At the selection time of press brakes, many contemplate 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 numerous important features needed to reach high-performance bending. Hence, regardless which tool you intend to choose it is important that it meets at the very least a few requirements. Below are a few important things to consider while choosing press brakes.
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 press brake, you will be able to reach part accuracy without the shimming and other tweaks. Amada Press brake parts provides you with the mandatory high precision work.
It allows constructing of numerous lengths out of several pre-cut pieces. The tiny pieces are safer and an easy task to handle.
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 position before you apply the clamping pressure.
As you apply the clamping pressure, punches would be mechanically pulled up into the position. It’d eliminate the necessity to punch into the die throughout the setup.
It is important to be able to install tools from the leading end of the machine. It’d shorten the setup process as you would no longer need to invest time pushing tools from the end of the press brake. Generally, 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 typical position & are constructed of the exact same height. Consequently, you can add off-the-shelf pieces and ensure that they match with existing tools.
There are numerous high-quality tools are constructed in line with the metric standards. So, you will need to get into details to choose the correct tool.
To be able to get the worth for your money, it is important to decide on the very least quantity of lower dies which cover the metal thicknesses which your shop forms.
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 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 bear in mind whenever you choose your V dies may be the flange length. Many sheet metal designers save metal by specifying a flange which is too short such as a 0.5-in. To be able to attain an ideal bending results, it is important to truly have a flange which is at the very least 0.77in.
When forming three and four sized boxes, it is important 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 important to decide on a punch which is tall enough to span the box height diagonally.
