Vertical rolling machines, also known as vertical plate bending machines or vertical plate rolling machines, are equipment designed to bend metal plates into desired shapes. These machines are widely used in industries such as shipbuilding, aerospace, automotive, and construction, where precision and flexibility in metal forming are essential.
- Vertical rolling machines typically consist of two primary rolls'upper and precise control over the bending process. This adjustability enables the vertical rolling machine to accommodate various plate thicknesses and bend radii, providing versatility in shaping different metal components.
- The frame and bed form the structural support for the rolls and the metal plate during the bending process. These components are designed to withstand the significant forces involved in bending thick metal plates.
- Vertical rolling machines commonly utilize a hydraulic system to apply force to the rolls. This hydraulic system ensures a uniform and controlled bending process, allowing for accurate and repeatable results.
- The hydraulic system also facilitates adjustments to the pressure exerted on the metal plate, accommodating different material types and thicknesses.
- The control panel serves as the interface for operators to input bending parameters. It allows for adjustments in roll position, pressure, and other settings, providing a user-friendly way to control the bending process.
The operation of a vertical rolling machine involves a series of carefully coordinated steps to achieve the desired bend in a metal plate:
- The process begins with the preparation of the metal plate to be bent. This involves ensuring the plate is clean, flat, and properly positioned on the machine.
- Operators adjust the position of the upper roll based on the required bend radius and plate thickness. Precise adjustments are crucial to achieving the desired curvature in the final product.
- The metal plate is then fed between the upper and lower rolls. The hydraulic system is engaged to apply pressure evenly across the width of the plate.
- As the hydraulic system applies force, the upper roll descends, bending the metal plate around the lower roll. The amount of force applied and the speed of the bending process are controlled through the machine's settings.
- Once the bending process is complete, the plate is carefully removed from the machine. The precision of the vertical rolling machine ensures that the metal plate retains the desired shape and dimensions.
Vertical rolling machines find applications in a wide range of industries, contributing to the production of components such as:
- Cylindrical Shells: Used in the manufacturing of pressure vessels and tanks.
- Conical Components: Ideal for forming conical shapes required in industries like aerospace.
- Pipe and Tube Manufacturing: Vertical rolling machines are employed to shape metal sheets into cylindrical forms for pipe and tube production.

It is a kind of equipment that uses work rolls to bend sheet metal. It can form parts of different shapes such as cylindrical parts and cones. It is a very important processing equipment.
1.1 Working principle
The working principle of the steel plate rolling machine is that the upper roller is at the center of the two lower rollers at a symmetrical position through the hydraulic oil in the hydraulic cylinder to act on the piston to move vertically. And the final gear of the main reducer drives the gears of the two lower rollers to mesh for rotational movement.
The rolled sheet provides torque. The metal plate with flat specifications passes between the three working rolls (two lower rolls and one upper roll) of the plate rolling machine. With the help of the pressing of the upper roller and the rotating movement of the lower roller, the metal plate undergoes multiple continuous rolls to produce permanent plastic deformation, rolled into the required cylinder, cone, or part of them.
1.2 Types
Due to different fields of usage, the types of metal sheet plate rolling machines are also different. From the number of rollers, it is divided into three-roller and four-roller metal sheet rolling machines.
The three-roller is divided into a symmetry three-roller sheet rolling machine, a level-down three-roller sheet rolling machine, an asymmetry three-roller sheet rolling machine, and an upper roller universal three-roller sheet rolling machine. The Shenchong 4-roll hydraulic steel plate rolling machines and asymmetry 3-roll steel plate rolling machines are mostly exporting models, which are sold abroad.
From the transmission mode, it is divided into mechanical and hydraulic. The following describes the characteristics of different types in detail from these two aspects.
Mainly three-roller plate bending machine includes symmetrical and asymmetrical.
2.1 Mechanical symmetry 3-roll steel plate rolling machine
The structure of the machine is 3-roller symmetrical type. The upper roller moves vertically at the symmetrical position of the two lower rollers. It is obtained by the transmission of the screw and screw nut. The two lower rollers rotate through the output gear of the reducer and the lower roller.
The gears mesh to provide torque for the rolled sheet. The disadvantage of this machine is that the end of the plate needs to be pre-bent with other equipment.

2.2 Mechanical asymmetric 3-roll steel plate rolling machine
The structure of the machine is a 3-roller asymmetrical type. The upper roller is the main drive, and the lower roller moves vertically to clamp the plate.
The lower roller gear meshes with the upper roller gear and serves as the main drive at the same time; the side rollers are tilted and lifted. With dual functions of pre-bending and rolling. Compact structure, convenient operation and maintenance.
Includes three-roller and four-roller
3.1 CNC Hydraulic three-roller symmetrical series
The upper roller can be vertically lifted, and the vertical lifting hydraulic transmission is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod; the lower roller is driven by rotation, and the output gear meshes through the reducer.
To provide torque for the coil, there is an idler under the lower roller, which can be adjusted. The upper roller is in the shape of a drum, which improves the straightness of the product and is suitable for ultra-long tanks with various cross-sectional shapes.
3.2 CNC Hydraulic four-roller symmetrical series
The position of the upper roller is fixed, and the lower roller moves upward linearly to clamp the steel plate. The rollers on both sides move in a straight line or arc to move closer to the roller to adjust the radius of curvature of the roll.
The four-roller and three-roller rolling machines have different roller motion forms, but the working principle is the same, they both use the principle of three-point fixed circle to carry out different radii. However, the pre-bending straight edge and roundness of the four-roller bending machine are better than those of the three-roller.
