4 FIBRO Gas Springs The extensive range of FIBRO Gas Springs constitutes an ideal supplement to and expansion of the traditional programmes of spring elements such als helical springs, disc springs and elastomer units. With their minimal space requirement, Gas Springs close a gap where ever the accent is on accomodation of the utmot force component within a minimum of space or where exceedingly large travel is demanded: FIBRO Gas Springs take care of both demands, even in combination. Their self-contained nitrogen charge makes FIBRO Gas Springs completely autonomous devices. Feeder pipes or storage vessel are not required. Monitoring of charge pressure, however, is necessary in certain special cases. Suitable equipment for in-situ pressure control can be found in the Accessories Section. As long as all mounting detail is laid out with due circumspection, removal and installation of the units presents no problems whatsoever. Instructions are included with every delivery of gas springs. On pages F321 to F 328 a number of interesting installation examples are illustrated in detail. Functioning The pressure medium is a commercially available, environment-friendly nitrogen. FIBRO Gas Springs have a standard charge pressure of max. 150 bar. Depending on spring size and type, this pressure offers initial force ratings of 30 dan to dan. Pressure Build-Up In operation the piston rod enters the spring space whose volume is progressively reduced. The resulting pressure rise can be plotted on the Gas Spring Diagram as a multiplication factor. The spring force is the product of initial force times that pressure-rise factor and can therefore be calculated easily. Working Temperature The spring temperature should not exceed +80 C. Charge Pressure Modification of charge pressure allows variation of the force rating and can be predetermined from the spring Diagram. Installation FIBRO Gas Springs can be used in any installation position. Whether or not external forces act on them when at rest is of no consequence. new All FIBRO Gas Springs meet the requirements of the new Pressure Equipment Directive 97/23/EC. The Pressure Equipment Directive (97/23/EC) has been ratified by the European Parliament and the Council of Europe. The requirements of the Pressure Equipment Directive came into force throughout the EC on 29 May The directive defines pressure equipment as vessels, pipework, safety devices and pressure accessories. In terms of the Directive a vessel is a casing which is designed and manufactured to contain fluids under pressure. It follows from this definition that nitrogen gas springs of all sizes are deemed to be pressure vessels and must in this respect comply with the new Pressure Equipment Directive (97/23/EC) from 29 May f110

5 Maintenance FIBRO Gas Springs were disigned for maintenance free continual operation. It is recommended to oil the piston rod lightly from time to time. Guide- and sealing elements can be exchanged easily and expediciously. They are available as a kit. Each kit comes with detailed instructions for maintenance of FIBRO Gas Springs. Warning Signs These are available on request. The signs should be affixed near the springs in as prominent a position as possible. Warning FIBRO Gas Springs may be charged only with commercial nitrogen gas. Accessories The accessories range for Gas Springs comprises fastening devices, charge- and control units, screw connections for these, and connecting lines for compound installations. FIBRO Gas Springs for Ambient Temperatures of up to 180 C Tooling used in the Rubber- and Plastic Industries often is exposed to working temperatures in excess fo 100 C values also reached in certain other manufacturing sectors. FIBRO has developed gas springs that can stand up to temperatures of 180 C a world first for such conditions. This temperature rating is to be understood as follows: where little heat is generated inside the gas spring because of light working conditions, the external (ambient) temperature can be 180 C max. where gas spring operating conditions are mechanically severe and internal heat generation is considerable, ambient tem-perature should not exceed 100 to 120 C. The carge pressure for this series is limited to 120 bar, owing to the thermal expansion of the nitrogen. This has no influence on the Pressure Rise Factor which therefore remains the same. The work capacity (life span) is at this stage approximately 20 % smaller than that of conventional Gas Springs.

6 Mounting Directions for Gas Springs Mounting Examples Below are the various gas spring mounting possibilities, which differ from model to model F112

7 Mounting Directions for Gas Springs To achieve the best possible service-life and safety from the gas spring, the directions below must be followed. Mounting instructions Secure the gas spring to the tool/machine whenever possible, using the threaded hole(s) in the base of the gas spring or a suitable flange. Never exceed the maximum torque values for the threads in the base of the gas spring: (M6 = 10 Nm; M8 = 24 Nm; M10 = 45 Nm; M12 = 80 Nm) The threaded hole in the piston rod top should not be used for mounting purposes. It is only to be used when servicing the gas spring. Do not use the gas spring in such a way that the piston rod is realised freely from its compressed position, as this could cause internal damage to the gas spring. Make sure the gas spring is mounted parallel to the direction of the compression. Ensure the contact surface of the piston rod top is perpendicular to the direction of the compression and is sufficiently hardened. The gas spring should not be subjected to the side loads. Protect the piston rod against mechanical damage and contact with fluids. We do not recommend the last 5 mm or 10 % of the nominal be utilised. The maximum charging pressure (at 20 C) must not be exceeded as it may effect the safety of the product. Exceeding the gas spring s recommended operating temperature will shorten the service-life of the gas spring. The entire contact surface of the piston rod / piston should be used. Do not remove bottom from spring until all gas pressure has been discharged F113

8 FIBRO Gas Springs The Safer Choice At FIBRO, safety has always been a top priority. Below is what we do to help you provide a safer working environment. FIBRO Safety Features Advice to Gas Spring Buyers Excessive Return Speed Protection System Designed for controlled gas venting through piston rods with integral safety stops and specially designed guides. Excessive Return Speed Safety should have always be a top priority. Therefore, we believe gas springs for metal forming tools should (unless the maximum allowable pressure PS is less than or equal to 0.5 bar) be ordered with the following safety requirements: 1) Piston rods with an integral safety stop. 2) Designed, produced and tested according to Pressure Equipment Directive, PED 97/23/EC for a minimum of full cycles*: at highest allowed charging pressure at highest allowed running temperature for all specified mounting methods** ** including top mount, Type C Flange Mounts, according to ISO Please Note: Unless the maximum pressure is less than or equal to 0.5 bar, all gas springs produced, sold, installed and/or used within the EU should be designed, produced and tested in accordance with PED 97/23/EC Over-Pressure Protection System Pressure Vessel Approval FIBRO Over- Pressure Protection System is designed to vent excessive gas pressure in a controlled manner. Over-Pressure Condition FIBRO Gas Springs are designed, produced and tested according to PED 97/23/EC for full cycles* at the highest allowed charging pressure, the highest allowed running temperature, and for all specified mounting methods. * unless other value stated on the springs Over-Stroke Protection System FIBRO has a developed unique System. The cylinder wall is designed to deform in a predefined way, venting the internal gas pressure in a controlled manner. Over-Pressure Condition Please note!!! The safety features mentioned here have not been realized for all FIBRO gas springs to date. By consulting the respective data sheets, please make certain you have the accurate safety standard of the gas spring available that you are interested in; otherwise, direct your inquiry to FIBRO GmbH l f114
