Roll forming process is the most widely used methodology to form high strength steel for framing in buildings. The roll forming machines fabricate the required configurations out of long strips of coiled steel. Apart from roll forming, these machines also perform a number of other functions such as material cutting and roll punching.
The basic roll forming machine has a line that can be segregated into four major parts. The first part or the entry section is the place where the material is loaded. It is usually put in sheet form or fed from a continuous coil. The next section comprising of station rollers, is the segment where the actual roll forming takes place. It is here that the stations are located and the metal shapes as it makes its way through the process. Station rollers not only shape the metal, but are the very driving force of the machine.
The third section of a basic roll forming machine is the cut off press, where the metal is cut to a pre-determined length. Due to the speed at which the machine operates and the fact that it is a continuously working machine, flying die cut-off techniques are not uncommon. The final section is the exit station, where the finished part exits the machine onto a roller conveyor or assembly line, and is moved.
Roll forming machines are energy efficient as they do not consume energy to heat the material—the metal can be shaped at room temperature. It is also an adjustable process and may be used for projects of varying time duration. The fabrication of precise and uniform parts becomes possible through roll forming.
