Abstract

Deep drawing is a very important metal forming process. Thin steel sheet is important material for manufacture of numerous products with deep drawing and stamping. Cold working provides also the possibility of making parts of various shapes, from the simplest to those with a high degree of complexity whose execution through other methods is uneconomical, difficult and sometimes even impossible. In this paper it is analyzed both experimentally and with the help of the finite element, the behavior of the blank during the cylindrical cup deep drawing process, using the ANSYS software program and the finite element method. A comparison is realized between the experimental and the analytical results, elaborating a representative set of problems that analyze the variation of the die punch clearance, movement of the punch and with or without lubrication. The results of the research are useful in developing a sensible design of experiments.

Highlights

Cold deformation is one of the modern methods, widely used in machine building and, in particular, in the construction of motor vehicles, aircrafts, machinery and electrical appliances, fine mechanics, agricultural machinery and tractors, etc.The process of metal processing by plastic deformation, respectively the deep drawing process, is an extremely extensive field of research [1]
The experimental and finite element values obtained in the two lubrication cases are obtained by making the arithmetic average, in the case of the punch displacement value and the time required to perform the deep drawing operation
To study the behavior of the S235JR material using the finite element method, it was envisaged to create a three-dimensional model that fully complies with the active element geometry made in the CATIA drawing program by saving the file with the * .igs extension, in order to be able import

Summary

Introduction

Cold deformation is one of the modern methods, widely used in machine building and, in particular, in the construction of motor vehicles, aircrafts, machinery and electrical appliances, fine mechanics, agricultural machinery and tractors, etc.The process of metal processing by plastic deformation, respectively the deep drawing process, is an extremely extensive field of research [1]. This approach, according to the latest studies, seems to be important in order to ensure the optimum price-quality ratio [3]
