DESIGN AND ANALYSIS OF PUNCHING DIE

Abstract

The sheet metal working processes is predominantly used in various aspects not only for industrial purposes and also utilized for commercial purposes as well. For that many people are engaged in developing the trends by their innovative ideas. Especially in die design, they made different die set for different functionality such as compound die, progressive die, steel-rule die, modular die, sectional die, transfer die, etc. These die are functioned with their own perspective criteria. Due to this, peoples are in Micro small medium scale industries suffered from investing more in single die set. They are unable to overcome the profit with better margins and some are in dead weight which is very difficult to handle by a single person. The main aim of this paper is to design a die with interchangeable die and punches and reduce the weight of the material by means of changing the materials of die sets. This paper mainly focuses on different operations done in single die set with various stations just like a progressive die. But the difference is mode of operation-Progressive die can perform a sequence of operation at a single stroke of press, here this die can perform an individual operation in each station on the die set at a single stroke of press. This should constantly eliminating the loss in production time and reduces the man power from loading and unloading the sheets. The parts of the die sets, punch and die are designed in the solid works and assembled with the mounting hardware. The Finite element analysis of each part of the die sets are done with the simulationxpress tool.
