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 lots of important features needed to achieve high-performance bending. Hence, regardless of which tool you wish to choose it is important that it meets at least a couple of 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 particular range press brake, you will be able to achieve part accuracy without the shimming and other tweaks. Amada Press brake parts will provide you with the required high precision work.
It allows constructing of varied lengths out of various pre-cut pieces. The tiny pieces are safer and simple to handle.
With the ram up, you should be in a position 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 will be mechanically pulled up in to the position. It would eliminate the requirement to punch in to the die during the setup.
It is important to have the ability to install tools from the leading end of the machine. It would shorten the setup process as you would no further need to spend time pushing tools from the finish of the press brake. Generally, it would eliminate the necessity for forklifts and overhead cranes.
Various elements like safety devices, back gauge heights, and front arm support remain at a standard position & are constructed with exactly the same height. As a result, you could add off-the-shelf pieces and ensure that they match with existing tools.
There are lots of high-quality tools are constructed in line with the metric standards. So, you must enter details to choose the correct tool.
To be able to get the worthiness for your cash, it is important to decide on the very least quantity 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 tend 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 keep in mind once you choose your V dies may 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. To be able to attain the perfect bending results, it is important to really have a flange that will be at least 0.77in.
When forming three and four sized boxes, it is important to help keep the punch height in mind. In some instances, short punches can develop 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 that will be tall enough to span the box height diagonally.
