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.

Explosive forming sheet metal.

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. Detonation of the explosive forces the workpiece to assume the shape of the tool. Http vid io xvgs explosive forming process high energy rate forming process engineering stu.

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. An explosive forming is one of the techniques to form a metal plate using high shock pressure from the explosion. On the other hand it is unavoidably an individual job. Sometimes called explosive hydroforming a workpiece and explosive is placed in a tank of water.

Explosive forming is a metalworking technique in which an explosive charge is used instead of a punch or press. High energy rate forming is the forming of sheet metal by a high energy surge delivered over a very short time. Explosives can deliver a huge amount of power. In general a metal sheet is placed on a die.

Explosive forming involves placing a metal plate submerged in water above a die or mold. This presentation will focus on the different uses and methods of explosive forming in the aerospace as well as automotive industry. Detonating a charge above the plate rapidly forces the metal into the desired shape. Since the forming of the metal occurs so quickly desirable materials for herf will be ductile at high deformation speeds.

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. Explosive forming ik splō siv fȯr miŋ metallurgy shaping metal parts in dies by using an explosive charge to generate forming pressure. Explosive forming is the forming of sheet metal using explosive materials using large amounts of energy over a very short time.

In normal explosive forming operations the major characteristics of the work metal that determine formability are ductility and toughness.
