Description
Technical field
The invention belongs to Study on painting technology field more particularly to a kind of virtual hanging point coating works of automobile stabilizer bar
Skill.
Background technique
Automobile stabilizer bar, also referred to as stabilizer bar are the important components in automobile chassis suspension system, play maintenance
Vehicle balance prevents from rolling, and adjusts the effect of comfort level；The components are by producing after the forging processing of metal spring steel bar
Then the various shapes for being suitable for automobile difference chassis installation requirements become finished product by heat treatment and ball blast, eventually by table
Preservative treatment is completed in face coating；The coating of stabiliser bar generally uses electrophoretic painting or epoxy powder electrostatic spraying；
The principle of electrostatic powder spraying is that electrostatic generator is released by the electrode needle of spray gun muzzle to the space in workpiece direction
It puts high-pressure electrostatic (cathode), which makes the mixture and surrounding them from the gun slot powder sprayed and compressed air
Air ionization (negatively charged): workpiece is grounded (earthing pole) by carrier chain by hanger, thus between spray gun and workpiece
An electric field is formed, powder reaches working surface under the dual promotion of electric field force and compressed air pressure, makes powder by electrostatic
End attracts in stabiliser bar working surface and forms one layer of uniform coating；
The earrings position of stabiliser bar is connected with mounting, and the thickness of mobile jib is far below in the technical requirements of spraying,
Disadvantage present in traditional spraying method is that 1. need to block progress at stabiliser bar earrings early period, passes through second
Dipping lacquer or plastic-spraying are to reach the different-thickness of paint film, and independent spraying twice, can make the joining place of paint film different-thickness not
It can smooth transition；2. in traditional spraying method, extra powder amount freely falling body can land from high to lower, and under stabiliser bar
End earrings position is easy to appear the accumulation of powder amount, and coating surface is made to generate sagging phenomenon.
Summary of the invention
The present invention proposes a kind of virtual extension of automobile stabilizer bar for the problems in above-mentioned background technique of effective solution
Point coating process, specific technical solution are as follows:
A kind of virtual hanging point coating process of automobile stabilizer bar, including degreasing, washing, table tune, phosphatization and epoxy resin apply
Dress；The epoxy resin coating is first to hang up the stabiliser bar product after phosphatization vertically, in the centre of the earrings of stabiliser bar two sides
The line contact length of position placement plug-in bending-like rectangular section metal hanging point, metal hanging point and stabiliser bar is that entire earrings is long
Then epoxy powder is from top to bottom sprayed the stabiliser bar for setting suspension to 1/5th by a quarter of degree with spray gun, described
The electrostatic high-pressure that spray gun is discharged is between 50kv-60kv, and electrostatic induced current is in 20-30uA on stabiliser bar；
The beneficial effects of the present invention are:
1. the present invention places plug-in bending-like rectangular section metal hanging point at stabiliser bar two sides earrings position, led by it
Electrically, the electrostatic induced current of earrings is influenced, metal hanging point will absorb the powder that should be adsorbed on earrings originally, keep earrings adsorbed
Powder is reduced, to form different film thickness；It is connect 2. the metal hanging point of rectangular section belongs to line with stabiliser bar earrings inner hole
Touching, thus it is very small to the coating masks at stabiliser bar inner hole, it can be effectively prevented from secondary coating, primary dress of completing applies；3.
Absorption by metal hanging point to powder at earrings can be avoided because powder amount accumulates upper sagging, and uniform outer appearance improves anti-corrosive properties
Can, reach salt-fog resistant time 480 hours or more.
Detailed description of the invention
Fig. 1 is the virtual hanging point mounting means schematic diagram of stabiliser bar.
1 is the virtual hanging point in rectangular section, and 2 be Automotive Stabilizer Bar；
Specific embodiment
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawing with embodiment to this
Invention is described in further detail.
Technique of the invention include two ear molding of fracture-- heating-it is integrally formed-quenching-tempering-correction-throwing
The work steps such as ball-coating, and coating work step includes degreasing, washing, table tune, phosphatization and epoxy resin coating, the present invention is to existing
The improvement of coating process " epoxy resin coating " work step, it is improved specifically comprises the processes of:
The stabiliser bar product after phosphatization is hung up vertically first, places plug-in bending-like at the earrings position of stabiliser bar two sides
Then epoxy powder is from top to bottom sprayed the stabiliser bar for setting suspension, the spray gun institute by rectangular section metal hanging point with spray gun
The electrostatic high-pressure of release is between 50kv-60kv, and electrostatic induced current is in 20-30uA on stabiliser bar.
One embodiment is provided below:
It is 3d space stabiliser bar of the 60Si2MnA diameter between 14mm to 32mm that example of the invention, which is directed to material,
Product.Following technique is carried out after product after ball blast is carried out degreasing, washing, table tune, phosphatization:
(1) stabiliser bar is hung on chain vertically；
(2) metal hanging point, the line contact length of metal hanging point are placed in the middle position at the earrings position of stabiliser bar two sides
For earrings length a quarter to 1/5th；
(3) spray gun is adjusted, the electrostatic potential of spray gun is adjusted between 50kv-60kv, spray gun speed is in 550-600mm/s
Between；
(4) adjustment vulcanization air pressure: 0.01-0.05Mpa；
(4) chain starts, chain chain speed: 46-47 revs/min；
(5) Burners Positions are adjusted, control on stabiliser bar that electrostatic potential is between 20-30uA, spary stabiliser bar from top to bottom.
By detection, the film thickness of two earrings of stabiliser bar reaches the technical requirements of 30~60um, product salt-fog resistant time
Reach 480 hours or more.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as the protection scope of invention.
