Product Description
Characters of high speed cylinder
This Hydro-Pneumatic Cylinder represents a novel technology, where applied two techniques, namely, the speed of pneumatic action and the force developed by hydraulic, It is operated like a pneumatic cylinder and has the press force of a hydraulic cylinder. The changeover from fast to power stroke takes place automatically whenever the working rod hits an oppositing force during its fast aproach...
Operates only on shop air, without hydraulic power units. The controls are very simple, the same as for any double acting pneumatic cylinder. The operating stroke is divided into three stages:
1. Air-operated approach stroke
2. Pneumohydraulic powerstroke
3. Air-operated return stroke
Hydro-pneumatic cylinder 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.
Hydro-pneumatic cylinder is designed in the same way as a double-acting 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 of high speed cylinder
With its clever design the Hydro-pneumatic cylinder 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 of high speed cylinder
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 JLCA-3T with a piston rod diameter of 20mm and a nominal pressure of 6 bar, for example, this contact force is 90kg; Switchover from fast stroke to power stroke is therefore initiated at a counterforce of 90kg. 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 Hydro-pneumatic cylinder 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 of high speed cylinder
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 Hydro-pneumatic cylinder 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.
