Improvement in forming process using Magnetorheological Fluid Assisted Cushion in Hydraulic Press

Abstract

The role of cushion pressure in hydraulic press plays a vital role in forming the component. In the present work, an attempt was made to analyse the influence of Magnetorheological cushion in addition to the existing cushion system, in forming small cup shaped component. The innovative Magnetorheological assisted hydraulic press of 1 ton capacity is designed and fabricated. The formability of Aluminium and Galvanised Iron sheet of different thickness was analyzed. The Magnetorheological cushion improves the formability of components with the reduced number of wrinkles in it. The forming process with the Magnetorheological fluid assisted cushion hydraulic press was more efficient than ordinary hydraulic presses.
