At the choice time of press brakes, many ponder over 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 many important features needed to attain high-performance bending. Hence, regardless of which tool you intend to choose it is essential so it meets at the very least a couple of requirements. Here are a few important what to consider while choosing press brakes.
It is essential that the press brake provides high precision work. And for that, Its tolerance must be within 0.0004-inch range. With this specific range press brake, you will have a way to attain part accuracy without the shimming or other tweaks. Amada Press brake parts will give you the required high precision work.
It allows constructing of numerous lengths out of various pre-cut pieces. The little pieces are safer and easy to handle.
With the ram up, you need to be in a position to easily load the tools. It is essential that the tool holding system should hold multiple pieces in place until you apply the clamping pressure.
As you apply the clamping pressure, punches will be mechanically pulled up into the position. It’d eliminate the necessity to punch into the die through the setup.
It is essential to have the ability to install tools from the leading end of the machine. It’d shorten the setup process as you would no longer need to spend time pushing tools from the end of the press brake. Typically, it’d eliminate the need for forklifts and overhead cranes.
Various elements like safety devices, back gauge heights, and front arm support remain at a standard position & are made of exactly the same height. As a result, you can include off-the-shelf pieces and be 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 enter details to find the correct tool.
In order to get the value for your cash, it is essential to select the absolute minimum number of lower dies which cover the metal thicknesses which your shop forms.
For some 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 essential 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 could be 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 the perfect bending results, it is essential to have a flange which can be at the very least 0.77in.
When forming three and four sized boxes, it is essential to help 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 ultimate bend. Hence, whenever forming four-sided boxes, it is essential to select a punch which can be tall enough to span the box height diagonally.
