Sheet metal stiffening rib design.

These three simple words can have a tremendous impact on a company s bottom line. The minimum distance between two counterbores is eight times the material thickness. Avoid large sheet metal parts with small bent flanges. In addition the width of a rib should be at least five times the nominal wall.

The stretched metal in those areas will hold tension in the panel and give it structural rigidity. 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 counterbores. Bends can give strength and shape to a part and are formed in a machine using bend brakes. Since sheet metal cannot be bent to a 90 degree position without breaking at sharp corners all bends will have an acceptable bend radius.

Flange hole circular stamp stiffening rib dowel catia v5 duration. The guidelines were designed to aid mainly novice design engineers in early stages of component development. Bends in the same plane should be designed in the same direction.

Sheet metal with structural grooved seams pressing grooves ribs or designs into a piece of sheet metal will greatly increase the strength. For other design load considerations please contact your local contech representative. Generative sheet metal design rolled walls toolbar duration. Existing components were fem analysed and redesigned to investigate the potential weight reduction for using pressing rather than bending.

An hl 93 live load structural check determines if an hs 20 or a tandem axle vehicle controls. Each groove bead or line will compound the strength and can also add a design to the panel. The height of cover tables will vary when a different design method is followed. Officials aashto lrfd bridge design specifications.
