摘要：

铝合金热冲压是实现汽车轻量化目标的重要制造手段，生产过程中的摩擦磨损造成的板料擦伤和开裂是批量生产的主要阻碍。为了研究热冲压过程中润滑剂的适用性和润滑机理。基于此，基于销-盘摩擦实验设备，通过合理的实验设计模拟了热冲压的实验工况，选用了一种使用工况接近的水基脱模剂进行摩擦实验，并评价其在热冲压工况下的润滑性能，探究其润滑机理。通过实验发现,水基硅氧烷润滑剂能够通过隔绝模具与工件直接接触，获得较长时间的低摩擦因数状态。利用水基润滑剂实现铝合金热冲压过程中的稳定低摩擦因数状态是可行的。

Hot stamping of aluminum alloy is an important manufacturing method to achieve the goal of automobile lightweight, and scratches and cracks of sheets caused by friction and wear in the production process are the main obstacles to mass production. In order to study the applicability and lubrication mechanism of lubricants in hot stamping process, based on the pin-disk friction experimental equipment, the experimental conditions of hot stamping were studied by reasonable experimental design, and a water-based release agent with similar working condition was selected for friction experiment to evaluate its lubrication performance under the hot stamping condition and explore its lubrication mechanism. Furthermore, through experiments, it is found that the water-based siloxane lubricant could obtain a long time low friction factor state by isolating the die from the workpiece. So it is feasible to use water-based lubricant to achieve stable and low friction factor state in hot stamping process of aluminum alloy.
