Peen Forming Of Sheet Metals

Dead blow ball peen hammers these hammers have a head loaded with metal shot for added weight and a controlled impact with minimal rebound.

Peen forming of sheet metals.

Also known as body and fender tools these hammers are excellent for forming and repairing dents in sheet metal components. A ball peen hammer. Flexibility peen forming is an incremental forming process which has no defined limits regarding the size or strength of sheet metal components. 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.

It is therefore particularly suitable for complex aerostructures. This article discusses the principle of the process with an emphasis on fundamental mechanisms. The ball forced by compressed air or rotating blade. Shot peen forming is a production process used to create curved metal parts from sheet.

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. Something to cut the metal like sheet metal shears or tin snips. The part to be made by the sheet metal placed on block or it suspended from support and it has blasting together with shot small steel balls. Shot peen forming is a manufacturing process in which local compressive residual stresses form thin sheet metals and structural components in one or more dimensions.

It is an ap plication of shot peening and uses deformations geneated r by impacts of shots thrown to a sheet metal. 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. Something like a sharpie to mark on the sheet metal. It tends to expand the surface of the cold metal thereby inducing compressive stresses.

It is commercially important despite the fact that its mechanisms are not fully understood. A similar sheet metal forming process which is called peen forming has already been developed 8. 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. You may want a smaller hammer for small shapes or a larger hammer for larger shapes.

During the operation blanks are clamped over simple form blocks. It is flexible and independent of tool inaccuracies that result from wear and deflection. I used a 16 oz. The peen forming process not requires any die and forming press.

These features would be difficult or even impossible to manufacture using conventional metal forming techniques.
