Embodiment Construction

[0015] like figure 1 , 2 As shown, the processing method of the high-precision thin-walled metal shell coated with glass fiber reinforced plastics, the processing steps are as follows:

[0016] 1) In the step of winding and coating, the FRP 2 is made into a strip shape, and the surface is coated with glue and wound on the surface of the metal shell 1 layer by layer;

[0017] 2), FRP curing step, first curing at 80°C for 5-6 hours; then curing at 60°C for 4-6 hours;

[0018] 3), the step of cutting the surface of FRP, cutting the surface of FRP with a diamond tool, and ensuring that the cutting direction of the diamond tool is consistent with the winding direction of the ribbon FRP, and the cutting parameters are cutting speed v=15~20m / s, cutting depth a p =0.2~0.5mm, feed f=0.05~0.1mm / rev;

[0019] 4), the finishing process step, finishing turning the metal surface and the FRP surface of the shell end face, first processing the FRP surface of the shell end face with a diamo...

Abstract

The invention relates to a method for processing metal coated with glass fibre reinforced plastics, in particular to a method for processing a high-precision thin-wall metal shell coated with glass fibre reinforced plastics. The method solves the problems that the binding force and the adhesive force between the glass fibre reinforced plastics and the metal are small, phenomena of peeling, scaling off and expanding are easy to generate in processing, the planeness of a plane formed by two materials of the glass fibre reinforced plastics and the metal is poor and the like existing in metal shells coated with the glass fibre reinforced plastics and processed by the prior method. 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 [0001] The invention relates to a metal processing method for covering glass steel, in particular to a processing method for a high-precision thin-walled metal shell covering glass steel. Background technique [0002] FRP coating on the metal surface can play the role of heat insulation, heat insulation, and anti-radiation, and has good high and low temperature insulation, heat insulation, and anti-radiation characteristics, and the heat insulation temperature can reach above 1000°C. In the machinery industry, metal shells coated with glass fiber reinforced plastics are rarely used, and have not been used in aviation and navigation. At present, they are only used in domestic aerospace. The domestic processing method of coating FRP on the surface of the metal shell is still in the exploratory stage. The current processing method is to make the FRP into a cloth shape, and then wrap the surface of the metal shell layer by layer after the surface is coated with g...
