The invention discloses a device for straightening a steel wire split from a steel
wire rope. A base disc, three supports, a stepping motor, a
ball screw, two guide rails, a clamping mechanism, a straightening wheel frame, four straightening wheels, a supporting frame, a synchronous belt, two synchronous belt wheels, a feeding
assembly and a pre-tightening mechanism are installed inside an
enclosure. The steel wire to be straightened penetrates from a point B to a point A, sequentially passes through the pre-tightening mechanism, the feeding
assembly and the four straightening wheels, and is clamped by the clamping mechanism. The stepping motor is started to drive the
ball screw to rotate, and then the two synchronous belt wheels and the straightening wheel frame are further driven to rotate simultaneously, so that the steel wire can be straightened in an omnibearing mode. The
ball screw rotationally drives the clamping mechanism to move leftwards. The steel wire is pulled out from the point B to the point A, and straightening of the steel wire is achieved. An experiment with the device shows that the split steel wire with the
diameter below 3 mm can be straightened, and the requirements of tensioning, twisting and repeatedly bending the steel wire subsequently are met. In addition, the surface of the steel wire is basically not damaged, the performance of the steel wire is not damaged, equipment is easy to operate, and the operation speed is adjustable.
