Abstract

This paper presents a wear analysis of tungsten carbide drawing dies in the process of steel wire drawing. The finite element method (FEM) analysis showed a significant correlation between drawing die geometry, single reduction size and drawing speed on the rate of drawing die wear. It has been shown that in steel wire drawing at higher drawing speeds, intense heating of the drawing die occurs due to friction at the wire/drawing die interface, leading to premature wear. Tribological tests on the material for the drawing die cores (94%WC+6%Co) confirmed the gradual abrasion of the steel and carbide sample surfaces with the "products" of abrasion sticking to their surfaces. The increase in temperature increases the coefficient of friction, translating into accelerated wear of the drawing dies.

摘要

本文介绍了碳化钨拉丝模在钢丝拉拔过程中的磨损分析。有限元方法（FEM）分析表明，拉丝模几何形状、单次减径尺寸和拉拔速度与拉丝模磨损率之间存在显著相关性。结果表明，在较高拉拔速度的钢丝拉拔过程中，由于钢丝/拉丝模界面处的摩擦，拉丝模会发生剧烈发热，导致过早磨损。对拉丝模芯材料（94%WC+6%Co）进行的摩擦学测试证实，钢和硬质合金样品表面会逐渐磨损，磨损“产物”会附着在其表面。温度升高会增加摩擦系数，进而导致拉丝模加速磨损。
