摘要
以硼钢和铝合金板料为工件的热成形工艺在以实现汽车轻量化和提高碰撞安全性为需求的汽车制造领域的应用广泛。然而,在热成形过程中的高温、高压强的工况下,金属板料与模具之间的摩擦磨损导致板料拉毛、模具磨损和成形偏差,进而影响生产效率。近年来的国内外研究表明,在热成形生产周期内,摩擦行为受到接触界面内涂层、表面形貌和润滑效果下降等因素的综合影响。为了力求更加准确地预测摩擦行为,面向工业应用的摩擦磨损的模拟仿真正从基于接触条件的宏观层面向考虑表面情况的介观层面推进。通过回顾近些年来热成形工艺过程中的摩擦学研究,为厘清研究方向、开展下一步研究提供借鉴。
The thermoforming process using boron steel and aluminum alloy sheet metals as workpieces has been widely used in automotive manufacturing field to realize lightweight and improve crash safety. However, under the conditions of high temperature and high pressure in the thermoforming process, the friction and wear between sheet metal and die lead to sheet metal flaring, die wear and forming deviation, which in turn affects the production efficiency. In recent years, the domestic and foreign studies show that during the production cycle of thermoforming, the friction behavior is comprehensively affected by the factors such as inner coating of contact interface, surface morphology and decline of lubrication effect. In order to predict the friction behavior more accurately, the simulation of friction and wear for industrial applications is moving from the macroscopic level based on contact conditions to the mesoscopic level considering surface conditions. Therefore, the tribological research in the themoforming process in recent years is reviewed to provide support for clarifying research direction and carrying out further research.
