Influence of Process Parameters and Viscosity on Radial Stresses in Fluid Assisted Deep Drawing Process
Deep drawing is an important process used for producing cups from sheet metal in large quantities. The process parameters and viscosity of fluid is maintained the major role in the hydro forming-deep drawing process. Hydraulic pressure can enhance the capabilities of the basic deep drawing process for making metal cups. Hydraulic pressure contributes positively in several ways to the deep drawi...
متن کاملextra high limiting drawing ratio (ldr=9) cylindrical deep drawing based on finite element and experiment
deep drawing of cylindrical shapes with high limiting drawing ratio (ldr) values is relatively difficult. annealing is a further operation, which in turn adds costs and consumes significantly time to the forming process. in the present work, cylindrical cups from brass sheet were made with only limited anneal during few steps, but having ldr of 9 that is about 2 times higher than previous works...
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...
