Cupreous metal wire-drawing on-line heat treatment method and on-line heat treatment device

Abstract

The invention provides a cupreous metal wire-drawing on-line heat treatment device which comprises a wire drawing machine, wherein a wire outlet end of the wire drawing machine is connected with the inlet of an electromagnetic heating coil inlet of an electromagnetic induction heating facility, and the outlet of the electromagnetic heating coil is connected with the inlet of a cooling water tank; and the outlet of the cooling water tank is connected with a take-up pulley. The device is scientific in design, implements on-line annealing, and enhances the toughness and electric conductivity of the drawn copper wire. The invention also provides an on-line heat treatment method of the cupreous metal wire-drawing on-line heat treatment device, which comprises the following steps: 1. wire drawing; 2. on-line heat treatment; 3. water cooling; and 4. taking up. By carrying out heat treatment on the drawn cupreous metal wire, the method is scientific in design and enhances the toughness and electric conductivity of the drawn copper wire.

Description

technical field [0001] The invention relates to a heat treatment device, in particular to an online heat treatment device for copper metal wire drawing, and also relates to an online heat treatment method based on the device. Background technique [0002] In the traditional wire and cable manufacturing industry, the method of manufacturing copper wires is to directly draw copper metal materials (or copper rods) on a wire drawing machine.
