Under what conditions can one material forging die forging method be used

The one-material multi-forging die forging method has certain constraints (or unsuitable conditions). As long as one of the following contents is not suitable for one-material multi-forging (especially not suitable for one-die multi-forging, continuous multi-forging, U-turn die forging and Compound die forging and other forming methods): such as heavy forgings, large horizontal projection area of forgings, too complicated forging shapes, too narrow forging temperature range, large forging die bore depth, excessive final forging deformation without blank forming, The number of billet making steps in one-fire forging is ≥3, the number of forging dies needs to be increased, and the number of forging equipment needs to be increased, etc. The one-material multi-forging die forging method is a systematic project. Effectively determining the constraints and suitable conditions is one of the prerequisites for achieving the reliability, effectiveness and timeliness of the one-material multi-forging.
