Rolling profile machine

Types of rolling profile machines

A rolling profile machine is industrial equipment used to roll metal sheets into certain shapes. There are several types of rolling profile machines based on the design and the working principle.

• Three-roll rolling machines

  The three-roll rolling machine has three cylinders arranged in a triangular shape. The top-roll, which is the upper cylinder, is adjustable for controlling the product's thickness. The rolling process starts by placing the metal sheet between the rolls. Then, the bottom roll and top roll rotate to carry out the shaping.

• Four-roll rolling machines

  The four-roll rolling machine has two upper and two lower rolls. It works similarly to the three-roll machine but has an additional lower roll. The extra lower roll provides more support to the metal sheet during the rolling process. So, it produces more accurate shapes and compresses the sheet to capacitate it better.

• Section rolling mills

  Unlike the previous rolling machines, the section rolling mill does not have a fixed cylinder. It uses multiple roller frames, each with two rollers. Each frame's roller pairs shape a different section. Once the metal sheets pass through the rollers, they take on the shape of the roller pair.

  The section rolling mill is specific for shaping metal sheets into I-beams, U-channels, angles, and other complex profiles.

• Vertical rolling machines

  The vertical rolling machine has vertically placed rolls. It is suitable for thick plates that don't easily deform. Many vertical rolling machines utilize CNC technology for precise and automatic control of the rolling process.

Specifications & maintenance of rolling profile machines

Understanding the specifications of the rolling profile machinery is important in order to know how to maintain it properly. A bending machine's key features are as follows:

• Machine types: Generally in the profiling rolling machine makers' market, there are three types of machines: the horizontal plate rolling machine, the vertical plate rolling machine, and the angle rolling machine. Each rolling machine will have its own variations and features.
• Number of rolls: The rolling machine has three-roll and four-roll profile rolling machines, among others. The number of rolls affects the accuracy and complexity of the ability to shape materials.
• Roll diameter: The diameter of the rolls determines the maximum size of materials that can be processed.
• Max thickness: This specification indicates the maximum thickness of material that the rolling machine can process.
• Max width: This specification indicates the maximum width of material that the rolling machine can process.
• Material capacity: This specification states the maximum number of plates that can be processed.
• Power requirements: Power specifications usually describe the power and voltage required to operate the rolling machine, including parameters such as AC or DC.

In addition to these specifications, rolling profile machines should also be maintained and taken care of properly by referring to their operating manuals. The following general maintenance recommendations will help keep the rolling machine in optimal working condition:

• Check for loose bolts or parts and retighten if necessary.
• Check machine oils and lubricants for components, latches, rollers, etc., and add the appropriate amounts when required.
• Clean up debris or scraps from the surface of the machine or in the latches to keep it clean.
• Keep the rolling machine polished and lubricated to reduce rust and corrosion for a better operating life.

Scenarios of rolling profile machines

• Construction industry:

  Profile rolling machines are widely used in the construction industry to roll up and make rafter trusses, columns, purlins, eaves, and beams. These machines allow quick and effective production of framework pieces that are strong yet lightweight, which assists in the construction of residential structures, industrial structures, and warehouses.

• Automotive industry:

  The automotive industry utilizes profile rolling machines to assist with the manufacturing of chassis components, roof rails, bumper beams, and other structural parts of automobiles. They are capable of precisely rolling different materials into lightweight yet durable automotive parts. Their high efficiency helps boost productivity within the industry.

• Furniture manufacturing:

  Profile rolling machines can be used in the production of various kinds of furniture, such as office furniture, display racks, entertainment centers, and shelves, among others. Through these machines, cold-rolled steel is shaped into materials for sturdy, ethereal, and modern furniture pieces.

• Shipbuilding:

  In shipbuilding, profile rolling machines assist with the manufacturing of hulls, decks, and other structural parts of the ship. These machines enable efficient production of ship components to boost the shipbuilding industry's productivity, meeting maritime transportation demands.

• Advertising industry:

  In the advertising industry, profile rolling machines are used to produce billboards and sign frames. These machines can quickly and accurately roll various materials into lightweight sign structures and frames to promote brand investment.

How to choose rolling profile machines

Industry buyers and retail buyers can use the following tips when selecting rolling profile machines for sale.

• Determine the target customer base

  Are buyers working with a particular customer base? If buyers are supplying large-scale factories, they should consider machines with a higher capacity. A profiles rolling machine with industrial settings will work better for institutional customers. Conversely, a machine with a more compact design will suit DIYers and small-scale builders.

• Conduct cost analysis

  The upfront cost of investing in rolling machines for profiles is one aspect to consider. First, understand the entire cost of providing the end user. Will shipping costs impact the final price? Will set-up and installation costs increase the final price? The cost analysis will help determine whether rolling machines at different price points match an expected budget.

• Consider the machine's multifunctional ability

  Consider the benefits of purchasing machines that can perform different tasks. A rolling machine with interchangeable parts will provide the flexibility of changing profiles. Users can switch from working with roof panels to walls without investing in a separate machine for each profile.

• Research the selling points

  Industry buyers need to research the reasons for demand in the machine profile rolling market. Determine the machine's selling points, such as automation, precision, speed, and ease of use. Pinpoint the desirable features that customers have mentioned in feedback. Targeting a specific customer base will increase machine demand.

• Assess after-sales support

  Consider suppliers that offer good after-sales support. Supplier after-sales support will aid retail buyers when customers demand extra support for rolling machines. Look for suppliers that provide technical support, spare parts, and accessible manuals. Spare parts catalogs will help retail buyers quickly find required parts.

• Selection of machine materials

  The build of a rolling profile machine impacts its durability and lifespan. Select machines made with tough steel or aluminum alloys. Durable materials ensure the profile machine can handle heavy-duty jobs for several years.

Rolling profile machine FAQ

Q1: What type of roll forming machine makes rounded corners on a profile?

A1: The roll forming machine with a corner rounding station will be able to round off corners on a profile. Buyers can request for customized machines with additional stations to perform other operations such as trimming or filing.

Q2: What type of control is preferred for an automated roll forming machine?

A2: An industrial grade PLC is sufficient to control an automated roll forming machine. The PLC can be programmed to control the speed of the machine and the forming dimensions of the profile.

Q3: How does one know if the machine has sufficient power?

A3: The power requirement can be calculated using a formula, or it can be found in application guides provided by the machine manufacturer. The power requirement can also be determined by conducting a test run on a machine of the same capacity and forming profile.

Q4: Are there any safety precautions when operating a roll forming machine?

A4: Always refer to the user manual and safety guidelines provided by the manufacturer. Ensure that the machine has safety guards installed to prevent any accidental contact with moving parts. Learn about all the features of the machine and how to use or operate them safely before using the machine.
