叶片锻件种类繁多,数量庞大,质量要求高。生产上总的趋势是用精密模锻替代普通模锻,使叶身部分精锻至具有均匀余量的精密尺寸。合理的工艺和模具设计是保证试制和生产顺利进行的重要条件。在设计阶段,借助“工艺模型”,利用计算机能计算出许多重要内容,供设计者选择和应用:1.利用数值方法对型面和锻件各部分体积进行计算,确定毛坯的尺寸。 Vane forging a wide range of large quantities, high quality requirements. The general trend in production is to use precision forging instead of ordinary forging, so that the blade part of the precision forging to a precision margin size. Reasonable process and mold design is to ensure the trial and production of an important condition for the smooth progress. In the design stage, with the help of “process model”, many important contents can be calculated by computer for designers to choose and apply: 1. Using the numerical method to calculate the volume of each part of the surface and forgings to determine the size of the blank.
