Improving the quality of deep drawn parts using variable blank holder force
Source abstract
Abstract
A new tool design concept for deep drawing is presented. The design features a hydraulic shimming system providing a variable blank holder force (BHF). An objective function describing the geometric quality of the drawn part and the process stability is formulated. The objective function is used in a gradient based optimization scheme to find a set of optimal loads for the drawing of a square bar sink. It is shown that a variable BHF can increase the process robustness to changes in process parameters compared to a constant BHF.
