Thread rolling machine special for double-thread screw

The utility model discloses a thread rolling machine special for a double-thread screw. The thread rolling machine special for the double-thread screw comprises two main shafts, a machine tool main base and a transmission system. The machine tool main base comprises a fixed main base body and a sliding main base body. The fixed main base body is directly connected with one main shaft. The sliding main base body is indirectly connected with the other main shaft. Two oil cylinders are installed on the sliding main base body and push the sliding main base body, and the sliding main base body can advance and retract in the machining process. Proportional servo closed-loop control is applied to the two oil cylinders, and therefore synchronous advancing of the sliding main base body can be more accurate and more reliable. The thread rolling machine special for the double-thread screw is simple in structure, stable in operation, high in machining efficiency, small in workpiece deformation and high in machining precision.
