HYDRO FORMING INTRODUCTION Hydro Forming High Pressure Water

HYDRO FORMING

INTRODUCTION ² Hydro Forming ² High Pressure Water As a Punch ² Widely Used In Automobile Industry

HYDRO FORMED COMPONENTS Fig. Automobile component & Bellows

Fig. Hydro formed handle bar Fig. Hydro formed T-junction

METHODS OF HYDROFORMING There are two types ² Tube Hydro Forming ² Sheet Hydro Forming

TUBE HYDRO FORMING ² To Produce Tubular Components ² High Pressure Process ² Plastic Deformation ² Manufacture Components At One Step

Step 1 Step 2 Fig. Final Product Step 3

BENEFITS OF TUBE HYDRO FORMING ² Increased Strength to Weight Ratio’s ² Reduction In Weight ² Reduction In Production Cost ² Reduction In Number Of Manufacturing Stages ² Improved Stiffness, Torsion And Bending Rigidity ² Less Floor Area

SHEET HYDRO FORMING ² To Produce Components Made Of Sheet ² High Pressure Process ² Two Stage Process ² Types Of Sheet Hydro Forming

SINGLE SHEET HYDRO FORMING

Hydro formed roof rail Hydro formed chair . Hydro formed automobile component

DOUBLE SHEET HYDRO FORMING ² Structurally Closed Components Are Formed By This Process ² High Pressure Process

APPLICATION SPECTRUM ² ² ² Automotive Components Well Suited To Hydro Forming Of Sheets. Outer Skin With Its Extreme Demand Of Surface Quality And Dimensional Accuracy Longer Outer Skin Parts For Passenger cars, Utility Vehicles And Truck Such As Goods

APPLICATIONS OF SHEET HYDO FORMING ² ² Low capital cost Reduction in weight High process capability Reduction in cost of component

FORMING LIMIT DIAGRAM ² Deformation In A Forged Part Is Analyzed From FLD ² If Both Major & Minor Strains Are Positive Deformation Is Known As Stretching

HYDRO FORMING PROCESS CONTROL ² Controller Plays A Virtual Role In Displaying, Monitoring And Controlling

CONCLUSION ² Hydro Forming Is Not Solution For Manufacturing All Automotive Parts. ² This Process Is Economic And Weight of Components Can Be Reduced By Hydro Forming ² Just Like Transistor Revolutionized The Electronic Industry, Hydro Forming Has Taken The Vehicle Manufacturing Industry A Step Up To Evolutionary Ladder.
