The method comprises the following processing steps of: (1) winding and coating: making the glass fibre reinforced plastics into a strip shape, and then winding to the surface of the metal shell layer by layer after the surface is coated with rubber; (2) solidifying the glass fibre reinforced plastics; (3) cutting the surface of the glass fibre reinforced plastics; (4) and finishing. The strip-shaped glass fibre reinforced plastics are utilized to coat the metal shell, the processing procedure is reasonable,and the glass fibre reinforced plastics coated outside the metal shell has small deformation and are not easy to generate the phenomena of peeling, scaling off, expanding and the like; and the end surface of the processed shell has good planeness.
Description
Technical field
The present invention relates to the method for metal working of coated with glass fibre reinforced plastics, specifically is a kind of processing method of high-precision thin-wall metal shell of coated with glass fibre reinforced plastics.
Background technology
Fiberglass is coated on the metal surface can play effect heat insulation, adiabatic, antiradiation, has that good high and low temperature is heat insulation, adiabatic, the antiradiation characteristic, and adiabatic temperature can reach more than 1000 ℃.In mechanical industry, the metal shell of coated with glass fibre reinforced plastics is used less, aspect aviation, navigation, does not yet use, and only space flight aspect at home is applied at present.And domestic processing method to metal shell surface coated with glass fibre reinforced plastics yet is in the stage of fumbling; The processing method that adopts at present is that fiberglass is made into the cloth shape; In layer be wound into the metal shell surface behind the surface coating; But have adhesion between fiberglass and metal surface, problem that adhesive force is little after coating, adding man-hour can peeling, fall phenomenons such as slag, expansion; And guarantee that at present two kinds of materials of fiberglass and metal form the method that flatness adopted on plane and also rest on car, mill the back and guarantee that by the pincers worker manual grinding fiberglass and two kinds of materials of metal form the flatness on plane, the flatness on two kinds of materials formation of processing back fiberglass and metal plane is relatively poor; Can't satisfy behind the coated with glass fibre reinforced plastics of high-precision thin-wall metal shell surface non-scale in the processing, do not fall slag and car, mill the requirements such as higher level degree that to satisfy two kinds of materials compositions of fiberglass and metal plane after the processing.
Summary of the invention
The present invention exists for the metal shell that solves the surface that processes with existing method and be coated with fiberglass: fiberglass and intermetallic adhesion, adhesive force are little; Be prone to peeling in the processing, fall slag, expansion; Two kinds of materials of fiberglass and metal are formed the problems such as flatness difference on plane, and a kind of processing method of high-precision thin-wall metal shell of coated with glass fibre reinforced plastics is provided.
The present invention adopts following technical scheme to realize: the processing method of the high-precision thin-wall metal shell of coated with glass fibre reinforced plastics, and procedure of processing is following:
1), twine encapsulation steps, fiberglass is made into band shape, successively be wound in the metal shell surface behind the surface coating;
2), the fiberglass curing schedule, at first under 80 ℃, solidify 5～6h; Again under 60 ℃, solidify 4～6h;
3), glass fiber reinforced plastic surface cutting step, with diamond cutter glass-cutting steel surface, and the cutting direction of guarantee fund's diamond cutter is consistent with the winding direction of ribbon glass steel, cutting parameter is cutting speed v=15～20m/s, cutting depth a
p=0.2～0.5mm, amount of feeding f=0.05～0.1mm/rev;
4), the polishing procedure of processing, the metal covering and the glass steel surface of polishing turning housing end face are at first with the glass steel surface of diamond cutter processing housing end face, with the metal covering of carbide alloy coating cutter processing housing end face; Then with the glass steel surface and the metal covering of diamond cutter half finish turning housing end face; The value that adopts signing method to measure glass steel surface at last to exceed metal covering is (because it is different with metal to add density, percentage elongation, the distortion of fiberglass in man-hour; After turning processing; Glass steel surface can exceed about 0.1mm than metal covering is general); According to measured value the glass steel surface of housing end face is carried out polishing processing, reach 0.015mm until the flatness of housing end face.
Compared with prior art, the present invention adopts banded coating to substitute the cloth shape and coats the winding coating of realization fiberglass on the metal shell surface, can effectively improve fiberglass and intermetallic adhesion, adhesive force; And after coating, under dual-temperature (80 ℃ and 60 ℃), fiberglass is carried out long-time cured successively, and not only can improve fiberglass and intermetallic adhesion, adhesive force, can reduce fiberglass and intermetallic internal stress again; With diamond cutter glass-cutting steel, not only tool wear is little, and the glass fiber reinforced plastic surface quality after the processing is good; And with optimum cutting parameter (cutting speed v=15～20m/s, cutting depth a
p=0.2～0.5mm, amount of feeding f=0.05～0.1mm/rev) winding direction by fiberglass cuts, and can effectively avoid fiberglass peeling in the processing, fall slag, swelling; At last the metal covering and the glass steel surface of housing end face carried out polishing turning, make the flatness of housing end face can reach 0.015mm with effective turning means.
In addition; It is the key factor that has a strong impact on the metal shell quality of coated with glass fibre reinforced plastics that fiberglass expands, therefore, and when the processed glass steel; Want ambient humidity in the strict control fiberglass process less than 25%; And guarantee the cleannes in the fiberglass process, and must not use any cooling, lubricating fluid, can effectively prevent the expansion of fiberglass.
The present invention adopts the ribbon glass ladle to cover metal shell, and manufacturing procedure is reasonable, and the outer fiberglass work in-process deformation that coats of metal shell is little, is difficult for peeling taking place, falling phenomenons such as slag, expansion; And the shell ends mask that processing obtains has good flatness.
