The field of metal bending underwent a transformation when the press brake machine was developed.
Engineers working on press brakes continued to improve both hydraulic and electric press brakes eventually someone had the brilliant idea to merge the advantages of both of them into a single hybrid machine. Hybrid hydraulic-electric press brakes also called “servo press brakes,” employ hydraulic force to propel the ram and therefore employ AC servomotors to regulate the ram’s angle of motion.
The new brakes made use of an engine, rotor, and unconventional gear to power a ram and contort denser plate material, but they did not replace hand-powered metal press brakes. As a result, completely new fields of manufacturing were made possible. Additionally, as the press brake system advanced over time, increased control and accuracy were added in addition to steadily rising bending power.
Hybrid brakes are far more effective than conventional brakes because they typically require less hydraulic energy and because the hydraulics don’t always operate as they do in conventional brakes. There is no need for hydraulic positional valves, hence there is no space available for valve adjustments. Furthermore, hybrid press brake functioning is surprisingly quiet due to the minimal hydraulic use.
Hybrid press brakes provide reduced production costs due to their decreased power usage, keeping them cheaper for long-term use when compared to their completely hydraulic equivalents.
Going further we’ll discuss 5 main characteristics of press brakes machines.
1. Environmental Protection
Let’s start by examining the benefits of hybridized servo-driven CNC press brakes for reducing energy consumption and minimizing environmental impact. The most sophisticated dual servo pump management system on the planet powers the dual press brake. The conventional servo proportional valve and management technology is replaced by the servo pump. Compared to conventional hydraulic systems, this motor solution uses less space, hydraulic fluid, and power. The quantity of hydraulic oil consumed is only approximately a third or even a fifth of that of conventional hydraulic equipment since the dispersion of fluid is essentially on-demand but without throttle loss. Actual energy savings are possible.
2. Energy Efficient
In addition to energy savings and ecological sustainability, the benefits of hybrid servo CNC press brake machines extend to power utilization and energy conservation are more striking. Since the technology only consumes the power needed mostly by the press brake within every stage and all of the force from the workstation is decreased and compensated, a hybrid press brake has remarkably better energy cost-effectiveness compared to the conventional compression gear mode. It may be decreased by greater than 75%, it may even be down to just 5% of many other systems that are in power-saving mode. The success of this system depends on its location control precision of 5 m. The usage of multiple gearing pumps lowers the overall machine’s noise level. The noise level never exceeds 60 decibels regardless of whether the machine is operating at its greatest speed. The malfunction rate is significantly decreased, and the susceptibility to oil quality is decreased.
3. High Performance
The hybrid servo-driven CNC press brake performs exceptionally well in regards to maximum productivity. Its slider’s or the component’s positional correctness is equal to or even greater than that provided by the proportional valve controller design. The slider’s repeat placement accuracy is 0.01mm following the testing process, with the greatest precision being 0.005mm. To maintain bending precision, its no-load and operating speeds can be raised by 15% to 25% while especially in comparison to a standard CNC press brake machine. The returning velocity can be enhanced by greater than 50%. The production of sheet metal has substantially increased due to the improvement in working speed. This is because of its superior hydraulic system. The fluid temperature may also be maintained at a constant level with the extended quick reciprocal operation. A 38-degree Celsius interior heating is present. The temperature of the liquid doesn’t quite rise above 50 degrees Celsius. Fuel leakage danger is decreased, steadiness is improved, and the lifespan of hydraulic equipment and valves is extended.
4. Automated Operations
In contexts of software features, hybrid servo-driven CNC press brakes can easily and quickly pick tools, determine initiatives, bend robotic arms autonomously, detect lasers electronically, provide input and recognize monitoring results conveniently, among other things. Normal press brakes can also automatically compensate. A hybrid press brake has been able to operate in a manner that is truly autonomous as compared to anti-collision management. The setup is also less confusing since it doesn’t require complicated assembly processes like engines, fuel injection systems, storage cleaning, pipes, etc., which might increase the effectiveness of user installation. Economically and practically speaking, it is better. The previous motor, oil injector, oil chamber, and hydraulic valve switch are retained, along with labor expenses for cleanup and complex pipeline placement. Energy utilization and hydraulic oil requirement are also significantly reduced. The device and it function flawlessly together to create a true automated chemical plant. So even the workplace computer system can be used by the personnel to finish the entire arrangement, slicing, manufacturing, distribution, and completed supplier process, and even then it can take some time and constant labor.
A servo motor is used in the hybrid servo-driven CNC press brake, which is attached to a two-inbuilt gear pump. Both press brake and outgoing fluid stream of the fuel pump are regulated by the CNC technology by regulating the velocity of the servo engine. To manage the slider’s placement precisely, the two canisters are synced to move more quickly and efficiently. The press brake could be attached without the use of oil thanks to the operational program’s direct correlation to the oil fuel tank. This eliminates the need for a transitional pipeline link. The setup is simple, which reduces contamination and other issues while conserving energy and protecting the climate. In the area of industrial production artificial intelligence, multifunctional CNC press brake has already attained Industry 4.0 requirements. It’s a top-of-the-line CNC press brake. It will undoubtedly hold a significant position within the press brake group and within China’s industrial production sector while having a part to play.
