At the choice time of press brakes, many ponder over 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 many important features needed to attain high-performance bending. Hence, regardless which tool you intend to choose it is essential that it meets at the least a couple of requirements. Here are some important items to consider while choosing press brakes.
It is essential 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 attain part accuracy without any shimming and other tweaks. Amada Press brake parts provides you with the mandatory high precision work.
It allows constructing of various lengths out of several pre-cut pieces. The little pieces are safer and easy to handle.
With the ram up, you ought to be able to easily load the tools. It is essential that the tool holding system should hold multiple pieces in place before you apply the clamping pressure.
As you apply the clamping pressure, punches could be mechanically pulled up into the position. It’d eliminate the requirement to punch into the die during the setup.
It is essential to be able to install tools from leading end of the machine. It’d shorten the setup process as you would no longer need to pay time pushing tools from the finish of the press brake. In most cases, it’d eliminate the necessity for forklifts and overhead cranes.
Various elements like safety devices, back gauge heights, and front arm support remain at a typical position & are made of 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 according to the metric standards. So, you must go into details to find the correct tool.
In order to get the worthiness for your money, it is essential to decide on the very least amount 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 while 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 essential 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 will be too short such as a 0.5-in. In order to attain the right bending results, it is essential to really have a flange which will be at the least 0.77in.
When forming three and four sized boxes, it is essential 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 essential to decide on a punch which will be tall enough to span the box height diagonally.
