Smooth silk polishing machine

The invention relates to the technical field of metal line machining, in particular to a smooth wire polishing machine which comprises a wire rod and further comprises a stretching assembly and a polishing assembly, the stretching assembly comprises a pre-deformation mechanism and a main deformation mechanism, the pre-deformation mechanism comprises a first roller, and the main deformation mechanism comprises a second roller. The polishing assembly comprises a rust removal box, a rotating frame, a first-stage rust removal mechanism and a second-stage rust removal mechanism, the first-stage rust removal mechanism comprises an abrasive belt and a supporting mechanism, an arc-shaped strip plate is arranged on the rotating frame, and the second-stage rust removal mechanism comprises two polishing rotating wheels. And the first-stage rust removal mechanism is used for removing most of iron oxide on the surface of the wire rod, and the second-stage rust removal mechanism is used for conducting all-directional fine
