Technical field
The present invention relates to a kind of method of leaf springs of car dip-coating paint, belong to auto parts machinery manufacture field.
Background technology
Leaf springs of car is automobile component important in the middle of automobile, and he plays cushioning effect in automobile suspension system, and in automobile manufacturing process, leaf springs of car will can just be manufactured by multiple operations, such as:The operations such as blanking, aligning, drilling, grasswort, quenching, average tempering, shot-peening, assembling, preparatory compression.Spray painting is the operation of phase after mounting, and it mainly plays attractive in appearance and prevents automobile in long-term operation, produces the effect of corrosion.
For a long time, leaf springs of car is all the method using spray painting, exactly hangs on hanger pipeline leaf spring, and being directed at leaf spring with spray gun is sprayed.This method can produce coating cloud, and staff is worked in such circumstances for a long time, harmful, and environment is polluted, not environmentally.Therefore need to improve.
The content of the invention
It is an object of the invention to provide a kind of method of leaf springs of car dip-coating paint, the method is easy to operate, and can largely reduce the pollution to environment, human body is damaged seldom, and be conducive to environmental protection.
Another object of the present invention is to provide the hanger that a kind of method of leaf springs of car dip-coating paint is used, the method that the hanger combines above-mentioned dip-coating paint, so that leaf springs of car dip-coating is painted, it is easy to operate, and can largely reduce the pollution to environment, human body is damaged seldom, and be conducive to environmental protection.
Technical scheme of the invention is:A kind of method of leaf springs of car dip-coating paint, it is characterised in that comprise the following steps:
(1), using dip-coating paint hanger, leaf spring to be painted is hung on the leaf spring hanger of hanger;
(2) the equipment for improving dip-coating paint, by the centrifugal pump in the first fuel tank of original spray painting, changes its motor, its power of motor is increased by three times, major axis size overstriking simultaneously, increases its moment of torsion;
(3) on the basis of former painting case, second painting case is being increased;Two painting cases are coupled together with pipeline;
(5) start centrifugal pump, the paint in the first fuel tank of stirring makes paint stirring uniform, and paint pumped into the second fuel tank, make paint evenly;
(6) by the leaf spring to be painted on hanger, reed is altered together with bolt, certain gap is retained between making reed,
(7) make reed edge-on by dedicated hanging part and at an angle to the horizontal direction(15 ~ 30 degree)
Carry out dipping lacquer application;
(8) it is placed in paint line, in the second painting case of immersion, dip-coating;
(9) taken out after the completion of dip-coating paint;Terminate.
Further, the hanger of dip-coating paint includes, hook, round steel extension bar, leaf spring hanger, and described leaf spring hanger upper end vertically welds together with the round steel extension bar lower end;The round steel extension bar upper end, welds together with described hook lower end, and hook can be hung on leaf spring pipeline.
Further, described leaf spring hanger is made up of band steel connector, spring framework, hanging plate, wherein, band steel connector upper end vertically welds together with described round steel extension bar lower end, band steel connector lower end, the equal spring rack hook of multiple spacing laterally is welded with, on described spring rack hook, equipped with a hanging plate.
Method of the present invention is easy to operate, and can largely reduce the pollution to environment, can remove coating cloud, human body is damaged seldom, and be conducive to environmental protection.

Specific embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail.Fig. 1 is a kind of structural representation of the hanger of the method for leaf springs of car dip-coating paint of the invention.Fig. 2 is the tank equipment schematic diagram of the method.
A kind of method of leaf springs of car dip-coating paint of the invention, comprises the following steps:
Comprise the following steps:
(1) painted using dip-coating and use hanger 6, leaf spring 8 to be painted is hung on the leaf spring hanger 7 of hanger 6;
(2) the equipment for improving dip-coating paint, by the centrifugal pump 1 in the first fuel tank 3 of original spray painting, changes its motor, its power of motor is increased by three times, major axis size overstriking simultaneously, increases its moment of torsion;
(3) on the basis of former painting case 3, second painting case 5 is being increased;Two painting case pipelines 4 are coupled together;
(5) start centrifugal pump, the paint 2 in the first fuel tank 3 of stirring makes paint 2 stir, and paint 2 will be made evenly during paint 2 pumps into the second fuel tank 5;
(6) by the leaf spring 8 to be painted on hanger 6, reed 8 is altered together with bolt, certain gap is retained between making reed,
(7) make reed 8 edge-on by dedicated hanging part and at an angle to the horizontal direction(15 ~ 30 degree)
Carry out dipping lacquer application;
(8) it is placed in paint line, in the second painting case 5 of immersion, dip-coating;
(9) taken out after the completion of dip-coating paint;Terminate.
The hanger that a kind of method of leaf springs of car dip-coating paint is used, it is characterised in that including, hook 9, round steel extension bar, leaf spring hanger, the described upper end of leaf spring hanger 7 vertically welds together with the round steel extension bar lower end;The round steel extension bar upper end, welds together with the described lower end of hook 9, and hook 9 can be hung on leaf spring pipeline.
Further, described leaf spring hanger is made up of band steel connector, spring framework, hanging plate, wherein, band steel connector upper end vertically welds together with described round steel extension bar lower end, band steel connector lower end, the equal spring rack hook of multiple spacing laterally is welded with, on described spring rack hook, equipped with a hanging plate.
Further, the hanging plate is inclined relative to horizontal 30-50 degree, and paint can be made easily to flow down.
Further, described hook 9 is a hook for approximate right angle, easily leaf springs of car can be taken from hanger.
Method of the present invention, it is easy to operate, and the pollution to environment can be largely reduced, and coating cloud can be removed, human body is damaged seldom, and be conducive to environmental protection.
Design of the invention, to those skilled in the art, can derive plurality of replaceable technical scheme with design of the invention, but, every technical scheme derivative under present inventive concept, all within right of the present invention protection domain at the moment.
