Description

Technical Field

[0001] The utility model belongs to the technical field of metal annealing, and particularly relates to a copper wire annealing mechanism. Background Art

[0002] Annealing is a metal heat treatment process, which means heating the metal slowly to a certain temperature, maintaining for a sufficient time, and then cooling at an appropriate speed. It can reduce hardness, improve machinability; reduce residual stress, stabilize dimensions, reduce deformation and crack tendency; refine grains, adjust the structure, and eliminate structural defects. Copper wires are usually drawn from hot-rolled copper bars. At this time, the copper wires have defects such as internal residual stress, uneven grain structure, and excessive surface hardness, and need to be annealed to improve. The copper wires are slowly heated to a certain temperature, maintained for a sufficient time, and then cooled at an appropriate speed.

[0003] The Chinese patent with the comparative announcement number CN218262605U discloses a copper wire annealing mechanism, which includes a base. An annealing box is fixedly installed on the top of the base. The annealing box includes a first chamber, a second chamber, and a third chamber. An electric heating tube is arranged in the middle of the first chamber, a wind cooling mechanism is arranged in the middle of the second chamber, and atomizing spray heads are symmetrically and fixedly arranged on the top of the third chamber; a first support and a second support are also symmetrically and fixedly installed on the top. A first roller shaft is rotatably installed on the first support, a second roller shaft is rotatably installed on the second support. A copper wire of a predetermined length is wound on the first roller shaft, and the copper wire led out from the first roller shaft is wound to the second roller shaft. A gear drive mechanism is drivingly connected to the second roller shaft, and the gear drive mechanism is used to drive the second roller shaft to rotate intermittently. The rotation of the second roller shaft causes the copper wire on the first roller shaft to sequentially pass through the middle parts of the first chamber, the second chamber, and the third chamber.

[0004] However, the above patent uses atomized spraying of coolant to cool the copper wire in a liquid state, resulting in insufficient comprehensive contact between the coolant and the copper wire, and oxidation spots may be generated on the surface of the copper wire, affecting the annealing quality. Moreover, it can only anneal a single copper wire, and the processing speed is relatively slow. Therefore, a new device needs to be designed. Content of the Utility Model
