The process control steps are as follows:
processing the surface of the machined blank: performing casting shot blasting treatment on the machined blank;
spraying base powder: performing base powder spraying on the hub subjected to shot blasting treatment, wherein the quality of the base powder needs to be paid attention to before the base powder spraying, the uniform powder spraying and qualified thickness need to be paid attention to in the base powder spraying process, and the bad defects such as powder bags, powder pits and the like are controlled;
and (4) sticking back surface type following protection: pasting aluminum foil on the back, wherein lettering marks X and M in the flange surface lightening pit are opposite to two windows for chromatography, the back of the chromatography window is completely covered, the method is compacted along the edge of the window, the aluminum foil is firmly pasted on the front side in a checking way, the aluminum foil is not loosened by pressing with fingers, defects in the surface chromatography window are checked and polished, cleaning cloth (cleaned by purified water) is used for wiping the defects, and aluminum foil paper of a back cavity is pasted according to the sequence of supplied materials;
grinding off line of powder: polishing the appearance particles inside and outside the chromatography window and wiping the particles clean by a wetting cloth;
spraying red paint: the color sleeving tool is protected in place; polishing a chromatic window: online polishing and division: polishing a red spraying window on line, checking whether an aluminum foil is adhered or not by one person, polishing the chromatography window by one person, blowing dust and wiping dust by one person, and performing recheck by one person to remove dust by using a wetting cloth and recheck the appearance again; during paint spraying, manually repairing the window part in a primer spraying room, and paying attention to control the defects of leakage, sagging and the like; starting an automatic spray gun in a colored paint spraying room to spray, ensuring uniformity according to process parameters, and not starting a side gun; spraying red paint by a special hand, and checking the included angle of the window and the inclined plane of the window against bottom leakage by spraying the red paint;
taking protection: taking a front-side color register tool (a transfer vehicle for storage) at an automatic paint line off-line position;
and (3) offline polishing and sorting of red paint: sorting and reworking the same-color particles and different-color particles with the appearance of more than 1mm and without sagging and leaking in the inspection window; polishing and flattening the red paint left by the tool and wiping the red paint by using a wetted cloth;
protection is pasted along with the type on the front: the quality of the non-processed surface on the front side is comprehensively checked, and aluminum foils are pasted on the front side and the back side after the quality is qualified (note: the back side is firm and does not need to be pasted again for replacement); the part of the front side pasted with the aluminum foil takes the valve hole as a reference, clockwise windows are pasted with protection, and the front side pasted with the aluminum foil is compacted and pressed;
black paint spraying: online polishing is controlled according to a normal product production mode, wherein one person is responsible for the side face of the spoke in a large inclined plane window and a central hole; one person is responsible for soot blowing; one person rechecks and uses the wetting cloth again to remove dust, recheck the appearance and paste the aluminum foil to compact the situation; spraying black paint in a transparent paint room, and fully covering the rim with the black paint;

Turning a machine and adding finish turning: paying attention to damage and paint collapse to ensure that the paint does not jump when the cutter is taken out, adjusting the first rotation speed of the finish turning procedure to 900-1200r/min (the rotation speed of a normal product is 900-1400 r/min), and adjusting the feeding to 0.3-0.5mm/r (the rotation speed of the normal product is 0.2-0.5 mm/r).
Finish turning of the rotating piece: color mixing inspection of a color register window, polishing of black particles of a non-processing surface and cleaning;
finish turning, offline repair and rechecking: secondary powder spraying, reworking (iron cutter process), polishing and repairing, paint removing and scrapping.
Reworking the reworked product: the quality of the red window is solved, the polished window is directly reworked and polished by a milling cutter to be milled for 1.2-1.5mm, and then red paint is sprayed; the black color has quality problem, and the sticker is directly milled to be 1mm wide by spraying black paint; slightly processing the tool to prevent paint pollution, and directly milling a 1mm turning finish turning milling cutter by a milling cutter; only a pinhole in a knife processing and slag inclusion scrapping are needed to be processed for the reworked product; the repaired product is only machined once, and the milling cutter can not be directly rotated for about 1mm to remove paint due to the red window problem or the black non-machined surface problem;
and (3) reworking red paint production: reworking and polishing to polish the red appearance; milling the workpiece with a milling cutter to a width of about 1.5mm (note: the corner is smoothed by a straight mill); the production plan is arranged, and is cleaned in a centralized way after pretreatment, and a transfer area is transferred to a chromatography area after being independently stacked; and (4) producing according to a normal initial powder wheel production process (note that the step of polishing the drain bottom needs manual repair and then automatic spraying).
The color register spraying process flow is improved:
combined tool protection → aluminum foil is pasted on the back cavity of the window → color paint spraying for the first time → aluminum foil is pasted on the front surface and the back cavity of the window → color paint spraying for the second time → adhesive removal
The matching performance of the paint is improved:
the base powder used is JW-A1701C base powder (sky), the first colored paint is BK-01-DY black paint (Danyang modern), G1311-4010 orange-DY (Danyang modern), and the transparent powder is PCC10103 transparent powder.
Manually spraying an included angle of a window and spraying orange color by a machine during color matching; and wiping the stained glue by using a residual glue remover.
The paint is matched to ensure that the normal products of the wheel hub are not subjected to off-line paint collapse.
Protection frock and shielding frock improve:
the protection tool adopts a perfluororubber tool, the shielding tool adopts an aluminum foil, and the color register window part is shielded by large and small paper-coated aluminum foils.
The diaphragm pump spray gun and the pressure reducing valve are used for spraying, so that stable spraying pressure is guaranteed, the weight of the spray gun is reduced, the labor intensity of workers is reduced, and the product quality is improved.
The second embodiment:
the embodiment is a traditional chromatography spraying process, and the process flow is as follows:
painting → window tooling protection → painting of painting No. two.
The front and the window are not protected.
The paint is matched with JW-A1701C base powder (skyscraper), SP110 DK 2A1 black paint (Nippon), G1311-4010 orange red (Aishide) and PCC10103 transparent powder.
The paint matching is adopted, so that the off-line paint collapse of normal products is serious.
The color register window is sprayed by using a kettle gun for 0.7 hour per batch, and when a worker works for a long time, the worker presses a needle valve with a finger to cause the hand to be sour, so that the spraying quality (included angle leakage) is influenced.
Example three:
the embodiment is a preliminary improvement of a spraying process, and the process flow is as follows:
protection of combined tooling → kraft paper pasted on the back cavity of the window → painting of the first colored paint → kraft paper pasted on the front surface and the back cavity of the window → painting of the second colored paint.
The protection tool is adopted: 202 stainless steel + fluororubber combined tooling, the shielding tooling adopts aluminium foil, and the chromatography window part is shielded by large and small (different thicknesses) laminated paper aluminium foil.
The paint is matched with JW-A1701C base powder (skyscraper), BK-01-DY black paint (Danyang modern), G1311-4010 orange-DQ (bridge chemical industry) and PCC10103 transparent powder.
The off-line paint collapse of normal products is slight due to the adoption of the paint matching.
