[0018] Examples:
[0019] A forging process method for multi-branch parts, taking the crankshaft as an example, and completing the following steps:
[0020] a. Blanking heating: heating the round bar blank after blanking.
[0021] b. Flattening: such as figure 1 As shown in the 4 pictures on the left side, one end of the round bar blank is placed on the pressing die 1, and the pressing die 1 is closed once and one end of the round bar blank is squashed.
[0022] c. Rough suppression: such as figure 1 As shown in the 4 pictures on the right side, the flattened end of the round bar blank is vertically inserted into the "V" groove 3a of the blanking cavity of the pressing die 1, and the other end of the round bar blank is rough-pressed to Obtain a blank whose contour matches the cavity of the pre-forging die; the two steps b and c are completed on a pressing die 1.
[0023] d. Forging forming: Put the finished blank into the pre-forging die for pre-forging; then put the pre-forged blank...
