speedPOWER – Introduction Pneumohydraulics speedPOWER is the name of the new generation of power cylinders for press and plant engineering applications. The cylinder is used when high forces are required, for example for punching, splitting, pressing, stamping, molding, riveting, clamping, compressing or spot welding. In power stroke mode users are provided with many times the force of a comparable conventional pneumatic cylinder with the same air consumption. speedPOWER is designed in the same way as a doubleacting pneumatic cylinder and is also controlled in the same manner. It is equipped with a pneumohydraulic pressure booster which generates a power stroke when necessary depending on the counterforce. The power cylinder can be operated directly from the compressed air network by means of a pneumatic valve.

Simple operation With its clever design the speedPOWER can be controlled in the same manner as a double-acting pneumatic cylinder. In contrast to conventional power cylinders, switchover from fast stroke to power stroke takes only approx. 0.05 seconds, without venting noises and without requiring an additional valve.

Tool-conserving operation Positioning of the operating piston with the tool on the workpiece is extremely precise and therefore protects the tool, as only the surface of the piston rod is effective due to the design of the device with its freely-actuated operating piston. On version SPK80 with a piston rod diameter of 20 mm and a nominal pressure of 6 bar, for example, this contact force is 190 N; switchover from fast stroke to power stroke is therefore initiated at a counterforce of 190 N. The operating piston is hydraulically damped when it is pushed into the high-pressure sleeve and moves smoothly without jerking.

Switchover from fast stroke to power stroke is unnoticeable. While conventional pneumatic cylinders „shoot through“ at full power, for example during punching operations, the speedPOWER gently makes contact with the workpiece with a low force and then builds up the full power.

Machining workpieces with varying heights does not pose a problem, as the power stroke is only generated when a corresponding counterforce is met at any position throughout the overall stroke.

Short flow path The pressure booster and fluid reservoir are carried along during fast stroke and power stroke to ensure a favorable flow and hydraulic interaction. This enables the use of a highly viscous hydraulic oil which minimizes oil leakages.

The newly patented speedPOWER is an alternative to high-volume pneumatic systems, pure hydraulic systems and mechanical actuators. Various sizes are available for different power ranges and stroke lengths.

With its variable power stroke and fast stroke, the speedPOWER is suitable for universal applications. The operating piston is extended in fast stroke mode until it makes contact with a counterforce. The power stroke is initiated when a speciďŹ c counterforce – depending on the size of the device – is generated. The high-pressure sleeve is pushed further over the operating piston. The high-pressure chamber is closed and a high pressure builds up.

During this advance motion the oil is forced from the annular area into the operating piston area. Power stroke and fast stroke are interactive and form the operating range of the speedPOWER cylinder.

We guarantee first-class quality in system design and supply customized solutions for special applications for cylinders, rotary actuators, for system technology and hydropneumatic applications and for compressed air dryers. You too can profit from the advantages of our own products or the wide range of commercial fluid engineering products. Your satisfaction is our most important concern when giving advice and in the selection of the right products.

Hydropneumatic systems Pressure boosters, air-oil actuators, flow control valves and hydropneumatic cylinders enable maximum movement sequences. The HPE hydropneumatic feed unit sets new standards as an integrated, individually controllable and regulated actuator for tool and packaging machines as well as for process and handling technology applications.

Valves with manual, pneumatic and electrical actuation, are distinguished by high flow capacities, compact design, long service life and a high level of functional reliability, even under extreme conditions.

Flow and pressure regulators round off the control valve range.

Application-based system technology

Proportional controllers

We are very versatile in the design and construction of fluid engineering systems in the fields of compressed air generation and conditioning, and also for actuation, control and movement applications.

The range includes pressure controllers with connections ranging from G 1/8“ to G2“ with pressure ranges from vacuum to 70 bar, positioners for universal applications for pneumatic linear and rotary actuators as well as flow controllers with an integrated flowmeter system. All controllers are of robust design and cover a wide range of analog and digital communication requirements. More information is available at www.ribapneumatic.de

Cylinders for pneumatic and hydraulic actuators are designed, tested and manufactured in inexpensive standard series and also customized versions. High engineering standards combined with a great deal of manufacturing versatility enable optimum solutions even for extreme requirements.

Silencers Various adaptable systems reduce noise and sound level values in high-frequency ranges and extend the separating options for oil particles without impairing flow performance or causing reactions in the control circuits. Small silencers also optimally fulfill requirements of small consumers.

Rotary actuators

Compressors

are used for a very wide range of mechanical engineering and jig construction applications due to their compact and robust design, high efficiency and long service life and low maintenance requirements. These devices are characterized by versatile design with effective accessories.

meet the highest demands in the generation of oilfree compressed air and are designed as piston and diaphragm compressors for low flow rates.

They are very compact, have low maintenance requirements and suitable for continuous operation.

The devices are also available for fully automated operation mounted on a compressed air vessel.

Compressed air motors

Compressed air conditioning

are an inexpensive solution for difficult actuation problems and can be run in any position in reversing mode. The adaptable 8-lamella compressed air motor, the simple geometry of the individual components and the reliable power supply enhance operational safety and ensure low maintenance costs.

The standardized, compact DRUMAG modular pressure conditioning devices feature excellent control and flow characteristics and a high standard of reliability and safety. They can be combined and easily fitted, serviced without tools and feature a wide range of accessories.
