Edge Bending Sheet Metal

The formed bend radius is dependent upon the dies used the material properties and the material thickness.

Edge bending sheet metal. As a result the wipe die also determines the bend s inner radius. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.

How to bend sheet metal without a brake. The bend radius refers to the inside radius. Edge bending operations are commonly used in industrial sheet metal processing and involve bending a section of the metal that is small relative to the part. Fold corners in flat metal sheets to create your own bin boxes drip pans and other three dimensional objects.

Wipe bending or edge bending is another way to bend sheet metal edges. This page also includes a link to a on line sheet metal bend allowance calculator. The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend. These sections are located at the edges.

Determine your minimum bend by measuring the distance from your closest feature i e. Similar to tucking the corners of a bedsheet these benders twist and wrap the metal into triangle shaped folds to form corners. Economy sheet metal benders make bends up to 90 in metal sheets. This is putting a simple hem on a curved piece of zinc with a 7ft radius.

A cutout or the edge of your flange to your bend. If you have any questions or want to discuss your design contact us. The slack between the wipe die and the punch plays an important role in getting a good result. Edge bending is used to eliminate sharp edges to provide geometric surfaces for purposes such as joining to protect the part to increase stiffness and for cosmetic appearance.

Choose a bend radius that matches your minimum bend. 6 t 2 edge distance of v groove 1 8 t 2 t see the picture. We are here to help. Most sheet metal materials will conform to the calculations.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. When sheet metal is bent it stretches in length.
