An engineering analytical approach to the design of cold wire drawing processes for strain-hardening materials

摘要

Improved analytical solutions developed to design and optimize cold wire drawing processes are proposed. They account for strain-hardening, which could be accounted for, in the equations usually adopted in the engineering practice, only in a semi-empirical way. All the new proposed solutions can be expressed in terms of the coefficient of friction between the wire and the die, thus avoiding the need to calibrate physically meaningless coefficients as was necessary for the previous literature solutions. The effectiveness of the proposed results is demonstrated by comparison with existing experimental results.
