A four-roller plate rolling machine is a mechanical or hydraulic-driven device used for forming curved surfaces from flat metal sheets. It achieves this through the synchronized operation of its four rollers, making it an essential tool in modern metal forming processes.
The four-roller plate rolling machine is superior to the three-roller plate rolling machine in terms of ease of operation, pre-bending effect, forming accuracy, production efficiency, scope of application, degree of automation and safety.
Structure and Components
- Upper Roll: The primary roll that applies downward pressure to bend the metal plate.
- Lower Roll: Functions as a supporting roll and can be adjusted to modify the plate's position and force distribution.
- Side Rolls (Two): Located on either side of the upper roll, these assist in pre-bending and guiding the plate during rolling.
- Drive System: Includes motors, hydraulic systems, or mechanical transmission mechanisms to power roller movements.
- Control System: Modern machines often feature CNC (Computer Numerical Control) or servo systems for automated operation and enhanced precision.
A four-roller plate rolling machine, also known as a four-roll bending machine, is an advanced metalworking device designed to bend metal sheets into cylindrical, conical, or other curved shapes. It features a four-roller configuration consisting of an upper roll, a lower roll, and two side rolls. By coordinating the movements of these four rollers, the machine provides precise pre-bending and rolling of metal plates.
- Pre-Bending: Side rollers are positioned to pre-bend the edges of the metal plate, minimizing flat ends and improving product quality......
- Rolling: The upper and lower rollers exert pressure while the side rollers provide guidance, forming the plate into a cylindrical or conical shape......
- Fine Tuning: The roller positions are adjusted as needed to ensure precise shaping of the final product.
