in the in-process of straightening and bending the wire rod reinforcing bar, drive driving gear 43 through driving motor 41 and reducing gear box 42 and slowly rotate, rethread driving gear 43 and the meshing transmission between ring gear 44, can drive reset ring 3 and slowly rotate, and reset ring 3's the direction of rotation is unanimous with the torsion direction of restoration of wire rod reinforcing bar, and then gyro wheel 3111 drives the wire rod reinforcing bar and reverses that resets, and promote the reset rate of wire rod reinforcing bar, torsion deformation when reducing the wire rod reinforcing bar and getting into straightening mechanism, be favorable to promoting the quality of finished product stirrup, and reduce the risk that the wire rod reinforcing bar takes place to damage the inefficacy, be favorable to reducing manufacturing cost, and because gyro wheel 3111 carries out the butt to the periphery wall of wire rod reinforcing bar, be favorable to promoting the effect of straightening in advance to the wire rod reinforcing bar. The device is also suitable for twisting and rectifying the steel wire rods with different sizes, and the application range of the device can be widened. Reset ring 3 can tentatively draw in the wire rod reinforcing bar for in the wire rod reinforcing bar steadily got into straightening mechanism, be favorable to promoting the straightening effect of wire rod reinforcing bar.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
