MECHANISM OF PROCESS TRIBOLOGY AND ITS APRICATION TO PRECISION METAL FORMING

今天的工业经常需要非常薄的壁、非常光滑和光亮的金属管道和圆盘。为了提高生产率，通过金属锻造工艺对这些产品的表面精加工进行了一些尝试。了解刀具与工件之间摩擦行为的机理是非常重要的。以此为背景，将一个新的概念引入到了熨烫工艺中。通过将光滑的刀具表面复制到铝带表面上，可以产生光滑的表面和这面墙。通过实验确定了压下率和油液粘度对表面平整度的影响。通过高压下金属的大变形和刀具与工件之间的小滑移来复制光滑的刀具表面是生产这类产品的重要条件。

Industries today often require metal pipes and disks with very thin wall, very smooth and bright surface. For higher productivity, some triale have been made on surface finishing of these products by means of metal forning processes. It is quite important to understand the mechanism of friction behavior between tool and workpiece. With these points as background, a new concept was introduced to the ironing process. By replicating the smooth tool surface onto the aluminum strip surface, smooth surface and this wall could be produced. An experiment was carried out to determine the effects of reduction ratio and oil-viscosity on the surface flattening. It is very important factors to produce these products that conditoins to replicate the smooth tool surface through a large metal deformation under high pressure and small slip between the tool and the workpiece.
