Bending Corners In Sheet Metal

Refer to the chart for values for folder as well as various press brake tooling combinations.

Bending corners in sheet metal.

See the pic below for solid model corner. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Don t bend to a sharp internal corner. This is done through the application of force on a workpiece.

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. If no relief distance is called out on the print and you are using a large bend radius with this type of notch then to be safe use a minimum distance of the material the bend radius. Bend reliefs in sheet metal. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.

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

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. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. The force must exceed the material s yield strength to achieve a plastic deformation. The diagram shows one such mechanism.

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.
