Experimental Study on the Effectiveness of Guiding System under Eccentrically Loaded Condition of C-Frame Press

Abstract

This paper presents an investigation on the elastic deflection of C frame press under eccentric load.Various types of guiding system were examined for their effectiveness to increase the process accuracy. Specialtool was designed to measure the deflection of C-frame press in various directions. The experiments were carriedout with various amount of eccentric loading on various types of guiding system as well as without guidingsystem. The result shows less deflection of the press when using die-guiding system as expected. The combinationof large diameter guide pillar and heel block guide provides the maximum improvement of 61.09% in angulardeflection and 49.13% in rotation for eccentric press and 58.3% in angular deflection and 54.02% in rotation forhydraulic press.
