At the choice time of press brakes, many consider it as a 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 lots of important features needed to achieve high-performance bending. Hence, regardless of which tool you intend to choose it is very important that it meets at the least a few requirements. Here are a few important items to consider while choosing press brakes.

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

Segmented sections

It allows constructing of various lengths out of several pre-cut pieces. The tiny pieces are safer and an easy task to handle.

Self-retaining installation

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

Self-seating

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

Front Loading

It is very important to manage to install tools from the leading end of the machine. It would shorten the setup process as you would no longer need to invest time pushing tools from the finish of the press brake. Typically, it’d eliminate the requirement for forklifts and overhead cranes.

Standard sizes

Various elements like safety devices, back gauge heights, and front arm support remain at a regular position & are made of exactly the same height. Consequently, you can add off-the-shelf pieces and ensure that they match with existing tools.

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

Die Selection

To be able to get the worthiness for your money, it is very important to select the absolute minimum number of lower dies which cover the metal thicknesses which your shop forms.

Punch Selection

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

Minimum Flange Length

The main aspect to keep in mind whenever you choose your V dies could be the flange length. Many sheet metal designers save metal by specifying a flange which is too short like a 0.5-in. To be able to attain an ideal bending results, it is very important to truly have a flange which is at the least 0.77in.

Punch Height

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