However, a wind power flange is a structural member that connects each section of a tower barrel or connects the tower barrel and a hub, and between the hub and the blades. Usually, bolt connection is also adopted. Briefly speaking, a wind power flange is a flange of a wind power generator set. A wind power flange is also called a wind tower flange, and its technological process mainly includes the following steps: the raw material adopts refined plates, the raw material is re-inspected after entering the factory, the blanking is carried out by a large sawing machine, the raw material enters a heating furnace for heating, the top punching is repeatedly forged into shape, and then it undergoes multiple heat treatments such as normalizing, quenching, annealing, and tempering, followed by rough machining, and then fine machining after passing the inspection.

[0003] However, during the quenching process, the wind power flange will generate internal stress due to uneven thermal expansion and contraction inside the workpiece, resulting in deformation of the workpiece.

[0009] Further improvement lies in that: the side anti-deformation mechanism includes an installation chamber, a bidirectional screw rod, a second motor, an adjusting rod and a fixing column.

A second motor for driving the bidirectional screw rod to rotate is provided on the side wall of the installation chamber.

[0010] Further improvement lies in that: infusion pipes are provided at both ends of the driving chamber and at the central position of the connection end between the liquid storage tank and the driving chamber.

A third motor is fixed on the outer wall of the outer housing, and the output end of the third motor is fixedly connected to the second gear.

[0015] The treatment method using the above heat treatment device for preventing flange deformation of a wind power tower includes the following steps;

[0016] S1. Placement of the flange workpiece. First, start the lifting cylinder to separate the upper furnace body and the lower furnace body. Then, adjust the surface anti-deformation mechanism and the side anti-deformation mechanism according to the diameter and width of the flange. Finally, place the flange workpiece on the surface anti-deformation mechanism of the lower furnace body.

[0017] S2. Adjustment of the surface anti-deformation mechanism. According to the parameter of the flange diameter, start the first motor. The first motor drives the first gear to rotate. At the same time, through the meshing of the first toothed ring and the first gear, the rotating tube is driven to rotate, and then the adjusting disc is driven to rotate. Through the spiral adaptation between the adjusting disc and the adjusting seat, the position of the adjusting seat is adjusted, so as to meet the requirement of supporting flanges with different diameters.

[0018] S3. Adjustment of the side anti-deformation mechanism. According to the parameter of the flange width, start the second motor. The second motor drives the bidirectional screw to rotate, and then drives the fixed column to move through the connecting rod, so as to adjust the distance between the two groups of fixed columns, so that they can be stuck on the inner and outer sides of the flange workpiece when moving down.

[0019] S4. Sealing of the furnace body; start the lifting cylinder to close the upper furnace body and the lower furnace body. At this time, the limiting roller on the upper furnace body moves down and fits with the top surface of the flange workpiece. At the same time, for flange workpieces with different thicknesses, when closing, through the contraction of the supporting spring, the limiting roller fits with the top surface of the flange workpiece. At the same time, the depth of the sealing ring at the bottom of the upper furnace body when inserted into the sealing groove also changes accordingly.

[0020] S5. Quenching of the flange workpiece. After the furnace body is sealed, the quenching oil in the liquid storage tank on the upper furnace body is pumped into the lower furnace body through the connecting pipe by the water pump. When the quenching oil covers the flange workpiece, the third motor is started to drive the second gear to rotate, thereby driving the second gear ring to rotate, and further driving the limit rollers and the fixed columns on the driving chamber to rotate, so as to form limits on the top surface, bottom surface, outer side surface and inner side surface of the flange workpiece, thus preventing the flange from deforming. At the same time, the rotation of the limit rollers and the fixed columns stirs the quenching oil, making the temperature of the quenching oil more uniform. Meanwhile, through the operation of the water pump, the quenching oil forms an internal circulation, further increasing the uniformity of the heat received by the flange workpiece, and further preventing the flange workpiece from deforming.

[0021] S6. Recycling of the quenching liquid. Driven by the water pump in the liquid storage tank of the lower furnace body, the quenching oil in the liquid storage tank of the lower furnace body is transported to the liquid storage tank of the upper furnace body. At this time, the quenching oil is continuously fed into the liquid storage tank of the lower furnace body through the delivery pipe on the lower furnace body. When the quenching oil is completely recycled, the water pump of the lower furnace body is turned off. At this time, the upper and lower furnace bodies are separated, and the workpiece is taken out.

[0022] The beneficial effects of the present invention are as follows: Through the spiral adaptation between the adjusting disc and the adjusting seat, the rotation of the adjusting disc drives the three groups of adjusting seats to move synchronously, so as to support and limit flange workpieces with different diameters. The driving force provided by the synchronous rotation assembly can drive the synchronous rotation of the limit rollers and the fixed columns, thus forming limit surfaces on the top surface, bottom surface, outer wall and inner wall of the flange workpiece, restricting the shape change of the flange workpiece, preventing the workpiece from deforming. At the same time, in combination with the use of quenching oil and the stirring force generated when the limit rollers and the fixed columns rotate, the temperature of the quenching oil is more uniform during cooling, thus preventing the flange workpiece from being unevenly heated and further preventing the flange workpiece from deforming.

Then, adjust the surface anti-deformation mechanism and the side anti-deformation mechanism according to the diameter and width of the flange. Finally, place the flange workpiece on the surface anti-deformation mechanism of the lower furnace body 3.

[0046] S2. Adjustment of the surface anti-deformation mechanism. According to the parameter of the flange diameter, start the first motor 17. The first motor 17 drives the first gear 19 to rotate. At the same time, through the meshing of the first toothed ring 18 and the first gear 19, the rotating pipe 20 is driven to rotate, and then the adjusting disk 21 is driven to rotate.

[0050] S6. Recycling of the quenching liquid. Through the driving force provided by the water pump 32 in the liquid storage tank 6 of the lower furnace body 3, the quenching oil in the liquid storage tank 6 of the lower furnace body 3 is transported to the liquid storage tank 6 of the upper furnace body 2.

A heat treatment device for preventing flange deformation of a wind power tower, according to claim 1, characterized in that: The rotating assembly includes a second toothed ring (38), a second gear (39) and a third motor (40). A second toothed ring (38) is fixed on the outer wall of the liquid storage tank (6). A second gear (39) is meshed with one side of the second toothed ring (38), and the second gear (39) is meshed with the second toothed ring (38). A third motor (40) is fixed on the outer wall of the outer casing (5), and the output end of the third motor (40) is fixedly connected to the second gear (39).

9. A processing method of a heat treatment device for preventing flange deformation of a wind power tower according to any one of claims 1-8, characterized in that: It includes the following steps; S1. Placement of the flange workpiece. First, start the lifting cylinder (33) to separate the upper furnace body (2) from the lower furnace body (3). Then, adjust the surface anti-deformation mechanism and the side anti-deformation mechanism according to the diameter and width of the flange. Finally, place the flange workpiece on the surface anti-deformation mechanism of the lower furnace body (3). S2. Adjustment of the surface anti-deformation mechanism. According to the parameter of the flange diameter, start the first motor (17). The first motor (17) drives the first gear (19) to rotate. At the same time, through the meshing of the first toothed ring (18) and the first gear (19), the rotating pipe (20) is driven to rotate, and then the adjusting disk (21) is driven to rotate. Through the spiral adaptation between the adjusting disk (21) and the adjusting seat (22), the position of the adjusting seat (22) is adjusted, so as to meet the requirement of supporting flanges with different diameters; S3. Adjustment of the side anti-deformation mechanism. According to the parameter of the flange width, start the second motor (25). The second motor (25) drives the bidirectional screw rod (24) to rotate, so as to drive the fixed column (27) to move through the connecting rod, and then adjust the distance between the two groups of fixed columns (27) so that they can be stuck on the inner and outer sides of the flange workpiece when moving down; S4. Sealing of the furnace body; Close the upper furnace body (2) and the lower furnace body (3) by starting the lifting cylinder (33). At this time, the limit roller (10) on the upper furnace body (2) moves down and fits with the top surface of the flange workpiece. At the same time, for flange workpieces with different thicknesses, when closing, through the contraction of the support spring (11), the limit roller (10) fits with the top surface of the flange workpiece. At the same time, the depth of the sealing ring (36) at the bottom of the upper furnace body (2) when inserted into the sealing groove (37) also changes accordingly; S5. Quenching of the flange workpiece. After the furnace body is sealed, pump the quenching oil in the liquid storage tank (6) on the upper furnace body (2) into the lower furnace body (3) through the connecting pipe by the water pump (32). When the quenching oil covers the flange workpiece, start the third motor (40) to drive the second gear (39) to rotate, so as to drive the second toothed ring (38) to rotate, and then drive the limit roller (10) and the fixed column (27) on the drive bin (7) to rotate, so as to form a limit on the top surface, bottom surface, outer side and inner side of the flange workpiece, thus preventing the flange from deforming. At the same time, the rotation of the limit roller (10) and the fixed column (27) stirs the quenching oil, so that the temperature of the quenching oil is more uniform. At the same time, through the operation of the water pump (32), the quenching oil forms an internal circulation, further increasing the uniformity of the heat received by the flange workpiece, and further preventing the flange workpiece from deforming; S6. Recycling of the quenching liquid. Through the driving force provided by the water pump (32) in the liquid storage tank (6) of the lower furnace body (3), the quenching oil in the liquid storage tank (6) of the lower furnace body (3) is transported to the liquid storage tank (6) of the upper furnace body (2). At this time, the quenching oil is continuously fed into the liquid storage tank (6) of the lower furnace body (3) through the liquid delivery pipe (29) on the lower furnace body (3). When the quenching oil is completely recycled, the water pump (32) of the lower furnace body (3) is closed. At this time, separate the upper and lower furnace bodies (3) and take out the workpiece.
