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

High Precision:
It is important that the press brake provides high precision work. And for that, Its tolerance must be within 0.0004-inch range. With this rangeĀ press brake, you will have the ability to achieve part accuracy without the shimming and other tweaks. Amada Press brake parts will give you the necessary high precision work.

Segmented sections

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

Self-retaining installation

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

Self-seating

As you apply the clamping pressure, punches will be mechanically pulled up to the position. It would eliminate the necessity to punch to the die through 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 more need to spend time pushing tools from the conclusion of the press brake. Generally, it would 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 typical position & are made of exactly the same height. Consequently, you can include off-the-shelf pieces and make sure that they match with existing tools.

There are numerous high-quality tools are constructed in line with the metric standards. So, you will have to go into details to choose the correct tool.

Die Selection

In order to get the worth for your money, it is important to decide on the absolute minimum level 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 often crease, crack or even split in two as 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 important to consult your material supplier on the acclaimed punch tip radius.

Minimum Flange Length

The most important aspect to remember when you choose your V dies could be the flange length. Many sheet metal designers save metal by specifying a flange that will be too short just like a 0.5-in. In order to attain an ideal bending results, it is important to have a flange that will be at the very least 0.77in.

Punch Height

When forming three and four sized boxes, it is important to help keep the punch height in mind. In some instances, short punches can form three-sided boxes if the formed side can hang off the side of press brake during the last bend. Hence, whenever forming four-sided boxes, it is important to decide on a punch that will be tall enough to span the box height diagonally.
