Evaluation of draw beads influence on intricate shape stamping drawing process.
Original language description
Paper concerns evaluation of influence of shape, size and location of rectangular and semicircular draw beads on sheet-metal forming process. For analysis the simulations of forming process of selected two types of intricate shape stampings with similarground plan and with approximately the same height from steel strip DC04 with the use of models of optimal blanks made by BSE (Blank Size Engineering) modul of simulation program Dynaform 5.7 were carried out. From simulations of forming process in simulation program Dynaform 5.7 followed that the most suitable is drawing without use of draw beads because cracks in stamping bottom corners do not arise. In the case of undesirable secondary waviness in the walls of intricate shape stamping the drawing with draw beads could be used but it would be necessary to increase the radius at the bottom of both stampings alternatively to choose another material with higher formability.
