讨论了金属板料与模具接触表面上的“边界摩擦”状态，提出了应根据不同的材质、变形方式及程度等采用不同的润滑剂配方，并阐述了润滑剂各主要组分在冲压加工中的作用。研究了广泛应用于板料加工中的湿膜润滑剂的成膜原理。介绍了自制的分别应用于不锈钢薄板深、浅拉深成形的两种水基润滑剂。 The state of “boundary friction” on the contact surface between the metal sheet and the mold is discussed. It is suggested that different lubricant formulations should be adopted according to different materials, deformation methods and degree, and the main components of the lubricant in the stamping process Role. The film forming principle of wet film lubricant which is widely used in sheet metal processing is studied. Two kinds of self-made water-based lubricants, which are applied to deep and shallow deep-drawn stainless steel sheets, are introduced respectively.
