Abstract

Numerical and experimental investigations on the effects of variable cavity pressure on the formability of GLARE using hydromechanical deep drawing

Highlights

Increasing efficiency by reducing vehicle weight while maintaining high safety is one of the primary aims of numerous industries such as aerospace and automobile in the modern era
Blala et al in his study of process parameters such as blank holder gap, cavity pressure, and blank holder force on the final quality of hemispherical cup made of 1.2mm thickness 2/1 glare laminate achieved by using mechanical hydroforming and got good results in making the significant depth of 26mm with no wrinkling while having a suitable blank holder gap of 1.1mm which was less than the total thickness of
In this investigation, different parameters were set including blank holder force 12 KN and blank holder gap 1.1mm were fixed while cavity pressure was changed from 2 to 10 MPa to obtain the results as given in tables 2A and 2B

Summary

Introduction

Increasing efficiency by reducing vehicle weight while maintaining high safety is one of the primary aims of numerous industries such as aerospace and automobile in the modern era. Experiments were performed at room temperature on a 50-ton hydroforming machine which is shown in figure 2 This machine was managed by a hydraulic feed controller which was linked to computer software that measured various forming process parameters such as blank holder force, cavity pressure, feed rate, and deep drawing distance. Blala et al in his study of process parameters such as blank holder gap, cavity pressure, and blank holder force on the final quality of hemispherical cup made of 1.2mm thickness 2/1 glare laminate achieved by using mechanical hydroforming and got good results in making the significant depth of 26mm with no wrinkling while having a suitable blank holder gap of 1.1mm which was less than the total thickness of [29] in our study 1.1mm fix BHG was used. Fix blank holder gap of 1.1mm as explained above was used, an amplitude tool w.r.t step time was applied in the software
