Description: Introduction Of The Tube Drawing Process When A Hollow Tube Is Drawn Through A Die, Generally A Mandrel Or Plug Is Used To Support The Inside Diameter Of The Tube, This Process Is Called Tube Drawing. The Function Of The Plug Is To Effect Wall Reduction And To Control The Size Of The Hole. However, The Mandrel May Be Omitted If It Is Not Necessary To Make A Reduction In The Wall Thickness, Or If The Dimensions And Surface Of The Inside Are Not Important. The Process To Draw A Pipe Without Any Mandrel Is Known As Tube Sinking. In Drawing Tubes Over A Stationary Mandrel, The Maximum Practical Sectional Area Reduction Does Not Exceed 40 Percent Per Pass The Increased Friction From The Mandrel. If A Carefully Matched Mandrel Floats In The Die Throat Of The Die, It Is Possible To Achieve A Reduction In Area Of 45 Percent, And For The Same Reduction The Drawing Loads Are Lower Than For Drawing With A Fixed Plug. This Style Is Called The Drawing With Floating Plug. To Be Mentioned Is That In This Style, Tool Design And Lubrication Can Be Very Critical. Problems With Friction In Tube Drawing Are Minimized In Drawing With A Long Mandrel. The Mandrel Consists Of Along Hard Rod Or Wire That Extends Over The Entire Length Of The Tube And Is Drawn Through The Die With The Tube. In This Design, The Area Reduction Can Be 50 Percent. However, After Drawing, The Mandrel Must Be Removed From The Tube By Rolling (reeling), Which Increases The
