Faq
Before choosing your press brake, you must first know the type of metal you want to bend (stainless steel, 16 gauge mild steel, etc.)
Then you will need to determine the particular characteristics to be taken into account when calculating the part bend. This includes, for example:
*The tensile strength
*The thickness and length of the metal
*The press brake’s folding or bending length
*The width of the V
*The inner radius of the parts
Once these characteristics have been determined, you must then calculate the tonnage required for the bending operation.
The tonnage is the press force of the press brake. It determines the amount of pressure that can be applied by the punch during the bending operation.
*High tonnage allows thick and hard metals to be bent.
*Low tonnage is suitable for thin metals.
Other your budget also is important factor.
Warning: incorrect tonnage (too high or low) can damage your press brake or the part you are bending. To calculate the tonnage of your press brake, refer to the operating manual or a tonnage table.
What other criteria are important to consider when choosing a press brake?
*The back gauge
This is an adjustable gauge that stops the part by centering the bending line on the V-shaped opening of the die.
It allows the part to be bent to be in the right position.
*The angle control
It is used to compensate for any inaccuracies in the press brake.
Warning: the angle control is limited on some parts (if they are too small, parts with negative angles, etc.).
*Tools
Using hydraulic clamping allows for shorter tool change times, for example.
The clamping length also has an effect on the tool accuracy.
Be sure to respect the maximum press force to avoid damaging to the tools.
*Operator safety
When changing tools, make sure to stop the press brake motor or turn it to minimum.
Operators should never put their hands in the tool work surface.
They must also not wear loose or flowing clothing.
Lastly, operators must not work at the back of the machine.
