Plate rolls: what are they and how do they work?

Plate rolling is a fabrication method used for rolling metal sheet plates into a desired curved shape, such as cylinders, cones, and arcs. This technique is used by many industries for a variety of applications, such as shipbuilding, aerospace, and automotive manufacturing. To achieve the desired effect, factories use industrial-grade plate rolls &#; a type of sheet metal fabrication machine.

What is Plate Rolling?

The process begins by taking a large plate of flat sheet metal and feeding it into the powerful rolling machine. The sheet is sandwiched between two or more large rollers, which are then used to bend it into the desired shape as it is fed between the rollers. Multiple pass-throughs may be required to get the sheet into the desired shape, or the machine may focus on a specific section during a pass. However, the machine has the capability to generate angled curves, such as the ones required for conical shapes. The plate roll is powered by a drive system that can be either an electric plate roll or a hydraulic plate roll. This process is overseen by a computer control screen located next to the rollers.

Advantages of Plate Rolls

There are several advantages to using plate rolling for metal forming. First, it is a cost-effective way to bend metal into complex shapes. Since the process is done with a machine, it is much faster and more efficient than manual forming. Additionally, plate rolling can be used to form thicker plates than other methods, such as press brakes. However, this will depend on the size and capabilities of the roller. This makes it ideal for heavier applications, such as shipbuilding and aerospace.

The amount of force can be adjusted to the specific needs of the application, which allows for the creation of parts with different levels of thickness and strength, alongside complex and intricate curved shapes. This can be especially useful for applications that require parts with complex designs, such as pressure vessels and tanks. Usually, materials such as steel, stainless steel and aluminium are used with the machine as they are malleable under force and not structurally brittle. However, the process can form and shape metals such as copper and titanium.

Given the mechanical nature of plate rolling operations, it is a reliable process that produces consistent results. The process is done in a controlled environment, which ensures that each part is consistent and meets the exact specifications. This can be beneficial for applications that require parts with a high degree of accuracy and is more reliable than traditional manual methods.

Safety Considerations with plate rolls

When working with plate rolling machines, there are several safety practices that must be considered. First, the operator should always wear appropriate safety gear, such as eye protection and gloves. Additionally, the machine and its components should be regularly inspected to ensure that everything is in working order. Finally, the operator should be aware of the machine&#;s capacity and never attempt to roll a plate that is too thick or too large. If your machine is not functioning well or hasn&#;t been inspected in a while, ACRA Machinery provides industrial machinery maintenance and repair for a variety of sheet metal fabrication machines including plate rolls.

Tips and Techniques for plate rolling

To get the best results when plate rolling, there are several tips and tricks to follow. First, the plate should be placed on the rollers in the correct orientation. This ensures that the plate is bent in the right direction. Additionally, the operator should use a lubricant to reduce friction and make the process easier. Finally, the rollers should be set at the correct speed and pressure to ensure that the plate is bent properly.

Plate rolling is a complex process, but it is an efficient and cost-effective way to create precision parts for industrial applications. The reliability and diverse functionality make it an essential asset to many sheet metal fabrication factories.

You must have seen ships, rockets, oil tanks, windmills, and several other large structures around you or on trips. If you are as curious as I am, you may have always thought about how these large structures are made. For such large metal structures to be made in the desired shapes, metal Plate Bending/Rollings are installed at the workshops and factories.

Plate Bending/Rolling machine operators put the metal plates between the rollers in the machine and set the bending force, which results in bending the sheet in the desired manner. Therefore, if you are planning to enter the metal Plate Bending/Rolling industry, it is necessary to learn what it is, why it is performed and how one can perform Plate Bending/Rolling.

Let&#;s understand Plate Bending/Rolling in detail and also discuss how it is performed using different types of machines.

What is Metal Plate Bending/Rolling?

Metal Plate Bending/Rolling is a process of putting the metal plate into a Plate Bending/Rolling/rolling machine and passing it through the machine. Once the attributes such as the bending force and others are set, the desired shape can be achieved.

As you can see in the above image, the metal plate is between the top and bottom roller. Both rolls rotate at different RPMs and put force on the metal plate to bend/roll it. Yet, this is not the whole process. Let us tell you more about how a metal Plate Bending/Rolling/rolling machine works.

How Does a Metal Plate Bending/Rolling/Rolling Machine Work?

There are 4 crucial steps one must follow in order to achieve desired metal plate shape through a metal Plate Bending/Rolling/rolling machine.

• Setting bending force according to the desired radius

• Placing the metal plate on the table to maintain uniform bending/rolling

• Pre-Pinching/Pre-Bending the tails of the metal plate

• Passing the metal plate through the Plate Bending/Rolling/rolling machine

Step 1: Setting Bending Force on the Plate Bending/Rolling Machine

A bending operator will first assess the workload of the Plate Bending/Rolling/rolling machine. Once they are through the assessment, they decide on the bending force to be applied on the metal plate to bend/roll the machine at desired ID or OD (Inside Diameter or Outside Diameter).

A decision on ID or OD is necessary since that is the result.

Step 2: Placing the Metal Plate on the Table to Restrict Unwanted Movement

When the operator puts the metal plate on the table, it limits the movement of the plate in an unwanted direction. This is necessary since a moving metal plate would be mis-bent during the process.

Step 3: Pre-Pinching / Pre-Bending before Commencing the Bending Process

Pre-pinching or Pre-bending is the process of bending both the tails of the metal plate at the initial stage to achieve the desired radius at tails during the bending. It also helps the operator do minimal process post-bending.

Step 4: Bending the Workpiece through the Metal Plate Bending/Rolling Machine

Now that the metal plate is on the stand with pre-pinching or pre-bending successfully achieved, the operator can place the metal plate between the top roll and the bottom roll(s). The bending process is crucial, and having an experienced operator is helpful for the workshops since Plate Bending/Rolling/rolling machines are a major investment.

Types of Machines used for Performing Plate Bending/Rolling Operations

All around the world, several industries such as shipbuilding, metal fabrication, wind energy, earth moving, metal structures, rocket shell making, oil tanks, tubes and pipes, and thousands of others utilize metal Plate Bending/Rolling machines to make varying sizes of equipment and metal structures.

These are the types of Plate Bending/Rolling/rolling machines that these industries use for performing their Plate Bending/Rolling/rolling operations:

All above types of machines can be classified into two types based on their guideway type:

• Linear Guideway Plate Bending/Rolling machine

• Swing Guideway Plate Bending/Rolling machine

Different industries require different machines according to the workload they want the machine to handle. The choice of the machine also depends on the precision levels and majorly on the skillset of the operators.
