Thickness Variations

In this paper, effects of friction coefficient and tool geometry on the thickness variations of a cylindrical cup were studied. Blank is made of SPXI250 alloy sheet which was analyzed by Finite Element Method (FEM). This not been studied yet. Finite Element modeling of the deep drawing process was conducted using ABAQUS/EXPLICIT software. A set of appropriate die and punch were designed for experimental tests. The results of the simulation showed that a change in the friction coefficient of the die-blank interface leads to a significant changes in the cup thickness. Moreover, the results revealed that the influence of die nose radius on the final cup thickness variations is greater than that of the punch nose radius. The simulation results of this study were compared with the experimental results and those of the other investigators’. The comparisons of the experimental and simulation results with those of the other researchers were so satisfactory.

Material Characteristics

Earing is often undesirable in the production of deep drawn containers because it results in a nonuniform cup height. A finite element model for earring analysis is developed considering only the flange area of the sheet. It was found that the draw-in depth of the flange increases with the increase of the r value, and it remains invariable when r value is larger than 2. With the increase of the r value, the max thickness decreases and the min thickness increases. If △r>0, four earings are formed. If △r =0, the material characteristics in all the planar directions are same. The flange uniformly flows into the die cavity, no earing is formed. If △r<0, four earings are formed. The earing distribution is dominated by r0, r45 and r90. Both r and △r have much effect on the earing distribution.

Element Method

Deep drawing process, one of sheet metal forming methods, is very useful in industrial field because of its efficiency. The deep drawing process is affected by many material and process parameters, such as the strain-hardening exponent, plastic strain ratio, anisotropic property of blank, friction and lubrication, blank holder force, presence of drawbeads, the profile radius of die and punch, etc. In this paper, a finite element method is used to investigate the cylindrical deep drawing process. The thickness of product and the forming force predicted by current simulation are compared with the experimental data. A finite element method is also used to investigate the maximum forming load and the minimum thickness of products under various process parameter conditions, including the profile radius of die, the clearance between die cavity and punch and the blank holding force. Furthermore, the material anisotropy and process parameters effect on the earing are also investigated.
