摘要

为了获得激光清洗轮胎模具的工艺参量, 采用自主研制的平均功率达250W的脉冲式YAG激光清洗设备开展了轮胎模具激光清洗实验研究。取得了不同激光参量对轮胎模具清洗效果的实验数据, 并研究了激光峰值功率、能量密度等参量与轮胎模具清洗速度、清洗效果的关系。结果表明, 清洗轮胎模具脉冲YAG激光比CO2激光更高效; 轮胎模具清洗的激光能量密度阈值约为250mJ/mm2, 提高激光峰值功率和平均功率能提高清洗速度和清洁效果。此结果为激光清洗设备的研究提供了参考。

Abstract

In order to obtain technological parameters for cleaning tire molds with laser, a self-developed pulse YAG laser with the average power of 250W was used to carry out experiment of tire mold cleaning. The experimental data of the relationship between different laser parameters and the cleaning effect of the tire mold was obtained. The relationships between the parameters such as laser peak power, energy density and cleaning speed, cleaning effect of the tire mold were studied. The results show that for cleaning tire molds, pulse YAG laser is more efficient than CO2 laser. Laser energy density threshold for cleaning tire molds is about 250mJ/mm2. The increase of laser peak power and average power can improve cleaning speeds and cleaning effect. The research provides the reference for research of laser cleaning equipment in this field.
