What is hydroforming technique?
Hydroforming is a metal forming technology based on the application of pressurized liquid media to generate defined workpiece shapes from tubular materials or sheet metals.
What is explosive hydroforming?
Explosive hydroforming, also known as HERF (High Energy Rate Forming), explosive forming, or exploform, is a striking alternative to the more traditional process of metal hydroforming. Although the charge is relatively small, it is capable of generating enough explosive energy to mold the associated metal into the die.
Which is an example of sheet hydroforming?
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.
What is hydroforming used for?
Hydroforming is used to replace the older process of stamping two part halves and welding them together. It is also used to make parts both more efficiently by eliminating welding as well as creating complex shapes and contours.
Where is hydroforming used?
Today it is mostly used in the automotive sector, where many industrial applications can be found. It is also a method of choice for several tubular members of bicycles. In tube hydroforming pressure is applied to the inside of a tube that is held by dies with the desired cross sections and forms.
Can titanium be hydroformed?
HYDROFORMING WITH TITANIUM Titanium is most often used to make very light, very sturdy metal parts. When component production calls for smooth, complicated shapes — such as in aerospace manufacturing, automotive manufacturing and bicycle manufacturing — hydroformed titanium is especially well suited.
What are the benefits of hydroforming in engineering?
Hydroforming provides the possibility to form hollow complex-shaped components with integrated structures from single initial workpieces, combined with improvements in stiffness and strength behavior due to the reduction of welding seams, and with reduced assembly costs [1].
What are optimization methods used for in hydroforming?
Optimization methods are generally used to determine suitable loading paths for the hydroforming of these components but deeper analyses of this type of process require the development of according models to support a more effective process design.
Which is the first stage of the hydroforming process?
Figure 3 outlines schematically the main stages in the hydroforming process. Initially the preform is cut to the required shape and then located on the diaphragm, which is fixed to the fluid filled chamber. The draw-cap is fixed in position and the punch lowered to form the part against the resistance of the fluid pressure.
Why is hydroforming used in the production of composites?
The main advantage of hydroforming in the production of composite components is that the hydrostatic pressure applies a uniform normal pressure on all surfaces of the laminate, during both the forming and the consolidation phases of the process.
