Bending Sheet Copper

This is done through the application of force on a workpiece.

Bending sheet copper.

Material bend radii and minimum bend size charts please note. Since metal is being pushed pulled and stretched when you bend it calculating bend allowance will give you more reliable numbers to work from when you re laying out a flat sheet. 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. The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.

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. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Mark a bend line and place the sheet metal on the edge of your bench.

If you want a sharp 90 bend tap along the crease with a mallet. Finally bend the sheet up by hand to the angle desired. Clamp the wood on top of the metal to the workbench. There are a few factors that come in to play for this for example the thickness of the material the size of the internal radius etc etc etc.

The force must exceed the material s yield strength to achieve a plastic deformation. 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.
