Investigation of the Effects of Pressure Path and Tool Parameters in Hydrodynamic Deep Drawing
In recent years, hydroforming process has been applied in different industries such as aerospace, automotive and military industries due to its advantages, such as high dimensional accuracy, capability of forming complicated parts and high drawing ratio. Hydrodynamic deep drawing with radial pressure is one type of hydroforming process. In this paper, forming of cylindrical cups in hydrodynamic...
متن کاملLadd – Laser Assisted Deep Drawing
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 formi...
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 کاملThe Pressure Field in the Gas-lubricated Step Slider Bearing
Singular perturbation methods are applied to an analysis of the operation of an isothermal gas step slider bearing of narrow geometry and operating at moderate bearing numbers. Approximate expressions are obtained for the pressure field in the lubricating gap, as well as the load-carrying capacity of the bearing; and the influence of the nature of the bearing step on those quantities is investi...
