Mechanical and Laser Micro Deep Drawing

Key Engineering Materials, 2007
Mechanical micro deep drawing becomes a more and more industrial relevant process. But due to size effects new challenges are involved in this process compared to macro deep drawing. The size effects cause an increase of friction and thus hinder the material flow.

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.

Deep Drawing and Stretch Forming

1976
Deep-drawing and stretch-forming processes make up a considerable proportion of metal-forming operations, and have deservedly received much attention. Although they are often thought of as mutually complementary, we should remember that whereas stretch forming may well be decisive in the success or failure of a deep-drawing process as a whole, it is an

An Oscillatory Deep-Drawing Analogue

1975
Consideration is given to the application of ultrasonic vibration ot the deep-drawing process. It is argued that from an understanding of the mechanics of cup-drawing, excitation of the die in a radial mode is likely to yield greatest benefit.

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 ...

A method for estimating the limiting drawing ratio in deep-drawing

International Journal of Production Research, 1974
The new method of estimating the Limiting Drawing Ratio (L.D.R.) in deep-drawing makes use of oversize blanks with standard diameters. Experimental results indicate that the bulge depth at fracture, to blank diameter curves for oversize blanks can be expressed by a particular type of an exponential expression. To evaluate the parameters in the equation,

Hot deep drawing of titanium sheet

Materials Science and Technology, 1991
AbstractCommercial purity titanium (IMI 125) and a Ti–Cu alloy (IMI 230) in sheet form have been deep drawn at room temperature and at elevated temperatures. Cylindrical cups drawn at room temperature and at temperatures up to about 550°C develop four ear peaks at about 45° to the rolling direction (RD).
