Explosives can deliver a huge amount of power.
Explosive forming sheet metal.
Explosive forming is a metalworking technique in which an explosive charge is used instead of a punch or press.
It can be used on materials for which a press setup would be prohibitively large or require an unreasonably high pressure and is generally much cheaper than building a large enough and sufficiently high pressure press.
Sometimes called explosive hydroforming a workpiece and explosive is placed in a tank of water.
In normal explosive forming operations the major characteristics of the work metal that determine formability are ductility and toughness.
Detonating a charge above the plate rapidly forces the metal into the desired shape.
Explosive forming is the forming of sheet metal using explosive materials using large amounts of energy over a very short time.
Detonation of the explosive forces the workpiece to assume the shape of the tool.
Explosive forming is an ideal process for producing low volumes of very large metal part with low tooling costs.
Explosive forming a method of forming metals mainly sheet metals in which pressure is created by the force of the blast of a high explosive powder or gaseous mixture through a transmitting medium.
High energy rate forming is the forming of sheet metal by a high energy surge delivered over a very short time.
Formability has been defined as the ability of a sheet metal to be deformed by a specific sheet metal forming process from its original shape to a defined shape without failure.
The die cavity is vacuumed and the assembly is placed in water.
Since the forming of the metal occurs so quickly desirable materials for herf will be ductile at high deformation speeds.
The underwater shock wave travels downstream and then it hits the metal plate to be formed.
An explosive releases its energy instantly so that an extremely high pressure with short duration occurs at the instance of explosion.
An explosive forming is one of the techniques to form a metal plate using high shock pressure from the explosion.
