[ background of the invention ]
Wire drawing die means a tool that forces metal through the die under the action of an external force during the metal press working process, the cross-sectional area of the metal is compressed, and the desired shape and size of the cross-sectional area is obtained. The inner hole area of the main working area of the wire-drawing die is an inner hole, namely a wire passing hole. The copper wire enters the wire-drawing die from the inlet, passes through the wire-drawing die under the action of the drawing force, is subjected to severe friction on the conical surface of the working area of the wire-drawing die, and is drawn out from the outlet to obtain the thinner copper wire. The copper wire bears large extrusion friction force in the sizing area, and a large amount of friction heat is generated.
The existing die is insufficient in lubrication of the copper wire, and an external cooling mode is adopted, so that heat generated during drawing of the copper wire cannot be taken away in time, the die is easy to damage, and the service life of the die is shortened.
