3 Manufactu-red and inspected in accordance with good engineering practice andfall within the PED (Pressure Equipment Directive) stipulated by theCouncil of the European Community. Specifically, Art. 3 of Directive97/23/CE defines, when the fluid volume is > 1dm3 and PS x V is >50 bar x dm3 or when PS > 1000 bar, all gas cylinders must satisfyall requirements defined in Annex I to the European Directive andmust be marked CE .MORE SPRING FORCE IN LESS : one K470-25 compact cylinder dia. (75 mm), stroke .98 (25 mm) against 14 springs, G50x305extra heavy load, dia. (50 mm)with .98 (25 mm) Greater reduction of required surface area, in2(44 cm2)forthe cylinder compared to in2(274 cm2) for the Greater reduction of height, only (135 mm) for the cylin-der compared to (280 mm) for the Greater reduction of volume required, only in3(596 cm3)forthe cylinder compared to 486 in3(7963cm3) for the Greater reduction in the number of retaining devices to pre-load, guide and seat.

4 None for the cylinder compared to 14 forthe Significant cost savings. THE SAME WORKING DEFLECTION IN LESS : one HR300-80 cylinder dia. (32 mm) working deflection (80 mm), total height (190mm) and a final force of 1147 lbs (510 daN) against one B63x305 medium load spring, dia. (63 mm),working deflection (80 mm) as 25% of length for long life, total height of 12 (305 mm) and a final forceof 1165 lbs (517,6 daN). 190mm) 80mm) 305mm) (80mm) Nitrogen CYLYNDERSWHY?BENEFITS- Greater height reduction for the same working deflection Compact tool Significant cost FORCES ON : all Nitrogen springs provide high and known initial forces on contact from 10 lbs ( daN) for the NE16- 220 psi (15 bar) with a body dia.

5 Of M16 up to 27 000 lbs (12 000 daN) for the K 1200 with a body dia. of4,72 (120 mm). Any mechanical wire compression spring requires a pre-load to obtain such initial forces. ( 12 000 daN) (0 daN)BALANCED AND CONTROLLED : Nitrogen cylinders inter-connected by hoses will guarantee a balanced system ensuring equal force ineach cylinder . This is not possible using wire springs since their working characteristics are never exactlythe CYLYNDERSWHY?BENEFITS- No pre-load Easier and quicker Significant cost Consistant force on each contact Forces may be located to exact System may be continually monitored for Consistant production conditionsof Longer life for punches and Significant cost MAINTAINED ALMOST CONSTANT : When cylinders are used in an inter-connected system the forces may be held almost constant, regard-less of deflection, by the use of suitable gas reservoirs or tanks.

6 This is not possible using wire springs sinceany deflection gives a linear increase in Maximum control of parts during forming and drawing Controlled production conditionson Improved parts Significant cost savings. (2 100 daN) (2 300 daN) (700 daN) (100 bar) ADJUSTABLE : The initial force of self-contained (or singly used) cylinders can be adjusted by changing the gas pres-sure while for system operated cylinders , this can be done through a control console max pressure 2175psi (150 bar).Wire springs cannot be adjusted in any way. Nitrogen CYLYNDERSWHY?BENEFITS- cylinders to provide the actual forces Assurance of defined The same cylinder may be re-used for different power Flexible Significant cost Reduction of inventory67 LIFEE xtended lifetime is guaranteed by the construction design and by using only the best materials and components avai-lable.

7 Fundamental features include the treatments NITRIDING AND LAPPING (introduced for the first time by SpecialSprings) on the work surfaces with hardness up to HV 1200and max. roughness Ra..A further advantage of Special Springs SC and H series cylinders is the design with DOUBLE PERMANENT LUBRI-CATION, as well as use of SELF-LUBRICATING GUIDE minimum lifetime of the cylinders , as shown in the relative graphs, is to be considered a guideline only and referto the recommended operating conditions. Obviously cylinder performance can vary considerably according to theeffective operating conditions and correct Do not machine or alter the body or piston Do not apply any shock impact on the sliding surface of the Prevent contaminating solids and aggressive Do not charge with gases other than Nitrogen (N2).

8 - Refrain from loading pressure values over specified maximum. - Always ensure free return of rod after Refrain from working stroke above rated Do not disassemble/maintenance with cylinders under Charge with piston-rod not completely retracted- For optimal performance it is always reccommended to not exceed 90% of nominal Always secure the Always ensure the rod is perpendicular to the contact The rod head must always be in contact with the pressure Pre-load the cylinders by at least .04 (1 mm) when Maximum fluid temperature 176 F (80 C).- Non-aggressive supplementary lubrication of the cylinder initial force (F0) specified for each model refers to standard loading pressure and fluid temperature at approx.

9 176 F (80 C).The final force (F1) specified on the table refers to the average value. The specific graph also illustrates the approxi-mate curve for each initial forces are easily set with loading pressures other than the standard value, and can be calculated as fol-lows:F0= S x P1F0= nominal initial forceS= rod or piston section areaP1= charging pressureMAINTENANCEP ossible on all Special Springs cylinders . For obvious reasons of cost, maintenance is recommended only for cylinderswith diameters equal to or greater than (50 mm).A complete range of special tools and accessories is available for simple and optimal use, to ensure total efficiencywhile restoring cylinders to new conditions also when the working surfaces are re-lapped (procedure always recom-mended).
