Rolling Edge Of Steel Sheet

Edge cracks need to be removed by a trimming operation and they may cause rupture of the sheet in the rolling mill.

Rolling edge of steel sheet.

Heat treated tool steel rolls will provide a product details. 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. Also known as edge rollers these tools slide back and forth along edges to create even bends. The present work explores the applicability of damage mechanics models to this problem.

Pinch rolls stabilize the sheet metal in the grinding zone. Unlike benchtop sheet metal tools these shapers are portable so they re often used on site by roofers. For sheet metal support rolls are needed near the knives or files. Many metals tend to develop edge cracks during hot and cold rolling.

Curling sheet metal is the process of adding a hollow circular roll to the edge of the sheet. Curls are most often used to remove a sharp untreated edge and. Grinding uses driven side rolls see figure 4. Use 1 8 markings to set up precise bends.

Stationary carbide knives or flat files for smoothing the edges are easy to incorporate into a low speed operation. 1 4 inch edge bead roll round bead at the edge of sheet metal. Hence there is a strong motivation to understand the mechanisms of edge crack formation and to develop predictive tools for controlling the phenomenon. Sheet metal hems are formed using very different methods though produces features with similar uses and functionality.

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.
