[0002] Thread rolling machine is a kind of processing equipment for the outer surface of cylindrical workpiece is screwed. The working principle of thread rolling machine is that two identical thread rolling plates with thread rolling surface move relative to each other, thereby rolling thread on the bolt blank between the two thread rolling plates. During the thread rolling process of the workpiece, the workpiece will wear the thread rolling plate of the thread rolling machine. The traditional screw thread rolling machine often ignores the pretreatment of the surface of the workpiece (i.e. screw blank) during the feeding process, especially the lubrication process. The workpiece directly enters the thread rolling die for processing. If the surface lacks necessary lubrication, it will cause the die to wear out, the workpiece surface to be scratched, and excessive friction heat to be generated during the thread rolling process. These problems not only reduce the processing quality and production efficiency of the screw, but also increase the maintenance cost and energy consumption of the equipment.
