DIE-PRESS CALCULATOR

Introduction - DIE-PRESS calculates the radial and tangential stresses in the inserts and casing in a press-fit die assembly. It determines the optimum interference between the inserts and casing to allow the required pressure for that application. For a 2 or 3 ring die assembly, it determines their dimensions that would allow the dies to take the maximum internal pressure.This Calculator has been developed for tool designers and engineers in the metal forming field including cold forging, hot forging, extrusion and press fitting applications.

Various Applications of this calculator- Cold Forging Tooling, Hot forging tooling, Extrusion Tooling, Press fitting of components. Any application where the tool has to withstand high internal pressure.

Benefits of this calculator Helps to Improve tool life. Allows die assembly to work under higher die pressure. Determines the inserts and casing dimension that optimizes tool material usage. Determine the best press fit amount quickly. Visual presentation of stresses helps in understanding the effect of interference fit in tools.

Types of calculations that it can perform - The program uses the simple theory of thick cylinders to :

• Determine radial and tangential stresses in one ring, two ring and three ring die assemblies with press fit and internal forging pressure
• Determines the optimum intereference to withstand internal pressure in a two ring and a three ring die assembly
• Determine the optimum dimensions of insert outside diameter in Two ring assembly for given insert bore and outside diameter of casing
• Determine the optimum dimensions of insert outside diameter and mid insert diameters in a Three ring assembly for given insert bore and casing outside diameter
• Creates excel reports for all studies
