Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing equipment, in particular to a bare copper wire continuous wire drawing machine. Background Art

[0002] The bare copper wire continuous drawing machine is a device used to produce bare copper wire. It stretches and processes the copper wire through dies with different inner diameters, so that the diameter of the bare copper wire changes from thick to thin. However, the drawing die ring of the existing drawing machine is usually placed directly in a fixed groove, so that the distance between the drawing die ring and the roller cannot be adjusted. In the actual production process, different specifications of copper wire production require different drawing distances. If the distance between the drawing die ring and the roller at the input end is large, during the drawing process, the tension on the side of the drawing die ring close to the input end is prone to decrease, while the copper wire on the other side is tensioned, resulting in a horizontal deviation between the copper wire part with reduced tension and the inner hole of the drawing die ring. In the process of being pulled into the drawing die ring, uneven stretching occurs in different parts, which affects the quality of the copper wire. Utility Model Content
