Process for producing lower swing arms of automobiles

The invention discloses a process for producing lower swing arms of automobiles. The process includes steps of pre-forging, edge trimming, forking, splitting, finish forging, edge trimming and the like. The process has the advantages that forking treatment is required, and accordingly the length of each blank required to be prepared for initial pre-forging can be shortened by nearly a half; the machining allowance is low in machining procedures, the production cost and the machining difficulty can be effectively lowered, accordingly, the machining precision can be greatly improved in follow-up steps, and the quality of products can be effectively enhanced.
