Metal skin stretch forming lubricating oil performance evaluation method

The invention belongs to the technical field of sheet metal part forming and manufacturing, and particularly relates to a metal skin stretch forming lubricating oil performance evaluation method. According to the method, the problem of evaluating the performance of the aluminum alloy Monte Ray lubricating oil is effectively solved, and a simple and effective method is provided for selecting suitable lubricating oil; the efficiency of the single-curvature mold parallel tensile test method is higher than that of multiple times of single-piece stretching, and evaluation deviation caused by poor equipment process stability can be avoided. 本发明属于钣金件成形制造技术领域，特别是涉及一种金属蒙皮拉伸成形润滑油性能评估方法。本发明有效解决了铝合金蒙拉润滑油性能优劣的测评问题，对选择一款适合的润滑油提供了简单、有效的方法；使用单曲度模具并列拉伸试验的方法比多次单件拉伸的效率更高，且可避免因为设备工艺稳定性差而带来的评估偏差。
