In covering truewood wood skin, truewood wood skin is protected using the protective paint layer that finishing coat is formed, the abrasion of truewood wood skin is reduced, extends truewood
The service life of wood skin.
Apparatus for baking is provided, apparatus for baking is used to dry the finishing coat after the spraying of topcoating device, so that topcoating cures adhere to
On semi-finished product.In the present embodiment, the baking temperature of the apparatus for baking is 10-20 DEG C lower than the hot pressing temperature of hot pressing die, when
At 10 DEG C lower than the hot pressing temperature of hot pressing die of the baking temperature of apparatus for baking or less, easily make automobile decoration shell second melting
And cause product bad；When 20 DEG C lower than the hot pressing temperature of hot pressing die of the baking temperature of apparatus for baking or more, it will cause
Topcoating cures inefficiency will be greatly reduced the production efficiency of product.
It further includes following steps that the truewood, which generates technique:
Glue stations is provided, glue stations is used to coat UV glue to hot pressing die treated semi-finished product, and UV glue is for hiding
Lid truewood wood skin.
In actual use, transparent outer cover is made in plastic suction forming apparatus plastic uptake, the UV provided under vacuum conditions with glue stations
Glue is coated on hyaline test on the outside of semi-finished product, carries out filling PUR processing to semi-finished product using glue stations, glue stations is to gluing
Semi-finished product after device spraying UV glue carry out filling transparent adhesive tape processing, and transparent adhesive tape is used to cover the UV glue and truewood wood skin of semi-finished product,
UV glue and truewood wood skin are consolidated using transparent adhesive tape and are attached on semi-finished product, prevents UV glue, truewood wood skin by extraneous object
It touches and damages；The heating temperature of glue stations is lower than the heating temperature of hot pressing die, prevents glue stations from filling PUR processing
Separate the automobile decoration shell to have fit together and truewood wood skin.
Numerically-controlled machine tool is for milling glue stations treated semi-finished product.
It further includes following steps that the truewood, which generates technique:
Burnishing device is provided, burnishing device is provided with the buff of rotation, and buff is used for numerically-controlled machine tool milling
Treated, and semi-finished product are polished, and buff is used to contradict numerically-controlled machine tool the transparent adhesive tape of treated semi-finished product.Utilize throwing
Electro-optical device polishes semi-finished product, so that semi-finished product form the bright face of bloom, to complete the truewood of entire automobile decoration shell
Generate technique.
It further includes following steps that the truewood, which generates technique:
Laser cutting device is provided, laser cutting device is for cutting truewood wood skin, so that the shape and vapour of truewood wood skin
The shape of vehicle Decorative shell is coincide.
Hot pressing die is for the truewood after cutting injection molding machine automobile decoration shell formed after injection molding and laser cutting device
Wood skin hot pressing fits together.
It further includes following steps that the truewood, which generates technique:
Automobile decoration shell surface after injection molding machine injection molding coats clear water, and the truewood wood skin after laser cutting device is cut passes through
It is attached on automobile decoration shell in advance by clear water, it is middle compared to the prior art that truewood wood skin is attached to automobile decoration shell in advance using glue
On, it on the one hand reduces using adverse effect brought by performance of the glue to truewood wood skin, on the other hand auxiliary reduces automobile dress
The manufacturing cost that the truewood of shell generates is adornd, hot pressing die is equipped with the heat for being installed with the truewood wood skin after pre- patch and automobile decoration shell
Press chamber.
Vacuum is provided and attaches device, vacuum attaches the hot pressing chamber of device and hot pressing die, and vacuum attaches device pair
Hot pressing chamber vacuumizes so that the clear water between automobile decoration shell and truewood wood skin is extracted, and clear water is avoided to be trapped in automobile dress
Influence the service performance of finished product between decorations shell and truewood wood skin, hot pressing die is used to attach vacuum device treated automobile
Decorative shell and the hot pressing of truewood wood skin fit together to form semi-finished product.
In the present embodiment, the hot pressing pressure of the hot pressing die is 2.5-3.5MPa, when the hot pressing pressure of hot pressing die is low
When 2.5MPa, truewood wood skin cannot be firmly pressed together on automobile decoration shell, and the two is easily separated from each other and opposite move occurs
It is dynamic；When the hot pressing pressure of hot pressing die is higher than 3.5MPa, it is easy to cause product bad automobile decoration shell compressive strain；Hot pressing
The hot pressing temperature of mold is 130-180 DEG C, and when the hot pressing temperature of hot pressing die is lower than 130 DEG C, automobile decoration shell will not be melted,
Truewood wood skin is difficult to be adhered on automobile decoration shell；When the hot pressing temperature of hot pressing die is higher than 180 DEG C, automobile decoration shell can melt
Change deformation, causes product bad；A length of 100-130s when the hot pressing of hot pressing die, when the hot pressing duration of hot pressing die is lower than 100s
When, the part of truewood wood skin cannot be firmly pressed together on automobile decoration shell；When the hot pressing duration of hot pressing die is higher than
When 130s, truewood wood skin can be reduced with the hot pressing of automobile decoration shell and be bonded efficiency.
The hot pressing die semi-finished product to be formed that fit together to automobile decoration shell and the hot pressing of truewood wood skin carry out pressure maintaining
Processing, the dwell pressure of hot pressing die are 2.5-3.5MPa, and the pressure maintaining temperature of hot pressing die is 25-35 DEG C, the guarantor of hot pressing die
A length of 100-130s when pressure, clout of the numerically-controlled machine tool for milling hot pressing die pressure maintaining treated semi-finished product.Pass through hot-die
The pressure maintaining of tool is handled, it is ensured that internal stress slow release of the automobile decoration shell with truewood wood skin when hot pressing is bonded avoids hot pressing
The too fast cooling of semi-finished product after fitting and lead to internal residual stresses, processing when promoting subsequent numerically-controlled machine tool milling semi-finished product is good
Rate.
The temperature of the glue stations is 80-85 DEG C, prevents glue stations temperature excessively high and destroys automobile decoration shell and true
Attachment force between wood skin avoids automobile decoration shell and truewood wood skin when melten gel cladding processing from disengaging；Transparent adhesive tape for glue laminated
Power is 5-8MPa, and when transparent adhesive tape is when being lower than 5MPa for glue laminated power, transparent adhesive tape cannot fully coat semi-finished product, be easy to cause half
Finished product manufacture is bad；When transparent adhesive tape is when being higher than 8MPa for glue laminated power, when transparent adhesive tape injects, truewood wood skin is easily because by transparent
Glue injection impact force and generate fold, cause product manufacturing bad.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
