The roller bending machine is a kind of equipment for bending and forming a sheet by using a work roll. It is also named as rolling machine. The rolling machine can form parts of different shapes such as a cylindrical piece and a cone piece. Roller bending machine is a very important metallic processing equipment for industry. The working principle of the roller bending machine is to make the work roll move by the action of external force such as hydraulic pressure and mechanical force, so that the plate is bent or rolled. According to the rotation movement and position change of the work rolls of different shapes, elliptical parts, curved parts, cylindrical parts and the like can be processed.
Roller bending machines vary in types depending on the field of use. From the number of rolls, it is divided into a three-roller and a four-roller rolling machine. Three-roller rolling machine cab be divided into symmetrical three-roller bending machine, horizontal down-regulating three-roller bending machine, arc-down rolling machine, upper-roller and universal three-roller bending machine. Mechanical and hydraulic from the transmission.
