Abstract

The invention provides a shear processing technology of aging precipitation strengthening type copper alloy wire and profile material, which belongs to the field of material processing and includes the following steps: Step 1, preparing materials; taking aging precipitation strengthening type copper alloy blanks, no longer undergoing solid solution Processing; step 2, shear plastic processing; input into a continuous extruder for single or multiple continuous extrusion; step 3, reducing plastic processing; processing the material after shear plastic processing into a wire of suitable cross-section or diameter , profiles; step 4, aging heat treatment; aging heat treatment is carried out to the wires and profiles after the reduction plastic processing, to improve their electrical conductivity; step 5, finishing and sizing; rolling, forging or Stretch processing to make its cross-sectional size or diameter reach the target value. The invention does not require solid solution treatment, shortens the preparation process, solves technical problems such as uneven solution temperature, difficult realization of rapid quenching by solution treatment, and the fluctuation of material properties caused thereby.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a shearing processing technology for aging precipitation strengthening type copper alloy wire and type material. Background technique [0002] Chromium-zirconium copper (CuCrZr) chemical composition (mass fraction) % (Cr: 0.05-1.5, Zr: 0.02-0.4) hardness ≥ 78HRB, conductivity ≥ 43ms / m. Chromium-zirconium copper has high strength and hardness, good electrical and thermal conductivity, good wear resistance and wear reduction, after aging treatment, the hardness, strength, electrical conductivity and thermal conductivity are all significantly improved, and it is easy to weld. Widely used in motor commutators, spot welders, seam welders, electrodes for butt welders, and other parts that require strength, hardness, conductivity, and pad guidance at high temperatures. And its most frequently used forms are line and type. [0003] The traditional chromium zirconium copper processing...
