What is tube hydroforming?
Tube hydroforming is the expansion of metal tubes into a shape using two die halves, which contain the raw tube. When compared to traditional metal stamped and welded parts, hydroformed parts are lightweight, have a lower cost per unit, and are made with a higher stiffness to weight ratio.
How does the hydroforming process work?
Hydroforming is a specialized type of die forming that uses a high pressure hydraulic fluid to press room temperature working material into a die. High pressure hydraulic pumps then inject fluid at very high pressure inside the aluminium tube which causes it to expand until it matches the mold.
What is a Hydroform press?
Hydroforming is a metal forming process that uses pressurized hydraulic fluid in a flexible diaphragm to shape sheet metal against a single tool. Beckwood’s standard line of Triform sheet hydroforming presses includes both fluid cell and deep draw configurations.
Can titanium be hydroformed?
HYDROFORMING WITH TITANIUM When component production calls for smooth, complicated shapes — such as in aerospace manufacturing, automotive manufacturing and bicycle manufacturing — hydroformed titanium is especially well suited. Hydroforming titanium is a more cost-effective method for forming this costly metal.
What are the advantages of hydroforming?
ADVANTAGES OF HYDROFORMING PROCESS Material thinout is minimized. Multiple conventional draw operations can be replaced by one cycle in a hydroforming press. Hydroforming process is ideal for complex shapes and irregular contours. Materials and blank thickness specifications can be optimized to achieve cost savings.
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 fluid is used in hydroforming?
Tube hydroforming is a metal forming process which uses pressurized fluids such as water to make various perimeter shapes from tubes.
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.
Why is hydroforming explosive?
The Benefits of Explosive Hydroforming The smoothness of the contours of the molded metal is easier to control. It can produce large components, thus eliminating the need for costly welds. The process is less expensive than super-plastic forming. Tolerances are capable of maintaining precision.
What are the Herf process?
Principle / important features of HERF processes: The energy of deformation is delivered at a much higher rate than in conventional practice. Larger energy is applied for a very short interval of time. The velocity of deformation is also very large and hence these are also called High Velocity Forming (HVF) processes.
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.
Which energy is used in Herf?
Explosive forming is a HERF process that forms parts using the explosive force of a chemical reaction. The process uses energy in the form of a high-velocity shock wave to deform workpieces at rates of several hundred meters per second.
What kind of control does a tube hydroforming machine have?
Figure 1Modern hydroforming machines have independent control of axial feeding, internal pressure, and counterpressure. Tube hydroforming has been well-known since the 1950s.
When did tube hydroforming become a mass production method?
Tube hydroforming has been well-known since the 1950s. However, with recent advancements in computer controls and high-pressure hydraulic systems, the process has become a viable method for mass production, especially with the use of internal pressures of up to 6,000 pounds per square inch (PSI).
How are corrugations formed in a hydroforming machine?
The welded pipe is placed inside a set of movable plates and the bellow’s corrugations are formed when the internal hydraulic pressure (water) expands the pipe outwards between the plates. When the pipe expands, it is folded longitudinally to produce a complete convoluted bellow in one operation.
Why do we use thin wall tubular hydroforming?
Our specialization in thin wall tubular hydroforming allows us to produce lightweight, complex parts with seamless aesthetics that would be impossible to cost-effectively reproduce using traditional forming methods. If playback doesn’t begin shortly, try restarting your device.
