Bending Corners In Sheet Metal

Bend reliefs in sheet metal.

Bending corners in sheet metal.

Geometry of tooling imposes a minimum bend dimension. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. I have tried various ways in sheetmetal to fill the corner in and currently only a sweep fills in the corner but only as a surface. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

Refer to the chart for values for folder as well as various press brake tooling combinations. Bending is one of the most common sheet metal fabrication operations. The previous notches can be used with a large bend radius if a relief hole or slot is used in the corner see bend reliefs. The part was originally a solid model shown below and am attempting to create filled corners in sheetmetal because the part is made that way.

If you bend to a sharp inside corner with sheet metal you ll be adding a ton of internal stresses. Sheet metal related searches. A short video showing how to bend an outside corner demonstrated on a pro series metal bending machine but applicable to most machines. Don t bend to a sharp internal corner.

This is done through the application of force on a workpiece. See the pic below for solid model corner. The force must exceed the material s yield strength to achieve a plastic deformation. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.

Even on malleable materials you can end up cracking the metal at the bend or weakening it to the point where it ll break with minimal force.
