Drawing die for copper wire production

Abstract

The invention relates to a drawing die for copper wire production. The drawing die comprises a bottom plate, a lubricating die, a wire drawing die and a cooling die; the lubricating die is installed on the left side of the upper end face of the bottom plate; the cooling die is installed on the right side of the upper end face of the bottom plate; and the wire drawing die is located between the lubricating die and the cooling die. The drawing die for copper wire production is capable of solving the problems that the lubricating die and the cooling die of an existing wire drawing die are inconvenient to detach from the wire drawing die, powder generated in the wire drawing process is difficult to clean, the lubricating degree in a wire drawing hole is affected after a long time, the wire drawing effect is affected, a lubricant cannot be evenly smeared on the surfaces of wires before wire drawing, the wires cannot be well guided during wire drawing, resulting in track deviation during wire drawing and enabling the wire drawing success rate and the wire drawing quality to be affected, and the surfaces of the wires cannot be cooled in time after wire drawing such that the quality of thesurfaces of the wires after wire drawing and the mechanical property of the wires are affected.

Description

technical field [0001] The invention relates to the technical field of drawing dies, in particular to a drawing die for producing copper wire. Background technique [0002] The wire drawing die refers to a tool that forces the metal to pass through the die under the action of an external force in the process of metal pressure processing, the cross-sectional area of ​​the metal is compressed, and the required cross-sectional shape and size are obtained. The basic principle of wire drawing die wire drawing: wire drawing refers to a pressure processing method in which the wire billet undergoes plastic deformation through the die hole under a certain tension to reduce the cross section and increase the length. Except for very little powder, the volume changes little, so the volume of the metal before and after stretching is basically equal. The wire drawing die has the characteristics of more accurate size of the drawn wire, smooth surface, various cross-sectional shapes, abili...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that most of the lubricating dies and cooling dies of the existing wire drawing dies are connected together with the wire drawing dies, which makes it inconvenient to disassemble the lubricating dies and cooling dies, and it is difficult to clean the powder chips generated during the wire drawing process, which takes a long time It affects the lubricity inside the wire drawing hole, which in turn affects the wire drawing effect, and the quality of the wire surface after wire drawing. It can also solve the problem that the existing wire drawing die cannot evenly apply lubricant to the wire surface before drawing. When the wire is not well guided, the wire will deviate from the track during wire drawing, which will affect the success rate of wire drawing and the quality of wire drawing. After the wire is drawn, the surface of the wire cannot be cooled in time, which will affect the quality and Problems Affecting the Mechanical Properties of Wire Rods
