Web14 jun. 2024 · The first example estimates the fatigue life of a DIN EN 16983 Series B Group 2, DSC 50 × 25.4 × 2 disc spring with a preload of 15% of its initial height with a final position at 75% of its initial height. Using the specification chart in Figure 2, Stress II (σ II) at 15% is 128 N/mm 2 and Stress III (σ III) is 264 N/mm 2. Web21 feb. 2024 · However, if the spring back of the workpiece is minimal when bending soft steel plate less than 2mm, a 90° punch can also be utilized. For materials with a significant amount of spring back (such as SUS, Al or medium plate), the 88° punch, then the 84° punch, and finally the 82° punch can be selected based on the material’s level of spring …
