Effect of Die Design Parameters on Thinning of Sheet Metal in the Deep ...
Geometry of drawing die assembly Due to the symmetry, the numerical analysis of the deep-drawing process was performed by using only one quarter of 3D numerical model to reduce the computational time. The model is shown in Figure 3. Discrete rigid form was used to model the punch, die and holder, whose motion was governed by the motion of a single node, known as …
Deep Drawing from A to Z | MetalForming Magazine Article
In contrast, the objective of a deep-drawing operation is to flow sheetmetal into a die cavity to produce the required shape with minimal material stretching and thinning. Deep Drawing Explained: The Basics. Deep drawing produces a part from a flat blank via the action of a punch force onto the blank. That force pulls (draws) the blank into a ...
Deep Drawing Process for Sheet Metal

A novel deep drawing process for aluminum alloy sheets at …
Some special deep drawing processes at elevated temperatures have been adopted to improve the deep drawability of aluminum alloys, and include warm deep drawing and hot deep drawing. The warm deep drawing of circular AA5754-O blanks was performed with Swift cupping tests (Laurent et al., 2015), and it was found that the drawability of the alloy …
Deep drawing: Key design principles & tips for …
If the square drawn shell is too tall to be drawn in a single operation, it must undergo a draw reduction. As with round draws, all material necessary to make the final part must be present in the first draw. Draw …
Inhibition of adhesive wear in tantalum cup deep drawing by …
The tantalum shell of capacitor is usually obtained by deep drawing process, and adhesive wear of the shell is the main hidden danger during its deep drawing process. In this paper, ultrasonic ...

Deep Drawing
The deep drawing process variables include the drawing ratio, the profile radii of the die and the punch, the clearance between the punch and the die opening, the drawing speed, the friction and lubrication, and the type of restraint of metal flow used (if any), such as the force applied by the pressure ring. The material parameters are sheet thickness and anisotropy.
