusting disc rotates with the rotating shaft, the position of the heating rod can be controlled and adjusted by the adjusting groove, so as to realize the heating of different positions of the wind power flange forging, meet different heat treatment requirements, and improve the flexibility and applicability of the heat treatment device.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a reference device for strengthening and toughening heat treatment of wind turbine flange forgings. Figure 1 It includes a support mechanism 1, a spraying mechanism 2, a first heating mechanism 3, and a second heating mechanism 4. The spraying mechanism 2 is mounted on the support mechanism 1, the first heating mechanism 3 is mounted on the spraying mechanism 2, and the second heating mechanism 4 is mounted on the support mechanism 1. This arrangement enables the mechanisms to work together and perform heat treatment on the wind turbine flange forgings from different angles and in different ways, thereby improving the effect and efficiency of heat treatment.

[0037] In practice, the flange is transported to the support mechanism 1 by external equipment or manual labor. Then, the first heating mechanism 3 and the second heating mechanism 4 heat treat the flange. The spraying mechanism 2 sprays quenching liquid onto the flange as needed. After the heat treatment is completed, the heat-treated flange is removed by external equipment or manual labor.

[0038] refer to Figure 1 Specifically, the support mechanism 1 includes a first support plate 101 and a support chamber 102. The first support plate 101 serves to bear and support the entire device. It is generally a flat plate with a certain strength and stability, and can be made of metal, such as carbon steel, or high-strength aluminum alloy. The support chamber 102 is set on the first support plate 101. A support telescopic rod 103 is vertically set on one side of the first support plate 101. The support telescopic rod 103 can be a hydraulic telescopic rod or an electric telescopic rod, which can realize the telescopic function. The drive end of the support telescopic rod 103 is set on a second support plate 104, and the second heating mechanism 4 is set on the second support plate 104. The height position of the second heating mechanism 4 can be adjusted by extending and retracting the support telescopic rod 103.

[0039] In operation, the support mechanism 1 works as follows: The first support plate 101 is firmly placed on the ground or other foundation surface, bearing the weight of the entire device. The support compartment 102 is installed on the first support plate 101, providing storage space for the equipment inside. The support telescopic rod 103 extends and retracts according to actual needs. When loading or unloading flanges, the support telescopic rod 103 moves the second support plate 104 upwards. During heating, it drives the second support plate 104 to move up and down. Simultaneously, the height is adjusted according to different flange specifications to adapt to the heat treatment requirements of wind power flange forgings of different heights.

[0040] refer to Figure 2The spraying mechanism 2 includes a spraying chamber 201 housed within a support chamber 102. The spraying chamber 201 can be a sealed container used to store quenching fluid. A spraying pipe 202 is installed on the spraying chamber 201. The spraying pipe 202 is vertically oriented and is generally cylindrical, used to transport the quenching fluid; it can be made of metal. A spraying head 204 is installed on the spraying pipe 202, and a spraying pump 203 is also installed on the spraying pipe 202. The spraying head 204 is typically a disc-shaped structure with several evenly distributed spray holes 205, which point towards the flange being processed.

[0041] When the spraying mechanism 2 is in operation: when it is necessary to cool the wind power flange forging, the quenching liquid stored in the spraying chamber 201 is powered by the spraying pump 203 and further transported to the spraying head 204 through the spraying pipe 202. Then, it is sprayed out through the spraying holes 205 evenly distributed on the spraying head 204. The quenching liquid is accurately sprayed onto the flange being processed to achieve the cooling treatment of the flange.

[0042] refer to Figure 2 as well as Figure 3 The first heating mechanism 3 includes a base rod 301 mounted on the spray pipe 202. The base rod 301 is horizontally positioned and can be a metal rod used to mount the first heating component 303. The base rod 301 has several connection holes 302, which are the mounting positions for the first heating component 303. The first heating component 303 is mounted on the base rod 301 through the connection holes 302, with its heating end pointing towards the flange being processed. The first heating component 303 includes a mounting part 3031 mounted on the base rod 301 through the connection holes 302. The mounting part 3031 can be a threaded connector for easy connection to the base rod 301. A contoured heating plate 3032 is mounted on the mounting part 3031. The shape of the contoured heating plate 3032 can be designed according to the shape of the flange, typically fan-shaped, so that the heat emitted can better conform to the flange, improving the uniformity and effect of heating. The 3032 contour heating plate can use resistance heating, with an internal heating resistance wire that generates heat when energized.

[0043] When the first heating mechanism 3 is in operation: current is passed through the heating resistance wire inside the conformal heating plate 3032, the heating resistance wire heats up, and the heat is transferred to the conformal heating plate 3032. Since the conformal heating plate 3032 is designed according to the shape of the flange, it can fit the flange well, thereby heating the flange evenly. The base rod 301 provides installation support for the first heating component 303. The mounting part 3031 securely installs the conformal heating plate 3032 on the base rod 301 through a threaded connection. The installation position of the first heating component is adjusted according to the flange of different specifications.

[0044] refer to Figures 1-5 The second heating mechanism 4 includes a rotary motor 401 mounted on the support mechanism 1. The drive end of the rotary motor 401 has a rotating shaft 402, which is vertically positioned. A mounting assembly 404 is mounted on the rotating shaft 402 via a connecting assembly 403, and the mounting assembly 404 is connected to the support mechanism 1. The mounting assembly 404 includes a mounting plate 4041 connected to the rotating shaft 402 via the connecting assembly 403. The mounting plate 4041 is a circular flat plate structure used for mounting other components. Figure 2 As shown, the mounting plate 4041 has several mounting grooves 4042 at the end pointing to the ground. Each mounting groove 4042 is a recess in the mounting plate 4041, and its shape and size are adapted to the sliding block 4043. A sliding block 4043 is slidably connected within the mounting groove 4042. The sliding block 4043 is generally cuboid in shape and can slide within the mounting groove 4042. A heating rod 406 is connected to the sliding block 4043. The heating rod 406 can also be a resistance heater, capable of heating the flange. Several mounting rods 4044 are provided on the side of the mounting plate 4041 pointing to the second support plate 104. Each mounting rod 4044 can be a cylindrical metal rod used to mount the contour block 4045. The mounting rod 4044 is provided with a contour block 4045, the shape of which is designed according to the shape of the T-shaped sliding groove 4046 on the second support plate 104. It also includes the T-shaped sliding groove 4046 provided on the support mechanism 1. The contour block 4045 is slidably connected in the T-shaped sliding groove 4046, so that the mounting plate 4041 can slide smoothly along the T-shaped sliding groove 4046 when rotating, so that the mounting plate 4041 can rotate around the rotating shaft 402 as the axis. The rotating shaft 402 is provided with a power supply ring 4047, and the mounting plate 4041 is provided with a plurality of brushes 4048. A conductive slip ring 408 is provided between the rotating motor 401 and the rotating shaft 402. The fixed end of the conductive slip ring 408 is provided on the housing of the rotating motor 401, and the movable end of the conductive slip ring 408 is provided on the rotating shaft 402.

[0045] When the second heating mechanism 4 is in operation: after the rotating motor 401 is started, it drives the rotating shaft 402 to rotate. The rotating shaft 402 drives the mounting plate 4041 to rotate through the connecting component 403. The contour block 4045 on the mounting plate 4041 slides in the T-shaped sliding groove 4046 of the support mechanism 1 to ensure that the mounting plate 4041 rotates smoothly, driving the heating rod 406 connected to it to rotate. The heating rod 406 heats the flange through resistance heating. While the rotating shaft 402 rotates, the adjusting component 407 controls the heating rod 406 to move further, so as to achieve precise adjustment of the heating position on the one hand, and adaptive adjustment for flanges of different specifications on the other hand.

[0046] refer to Figure 4The connecting assembly 403 includes several locking slots 4031 disposed on the mounting plate 4041, each slot being a groove formed in the mounting plate 4041. It also includes several connecting springs 4032 disposed on the rotating shaft 402. The connecting springs 4032 can be helical springs, possessing elasticity and telescopicity. One end of each connecting spring 4032 is connected to the rotating shaft 402, and the other end is connected to a connecting plate 4033. The connecting plate 4033 is a C-shaped plate used to connect a rotating roller 4034. The rotating roller 4034 is rotatably connected to the connecting plate 4033, and is vertically positioned. The rotating roller 4034 can move into the locking slots 4031. When the rotating shaft 402 rotates, the mounting plate 4041 rotates due to the interaction between the connecting springs 4032 and the rotating roller 4034 with the locking slots 4031.

[0047] When the connecting assembly 403 is in operation: As the rotating shaft 402 rotates, the connecting spring 4032 will swing and extend accordingly. The rotating roller 4034 on the connecting plate 4033 at the other end of the connecting spring 4032 will fall into the locking groove 4031 of the mounting plate 4041. The movement of the rotating roller 4034 in the locking groove 4031 drives the mounting plate 4041 to rotate, realizing the power transmission between the rotating shaft 402 and the mounting plate 4041. The connecting assembly 403 can cooperate with the locking assembly 405 to achieve the control of the heating rod. 406 effectively controls the position or rotation. Normally, the rotating shaft 402 can rotate with the mounting plate 4041 via the connecting spring 4032. When the locking assembly 405 is locked, the mounting plate 4041 cannot rotate, and the rotating roller 4034 rotates, further separating the mounting plate 4041 from the rotating shaft 402. Even when the mounting plate 4041 is locked, the rotating shaft 402 still drives the adjusting assembly 407 to rotate, thereby adjusting the distance between adjacent heating rods 406 through the adjusting assembly 407.

[0048] refer to Figure 2The locking assembly 405 includes a first locking groove 4051 disposed on the mounting plate 4041. The first locking groove 4051 is an annular structure with a plurality of first locking protrusions 4052, each with a triangular cross-section. It also includes a plurality of electrically operated telescopic rods 4053 disposed on the support mechanism 1. The electrically operated telescopic rods 4053 can extend and retract according to a control signal. A second locking ring 4054 is disposed on each of the electrically operated telescopic rods 4053. The second locking ring 4054 has a plurality of second locking protrusions 4055, each with a triangular cross-section. When it is necessary to fix the mounting plate 4041, the electrically operated telescopic rods 4053 extend, causing the second locking protrusions 4055 on the second locking ring 4054 to engage with the first locking protrusions 4052 on the first locking groove 4051, thus achieving the locking function.

[0049] refer to Figure 2 When the locking assembly 405 is in operation: when it is necessary to fix the mounting plate 4041, it sends a control signal to the electric telescopic rod 4053 to extend. The electric telescopic rod 4053 extends, driving the second locking ring 4054 to approach the first locking groove 4051 until the second locking protrusion 4055 on the second locking ring 4054 and the first locking protrusion 4052 on the first locking groove 4051 engage with each other, fixing the mounting plate 4041. When it is necessary for the mounting plate 4041 to rotate, the electric telescopic rod 4053 retracts, releasing the engagement state.

[0050] refer to Figure 2 The adjustment assembly 407 includes an adjustment disk 4071 mounted on the rotating shaft 402. The adjustment disk 4071 is a disc-shaped structure with several adjustment slots 4072. The heating rod 406 passes through each adjustment slot 4072, corresponding to one slot in turn. When the rotating shaft 402 rotates, the adjustment disk 4071 also rotates, exerting a force on the heating rod 406 through the adjustment slots 4072, thereby controlling the movement of the heating rod 406 and adjusting its heating position.

[0051] When the adjustment component 407 is in operation: when the rotating shaft 402 rotates, the adjustment disk 4071 rotates synchronously. The adjustment groove 4072 on the adjustment disk 4071 will generate relative displacement with the heating rod 406 passing through it. The edge of the adjustment groove 4072 applies a force to the heating rod 406, pushing the heating rod 406 to slide in the mounting groove 4042 of the mounting plate 4041, thereby controlling the movement of the heating rod 406 and realizing precise adjustment of the heating position.

[0052] The implementation principle of the wind turbine flange forging strengthening heat treatment device in this embodiment is as follows: The wind turbine flange forging strengthening heat treatment device in this embodiment provides stable support and reasonable layout for the entire device through the support mechanism 1. The spraying mechanism 2 can cool the flange. The first heating mechanism 3 and the second heating mechanism 4 heat the flange from different angles. The rotating motor 401 in the second heating mechanism 4 drives the rotating shaft 402 to rotate. Through the coordinated action of the connecting component 403, the mounting component 404, the locking component 405 and the adjusting component 407, the rotation and movement of the heating rod 406 are realized, thereby accurately controlling the heating position and heating range, effectively avoiding the problems of local overheating or uneven heating. At the same time, the cooperation between the spraying mechanism 2 and the heating mechanism can accurately control the cooling rate, optimize the microstructure of the forging, and enhance its strength and toughness. In addition, this device can adapt to large wind turbine flange forgings of different specifications and sizes, improve production efficiency and product quality, and has made significant improvements and enhancements compared with existing heat treatment methods.

[0053] In this application, conductive slip rings can be used to achieve electrical connection at any point where rotational power supply is required. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the scope of protection of this application.
