Sheet Metal Forming Terms

A constant bending process in which sheet metal coil bar or strips of metal pass through rolls that form the metal.

Sheet metal forming terms.

The process of cutting shearing rolling bending and punching sheet metal to fabricate parts and pieces. The plastic deformation of a piece of sheet metal by tensile loads into a three dimensional shape often without significant changes in sheet thickness or surface characteristics. The process of forming a convex shape in a punch or hydraulic press with the die. A term typically applied to a metal forming process.

The process of connecting two or more pieces of workpiece face to face with rivets if the head is riveted the workpiece must be sunk first. The upper member or members are attached to the slide or slides of the press with the lower member clamped or bolted to the bed or bolster shaped so that the material placed between them is cut or formed when the press makes a stroke. The coils are formed. Bend allowance ba refers to the curved section of metal within the bend the portion of metal that is curved in bending.

Countless everyday objects are fabricated from sheet metal. Sheet metal terminology part 1 roll forming is a constant bending process in which sheet metal coil bar or strips of metal pass through rolls that form the metal. Sheet metal processing terminology 21 30. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes.

Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm are considered plate steel or structural steel. The straining of material usually flat sheetor stripmetal by moving it around a straight axis lying in the neutral plane. Metal flow takes place within the plastic range of the metal so that the bent part retains. Thicknesses can vary significantly.

The bend allowance may be considered as being the length of the curved portion of the neutral line. A tool used on a press for any operation or series of operations such as forming drawing piercing and cutting. An acronym for the sheet metal air conditioning contractors national association. Of a formed feature by angular displacement of a sheet metal workpiece.

Sheet metal is metal formed by an industrial process into thin flat pieces. This arc is called the bend radius.
