Combined continuous rolling and continuous drawing machine with three sets of double-roller rolling machine and seven die drawing machines

Abstract

The invention discloses a combined continuous rolling and continuous drawing machine with three sets of double-roller rolling machine and seven die drawing machines. According to the invention, a rod charging device is provided with a copper rod inlet and a copper rod outlet; the copper rod outlet corresponds to the first rolling channel inlet of the three sets of double-roller rolling machine; the rolling channel outlet of a previous set of the three sets of double-roller rolling machine corresponds to the rolling channel inlet of a next set of the three sets of double-roller rolling machine; the rolling channel outlet of the last set of the three sets of double-roller rolling machine corresponds to the first drawing channel inlet of the seven die drawing machines; the drawing channel outlet of a previous die of the seven die drawing machines corresponds to the drawing channel inlet of a next die of the seven die drawing machines; the last drawing channel outlet of the seven die drawing machines corresponds to the inlet of a constant-speed wheel; the outlet of the constant-speed wheel corresponds to the inlet of an annealing device; the outlet of the annealing device corresponds to the inlet of a wire-storing wheel set; and the outlet of the wire-storing wheel set corresponds to the inlet of a wire take-up device. With the combined continuous rolling and continuous drawing machine provided by the invention, an 8-mm oxygen-free copper rod can be drawn into a copper wire with a desired specification after rolling by the three sets of rolling machine, so a copper wire with a diameter of 0.10 mm or below can be produced through processing; the processed copper wire has a uniform and fine lattice structure, which is beneficial for reduction in defects and continuation of advanced processing; and energy consumption in production of copper wires with unit weight is substantially decreased.

Description

technical field [0001] The invention relates to a continuous rolling and continuous drawing machine combined with 3 sets of double-roll rolling mills and 7-die wire drawing machines, in particular to a 8-10mm copper rod stretched or rolled and then stretched to the required specifications in the production of electric wires and cables copper wire equipment. Background technique [0002] At present, in the production of wire and cable conductors, the raw materials of copper conductors are usually 8mm copper rods produced by continuous casting and rolling, and 17mm oxygen-free copper rods produced by the up-drawing method are directly produced by 8mm oxygen-free copper rods and up-drawing methods after being cold-rolled by a rolling mill. 8mm copper rod, the copper wire produced by the first two raw materials has a uniform and fine structure lattice, which is suitable for continuous processing to fine copper wire below 0.10, but the cost is relatively high. However, the 8mm o...

[0002] At present, in the production of wire and cable conductors, the raw materials of copper conductors are usually 8mm copper rods produced by continuous casting and rolling, and 17mm oxygen-free copper rods produced by the up-drawing method are directly produced by 8mm oxygen-free copper rods and up-drawing methods after being cold-rolled by a rolling mill. 8mm copper rod, the copper wire produced by the first two raw materials has a uniform and fine structure lattice, which is suitable for further processing to fine copper wire below 0.10, but the cost is relatively high

However, the 8mm oxygen-free copper rod produced by the upward drawing method cannot be further processed because it has not been cold-rolled by a rolling mill, and the crystal lattice is thick and uneven.
