1. How Arc Rolling Machine Works
Symmetrical three-roller mechanical arc rolling machine is a commonly used plate rolling machine. It is mainly composed of an upper roller and two lower rollers. The upper roller is the main driving roller, which can move up and down; and the two lower rollers are also powered (but do not provide main driving force) and can move horizontally.
When the aluminum plate is fed into the gap between the upper and lower rollers, the upper roller moves down and contacts the surface of the aluminum plate. At this time, the upper roller moves downward while rotating. With the increasing downward displacement of the upper roller, the friction between the upper roller and the aluminum plate is also increasing. At the same time, the aluminum panel is subjected to the positive pressure generated by the upper roller and the horizontal friction between them. The positive pressure causes the aluminum plate to bend and deform; the friction makes the aluminum plate rotate rigidly along an arc. In this way, the plate achieves the purpose of rolling deformation. After many such rolling deformations, the aluminum plate can be finally processed into an arc shape with a certain radius of curvature.
The three-roll mechanical arc rolling machine used by Alumideas is equipped with a numerical control system. After the workers load the material, they only need to input the aluminum plate data of the customized aluminum plate, and the machine will automatically operate according to the data. At the same time, experienced workers are also equipped in each three-roll mechanical arc rolling machine. The workers will decide whether to reprocess the aluminum plate on the spot according to whether the aluminum cladding panel meets the customer’s standard, which greatly reduces the occurrence of product errors.
2. Parameters of Arc Rolling Machine
Maximum Width: The maximum width that can be processed by the arc rolling machine is 2500mm.
Maximum Thickness: The maximum thickness can reach 8mm, which is enough to cope with most common aluminum panel sizes on the market.
Power: The power of the main motor reaches 11KW, which can provide enough power for the operation of the machine.
Speed: The rolling speed reaches 4.5m/min, which greatly improves the work efficiency and shortens the production time. That’s why Alumideas can provide you with a wide variety of customized aluminum cladding panel in a short period of time.
Diameter of upper roller: The upper roller of the three-roll mechanical arc rolling machine determines the thickness and diameter of the panel that can be rolled. The diameter of the top roller of the three-roll mechanical arc rolling machine used by Alumideas reaches 240mm.
Diameter of lower rollers: The diameter of the lower roller determines the support strength of the plate. The three-roll mechanical arc rolling machine used by Alumideas has a lower roll diameter of 200mm. It can effectively support the aluminum panel to be fixed between the upper and lower rollers of the machine during processing, and avoid large errors in aluminum cladding panel process.
Distance between lower rollers: The distance between the centers of the two lower shafts is 300mm, which is a moderate distance in a three-roller mechanical arc rolling machine. The greater the distance between the centers of the two axes, the greater the elastic deformation of the aluminum plate, and the change in the cut-in angle and the degree of compression of the aluminum cladding panel. In this situation, the aluminum cladding panel is not easy to deform. If the distance between the centers of the two lower shafts is too small, the aluminum cladding panel will be easily deformed during processing.
3.Features of Three-roller Mechanical Arc Rolling Machine
- Largemotor powerand high work efficiency shorten the production time.
- The numerical control systemmake sure that the aluminum cladding panel required by the customer can be accurately produced, and the errors of manual operation can be reduced.
- The whole arc rolling process is almost automatic, only manual loading and unloading arerequired, which effectively ensures the safety of workers.
- With multi-speed control and multiple flexible control methods, it meetsthe requirements of various complex working conditions.
