Modeling and analysis of a compound tool for piercing two concentric washers with a singular press action

Abstract

Compound tools are frequently employed in the production of washer components, enabling concurrent blanking and piercing operations. This article explores the creation and examination of a compound tool capable of generating two concentric washers simultaneously. It will eliminate the requirement to build two tools and their associated operation conditions. Unigraphics NX was employed to model and perform finite element analysis on the components of the Compound tool, with the goal of evaluating deformations and stresses. The results produced from theoretical calculations and analytical values are comparable, ensuring that the tool used to manufacture concentric washers operates in a safe manner.
