The roller bending machine, also known as a rolling machine, is a pivotal industrial equipment designed for bending and forming sheet metal into various shapes. By utilizing work rolls that are actuated by external forces such as hydraulic or mechanical pressure, the machine can produce cylindrical, conical, elliptical, and curved components through precise rotational movement and positional adjustments of the rolls.

Classified by the number of rolls, roller bending machines are primarily categorized into three-roll and four-roll types. Three-roll machines further include symmetrical three-roll bending machines, horizontal down-regulating three-roll bending machines, arc-down rolling machines, and upper-roller universal three-roll bending machines. These machines can also be distinguished by their transmission methods, which encompass mechanical and hydraulic systems. As a cornerstone of metal processing, the roller bending machine excels in delivering high-precision and versatile forming solutions for diverse industrial applications.
