Comparison between laser beam and gas tungsten arc tailored welded blanks via deep drawing
, 2021This paper aims at analyzing the deformation behavior of tailor welded blanks (TWBs), manufactured by laser beam welding (LBW) and gas tungsten arc welding (GTAW), through the deep drawing process. Dissimilar and similar steels with different thicknesses

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

Deep drawing of superplastic material [PDF]
Metals Technology, 1976 AbstractA technique of deep drawing superplastic sheet material is described in which a differential temperature between the sheet and punch is used. With super plastic ZAM, the drawability obtained with this technique is significantly greater than that obtained with conventional materials or with superplastic materials using other techniques.

The deep drawing of thermoplastics
Polymer Engineering & Science, 1977AbstractThe theory of deep drawing, which has been developed for metals, is examined critically for thermoplastics. Two special characteristics of thermoplastics, the strong orientation hardening after initial yielding and the ease of crack formation and growth, are shown to vitiate the usual correlation between the drawability of the sheet and the low

A Review on Deep Drawing Process
International Journal of Emerging Research in Management and Technology, 2018Deep Drawing (DD) process is the one in which a punch forces a flat sheet metal blank into a die cavity. DD can also be described as the process which involves conversion of flat thin sheet metal blanks into parts of desired shape. Little work is available in the applications of DD processes at elevated temperatures which is going to be a very ...

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.

Process optimisation in deep drawing
Revue Européenne des Éléments Finis, 2000ABSTRACT A numerical technique for process optimisation applied to the deep drawing of sheet metals is proposed in this paper. This technique is based on the combination of an optimisation algorithm and a finite element method. The optimisation algorithm is based on a gradient method containing a sensitivity analysis and allows to optimise process ...
