OUTLINE: What is Hydroforming How and where is Hydroforming utilized Materials utilized as a part of Hydroforming procedures Design Considerations Advantages/Disadvantages Economics of Hydroforming Websites and Links Conclusion

Slide 3

Hydroforming utilizes the drive of water or pressure driven liquids to shape a solitary part. There are two sorts of hydroforming: 1. Tube hydroforming 2. Sheet hydroforming

Slide 4

TUBE HYDROFORMING Used when a mind boggling shape is required An area of chilly moved steel tubing is put in a shut bite the dust set A pressurized liquid is brought into the closures of the tube The tube is reshaped to the limit of the hole

Slide 5

SHEET HYDROFORMING 2 METHODS: Sheet steel is constrained into a female depression by water under weight from a pump or by press activity Sheet steel is disfigured by a male punch, which acts against the liquid under weight. Note: Sheet hydroforming gives a work-solidifying impact as the steel is constrained against the spaces through liquid weight.

MATERIALS Steel (mellow and harder steels) Stainless Steel Aluminum combinations Research keeps on growing the capacities of the hydroforming procedure

Slide 9

DESIGN CONSIDERATIONS Hydroforming is for the most part characterized as either low-weight or high weight. The outline point is 83MPa Constant weight volumetric development < 5% required to shape the part = Low weight > 5% (however < 25%) = High Pressure

DESIGN CONSIDERATIONS Tool/Dies - Geometry of instruments - Material hardness - Surface conditions - Stiffness and precision Equipment - Press limit - Speed/creation rate - Force/vitality abilities - Rigidity and exactness Product - Geometry, thickness circulation - Dimensional precision/resiliences - Surface complete - Microstructure, mechanical and metallurgical properties, hardness Deformation zone - Deformation mechanics, show utilized for examination - Metal stream, speeds, strain rates, strains (kinematics) - Stresses (variety amid distortion) Work piece/Material Flow worry as a component of strain, strain rate and microstructure Workability as an element of strain, strain rate and microstructure - Surface conditions - Geometry of tubing ( outside measurement, tube divider thickness, roundness, properties of welding line, and so forth.)

ADVANTAGES Hydroforming draws material into the form Part combination Weight lessening through more proficient area plan and fitting of the divider thickness Improved auxiliary quality and solidness Lower tooling cost because of less parts Fewer optional operations (no welding of segments required and gaps might be punched amid hydroforming) Tight dimensional resistances and low spring back Reduced piece

Slide 12

ADVANTAGES (CONT.) Results contrasted with routine steel body structure: half less weight 45% less parts (less devices, less get together) 45% less welding creases Tighter resiliences Volvo Hydroformed Structure idea in Aluminum, (Schuler Hydroforming 1998)

Slide 13

DISADVANTAGES Slow process duration Expensive hardware and absence of broad information base for process and apparatus configuration Requires new welding strategies for gathering.

CONCLUSION Hydroforming is an imaginative framing process Hydroforming is turning out to be more well known (ie.automotive and aviation enterprises) The favorable circumstances exceed the impediments Material determination is expansive and keeps on expanding Information can be discovered all over!
