A roll forming machine is a device that uses working rolls to bend sheet material into shape, capable of forming parts into various shapes such as cylindrical and conical, making it a crucial processing equipment. The working principle of the roll forming machine involves the use of external forces like hydraulic pressure and mechanical force to move the working rolls, thereby bending or rolling the sheet material into the desired shape. Depending on the rotational movement and position changes of the working rolls of different shapes, parts like elliptical, arched, and cylindrical shapes can be produced.
