Numerical prediction of limiting draw ratio and thickness variation in hydromechanical deep drawing
International Journal of Materials and Product Technology, 2004Hydromechanical deep drawing is a process for producing cup shaped parts with the assistance of a pressurised fluid. In the present work, a complete experimental set up has been designed and fabricated to conduct hydromechanical deep drawing on a 315 tonne hydraulic press.

Hydromechanical Deep-Drawing of Fuel Tanks
SAE Technical Paper Series, 2000<div class="htmlview paragraph">Deep-drawing with hydraulic counter pressure presents numerous advantages compared to conventional deep-drawing. Hydromechanical deep-drawing is a capable process for producing complicated and tapered-shaped stamping parts as well as parts which require excellent surface quality, i.e. outer body panels.

Hydromechanical Deep Drawing of Tailor Welded Blanks
steel research international, 2005This paper investigates the conventional and hydromechanical deep drawing of circular tailor welded blanks (TWBs) with a linear weld line. TWBs offer the possibility to combine different materials, different thicknesses and different coatings within one part, as to optimally fit the applied loads with the lowest possible weight.

On the Scale Dependence of Micro Hydromechanical Deep Drawing
Key Engineering Materials, 2016Tooling feature size to minimum thickness becomes small in micro scale products and its ratio affects the deformation behavior in micro sheet forming significantly. In this study, the effect of this relative tooling feature size on drawing characteristics and effects to improve the drawability, such as friction holding effect, hydrodynamic lubrication ...

Hydromechanical Deep Drawing with Uniform Pressure on the Flange
CIRP Annals, 2000Abstract Conventional hydromechanical deep drawing is difficult to simulate due to difficulties regarding the determination of the pressure distribution on the flange when a leak flow occurs between the draw die and the flange. To avoid this problem the hydromechanical deep drawing process has been modified in such a way, that the pressure on the ...

Blank shape optimization in sheet metal Hydromechanical Deep Drawing (HDD)
International Journal of Material Forming, 2010In order to perform a successful sheet metal forming operation and to avoid shape deviations and tearing and wrinkling defects, process and material variables, such as tools geometry, blankholder force, friction, blank shape, sheet thickness and material properties, should be optimized.
