Edge Bending Sheet Metal

Economy sheet metal benders make bends up to 90 in metal sheets.

Edge bending sheet metal.

These sections are located at the edges. The formed bend radius is dependent upon the dies used the material properties and the material thickness. 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.

The slack between the wipe die and the punch plays an important role in getting a good result. A cutout or the edge of your flange to your bend. Similar to tucking the corners of a bedsheet these benders twist and wrap the metal into triangle shaped folds to form corners.

If you have any questions or want to discuss your design contact us. It is important to make sure that the sheet is properly pushed onto the wipe die.

Choose a bend radius that matches your minimum bend. 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. How to bend sheet metal without a brake. 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.

This is putting a simple hem on a curved piece of zinc with a 7ft radius. Wipe bending or edge bending is another way to bend sheet metal edges. When sheet metal is bent it stretches in length. This page also includes a link to a on line sheet metal bend allowance calculator.

To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. As a result the wipe die also determines the bend s inner radius. We are here to help. 6 t 2 edge distance of v groove 1 8 t 2 t see the picture.

The bend radius refers to the inside radius. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools.
