Development of hydro-mechanical deep drawing
Journal of Materials Processing Technology, 1998 The hydro-mechanical deep-drawing process is reviewed in this article. The process principles and features are introduced and the developments of the hydro-mechanical deep-drawing process in process performances, in theory and in numerical simulation are described. The applications are summarized. Some other related hydraulic forming processes are also

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.

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

On the acting pressure in laser deep drawing
Production Engineering, 2008Through the continuing trend of miniaturization new cost efficient and fast methods for processing of small parts are required. In this paper a non-mechanical process for the forming process of micro deep drawing is presented. This new pulsed laser based deep drawing process utilizes an initiated plasma shock wave at the target, which forms the sheet ...

The term metal forming refers to a group of manufacturing methods by which the given shape of a workpiece (a solid body) is converted to another shape without change in the mass or composition of the material of the workpiece. In this paper, the basics of a deep drawing process for the production of a thick plate steam boiler end caps are shown.

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 ...

Deep drawing of superplastic material
Metals Technology, 1976AbstractA 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.
