Abstract
The invention belongs to the field of manufacturing of composite materials and relates to a method for repairing an R corner of a tool. The method includes the following steps that an R area to be repaired is cleaned and polished to be rough; adhesives and a reinforcing material are mixed to form a mixed material; the mixed material adheres to the R area to be repaired; the redundant mixed material is scraped off along the tool, and the R corner meeting the design requirement is obtained; and then the mixed material is solidified to form an R corner standby area.
Description
Technical field
The invention belongs to matrix material and manufacture field, it relates to a kind of method repaired for frock R angle.
Background technology
It is the big difficult point that frock is repaired that the R angle misrun of matrix material frock is repaired always, use conventional repair welding to repair to be difficult to reach service requirements, and operation easier is big, use limitation is many, and after repairing, machine adds that cost is very high and effect is not good, and after repairing, frock surface porosity factor and planeness all do not reach acceptance requirement, therefore once run into R angle misrun and repairing, basic frock just needs again to have manufactured, and in order to improve this present situation, existing one effective ways of being badly in need of solve this difficult problem.
Summary of the invention
Technical problem to be solved by this invention is: proposing a kind of handled easily, the method for repairing and mending of the R angle misrun of economical and effective, can meet frock service requirements after repairing.
The technical scheme of the present invention is: planting the method being used for frock R angle and repairing, the step of repairing is as follows:
The present invention provides a kind of method repaired for frock R angle, it is characterised in that, comprise the following steps:
1.1, R district to be reprocessed is carried out cleaning and polishes coarse;
1.2, mix with strongthener with tackiness agent, form mixing material;
1.3, mixing material is bonded in R district to be reprocessed;
1.4, along frock, unnecessary mixing material is struck off, obtain the R angle of design requirements, then solidify mixing material, form Hou Bu region, R angle.
Further, also comprise the following steps after step 4:
The glue clothing that region surface covers the thin plastic adhesive tape of lid layer or equivalence is mended behind R angle. Adopt the glue clothing of thin plastic adhesive tape or equivalence. Surface effect can be improved, it is to increase product surface smooth finish.
Further, strongthener comprises aluminium powder, carbon fiber powder or glass fiber powder. The work-ing life reprocessing frock can be promoted, strengthen and reprocess effect.
Further, step 4 adopts R rule or India-rubber strip to be struck off by mixing material.
Further, R district to be reprocessed is polished two simultaneously and closes region, angle by step 1. Hou Bu region, R angle can be carried out spacing and fixing.
The invention has the beneficial effects as follows: the present invention is a kind of method repaired for frock R angle, when the change in design of frock R angle, it is possible to R angle misrun situation repaired fast, it is possible to greatly improve the frock repair cycle, saves and reprocesses cost; Test proves, the present invention can reduce frock repair cost more than 300%, and the production cycle shortens more than 200%.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of embodiment of frock R angle of the present invention repairing method;
Fig. 2 is the schematic diagram of another kind of embodiment that frock R angle is repaired in the present invention;
Embodiment
Below the specific embodiment of the present invention is described in further details.
The present invention provides a kind of method repaired for frock R angle, and step is as follows:
R district to be reprocessed is used acetone or other organic solvent to clean by 1.1, and by coarse for R district to be reprocessed polishing, polish two simultaneously and close region, angle, it may also be useful to acetone clean totally air-dry after carry out next step and operate;
1.2 uses tackiness agent (thermal structure glue) mix with aluminium powder or other equivalence strongthener such as glass fiber powder and carbon fiber powder;
1.3 deployed tackiness agent and strongthener be bonded in R district to be reprocessed and previously polished close region, angle;
Unnecessary glue liquid mixture is struck off along frock by 1.4 with the special equivalence instrument of R rule or other, the circular hard object with this identical size in R angle can also be used to be placed on repairing area, make vacuum-bag process and go out R angle, be just cured according to selected adhesive solidification condition after trimming R angle;
After 1.5 solidifications, repairing area surface is processed, more than 400# waterproof abrasive paper is used to carry out sanding and polishing, in the work-ing life reprocessing frock to promote, strengthen and reprocess effect, it is possible at the epoxy resin glue clothing of the thin Teflon adhesive tape of rework area surface coverage one layer or spraying equivalence;
Embodiment 1
See Fig. 1, being repaired at R angle shown in certain model fixed cover, its step repaired is as follows:
1. will wait that R district to be reprocessed uses acetone to clean, and by coarse for R region to be repaired polishing, it may also be useful to acetone clean totally air-dry after carry out next step operation;
2. use tackiness agent 2080 glue to mix with aluminium powder;
3. 2080 deployed glue and aluminium powder uniform mixture are placed on R district to be reprocessed;
4. unnecessary glue liquid mixture is struck off along frock with �� 5R rule;
5. after solidification, repairing area surface is processed, it may also be useful to 400# waterproof abrasive paper carries out sanding and polishing, in order to promote the work-ing life reprocessing frock, strengthen and reprocess effect, at the thin Teflon adhesive tape of rework area surface coverage one layer;
Embodiment 2
Being repaired at certain model retaining plate R angle shown in Fig. 2, its step repaired is as follows:
1. will wait that R district to be reprocessed uses acetone and by coarse for R region to be repaired polishing, polish two simultaneously and close region, angle, it may also be useful to acetone clean totally air-dry after carry out next step operation;
2. use tackiness agent EA9309.3 to mix with carbon fiber powder;
3. the bing after deployed EA9309.3 and carbon fiber powder Homogeneous phase mixing is placed on R district to be reprocessed and previously polished close region, angle;
4. use and it is placed on repairing area with the circular hard object of this identical size in R angle, make vacuum-bag process and go out R angle, be just cured according to EA9303.3 condition of cure after trimming R angle;
5. after solidification, repairing area surface is processed, it may also be useful to 400# waterproof abrasive paper carries out sanding and polishing, in order to promote the work-ing life reprocessing frock, strengthen and reprocess effect, coat one layer of epoxy resin glue clothing.
