图1所示是我厂向美国太平洋联合公司提供的锻造法兰盘的成品零件图,材质为A105-77(相应我国30钢),它用于耐温耐压油管路上,所以对其质量要求高。法兰盘的锻造是关键环节,难度又比较大,如果锻造不好,就很难保证零件的尺寸、形状和质量,还会给下道工序带来麻烦。经过我们反复试验,终于用翻挤成型工艺试锻成功,并投入了批量生产。该工艺适 Figure 1 shows the factory to the United States Pacific Union forged flange finished parts map, the material is A105-77 (corresponding to China’s 30 steel), it is used for temperature and pressure on the oil pipeline, so its quality requirements high. Forging the flange is the key link, the difficulty is relatively large, if the forging is not good, it is difficult to ensure the size, shape and quality of the parts, but also to the next procedure to bring trouble. After our repeated tests, finally with the squeeze forming process forging success, and put into mass production. The process is suitable
