【Abstract】 model for calculating constraints of the drawing rib has been established by means of basic Linit simulation experiments on the drawing rib,by studies on the internal deformation of the rib of the plate material,on the effects of edge pressure and geometrical parameters of the rib on the constraints of drawing rib,on the law of constraint variation of the drawing rib with the changes of the wrap angle of the die set and on the deformation of the plate material due to over drawing of the rib.更多还原
