Edge Bending Sheet Metal

A cutout or the edge of your flange to your bend.

Edge bending sheet metal.

If you have any questions or want to discuss your design contact us. 6 t 2 edge distance of v groove 1 8 t 2 t see the picture. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. The formed bend radius is dependent upon the dies used the material properties and the material thickness.

Wipe bending or edge bending is another way to bend sheet metal edges. 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. 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. Similar to tucking the corners of a bedsheet these benders twist and wrap the metal into triangle shaped folds to form corners.

This page also includes a link to a on line sheet metal bend allowance calculator. When sheet metal is bent it stretches in length. Determine your minimum bend by measuring the distance from your closest feature i e. 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. How to bend sheet metal without a brake. Fold corners in flat metal sheets to create your own bin boxes drip pans and other three dimensional objects. The bend radius refers to the inside radius.

The slack between the wipe die and the punch plays an important role in getting a good result. Choose a bend radius that matches your minimum bend. This is putting a simple hem on a curved piece of zinc with a 7ft radius. 2 the main factors that affect the minimum z bending value are the width of v groove and the distance from the center of the v groove to the edge.

Economy sheet metal benders make bends up to 90 in metal sheets. It is important to make sure that the sheet is properly pushed onto the wipe die. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. As a result the wipe die also determines the bend s inner radius.

To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.
