Edge bending sheet metal.

The bend radius refers to the inside radius. Wipe bending or edge bending is another way to bend sheet metal edges. How to bend sheet metal without a brake. Economy sheet metal benders make bends up to 90 in metal sheets.

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. When sheet metal is bent it stretches in length. This is putting a simple hem on a curved piece of zinc with a 7ft radius. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.

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

Similar to tucking the corners of a bedsheet these benders twist and wrap the metal into triangle shaped folds to form corners. The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. As a result the wipe die also determines the bend s inner radius.

Fold corners in flat metal sheets to create your own bin boxes drip pans and other three dimensional objects. Choose a bend radius that matches your minimum bend. This page also includes a link to a on line sheet metal bend allowance calculator. These sections are located at the edges.

6 t 2 edge distance of v groove 1 8 t 2 t see the picture. Determine your minimum bend by measuring the distance from your closest feature i e. It is important to make sure that the sheet is properly pushed onto the wipe die. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.

To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. A cutout or the edge of your flange to your bend.
