[Case Study of the Molding Process] Analysis of Hole Expansion Processing Using JSTAMP
Check the FLD (Forming Limit Diagram)! It is predicted that cracks are likely to occur near the edges of the holes indicated in red!
We would like to introduce a case study where a blank with a hole was processed using cylindrical drawing, and an analysis was conducted to widen the hole. The die stroke speed was set to 6000 mm/s, the load on Holder 1 was 1200 N, and the load on Holder 2 was 600 N, with the FLD (Forming Limit Diagram) being checked. As a result, it was found that the deformation state of the blank was close to uniaxial tension according to the FLD. Additionally, it is anticipated that cracks are likely to occur near the edge of the hole indicated in red. 【Model Overview】 ■ Die stroke speed: 6000 mm/s ■ Load on Holder 1: 1200 N ■ Load on Holder 2: 600 N *For more details, please refer to the related links or feel free to contact us.
