|
The drawing wrinkling of 125 motorcycle tank bottom shell is often met in stamping test.The drawing wrinkling of 125 motorcycle tank bottom shell was simulated by the eta/Dynaform software.Based on the stress and strain analysis on simulation results,the wrinkling reasons were studied and the wrinkling solution was brought up.From the simulation results,the main reason of wrinkling is that the stress component is not balancing in the process of blank forming.By using the scheme of two pieces in one die,stress distribution on the part opening was balanced effectively.At the same time,by increasing blank holder force,changing friction coefficient,setting draw-bead and changing blank size,the drawing wrinkling in stamping test was basically eliminated.
