Sheet Metal Punching Rules

Sheet Metal Punching Rules

For most common materials we use a simple rule of thumb that the diameter of the hole being punched should be no smaller that the gauge of sheet metal being punched. As the tensile strength of the material increases we would recommend that the punch diameter increases from the thickness of the gauge to 1.5 times the thickness of the sheet metal gauge being punched. Round Hole Perforated Metal Sheets McNICHOLS® (855 Round Hole Perforated Metal, the most popular type of McNICHOLS® Perforated Metal, is available in staggered and straight centers and various diameters, gauges and sheet size options.

Designing Guideline for Sheet Metal Fabrication Apr 15, 2021 · One of the parts is punched, and the other part is punched and cuffed to make it a non-detachable connector. Advantages:the flange is matched with the straight hole, and it has the positioning function itself. The riveting strength is high, and the riveting efficiency through the mold is also high. The specific way is as shown in Figure 1-55: Round - Perforated - Stainless Steel - 18340116
