本文的目的是从润滑机理出发，对杯形件拉深过程中的表面压扁机理进行研究。研制了一种新的拉深工艺实验装置，并用不同的润滑剂和减薄方法对铝杯进行了拉深实验。实验表明，在适当的润滑剂粘度和减薄条件下，模具表面的摩擦系数最小。也证实了在摩擦系数最小的条件下，杯体表面是最平整的。
The object of this paper is to clarity the surface flattening mechanism in the cup ironing process based on the lubricating mechanism. A new experimental apparatus for the ironing process was made and experiments on ironing were carried out with aluminum cups using various lubricants and reductions in thickness. The experiments revealed that on the die surface the friction coefficient becomes minimum under the appropriate conditions of viscosity of lubricant and reduction in thickness. It was also confirmed that the cup surface is best flattened under conditions where the minimum friction coefficient appears.
