Analysis of the hydromechanical deep drawing of cylindrical cups

Journal of Materials Processing Technology, 2000
The hydromechanical deep drawing process of aluminum cups and mild steel cups is analyzed experimentally and numerically. The effects of the process parameters on the final product quality are discussed. A working zone with a suitable maximum chamber pressure is obtained from the experimental results.

Forming Limits in Hydromechanical Deep Drawing

CIRP Annals - Manufacturing Technology, 1994
Summary A systematic approach predicting the possibility of forming complex shapes in hydromechanical deep drawing has been developed The method is based on knowledge about the limiting curve of drawing-in of the flange caused by fracture, adopting different initial drawing ratios, when drawing circular cylindrical cups. This limiting curve is called

Deep drawing using a novel hydromechanical tooling

International Journal of Machine Tools and Manufacture, 2009
Abstract A new type of passive-pressurized hydromechanical deep-drawing (PHDD) tooling with two pistons is designed and manufactured: one piston installed inside is used to enhance the die pressure, the other is used to promote the radial-pushing pressure, which provides the radial-pushing and blank-holder forces. The advantage of the PHDD tooling is

Hydromechanical deep drawing of cups with stepped geometries

Journal of Materials Processing Technology, 2008
Abstract This paper deals with the hydromechanical deep drawing of metal cups with complex stepped geometries. Two materials, a low-carbon steel (DC04) and stainless steel (DIN 1.4301), have been researched. A die set with a maximum possible deep drawing ratio β 0,max  = 3.0 for a punch diameter ∅ 100 mm has been designed and constructed. The die

Die Concepts for Hydromechanical Deep Drawing

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">Deep drawing with hydraulic counter pressure has numerous advantages compared to conventional deep drawing. Hydromechanical deep drawing is a capable process for producing complex and tapered-shaped stamping parts as well as parts with excellent surface quality, i.e., outer body panels. Due to the low costs of dies,
