Description
Technical field
The present invention relates to automobile plastic component surface treatment technology, and especially and a kind of high-intensity high-tenacity nickel metal covers work
Fill preparation method.
Background technology
With the increasingly lifting of people's automotive needs, the innovation and lifting to the technique of auto parts machinery result in.Masking spray
Paint or chromatography lacquer spraying technique is arisen at the historic moment, this masking spray painting requires more strictly to spray beyond the chromatography of traditional arts and crafts
Apply, there have been masking frock.Frock：Technological equipment, it is a kind of correction work in order to meet the production of certain product and make
Tool, it is desirable to can not there is paint to fly out or spray the problem of not in place when covering frock spray painting, increase manpower erasing otherwise occurs
Fly paint problem, or cause bad because show-through, and then reduce qualification rate, while blank to be painted then needs because there is problem on deformation
Also to play the role of to product during die pressing product under frock orthopedic.Conventional masking frock covers work in painting process
The increase of surface lacquer thickness is filled, results in the need for taking out paint by cleaning, and adds cleaning frequency, to the plastics of deformation
Product can not play good bridging effect, and utilization rate is relatively low, it is larger cover error in addition, it is impossible to accurately play the work of masking
With.
The content of the invention
It is an object of the invention to overcome above-mentioned prior art to need frequent clean frock, nickel coating thickness does not reach requirement,
The blank of spray painting is because having deformation, toughness chipping or cracking during frock frequently use, frock and product mismatch error
Larger, screening effect is poor, and use range is limited, the problems such as short life.Following technical scheme is provided：
A kind of high-intensity high-tenacity nickel metal covers frock preparation method, comprises the following steps：

4）The demoulding：Heating and melting peels off plastic cement products core rod from nickel coating；
5）Blasting treatment：Blasting treatment is carried out for the nickel coating outer surface for taking off plastic cement products；
6）Slightly repair：Remove the sandblasting overlap and sandblasting buildup around nickel coating outer surface, using a length of 130mm, a diameter of 1mm's
Multi-face tooth thread saw blade, sand side, and the surplus sand of reserved spraying area edge 0.2mm width are cut according to plastic cement products size
Side；
7）Refine：Using the miniature half smooth file knife of double cut to step 6）The reserved spraying area edge 0.2mm width of nickel coating in process
Surplus carry out refine, polish smooth, remove flash removed；
8）Assembling：A diameter of 10mm round steel piece is welded into rectangularity, circle or plastics according to plastic product non-spraying area to produce
The framework of the actual non-spraying area shape of product, the nickel coating after refine is buckled in product non-spraying area, after completing contraposition, uses tin
Weld-bonding round steel piece and nickel coating are integrated, that is, obtain nickel metal masking frock product；
9）Examine：The sample after plastic product is installed to nickel metal masking frock product and carries out examination spray, detects whether oil be present
Paint is show-through or other overlaps also be present from round steel piece.
Preferably, the blasting treatment uses the sand-blasting machine with separating screen device to carry out blasting treatment, spray to spraying position
Material is sanded and selects 24# white fused alumina sand, blasting pressure is 0.2~0.6MPa, and sandblasting is 100~300mm apart from area to be sprayed, pressure
Direction and matrix surface out of plumb, matrix surface is embedded in prevent sand grains；After sandblasting, it will be adhered to the compressed air of clean dried
The broken sand and floating ash of workpiece surface are blown off.
Preferably, the step 4）The temperature control of middle heating and melting is at 120~140 DEG C.
