摘要 采用数值模拟和实验方法研究薄壁、多筋AZ31镁合金挤压型材的温热张力绕弯成形工艺,分析工艺参数对AZ31弯曲型材回弹特征的影响。结果表明:当成形温度由100℃升高至200℃时,AZ31镁合金型材弯曲件回弹角的实验值和模拟值均减小,实验回弹角由11.6°降低至10.7°,回弹率由11.26%降低至10.39%,回弹角与成形温度的关系近似为线性关系。当弯曲角由100°增加至110°时,AZ31镁合金型材弯曲件回弹角的实验值和模拟值都增加,实验回弹角由10.8°增加至11.5°,回弹率由10.48%增加至11.16%。当预拉伸量由0.2%增加至1.1%时,AZ31镁合金型材弯曲件回弹角的实验值和模拟值都减小,实验回弹角由12.5°降低至9.8°,回弹率由12.14%降低至9.51%。 采用数值模拟和实验方法研究薄壁、多筋AZ31镁合金挤压型材的温热张力绕弯成形工艺,分析工艺参数对AZ31弯曲型材回弹特征的影响。结果表明:当成形温度由100℃升高至200℃时,AZ31镁合金型材弯曲件回弹角的实验值和模拟值均减小,实验回弹角由11.6°降低至10.7°,回弹率由11.26%降低至10.39%,回弹角与成形温度的关系近似为线性关系。当弯曲角由100°增加至110°时,AZ31镁合金型材弯曲件回弹角的实验值和模拟值都增加,实验回弹角由10.8°增加至11.5°,回弹率由10.48%增加至11.16%。当预拉伸量由0.2%增加至1.1%时,AZ31镁合金型材弯曲件回弹角的实验值和模拟值都减小,实验回弹角由12.5°降低至9.8°,回弹率由12.14%降低至9.51%。
