汽车转向节在锻造过程中出现的缺陷主要是杆部变形、毛刺、充不满、氧化坑、法兰盘中心处凹坑等,虽可采用加热返修法、砂轮磨削法、堆焊法进行一定的修补,但大多数锻件缺陷,如方形法兰盘四角充不满、叉口耳部充不满、杆部与法兰连接处的根部折纹等,仍无法修复,会造成一定的废品率。转向节质量为22.92kg,采用40MnB及40Cr优质钢材,因此搞好修复工作可取得较大经济效益。
Car steering knuckles in the forging defects are mainly deformed bar, burr, dissatisfaction, oxidation pits, flanges at the center of pits, etc., although the heat can be used rework method, grinding wheel grinding method, welding method for a certain Of the repair, but most of the forgings defects, such as the square flange square charge dissatisfaction, fork ear filling dissatisfaction, the rod and the flange connection at the root of folds, etc., still can not be repaired, will result in a certain rejection rate. The knuckle mass is 22.92kg, using 40MnB and 40Cr high-quality steel, so do a good job of repairing work can get greater economic benefits.
