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 ...

Hybrid deep drawing tool for lubricant free deep drawing
AIP Conference Proceedings, 2017This paper presents a concept for a hybrid deep drawing tool based on polymer concrete and first results from actual deep drawing tests using a prototype of the newly developed tool. The hybrid tool presented here has a defined macro-structure of the blankholder and drawing die as implemented before by Brosius et al. [1] in a steel tool for a lubricant

The optimisation deep-draw clearance design for deep-draw dies
The International Journal of Advanced Manufacturing Technology, 1998In this paper, the modelling of deep-drawing processing using neural networks is established. The relationships between process parameter (material thickness, punch diameter, die-cavity diameter and materials-clearance ratio) and deep-drawing performance (the dimensional error of diameter and cylinder) are created, based on a neural network.

Abstract By deep-drawing into a high-pressure fluid the limiting drawing ratio can be considerably increased over that obtained in conventional deep-drawing. However, this result is achieved at the cost of greater expenditure of energy and of some form of control system for the high-pressure fluid.

An analysis, based on the energetic stability criterion combined with numerical calculations, for the hydraulic drawing of tapered cylindrical cups is developed in this paper. As the calculation shows, the limiting drawing ratio strongly depends on the pressure during hydraulic drawing. The theoretical and experimental results agree wall.

Abstract This article illustrates the mechanics of the deep drawing of a cylindrical cup. It discusses the fundamentals of drawing and drawability. Sheet metal is drawn in either hydraulic or mechanical presses. The article summarizes the defects in drawing and factors considered in press selection for drawing.

Deep Drawing Height Analysis of Rectangular Cup Drawing
Volume 3: Design and Manufacturing, Parts A and B, 2010The deep drawing process is widely used in industry because it allows the production of parts with reduced weight and good mechanical properties. However, the deep drawing process of non-cylindrical shapes still relies on experimental and trial and error methods, leading to high costs and long development times.

Process optimisation in deep drawing
Revue Européenne des Éléments Finis, 2000Summary: We propose a numerical technique for process optimization applied to the deep drawing of sheet metals. This technique is based on the combination of an optimization algorithm and finite element method. The optimization algorithm is based on the gradient method and on the sensitivity analysis, and allows to optimize process parameters in order ...
