| description | The invention relates to the technical field of forging, and provides an undercarriage piston rod die forging forging method which comprises the following steps that a bar is subjected to first heating number heating and then free forging, and a semi-finished blank with a large end section at one end is obtained; after the semi-finished blank is subjected to second heating, local small-strain pre-positioning forming is conducted on the large end section of the semi-finished blank through the tool, and a finished blank is obtained; and carrying out third heating on the finished blank, and carrying out die forging to obtain the undercarriage piston rod die forging. According to the forging method of the undercarriage piston rod die forging, the method of blank making and finish forging is adopted, and compared with the two existing methods, the working procedures of pre-forging and annealing and machining shaping are omitted, so that the production cycle of the undercarriage piston rod die forging is shortened |
