Abstract：

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.
