1 CHAPTER 1 INTRODUCTION

1.1 Introduction

The die design, a large division of tool engineering, is a complex, fascinating subject. It is one of the most exciting of all the areas the general field of tool engineering. The word ‘die’ is very general one and it may be well to define its meaning as in this project report. It is used in two distinct ways. When employed in general sense, its mean an entire press tool with all component taken together. When used in a more limited manner, it refer to that components which is machined to receive the blank, as differentiated from the component called the ‘punch’ which is its opposite member. In this project, the new die design of a proper punch and die will be discussed. Starting by designing model of extrusion die and optimize the main parameter are geometry model of punch and the angle of the die has been analyze using finite element analysis FEA software. Then few proposed optimization will be developed and be evaluated to find the best solution for the cavity problem.

1.2 Problem Statement

For this project, the main problems that will be considered are die design and die optimization to reduce cavity. The story of an extrusion die begins with a design idea. Design specification documentation is drawn up outlining the basic definition, appearance and the technical structure of the extrusion die. This idea is then brought to life using special CAD software to create the first 3D model for testing. The 2 software allows the extrusion die to be turned three-dimensionally and for improvements to be made easily. Many specifications that must be considered before design the extrusion die. Die design for a new product is developed on the basis of previous experience and experimentation. It is effective for analysis of material flow, temperature distribution and load estimation if die design is specified. But 3D simulation becomes time consuming when many simulation trials are required for development of die shape and searching for optimal position of orifice. By using the new software today, we not only can design the die extrusion but also can analysis the product in details. The defects from the design can be detected when doing a simulation on the product. By using FEA simulation software Deform V10, the more precise and accurate result will be get.
