Double threaded screw linkage thread rolling device

The utility model discloses double threaded screw linkage thread rolling device, by step motor, pay -off sprocket, pay -off frame, wait to rub with the hands round steel, small -size thread rolling machine, finished product double threaded screw, finished product frame and thread rolling coordinated control ware and constitute, its characterized in that: two equipment symmetrical arrangement of double threaded screw linkage thread rolling device are at two ends of waiting to rub with the hands the round steel, and two step motor hold -in range under the control of thread rolling coordinated control ware moves two pay -off sprocket turns, rub treating on the pay -off frame with the hands round steel and are interrupted through the pay -off sprocket and send into small -size thread rolling machine and carry out the synchronous thread rolling of two ends processing. Compared with the prior art, the utility model, obvious advantage and positive effect below having: the utility model discloses two end synchronous processing screw threads of the round steel of double threaded screw linkage thread rolling device ability target line main part, feed, pay -off reach the automation basically, can practice thrift a large amount of hand labor power, and both available technique and device substitutes and is good at, has improved the automatic level of enterprise again, saving manufacturing cost.
