Explosive Forming Sheet Metal

Explosive forming is a metalworking technique in which an explosive charge is used instead of a punch or press.

Explosive forming sheet metal.

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. An explosive forming is one of the techniques to form a metal plate using high shock pressure from the explosion. High energy rate forming is the forming of sheet metal by a high energy surge delivered over a very short time. In general a metal sheet is placed on a die.

Sometimes called explosive hydroforming a workpiece and explosive is placed in a tank of water. The underwater shock wave travels downstream and then it hits the metal plate to be formed. Detonating a charge above the plate rapidly forces the metal into the desired shape. This presentation will focus on the different uses and methods of explosive forming in the aerospace as well as automotive industry.

In normal explosive forming operations the major characteristics of the work metal that determine formability are ductility and toughness. On the other hand it is unavoidably an individual job. Explosive forming is the forming of sheet metal using explosive materials using large amounts of energy over a very short time.

Since the forming of the metal occurs so quickly desirable materials for herf will be ductile at high deformation speeds.

Explosive forming is an ideal process for producing low volumes of very large metal part with low tooling costs. An explosive releases its energy instantly so that an extremely high pressure with short duration occurs at the instance of explosion. 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. Explosives can deliver a huge amount of power.
