Four-roller plate rolling machine is a common metal processing equipment, which is mainly used to roll metal materials (such as steel plates, aluminum plates, etc.) into the required shape and size through the curling action of rollers.
CNC four-roller plate rolling machine is a metal plate bending and correction machine, which is specially used for the forming and bending of metal plates. The pre-bending and curling of various specifications of cylindrical and arc-shaped workpieces can be completed after one loading. With the help of auxiliary devices, the conical cylinder can be rolled. The metal sheet can also be roughly shaped.
Structural composition: The four-roller plate rolling machine is mainly composed of a base, an upper roller, a lower roller and a side roller. Among them, the upper roller and the lower roller are used to provide the rolling force, while the side roller is used to control the position and shape of the metal material.
Working principle of four-roller plate rolling machine
The four-roller plate rolling machine uses the curling action of the upper roller and the lower roller to gradually roll the metal material into the required shape between the two. Simply put, the four-roller plate rolling machine gradually rolls the metal sheet into the required shape through the friction and compression force between the four rollers.
The position and speed of the four rollers can be adjusted to achieve different rolling results. The upper and lower rollers can be adjusted in position and pressure by hydraulic system or mechanical control, and the side rollers can also be moved and adjusted by mechanical or hydraulic system. The support rollers are used to support the metal sheet to prevent deformation or creases.
Five advantages and features of the four-roller plate rolling machine
- The automatic material alignment function enables the plate to be automatically aligned under the push of the rear roller;
- The upper and lower rollers accurately clamp the plate to ensure the shortest straight edge length;
- The plate is always clamped between the upper and lower rollers to ensure consistent positioning;
- The entire cylinder is rolled in one time, including pre-bending at both ends, without turning around;
- The auxiliary equipment includes centralized control of alignment, pre-bending and rolling to achieve fast and safe pre-bending without damage to the edge of the plate.
Conclusion
In short, the four-roller plate rolling machine is a machine for bending and correcting metal plates, dedicated to the forming and bending of metal plates. The four-roller plate rolling machine has advantages such as automatic material alignment, precise clamping, plate feeding, and one-time rolling.
