Bending Sheet Metal Into A Box

Bend the top edges over.

Bending sheet metal into a box.

Typically the upper beam or punch holder will get in the way of very deep boxes. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. Insert the first edge into a bending brake.

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. Once all of the squares are cut out you ll be left with the four flaps. Make sure that it is lined up with the line you measured earlier. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.

Box bending can be rather tricky with sheet metal because of the geometry of a press brake. How to bend sheet metal without a brake. The force must exceed the material s yield strength to achieve a plastic deformation. Bending is one of the most common sheet metal fabrication operations.

This will create a lip. Bend the edge 90. When bending with large returns there are a few tricks outside of just tooling selection. This is done through the application of force on a workpiece.
