What is ESA SYSTEM?
EsaBend is an application for the programming and the simulation of a Press Brakes machines with a CNC, used to increase productivity, decrease downtime and reduce material wastage. EsaBend allows offline calculate the tooling
and bending sequence,through a 3D simulation environmentwhere they are checked for collision between the part,Tools feedback and machine components
What is General features?
- Direct import from SolidWorks, Solid Edge e Inventor
- Import and unfolds IGES and STEP 3D parts
- Automatic and manual tool selection based on the type of material,
machine and tools properties
- Automatic and manual bending sequence
with collision control
- Automatic calculation of the back gauges backing
- Automatic and manual back gauge positioning
with interactive graphic controll of all axes
- 3D simulation of the bending process
with collision detection
- Detailed report of tooling stations of the machine which also includes
the bending sequence, the tools used
and the graphic and specific information bend by bend
What is Benefits?
- Automatic features that speed up management time
from design to finished product
- Offline programming which allows minimizing downtime
- Collision control in the bending sequence that allows
a reduction of the material discarded
- Automatic and manual bending sequence
with collision control
- The tools library is compatible with the availability
of tools needed for the production
Efficiency in tool selection
Based on:
- Availability of different types of tools and its fractionation
- Bend radius
- Maximum machine force
- Collisions control
Full crushed fold management
- Definition of default tools crushed fold,
for automatic recognition
- Setting the pre-bending angle,
with default and editable value
Sequence of bend calculation
EsaBend automatically calculates the sequence of bend
taking into consideration the following points:
- Avoid collisions
- Availability of the fractionation of the tools
- Utensili a scarpetta per la gestione delle contropieghe interne
Full manual control:
- Split of complete folds into partial folds,
with the angle definition of pre-fold
- Interactive editing of the order of the bending sequence
Back gauges positioning
EsaBend provides automatic and manual control options
of the back gauge:
- Automatic position back gauge supporting
- Automatic calculation tooling considering the shape of fold
- Graphic and interactive control for all of the axis
- Snap Management on all axes for precise positioning stop
3D Simulation and collision detection
EsaBend comes with real-time, automatic 3D simulation, presenting
a realistic visualization of the bending process. The simulation helps
you to create an error-free process, producing NC code or a bending
report. The simulation lets you check whether the part collides with
the press brake, tool setups, finger-stops, or even with itself. It also
checks whether the finger-stops collide with any of the tool setups,
and whether the punches collide with the dies.
- Real-time animation
- Realistic visualization of bending process
- Dynamic collision analysis (e.g. backgauge movement)
- Detection of collisions between all moving elements
- Operator part handling
- 100% correct program
Tooling report
The complete tooling report includes:
- Bend sequence instructions
- Tool information and tool setup details
- Flat view with the bend sequence
- Product handling
- Bend By bend graphics
Innovative Press Brake Drives
Innovation
In the e-Z Hybrid Servo Drive, servo pumps replace the classic servo/
proportional valve and control technology.
This con cept allows for an optimal adjustment of power and speed to
the bending process and simplifies the design of the press brake, while
minimizing energy consumption.
The new drive solution requires significantly less space and less oil
volume than standard hydraulic systems.
Engineering
In a close collaboration between ESAautomation and Voith, an
optimal product combination was developed for the e-Z Hybrid Servo
Drive.
The intelligent control allows a very flexible use of the press brake and
pushes forward the capabilities of the machine with the available
options for angle measurement and active crowning.
You can benefit from our many years of expertise with regard to
managing complete drive systems.
Our specialists are on hand to support you when it comes to the servo
pump group dimensioning.
Energy
Compared to conventional systems based on se-rvo/pro portional
valve technology, the e-Z Hybrid Servo Drive is energy-efficient,
because the system uses only as much energy as the press brake
requires in the various phases: most of th pressure drop from
bottlenecks have been either eliminated or extremely reduced.
The position control accuracy of 5 μm is a strongpoint of this system.
Compared to conventional press brakes, where the-re is con
tinuous full energy consumption, the e-Z Hybrid Servo Drive energy
consumption is 95% lower in stand-by mode.
Operative costs
The e-Z Hybrid Servo Drive concept implies very high efficiency in
energy consumption; no energy is wasted in oil cooling.
The state-of-the-art CNC provides additio-nal dia gnostic capabilities,
which supports preventive maintenance and, in the ideal case,
condition-oriented maintenance.
The full remote connection is standard in this system.
The OEM can connect from remote with the supplier or with his end
customer.
When the machine is not working the system is complete shut down
and the energy consumption is near to 0%
Acoustic
The e-Z Hybrid Servo Drive achieves the excellence in noise emission.
Thanks to the direct drive of the pumps with the brushless motors,
there is no noise emission in the stand-by phase.
When the ram is moving, the Voith internal gear pump is one of the
quietest available on the market.
System logic
The servo pump meters the oil flow from the cylinder during the high
speed ram fall; once at the exchange point, the servo pump switches
to the cylinder side to perform the working phase.
At the end of the decompression, the servo pump lifts the ram either a
specific distance for angle measurement or to the upper tool position.
Angle measurement panel (optional)
Springback is the biggest issue for air bending, and it gets worse as
material become stronger, affecting setup times, especially for short
runs. In fact, the variations for material thickness, hardness and grain
direction result in angle deviation, slowing production and creating
scrap.
The optional angle measurement control panel lifts the top tool
with high precision to the point where the measurement is made
and enables the ram to repeat the bend after the corrections with a
smooth and precise movement.
Active crowning panel (optional)
During the bending process, the different behavior of each material
results in deformation of the machine components, that can be fully
compensated by using crowning cylinders mounted in the lower
beam.
The optional active crowning panel is able to control precisely in real
time the force generated by the crowning cylinders, correcting the
accumulated machine deformations.
