The present invention relates to a screw forming device for reinforcing bars capable of forming screws at the end of reinforcing bars to connect the two reinforcing bars used in a construction site to each other. According to the present invention, the screw forming device for reinforcing bars comprises: a rotary motor (100) for generating rotation power using a power source supplied from outside; a rotary shaft (200) arranged in one side of the rotary motor (100) and rotated by the rotation force of the rotary motor (100); a fixing member (300) surrounding the outer surface of the rotary shaft (200) and supporting the rotary shaft (200) to be rotated; multiple forming dies (400) arranged in one side of the rotary shaft (200) and separated from each other to form the male screws on the outer surface of materials; an attachment member (500) arranged in the outside of the multiple forming dies (400) and forcibly collecting the multiple forming dies (400) to the center of the rotary shaft (200); and a hydraulic cylinder (600) arranged in one side of the attachment member (500) and forcibly moving the attachment member (500) in the axial direction of the rotary shaft (200). According to the present invention, the forming accuracy of the screws can be increased. |
