Rolling Edge Of Steel Sheet

With a single tool create both sharp creases and soft curves along the edges of sheet metal.

Rolling edge of steel sheet.

Sheet metal hems are formed using very different methods though produces features with similar uses and functionality. Hence there is a strong motivation to understand the mechanisms of edge crack formation and to develop predictive tools for controlling the phenomenon. Curling is different than a tear drop hem because in a curl the edge finishes inside itself where a hem leaves the initial edge exposed. Pinch rolls stabilize the sheet metal in the grinding zone.

For sheet metal support rolls are needed near the knives or files. Roll sets are available in heat treated tool steel or delrin. The curled edge provides strength to the edge and makes it safe for handling. Rounding off sharp edges with radius cutters good and accurate rounding of steel constructions according to en 1090 iso 12944 iso 8501 or imo pspc is becoming more and more important in the metal working industry.

Use 1 8 markings to set up precise bends. Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion. Unlike benchtop sheet metal tools these shapers are portable so they re often used on site by roofers. Edge cracks need to be removed by a trimming operation and they may cause rupture of the sheet in the rolling mill.

Curling sheet metal is the process of adding a hollow circular roll to the edge of the sheet. Also known as edge rollers these tools slide back and forth along edges to create even bends. Grinding uses driven side rolls see figure 4. 1 4 inch edge bead roll round bead at the edge of sheet metal.

Heat treated tool steel rolls will provide a product details. Curls are most often used to remove a sharp untreated edge and.
