Abstract
The invention discloses a kind of self-lubricating slide rail, the slide rail surface has the plasma spraying self-lubricating coat in use of 20 30 μ m thick.The self-lubricating coat in use of the present invention causes coefficient of friction and wear rate while reducing, with relatively low coefficient of friction, while with the wearability more excellent than Cr coating.Under each load, wear rate reduces by more than 50% than matrix.
Description
Technical field
The present invention relates to extensible member technical field, more particularly to a kind of self-lubricating slide rail and preparation method thereof.
Background technology
Slide rail also known as guide rail, slideway, refer to be fixed on the cabinet of furniture, drawer for furniture or cabinet plate discrepancy activity
Five metals connection member, slide rail are applied to the wooden drawer with furniture such as steel drawers such as cabinet, furniture, official document cabinet, bathroom cabinet and connect
Connect.
Inside the slide rail that naked eyes cannot be seen, it is its bearing arrangement, this part is directly connected to its load-bearing energy
Power.Existing ball guide, roller bearing slide rail, also have silicon wheel slide rail in the market.The former is excluded by the rolling of steel ball, automatically and slides
Dust and foul on rail, so as to ensure the cleaning of slide rail, will not affect its sliding function because foul enters internal.While steel
Pearl can make active force spread to surrounding, it is ensured that drawer stability both horizontally and vertically.Silicon wheel slide rail Long-Time Service,
The chip produced in friction process is in snowflake shape, and its band can also be got up by rolling, does not equally interfere with drawer
Slide freely.
But in actual use, due to abrasion, foreign matter, get rusty, cause slide rail to slide difficult, so as to be difficult to stretch
Contracting, brings very big inconvenience to life.
Content of the invention
It is an object of the invention to a kind of self-lubricating slide rail and preparation method thereof is proposed, enable to slide rail and carry lubrication work(
Can, non-corrosive, slide rail pivoting friction resistance are little.
For reaching this purpose, the present invention is employed the following technical solutions：
A kind of self-lubricating slide rail, the slide rail are formed on the object of the drawer incorporating section for possessing storage drawer, for from institute
State the pull-out of drawer incorporating section or push the drawer, it is characterised in that include：Shifting sledge, inside possess accommodation space, pass through
Evolution face causes the accommodation space and ft connection, and is fixed on the bottom surfaces of the drawer；Rolling element, positioned at the storage
Interior volume, is located on diagonally opposed two jiaos relatively of the shifting sledge respectively；Fixed rack, it include：Fixed part, ball
Body supporting part, connecting portion, the fixed part are fixed on the drawer incorporating section；It is empty that the ball support portion is located at the storage
Between internal, support the rolling element；The connecting portion, one end are connected to the ball support portion, and the other end passes through the evolution
Face leads to the outside of the accommodation space, is connected to the fixed part, and the connecting portion forms 50 with respect to the fixed part
The angle that spends in the range of 70 degree, the slide rail surface have the plasma spraying self-lubricating coat in use of 20-30 μ m thick, the coating
It is prepared via a method which：
(1) by Cr3C2Not reprecipitation is milled on planetary ball mill with NiCr；
(2) Graphene, Ni cladding micron graphite and h-BN is added to continue ball milling at least 10 minutes；
(3), when ball milling stops first 5 minutes, organic binder ball milling is added, obtains suspension；
(4) suspension is carried out mist projection granulating, obtains self-lubricating agglomerated particle；
(5) the self-lubricating agglomerated particle is sprayed in slide rail surface plasma.
Cr of the present invention3C2- NiCr- Graphene is Cr3C2With NiCr with Graphene as a component according to weight
Than (5～3):(2～1):1 mixes.Preferably, the weight ratio is 4:1:1.
The plasma spraying, its electric current are 400-700A, and voltage is 30-70V, main gas argon flow amount 50-140L/min,
Powder feed rate 25-60g/min.Preferably, electric current is 550A, voltage 30V, argon flow amount 50L/min.
Cr3C2There is part adhesive wear based on abrasive wear, also and because fatigue wear causes in-NiCr coating abrasion
Peeling vestige；Add nickel coated modified graphite lubricant coating wear surface self-lubricating coat in use showed increased, this be
In process of friction and wear, graphite is constantly separated out from nickel bag graphite particle, flows, ditch dug with a plow can be played and " fill out under tangential force effect
Flat " effect, thus its wearability can be improved；Nickel coated nanometer h-BN becomes nucleating center, further crystal grain thinning, makes generation
Hard phase CrB4Refinement disperse is in Cr3C2In-NiCr, friction stree makes the h-BN in subsurface stratum be pressed against on surface and forms profit
Synovial membrane.With the increase of h-BN content, lubricating film can be made preferably to be formed, coating abrasion performance is improved.
About 20-30 μm of the composite coating thickness of the present invention, its hardness is significantly improved compared with matrix, more than 500HV0.2.With
When, adding Graphene in composite coating and crystal grain is refined, average grain size drops to 20nm or so
The composite deposite of the present invention causes coefficient of friction and wear rate while reducing, with relatively low coefficient of friction, while
There is the wearability more excellent than Cr coating.Under each load, wear rate reduces by more than 50% than matrix.
Specific embodiment
Technical scheme is further illustrated below by specific embodiment.
Embodiment 1
A kind of self-lubricating slide rail, the slide rail are formed on the object of the drawer incorporating section for possessing storage drawer, for from institute
State the pull-out of drawer incorporating section or push the drawer, it is characterised in that include：Shifting sledge, inside possess accommodation space, pass through
Evolution face causes the accommodation space and ft connection, and is fixed on the bottom surfaces of the drawer；Rolling element, positioned at the storage
Interior volume, is located on diagonally opposed two jiaos relatively of the shifting sledge respectively；Fixed rack, it include：Fixed part, ball
Body supporting part, connecting portion, the fixed part are fixed on the drawer incorporating section；It is empty that the ball support portion is located at the storage
Between internal, support the rolling element；The connecting portion, one end are connected to the ball support portion, and the other end passes through the evolution
Face leads to the outside of the accommodation space, is connected to the fixed part, and the connecting portion forms 50 with respect to the fixed part
The angle of degree, the slide rail surface have the plasma spraying self-lubricating coat in use of 20 μ m thick, and the coating is made by the following method
Standby：
