PRECUTIONS FOR THE USE OF GS SPRINGS GUIDE Precautions for the use of gas springs If a gas spring is used under any of the conditions listed elow, explosion of the spring or other malfunction may result in a major accident or in product troule. e sure to read the following precautions efore using gas springs. Danger prevention Never disassemle, weld, fuse, heat, or modify gas springs. Gas springs contain high-pressure gas. Failure to oserve this precaution may cause the internal parts to urst out. Gas recharge and pressure adjustment are not possile. ttempting to do so may cause the spring to explode or result in other major accidents. The operating environment temperature range temperature around the die is 4. Use gas springs only within this range. If gas springs are heated to 7 or higher, the spring may explode or other major accidents may occur. Even if a major accident does not occur, the heat will deteriorate the gas seal, possily resulting in gas leakage. clearance of approximately 1mm on each side of the spring is recommended in order to dissipate heat and prevent contact with the mounting holes. Disposal method Wear protective goggles and discharge the gas from the cylinder efore disposing of the spring. Cut the mounting olt hole all the way through and verify that the nitrogen gas is discharged completely efore disposing. Preventing gas leakage Do not use gas springs under any of the conditions listed elow. Failure to oserve these precautions may result in gas leakage and other prolems. Moreover, a spring explosion or other major accident may occur. Conditions of use that may cause prolems Resulting prolem Consequence a c d e f g h i j n olique load or transverse load is applied. Gas spring is not fi xed with olts. Su-guides are not used or the numer is insuffi cient. The load distriution is not even in all four directions inside the die. There is an ostruction which contacts the gas spring inside the die. The gas spring is fixed in place using the tap hole on the end of the piston rod. n extension pin is mounted on the end of the piston rod. The pressure on the piston rod is not applied to the entire surface. The piston rod contact face is deformed. The piston rod is cut. Eccentric load and/or Spring damage Gas leakage k l m n o p Welding spatter has adhered to the piston rod. Cutting particles or metal particles have adhered to the piston rod. The piston rod is dented. The shot limit is exceeded. large amount of luricant especially chlorine-ased luricant is applied. The gas spring is exposed to moisture, steam or chemicals. Seal damage q r s t u v w x y The gas has een recharged or the pressure has een adjusted. The gas spring is used at high temperatures aove 4 or low temperatures elow. Overstroking The cylinder has een ground. Conditions in which the piston rod is released aruptly. The gas spring is used or stored outdoors, or in a humid location. The gas spring is disassemled, welded, fused, heated, or modifi ed. The gas spring is incorporated in a uilding or a vehicle. Other unintended uses uses other than in a die Loss of duraility Unexpected prolems Gas leakage and/or explosion or other accidents 111
1 2 3 Do not attempt to disassemle, weld, fuse, heat, or modify the product. Gas tank Do not recharge or adjust the gas pressure. Operating environment temperature range 4, gas spring surface temperature 7 or less. Wear safety goggles and discharge gas efore disposal. 4 Contact plate Equivalent to 4HRC 5 6 Do not apply olique or transverse loads. Do not use threaded hole at hole for fastening the spring. Do not use extension pin. lways apply pressure to the entire end surface. Fasten with olts and flange. 7 8 9 Use su guide pins to prevent eccentric loads. Equalize the load. Do not grind the cylinder or cut the piston rod. 1 11 12 e careful of weld spatters, cut particles, and metal particles. Do not exceed the shot limit. Do not apply excessive luricant. 13 14 Overstroking will crush the check pin. 15 Damaged Do not use or store outdoors or at high humidity place. Do not overstroke.

(To adjust the needle valve, insert a hex wrench into the hexagon socket hole for return speed adjustment.) Turn clockwise: The valve closes and the piston rod returns slower. Turn counterclockwise: The valve clearance increases and the piston rod returns faster as the nitrogen gas can quickly move from the auxiliary pressure chamer to the main pressure chamer. ecause the piston rod can e adjusted to return slowly, the workpiece will not e damaged when the piston rod extends during the drawing process. For the mounting plate, HM-5 on P.114 can e used. 123
Structure Needle valve stopper For safety, never touch the needle valve stopper! If the stopper comes off, the needle valve may Hex hole for adjustment jump out of the spring. of return speed Overstroke check pin Valve adjustment Example of use GSSR Special structure uxiliary pressure chamer Needle valve in pressure chamer (Nitrogen gas) Tightening torque should e 5 N cm or less. GSSR When the piston rod descends, nitrogen gas flows into the auxiliary pressure chamer. ecause the nitrogen gas in the auxiliary pressure chamer reduces the pressure in the main pressure chamer, the return speed of the piston rod slows down. Precautions Do not use two or more gas springs on either the die side or punch side. ecause it is difficult to synchronize the return timing of multiple gas springs, the die guide may seize or the die may e damaged. If the needle valve is tightened too much, the valve may e deformed, resulting in malfunction of the gas spring. Do not turn the needle valve stopper. lthough it is onded in place, turning it forcefully may cause gas leakage. The operating environment temperature range is ~ 4. Ensure that the surface temperature of the gas spring does not exceed 7. GSSR can e used without lurication. For the precautions for use, refer to P.111.
