Description

Technical Field

[0002] The copper alloy flat fine wire is rapidly cooled after annealing in order to optimize its microstructure and improve its mechanical properties and electrical conductivity. The crystal structure of copper alloy is mainly face-centered cubic. The annealing process can adjust the crystal structure by heating the material and controlling the cooling rate. Rapid cooling causes the grains to become finer, which helps to improve the strength, hardness and wear resistance of the material, reduce internal stress and deformation energy, and thus improve its plasticity and electrical conductivity. This process ensures the excellent performance of the copper alloy flat fine wire under high stress and deformation conditions by optimizing the grain boundaries and grain distribution; such as a waterless annealing mechanism disclosed in the authorization announcement number CN210657016U, including a box body, the front of the box body is fixedly connected to a cooling box, a first fixed pulley and a second fixed pulley, the front of the box body is rotatably connected to a rotating shaft, one end of the rotating shaft passes through the front of the box body and extends to the inner cavity of the box body, the waterless annealing mechanism controls the mercury slip ring to heat up through the annealing power supply, and transfers the heat to the annealing copper wheel, the flat wire after rolling passes through the cycloid device into the annealing copper wheel for heating treatment, After heating, it is introduced into a cooling box and cooled by the cold inert gas inside the cooling box, which increases the ductility of the flat wire and improves the surface quality of the flat wire. The above technical scheme mainly uses the low-temperature cold inert gas in the cooling box to cool down and exchange heat for the flat wire. However, during the routing process of the copper alloy flat fine wire, the copper alloy flat fine wire is prone to vibration of the annealing equipment, uneven tension or unevenness of the material itself, resulting in jumping and deviation during routing, resulting in differences in the contact between the copper alloy flat fine wire body and the cold source. At this time, the internal crystal structure of the copper alloy flat fine wire is uneven or over-annealed, affecting the mechanical properties and conductive properties of the material.

[0020] The front auxiliary wiring structure includes an axle seat 201 fixed on the outer wall of one side of the U-shaped axle frame 2 and a lower longitudinal axis 202 rotatably installed inside the axle seat 201, and an I-shaped wheel 203 is fixed on the surface of the lower longitudinal axis 202. The upper auxiliary wiring structure 4 includes an upper longitudinal axis 401 fixed at one end of the U-shaped axle frame 2 and a grooved wheel 402 rotatably installed on the surface of the upper longitudinal axis 401. The height of the grooved wheel 402 is higher than that of the I-shaped wheel 203. The copper alloy flat fine wire is initially set on the I-shaped wheel 203, and the end of the copper alloy flat fine wire passes between the steel wheel 303 and the grooved wheel 402. The steel wheel 303 and the grooved wheel 402 are mainly responsible for guiding the copper alloy flat fine wire into the cooling channel 6, ensuring that the wire can be correctly aligned when entering the cooling system to prevent the wire from affecting the subsequent process due to offset;

During this process, the fine wire feeding mechanism 3 and the upper auxiliary wiring structure 4 can effectively guide and support the copper alloy flat fine wire and provide a conveying force for the copper alloy flat fine wire, and the cooling channel 6 is used to reduce the deflection and shaking of the copper alloy flat fine wire in the horizontal direction and support the copper alloy flat fine wire to prevent the fine wire from changing due to tension. Or the horizontal deviation caused by the vibration of the annealing equipment, then the staff starts the lifting and anti-jumping mechanism 5 to work, and the lifting and anti-jumping mechanism 5 is actuated. The lifting and anti-jumping mechanism 5 is specially designed to limit and control the vertical jump problem of the copper alloy flat refined wire, and adjust the position of the copper alloy flat refined wire to prevent the vertical jump caused by its own weight or cooling stress changes during the cooling process.
