Air Bending Sheet Metal

If you bend to a sharp inside corner with sheet metal you ll be adding a ton of internal stresses.

Air bending sheet metal.

When sheet metal is bent it stretches in length. Since the stroke depth is adjustable. 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. Air bending and bottom bending are two of the most common ways to create a bend during sheet metal fabrication.

In this process the workpiece comes in contact with the outside edges of the die as well as the punch tip. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer. The formed bend radius is dependent upon the dies used the material properties and the material thickness.

Air bending is the most common type of 3 types of bending used in sheet metal shops today. Refer to the chart for values for folder as well as various press brake tooling combinations. Punch tip radius air bending when we air bend sheet metal the size of the die v opening determines the inside radius of the bend. The punch tip radius usually has little influence.

The profile of the punch defines the bend radius while the stroke depth defines the bend angle. The metal forms to a natural radius based on the size of the die v opening. Air bending uses a punch tool and an often v shaped bottom die. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

The bend radius refers to the inside radius. Geometry of tooling imposes a minimum bend dimension. This is done through the application of force on a workpiece. 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.

The diagram shows one such mechanism. The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend. Bending is one of the most common sheet metal fabrication operations. The solution is to have a radius on the tool that you ll be using to bend the metal.
