Bending can be defined simply as a forming operation in which the metal is deformed along a straight axis.

Coining sheet metal bending.

Bending is one of the most common sheet metal fabrication operations. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. This is mainly for the purpose of reducing the ir of the workpiece so as to reduce the stamping into ir position of the workpiece by the punch tip. The outside bend radius is in tension or being stretched.

In coining the sheet metal is more than just bent it is actually thinned by the impact of the punch and die as it is compressed between them along the bending surfaces fig. Coining sheet metal coining fabrication is a basic type of bending in which the workpiece is stamped between the punch and die. Both the punch tip and the punch actually penetrate into the metal past the neutral axis under a high amount of pressure. Most part defects such as splits and wrinkles occur in forming operations.

Air bending bottom bending and coining. Both compression and tension occur when bending sheet metal. Successful sheet metal forming relies heavily on the metal s mechanical properties. All forming operations deform sheet material by exposing it to tension compression or both.

The metal being formed must have the ability to stretch and compress within given limits. The force must exceed the material s yield strength to achieve a plastic deformation. Air bending is the most common type of bending process used in sheet metal shops today. Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal.

Coining is a form of precision stamping in which a workpiece is subjected to a sufficiently high stress to induce plastic flow on the surface of the material. There are three types of bends used to form metal that any sheet metal engineer or press brake operator must be familiar with. This is done through the application of force on a workpiece. The inside radius of the bent metal is in compression or being squeezed together.

The theory behind coining is that with enough tonnage your sheet metal will bend to the precise angle of your tooling so your tooling should be an equal match to.
