What Are the Different Types of Press Brakes?

Press brakes are one of the most commonly used machines in sheet metal fabrication. They come in a variety of sizes and shapes, and each type has its own unique benefits. In this blog post, we will explore the different types of press brakes and what they are best suited for. From hydraulic press brakes to CNC press brakes.

we will cover all the basics so that you can make an informed decision about which machine is right for your shop. Our company is named Alternative Parts INC which provides all types of press brakes. Among all of these Amada press brake parts should be the best option for you.

What is a Press Brake?

A press brake is a machine used to bend or fold sheet metal. The bending process starts by clamping the metal sheet between two dies, which are then brought together to apply pressure and create the desired shape.

There are several different types of press brakes, each with its own unique set of features and capabilities. The most common type is the hydraulic press brake, which uses hydraulic cylinders to generate the necessary force for bending.

Other types of press brakes include pneumatic press brakes (which use air pressure instead of hydraulics), electric press brakes (which use electric motors to generate force), and manual press brakes (which rely on human power).

Different types of press brakes

There are several types of press brakes, each with its own advantages and disadvantages. The most common press brakes are:

1. Hydraulic Press Brakes:

Hydraulic press brakes are the most powerful type of press brake and can apply a large amount of force to the workpiece. They are also very precise and can be used to create complex shapes. However, they require a large amount of space and can be expensive to maintain.

2. Pneumatic Press Brakes:

Pneumatic press brakes use air pressure to apply force to the workpiece. They are less powerful than hydraulic press brakes but more compact and less expensive. They can be difficult to control, however, making them less suitable for precise work.

3. Electrical Press Brakes:

Electrical press brakes use electrical resistance to generate heat, which is then used to bend the workpiece. They are more precise than pneumatic press brakes but not as powerful as hydraulic press brakes. They are also more expensive than pneumatic press brakes.

What are the Advantages and Disadvantages of Each Type of Press Brake?

As I told you earlier, there are three main types of press brakes: hydraulic, pneumatic, and electric. There are advantages and disadvantages for each type.

Hydraulic press brakes are the most common type. They are extremely versatile. You can use them for almost anything and everything, for varied purposes. However, they require a lot of maintenance and can be quite expensive to operate.

Pneumatic press brakes are less common than hydraulic press brakes. They are typically used for lighter-duty applications. Pneumatic press brakes are cheaper to operate than hydraulic press brakes but they require a constant source of compressed air.

Electric press brakes are the least common type of press brake. They are typically used for very precise applications where accuracy is critical. Electric press brakes are more expensive than hydraulic and pneumatic press brakes but they offer the highest level of precision.

How to Choose the Right Type of Press Brake for your Needs?

There are a few factors you'll need to consider when choosing the right type of press brake for your needs.

• The first is the tonnage, or how much force the machine can exert. You'll need to know the thickness and material of the workpiece to determine the tonnage required.
• The next factor is bed size, which will dictate the maximum length and width of the workpiece that can be processed.
• Finally, you'll need to consider stroke length, which is how far the ram can move down to apply pressure.

Press Brake Machines: Types, Advantages, and Disadvantages

Initially the press breaks were made from custom cast iron, oak and a manually operated leaf that would force a clamped piece of sheet metal to be bent. Fast forwarding to today, the making of press brakes has highly evolved with advanced computer technology and hydraulic systems. That is why press brakes these days can easily, efficiently, and safely bend the sheets.

Press brakes work with a die and punch that are set at a particular angle to bend or cut the metal in various shapes and forms. The total pressure that can be applied during the bend is known as tonnage. The higher the tonnage, the thicker the material can be bent.

So for proper fabrication the material size and thickness, tonnage and bending length are required. These factors will determine the load limit of the press brake and it is calculated in tons per inch.

Now, let us understand the types of press brake machines and later on some advantages and disadvantages of it.

Types of Press Brake Machines

A lot of things have changed in the press brakes mechanism over time. Modern press brakes require less effort and are much safer compared to earlier models. Also, modern brakes have improved speed, efficiency, and quality of bending metals. There are three types of modern brakes namely manual, hydraulic, and CNC press brakes. 

Manual Press Brake

Manual press brake is the most common type of press brake and is also called sheet metal brake. They require manual adjustment of bending dimensions and angles. The manual break consists of a worktable, supporters and a clamping plate. Supporters consist of a base, pressure plate and the worktable is mounted on it.

However, manual press brakes are more complex to operate compared to other press brakes as all the adjustments in it are done manually. So, once the bending size and angles are confirmed then only you can start mass production. And then, after completing the first batch you can do new adjustments and start the production again. 

Hydraulic Press Brake

These brakes utilize two hydraulic cylinders and it provides consistent strokes and more control. 

They can be classified based on the types of movement:

• Up Acting

• Down Acting

These are also classified based on synchronization:

• Electro-Hydraulic Synchro

• Torsion Synchro

• Hybrid

CNC Press Brake

These brakes have the highest precision and customization ability. It utilizes computer technology to increase the efficiency and also control the accuracy. The adjustments like bending angle, width, plate thickness, and number of pieces are inserted on a controller by an operator. 

Once the machine starts it does the rest of the things. CNC press brakes generally adopt a hydro-electric servo system and a grating ruler. It consists of a machine frame, workbench, oil cylinder, CNC controller, and hydraulic proportional servo system.

Some parts of the press brakes require replacements after it is worn-out. It is wise to replace such used press brake parts on time or else it will affect the performance of the machine. You can easily find trumpf press brake parts, amada press brake parts, accurpress press brake parts, etc. online.

Advantages

• The press brakes are suitable for small batch and multi variety production. One die set is used to complete the production of some parts and materials that possess strong applicability.

• The shelf life of each set of die is long and the manufacturing cost of bending the die is low.

• It can do the production of S and U shapes.

• It is easily adaptable to new products, without increasing cost.

• It can complete the multibend production of shapes like polygon.

• It adjusts deflection compensation value so that bent is in a straight line that too without manual adjustments. Thus it is simple to handle even a long workpiece.

Disadvantages

• The thickness of the material required to be formed must not be more than 50 mm.

• It can fracture or crack material during bending due to the oxide layer formed at the edges and corner during cutting.

• It can produce large indentation while bending due to inappropriate die and can increase cost.

• Sometimes the materials slip or do not move as they should while bending resulting in material failing to meet the process standards.

 

Conclusion

Press brakes serve a wide range of industries like auto, aviation, energy, agriculture, transportation, military and many more. The production needs and material defines the type of brakes required for proper forming. You can choose one that we discussed above as per your needs. Also, you will require to change used press brake parts that need replacement. Ensure to buy those from the respective brands only. You will easily find amada press brake parts, trumpf press brake parts, etc. online.

Important Rules to Consider While Choosing Press Brakes

At the selection time of press brakes, many consider it as a minor accessory in metal forming and don’t pay enough attention. As a matter of fact, press brakes have transformed into multiaxis, high-precision machines with enhanced features. But only the tooling touches the part while bending.

There are many important features needed to achieve high-performance bending. Hence, regardless of which tool you want to choose it is important that it meets at least a few requirements. Here are some important things to consider while choosing press brakes.

High Precision:

It is important that the press brake provides high precision work. And for that, Its tolerance should be within 0.0004-inch range. With this range, you will be able to achieve part accuracy without any shimming or other tweaks. Amada Press brake parts will give you the required high precision work.

Segmented sections

It allows constructing of various lengths out of numerous pre-cut pieces. The small pieces are safer and easy to handle.

Self-retaining installation

With the ram up, you should be able to easily load the tools. It is important that the tool holding system should hold multiple pieces in place until you apply the clamping pressure. 

 

Self-seating

As you apply the clamping pressure, punches would be mechanically pulled up into the position. It would eliminate the need to punch into the die during the setup.

Front Loading

It is important to be able to install tools from the front end of the machine. It would shorten the setup process as you would no longer need to spend time pushing tools from the end of the press brake. In most cases, it would eliminate the need for forklifts and overhead cranes.

Standard sizes

The common and light tools can reduce the requirement for machine adjustments when changing the project. Hence, it is important to choose tools with standard sizes. You can try searching “Amada press brake parts” in order to find suitable & high-quality products according to your requirements. You can also search for “used Amada press brake for sale” to get the best deals on the internet in case of a tight budget. Various elements like safety devices, back gauge heights, and front arm support remain at a standard position & are made of the same height. As a result, you can add off-the-shelf pieces and make sure that they match with existing tools.

There are many high-quality tools are constructed according to the metric standards. So, you will have to go into details to choose the correct tool.

Die Selection

In order to get the value for your money, it is important to choose a minimum amount of lower dies which cover the metal thicknesses which your shop forms.

Punch Selection

For some applications in press brakes, if you include high-tensile material, the workpiece might tend to crease, crack or even split in two while you use common industry bending standards. Hence, narrow tip exerts force on the bend line. And after combining that with a narrow V-die opening, the forces rise even more. In challenging applications, when material thickness is above 0.5 in, it is important to consult your material supplier on the acclaimed punch tip radius.

Minimum Flange Length

The most important aspect to keep in mind when you choose your V dies is the flange length. Many sheet metal designers save metal by specifying a flange which is too short like a 0.5-in. In order to attain the perfect bending results, it is important to have a flange which is at least 0.77in.

Punch Height

When forming three and four sized boxes, it is important to keep the punch height in mind. In some cases, short punches can form three-sided boxes if the formed side can hang off the side of press brake during the final bend. Hence, whenever forming four-sided boxes, it is important to choose a punch which is tall enough to span the box height diagonally.
