Description
Technical field
The invention mainly relates to the processing technology of thick product frp layer plywood more particularly to a kind of thick product frp layers
Plywood cutting polishing processing method.
Background technique
Because of the variation of external environment in glass reinforced plastic curing process, the heat release of itself, mould in resin solidification reaction process
Tool, auxiliary material heating conduction difference lead in the practical solidification process of laminate that there are temperature gradients；Non-uniform temperature field makes respectively
Resin and non-concurrent solidification in laying, so as to cause frp layer plywood, there are residual stress and residual deformation.For the ease of
The flatness that demoulding and laminate are glued, the frp layer plywood end after solidification can be higher by housing mould a part, therefore need
Cutting polishing is carried out to the frp layer plywood end for being higher by housing mould a part, to guarantee flatness, but after solidification
Frp layer plywood generates violent plastic deformation in cutting bruting process, and there are biggish ess-strain and localized hyperthermias.
Existing conventional method is to be also easy to produce micro-crack and larger residual after solidification using polishing after the mechanically direct transverse cuts by the raised area
Residue stress, stress and deformation cannot discharge when routine is cut, and easily make the lower frp layer plywood of Interlaminar shear strengths itself
When cutting polishing.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of easy to operate, processing quality
Height can discharge stress and deformation in advance, can prevent that the thick product frp layer plywood of micro-crack and larger residual stress is cut
Cut polishing processing method.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of thickness product frp layer plywood cutting polishing processing method, comprising the following steps:
S1: vacuum bag film is scratched with tool beyond the component that is higher by of housing mould upper flange platform in thick product frp layer plywood；
S2: marking is carried out being higher by component face to be processed, determines at least two mark lines；
S3: carrying out vertical grooving along mark line with cutting machine, forms shallow slot, the length of shallow slot with need processing length consistent；
S4: polishing to shallow slot region surface with angle grinder, until when shallow slot i.e. will be invisible；
S5: keeping step S3 and S4 circulation to carry out, until molding bonding plane needed for being formed after being higher by component polishing.
As a further improvement of the above technical scheme:
In step s3, cutting machine deflectable angle, θ in vertical plane, < ± 45 ° θ.
In step s3, cutting machine is in the deflectable angle beta of horizontal plane, < ± 45 ° β.
In step s3, the depth of shallow slot is set as h, 1mm < h < 5mm.
In step s3, the width of shallow slot is set as b, 2mm < b < 4mm.
In step s 5, molding bonding plane height molds bonding plane height not above flange platform die joint height 2mm
Flange platform die joint height 5mm can be lower than.
In step S1 into step S5, it is ensured that be higher by component face temperature to be processed lower than 40 DEG C, surface hardness Barcol is higher than
50HBa。
Compared with the prior art, the advantages of the present invention are as follows:
Thick product frp layer plywood cutting polishing processing method of the invention, S1: exceeds shell in thick product frp layer plywood
The component that is higher by of mould upper flange platform scratches vacuum bag film with tool；S2: carrying out marking being higher by component face to be processed,
Determine at least two mark lines；S3: vertical grooving is carried out along mark line with cutting machine, forms shallow slot, the length and needs of shallow slot
Processing length is consistent；S4: polishing to shallow slot region surface with angle grinder, until when shallow slot i.e. will be invisible；S5: it protects
It holds step S3 and S4 circulation to carry out, until molding bonding plane needed for being formed after being higher by component polishing.Using this method, make whole height
Component forms Slice by slice cutting polishing out, i.e., first carries out vertical grooving in face to be processed, a plurality of shallow slot is formed, to discharge stress in advance
And face to be processed is separated into a plurality of strip shape body by deformation, each shallow slot, is then carrying out polishing strip to shallow slot region surface
Body, it is reciprocal with this, until molding bonding plane needed for being formed after being higher by component polishing.More traditional will be higher by portion using mechanically direct
For the mode polished after part transverse cuts, using Slice by slice cutting polishing mode, stress and deformation can be discharged in advance, can be prevented
Thick product frp layer plywood generates micro-crack and larger residual stress when cutting polishing, moreover it is possible to avoid disposably cutting institute's band
The localized hyperthermia's problem come, it is easy to operate, improve the Forming Quality of thick product frp layer plywood.
