  • Use of variable blank holder force for avoiding wrinkles at all stages of forming processes
    Volk, Mihael, 1984- ...
    In the sheet metal forming many different problems can occur. One of the most problematic is the wrinkling of the sheet metal during the deep-drawing process. This studied FEM analysis of an ... industrial application from household appliances was carried out and then calibrated with the real results.Due to the very problematic technological issues in the study, new flexible holding system with segments was developed and used. In the flexible holding system, the distributed blank holder forces (BHF) can be used and the time variable BHF can eliminate wrinkling during the deep drawing process. By using this approach, the technological window is bigger and the process is more stable.
