At the choice time of press brakes, many consider it as a 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 reach high-performance bending. Hence, regardless that tool you intend to choose it is essential so it meets at least several requirements. Here are a few important items to consider while choosing press brakes.
It is essential that the press brake provides high precision work. And for that, Its tolerance ought to be within 0.0004-inch range. With this range press brake, you will have a way to reach part accuracy without any shimming and other tweaks. Amada Press brake parts provides you with the mandatory high precision work.
It allows constructing of varied lengths out of several pre-cut pieces. The small pieces are safer and simple to handle.
With the ram up, you should be able to easily load the tools. It is essential that the tool holding system should hold multiple pieces set up before you apply the clamping pressure.
As you apply the clamping pressure, punches will be mechanically pulled up into the position. It would eliminate the need to punch into the die through the setup.
It is essential to have the ability to install tools from leading end of the machine. It would shorten the setup process as you’d no further need to pay time pushing tools from the end of the press brake. In most cases, 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 made of the exact 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 according to the metric standards. So, you will have to get into details to choose the correct tool.
In order to get the worthiness for your hard earned money, it is essential to select the very least level of lower dies which cover the metal thicknesses which your shop forms.
For many applications in press brakes, in the event that you include high-tensile material, the workpiece might often 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 thin 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 main aspect to bear in mind once you choose your V dies could be the flange length. Many sheet metal designers save metal by specifying a flange that is too short like a 0.5-in. In order to attain the right bending results, it is essential to truly have a flange that is at least 0.77in.
When forming three and four sized boxes, it is essential 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 final bend. Hence, whenever forming four-sided boxes, it is essential to select a punch that is tall enough to span the box height diagonally.
