Edge Bending Sheet Metal

It is important to make sure that the sheet is properly pushed onto the wipe die.

Edge bending sheet metal.

How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Wipe bending or edge bending is another way to bend sheet metal edges. Most sheet metal materials will conform to the calculations.

Economy sheet metal benders make bends up to 90 in metal sheets. When sheet metal is bent it stretches in length. 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. Choose a bend radius that matches your minimum bend.

How to bend sheet metal without a brake. 6 t 2 edge distance of v groove 1 8 t 2 t see the picture. A cutout or the edge of your flange to your bend. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance.

This is putting a simple hem on a curved piece of zinc with a 7ft radius. Fold corners in flat metal sheets to create your own bin boxes drip pans and other three dimensional objects. These sections are located at the edges. This page also includes a link to a on line sheet metal bend allowance calculator.

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. 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. The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend. As a result the wipe die also determines the bend s inner radius.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. If you have any questions or want to discuss your design contact us. Similar to tucking the corners of a bedsheet these benders twist and wrap the metal into triangle shaped folds to form corners. We are here to help.

To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. The slack between the wipe die and the punch plays an important role in getting a good result.
