[0016] The present invention proposes an electroplastic drawing strengthening process of high carbon steel wire by using electroplastic wire drawing technology to improve the performance of high carbon steel wire. The process steps of the electroplastic drawing of high carbon steel wire are as follows:
[0017] 1) Electroplastic drawing device: a DC pulse current generator using the principle of capacitor charging and discharging, connects the output end of the pulse power supply to the steel wire in the deformation zone of the steel wire, that is, the two ends of the mold and the steel wire. It adopts artificial floating design and contact connection. Ensure the absolute safety of operators.
[0018] 2) According to the requirements of steel wire products, select process parameters such as output voltage, amplitude current, pulse frequency, pulse width, and deformation parameters such as deformation amount and deformation speed, so as to improve the tensile strength and surface q...
