Analysis of Thickness Distribution in Cup Produced by Rubber Pad Forming

Abstract

In many manufacturing fields such as the aeroplanes and automobiles industries, the control of the thinning variations in produced parts is a major point to investigate since good thickness distribution mean the reliability of these products. In this framework, several experimental and numerical modeling tests have been developed for the purpose of studying phenomenon of thinning during rubber pad forming process. The low carbon steel (AISI 1080) has been used as the blank material. Three forming block shapes had been used (flat, hemispherical and complex), rubber pad with three different hardness (50, 60 and 70 Shore A) also the rubber pad thickness have (40, 60 and 80 mm). The results have showed that improvement in thickness distribution occurred with decrease in rubber hardness and thickness distribution is various from one deformation style to other.
