Description

Technical Field

[0001] The present invention relates to the technical field of wind power flange processing, and more specifically, to an automatic rolling device for a wind power L-shaped flange and a use method thereof. Background Art

[0002] New energy wind power generation can improve the global energy shortage and environmental pollution problems. Common wind power generation equipment includes wind towers, and wind power flanges are often installed at the joints of wind towers. Generally, they are divided into T-type flanges and L-type flanges. The operating environment of wind turbines is harsh and the load is complex. The tower, as the main supporting component of the wind turbine, supports key components such as the hub assembly, generator, and base. Its safety is related to the safety of the entire machine operation. The tower is usually composed of multiple sections, and the sections are connected by flanges. In order to ensure that the tower has sufficient support strength, the flanges connected between the sections must meet the strength requirements.

[0003] Most of the flanges used in wind turbine towers are L-shaped, and the flange processing usually uses a ring rolling machine to expand the flange hole. The ring rolling machine consists of an active roller, a driven roller, a guide roller, a control roller and other drive structures. When working, the heated flange ring blank will be put on the outside of the driven roller, and the motor will only drive the active roller to rotate, so that the active roller rotates with the ring blank. At the same time, the outer side of the active roller is radially fed by oil pressure, so that the outer side of the blank is compressed and lengthened. The guide roller will always lean against the outside of the ring blank, and the remaining rollers rotate by the friction of the ring blank.

[0004] For example, a ring rolling machine for flange production and processing with publication number CN115318995B has interlocking rollers arranged on the inner and outer sides of the ring material through a fixed plate. During the subsequent rotation of the ring material, the scraper will press against the inner and outer sides of the ring material and scrape to scrape off the oxide layer attached to the inner and outer sides of the ring material. Before the ring material is rotated and rolled, the oxide layer on the inner and outer surfaces of the ring material is removed, ensuring that there is no interference from the oxide layer during the rolling process of the ring material.

[0005] However, the equipment has defects during use. First, the device is placed vertically, and for the ring rolling machine, the blank needs to be heated at high temperature during processing. The vertical placement makes the loading process difficult. Even if a lifting device is used, there is still a risk of falling, which is prone to production accidents and has poor safety. Second, the device is limited to fixing the blank's outer ring surface for auxiliary positioning during the processing, and there is no fixation on the upper end surface of the blank, which causes the blank to be easily displaced in height during the ring rolling process. Even if a thickness ring rolling mechanism is used, this situation will still occur, resulting in a decrease in the processing quality of the blank. In addition, the auxiliary positioning mechanisms on the market need to be opened one by one, which makes the operation cumbersome, and automatic positioning cannot be achieved, resulting in low efficiency.

A first mounting inclined plate 211 is also mounted on the side of the mounting seat 257 close to the second telescopic cylinder 256, and a third telescopic cylinder 212 is mounted on the first mounting inclined plate 211. A second mounting inclined plate 217 is also connected to the lower end of one end of the pressing frame 215 close to the rotating shaft 214, and the end of the third telescopic cylinder 212 is rotatably connected to the second mounting inclined plate 217.

[0024] This embodiment is implemented as follows: before use, the core roller mechanism 25 will be recovered to the inside of the recovery port 252 through the first telescopic cylinder 254 inside the extension seat 253, and at this time the core roller mechanism 25 is not connected to the linkage mechanism 22. When the blank 4 is fed to the top of the core roller mechanism 25, the first telescopic cylinder 254 pushes out the core roller seat 255 in the core roller mechanism 25, and the second connecting plate 226 is connected to the splicing hole inside the first connecting plate 225 through the splicing column 230, so as to achieve connection with the linkage mechanism 22.

The work of the pressing mechanism 21 is independent, and the third telescopic cylinder 212 needs to be controlled to work, and the second mounting inclined plate 217 is pushed, so that the pressing frame 215 is rotated by the rotating shaft 214.

At the same time, the fixing ring 216 itself can rotate to ensure that when the blank 4 rotates, it can follow the rotation, and ensure that the fixing ring 216 does not affect the rotation of the blank 4. The driving mechanism 23 is driven by the driving reducer 232 to drive the driving roller 231 to rotate, thereby rotating the blank 4, and cooperates with the main core roller 251 to achieve rolling of the blank 4.

A plurality of pushing cylinders 503 are also installed on the side of the receiving plate 501 away from the feeding assembly 3, and a pushing connecting rod 504 is connected between the ends of the plurality of pushing cylinders 503. The pushing connecting rod 504 is arranged parallel to the side of the receiving plate 501, and the two ends of the pushing connecting rod 504 are also connected to the material rack rods 505, and the material rack rods 505 are slidably arranged on both sides of the receiving plate 501.

[0030] In actual application, when there is no blank 4 on the conveying roller 34, the guard plate 32 should be below both sides of the conveying roller 34. When loading, after the blank 4 falls to the conveying roller 34, the gravity telescopic mechanism 33 works to push out the guard plates 32 on both sides, thereby shielding both sides of the conveying seat and preventing the blank 4 from falling. The specific implementation method is that the conveying frame 35 is pressed down by the gravity of the blank 4 itself. During the pressing process of the conveying frame 35, the connecting seat 331 inside the gravity telescopic mechanism 33 is pressed down, and at the same time, the connecting seat 331 presses down the pressing frames 339 on both sides, and the pressing frames 339 move downward inside the first support frame 340 and the second support frame 341 through rollers. At this time, the tilting rod 345 presses down one end of the main lever 336, and the main lever 336 rotates along the support rod 338, and the other end of the main lever 336 lifts the first sliding rod 334, and the first sliding rod 334 drives the lifting seat 335 to lift. During the lifting process of the lifting seat 335, the extension plate 36 is ejected, and the guard plate 32 is connected to the extension plate 36, so that the guard plate 32 is automatically ejected.

[0031] It should be noted that when not feeding, the height of the conveying frame 35 and the conveying roller 34 should be higher than the height of the frame 1 to prevent the height of the conveying frame 35 and the conveying roller 34 from being lower than the height of the frame 1 during feeding, thereby blocking the feeding; The purpose of the pushing assembly 5 is to completely feed the blank 4 into the core roller mechanism 25. Before the blank 4 enters the frame 1, it will contact the pushing assembly 5. The pushing assembly 5 is pushed, and after the receiving plate 501 contacts, it will rotate at a right angle in the frame 1. When the blank 4 completely falls on the receiving plate 501, the receiving plate 501 turns to a horizontal state, and at this time, the two ends of the blank 4 will be pressed on the rack rod 505. At this time, the pushing connecting rod 504 is pushed by the fourth telescopic cylinder 502, and the pushing connecting rod pushes out the rack rods 505 on both sides and feeds the blank 4 to the core roller mechanism 25 to realize loading, and the pushing assembly 5 is recovered after the blank 4 is detached.

[0032] See also Figure 1 - Fig.10 The present invention provides a method for using an automatic rolling device for a wind power L-shaped flange, the method comprising the following steps: Step 1: When in use, first place the blank 4 on the feeding assembly 3, the feeding assembly 3 transports the blank 4 into the frame 1, and contacts the pushing assembly 5, the pushing assembly 5 is pushed, and rotates at a right angle in the frame 1, and after turning to a horizontal state, the blank 4 is pushed into the core roller mechanism 25 by the pushing assembly 5, and the pushing assembly 5 is recovered after the blank 4 is separated, and the core roller mechanism 25 is in a falling recovery state; Step 2: Subsequently, the core roller mechanism 25 works to extend from the inside of the extension seat 253 and is inserted into the blank 4, thereby realizing automatic loading of the blank 4. In addition, during the rising process of the core roller mechanism 25, the splicing column 230 is connected to the splicing hole, thereby realizing automatic connection between the core roller mechanism 25 and the linkage mechanism 22. Subsequently, the linkage mechanism 22 works to displace the blank 4 and the core roller mechanism 25 and bring them closer to the driving mechanism 23. Step 3: Then, in the process of approaching, the upper end of the linkage mechanism 22 automatically approaches and fits the outer annular surface of the blank 4 to assist in positioning the blank 4. At the same time, the upper end of the linkage mechanism 22 can be connected to the core roller mechanism 25 to assist in positioning the upper part of the blank 4. Then, the thickness rolling mechanism 24 is pushed to contact the upper and lower surfaces of the blank 4. Step 4: Finally, the driving mechanism 23 is rotated to automatically roll the blank 4.

[0033] In summary, the present invention is provided with a frame 1, a pressing mechanism 21, a linkage mechanism 22, a core roller mechanism 25, a pushing assembly 5 and a feeding assembly 3. First, the feeding assembly 3 is used in conjunction with the pushing assembly 5, and the feeding assembly 3 conveys the blank 4. During the conveying process, the blank 4 will automatically lift the guard plates 32 on both sides of the feeding assembly 3, thereby reducing the problem that the fixed guard plates 32 cause the blank 4 to be lifted higher during the loading process, and reducing the falling of the blank 4 during the feeding process; at the same time, the pushing assembly 5 will After receiving the blank 4, it is automatically dumped and fed, and the blank 4 is sent to the core roller mechanism 25, and the core roller mechanism 25 extends out to realize the loading and is connected to the linkage mechanism 22 at the same time. The linkage mechanism 22 can bring the core roller mechanism 25 and the blank 4 closer to the driving mechanism 23. During the approaching process, the automatic movement of the linkage mechanism 22 is realized to assist in positioning the outer ring surface of the blank 4; and the pressing mechanism 21 can assist in fixing the upper end surface of the blank 4, reduce the up and down deviation of the blank 4, and improve the processing quality and efficiency.
