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

Performance evaluation of bio-lubricants in strip drawing and deep drawing of an aluminium alloy
Advances in Materials and Processing Technologies, 2020With the increasing awareness and concerns towards the detrimental impact of mineral-oil-based lubricants, a step forward is crucial to replace them with benign environment-friendly lubricants.

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.

Deep drawing of fiber metal laminates for automotive lightweight structures
Composite structures, 2019Current challenges in the automotive industry are the reduction of fuel consumption and the CO2 emissions of future car generations. These aims can be achieved by reducing the weight of the car, which further improves the driving dynamics.

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.

Simultaneous deep drawing and cold forging of multi-material components: Draw-forging
CIRP annals, 2019A new process combining cold forging and deep drawing is introduced for forming multi-material components. The components consist of a cold extruded core with a deep drawn and redrawn cup acting as shell.
