What Is a 4 Roll Plate Bending Machine?
A CNC 4 roll plate bending machine is a type of metal sheet bending and straightening machine, specially designed for metal sheet forming and bending. It can complete various specifications of cylindrical and arc-shaped workpieces' pre-bending and edge rolling with one feeding. With the help of auxiliary devices, it can also roll conical cylinders and be used for rough shaping of metal sheets. The 4 roll plate bending machine can pre-bend the end of the sheet without the need for other equipment and has a smaller remaining straight edge. Compared with the asymmetrical three-roll plate bending machine, it can roll the workpiece without flipping, which not only improves efficiency and guarantees the quality of the workpiece but also has a simple process, easy operation, and reduces labor intensity for workers.

The 4 roll plate bending machine is an advanced, efficient, and high-precision product that reaches the international advanced level. The specific contents of the two structural advantages of the 4 roll plate bending machine are as follows:
It adopts a unique torque shaft synchronization structure, with high rolling speed and good roundness after rolling.
Both sides of the rollers use planetary swing guiding, and the track of the rollers is arc-shaped. The advantage of the arc-shaped line is that it can obtain the best pre-bending effect, shorter straight edges, and increase the roundness and accuracy of the cylinder. It can reduce the rebound effect of the roll and make the diameter of the roll much smaller (can be used for rolling cylinders with a diameter less than 1.1 times the upper roll diameter), while a linear sliding guide 4 roll plate bending machine can roll cylinders (with a diameter of 1.4 to 1.5 times the upper roll diameter).
The four-roller bending machine operates the lower roller to rise so that the bus bar is slightly larger than the working thickness under the upper roller. Then operate the feed side roller to make the upper bus bar on the same level, and then operate the other side to rise between the upper and lower rollers.
The four-roller plate bending machine feeding: Feed the steel plate horizontally so that the end of the steel plate is in contact with the entire front roller, and then the front roller is lowered to the original position.
The 4 roll plate bending machine tightens the steel plate and pre-bends the end: According to the thickness and material of the steel plate, adjust the pressure of the lower roller circuit within a specific range, operate the lower roller to lift and clamp the steel plate, and start the upper roller to rotate. When the steel plate follows to the bending position, stop the rotation of the upper roller. At this time, the left end of the centerline of the upper and lower rollers should have the necessary clamping length equivalent to 1.5 times the plate thickness. Then, the rear roller is lifted to pre-bend the end of the steel plate.
The four-roller plate bending machine uses the front roll to pre-bend the other end of the steel plate: After pre-bending the left end, lower the rear roller to its original position and start the upper roller. When the steel plate follows the above-mentioned bending position, the upper roller stops rotating. Before the operation, the roller lifts the other end of the pre-bent steel plate and then adjusts the pressure of the two roller circuits left and right.
Four-roller cnc plate bending machine pre-bending: Adjust the front and rear rolls to the corresponding positions required for the work, and start the upper roll for forming and bending.
Four-roller plate bending machine forming and bending: After the bending is completed, lower the bottom roller to a lower position, and then lower the workpiece to a certain position along with the rollers on both sides, turn it over, lift the workpiece parallel to the top roller, and take out the workpiece , and complete a work cycle.
Applications of 4-Roll Plate Rolling Machines
Ship Building
Shipbuilding requires a manufacturer to bend, roll, and curve the metal plates to form the different parts such as ship hulls, decks, bulkheads, and the propeller.
Rocket Shell Fabrication
It is as obvious as it seems. The body of the rocket is cylindrical, the tip of the rocket is a cone, and it also has cylindrical structures that work as boosters. Rockets are expensive, and a manufacturer wouldn’t use less precise or less accurate machines to manufacture them.
Wind Energy
Large poles, big wings, and other inner structures of windmills and win turbines require thick metal plates to be forged in desired shapes. A 4-roll plate rolling machine is a go-to choice for such manufacturers.
Oil and Railway Tanks
These tanks go through extremities of weather and friction due to transport. To build these structures from thick metal plates, services of 4-roll plate rolling machines are utilized at their best.
Key Benefits of 4-Roll Plate Rolling Machines
Easy Operation
The 4-roll plate rolling machine is widely acclaimed among operators for its inherent ease of operation. It is equipped with a secure sheet clamping mechanism which provides continuous support through the rolling process. Even novice operators can achieve precise pre-bending and tapering functions akin to seasoned operators.
Higher Efficiency
A 4-roll plate rolling machine is a big investment. As a workshop owner, you want to make the most out of your machine. With the availability of pre-bending, the received flat end has a small straight edge less than 1.5 times the thickness of a metal plate. Thus, you complete your production in half the time compared to a 3-roll plate rolling machine with the flattest end possible.
Higher Accuracy
One thing that keeps this machine on top of its 3-roll counterparts is the accuracy in the final results of the rolling job. More rolls add to precision and ensure the trajectory of rolling is maintained throughout the cycle. Independent axis present on either side further enhances accuracy and precision.
Cost-Effective Production
The machine's ability to perform pre-bending and rolling in a single pass eliminates the need for separate steps. So, the overall rolling time is reduced. There is no additional handling required. Precise control over the bending process ensures accurate and consistent results, reducing the likelihood of errors or rework. Generally, the waste is generated during post-rolling operations. No post-rolling operations mean no extra waste or cost for metal plates.
Rolling Different Shapes Easily
The additional rolls on the 4-roll plate rolling machine facilitate effortless cone rolling. Angular contact bearings, housed in chocks, enable the bottom and side rollers to tilt. It ensures the precise formation of a compact cone. The 4 plate rolling machine is equipped with a rotating cone shoe. This shoe securely holds the workpiece in position while conducting a rolling job.
Solid Build Quality
The 4-roll plate rolling machine is made of thick steel plates and equipped with premium-grade components. It is required, given how easily a 4-roll plate rolling machine handles a heavy workload. Experienced and expert plate-bending machine manufacturers like us, Himalaya Machinery, use cutting-edge components and parts that can be replaced anywhere in the world. Factory-specific components and parts are best for selling machines in the local area.
Versatility
We kept this benefit for the last as it would fit anywhere. As thin as 2mm metal plates which a 3-roll plate rolling machine would handle nicely, to 150mm, which 3-roll cousins would never, are rolled with precision and accuracy with the help of a 4-roll plate rolling machine.
Precautions For The Use Of Four 4 Roll Plate Rolling Machine
1.When checking the roundness with the sample plate, it must be carried out after the plate rolling machine stops.
2.It is strictly forbidden to lap and overload the steel plate when it is rolled. The operator of the plate rolling machine must stand on both sides of the rolled steel plate. No one is allowed to stand in front of and behind the plate rolling machine (the effective working face of the upper roll). No one is allowed to stand on the plate during rolling to prevent the steel plate from stretching out or falling down and hurting people.
3. The specification of rolled plates shall not exceed the range specified in the equipment operation manual and capacity curve. It is not allowed to adjust the pressure of the upper roll at will. The operator must pay attention to the operation.
4. All rolled plates must be placed in the center of the roll shaft for rolling. Slipping is not allowed during coiling.
5. During the process of steel plate rolling and pressing, the operator must always observe the operation of the plate, and the plate shall not roll off. When the length reaches the end, and the symmetrical rolling exceeds the radius, the operation site in the opening direction is not allowed to enter.
6. When the overturning rack overturns, it must be confirmed that the horizontal direction of the upper roll is in the middle position, and it can only be overturned when the vertical direction is at the highest point. When the upper and lower rolls contact, the upper roll cannot be moved horizontally.
7. When the cylinder is preliminarily welded on the plate rolling machine, the ground wire of the welding machine must be in good contact with the cylinder before welding.
Main Components of 4 Roll Rolling Machine
Base Frame: The base frame provides stability and support for the entire machine. It is typically made of heavy-duty steel to withstand the forces generated during the rolling process.
Top Roll: Also known as the upper roll or the top working roll, this component is responsible for applying downward pressure on the material being rolled. It is usually hydraulically controlled and can be adjusted to achieve the desired rolling force.
Bottom Roll: The bottom roll, also referred to as the lower roll or the bottom working roll, acts as a support for the material being rolled. It is typically fixed in position and provides a counterforce to the pressure applied by the top roll.
Side Rolls: The side rolls, also called the lateral or bending rolls, are positioned on both sides of the top and bottom rolls. These rolls assist in controlling the alignment and curvature of the material during the rolling process. They can be adjusted horizontally to accommodate different material widths.
Drive System: The drive system consists of motors, gears, and transmission mechanisms that power the rotation of the rolls. It provides the necessary torque to drive the rolling process and ensures synchronized rotation of all the rolls.
Hydraulic System: The hydraulic system controls the movement and pressure of the top roll. It enables precise adjustment of the rolling force and facilitates the bending and shaping of the material.
Control Panel: The control panel houses the electrical controls and user interface for operating the machine. It allows the operator to set parameters such as roll speed, roll gap, and bending angle, and monitor the rolling process.
Safety Features: 4-roll rolling machines are equipped with various safety features such as emergency stop buttons, safety interlocks, and protective covers to ensure operator safety during operation.
