Copper wire circulating heating annealing furnace

Abstract

The invention discloses a copper wire circulating heating annealing furnace. The copper wire circulating heating annealing furnace comprises an annealing box, wherein a rotating shaft driven by a motor is rotationally connected to the bottom of the annealing box, a rotating disc is fixedly connected to a rotating shaft in the annealing box, electric heating wires capable of being electrified are arranged on the inner wall of the annealing box, a hollow supporting cylinder is arranged between the rotating disc and the bottom of the annealing box, a plurality of hot air holes communicating withthe supporting cylinder are formed in the bottom of the rotating disc in the circumferential direction of the rotating shaft, air inlet pipes communicating with the supporting cylinder are arranged atthe bottom of the annealing box, and air outlet pipes are arranged between the supporting cylinder and the annealing box; the rotating shaft outside the annealing box is fixedly connected with driving gears, the driving gears are meshed with driven gears, the driven gears are connected with air cylinders, air inlet one-way valves and air outlet one-way valves are arranged on the side walls of theair cylinders between the bottom of the air cylinders and pistons, the air inlet one-way valves are connected with the air outlet pipes, and the air outlet one-way valves are connected with the air inlet pipes. According to the technical scheme, heating in the copper wire annealing furnace is uniform, and oxidation and excessively high gas pressure cannot appear.

Description

technical field [0001] The invention belongs to the technical field of cable production equipment, in particular to a copper wire circulating heating annealing furnace. Background technique [0002] In the production process of wire and cable, such as: communication cables, plastic cables, high-voltage cables, electromagnetic wires, etc., copper conductors are required to be soft cores that have been annealed. The most basic requirement is that the surface of the copper conductor is bright, non-oxidizing, Burns are not allowed, and all are required to meet the conductor performance required by wire and cable products. At present, several common methods for annealing copper conductors include: annealing furnace annealing, heat pipe annealing, contact annealing, induction annealing, etc. The annealing furnace annealing equipment is mainly composed of annealing tank, heating wire, etc. The annealing method is: drawing wire The formed copper coil wound on the take-up frame is p...
