Bending Cross Sectional Area In Sheet Metal

Sort of like this the width is x d d.

Bending cross sectional area in sheet metal.

As a result the wipe die also determines the bend s inner radius. Percent elongation at frac ture decreases with increasing gage length because of localized necking in the specimen. F stretch forming force lbs ys material yield strength psi uts ultimate tensile strength of the material psi a cross sectional area of the workpiece in2 forces needed to bend sheet metal. Total elongation and reduction of area both increase with increasing cross sectional area of the specimen.

2d x 20 therefore. F ys uts 2 a. Stress distribution through the thickness of the part. A piece of sheet metal w 20 inches wide is bent to form the gutter shown in the illustration.

Let d the debth of the gutter let x the width of the gutter. Where is the area moment of inertia of the cross section is the cross sectional area is the shear modulus is a shear correction factor and is an applied transverse load. Wipe bending or edge bending is another way to bend sheet metal edges. If the cross sectional area is 48 square inches find the depth of the gutter.

The slack between the wipe die and the punch plays an important role in getting a good result. To define the bend region and reduce the force required to bend a part out of sheet metal down to something you can handle without a brake press slots can be cut at the bending line to selectively.
