分别从锤头工作表面的形状、工作表面整形段的尺寸、锤头锥角、锤头数目分析了锤头对径向锻件锻透性的影响,得出的结论是:使用含有预成形段的锤头有利于提高锻件的锻透性;双圆弧形工作表面的锤头比凹圆弧形工作表面的锤头更有利于锻件表面的成形和心部的锻透;锻件的锻透性随锤头工作表面的尺寸减小而增大;锻件的锻透程度随锤头锥角的增大而增加;对锤头工作面的合理设计有利于锻件心部压实;生产效率随锤头数目的增加而增加,但对锻透性没有影响。
The influence of the hammerhead on the forging of radial forgings was analyzed respectively from the shape of the working surface of the hammerhead, the size of the plastic section of the working surface, the cone angle of the hammerhead and the number of the hammerheads. The conclusion was drawn as follows: Hammerhead is conducive to improve the forging of the forging; double circular arc working surface of the hammer than concave circular arc working surface hammer is more conducive to forging surface forming and heart of the Ministry of forging; The size of the working surface of the hammer decreases and increases; the degree of forging of the forging increases with the increase of the cone angle of the hammerhead; the reasonable design of the working face of the hammerhead is favorable for the forging heart compaction; the production efficiency increases with the number of the hammerheads Of the increase, but no effect on the permeability.
