Description

Technical Field

[0001] The present invention relates to the technical field of punching processing, and in particular to a wind power flange processing and punching device. Background Art

[0002] In the field of wind turbine equipment manufacturing, wind turbine flanges are essential components that connect key components such as towers and hubs. Their processing quality plays a decisive role in the stability and safety of wind turbine generator sets. However, existing wind turbine flange punching equipment faces many problems that need to be solved in practical applications.

[0003] First, traditional equipment lacks an effective clamping and calibration mechanism when positioning wind turbine flanges, and often relies on manual adjustment. This is not only inefficient, but also difficult to ensure the accurate positioning of the flange during the processing process. Hole position deviation is prone to occur, resulting in an increased scrap rate.

[0004] Secondly, traditional punching equipment has poor versatility. Its punching heads are usually of fixed specifications and cannot be flexibly replaced according to different punching needs. It is difficult to meet diverse processing requirements. When holes of different sizes and shapes need to be processed, the entire set of equipment often needs to be replaced, 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 ensure the accuracy of the rotation angle when rotating the flange to process the next hole, and there is a lack of a secondary positioning calibration mechanism, which makes it difficult to control the positional accuracy between subsequent holes and processed holes, seriously affecting the overall quality of the wind turbine flange. Especially when processing wind turbine flanges with high precision requirements, this defect of traditional equipment is particularly prominent, and it cannot meet the high-precision requirements of modern wind power generation equipment for components.

DETAILED DESCRIPTION

When the wind turbine flange needs to be rotated, the telescopic cylinder 3 401 can be used to drive the bracket 402 to move, so that the rubber wheel 404 and the wind turbine flange fit together, and then the driving motor 403 drives the rubber wheel 404 to rotate, so that the rubber wheel 404 can drive the wind turbine flange to rotate together, thereby realizing the rotation operation of the wind turbine flange, which is very convenient to use.

[0029] As an embodiment of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The positioning unit includes a positioning port 501 provided on the outer wall of the mounting frame 102, and a telescopic cylinder 502 is fixedly installed in the positioning port 501, a telescopic cylinder 503 is fixedly installed at the telescopic end of the telescopic cylinder 502, and the telescopic cylinder 503 and the telescopic cylinder 502 are vertically distributed, and 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, and the telescopic cylinder 503 can be driven to move in the positioning port 501 by the telescopic cylinder 502, thereby The mounting ring 504 at the telescopic end of the telescopic cylinder 503 can move longitudinally, and the mounting ring 504 can be driven to move horizontally by the telescopic cylinder 503, thereby effectively realizing that the position of the mounting ring 504 can 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 first punched hole is the position that the mounting ring 504 needs to be adjusted.

During the punching operation, the lower pressure plate 510 on the outside of the punching rod 104 will first contact the baffle 506, and drive the baffle 506 and the lifting cylinder 505 to move downward together, causing the second spring 507 to be compressed, and causing the lifting cylinder 505 to move downward in the mounting ring 504. At this time, the positioning rod 509 in the lifting cylinder 505 will enter the hole that has been opened on the surface of the wind turbine flange, and cause the third spring 508 in the lifting cylinder 505 to be compressed, causing the positioning rod 509 to apply a certain downward pressure on the wind turbine flange, causing the wind turbine flange to move slightly, which can effectively compensate for the position deviation when the rotating unit drives the wind turbine flange to rotate. Then the punching head 105 will penetrate the wind turbine flange to realize the punching operation.
