3 PRECUTIONS FOR TE USE OF GUIDE Precautions for the use of gas springs If a gas spring is used under any of the conditions listed below, explosion of the spring or other malfunction may result in a major accident or product trouble. e sure to read the following precautions before using gas springs. Danger prevention Never disassemble, weld, fuse, heat, or modify gas springs. Gas springs contain high-pressure gas. Failure to observe this precaution may cause the internal parts to burst out. Gas recharge and pressure adjustment are not possible. 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 Use gas springs only within this range. If gas springs are heated to 70 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, possibly resulting in gas leakage. Disposal method Wear protective goggles and discharge the gas from the cylinder before disposing of the spring. Cut the mounting bolt hole all the way through and verify that the nitrogen gas is discharged completely before disposal. Preventing gas leakage Do not use gas springs under any of the conditions listed below. Failure to observe these precautions may result in gas leakage and other problems. Moreover, a spring explosion or other major accident may occur. Conditions of use that may cause problems Resulting problem Consequence a n oblique load or transverse load is applied. b Gas spring is not fixed with bolts. c Sub-guides are not used or the number is insufficient. d e f g The load distribution is not even in all four directions inside the die. There is an obstruction 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. Eccentric load and/or Spring damage h i The pressure on the piston rod is not applied to the entire surface. The piston rod contact face is deformed. Gas leakage j The piston rod is cut. k Welding spatter has adhered to the piston rod. l Cutting particles or metal particles have adhered to the piston rod. m n o The piston rod is dented. The shot limit is exceeded. large amount of lubricant especially chlorine-based lubricant is applied. Seal damage p The gas spring is exposed to moisture, steam or chemicals. q The gas has been recharged or the pressure has been adjusted. r The gas spring is used at high temperatures above 40 or low temperatures below 0 s t u v Overstroking The cylinder has been ground. Conditions in which the piston rod is released abruptly. The gas spring is used or stored outdoors, or in a humid location.

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 chamber to the main pressure chamber. ecause the piston rod can be adjusted to return slowly, the workpiece will not be damaged when the piston rod extends during the drawing process. For the mounting plate, M- on P.878 can be used. 885

26 Structure ex hole for adjustment of return speed Needle valve stopper For safety, never touch the needle valve stopper! If the stopper comes off, the needle valve may jump out of the spring. Overstroke check pin Valve adjustment Example of use GSSR Special structure uxiliary pressure chamber Needle valve in pressure chamber Nitrogen gas Tightening torque should be 0 N cm or less. GSSR When the piston rod descends, nitrogen gas flows into the auxiliary pressure chamber. ecause the nitrogen gas in the auxiliary pressure chamber reduces the pressure in the main pressure chamber, 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 be damaged. If the needle valve is tightened too much, the valve may be deformed, resulting in malfunction of the gas spring. Do not turn the needle valve stopper. lthough it is bonded in place, turning it forcefully may cause gas leakage. The operating environment temperature range is Ensure that the surface temperature of the gas spring does not exceed 70. GSSR can be used without lubrication. For the precautions for use, refer to P.863.

28 Product data Features of gas springs GSZ and GSC GSZ and GSC use exclusively developed and improved components with the aim of reducing eccentric load that is the main cause of gas leakage, and damage to the components due to friction heat and sliding damage. y combining the four elements that support high durability, allowable eccentricity 1 is realized and durability is substantially improved. 1. igh rigidity Reduce influence of eccentric load since cross-direction force is absorbed by supporting the piston rod at two points. Piston rod Guide Elements of high durability It is structured so that the cross-direction force is further absorbed by forming two layers of piston rod guide. Suppress inclination of piston rod 1, and reduce gas leakage due to eccentric load. 1 llowable eccentricity 1 2. Low heat Suppress heat generation during sliding by smoothening the surface of piston rod. Mirror finishing 3. Wear resistance Protect the high hardness 1000V piston rod from damage due to eccentric load, and reduce risk of gas leakage. 4. igh heat resistance The exclusively developed special gas seal reduces thermal deterioration due to continuous shots. Gas seal after 1 million shots There is no obvious deterioration due to heat generation during continuous shots. Test conditions: test sample GSZ, eccentricity 1, speed SPM, stroke 48mm Durability test results Even after 1 million continuous shots at eccentricity 1, the initial load decrease ratio still remains about 5. 2 Initial load N 4820N 4610N GSZ 4000 Conventional products GSM Test sample: GSZ, GSM Test conditions: eccentricity 1, speed SPM, stroke 48mm The number of shot 10 thousand times 2 ased on test results in compliance with our standards
