Forming die forging forming method for T-shaped sheet forgings

The invention discloses a loose tooling forging forming method for T-shaped sheet forgings, which adopts T-shaped loose tooling forging forge piece design, T-shaped loose tooling design, T-shaped blank design, square blank design, blanking design and forming process sequence design, and comprises the following steps: preparing a square blank with an intermediate value thickness through the design scheme, and then pressing shoulders in the length direction and drawing out an intermediate plate; according to the forming method, the thickness sectional area difference is formed, the stability of the middle plate and the shape and size of the final forge piece are guaranteed through the forming die, the upset head supporting plate is arranged at the other end, the thickness sectional area difference is further enlarged, and therefore the forging ratio limitation of a single forming mode is exceeded, and the forming method has the advantages that the forming problem is solved, the forge piece machining allowance i
