Bent Sheet Metal Strength

This can be best explained with an example.

Bent sheet metal strength.

The press force increases proportionally with the bending length and is 1 050 80 t at a maximum bending length of 16 m. It is one of the indexes of metal strength. The strength of the table is the force required to bend sheet metal up to 1 m in length. Bending strength it is the maximum stress that the cross section is subjected to when the load is applied between the two points of the specimen.

Rolling sheet metal edges with wire strengthens the panel in two ways that ordinary sheet metal bending doesn t. However ineffective edge bends can also give rise to unwanted complexities. This is done through the application of force on a workpiece. One is that by metal being folded over itself it has doubled in thickness.

In order to bend an s235 sheet of metal with a thickness of 10 mm the press force needed on a die with an 80 mm opening will be 131 35 t. The force must exceed the material s yield strength to achieve a plastic deformation. Edge bending is utilized in almost every sheet metal product design to give strength at the edges as well keep the design safe to be used by the end customers. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
