Metal stamping shrapnel rebound value how to calculate?

There are a lot of just into the metal stamping shrapnel design engineers in the design of the product forming process of the circular arc R, punch value according to the original value of either do not calculate the springback value of R, or directly to narrow, for example, metal stamping shrapnel value of R = 1, hard materials, take the original value of 0. Eight times, punch R = 0. 8; Soft material value is 0. 9, punch R = 0. 9. Metal stamping promptly tell you today the springback value calculation method. This is only a favor simpler product value, if by this way to test a R value within the larger metal stamping shrapnel, this way, for the most value is inaccurate and that requires an accurate calculation, introduced a general springback formula of shrapnel, now generally apply stamping shrapnel rebound value can be calculated: punch radius R = 1 / [ ( 1 / metal stamping shrapnel radius) + ( 3. 4 x material yield point/materials elastic modulus) ] General material yield strength through the material to material proved to be able to be reflected, can to make it easier to establish a common database query; We usually can be used to improve bending parts by adopting appropriate local structure or material to reduce the springback of metal stamping shrapnel, for some a hard material can undertake annealing treatment. Or the compensation method is adopted, the correction action part of the punch or die shape or size, let stamping rebound worth to compensation, the methods which are frequently used in actual production process.
