Definition Sheet Metal Bending

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

Definition sheet metal bending.

Sheet metal is a processing technology and has not yet had a relatively complete definition. It can crack instead of stretch depending upon several variables including the tooling applied and the direction of the micrograin of the material. This is done through the application of force on a workpiece. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered.

A sharp 90 bend means that the material must go all the way to the corner while the radius bend cheats the corner. Sheet metal stretches when it bends. Metal bending is a process by which metal can be deformed when applying force to the subject which causes it to bend at an angle and form the anticipated shape which often results in it being in a v or a u shape. According to a definition in a professional journal it can be defined as.

Unless dedicated tooling is used the inside radius is likely to vary from batch to batch or from shop to shop. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same. Thicknesses can vary significantly. Sheet metal is metal formed by an industrial process into thin flat pieces.

90 bend the metal would likely crack. This black area is our bend allowance. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry.

The diagram shows one such mechanism. 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. A press brake is a tool used in order to bend sheet metal and uses a punch and die to do this. The pre bent material would have this black area which is formed into the bend.

The process of cutting shearing rolling bending and punching sheet metal to fabricate parts and pieces. Sheet metal is a comprehensive cold working process for metal sheets usually below 6mm including shearing punching cutting folding riveting splicing forming such as car body etc. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Bending is one of the most common sheet metal fabrication operations.

Sheet metal bending bending of sheet metal is a common and vital process in manufacturing industry. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. Geometry of tooling imposes a minimum bend dimension. Refer to the chart for values for folder as well as various press brake tooling combinations.
