Design and Analysis of Die and Punch used for Deep Drawing Operation for Daulat Industries, Gaddi Godam, Nagpur

In this paper, in a deep drawing operation carried in Daulat Industries, Gaddi godam, Nagpur, a sheet metal called blank is placed on a die cavity, held in position using a holding plate or holding ring and pressed against the die cavity using a solid punch. The sheet metal attains the shape of the die cavity with flat bottom. Both die and punch should be provided with corner radius in order to avoid shearing of the sheet. Very limited and small amount of work for design improvement in shape of die, improvement in defects and analysis on suitable die punch shape has been observed and there is still a need for further work. At present the company is not able to produce their product with the mentioned qualities. The company is not equipped with the CAD and FEA techniques because of which they lack the qualities in their product and results in failure. By generating appropriate design in CAD and simulate by using FEA techniques on their product we will be able to improve the qualities (i.e. weight, strength, density, and corrosion resistance) which will ultimately benefit the company and reduce their time and effort.
