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 numerous important features needed to attain high-performance bending. Hence, regardless which tool you intend to choose it is very important so it meets at the least a couple of requirements. Below are a few important things to consider while choosing press brakes.
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 a way to attain part accuracy without the shimming and other tweaks. Amada Press brake parts provides you with the mandatory 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 very important that the tool holding system should hold multiple pieces set up until you apply the clamping pressure.
As you apply the clamping pressure, punches will be mechanically pulled up to the position. It’d eliminate the requirement to punch to the die during the setup.
It is very important to be able to install tools from leading end of the machine. It’d shorten the setup process as you would no more need to invest time pushing tools from the conclusion of the press brake. In most cases, 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 regular position & are constructed with exactly the same height. As a result, you could add 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 must go into details to choose the correct tool.
To be able to get the value for your cash, it is very important to choose the absolute minimum number of lower dies which cover the metal thicknesses which your shop forms.
For some applications in press brakes, in the event that you include high-tensile material, the workpiece might tend to crease, crack as well as 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 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 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 like a 0.5-in. To be able to attain the perfect bending results, it is very important to really have a flange which is at the least 0.77in.
When forming three and four sized boxes, it is very important to help keep the punch height in mind. Sometimes, 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 very important to choose a punch which is tall enough to span the box height diagonally.
