补充资料:锻压:径向锻造
        专门加工实心或空心长轴类零件的旋转锻造方法。锻造时﹐分布在棒料圆周方向的锤头(2~8个)对工件快速和同步锻打。如工件为圆截面﹐则一面低速旋转﹐一面轴向进给移动﹔如工件为非圆截面﹐则只轴向进给而不旋转。径向锻造的特点是不需要专用模具﹐能按预定程序锻出精密的轴类零件。径向锻造每次压缩量小﹐每分鐘锻打次数高﹐一般为240~1800次/分﹐能提高金属的塑性。这种方法可用於热锻或冷锻。图 径向锻造件 为常见的径向锻造件形式。锻件的精度﹕热锻的外径±0.5毫米﹐内径±0.1毫米﹔冷锻的外径±0.1毫米﹐内径±0.01毫米。
         径向锻造所用设备分精锻机和轮转锻机两类。用精锻机锻造时﹐工件一面轴向送进一面旋转﹐锤头径向锻打。这类机器多用程序控制﹑数字控制或微处理控制系统自动操作﹐生產效率高﹐用以建立热锻火车轴等自动生產线和冷锻枪管来复线等。精锻机有立式和卧式之分。还有一种设备锻造时﹐工件只送进﹐不旋转﹐多用於钢厂﹐将钢锭直接锻成方钢﹑扁钢等。轮转锻机有2或4个锤头﹐锤头一面围绕工件转动﹐一面对準工件径向锻打﹐工件只轴向送进。轮转锻机结构简单﹐价格低﹐但自动化程度低﹐噪音大。
