气弹簧

1.如何实现线形弹簧与氮气弹簧的转换？如何决定氮气弹簧的数量？
在转换的过程中，步是要知道现有的模具所需的压力要求，如果知道完成操作的所需压力，可直接采用相应吨位的氮气弹簧。如果不知道所需总的压力，可通过计算模具中原有线形弹簧所提供的总压力求出。同时，必须要清楚所需压力是初始压力(预压)还是终压力(满冲程)，一旦知道了这些，可得到所需总的压力需求。找出线形弹簧压力的常用的办法是查阅制造商的产品压力图表，通过图表，可知道模具中线形弹簧的规格，颜色，预压和冲程，也可使用测压计来得出弹簧的压力。
2.安装氮气弹簧
在大多数应用中的氮气弹簧可以很容易地安装在同一芯的口袋用来为螺旋弹簧。口袋的深度应该有一个低限度的50%的长度的气弹簧，以较大值为准。在某些应用中可以利用气弹簧的安装选项，如粘贴法兰架，在该基地的气缸盖，及线程体风格。这些选项提供更大的灵活性使用氮气弹簧在现有的模具。
当大小的气弹簧选定的不匹配，弹簧被取代的有简单的可以采取的步骤，然后再安装气弹簧。间隔或袖子可用于在口袋，如果气弹簧小于弹簧，或气体弹簧可能法兰安装在适当的位置。如果现有的口袋是过于肤浅的，它可能是芯更深，如果可能的话，或气体弹簧可能会预装，以满足空间的需求。
后一个关切时，安装气弹簧是利用流体的模具。直接接触某些模具润滑剂，冷却剂和清洁工人可以有害气体弹簧和应予以避免。盾构气体弹簧免受有害液体和提供足够的排水系统，在气弹簧的口袋。
3.如何为氮气弹簧充气?
在进行充气之前，要确保活塞杆充分伸展到顶端，如在没有伸展的情况下进行充气，将导致定位环处于不正确的位置。用T型扳手拧入活塞头顶端的螺孔，待用适当的工具顶压充气阀，使缸体内的气体排尽后，用力向上拉动活塞杆，使得活塞套与定位环顶紧为止。
4.氮气弹簧充气
(1)氮气弹簧充气需要使用专用的充气台或充气装置。对于独立式如果动运输方便可以先充好气、座板系统氮气弹簧侧一定要在工作现场进行充气。
(2)氮气弹簧充气压力在20℃时，标准压力为150(bar)，如果小于130bar充气，用普通氮气瓶即可完成。高于130bar的充气则需用增压装置来完成。
(3)充气前请确认安全挡圈是否安上，并用T型把手使柱塞杆完全伸出，之后调整好所需充气压力值，进行充气。
(4)充气时，气流流经充气阀的速度不要太快，以免充坏充气阀引起漏气，充气完成后用螺塞封好充气口。
注意：充气过程中一定要安全操做，要经过安全培训后方可进行，以免发生不必要的伤害。

1 how to realize the linear spring and nitrogen conversion? How to decide the quantity of nitrogen spring?
During the translation process, the first step is to know the existing mold the desired pressure, if the completion of operations required pressure, directly using the corresponding tonnage nitrogen spring. If you do not know the total pressure, through calculating the die Zhongyuan cable springs with the total pressure calculated. At the same time, must be clear to the required pressure is the initial pressure(pressure)or the final pressure(full stroke), once we know these, can get the required total pressure. Find out the linear spring pressure of the most commonly used method is to consult the manufacturer's product pressure chart, through the chart, can know the mold line shaped spring specifications, colors, preload and stroke, can also be used as a spring pressure gauge.
2 installation of nitrogen spring
In most applications of nitrogen gas spring can be easily installed on the same core pocket used for spiral spring. The pocket depth, there should be a minimum of50% of the length of the gas spring, whichever is greater. In some applications can use the gas spring installation options, such as paste flange frame, at the base of the cylinder cover, and the thread body style. These options provide more flexibility in the existing mold using nitrogen gas spring.
When the size of the gas spring selected do not match, the spring being replaced by simple steps that can be taken, and then install pneumatic spring. Interval or sleeve can be used in the pocket, if the gas spring is smaller than the spring, or a gas spring may be mounted on the flange position. If the existing pocket is too shallow, it may be the core of deeper, if possible, or gas springs may be preloaded, to satisfy the space requirements.
Finally, a concern, the gas spring is installed using the fluid die. Direct exposure to certain die lubricant, coolant and the cleaner can be harmful gas spring and should be avoided. Shield gas spring from harmful liquid and providing adequate drainage system, the gas spring pocket.
3 How to nitrogen inflation?
In inflation before, to ensure that the piston rod is fully extended to the top, as in the case of no extension of the inflatable, will result in an incorrect position of the positioning ring. Using T type wrench is screwed into the piston head at the top of the screw, use appropriate tools top pressure inflating valve, so that the cylinder body of gas drained, forced upward pulling the piston rod, the piston sleeve and a positioning ring tightly.
4 nitrogen gas spring pneumatic
(1) the gas spring pneumatic requires the use of a special charging station or inflatable device. For independent if convenient transportation can be inflated, the seat board system of nitrogen spring side must be in the field of inflatable.
(2) the gas spring pneumatic pressure at 20 ℃, the standard pressure of 150(bar), if less than130bar inflatable, with ordinary nitrogen cylinders can be completed. Higher than that of 130bar are required to complete the air supercharging device.
(3) before the inflatable please confirm safety retainer ring is installed, and T type handle allows the plunger rod extends completely, adjust the desired inflation pressure value, inflation.
(4) when inflated, the air flow passes through the inflation valve speed not too fast, so as not to charge bad inflatable valve caused by leakage, after inflation with plug sealed inflatable mouth.Note: in the process of inflation must be safety operation, to pass safety training before, so as to avoid unnecessary harm.
