Servo electric bending technology

Servo electric eP-1030 press brake Prima Power has been a true pioneer in applying servo electronics in sheet metal working. The first punching machine with the green e-technology was introduced as early as 1998. Today this technology is offered in a wide range of products e.g. stand-alone punching machines, laser combi machines, Shear Genius® machines integrating punching and right angle shearing as well as panel benders. Prima Power has now applied a servo-electric drive system on the new eP-Series press brake. It is a fast, accurate, non-hydraulic bending solution. The in- Model eP-0520 eP-1030...

Design concept Pulley-belt force transmission The pulley belt system is actuated by Prima Electro servo drives and dis- tributes the bending force over the whole bending length. The system consists of fixed and moving rolls spread out over the total working length of the upper beam. The belt itself is a steel wire reinforced main- tenance free belt. It is not a tooth-belt, nor is the functioning based on friction, but the entire force is transmitted trough tension - a simple and reliable solution. Servo motor drives offer superior movement con- trol and accuracy. Thermal influences on precision...

The eP-series utilizes the Prima Industrie Group's know-how in control technology and features the Prima Electro Open Control. For maximum process- ing speed this MSWindows based control has two sep- arate processors,one for real time operations and one for bending application tasks An operator friendly 17" Touch Screen user interface leads to a significant improvement of data input rates and a considerable reduction in programming time. 2D graphical programming with automatic bending sequencing will assist in making even first time opera- tors productive. The Prima Electro Open Control has a...

in combining safety and productivity The "Block Laser" safety equipment by Lazer Safe rep- resents the most advanced safety solution for press brakes in terms of productivity and protection level. Its unique features increase the competitiveness of - Speed changeât 2 mm above material - Allows the operatorio safely work close to the tools without interrupting high approaching speed - Tool crash protection - Box mode to achieve complex shapes with no - Fully integrated in the control; different operating modes selectable bend by bend (stop at mute - auto mute - box flange height) - Automatic alignment...

Apart of its outstanding rigidity and stress behaviour the O-frame construction offers big advantages in terms of flexibility. The uprights being mounted out- side the bending length, there is no throat limitations for long parts that is typical with C-frame structures; distance between uprights = maximum bending length! In addition the back gauge system can be used effectively over the whole bending length. A programmable dual drive back gauge is standard on all eP-Series press brakes. Two rigid fingers are pro- vided with manual adjustment along the length of the gauge via linear-guides. Three...

Maximum productivity The eP-Brake features the advantages of high acceleration, deceleration and fast response times of the servo electric drive system. Compared to conventional brakes considerable productivity increase can be reached; reduction of cycle times by up to 30 % and more is the reality. Working speed is programmable to ensure bending is made without loss of prod- uct quality or operator safety. Lazer Safe's "Block Laser" system provides safe high speed closing down to just 2mm. Compared with other guarding systems or even unguarded machines the block laser system can save up to 2...
