What is tubular hydroforming?
Tubular Hydroforming is a cost effective way of shaping pliable metals such as aluminum, brass, and low alloy stainless steel. The process has been used since the 1950’s. The control of these combined variables gives tubular hydroforming the upper hand in metal forming over older, more dated machinery and techniques.
Which is a type of hydroforming process?
Generally there are two classifications used to describe hydroforming, sheet hydroforming and tube hydroforming. Sheet hydroforming uses one die and a sheet of metal; the blank sheet is driven into the die by high pressure water on one side of the sheet forming the desired shape.
What are the two types of hydroforming?
There are two types of hydroforming; sheet hydroforming and tube hydroforming. For sheet hydroforming, a metal blank sheet is placed over the mold.
What are the advantages of hydroforming?
Hydroforming provides several advantages in the manufacture of aerospace parts and components, including greater geometric possibilities, superior surface finishes, and more economical, streamlined operations.
What is the most important parameter in hydroforming?
Next to the feature height, the thickness of the original blank sheet, the feature radius and die height are the most important parameters.
What is electro hydraulic forming process?
Electrohydraulic forming is a type of metal forming in which an electric arc discharge in liquid is used to convert electrical energy to mechanical energy and change the shape of the workpiece. The electric arc discharge rapidly vaporizes the surrounding fluid, creating a shock wave.
Which is the disadvantage of hydro forming process?
The disadvantages of sheet hydroforming include relatively slower cycle time, expensive equipment, and so on. In general, any sheet metal material capable of being cold formed, such as carbon steel, aluminum, stainless steel, copper, and brass, is a candidate for hydroforming.
Which of the following can be manufactured using hydroforming?
In the automotive industry, hydroforming is primarily used to manufacture components for exhaust systems and various chassis and body parts. These include, for example, motor, cross and side beams, roof frames, as well as A-, B- and C-pillars.
What is electrohydraulic forming used for?
Unsourced material may be challenged and removed. Electrohydraulic forming is a type of metal forming in which an electric arc discharge in liquid is used to convert electrical energy to mechanical energy and change the shape of the workpiece.
What is explosive forming?
An explosive forming is one of the techniques to form a metal plate using high shock pressure from the explosion. An explosive releases its energy instantly so that an extremely high pressure with short duration occurs at the instance of explosion. Because of this effect, the metal plate may stop its deformation.
What is Herf process?
To enhance the material performance, a high energy rate forming technique is of great importance to industry, which relies on a long and trouble free forming process. High energy rate forming (HERF) is the shaping of materials by rapidly conveying energy to them for short time durations.
How are tubes formed in a hydroforming process?
Tube hydroforming is a metal forming process which uses pressurized fluids such as water to make various perimeter shapes from tubes. Compared with stampings and castings, hydroformed tubular sections provide further mass savings for structural components.
How is hydroforming used in metal fabricating?
Hydroforming is a cost-effective metal fabricating process that can form complex geometries in tubular based parts and extended deep draws in sheet metal-based parts. Hydroformed parts allow for parts consolidation, the reduced number of sub components reduces assembly costs and increases strength and stiffness of the final assembly.
How is pressure used in the hydroforming process?
The hydroforming process utilizes fluid pressure behind a rubber diaphragm to force a sheet of material into the shape of an adjoining mold.
What are the advantages of tubular hydroforming construction?
Hydroforming tubular components offers several advantages, including: Part consolidation. Weight reduction through more efficient section design and tailoring of the wall thickness. Improved structural strength and stiffness. Lower tooling cost as a result of fewer parts. Fewer secondary operations.
