Essential Rules to think about Whilst Selecting Press Brakes

At the choice time of press brakes, many ponder over 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 many important features needed to attain high-performance bending. Hence, regardless of which tool you want to choose it is very important so it meets at the very least several requirements. Here are a few important things 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 must be within 0.0004-inch range. With this particular range press brake, you will have the ability to attain part accuracy without any shimming or other tweaks. Amada Press brake parts will provide you with 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 in a position to easily load the tools. It is very important that the tool holding system should hold multiple pieces in position and soon you apply the clamping pressure.

Self-seating

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

Front Loading

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

Standard sizes

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

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

Die Selection

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

Punch Selection

For many applications in press brakes, if you include high-tensile material, the workpiece might often 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 narrow 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 most important aspect to remember when you choose your V dies is the flange length. Many sheet metal designers save metal by specifying a flange which can be too short like a 0.5-in. In order to attain an ideal bending results, it is very important to really have a flange which can be at the very least 0.77in.

Punch Height

When forming three and four sized boxes, it is very important to keep the punch height in mind. Sometimes, short punches can form 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 decide on a punch which can be tall enough to span the box height diagonally.
