Description
Technical field
The present invention relates to a kind of plastic-blasting method technical field, means of defence when the double-colored plastic-spraying of specially a kind of plastic-spraying part.
Background technique
A kind of mode that surface plastic spraying is handled currently as piece surface, is being widely used.But since plastic-spraying operates
The particularity of technique, so the plastic-spraying part used currently on the market is all monochromatic plastic-spraying.During the plastic-spraying of part for
By upper housing and lower case part dimerous, the pipe at upper and lower casing both ends is a siphunculus respectively, individually with it is upper,
The rectangular shell part of lower case is cast.When carrying out plastic-spraying to such part, to guarantee consistency of colour and upper and lower shell
The seam portion of body is handled, so part is the whole plastic-spraying of progress after upper and lower casing assembling.Due to the particularity of workmanship of spraying plastics,
Molding powder is the surface by Electrostatic Absorption in part when plastic-spraying, can not be accomplished while two kinds of particular colors of plastic-spraying.So current nothing
Method realizes the pipe parts at part both ends and the double-colored plastic-spraying of rectangular shell part, and both the pipe parts at both ends were a kind of colors,
Rectangular shell part is another color.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, anti-when providing a kind of double-colored plastic-spraying of plastic-spraying part
Maintaining method can effectively solve the problems in background technique.
To achieve the above object, the present invention proposes: means of defence when a kind of double-colored plastic-spraying of plastic-spraying part, existing not reducing
In the case where thering is plastic-spraying to require with performance, solve the problems, such as to carry out double-colored plastic-spraying in the different surfaces of a part.
As a preferred technical solution of the present invention:
Means of defence when plastic-spraying double-colored the present invention also provides a kind of plastic-spraying part: when a kind of double-colored plastic-spraying of plastic-spraying part
Means of defence, comprising the following steps:
S1): part will first pre-process piece surface before carrying out plastic-spraying (comprising oil removing, derusting, phosphatization, blunt
Change, piece surface antirust ability can be improved after processing, and the surface adhesion force of plastic-spraying layer can be improved).Enter after surface treatment
To step S2；
S2): part preferably uses electrostatic spraying when carrying out molding powder spraying, sprays the pipe parts at part both ends, note first
When meaning control spraying, other parts are not sprayed as far as possible.Step S3 is entered after the completion of spraying；
S3): part after spraying being sent into heater box, closes chamber door, hot setting processing is carried out to the part after spraying, is needed
Heater box is warming up to 185 DEG C, and keeps the temperature 15 minutes.S4 is entered step after the completion of processing；
S4): after completing the plastic-spraying of pipe parts at part both ends, the heat-shrink tube of suitable outer diameter and length is intercepted respectively,
By one end closure, S5 is entered step after the completion of sealing；
S5): by heat-shrink tube opening end cap on completing the pipe parts at the part both ends of plastic-spraying for the first time, until pipe root,
Then pyrocondensation is carried out to heat-shrink tube using 330 DEG C of heat gun, rotating part is paid attention in heating process, so that heat-shrink tube is uniformly received
Contracting.And guarantee heat-shrink tube in pipe parts without slippage.S6 is entered step after the completion of pyrocondensation；
S6): when carrying out the spraying of secondary molding powder to the rectangular shell part of part, only spraying rectangular shell part (it is required that same
S3), step S7 is entered after the completion of plastic-spraying；
S7): hot setting processing treatment process being carried out to the part after plastic-spraying and such as requires same S3, curing process is completed laggard
Enter to step S8；
S8): the heat-shrink tube to shield in the pipe parts at removal part both ends completes the double-colored plastic-spraying of part.
Compared with prior art, the beneficial effects of the present invention are: means of defence when the double-colored plastic-spraying of this plastic-spraying part, not
In the case where reducing existing plastic-spraying requirement and performance, solve the problems, such as to carry out double-colored plastic-spraying in the different surfaces of a part, together
When it is easy to operate, and operate during consumptive material dosage it is less, effectively the different parts of Same Part quickly can be sprayed
Modeling.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
The present invention is the following technical schemes are provided: means of defence when a kind of double-colored plastic-spraying of plastic-spraying part, comprising the following steps:
