The present invention relates to an upsetting die for forging, which comprises: a base having a vertical hole formed at a central part; a pickup pad coupled to the vertical hole of the base to be able to be elevated; a die holder formed on the upper surface of the base while being concentric with the vertical hole; an assembly ring die mounted on the die holder to be able to move on a plane and receiving a material (M) in a central part; a few of springs mounted on a predetermined portion of the die holder to support and place the assembly ring die at the center of a die; and a punch pressing the material (M) to form a forged product (M). According to the present invention, the forged product (M) completing processing has a normal shape and dimension even if the central position of the material (M) is out of the center of the die by a predetermined degree, and work stability is improved and breakage of the forged product is minimized, thereby realizing repetitive mass production at a low price.;COPYRIGHT KIPO 2019
