ABSTRACT:
In the wall ironing of a deep-drawn cylindrical body, two ironing ring die regions provide respectively immediately successive first and second thickness reduction phases which take place simultaneously with a relatively small reduction occurring in the first phase and a relatively large reduction occurring in the second phase. Lubricant is applied to the outer surface of the body via inlet between the two die regions. To achieve a high mount of reduction with low applied force, the annular space bounded by the contact regions of the body with said two die regions and the portion of the body located between said two contact regions is fluid-tightly sealed, apart from inlet or inlets for said lubricant, and said space is so shaped and the lubricant is applied through said inlet or inlets at such a pressure that at the second die region hydrodynamic lubrication of the body and die region is achieved.
