Aluminium rolling machine

Types of aluminium rolling machines

Aluminum is a type of metal that can be malleable and shaped into sheets, plates, or foils. Aluminum sheets are pressed through a series of rollers to reduce the thickness, increase the strength, and improve the surface finish, a process known as aluminum sheet rolling. An aluminium rolling machine is a critical component used to reduce the thickness of aluminum, typically a 2 or 4-high roll arrangement, which refers to how many rolls are used. The thickness is reduced further, and the surface finish is improved by using more rollers.

Generally, the aluminium rolling machine comprises of a main unit, a motor, a reducer, a flywheel, and a frame. The frame is the basic structure of the machine that is usually made of cast steel and is bolted together. The flywheel is a mechanical device that is used to store rotational energy and helps to smoothen out the operation of the machine. The reducer in the aluminium rolling machine is used to reduce the rotational speed of the motor, and finally, the motor is an electrical device that helps the machine to work.

The type of aluminum rolling machine depends on the roll configuration. The most common types are 2-high and 4-high aluminium rolling machines. A 2-high rolling mill comprises two rolls that are made from steel and are typically stacked horizontally. The metal is inserted into the roll gap, and the rolls are rotated in opposite directions to reduce the aluminum's thickness. The 2-high rolling mill is a straightforward design, but it has some limitations. The work roll is not supported at the center, which means that the metal is not processed uniformly. This causes the metal to have a non-uniform thickness. The metal also tends to twist and bend because the rolls are not supported.

Meanwhile, the 4-high aluminium rolling mill has an extra backing roll to support the work roll. This helps the mill to have a higher thickness reduction and a better surface finish. The 4-high mill is more versatile and can be used to process metal of different sizes and thicknesses. The 4-high rolling mill is also more stable and can handle larger thickness reductions.

The 4-high aluminum cold rolling machine also has the same four rolls, but they are arranged differently. The work rolls are smaller and are located above the larger backing rolls. This mill is used for cold rolling processes where the metal is deformed at low temperatures.

Specification and maintenance of aluminium rolling machines

The specifications of aluminium roll forming machines vary depending on the type and model. Here are some key specifications to consider when sourcing these machines.

• Machine Type: The type of aluminium roll forming machine is a crucial specification to consider. Common types include corrugated, double layer, and roof panel roll forming machines. Each machine is designed to produce specific aluminium profiles.
• Machine Size: The size of the aluminium roll forming machine is determined by the dimensions of the profiles it can produce. Dimensions to look out for include length, width, and height.
• Roller Stations: This refers to the number of rollers on the machine. The number of roller stations can be 12, 14, or more, depending on the design complexity of the final aluminium profile. More roller stations provide better shaping and precision but can increase machine length.
• Roller Shaft Diameter: This determines the strength and stability of the rollers. Larger diameters are preferable for heavy-gauge aluminium, while smaller diameters are suitable for thinner material.
• Material Thickness and Width: The maximum and minimum thickness and width of aluminium material that the machine can process should be considered. The specifications are usually measured in mm or inches.
• Speed: This is the operating speed of the machine, usually measured in meters per minute (m/min). The speed at which the machine can produce aluminium profiles is a key specification to consider.

Proper care and maintenance of the aluminium roll forming machine are important to ensure its longevity and performance. Here are some maintenance tips for this type of machine.

• Regular Cleaning: It is important to keep the machine clean. Remove debris, dirt, and metal shavings from the rollers and other parts regularly. This helps prevent damage and maintain optimal performance.
• Lubrication: Lubricate moving parts of the machine to reduce friction and prevent premature wear. Proper lubrication helps to maintain smooth operation and prevent overheating.
• Inspection and Adjustment: Regularly inspect the machine for loose bolts, misaligned components, or any signs of excessive wear. Make necessary adjustments and repairs to ensure the machine is always in good working condition.
• Electrical System: If the machine has an electrical system, inspect the wiring and connections regularly. Ensure they are secure and free from damage. Also, follow the manufacturer's guidelines when connecting and disconnecting the electrical power.
