Description
Technical field
The present invention relates to the production and processing method technical fields of splined hub workpiece, and in particular to a kind of Buddhist nun for splined hub
Imperial coated technique.
Background technique
Splined hub nylon-coating is widely used in truck drive shaft field, applies Buddhist nun on the splined hub surface of transmission shaft
On the one hand dragon avoids directly contacting between steel part when splined shaft cooperates with splined hub, plays the wear-resisting effect of damping, another
Coating nylon can improve the cooperation precision with oil sealing on the outside of aspect splined hub, while play antirust function, and before nylon-coating
Manage extremely critical, the success or failure of pre-treatment are related to nylon adhesion effect.
Splined hub is transported to nylon-coating workshop and applies one layer to its internal spline and outer surface after machine shop processing
Nylon coating inevitably attaches a large amount of greasy dirts and a little iron is cut in splined hub machining process, in transport process,
The pollutants such as dust are unavoidably attached again, and traditional approach uses gasoline cleaning method, and worker scrubs part with brush one by one
Completely, it then will accelerate to dry up under placing part fan, take time and effort, gasoline needs to carry out whole pond update daily, and part yet needs
It cleans, dry or dries, very complicated and efficiency is very low.In actual production, using gasoline cleaning, there are many deficiencies
Place, on the one hand, this method is not effective to the biggish part of greasy residues, and after especially putty mixing attaches, scrub is not only
There is no effect, the more can wash the more dirty instead, hidden danger of quality is very big, part uneven color after coating, after individual part applies nylon
Adhesive force is very poor, and nylon is easy to remove from sliding sleeve；On the other hand, which needs worker to have extremely strong responsibility
The heart, every part are intended to scrub one by one, dry, cumbersome, large labor intensity, and in attachment force inspecting or following process
It in assembling process, or often will appear nylon obscission, returned by the gross to guarantee that quality can only apply nylon part to the batch
Work causes greatly to produce waste, and also often occurs individual part nylon in Market Feedback and fall off the quality accident of failure；Vapour
Oil volatilization also causes very big influence to worker and processing environment, finds that the nylon poor adhesive force overwhelming majority is former by multi-party analysis
It is because being that splined hub is handled before applying nylon unqualified, so the nylon-coating process for needing one kind new solves the problems, such as this.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of techniques of splined hub nylon-coating, including Work inspection device, throwing
Ball processing, primer dipping and coating, coating nylon, reach expected results and substantially increase workpiece adhesive force detection it is qualified
Rate has eliminated the mode of gasoline cleaning, has improved processing environment and the labor intensity of worker.
The present invention provides a kind of nylon-coating process for splined hub, including following step in order to solve the above problem
It is rapid:
Step 1: inside and outside integrity checking is carried out to mach workpiece, workpiece is packed into material frame, in batches falls a material frame workpiece
Enter in shot-blast cleaning machine and carry out Shot Blasting 5-8 minutes, the steel sand granularity in shot-blast cleaning machine is 1.5-1.8 millimeters；
Step 2: the workpiece surface after Shot Blasting is removed using air gun and remains steel sand；
Step 3: the part that workpiece is needed to apply is immersed in priming paint 1-2 seconds, is placed on workbench and is dried, until priming paint does not drip
It falls；
Step 4: falling the priming paint of workpiece bottom in cotton supernatant, and workpiece is sent into heating furnace and is heated, and heating in-furnace temperature is
290-320 DEG C, until workpiece surface temperature is 270-300 DEG C, and workpiece surface is in dark-brown；
Step 5: take out workpiece, with fixture clamp workpiece do not need coating one end and keep workpiece vertical, workpiece is needed to apply
The 1/3-1/2 of nylon section immerses in nylon coating fluidized bed 3-5 seconds, then needs to apply nylon section for workpiece and is totally immersed into
Nylon coating fluidized bed 15-17 seconds；
Step 6: being upside down in naturally dry in the movements and postures of actors for the workpiece after dip-coating, checks and applies when workpiece surface temperature is lower than 60 DEG C
Whether layer part has impurity, protrusion or collides with, and then measures nylon thickness.
Further, check that underproof workpiece uses high pressure water after 420-460 DEG C of high-temperature heating in the step 6
Rifle removes priming paint and nylon coating, then carries out step 1 and processes to step 6.
Further, the steel sand in the shot-blast cleaning machine of the step 1 is diamond shape.
Further, Number of Jobs is 100-150 part in the step 1 material frame.
Further, the priming paint is 7P-0200 priming paint.
Further, the shot-blast cleaning machine is apron type airless shot blasting machine.
Beneficial effect
1, the solution of the present invention is used for the surface nylon-coating of splined hub, and the workpiece after machining is detected no inside and outside defect
Afterwards, it is framed up and puts into apron type airless shot blasting machine progress Shot Blasting, the steel sand in shot-blast cleaning machine is diamond shape, and granularity is
1.5-1.8 millimeters, Shot Blasting can effectively remove the burs such as greasy dirt, iron filings and dust of workpiece surface adherency, and 5-8 minutes
Cleaning while multiple workpiece, relatively previous artificial and effect high using cleaning efficiency for gasoline cleaning can be completed in batches
It is good, while reducing a large amount of gasoline and expending, save very big expense, improve workshop processing environment, and it is opposite with
Toward the artificial mode for clearing up workpiece one by one, greatly reduce the labor intensity of worker, need to only be used after impeller blasting air gun or
Other toolings remove the possible remaining steel sand of workpiece surface, and two steps replace previous multiple steps, when reducing mass production
Between；
2, being heated to workpiece surface temperature in heating furnace after workpiece leaching priming paint dries is 270-300 DEG C, and workpiece surface is deep at this time
Brown can be judged by color board, first need the part 1/3-1/2 of the part applied to be submerged initially in nylon workpiece when applying nylon
Coating fluidized bed 3-5 seconds, then coated portion is needed integrally to immerse nylon coating fluidized bed workpiece, entire coating process exists
10-20 seconds, since nylon material takes difference, shake 3-4 times up and down is needed when applying German nylon powder, when coating A Kema nylon powder
When need shake 5-7 time up and down so that nylon-coating is uniform, guarantee to apply effect；Product warp underproof for coating effect
Primer surface and nylon coating are removed with giant after 420-460 DEG C of high-temperature heating, re-starts processing, secondary operation is still not
It is done over again when qualified to machining processes before.
