In
current industry usage, there are three types of press breaks:
- Mechanical press brakes
- Pneumatic press brakes
- Hydraulic press brakes
These mechanical presses make use of crank mechanism that features a
compartment with energy wheel drive. With pneumatic and hydraulic presses
using air pressure and pressure of hydraulic oil as energy source, pneumatic
press brakes take small area in field of sheet metal and find main usage in
industrial sites, where production processes does not require great efforts.
These hydraulic presses are well characterized by different parameters such
as:
- Force and the working length
- Amplitude
- Distance between frame uprights
- Availability of device deflection compensation table
- Availability of additional accessories enhancing productivity of work
- Support for the work piece
With mechanical and pneumatic presses dominating industries initially,
the current developments made in the field of technology have seen hydraulic
presses starting dominating the market.
Besides high process reliability, lower level of risk of staff injury and
low energy consumption, these hydraulic presses provide several advantages
over mechanical and pneumatic presses. These include:
- Graphical user interface with possibility of automatically
calculating bending sequence of operations
- Job step program
- Protection of operator control device
- Overload protection devices
- Possibility of electronic adjusting speed of progress of cross-beams
- Use of additional hardware
- Operating synchronously with process of bending front of work piece
support
- Sensor monitoring received angle of bending
- Other custom improvements
