  • Shot Peening Techniques for Springs

    2012-3-26u2002·u2002Peening Torsion Bars Torsion bars are peened in the inline orientation by conveying individual bars on a skew roll conveyor. A single wheel with a variable frequency drive (to alter wheel speed and thereby the velocity) is used to peen the bar as it spins and moves along its length. Valve Springs Smaller springs (typically used in engine valves ...

    Presetting (or 'scragging') and shot peening are two manufacturing operations which are carried out after coiling and heat treatment, but before putting a spring into service. They each confer a favourable residual stress distribution in the wire which increases the allowable operating loads. The stresses in a torsion bar made from an elastic ...
