Abstract
The invention provides a fan blade web manufacturing method capable of avoiding lightning conductor adhesion. According to the method, a main lightning conductor is fixed on a web through a way of embedding and integral solidifying. The method comprises the following specific steps: manufacturing a web female die with a groove reserved for holding a main lightning conductor; and when manufacturing the web by using the web female die, firstly spraying a release agent, placing a release cloth, laying glass fiber cloth for reinforcing, then laying the main lightning conductor with an insulating sleeve into the groove, and finally laying a web structural layer and assistant materials according to a conventional web manufacture technology; pouring resin into the web female die, and solidifying and molding so that the glass fiber cloth, the main lightning conductor and the web are solidified into a whole. By adopting the method, the manual adhering processes are reduced, the production efficiency is improved, the main lightning conductor adherion quality and use stability are improved.
Description
Technical field
The present invention relates to a kind of preparation method of fan blade web, particularly a kind of preparation method of exempting from the bonding fan blade web of lightning conducter.
Background technology
When fan blade was installed lightning protection system, main lightning conductor need be bonded on the web, and the arrester of before the housing matched moulds, will taking shelter from the thunder again is connected with main lightning conductor and is conducting to ground.In the prior art, the bonding way of main lightning conducter and web is: after web is made moulding, use hand to stick with paste technology and bond to lightning conductor on web (TE) limit with hand paste resin.Its defective is: this operational sequence is complicated, and product structure intensity is low, operating personnel's hand takes place easily stick with paste bonding proportioning error.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to prior art, provides that a kind of technological design is more reasonable, easy to operate, the preparation method of exempting from the bonding fan blade web of lightning conducter of fixation.
Technical problem to be solved by this invention is to realize through following technical scheme.The present invention is a kind of preparation method of exempting from the bonding fan blade web of lightning conducter, is characterized in, this method adopts mode pre-buried and that one is solidified that main lightning conductor is fixed on the web, and its concrete steps are following:
(1) makes the web former of reserving lightning conducter placement groove earlier; When using this web former to make web; Play earlier releasing agent, place release cloth, lay then and strengthen using glass cloth; Auxilliary being located in the groove of main lightning conductor that will have insulation sleeve again is at last by auxilliary web structure layer and the auxiliary material established of the conventional manufacture craft of web;
(2) perfusion resin in the web former, curing molding is solidified togather glass cloth, main lightning conductor and web.
In the step (1) of the preparation method of exempting from the bonding fan blade web of lightning conducter of the present invention: the groove footpath of said groove is preferably than the big 2-4mm of main lightning conductor diameter.Like this, can effectively prevent the generation of rich resin in the filling process.
In the step (2) of the preparation method of exempting from the bonding fan blade web of lightning conducter of the present invention: in the web former, preferably adopt the priming by vacuum method during perfusion resin.Like this, it is simple to operate to make full use of priming by vacuum, product structure intensity advantages of higher.
Common process in " at last by auxilliary web structure layer and the auxiliary material established of the conventional manufacture craft of web " described in the present invention can be disclosed any web manufacture craft in the prior art.The web structure layer generally comprises core and several layers enhancement layer glass cloth of web etc.Can adopt priming by vacuum method conventional in the prior art during vacuum method perfusion resin.
Compared with prior art, the inventive method can realize having the minimizing operation, and is simple to operate, improved production efficiency, characteristics such as product structure intensity height.This method has not only reduced hand and has stuck with paste bonding operation, has improved bonding quality of main lightning conductor and stability in use simultaneously, reduces operating personnel's hand and sticks with paste bonding proportioning error risk, has guaranteed the lightning-arrest effect of fan blade.
The specific embodiment
Below further concrete technical scheme of the present invention is described,, and do not constituted restriction right of the present invention so that the technical staff in present technique field understands the present invention further.
Embodiment 1, and a kind of preparation method of exempting from the bonding fan blade web of lightning conducter, this method adopt mode pre-buried and that one is solidified that main lightning conductor is fixed on the web, and its concrete steps are following:
(1) makes the web former of reserving main lightning conductor placement groove earlier; When using this web former to make web; Play earlier releasing agent, place release cloth, lay then and strengthen using glass cloth; Auxilliary being located in the groove of main lightning conductor that will have insulation sleeve again is at last by auxilliary web structure layer and the auxiliary material established of the conventional manufacture craft of web;
(2) perfusion resin in the web former, curing molding is solidified togather glass cloth, main lightning conductor and web.
Embodiment 2, and embodiment 1 is described to exempt from the step (1) of preparation method of the bonding fan blade web of lightning conducter: the groove footpath of said groove is than the big 2mm of main lightning conductor diameter.
Embodiment 3, and embodiment 1 is described to exempt from the step (1) of preparation method of the bonding fan blade web of lightning conducter: the groove footpath of said groove is than the big 4mm of main lightning conductor diameter.
Embodiment 4, in the step (2) of any one described preparation method of exempting from the bonding fan blade web of lightning conducter of embodiment 1-3: in the web former, adopt the priming by vacuum method during perfusion resin.
Claims (3)
1. a preparation method of exempting from the bonding fan blade web of lightning conducter is characterized in that, this method adopts mode pre-buried and that one is solidified that main lightning conductor is fixed on the web, and its concrete steps are following:
(1) makes the web former of reserving main lightning conductor placement groove earlier; When using this web former to make web; Play earlier releasing agent, place release cloth, lay then and strengthen using glass cloth; Auxilliary being located in the groove of main lightning conductor that will have insulation sleeve again is at last by auxilliary web structure layer and the auxiliary material established of the conventional manufacture craft of web;
(2) perfusion resin in the web former, curing molding is solidified togather glass cloth, main lightning conductor and web.
2. the preparation method of exempting from the bonding fan blade web of lightning conducter according to claim 1 is characterized in that, in the step (1): the groove footpath of said groove is than the big 2-4mm of main lightning conductor diameter.
3. the preparation method of exempting from the bonding fan blade web of lightning conducter according to claim 1 and 2 is characterized in that, in the step (2): in the web former, adopt the priming by vacuum method during perfusion resin.
