Problems solved by technology

[0003] In the current market, annealing treatment is required after copper wire drawing to achieve the target physical properties. This process requires continuous transfer of copper, and the heat energy of wire drawing will dissipate naturally. For this, there is an urgent need for a wire drawing process that can be used The thermal energy, and the device that enables the drawing and annealing processes to be completed together

Abstract

The invention provides a copper wire drawing device. The copper wire drawing device comprises a thermal softening device, a wire drawing mold and a water cooling box, wherein a copper wire sequentially penetrates through the thermal softening device, the wire drawing mold and the water cooling box, the copper wire is heated to 160-175 DEG C by the thermal softening device, the wire drawing mold comprises a working area and a sizing area, the diameter of the working area is gradually reduced, the minimum diameter portion of the working area is fixedly connected with the sizing area, the length of the sizing area is larger than the hole diameter, the sizing area comprises a heating section and a heat preservation section, the heating section is provided with a heating coil, the heating coil is used for heating the copper wire to 260-300 DEG C, and the heat preservation section is located between the heating section and the water cooling box. According to the copper wire drawing device, the heat energy generated when the copper is softened in the wire drawing process can be utilized, low-temperature annealing of the copper can be completed in the wire drawing process, and the physical performance of the copper is guaranteed.

Description

technical field [0001] The invention relates to the technical field of copper wire drawing, in particular to a copper wire drawing device. Background technique [0002] A wire drawing machine is a piece of equipment commonly used in copper wire manufacturing, which is used to extrude thicker copper rods into thinner copper wires. During processing, a wire drawing machine pulls thicker copper wire through a die. The copper wire is extruded and thinned as it passes through the die. [0003] In the current market, annealing treatment is required after copper wire drawing to achieve the target physical properties. This process requires continuous transfer of copper, and the heat energy of wire drawing will dissipate naturally. For this, there is an urgent need for a method that can use the wire drawing process. The thermal energy, and the device that enables the drawing and annealing processes to be completed together. Contents of the invention [0004] The object of the pr...
