Description

Technical Field

[0001] This invention relates to the field of punching technology, and more particularly to a punching equipment for wind turbine flange processing. Background Technology

[0002] In the field of wind power equipment manufacturing, wind turbine flanges, as fundamental components connecting key parts such as towers and hubs, play a decisive role in the stability and safety of wind turbine generator sets due to their processing quality. However, existing wind turbine flange punching equipment faces many problems that urgently need to be solved in practical applications.

[0003] First, traditional equipment lacks an effective clamping and calibration mechanism when positioning wind turbine flanges, often relying on manual adjustment, which is not only inefficient but also makes it difficult to ensure accurate positioning of the flange during processing, easily leading to hole position deviations and increased scrap rate.

[0004] Secondly, traditional punching equipment has poor versatility. Its punching heads are usually of fixed specifications and cannot be flexibly changed according to different punching needs, making it difficult to meet diverse processing requirements. When it is necessary to process holes of different sizes and shapes, it is often necessary to replace the entire set of equipment, which increases the equipment purchase cost and production preparation time, and reduces production efficiency.

[0005] Furthermore, traditional equipment cannot achieve precise rotation and secondary positioning of wind turbine flanges during continuous processing. After completing the processing of one hole, it is difficult to guarantee the accuracy of the rotation angle when rotating the flange to process the next hole. Moreover, the lack of a secondary positioning calibration mechanism makes it difficult to control the positional accuracy between subsequent holes and already processed holes, which seriously affects the overall quality of wind turbine flanges. This defect of traditional equipment is particularly prominent when processing wind turbine flanges with high precision requirements, and it cannot meet the high precision requirements of modern wind power generation equipment for components.

[0006] In conclusion, developing a wind turbine flange processing punching equipment capable of precise positioning, flexible component replacement, and accurate rotation and secondary positioning calibration during continuous processing has become an urgent need to improve the processing quality and production efficiency of wind turbine flanges and promote the development of the wind power industry.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

The fixing unit can accurately fix the hydraulic cylinder in a suitable position on one side of the mounting frame, ensuring the stability of the equipment during the punching process and effectively avoiding the problem of affecting the punching accuracy due to equipment instability. At the same time, the clamping unit and the stop unit work together to firmly clamp the wind turbine flange between them. Compared with the traditional equipment that relies on manual adjustment of positioning, this greatly improves the accuracy and efficiency of positioning. In addition, before punching, the positioning unit will first enter the punched hole for calibration and positioning, and then the punching head will perform the punching operation. This innovative design can accurately control the hole position, effectively reduce the scrap rate, and avoid the waste of production costs caused by inaccurate positioning. The advantages are even more obvious when processing large wind turbine flanges.

[0025] The punching head of this equipment can be flexibly replaced according to punching needs, effectively solving the problem of poor versatility of traditional punching equipment. Regardless of the size or shape of the holes being processed, there is no need to replace the entire equipment; only the corresponding punching head needs to be changed to meet diverse processing requirements. This flexible component replacement capability not only reduces equipment purchase costs but also significantly shortens production preparation time and substantially improves production efficiency, better adapting to the diverse needs of modern wind power equipment manufacturing for component processing.

[0026] During continuous processing, the equipment's rotating unit drives the wind turbine flange to rotate precisely between the positioning unit and the clamping unit. The rotation angle can be accurately controlled according to processing requirements. Furthermore, before the secondary stamping, the positioning unit performs calibration and positioning, ensuring the positional accuracy between subsequent holes and already processed holes. This precise and controllable continuous processing capability effectively solves the quality problems caused by the inability of traditional equipment to achieve precise rotation and secondary positioning when processing high-precision wind turbine flanges. It meets the stringent high-precision requirements of modern wind power equipment for components, greatly improving the overall processing quality of wind turbine flanges.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] like Figures 1-10As shown, an embodiment of the present invention provides a punching device for processing wind turbine flanges, including a workbench 101. A mounting bracket 102 is fixedly installed on the upper surface of the workbench 101. A hydraulic cylinder 103 is provided on one side of the mounting bracket 102, and a punching rod 104 is fixedly installed on the telescopic end of the hydraulic cylinder 103. A punching head 105 is sleeved on the end of the punching rod 104, and the punching head 105 and the punching rod 104 are fixed by a pin. A fixing opening 106 is opened on the upper surface of the workbench 101, and symmetrically distributed movable openings 107 are also opened on the upper surface of the workbench 101. The device also includes a fixing unit, which is disposed in... The mounting bracket 102 includes: a stop unit, located below the workbench 101, used to block the wind turbine flange when it is placed on the surface of the workbench 101; a clamping unit, located below the workbench 101, used to clamp the wind turbine flange between the stop unit and the clamping unit; a rotating unit, located on the upper surface of the workbench 101, used to rotate the wind turbine flange between the stop unit and the clamping unit; and a positioning unit, located in the mounting bracket 102, used to calibrate and position the wind turbine flange after it has rotated.

[0040] Before punching, the hydraulic cylinder 103 can be fixed to a suitable position on one side of the mounting bracket 102 using the fixing unit. The punching head 105 at the bottom of the punching rod 104 can be flexibly replaced according to punching needs. After the equipment is debugged, the wind turbine flange to be punched can be placed on the workbench 101. The stop unit can block one side of the wind turbine flange, and the clamping unit clamps the wind turbine flange between the stop unit and the clamping unit. Then, the hydraulic cylinder 103 can drive the punching rod 104 downwards, which in turn drives the punching head 105 downwards and through the wind turbine flange, thus achieving the punching operation. The waste generated during punching can be... The flange is directly lowered through the fixed port 106. After the processing of a single hole is completed, the rotating unit drives the wind turbine flange to rotate between the stop unit and the clamping unit. This allows the wind turbine flange to rotate at a certain angle according to the processing requirements. Then, it is punched again through the punching head 105. This process is repeated to complete the punching process of the wind turbine flange. After the wind turbine flange rotates and before the secondary punching occurs, when the punching rod 104 moves down, it will first cause the positioning unit to enter the punched hole that has just been punched. Then, the punching head 105 will penetrate the wind turbine flange to punch. This effectively realizes the calibration and positioning of the wind turbine flange before punching, which can greatly improve the accuracy of the punching process and achieve better results.

[0041] As one embodiment of the present invention, please refer to Figure 3 and Figure 10The fixing unit includes a mounting port 108 on the outer wall of the mounting bracket 102. A limiting screw 109 is fixedly installed on the side wall of the hydraulic cylinder 103, and the limiting screw 109 passes through the mounting port 108. A nut 110 is threadedly connected to the outer side of the limiting screw 109, and a washer 111 is also sleeved on the outer side of the limiting screw 109. The washer 111 is located between the nut 110 and the mounting bracket 102. The position of the hydraulic cylinder 103 on one side of the mounting bracket 102 can be flexibly adjusted. By tightening the nut 110 on the outer side of the limiting screw 109, the washer 111 is squeezed, which can lock the position of the hydraulic cylinder 103. The flexibly detachable hydraulic cylinder 103 also facilitates the inspection and maintenance of the equipment and makes it more convenient to use.

[0042] As one embodiment of the present invention, please refer to Figure 5 and Figure 7 The shifting unit includes a telescopic cylinder 201 fixedly mounted on the lower surface of the workbench 101. A displacement plate 202 is fixedly installed at the telescopic end of the telescopic cylinder 201. A first upright 203 is fixedly mounted on the upper surface of the displacement plate 202, and the first upright 203 is located in the movable opening 107. A first rotating cylinder 204 is rotatably sleeved on the outer side of the first upright 203. When the wind turbine flange is placed on the surface of the workbench 101, its side can be in contact with the first rotating cylinder 204. Then, the displacement plate 202 can be moved by the telescopic cylinder 201, so that the first upright 203 can be moved together. The position of the wind turbine flange can be adjusted so that the punch head 105 is aligned with the position on the surface of the wind turbine flange that needs to be punched, which is very convenient to use.

[0043] As one embodiment of the present invention, please refer to Figure 5 , Figure 7 and Figure 8The clamping unit includes a telescopic cylinder 301 fixedly mounted on the lower surface of the workbench 101. A movable plate 302 is fixedly mounted on the telescopic end of the telescopic cylinder 301. The outer wall of the movable plate 302 has symmetrically distributed limiting openings 303, and the inner walls on both sides of the limiting openings 303 have sliding grooves 304. A movable block 305 is movably mounted in the limiting openings 303. Slide plates 306 are fixedly mounted on both sides of the outer walls of the movable block 305, and the slide plates 306 are slidably mounted in the sliding grooves 304. A second upright 307 is fixedly mounted on the upper surface of the movable block 305, and the second upright 307 is located in the movable opening 107. A second rotating cylinder 308 is rotatably sleeved on the outer side of the second upright 307. The inner walls of 305 and the limiting port 303 are connected by the first spring 309. After the punching position of the wind turbine flange is determined, the moving plate 302 can be moved by the telescopic cylinder 301, so that the second rotating cylinder 308 on the outside of the second upright 307 fits against the wind turbine flange. As the moving plate 302 moves further, the moving block 305 can move in the limiting port 303, and the first spring 309 is stretched, causing the second rotating cylinder 308 to apply a moderate clamping force to the wind turbine flange. This ensures stable clamping of the wind turbine flange without affecting the subsequent rotation unit's ability to drive the wind turbine flange to rotate between the first rotating cylinder 204 and the second rotating cylinder 308, resulting in better performance.

[0044] As one embodiment of the present invention, please refer to Figure 6 and Figure 9 The rotating unit includes a telescopic cylinder 401 fixedly mounted on the upper surface of the workbench 101. A bracket 402 is fixedly installed at the telescopic end of the telescopic cylinder 401. A drive motor 403 is fixedly installed in the bracket 402. A rubber wheel 404 is rotatably connected to the drive end of the drive motor 403. When it is necessary to rotate the wind turbine flange, the telescopic cylinder 401 can drive the bracket 402 to move, so that the rubber wheel 404 and the wind turbine flange come into contact. Then, the drive motor 403 drives the rubber wheel 404 to rotate, so that the rubber wheel 404 drives the wind turbine flange to rotate together, realizing the rotation operation of the wind turbine flange, which is very convenient to use.

[0045] As one embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The positioning unit includes a positioning port 501 formed on the outer wall of the mounting bracket 102, and a telescopic cylinder 4 502 is fixedly installed in the positioning port 501. A telescopic cylinder 503 is fixedly installed at the telescopic end of the telescopic cylinder 4 502, and the telescopic cylinder 503 and the telescopic cylinder 4 502 are vertically distributed. A mounting ring 504 is fixedly installed at the telescopic end of the telescopic cylinder 503, and a positioning component is provided in the mounting ring 504. The telescopic cylinder 503 can be moved in the positioning port 501 by the telescopic cylinder 4 502, thereby... The telescopic cylinder 503 allows the mounting ring 504 at its telescopic end to move longitudinally, and the telescopic cylinder 503 can drive the mounting ring 504 to move laterally, effectively allowing the position of the mounting ring 504 to be flexibly adjusted. After the wind turbine flange is punched for the first time and rotated according to the preset rotation angle, the position corresponding to the top of the hole punched for the first time is the position that the mounting ring 504 needs to be adjusted to. With the help of the positioning component in the mounting ring 504, the hole punched can be positioned, thereby ensuring the accuracy of the next punching and improving the performance.

[0046] As one embodiment of the present invention, please refer to Figure 1 , Figure 3 and Figure 4 The positioning assembly includes a lifting cylinder 505 movably mounted in a mounting ring 504. A baffle 506 is fixedly mounted on the top of the lifting cylinder 505, and a second spring 507 is sleeved on the outer side of the lifting cylinder 505. One end of the second spring 507 is connected to the upper surface of the mounting ring 504, and the other end of the second spring 507 is connected to the lower surface of the baffle 506. A positioning rod 509 is movably mounted in the lifting cylinder 505, and the top of the positioning rod 509 is connected to the inner top wall of the lifting cylinder 505 by a third spring 508. The bottom end of the positioning rod 509 is conical. A lower pressure plate 510 is also fixedly mounted on the outer side of the stamping rod 104. When the stamping rod 104 moves downward, the lower pressure plate 510 drives the lifting cylinder 505 to move downward together. When the hydraulic cylinder 103 drives the stamping rod 104 to move downward... During the punching operation, the lower pressure plate 510 on the outside of the punching rod 104 first contacts the baffle 506, causing the baffle 506 and the lifting cylinder 505 to move downward together. This compresses the second spring 507 and causes the lifting cylinder 505 to move downward in the mounting ring 504. At this time, the positioning rod 509 in the lifting cylinder 505 enters the pre-drilled hole on the surface of the wind turbine flange, compressing the third spring 508 in the lifting cylinder 505. This causes the positioning rod 509 to apply a certain downward pressure to the wind turbine flange, causing the wind turbine flange to move slightly. This effectively compensates for the positional deviation that exists when the rotating unit drives the wind turbine flange to rotate. Then, the punching head 105 penetrates the wind turbine flange to complete the punching operation. This positioning method can greatly improve the accuracy of the wind turbine flange punching process and achieve better results.

[0047] As one embodiment of the present invention, please refer to Figure 3 and Figure 10 A crossbar 511 is also fixedly installed in the mounting bracket 102. A sliding sleeve 512 is fixedly installed on the outer wall of the telescopic cylinder 503, and the sliding sleeve 512 is slidably sleeved on the outside of the crossbar 511. With the help of the sliding sleeve 512, the stability of the telescopic cylinder 503 when moving in the positioning port 501 can be effectively improved, and the use effect is better.

[0048] As one embodiment of the present invention, please refer to Figure 5 and Figure 7 The lower surface of the workbench 101 is also fixedly equipped with symmetrically distributed support frames 602, and the support frames 602 are connected to the lower surface of the workbench 101 through the fixing rod 601. The displacement plate 202 and the moving plate 302 are slidably installed in the support frame 602. With the help of the support frame 602, the stability of the displacement plate 202 and the moving plate 302 when moving can be improved, and the use effect is better.

[0049] It should be noted that although this specification describes the embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
