一、摆动辗压锻造工艺根据辗压温度的不同,摆动辗压锻造分为热辗压、温辗压、冷辗压三种方式。波兰用冷辗加工φ100毫米的工件,尺寸精度可达0.025毫米;摆头转数200转/分,摆辗时间5～10秒,摆角1°～2°。温辗的辗压力比冷辗约可减小二分之一,并且不象冷摆辗那样容易产生镦粗裂纹。另外,当热辗压时,温度达到高温区域,氧化皮的生成量和晶粒的粗大化都变得严重,因而工件表面状态和机械性能都不好。而温辗是在500～800℃范围内进行的,避免 First, the swing rolling forging process according to the different rolling temperature, swing rolling forging into hot rolling, warm rolling, cold rolling three ways. Poland with cold rolling processing φ100 mm workpiece, dimensional accuracy of up to 0.025 mm; swing speed of 200 rev / min, swing time of 5 to 10 seconds, swing angle 1 ° ~ 2 °. The temperature of the roller can be reduced by about one-half of that of the roller by the cold roller, and it is not as prone to upsetting cracks as cold rollers. In addition, when hot rolling, the temperature reaches a high temperature region, the formation of scale and grain coarsening become serious, so the workpiece surface conditions and mechanical properties are not good. The temperature roller is carried out in the range of 500 ~ 800 ℃, to avoid
