Problems solved by technology

At present, in the commonly used annealing process of coiling, the coiled hard bare copper wire is usually put into the annealing tank and then placed in the electric furnace for heating and annealing to soften. The annealing temperature is all controlled by the electric furnace. The actual temperature in the tank cannot be kept consistent with the set heating temperature of the electric furnace, which may easily cause the copper wire to fail to reach the annealing temperature required by the process and affect the annealing effect

Abstract

The invention discloses a copper wire annealing pot for manufacturing enameled wires, and belongs to the field of cable manufacturing equipment. The copper wire annealing pot comprises a pot body and a pot cover. A sealing ring is arranged between an upper edge opening of the pot body and the pot cover, a lower cooling ring is arranged on the lower side of the upper edge opening of the pot body, an upper cooling ring is arranged on the upper side of the pot cover, the upper cooling ring and the lower cooling ring are of hollow structures and are communicated with each other, a liquid inlet is formed in the upper cooling ring, and a liquid outlet is formed in the lower cooling ring; the pot cover is provided with a pressure gauge, an inflation pipe, a vacuumizing pipe and a temperature meter, and the temperature meter extends into the pot body. The copper wire annealing pot has the advantages that the temperature meter is mounted in the copper wire annealing pot, so that the internal temperature of the copper wire annealing pot can be controlled in real time in heating procedures, and influence of temperature difference between the copper wire annealing pot and an electric pot on annealing effects can be prevented; the upper cooling ring and the lower cooling ring can be filled with cooling liquid, so that the pot cover can be cyclically cooled, and the sealing performance of the copper wire annealing pot and the annealing effects can be guaranteed. The invention further discloses an annealing method implemented by the aid of the copper wire annealing pot.

Description

technical field [0001] The invention relates to an annealing tank and an annealing method, in particular to a copper wire annealing tank and an annealing method for enameled wire production, belonging to the field of cable production equipment. Background technique [0002] Annealing is a necessary process in the production process of enameled wire. The purpose of annealing is to make the copper wire hardened due to the lattice change during the mold stretching process heated at a certain temperature, so that the molecular lattice can be rearranged and restored to the requirements of the process. At the same time, it removes the residual lubricant and oil on the surface of the copper wire during the stretching process, making the copper wire easy to paint and ensuring the quality of the enameled wire. At present, in the process of coil annealing, the coiled hard bare copper wire is usually put into an annealing tank and then placed in an electric furnace for heating, anneali...
