Sheet Metal Roll Bending And Roll Forming Operations

Sheet metal operations have a very wide range of product types because of the various types of processes. Around the sheet metal bending and sheet metal cutting operations, sheet metal roll bending and roll forming operations are widely used for the production of different kinds of sheet metal products in the industry.

What Is Roll Bending?

Roll bending operations are mainly used for the production of large tanks and large containers that are produced by large sheet metal workpieces. With the help of the set of rolls, the large sheet metal workpieces are drawn through these rolls. At the end section of these rolls, the sheet metal workpiece comes out as a curvature structure. 

With the different arrangements of rolls, the radius of curvature of the sheet metal can change. Different kinds of stock thicknesses also can be rolled with the roll bending operations. 

The inverse of the roll bending processes is also used as ‘roll straightening’ to non-uniform and non-straight sheet metal workpieces. With the series of rolls, non-uniform and non-straight sheet metal stocks can be made straight with the help of rolls. 

Roll Forming Operations

Roll forming operations are very good serial production applications of certain sheet metal parts. In roll forming, rolls have specific shapes and if the sheet metal stock passes through these rolls, they will get the shape of the rolls with very long shapes. 

Several rolls are used to give the required shape to the sheet metal contours. First, it starts with the thinning of the sheet metal stock. With the rolls of the middle side, a partial form is given. And at the end of the rolls, an infinite length of the required contour from the sheet metal workpiece is obtained. That infinite part can be cut according to the required lengths of the product. 

In roll forming processes of sheet metal workpieces, metal channels, gutters, metallic pipes, and tubings with seams are produced in a serial production manner.

These are the general principles of roll bending and the roll forming processes in sheet metal production techniques.
