Instability Modes in Deep-Drawing

1977
Three modes of instability failure are identified for the deep-drawing of a cylindrical shell. The material properties and frictional conditions between deforming blank and tooling which determine the operative mode of instability are examined theoretically and experimentally.

AN APPRAISAL OF THE THEORY OF DEEP DRAWING

Metallurgical Reviews, 1960
AbstractThe term “deep drawing” is generally understood to apply to the process of deforming sheet metal that is characterized by the use of a punch and a die, the sheet being drawn inwards and over the die profile by the advancing punch whilst the flange is controlled by moderate “blank-holding” pressure supplied by a suitably shaped blank-holder ...

Deep Drawing with Hydrodynamic Lubrication

1984
A modified Deep Drawing process is proposed which eliminates dry friction by hydrodynamic flow. In principal, this process enables an increase in the Limit Drawing Ratio (LDR) by virtue of relaxing interfacial constrains. The fluid is enforced to lift up the blank from the die and to stream radially beneath it in a narrow gap.

Force of the deep drawing

2017
The term metal forming refers to a group of manufacturing methods by which the given shape of a workpiece (a solid body) is converted to another shape without change in the mass or composition of the material of the workpiece. In this paper, the basics of a deep drawing process for the production of a thick plate steam boiler end caps are shown.
