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 die cavity is vacuumed and the assembly is placed in water. 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. Explosive forming is a metalworking technique in which an explosive charge is used instead of a punch or press.

An explosive forming is one of the techniques to form a metal plate using high shock pressure from the explosion. Explosive forming ik splō siv fȯr miŋ metallurgy shaping metal parts in dies by using an explosive charge to generate forming pressure. An explosive releases its energy instantly so that an extremely high pressure with short duration occurs at the instance of explosion. 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.

Sometimes called explosive hydroforming a workpiece and explosive is placed in a tank of water. Please like share subscribe for more videos. 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.

On the other hand it is unavoidably an individual job. Explosive forming is an ideal process for producing low volumes of very large metal part with low tooling costs. The underwater shock wave travels downstream and then it hits the metal plate to be formed. High energy rate forming is the forming of sheet metal by a high energy surge delivered 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. 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.

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.
