Description

Technical Field

[0001] The invention relates to the technical field of copper wire drawing, in particular to a copper wire continuous drawing device for a copper wire production line. Background Art

[0002] Copper wire is a conductive conductor made of copper. Due to its excellent electrical conductivity, ductility, corrosion resistance, strength, oxidation resistance, and long service life, copper wire is primarily used in the manufacture of electrical products, including generators and transformers. Copper wire production typically involves stretching. Wire stretching involves a series of steps to transform raw copper wire into a finished product of the desired diameter and length.

[0003] In the prior art, copper wire is primarily drawn using a wire drawing machine. During this process, a thick copper wire is passed through the die hole of a wire drawing die, and tension is applied to one end of the copper wire, causing the outer diameter of the thick copper wire passing through the wire drawing machine to become the same as the inner diameter of the die hole, achieving a thinning effect. As the copper wire passes through the die hole, burrs and copper powder form due to the rupture of the oxide layer on the copper wire's surface. Furthermore, due to the limitations of the die hole, metal debris generated by the burrs and copper powder falls off and accumulates at the entry angle of the die hole. As processing time increases, the accumulation of metal debris at the entry angle of the die hole increases, which can easily affect the surface quality of the drawn copper wire and increase the resistance of the copper wire entering the die hole, making the copper wire more likely to break.
