Sheetmetal bending


Sheet metal bending should be as perpendicular as possible to the direction of the metal fiber. When the sheet metal bend is parallel to the direction of the fiber of the metal material, cracks are likely to occur at the bend of the sheet metal, and the bending strength is low and it is easy to break, as shown in the following figure. Mar 28, 2019 · Most frequently, expensive sheet metal bending tools, called brakes, are used to bend sheet metal, but you can also complete this task without one. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. Sheet metal bending is a forming operation. Where sheets are deformed plastically to change its shape. During bending, material is stressed beyond its yield strength but below the ultimate tensile strength. Bending is one of the most common sheet metal fabrication operations. Also known as press braking, flanging, die bending, folding and edging, this method is used to deform a material to an angular shape. This is done through the application of force on a workpiece. The force must exceed the material’s yield strength to achieve a plastic deformation. Sheet metal bending should be as perpendicular as possible to the direction of the metal fiber. When the sheet metal bend is parallel to the direction of the fiber of the metal material, cracks are likely to occur at the bend of the sheet metal, and the bending strength is low and it is easy to break, as shown in the following figure.
