Detailed Content:

Unit I

Design Of Press Tools ( Cutting Dies)

Fourteen steps to design a die.

1. Design of – blanking tool push through type ,blanking tool return type, piercing tool, Progressive tool, compound tool. Design of Bending dies. – Calculation of -developed length, bending force, spring back. Design of V bending dies, edge bending die, channel bending die.
2. Design of Drawing dies:- Drawing die Design consideration – Calculation of blank diameter, number of draws – Pressure – Clearance – Allowance -Radius of draw dies – Punch radius – Drawing speed and single and double action draw dies – Simple Design problems.
3. Drafting Technique ( Not for examination but should be learnt to draw tool drawings – 4 Hour) Die layout, details in plan views, details in cross sectional views, clearance, cross hatching, dimensioning, detail balloons, title block, stock list, change block and equipment block. 45
