The invention relates to a processing technique for large flange short-axle type parts. The invention is characterized in that: the processing technique comprises the processing procedures of refining, forging, heat treating, detecting, and machining. The forging processing procedure is that: firstly a preformed stock is forged by free forging on a large-size hydraulic machine, and secondly, the preformed stock is placed in the die to be vertically upset forged into a die-forging part the dimension of which is approximate to that of a finish product. The invention overcomes the drawbacks that the large water press can only freely form by large-size forging piece, and can save raw materials and shorten cold processing time. The invention has the most advantage that the processing technique improves forging ability of the large flange arranged at the end of large flange short-axle parts.
