Description

Wind-powered electricity generation main shaft metal mold Technical Field The invention relates to the technical field of wind power main shaft dies, in particular to a wind power main shaft metal die. Background The wind power main shaft is used as a core bearing component of the wind generating set, and the casting quality directly determines the running stability and the service life of the set. In the wind power main shaft casting process, a metal mold casting process is generally adopted, dedicated molten metal in a molten state is injected into a mold cavity for molding, and meanwhile, a open riser is arranged to realize the feeding function of the molten metal so as to compensate the volume shrinkage of a casting in the solidification process and avoid the defects of shrinkage cavity, shrinkage porosity and the like. However, impurities such as oxidizing slag and the like are inevitably generated in the casting and feeding process of molten metal, and the impurities are easy to float above the liquid level of the open riser due to small density, and if the impurities are not cleaned timely, the impurities possibly mix into the casting along with the molten metal in a backflow manner, so that slag inclusion defects are generated in the casting, the density and mechanical properties of the casting are seriously reduced, and even safety accidents are caused. At present, the wind power main shaft casting industry mainly adopts a traditional treatment mode aiming at open riser impurity cleaning, and the related technology has a plurality of shortages to be solved, specifically as follows: The impurity cleaning timeliness is poor, the casting operation is required to be interrupted, namely the prior art adopts an off-line cleaning mode, namely the impurities in the open riser can be cleaned only after the casting operation is finished or suspended. The method can not realize real-time dynamic cleaning in the casting process, and part of fine impurities are easy to mix into molten metal again due to long-time accumulation of impurities, so that the risk of slag inclusion of the casting is increased, meanwhile, the whole period of casting molding is greatly prolonged due to operation interruption, and the production efficiency is reduced. The impurity and the molten metal are not thoroughly separated, the molten metal is seriously wasted, the traditional cleaning device mainly adopts a simple salvaging or adsorbing mode to remove the impurity, a special separation structural design is lacked, the unset molten metal is easily carried out together in the impurity cleaning process, a large amount of molten metal is wasted, the production cost is improved, the salvaging or adsorbing precision is low, the oxidizing slag above the liquid level is difficult to thoroughly clean, and the cleaning effect is poor. The automatic degree is low, the potential safety hazard is remarkable, the existing cleaning operation depends on manual operation, operators need to closely contact high-temperature molten metal and a die, the labor intensity is high, serious potential safety hazards such as molten metal splashing and high-temperature scalding are faced, meanwhile, the manual operation accuracy is greatly affected by the artificial factors, the problems of impurity scattering and secondary pollution to the die or castings are easy to occur, and the quality stability of the castings is further affected. The feeding channel is easy to block, the defect rate of the casting is high, molten metal in the open riser is easy to solidify too quickly due to temperature drop in the impurity cleaning interval, the feeding channel is blocked and continuous feeding cannot be realized, uneven distribution of components and temperature of the molten metal is easy to occur in the solidification process, the occurrence rate of defects such as shrinkage cavity and shrinkage cavity is further increased, and the severe requirement of the wind power main shaft on the high quality of the casting is difficult to meet. Therefore, the invention provides a wind power main shaft metal mold to solve the problems. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a wind power main shaft metal mold for solving the problems in the background art.
