Peen Forming Of Sheet Metals

Laser peen forming is a purely mechanical forming method achieved through the use of laser energy to form complex shapes or modify curvatures.

Peen forming of sheet metals.

A similar sheet metal forming process which is called peen forming has already been developed 8. It is an ap plication of shot peening and uses deformations geneated r by impacts of shots thrown to a sheet metal. The defor mation mode of peen forming is changed by the depth of plastic deformation zone 9 as shown in. The process parameters can be adapted as required to take account of component features such as varying sheet strengths stringer stiffeners thickened edges pockets and cut outs.

The ball forced by compressed air or rotating blade. The peen forming process not requires any die and forming press. Shot peen forming is a production process used to create curved metal parts from sheet. Also known as body and fender tools these hammers are excellent for forming and repairing dents in sheet metal components.

During the operation blanks are clamped over simple form blocks. It is flexible and independent of tool inaccuracies that result from wear and deflection. Peening is the process of working a metal s surface to improve its material properties usually by mechanical means such as hammer blows by blasting with shot shot peening or blasts of light beams with laser peening peening is normally a cold work process with laser peening being a notable exception. These features would be difficult or even impossible to manufacture using conventional metal forming techniques.

It tends to expand the surface of the cold metal thereby inducing compressive stresses. Dead blow ball peen hammers these hammers have a head loaded with metal shot for added weight and a controlled impact with minimal rebound. It is commercially important despite the fact that its mechanisms are not fully understood. This article discusses the principle of the process with an emphasis on fundamental mechanisms.

And some sand paper to smooth out the edges. You may want a smaller hammer for small shapes or a larger hammer for larger shapes. A ball peen hammer. I used a 16 oz.

Its nonthermal process makes it possible to form sheet metal without material degradation or even improve them by inducing compressive stress over the target surface. It is therefore particularly suitable for complex aerostructures. Something like a sharpie to mark on the sheet metal. Something to cut the metal like sheet metal shears or tin snips.

L aser bending is a non contact forming method for sheet metals in which the sheet metal can be bent shaped and precision aligned with the use of straight or curved laser scan lines to acquire desirable three dimensional 3d features.
