At the selection time of press brakes, many consider 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 lots of important features needed to accomplish high-performance bending. Hence, regardless that tool you want to choose it is important so 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 really be within 0.0004-inch range. With this particular range press brake, you will have a way to accomplish part accuracy without the shimming or other tweaks. Amada Press brake parts provides you with the required high precision work.
It allows constructing of numerous lengths out of several pre-cut pieces. The little pieces are safer and an easy task to handle.
With the ram up, you ought to be able to easily load the tools. It is important that the tool holding system should hold multiple pieces in position and soon you apply the clamping pressure.
As you apply the clamping pressure, punches could be mechanically pulled up in to the position. It’d eliminate the need to punch in to the die through 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’d no longer need to invest time pushing tools from the end 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 typical position & are constructed with the same height. Consequently, you can add off-the-shelf pieces and be sure that they match with existing tools.
There are lots of high-quality tools are constructed based on the metric standards. So, you will need to go into 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 level 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 have a tendency to crease, crack or even 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 important to consult your material supplier on the acclaimed punch tip radius.
Minimum Flange Length
The main aspect to bear in mind when you choose your V dies could be the flange length. Many sheet metal designers save metal by specifying a flange which will be too short like a 0.5-in. To be able to attain the right bending results, it is important to truly have a flange which 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 form three-sided boxes if the formed side can hang off the medial side of press brake during the final bend. Hence, whenever forming four-sided boxes, it is important to decide on a punch which will be tall enough to span the box height diagonally.
