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...

Embodiment Construction

[0024] Such as figure 1 and figure 2 As shown, the present invention discloses 3 sets of two-roll rolling mills and 7-die wire drawing machines combined continuous rolling and continuous drawing machine, including rod release device 1, 3 sets of twin-roll mills 2, 7-die wire drawing machine 3, fixed speed wheel 4, and annealing device 5. The wire storage wheel set 6 and the wire take-up device 7.

[0025] In the unit of the present invention, the rod-releasing device 1, the fixed speed wheel 4, the annealing device 5, the wire storage wheel group 6 and the wire take-up device 7 can be the same as the existing common 13-mode large drawing machine. The rear 7 of the 7-die wire drawing machine 3 of the present invention is exactly the same as the common 13-die drawing machine. The 3 groups of two-roll mills 2 are composed of 3 groups of independent rolling mills 31 , 32 and 33 .

[0026] The rod releasing device 1 has a copper rod inlet and a copper rod outlet. The copper rod...
