The difference between three-roller plate rolling machine and four-roller plate Rolling machine

Plate Rolling machine is a common mechanical equipment in the metal processing industry, used to bend or shape metal sheets. It is mainly divided into two types: three-roller plate rolling machine and four-roller plate rolling machine.

 

Three-stick rolling machine:

- Consists of three rollers, two lower movable rollers and one upper fixed roller.

- The distance between the upper and lower rollers is adjustable to control the Rolling angle.

- Suitable for rounding thin sheets.

- The operation is relatively simple and suitable for small batch production.

Three-roller plate rolling machine features:

The structure of the machine is a three-roller symmetry. The upper roller moves vertically up and down at the central symmetrical position of the two lower rollers, which is obtained by the screw nut and worm drive. The two lower rollers make rotational movements, and the output gear of the reducer and the lower roller The gears mesh to provide torque for the rolled sheet.

Four-stick rolling machine:

- Consists of four rollers, three lower movable rollers and one upper fixed roller.

- The distance between the upper and lower rollers can be adjusted independently, making it more flexible.

- Suitable for bending thick plates.

- Simple operation allows for more precise bending control.

- Suitable for mass production and complex shape bending processing.

Four-roller plate bending machine features:

The position of the upper roller is fixed, and the lower roller moves upward to clamp the steel plate. The rollers on both sides move closer to the upward roller in a straight line or arc to adjust the curvature radius of the drum. The roller movement forms of four-roller and three-roller plate rolling machines are different, but the working principle is the same. They both use the principle of three-point circle determination to roll different radii. However, the pre-bent straight edges and rounded roundness of the four-roller plate rolling machine are better than those of the three-roller.

Summarize:

The three-roller plate bending machine is suitable for simple bending of light and thin plates, while the four-roller plate bending machine can handle thick plates and achieve more complex bending and forming. Manufacturing companies need to choose the appropriate plate rolling machine model according to their own needs.
