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.
