Rolling device for rebar end thread

The utility model provides a rolling device for a rebar end thread. Each rolling wheel (8) is respectively sleeved on a vertical circular shaft (61) of a T-shaped roller seat (6), a horizontal I-shaped sliding block (62) of the T-shaped roller seat (6) and an I-shaped groove pointed to the center of a circle, on the rolling head base are embedded, and internal threads of the T-shaped roller seat are screwed with adjusting screw rod gear shafts (4). Conical gears of each adjusting screw rod gear shaft (4) are constant-radially positioned on the rolling head base (6) via bearing blocks and are engaged with a conical fluted disc (2). When one adjusting screw rod gear shaft is rotated, end straight thread rolling machining of Phi 12 to Phi 40 of the rebar of various diameter specifications can be achieved by one rolling end and one pair of rolling wheels.
