Sizing, polishing and damping device in welding wire production process

The utility model provides a sizing, polishing and damping device in a welding wire production process. A first groove body, a second groove body, a sizing module and a vibration reduction module aresequentially arranged in the operation direction of the welding wire, so that when the sizing, polishing and vibration reduction device is used, the welding wire can sequentially penetrate through thefirst groove body, the second groove body and the sizing module and make contact with the top of the cushion block, and the vibration reduction module comprises at least one cushion block. Accordingto the sizing, polishing and damping device in the welding wire production process, sizing and polishing can be conducted on the welding wire subjected to copper plating and drying in the welding wireproduction process, violent vibration of the welding wire after polishing can be effectively prevented, and the quality problems that the welding wire is large in size, hard to bend, uneven in copperlayer thickness and the like
