Description
technical field [0001] The invention relates to the field of welding wire production, in particular to a friction device for a wire drawing machine. Background technique [0002] Welding is a dust-producing process commonly used in workpiece connection. Most welding processes require welding wire. When welding, the welding wire and workpiece need to be melted, and then pressure is applied. After cooling, the workpiece will form a permanent connection. During the production of welding wire, it is necessary to remove the metal oxide layer on the surface of the metal wire blank with a thicker diameter, then remove the oil stain, and then draw it to make the diameter meet the product requirements. During the drawing process, the welding wire needs to be drawn on multiple dies. After each drawing, the welding wire must be wound on the reel first. In order to make the welding wire tightly wound on the reel, it is necessary to set the Friction disc, the wire puller of the existing...
