Bending Sheet Metal With A Lateral Curl

As a metal rolling company we have been rolling the sheet metal since our conception in 1908.

Bending sheet metal with a lateral curl.

Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the. Basically i want to curl deform a small section of rolled sheet metal away from the main body. Bending is one of the most common sheet metal fabrication operations. Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry.

The force must exceed the material s yield strength to achieve a plastic deformation. Curling is different than a tear drop hem because in a curl the edge finishes inside itself where a hem leaves the initial edge exposed. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm 0 03 inch whichever is larger. Good morning attached are two files showing how i want to bend a piece of sheet metal.

This is done through the application of force on a workpiece. Edge flange design consideration. I hope this reads sensibly. Wilson tool international 1 889 views.

They all are common metal forming operations. Curling means forming an edge of circular cross section along a sheet or at the end of shell or tube. Bends specified as angles may be tolerance at plus or minus one half degree at a location adjacent to the bends. Curling sheet metal is the process of adding a hollow circular roll to the edge of the sheet.

There are multiple manufacturing processes that sheet metal can be formed by bending curling incremental sheet forming laser cutting perforating press brake forming punching roll forming rolling spinning stamping water jet cutting. Place the metal on a hard surface to score it and on long pieces do the bending with the score place along a sharp edge of a bench and if necessary clamp the fixed piece with a long piece of flat wood to prevent buckling the metal while bending it back and forth. The curled edge provides strength to the edge and makes it safe for handling. 47 videos play all bending applications wilson tool international small double decker hinge application with curl tool duration.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
