Study of Perforated Sheet (Light Weight Metal Sheet)

We are also trying reduced the weight of perforated sheet by making groove, holes, cuts, chamfer & fillet on perforated sheet. We check other parameters of perforated sheet like velocity, stress on cut, groove work piece thickness, shape of perforation and pitch of perforation. For reducing the wrinkling effect on product, we try to modify the parameter like velocity of punch, diameter of die and punch, clearance between punch and die, BHF. The earring effect in formed part reduces by using 3D modeling and analysis. We go to reduce weight for increase power to weight in automobile industries. We complies that objective by change in parameter of perforation operation like different shape of punch and die, change the velocity of punch, different BHF, etc. then we will collect data of different perforated sheet. The data show weight and strength of material. From data we can choose suitable material for automobile industries. Detailed investigations, including experimental tension tests, were performed also to analyze the local deformation of the subject sheet metal, and the validity of the proposed yield criterion. The current design and analyses can help the optimization of the control scheme of drawing processes rather than using the conventional designs. A comparison of the predicted and experimental results showed good agreement.
