拉丝模具的冷却对模具寿命及钢丝性能的影响

Effect of Wire Drawing Die Cooling on Die′s Service Life and Steel Wire Property

从拉丝模的冷却不足对润滑、模具寿命及钢丝性能的影响进行了分析,并提出了改进措施:一是模套与模芯之间的过盈量选择要合适;二是在保证足够预紧力的情况下减小模套的厚度;三是要对模具进行强制冷却。

To analyze the effect of absent cooling of wire drawing die on lubrication, die＇s service life and steel wire property, and improvement measures are put forward： first is suitable surplus quantity selection between die sheath and die core, second is to decrease the thickness of die sheath under condition of guaranteeing full of pre-tensile, the third is to force cooling for wire drawing die.
