Beschreibung
Zusammenfassung:	The utility model discloses a spiral track straightening machine which comprises an upper die, a lower die and a lower die. The lower die is arranged below the upper die, the top surface of the lower die spirally extends around a vertical axis, a lower spiral groove is formed in the top surface of the lower die, and the lower spiral groove spirally extends along the top surface of the lower die; and the driving mechanism is connected to the upper die or the lower die, and the driving mechanism drives the upper die and the lower die to be close to or away from each other. According to the spiral track straightening machine, the spiral rod piece is placed in the lower spiral groove of the lower die, then the driving mechanism drives the upper die to be close to the lower die, the bottom face of the upper die and the lower spiral groove of the lower die tightly press the spiral rod piece, and the spiral rod piece is shaped and straightened. The workpiece shaping device can be applied to the field of workpiece sh
