Effect of the Die Conner Radius on the Sheet Metal Hydroforming Process
Main Article Content
Abstract
Drawing is used a lot in the process of the intricate part shaping including traditional drawing, hydromechanical deep drawing, and hydrostatic deep drawing. Each technology has different advantages and applications that depend on the materials, products and production conditions... Hydrostatic deep drawing is used for the products, required shoulder radius little, that is difficult or impossible to fabricate by other methods. The objective of the present study is to determine the influence of corner die shoulder radius in sheet hydrostatic forming process. The shoulder radius plays a vital role in manufacturing the product in deep drawing process to formability and holder force. The present work deals with ZAM steel blank of 0,8 mm in thickness, and 2mm, 3mm, 4 mm, 5 mm and 6 mm for corner radii of the die.
