Air Bending Of Sheet Metal

For this reason the actual angle of the tooling is relatively unimportant.

Air bending of sheet metal.

Proper bending can be done with annealing the aluminum first although it s not an ideal candidate for formed parts. This is done through the application of force on a workpiece. 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. An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format.

Air bending is the most common type of 3 types of bending used in sheet metal shops today. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Different bend angles can be obtained using the same set of tools. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force.

Refer to the chart for values for folder as well as various press brake tooling combinations. 3a even less contact is made with the metal than with bottom bending. The average hack requires at least one angled metal part and the best tool to make one is still the good ol press brake. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer.

The tooling only touches the material at three points. The diagram shows one such mechanism. Highly formable and one of the best kinds of aluminum to bend. With air bending fig.

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. Air bending also known as free bending is the most common way for bending sheet metal because of its flexibility. The punch tip and the die shoulders fig.

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 punch is then forced past the top of the die into the v opening without coming into contact with the bottom of the v. 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.
