Abstract

One of the manufacturing processes that can be permanent improved is plastic deformation of metallic materials, as incorporating reserves on the manufacture of products with reduced material and energy consumptions. This paper presents finite element analysis for a closed die forging process, showing the stresses, strains and temperature into deformed part and stresses in the working tools. The analysis of obtained results for different flash dimensions of the working tools has enabled optimization of the forging process studied. To be able to validate the numerical results obtained, experimental tests were conducted. The compared data series show a good agreement between the numerical and experimental data.

Highlights

Closed die forging procedure continues to show particular interest because it can produce parts of various shapes and sizes, with high complexity, from different metals and alloys with moderate costs

Summary

Introduction

Closed die forging procedure continues to show particular interest because it can produce parts of various shapes and sizes, with high complexity, from different metals and alloys with moderate costs. For these reasons, research of the forging process in the closed die is current, aiming embodiments, investigation aspects of the interdependence of the various working parameters, the optimum temperature for forging and optimization of the die cavity for a good flow of the metal, increasing the life of the dies. Finite element modelling offers solutions for metal forming processes, to identify fields of variation of displacements and stresses, mainly, and viewing the flow behaviour of the material
