[0014] A method for using an intelligent down-pressing L-shaped device for wind power generation tower flanges, the specific steps of which are as follows:
[0015] The first step involves rolling the wind turbine tower flange body blank into a ring. First, a multi-section cylinder raises the top box, which in turn raises the center roller. Then, baffle three is opened to place the wind turbine tower flange body blank onto the processing table. Baffle three is then closed, and motor three is started. Motor three drives the drive shaft to rotate, which in turn drives the drive roller to rotate. The rotation of the drive roller causes the wind turbine tower flange body blank to rotate on the processing table. Simultaneously, the start of motor three causes bevel gear three to rotate, which in turn drives bevel gear four to rotate. The rotation of bevel gear four drives shaft six to rotate, thus connecting sprocket one and chain one. The side rollers begin to rotate, and simultaneously, the multi-section telescopic cylinder is activated to shorten the center roller, causing it to move downwards. At this point, the center roller and side rollers work together to flatten the left side of the wind turbine tower flange body blank. Then, motor four is activated to drive the upper rolling roller to rotate. Simultaneously, under the action of two gears, the lower rolling roller begins to rotate in the opposite direction, further flattening the right side of the wind turbine tower flange body blank. As the rolling ring continues to work, the diameter of the wind turbine tower flange body blank increases. At this point, the cylinder is activated to move the two rolling rollers to the right to accommodate the increased diameter of the wind turbine tower flange body blank.
[0016] The second step involves pressing down the blank of the wind turbine tower flange body. When the rolling of the blank is completed, motor one is started. Motor one drives bevel gear one to rotate, which in turn drives bevel gear two to rotate, which in turn drives shaft one to rotate. Shaft one drives gear one to rotate, which in turn drives gear one to rotate. Under the action of gear ring one, gear one revolves around gear ring one while rotating on its own axis. The rotation of gear one, under the action of shaft three, connecting block two, and shaft four, drives connecting block three to move vertically up and down, which in turn drives the lower pressure plate to move up and down under the action of the limit block and the groove, thus pressing down and hammering the blank of the wind turbine tower flange body. During the pressing down process of the lower pressure plate, motor two is started, which drives the electric telescopic column to rotate, so that the upper end of baffle one moves into the cavity two. At the same time, the rolling wheel rotates out of the lower pressure plate to flatten the inner wall of the blank of the wind turbine tower flange body, thus producing the L-shaped wind turbine tower flange body.
[0017] The third step involves spraying the wind turbine tower flange body during production. The pump on the outer wall of water pipe one is started to draw water out of the water tank and spray it out through the spray head at the lower end of water pipe two. At the same time as the water in the water tank is drawn out, the start of motor one drives the output shafts at both ends of motor one to rotate. The rotation of the upper output shaft of motor one, under the action of sprocket two and chain two, causes shaft seven to start rotating, which in turn causes two gears three to start rotating. The rotation of gear three drives gear ring two to rotate, which in turn drives water pipe two to rotate, increasing the spraying area and thus completing the spraying work on the wind turbine tower flange body blank.
[0018] The fourth step is wastewater recovery. As the spraying of the wind turbine tower flange blank proceeds, the wastewater flows into the recovery chamber through opening two. Simultaneously, some wastewater enters opening two and is pumped into the recovery chamber through water pipe three. After being filtered by the filter plate, the wastewater can be pumped into the water tank for reuse. With the filtration of wastewater and the start of motor three, the rotating shaft eight begins to rotate under the action of sprocket three and chain three. The rotation of rotating shaft eight drives the rotating plate to rotate, which in turn drives the limiting post to rotate with the rotating plate. The rotation of the limiting post causes the slider to move up and down under the action of the limiting groove, which in turn causes protrusion one to collide with protrusion two, causing the filter plate to vibrate, thus preventing the filter plate from clogging.
[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:
[0020] This invention, through the setting of a pressing unit, eliminates the need for existing L-shaped flange production methods that require drilling holes in the high-temperature forged steel ingots using a forging hydraulic press to create a through hole in the center of the disc-shaped ingot, followed by ring rolling to obtain the desired annular workpiece. This invention completes drilling, ring rolling, and L-shaped wind turbine tower flange production in a single unit. The simplified production method, coupled with full automation, significantly reduces the labor intensity of workers, thereby increasing the efficiency of wind turbine tower flange production. The multi-directional cooperation of the center roller, side rollers, rolling wheels, and pressing rollers greatly increases the efficiency of wind turbine flange production. The ease and flatness of the ring rolling process for the wind turbine tower flange body increases the quality of the wind turbine tower flange body production. Furthermore, the cleaning unit allows for spraying the wind turbine tower flange body via a spray system, achieving a cooling effect. After the ring rolling process, the cooling of the wind turbine tower flange body is accelerated. Compared to the existing manual spraying method using handheld water hoses, the spraying operation significantly reduces the danger to workers, facilitating the deployment of the equipment. Simultaneously, the recycling mechanism allows for the recovery and reuse of the sprayed wastewater, preventing water waste. Attached Figure Description

[0046] A method for using an intelligent down-pressing L-shaped device for wind power generation tower flanges, the specific steps of which are as follows:
[0047] The first step involves rolling the wind turbine tower flange body 5 blank into a ring.

Chain 34 causes the side roller 7 to start rotating, and simultaneously, the multi-section telescopic cylinder 2 is activated to shorten, causing the center roller 6 to move downwards. At this time, the center roller 6 and the side roller 7 cooperate to flatten the left side of the wind turbine tower flange body 5 blank. Then, motor 4 is activated to drive the upper rolling roller 41 to rotate. At this time, under the action of two gears 40, the lower rolling roller 41 starts to rotate in the opposite direction, thereby flattening the right side of the wind turbine tower flange body 5 blank. As the rolling ring works, the diameter of the wind turbine tower flange body 5 blank becomes larger and larger. At this time, cylinder 38 is activated to drive the two rolling rollers 41 to move to the right to adapt to the diameter of the wind turbine tower flange body 5 blank.
[0048] The second step involves pressing down the blank of the wind turbine tower flange body 5. Once the ring rolling of the blank is complete, motor 8 is started. Motor 8 drives bevel gear 14 to rotate, which in turn drives bevel gear 15, which in turn drives shaft 16 to rotate. Shaft 16 then drives gear 19 to rotate, causing gear 19 to revolve around gear ring 20 while simultaneously rotating on its own axis. The rotation of gear 19 is influenced by shaft 21, connecting block 22, and shaft 4. Under the action of 23, the connecting block 3 24 moves vertically up and down, which in turn drives the lower pressure plate 11 to move up and down under the action of the limiting block 10 and the groove 9, thereby pressing and hammering the blank of the wind power generation tower flange body 5. During the pressing process of the lower pressure plate 11, the motor 25 is started, which drives the electric telescopic column 26 to rotate, so that the upper end of the baffle 1 28 moves towards the inside of the cavity 29. At the same time, the rolling wheel 13 rotates out of the lower pressure plate 11 to flatten the inner wall of the blank of the wind power generation tower flange body 5, thereby producing the L-shaped wind power generation tower flange body 5.
[0049] The third step involves spraying the wind turbine tower flange body 5 during production. The pump on the outer wall of water pipe 44 is started to draw water out of water tank 43 and spray it out through the spray head at the lower end of water pipe 45. At the same time as the water in water tank 43 is drawn out, the start of motor 8 drives the output shafts at both ends of motor 8 to rotate. The rotation of the upper output shaft of motor 8, under the action of sprocket 2 and chain 2 49, causes shaft 7 48 to start rotating, which in turn causes two gears 3 47 to start rotating. The rotation of gears 3 47 drives gear ring 2 46 to rotate, which in turn drives water pipe 2 45 to rotate, increasing the spray area and thus completing the spraying work on the blank of wind turbine tower flange body 5.
[0050] The fourth step is wastewater recycling. As the spraying of the wind turbine tower flange body 5 blank is carried out, the wastewater flows into the recycling chamber 50 through the second opening 59. At the same time, some wastewater enters the second opening 59 and is pumped into the recycling chamber 50 through the third water pipe 64. After being filtered by the filter plate 51, the wastewater can be pumped into the water tank 43 for reuse. With the filtration of wastewater and the start of the third motor 31, the shaft 8 52 starts to rotate under the action of the sprocket 3 and the chain 3 61. The rotation of the shaft 8 52 drives the rotating plate 53 to rotate, which in turn drives the limiting post 54 to rotate with the rotating plate 53. The rotation of the limiting post 54 causes the slider 55 to move up and down under the action of the limiting groove 56, which in turn causes the first protrusion 57 to hit the second protrusion 58, causing the filter plate 51 to vibrate, which can prevent the filter plate 51 from clogging.

10. The method of using the intelligent down-pressing L-shaped device for wind power tower flanges according to any one of claims 1-9, characterized in that: The specific steps are as follows: The first step is to roll the blank of the wind power tower flange body (5). First, the top box (3) is raised by the multi-section cylinder (38), which in turn drives the center roller (6) to rise. Then, the baffle three (63) is opened to place the blank of the wind power tower flange body (5) on the processing table (4). Then the baffle three (63) is closed. Then the motor three (31) is started. The start of the motor three (31) drives the drive shaft (35) to rotate, which in turn drives the active roller (36) to start rotating. The rotation of the active roller (36) causes the blank of the wind power tower flange body (5) to start rotating on the processing table (4). At the same time, the start of the motor three (31) causes the bevel gear three (32) to rotate, which in turn drives the bevel gear four to start rotating. The rotation of the bevel gear four drives the rotating shaft six (33) to start rotating, thereby passing through The sprocket and chain (34) cause the side roller (7) to start rotating. At the same time, the multi-section telescopic cylinder (2) is activated to shorten, causing the center roller (6) to start moving downward. At this time, the center roller (6) and the side roller (7) cooperate to flatten the left side of the wind power tower flange body (5) blank. Then, the motor four is activated to drive the upper rolling roller (41) to rotate. At this time, under the action of the two gears (40), the lower rolling roller (41) is driven to start rotating in the opposite direction, thereby flattening the position of the wind power tower flange body (5) blank on the right side of the device. As the rolling ring works, the diameter of the wind power tower flange body (5) blank becomes larger and larger. At this time, the cylinder (38) is activated to drive the two rolling rollers (41) to move to the right to adapt to the diameter of the wind power tower flange body (5) blank. The second step is to press down the blank of the wind power tower flange body (5). When the rolling of the blank of the wind power tower flange body (5) is completed, start motor one (8). Motor one (8) starts to drive bevel gear one (14) to rotate. The rotation of bevel gear one (14) drives bevel gear two (15) to rotate, which in turn drives shaft one (16) to rotate. The rotation of shaft one (16) drives gear one (19) to start to rotate. Thus, under the action of gear ring one (20), gear one (19) revolves around gear ring one (20) while rotating on its own axis. The rotation of gear one (19) is caused by the rotation of shaft three (21), connecting block two (22) and shaft. Under the action of the fourth (23), the connecting block three (24) moves vertically up and down, which in turn drives the lower pressure plate (11) to move up and down under the action of the limiting block (10) and the groove (9), thereby pressing and hammering the blank of the wind power generation tower flange body (5). During the pressing process of the lower pressure plate (11), the second motor (25) is started, which drives the electric telescopic column (26) to rotate, so that the upper end of the baffle one (28) moves towards the inside of the cavity two (29). At the same time, the rolling wheel (13) rotates out of the lower pressure plate (11) and flattens the inner wall of the blank of the wind power generation tower flange body (5), thereby producing the L-shaped wind power generation tower flange body (5). The third step is to spray the wind power tower flange body (5) while it is being produced. The pump on the outer wall of the water pipe (44) is started to pump out the water in the water tank (43) and then spray it out through the spray head at the lower end of the water pipe (45). At the same time as the water in the water tank (43) is pumped out, the output shafts at the upper and lower ends of the motor (8) are driven to rotate as the motor (8) is started. The rotation of the upper output shaft of the motor (8) is caused by the action of the sprocket and the chain (49) to make the rotating shaft (48) start to rotate, and then the two gears (47) start to rotate. The rotation of the gears (47) drives the gear ring (46) to rotate, and then drives the water pipe (45) to rotate, increasing the spray area, thereby completing the spraying work on the blank of the wind power tower flange body (5). The fourth step is wastewater recycling. As the spraying work on the blank of the wind power tower flange body (5) is carried out, the wastewater flows into the recycling chamber (50) through the second opening (59). At the same time, some wastewater enters the second opening (59) and is pumped into the recycling chamber (50) through the third water pipe (64). After being filtered by the filter plate (51), the wastewater is pumped into the water tank (43) for reuse. With the filtration of wastewater and the start of the third motor (31), the shaft eight (52) starts to rotate under the action of the third sprocket and the third chain (61). The rotation of the shaft eight (52) drives the rotating plate (53) to rotate, which in turn drives the limiting column (54) to rotate with the rotating plate (53). The rotation of the limiting column (54) causes the slider (55) to move up and down under the action of the limiting groove (56), which in turn drives the first protrusion (57) to hit the second protrusion (58), causing the filter plate (51) to vibrate, thus preventing the filter plate (51) from being blocked.
