Rack Roll Forming Machine

Rack roll forming machine is one of the key equipments for production pallet stud, rack shelf, metal frame. It has high efficiency production rate and safe operation.

The Rack Upright Roll Forming Machine is mainly composed of decoiler, leveler, material limiter, punch press, roll forming machine, cut-off device and electric control panel.


Decoiler is a device that unwinds and pays out metal coils or other materials that are being fed into a roll forming machine. This is an essential part of the metal fabrication process, as it helps maintain a consistently tight coil. It also helps ensure that the material is fed into the roll forming machine in a way that will result in the desired product.

A decoiler is typically located at the beginning of a production line. It is used to hold and safely pay off or uncoil the steel strip that will be sent on to the next processing line, such as slitting or tube mill entry also roll forming entry.

The decoiler is usually motorized, but it can be operated manually as well. It is an important piece of equipment that is crucial for the operation of a rack roll forming machine, so it must be carefully chosen based on your production needs and specifications.

This machine is available in a variety of different models, depending on your specific requirements. Some models are designed for lighter materials, while others are meant to handle heavy material.

It is important to choose the right decoiler for your situation, as it can have a significant impact on the efficiency of your manufacturing process. The right model for your application is determined by how often the decoiler will be in use and what types of sheet metal you will be working with.

The decoiler can be powered by an electric motor or it can be manually operated, depending on the manufacturer’s preferences. It can also be fitted with a number of features, such as a speed control system that lets you adjust the speeds at which it unwinds the metal.


The Leveler is the machine that levels the material before the strip goes into the punching press and roll forming. If the material is not leveled, it will have a negative effect on the final product. This is because the material will not be as flat and stable as it should be.

There are many different types of levelers. Some are portable, and others are fixed frame. The one you choose depends on the type of material and your needs.

Some are specialized for specific applications, such as for electrical lamination or automotive stamping. These machines are designed to eliminate coil set, cross bow, edge wave, and center buckle in stamped parts.

These levelers can also be used to control dishing that occurs when stamping large holes in heavy strips. They are able to remove these defects and improve the overall quality of the finished product.

Another important feature of these levelers is that they can be programmed to save current settings and recall them later. This feature helps reduce downtime by saving time and money when the operator needs to change settings.

This is especially useful in a line that will run three or four shifts each day. You don’t want to have to stop and start the leveler every time you feed to length into the shear. This causes excessive wear on the leveler and can leave set marks on cold-rolled surfaces.

Some levelers are designed with a hands-off roll cleaning device, which uses a small coil of cleaning media that is placed between the slowly turning work rolls and then moves back and forth across the face of the rolls. This can significantly cut down on downtime.


Punching is a metalworking process that involves the use of a tool to punch holes into a workpiece. The process is commonly used by manufacturing companies to produce a wide range of products. It offers several advantages over other rack roll forming machine types of metalworking processes, including the ability to create a variety of shapes and the speed at which it can be performed.

Unlike many other processes, punching can be used on both ferrous and non-ferrous metals. Ferrous metals, such as steel, are often preferred due to their strength and durability. However, non-ferrous metals can be just as effective in some applications and can be more cost-effective.

The type of metal used for punching will largely depend on its intended application and the size, shape and design of the product. Some of the most common choices include aluminum, brass and copper.

There are also a number of different die designs that can be used in the punching process. The type of die that is chosen will impact the force that is applied to the material as well as the overall production costs.

Progressive dies are a good option for high-production operations because they allow for multiple shaping without having to change the die. They also have a long life and are less expensive to purchase.

In addition, model transfer punching is a popular option that allows for rack roll forming machine the movement of parts from one station to another without changing the dies. This is useful for pipe applications, frames and housings.

Inline punching and inline bending is a very versatile fabrication process that Johnson Bros. Metal Forming Company uses to produce a variety of roll formed components. The latest automated technology and press design and controls enable the company to perform as many roll formed operations as possible in one or more press dies.

Roll Forming Machine

Roll forming is the process of taking sheet or strip metal and bending it into a specific cross-section. It can create a variety of different shapes and is suitable for many types of materials.

The sheet or strip is fed into the roll forming machine, where it is then pulled through successive forming stations that nudge the metal towards the desired shape. This process can be used to form a wide variety of profiles including open and closed tubular shapes as well as more complex structures.

Once the desired profile is formed, it moves into the cut off station. This section can then cut the sheet to the length specified by the user.

This process is very efficient and can produce long lengths of material in a single run without having to break the piece up into separate pieces or cut off large sections of metal. This saves time and money, especially in larger scale production runs.

The roll forming machine uses rollers that are precision contoured to form the incoming sheet metal into the desired shape. These rollers are powered by a motor that drives the machine through each forming station.

Depending on the specific application, the rollers can be as simple as cylindrical dies or more elaborate machines that can take on complex metal maze-like structures. Ultimately, the finished product emerges onto a roller conveyor for a worker to retrieve.

Some modern roll forming machines are equipped with programmable logic controllers that tighten tolerance levels and minimize errors during the production cycle. This allows for precise cutting and checking of the finished component, which reduces labor costs and waste. In addition, these systems can offer in-line processes such as punching or welding to produce a wide variety of products and assemblies.

Cut-Off Device

A cut-off device is a critical part of a rack roll forming machine. This device allows the machine to produce different types of products, such as distribution boxes or metal enclosures. It also helps with safety.

Typically, this device will measure the length of the product through a counter or an encoder. Then, it will set the position switch at a specific location.

Once this is done, the machine can begin forming the product. This process can be done with a variety of machines, and it can be very precise.

The cut-off device is designed for high-speed production, which means it needs to be able to cut the material to a specified length with accuracy. This is why it is important to work with an experienced engineer who can design and set up the process.

To accomplish this, a cutting system is used that can match the speed of the machine. This will allow the machine to run more smoothly, while still ensuring that the products are produced with precision.

In the past, this was done using a limit switch that was mounted on the run-out table. This switch would contact a limit switch actuator that was mounted on the clutch shaft. This enabled the press to reach line speed and cut the parts with accuracy each time it struck the limit switch.

However, this isn’t as easy to achieve as it once was. This is because the ram of the press was moving down as the die went through, and it was also possible for the press to stop at a non-standard position, which could cause the die to not reach line speed when it struck the limit switch.
