The sheet metal thickness is 0.08", bend radius is 0.05". Reply reply . The rule of thumb is minimum distance from outside edge of a hole to the inside material face is equal to 2 times the material thickness plus the bend radius. Reply reply Joaquin2071 .
4) After the bending, the hole reaming process only has one or several pixel holes to the bending line and the distance is less than the minimum hole distance.When the appearance of the product is strict, in order to avoid the drawing during bending, the pixel can be performed at this time.Shrinkage treatment, that is, cutting a small .
• Hole to Bend (H2B) ± .015" • Hole to Edge (H2E) ± .010" . cutting and 0.5-6 mm for bending. Fabricators bend sheet metal using rolling machines, press brakes, and other equipment to create standard shapes such as U- or V-bends. . The countersinks should be separated by eight times the distance to prevent cracks and breakage from .
Fig.: Bending specs for 0.040” 5052 Aluminum. Bend Length. The bend length, or width of the flange, is dependent on, wait for it, the material properties: For the 304 Stainless in the previous example, the maximum length is 36” while a thinner, more ductile material like the the 5052 aluminum can easily be bent all the way up to the max part size of 44”.If you use the sheet metal tools in Solidworks (or most other CAD software), some of the cuts and notches are generated kind of automatically when you bend a side, etc. . and the call-outs for thru/countersunk holes. We never specified the bend radius, simply shaved down the milled-end where the bend radius was too large and didn't fit .If a hole is too close to a part edge or bend, the edge might become distorted. To configure this rule, set Simple Hole-Part Edge Distance to Thickness Ratio and Countersink-Part Edge Distance to Thickness Ratio.outside the bend radius, so that the sheet is flat. Once the first two criteria are met, the fastener may be installed as close to the bend as the installation tooling will allow. Min. Dist.
