Abstract
The invention discloses a kind of damper, including：Piston,Piston rod,Rebound valve,Compression valve,Cylinder body,Cylinder seat,Spring and coating material,When wherein by downward pressure,Piston rod is under pressure to be pushed with piston to cylinder body,Spring in cylinder body is compressed and the gas pressure of bottom chamber increases,Gas pushes compression valve open and carries out throttling process,And spring also has certain damping action in throttling process,Slow down so that pushing,When by upward pressure,Piston rod is under pressure band piston to cylinder body progress upward pressure,Now upper chamber is compressed,So that spring is stretched and the gas pressure in upper chamber becomes big,Rebound valve is open under the effect of the pressure,In chamber under throttling process and the double action of spring,Damping action is carried out to piston and piston rod,The present invention adds spring in telescopic shock absorber and strengthens damping effect,And coating is added in cylinder body,Strengthen service life.
Description
Technical field
The present invention relates to field of machinery automation, particularly a kind of damper.
Background technology
Machinery manufacturing industry occupies highly important status in whole national economy, and is usually used in wherein mechanical use
Damper, but oil plant is added in common telescopic shock absorber, and there is no certain protection in cylinder interior, a large amount of oil plants make
With not only increasing cost, and it is also more limited without the general service life of damper of inboard wall of cylinder block protection, not only exist
Make troubles, can not be used for multiple times for a long time in work.And only entered in using damper by throttling action
Row damping is easy to make cylinder body sustain damage.
The content of the invention
It is an object of the invention to provide a kind of damper protected cylinder body and used without oil plant.
The invention provides a kind of damper, including：Piston, piston rod, rebound valve, compression valve, cylinder body, cylinder seat, spring
And coating material, wherein during by downward pressure, the piston rod band piston that is under pressure pushes to cylinder body, in cylinder body
Spring is compressed and the gas pressure of bottom chamber increases, and gas pushes compression valve open and carries out throttling process, and spring is throttling
During also have certain damping action so that push and slow down, when by upward pressure, piston rod be under pressure band piston
Upward pressure is carried out to cylinder body, now upper chamber is compressed so that spring is stretched and the gas pressure in upper chamber becomes big, stretches
Open valve to be open under the effect of the pressure, in chamber under throttling process and the double action of spring, to piston and piston rod
Carry out damping action.
The piston, is connected with piston rod, by being driven by piston rod so as to be compressed effect to cylinder interior.
The piston rod, is connected with piston, by being acted on the piston of connection to reach decompression after being under pressure
The effect of work.
The rebound valve, upper chamber is pushed open by gas compression, rebound valve by compressed gas when being acted on by upward pressure, complete
Into throttling action, rebound valve opening direction is to lower chambers direction.
The compression valve, lower chambers are pushed open by gas compression, compression valve by compressed gas when being acted on by downward pressure, complete
Into throttling action, compression valve opening direction is to upper chamber direction.
The cylinder body, by being connected with cylinder seat, and piston rod forms closed system, and wherein cylinder interior is full of nitrogen, and
Inboard wall of cylinder block scribbles coating.
The cylinder seat, by being connected with cylinder body, and piston rod forms closed system, and ensureing the gas of cylinder interior will not let out
Dew.
The spring, by being connected with piston rod, strengthen damping action when damper works.
The coating, by being applied on the inside of the cylinder body, reduce the abrasion of cylinder body.
It is an advantage of the invention that：
Spring is added in telescopic shock absorber and strengthens damping effect, coating is added in cylinder body, strengthens service life, and in cylinder body
Interior addition nitrogen filling.
