Description
Technical field
The utility model relates to the manufacturing equipment of gas-liquid vibration absorber, especially a kind of gas-liquid vibration absorber charging-sealing device.
Background technology
Existing gas-liquid vibration absorber adopts seals, the gas filling technology method has two kinds usually, first kind, adopts three flange of hydraulic press to seal, and then inflates on inflator; Second kind, after spinning roller spinning flange seals, inflation again.
The concrete technology that adopts three flange of hydraulic press to seal is as follows: at first, utilizing for the first time, Closing in die carries out workpiece to seal the first time, hydraulic press moves downward and drives the closing in die workpiece position of closing up is covered, hydraulic press continues to move downward, oil sealing pressure head contact seal, the compression spring is compressed, and the die that closes up at last becomes 30 ° with the harvest of workpiece oral area with vertical axis; Then, utilization Closing in die is for the second time carried out workpiece to seal the second time, makes the harvest of workpiece oral area become 60 ° with vertical axis, at last, utilize for the third time that Closing in die seals workpiece for the third time, make the harvest of workpiece oral area become 90 ° with vertical axis, flange seals end.This kind processing method needs three flange of hydraulic press to seal, and it is not very firm that flange position and oil sealing are fitted, and process time is long, and labor strength is big, and production efficiency is low.
The technology that spinning roller spinning flange seals is as follows: rotation press closing as shown in Figure 1, at first, workpiece is positioned on positioning seat 24 and the roller 22, sealing device drive positioning seat and workpiece up, till oil sealing pressure head 21 is pushed down oil sealing; Then, spinning machine drives positioning seat 24 and workpiece rotation, simultaneously, spinning roller 23 radial feeds utilize the surge drum oral area flanging of head R with rotation, make it become 90 ° with vertical axis, after flanging put in place, rotation stopped, and it is descending that equipment drives workpiece, at this moment take off workpiece, whole rotation press closing process finishes.The shortcoming that rotation press closing exists is: because the radial feed of spinning roller 23, the rubber that exists the oil sealing end face to seal is pushed away the risk of closure part, and the attenuation of closure part metal, intensity difference.
And the product after the above closing in, need inflate gas-liquid vibration absorber, product orientation after sealing is loaded onto at inflator, and descending along with equipment drives inflator and load row, product is pierced into the frock endoporus, when surge drum flange position touched the frock inner face, equipment stopped descending, at this moment the sharp pawl on the aerating device, thrust between oil sealing and the connecting rod, make it the gap occur; The gap that high pressure nitrogen occurs between oil sealing and connecting rod enters in the damper body, reach the blowing pressure after, inflation finishes.
Two kinds of above-mentioned technologies are sealed and are inflated separately and carry out, and need two equipment; In the gas replenishment process, the risk that exists oil sealing to be damaged; During inflation, gas can enter the working cylinder epicoele through the gap between connecting rod and the guide holder.
