Reduction of wrinkling defect in deep drawing process

Abstract

The aim of this experiment is to produce defectless component in deep drawing process and also to increase the quality of finished product. This process is to convert sheet metal into cup and cylindrical component. As the depth of the component is more as compared to diameter, this process is named as deep drawing. During this process, the sheet metal was cut into circular shape and kept on the die. If the die moves against the punch, sheet metal gets compressed and forms a required shape. Hydraulic press was used in this experiment to operate the punch and die set-up. Due to improper clearance and punch force, defect was occurred in drawing components. Most common defects occurred during this process are wrinkle and tear. In this experiment both steel and copper were taken as a base material and deep drawing process was finished with different parameters and defect was analysed.
