Abstract
The invention discloses an anti-torsion traction device for a reinforcing bar hoop bending machine. The anti-torsion traction device comprises a traction main shaft of which one end is connected with a power device and hinged with and supported on a traction board, a main traction wheel arranged at the other end of the traction main shaft, a compaction wheel positioned above the main traction wheel, and a down-pressing mechanism connected with the compaction wheel, wherein the main traction wheel is arranged between two groups of straightening wheel groups with the same height, so a dragged reinforcing bar passes through the main traction wheel and the two groups of straightening wheel groups and is formed into a cambered shape; and the compaction wheel pressed on the cambered reinforcing bar which is coiled through the main traction wheel. The anti-torsion traction device has the advantages that: the reinforcing bar moves between the main traction wheel and the straightening wheels in a circular arc path, so the reinforcing bar can release stress fully; and torsion can be avoided after the reinforcing bar is straightened and bent. By enlarging a contact area between the reinforcing bar and the main traction wheel, a slipping phenomenon during traction of the reinforcing bar can be avoided and the quality of the reinforcing bar can be improved; and the anti-torsion traction device has the advantages of simple structure, convenience for maintenance, conservation of energy consumption, stable work and low cost.
