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 aluminum parabolic workpieces—experiments and numerical simulation

International Journal of Machine Tools and Manufacture, 2000
Aluminum parabolic workpieces were formed with hydromechanical deep-drawing technology. The deep-drawing process was analyzed by using the explicit finite element method with various process parameters. Defects of wrinkling and rupture are predicted for some forming conditions, and the thickness distribution results are in good agreement with the ...

Hydromechanical Deep-Drawing of Aluminium-Alloys at Elevated Temperatures

CIRP Annals - Manufacturing Technology, 2002
Abstract This paper presents a technology that combines the different effects used in hydromechanical and warm deep drawing to reduce the drawing force and to increase the transmittable drawing force in the deep drawing process of aluminium sheets by flange heating and by using a counter pressure.

Hydromechanical deep drawing

Scandinavian Journal of Metallurgy, 2000
An experimental investigation on the control of process parameters for the hydromechanical deep drawing of mild steel and an aluminium alloy with special attention to control of the blank holder force (BHF) is carried out. The effect of the counter pressure in the hydromechanical deep drawing process is investigated in combination with different ...

On the Scale Dependence of Micro Hydromechanical Deep Drawing

Key Engineering Materials, 2016
Tooling 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 of superalloy cups

Journal of Materials Processing Technology, 2005
Abstract As an advanced technology of sheet metal forming, hydromechanical deep drawing (HDD) is being used increasingly in the sheet metal forming of common materials like aluminum, copper and steel. For superalloys widely applied in aviation and spaceflight, study is deficient at present. In this paper, the forming conditions of cylindrical cups of

Hydromechanical Deep Drawing with Uniform Pressure on the Flange

CIRP Annals, 2000
Abstract 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 ...

Hydromechanical Deep Drawing of Tailor Welded Blanks

steel research international, 2005
This 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.

The limit drawing ratio in die angled hydromechanical deep drawing method

The International Journal of Advanced Manufacturing Technology, 2019
In the study, the effect of die angle, die radius, die punch, blank holder force, and chamber pressure parameters on the limit drawing ratio (LDR) in die angled hydromechanical deep drawing process was investigated by using Taguchi experimental design method.
