精锻精锻precision forging 精锻Precision forging在径锻机上完成的塑性加工工艺。精锻件的公差小,表面质量好,形状和尺寸非常接近于产品,一般不需要或只需要少量机械加工就可直接装配使用。 径向精锻加工一般适用于各种轴类零件,其工作过程如图所示。径向精锻分为3种。①锤头旋转式精锻:┌─┐│{ │├─┤│ │└─┘ 径向精银过程 1夹头2工件3锤头坯料只是轴向送进,‘不转动,每次打击时锤头都要绕坯料轴旋转一定的角度。②坯料旋转式精锻:锤头只是打击,坯料在被送进的同时旋转一定的角度。③非回转式精锻:锤头和坯料都不旋转。径向精锻按温度又可分为高温、中温和室温精锻。中温精锻时没有强烈的氧化,但有足够的塑性。室温精锻时虽无氧化,但塑性低,且变形抗力大。 径向精锻的特点是劳动条件较好,生产效率比普通锻造高5一8倍;锤头打击力彼此平衡,并为机身所承受,不需要特殊的基础;锤头形状简单,通用性大,模具的安装和调整都很方便。 径向精锻机分卧式和立式两种。锤头数一般为2一4个,打击次数为200一1200次/分,每个锤头的打击力为600一10000 kN。精锻件的公差大约为普通模锻件的1/3左右(见表)。表面粗糙度:角小于Ra 0 .5双m,有色金属大约为Ra 0 .63一2 .5。径向冷银(娜、价)精度(送进速度1500 mm/min)┌────┬────┬────┬────┬────┬────┬────┬────┐│外径 │1 .6 │3 .2 │6 .3 │13一25 │50一75 │75一llC │>110 │├────┼────┼────┼────┼────┼────┼────┼────┤│尺寸公差│士0 .025│土0 .050│士0 .075│土0 .125│土0 .18 │士0 .25 │士0 .38 ││ (mm) │ │ │ │ │ │ │ │└────┴────┴────┴────┴────┴────┴────┴────┘(谢水生、
