Description

Technical Field

[0001] The present invention relates to the technical field of wind power flange production, and particularly to an automatic forming device and method for offshore wind power flange production. Background Art

[0002] In the forming production of wind power flanges, it is usually necessary to first perform hot extrusion forging on steel pads and punch holes in the center, and then perform forming work through a ring rolling machine. However, in the existing production process, forging and forming are two separate processes, and during this process, it is also necessary to transport the flanges, which reduces the production rate. Moreover, due to the high-temperature characteristics of the raw materials during transportation, there are also certain risks.

[0003] Chinese Patent with application number 2023116713296 discloses a production device and method for a wind power main engine pitch flange. By directly placing the forging production device on one side of the ring rolling device, the overall floor area of the equipment is reduced. At the same time, by setting up a transfer component, the forged high-temperature workpieces are directly transported onto the ring rolling device, which is relatively convenient without the need for additional transfer.

[0004] Although the above device solves the safety problem during the transfer process by placing the production device in sequence with the ring rolling device and then transferring through the transfer component, there are certain requirements for the spatial layout of the site and the supporting use of the ring rolling machine, and there are certain limitations. Therefore, the present invention proposes an automatic forming device and method for offshore wind power flange production to solve the problems existing in the prior art. Summary of the Invention

[0018] The forming method using the above automatic forming device for offshore wind power flanges includes the following steps;

[0019] S1. Positioning of the blank. By placing the heated blank on the placement table, starting the first electric telescopic rod, the first electric telescopic rod pushes the support block, the rotating motor, the fixed block and the spray pipe to move up synchronously. At the same time, through the industrial camera, it is determined whether the height of the spray pipe reaches the requirement. When the height reaches, by starting the second electric telescopic rod, four groups of spray pipes are pushed to move synchronously, so as to perform central positioning on the blank. At the same time, the protective part protects the spray pipe to prevent direct contact between the spray pipe and the blank;

[0020] S2. Forging of the blank. After the blank is positioned, reset the spray pipe. By starting the fourth hydraulic cylinder, the fourth hydraulic cylinder pushes the mounting plate and the limiting plate to move down synchronously. At the same time, the forging seat and the central hole column are driven to move down synchronously through the sleeve, so as to extrude and forge the blank, and finally forge it into a disc shape;

[0021] S3. Piercing of the central hole. After forging, ensure the extrusion of the blank by the forging seat. At this time, by starting the fifth hydraulic cylinder, the cylindrical push block is pushed to move down, and then the central hole column is driven to move down, so as to perform extrusion punching on the central position of the blank;

[0022] S4. Ring rolling: After punching, reset the forging seat and the central hole column. At this time, start the first hydraulic cylinder to push the lifting seat to drive the punched billet to move upward, and move it to a position where the top of the lifting seat is flush with the bottom of the auxiliary roller. At this time, through the rotation assembly and the second hydraulic cylinder, drive the drive bin to move above the billet, and make the core roller insert into the central hole of the billet. Then, drive the billet to move towards the driving main roller through the second hydraulic cylinder, so that the outer wall of the billet fits with the outer wall of the driving main roller. At the same time, the auxiliary roller moves synchronously, so that the outer wall of the roller body of the auxiliary roller fits with the outer wall of the billet. At the same time, start the third hydraulic cylinder, and the third hydraulic cylinder pushes the taper roller set to move towards the billet synchronously, so that the outer wall of the taper roller set fits with the top wall and the bottom wall of the billet. Then, start the driving main roller to rotate, thereby driving the billet to rotate, so as to achieve the purpose of ring rolling;

[0023] S5. Spraying of coolant: Start the first electric telescopic rod, and the first electric telescopic rod pushes the support block, the rotating motor, the fixed block and the spray pipe to move upward synchronously. At the same time, determine whether the height of the spray pipe meets the requirements through the industrial camera. When the height reaches, start the second electric telescopic rod to push the four spray pipes to move synchronously. At the same time, cooperate with the rotating motor and the industrial camera to drive the spray pipes to face the roller body of the auxiliary roller and the core roller respectively. Then, pump the coolant in the coolant tank into and spray it out by the spray pipe through the delivery pipe and the hose.

[0024] The beneficial effects of the present invention are as follows: By installing the forging mechanism and the ring rolling mechanism inside the same housing at the same time, the forging and ring rolling are integrally designed. After forging, the ring rolling work can be directly carried out without further transportation, which is relatively convenient. At the same time, the positional relationship between the forging mechanism and the ring rolling mechanism is fully considered to ensure that the two work without conflict, reducing the intermediate transportation process, thereby increasing the forming rate of the billet. At the same time, the potential safety hazards during transportation are avoided. And the device is provided with a positioning mechanism, which can ensure the position of the billet on the placement table and ensure the forging effect of the forging mechanism. The device also has a partition chamber. One side of the partition chamber is a purging mechanism to ensure the purging and cleaning of the scale on the placement table, and the other side is a steam recovery mechanism to recycle and reuse the high-temperature gas after the evaporation of the coolant. With the setting of the collection tank, the use cost of the coolant is greatly reduced. At the same time, a rotating motor that can drive the spray pipe to rotate is also provided between the first electric telescopic rod and the fixed block of the device. After the coolant is transported by the transmission assembly, the spray pipe can carry out the spraying work of the coolant. Description of the Drawings

[0059] The forming method using the above automatic forming device for offshore wind power flange production includes the following steps;

[0060] S1. Positioning of the blank. By placing the heated blank on the placing table 4, starting the first electric telescopic rod 33, the first electric telescopic rod 33 pushes the support block 39, the rotating motor 40, the fixing block 34 and the nozzle pipe 37 to move upward synchronously. At the same time, the industrial camera 38 is used to determine whether the height of the nozzle pipe 37 reaches the requirement. When the height reaches, the second electric telescopic rod 35 is started to push the four groups of nozzle pipes 37 to move synchronously, so as to perform central positioning on the blank. At the same time, the protective part 59 protects the nozzle pipe 37 to prevent direct contact between the nozzle pipe 37 and the blank.

[0061] S2. Forging of the blank. After the blank is positioned, the nozzle pipe 37 is reset. By starting the fourth hydraulic cylinder 25, the fourth hydraulic cylinder 25 pushes the mounting plate 28 and the limiting plate 26 to move downward synchronously. At the same time, the forging seat 13 and the central hole column 14 are driven to move downward synchronously through the sleeve 29, so as to extrude and forge the blank, and finally forge it into a disc shape.

[0062] S3. Piercing of the central hole. After forging is completed, ensure the extrusion of the blank by the forging seat 13. At this time, start the fifth hydraulic cylinder 30 to push the cylindrical push block 31 downward, thereby driving the central hole column 14 downward, so as to extrude and punch the central position of the blank.

[0063] S4. Ring rolling. After punching, reset the forging seat 13 and the central hole column 14. At this time, start the first hydraulic cylinder 11 to push the lifting seat 10 to drive the punched blank to move upward, and move to the position where the top of the lifting seat 10 is flush with the bottom of the auxiliary roller 18. At this time, through the rotation assembly and the second hydraulic cylinder 19, drive the driving bin 20 to move above the blank, and make the core roller 21 able to insert into the central hole of the blank. Then, drive the blank to move towards the driving main roller 17 through the second hydraulic cylinder 19, so that the outer wall of the blank is attached to the outer wall of the driving main roller 17. At the same time, the auxiliary roller 18 moves synchronously, so that the outer wall of the roller body 51 of the auxiliary roller 18 is attached to the outer wall of the blank. At the same time, start the third hydraulic cylinder 24, and the third hydraulic cylinder 24 pushes the tapered roller set 23 to move towards the blank synchronously, so that the outer wall of the tapered roller set 23 is attached to the top and bottom walls of the blank. Then, start the driving main roller 17 to rotate, thereby driving the blank to rotate, so as to achieve the purpose of ring rolling.

[0064] S5. Spraying of the coolant. Start the first electric telescopic rod 33, and the first electric telescopic rod 33 pushes the support block 39, the rotating motor 40, the fixed block 34 and the spray pipe 37 to move upward synchronously. At the same time, determine whether the height of the spray pipe 37 reaches the requirement through the industrial camera 38. When the height reaches, start the second electric telescopic rod 35 to push the four spray pipes 37 to move synchronously. At the same time, cooperate with the rotating motor 40 and the industrial camera 38 to drive the spray pipes 37 to face the roller body 51 of the auxiliary roller 18 and the core roller 21 respectively. Then, pump the coolant in the coolant tank 6 into and spray it out by the spray pipes 37 through the delivery pipe 52 and the hose 53.
