Bending For Sheet Metal

Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry.

Bending for sheet metal.

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. Thankfully there are a couple of wallet friendly options that can help you get the job done.

This is done through the application of force on a workpiece. Those who work with it regularly are likely to have a sheet metal bending brake in their workshop but this tool can be a bit expensive for the hobbyist. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Bending is one of the most common sheet metal fabrication operations.

If you re bending 0 020 thick material use a 0 020 radius. In some cases bending may produce a small change in sheet thickness. 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. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.

Bending sheet metal can be tricky but with the right tool it s easy. Geometry of tooling imposes a minimum bend dimension. Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the same. Refer to the chart for values for folder as well as various press brake tooling combinations.

Simple sheet metal bender using a hand roller clamps and plywood. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. The inside bend radius should be equal to the thickness of the material that you re forming.
