Ladd – Laser Assisted Deep Drawing
نویسندگان
چکیده
In the current work, cup drawing experiments with laser assistance are presented where only selected areas of the work piece have been heated up. Since the strongest deformations occur at the outer circumference of the blank, only that area has been heated up by a defocused laser beam. Selective laser heating of the work pieces was performed by diode as well as Nd:YAG laser radiation. The forming load for the experiments was established by a small hydraulic press with a maximum drawing force of 630kN and a hydraulic die cushion. During the experiments, the drawing path and all relevant forces have been recorded. Experimental results clearly demonstrate that this combined laser forming process is enlarging the possibilities of conventional deep drawing.

Laser Assisted Forming – a Valuable Extension of the Limits of Metal Shaping
During the plastic deformation of brittle materials as magnesium, titanium or high strength steels, for instance in bending of sheet metals, the local strain can exceed the ductility – the strain at rupture – and thus cracks appear that eventually lead to rupture. Hot working would be beneficial since a temperature of a few hundred centigrades leads to an increase of the ductility by more than ...
متن کاملForming Behaviour in Laser Shock Drawing
Through the continuing trend of miniaturization new cost efficient and fast methods for processing small parts are required. In this paper a new non-mechanical process for the forming process of micro deep drawing is presented. This new deep drawing process utilizes a laser initiated plasma shock wave at the target, which forms the sheet. Several pulses can be applied at one point and therefore...
متن کاملNumerical and Experimental Research of Deep Drawing Process
There are mainly two methods of deep drawing analysis; experimental and analytical/numerical. Experimental analysis can be useful in analyzing the process to determine the process parameters that produce a defect free product, and the analytical/numerical modeling can be used to model and analyze the process through all stages of deformation. This approach is less time consuming and more econom...
متن کاملOptimization of parameters of Anti lock Braking System for use in deep drawing
A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...
متن کاملThe Effect of Ridges to Improve Ductility and Reduce Deformation Energy in Deep-Drawing Process
In this research, two new methods that improve the drawing depth of deep-drawing processes have been introduced. In the first technique, by creating ridges on the punch surface, the stress concentration is decreased on the blank near the punch edge, in turn increasing the drawing depth. The second method is based on the principle of reducing resistant force in the flange area between the die, t...
