Hybrid Press Brakes and Electric Press Brakes
Hybrid Press Brake Technology:
In the early 2000's a new technology for driving the press brakes ram emerged: Hybrid Technology. Hybrid drive systems in press brakes is somewhat like that of a hybrid car. There is a mix of electronic and hydraulic systems that allow the machine to be much more responsive while maintaining a higher degree of accuracy than a traditional hydraulic press brake system. Reducing cycle times by 30% or more while maintaining a high degree of accuracy these systems.
These hybrid electric machines positioning accuracy demand a tighter tolerance and more precise tool and thus require precision-ground tooling as well as a large clamping area (like New-Standard style Wila tooling) for any kind of assured repeatable performance.
Other advantages of Hybrid Technology Press Brakes:
Green. Up to a 60% energy savings while in standby and a 45% savings during forming with a likely total of 60% savings over one hour with 15 press cycles. That’s a very big deal when you are looking at saving energy and operating costs.
Quiet: when it’s in standby mode and not moving, the hydraulics are not running
Oil (Less - well almost): A great benefit is the reduction in size of the hydraulic oil tank.
Accurate: Because each side of the Hybrid press brake is independently operated by its own hydraulic system, It is an oil on demand direct drive system. It’s very fast, accurate and repeatable.
Affordable: While still not the least expensive option, the Hybrid brake technology allows for a more efficient design and therefore a system costing less than some if its full electric counterparts.
Flexible: Large Range of Tonnages available
Full Electric Press Brake:
Some of the newest technology is the all electric press brake bending machines. These systems are very Fast and efficient, utilizing electric motors that drive the ram up and down. These electric drive systems can be attached directly to a drive screw (like the original Toyo-Koki designed machines) or by way of a timing belt (like the Safandarly E-Brake Design). Although limited in tonnage to under 300 tons currently due to electrical servo motor design constraints, some manufacturers have added a series of pulleys as a force multiplier to their design (i.e. Safan E-Brake). This mechanism also reduces the need for a crowning or other anti deflection table.
Like the Hybrid designed machine, these electric machines accuracy demand a tighter tolerance tool and thus require precision-ground tooling for any kind of assured repeatable performance. These machines have bring some innovative and new features like:
Electric Power: No oil = No oil cooling, No oil filtration and No oil mess!
Lower Energy Consumption: Up to 50% less than hydraulic press brakes
Precise: High Precision
Fast: High speed (up to 35% faster than hydraulic systems).
Quite: Less noise with no hydraulics whining away.
Less Maintenance: Less is More when it comes to maintenance costs.
Eco Friendly: Less power consumption combined with an oil less design make they all electric design very Eco-Friendly.
Whether its Hydraulic, Hybrid or Electric driving the force behind your metal press brake bending machine, your only goal is just make quality parts in the least amount of time.
