Bending Sheet Metal With A Lateral Curl
The curled edge provides strength to the edge and makes it safe for handling.
Bending sheet metal with a lateral curl. 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. Good morning attached are two files showing how i want to bend a piece of sheet metal. How are bending flanging coining embossing stretching curling hemming ironing necking and drawing related. 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.
Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the. As a metal rolling company we have been rolling the sheet metal since our conception in 1908. 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. Find out more about these processes in this final installment of stamping expert art hedrick s sheet metal stamping series.
They all are common metal forming operations. The force must exceed the material s yield strength to achieve a plastic deformation. I hope this reads sensibly. This is done through the application of force on a workpiece.
Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry. Curling means forming an edge of circular cross section along a sheet or at the end of shell or tube. Wilson tool international 1 889 views.
Basically i want to curl deform a small section of rolled sheet metal away from the main body. 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. 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.
