The deep drawing is a process for shaping flat sheets into cup-shaped articles without failure or excessive localized thinning. The design and control of a deep drawing process depends not only on the material, but also on the condition of the tool material interface, the mechanics of plastic deformation, the equipment used, and the control of metal flow. The equipment and tooling parameters th...
متن کاملAnalysis of Optimization of Blank Holding Force In Deep Drawing By Using LS DYNA
Sheet metal forming problems are typical in nature since they involve geometry, boundary and material non-linearity. Cup drawings involves many parameters like punch and die radius, clearance, lubrication, blank holding force and its trajectories etc. So designing the tools for cup drawing involves a lot of trial and error procedure. To reduce number of costly trial error steps, the process can...
متن کاملThe Study of Deep Drawing of Brass-steel Laminated Sheet Composite Using Taguchi Method
Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...
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...
متن کاملNumerical Simulation of Hydro-mechanical Deep Drawing - A Study on the Effect of Process Parameters on Drawability and Thickness Variation
Hydro-mechanical deep drawing is a process for producing cup shaped parts with the assistance of a pressurized fluid. In the present work, numerical simulation of the conventional and counter pressure deep drawing processes has been done with the help of a finite element method based software. Simulation results were analyzed to study the improvement in drawability by using hydro-mechanical pro...
