Abstract:
The shape accuracy of the products in press bending is rather low because of spring back phenomenon. In this report the application of peen forming as a means for the
improvement of shape accuracy is dealt with. Peen forming accompanying elastic pre-bending enables stable precise V-bending of thin phosphor bronze sheet regardless of the
fluctuation of the sheet thickness. By applying auxiliary peen forming at the final stage of the press U-bending just before taking out the product, the desired fit product
to the punch shape can be obtained.
Descriptors: Shape accuracy; Stable precise bending; Auxiliary means; U-bending
