Forming die for forming annular forge piece with L-shaped section through loose tooling forging

The forming die comprises a special punch, a forming die and a lower die, the forming die is arranged at the center position in the lower die, a gap formed by the lower die and the forming die is used for containing an annular blank with a rectangular section, the special punch is arranged on the upper end face of the annular blank with the rectangular section, and the special punch is arranged on the lower end face of the annular blank with the rectangular section. The special punch is controlled by the press to move downwards to form the annular blank with the rectangular section, and the special punch, the forming die and the lower die jointly form a cavity of the annular forge piece with the L-shaped section. The die has the advantages of small tonnage of forging forming equipment, easiness in forming control, light weight and the like. The die is suitable for forging forming of the annular forge piece with the L-shaped section. 本发明公开了一种L形截面环形锻件的胎模锻造成形模具，该模具包括专用冲头、胎模和下模，所述胎模置于下模内的中心位置，所述下模与胎模形成的空隙用于放置矩形截面
