Folding Sheet Metal Edge To Eliminate Sharpness

Place the fracture line over the edge of a table and bend the overhang slightly downwards.

Folding sheet metal edge to eliminate sharpness.

With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. Figure 3 a sheared sheet metal edge has several attributes that make it sharp. Hems are most often used to remove a sharp untreated edge and make it safe for handling. This technique allows you to dull the edge in one run instead of breaking the edge on the top and.

The slack between the wipe die and the punch plays an important role in getting a good result. This process will round the edge of the metal and create a groove in the point. Many products use sheared sheet metal yet only one standard ul 1439 addresses the issue of sheet metal sharpness directly. Step 1 secure the sheet metal to prevent slipping.

It is important to make sure that the sheet is properly pushed onto the wipe die. 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. Sheet metal s edges particularly with regard to the part after manufacture. Edge bending is used to eliminate sharp edges.

This weakens the aluminium and creates a fracture line. 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. Secure the sheet metal to prevent slipping. Wipe bending or edge bending is another way to bend sheet metal edges.

Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. 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. Multiply 1 8 by 2 1 2 and your answer will be 5 16 inch which you will allow when laying out sheet metal for making the wire edge.

Looking to dull edges on sheet metal for safer fabrication. The edges may appear flat but shearing dies leave burrs. In sheet metal hems are used to create folds in sheet metal in order to stiffen edges and create an edge safe to touch.
