Description

Technical Field

[0001] The invention relates to the technical field of wind power flange forging processing, and in particular to a die structure for producing large-scale wind power flange forgings. Background Art

[0002] With the development and promotion of renewable energy around the world, wind power generation has been used more and more widely as a clean energy source. One of the key components of wind power is the flange forging for wind power, which is an important component connecting the wind rotor and the main shaft of the wind turbine. Wind power flange forgings are usually made of high-strength and high-wear-resistant materials to ensure good stability and durability under high-speed operation. At present, the mold structure for producing large-scale wind power flange forgings mostly adopts traditional casting or processing technology, which has problems such as long production cycle, low production efficiency and high cost. At the same time, the traditional mold structure is easily affected by factors such as temperature changes and material deformation during the production process, resulting in uneven product quality and cannot meet the production needs of large-scale wind power flange forgings.

[0003] During the use of the mold structure, since the molten metal needs to enter the lower mold for forming, and the wind flange in the lower mold needs to be impacted during the forming process, the lower mold needs to be fixed and restricted. Otherwise, the lower mold will be moved by being touched, and the upper mold will not be able to fall stably on the flange for processing. After the flange is processed, it needs to be removed and cleaned. Otherwise, the other lower mold will slide here unsteadily, and the upper mold will not be able to fall stably on the lower mold for processing the flange. Summary of the invention

[0004] The disclosed embodiment relates to a mold structure for producing flange forgings for large wind power plants. Liquid metal is poured into a flange forming groove in a lower mold, and an upper mold falls steadily on the flange of the lower mold to be pressed down and formed, and the upper mold quickly hits the wind power flange in the flange forming groove for processing. When the lower mold is hit, a limiting plate and a limiting rod will both fix and limit the lower mold, so that the lower mold will not move when hit. At this time, the upper mold can stably hit the flange for processing. The high-temperature wind power flange that has just been processed can be removed by a hook rod, and then this place can be cleaned with a cleaning plate, and then another lower mold can be smoothly slid here, so that the flange can be continuously processed on the lower mold. Both the upper and lower molds adopt advanced processing technology and materials, have high wear resistance and durability, can operate stably for a long time, improve production efficiency, and ensure stable product quality.
