Folding Sheet Metal Edge To Eliminate Sharpness

Edge bending operations are commonly used in industrial sheet metal processing and involve bending a section of the metal that is small relative to the part.

Folding sheet metal edge to eliminate sharpness. Use a die grinder with the mounted point and simply run the point over the edge of the sheet metal. The edges may appear flat but shearing dies leave burrs. Edge bending is used to eliminate sharp edges. Secure the sheet metal to prevent slipping.

Run the point over the other sides to break those sharp edges. Step 2 use your die grinder with a mounted point we like shape w222 and simply run the point over the edge of the sheet metal. A blanked edge condition can be improved by adjusting the punch and die clearance tolerance shaving the area of the defective blanked edge designing an appropriate contact profile of the tool and die and understanding the mechanical properties of the sheet metal used. Place the fracture line over the edge of a table and bend the overhang slightly downwards.

Figure 3 a sheared sheet metal edge has several attributes that make it sharp. These sections are located at the edges. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. This process will round the edge of the metal and create a groove in the point.

As the groove in the point wears just move down the point to create a new groove and so on. Many products use sheared sheet metal yet only one standard ul 1439 addresses the issue of sheet metal sharpness directly. Run the mounted point over the other sides to break those sharp edges. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.

Step 3 repeat. Step 1 secure the sheet metal to prevent slipping.
