Description
Technical field
This utility model relates to a kind of nitrogen spring, uses the nitrogen spring of TD process particularly to a kind of piston pole face.
Background technology
Nitrogen spring is a kind of novel elastic assembly with high pressure nitrogen as working media, and its volume is little, elastic force big, stroke
Long, stable working, manufactures precision, length in service life (1,000,000 times), and spring curve is mild, and need not pretension etc., it
There is the work that the common elastic assemblies such as metal spring, rubber and air cushion have been difficult to.
Produce in automobile component mould, use nitrogen spring the most in a large number.Such nitrogen spring existing exists in the majority
Defect.As: be easily damaged, can not recycling, use cost is high.Piston rod is weighed ability.
Utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, it is provided that a kind of piston pole face uses
The nitrogen spring that TD processes.
To achieve these goals, the measure that this utility model is taked:
A kind of piston pole face uses the nitrogen spring that TD processes, including piston rod and nitrogen spring outer sleeve, nitrogen spring
Being provided with nitrogen storage chamber, the upper opening of nitrogen spring outer sleeve in outer sleeve, the outer bottom of nitrogen spring outer sleeve is arranged
Have mounting ring, offer in the diapire of described nitrogen spring outer sleeve with nitrogen deposit chamber L-type inflation through hole, L-type
The outside of inflation through hole has been threaded connection sealing plug, is arranged with fairlead in nitrogen spring outer sleeve, and piston rod is sheathed
In fairlead, piston rod one end stretch as in nitrogen spring outer sleeve, the other end reach outside nitrogen spring outer sleeve, piston
The inner of bar is arranged with support set, the outer cover of support set is provided with sealing ring, sealing ring be close to nitrogen spring outer sleeve
On inwall；The outer surface of described piston rod uses TD process, and the surface of piston rod forms a carburization zone.
The outer end of described piston rod is arranged with sealing lid, seals between lid and nitrogen spring outer sleeve by screw thread or card
Button connects；
