In other embodiment, described housing segmentation can also have other forms of variation, described housing segmentation can be independent to carry out segmentation by housing mould, and then carries out form step, and it is not limited to the above-mentioned mode that housing segmentation and form need to be carried out in the lump.In the time that housing carries out segmentation separately, the order of described crossbeam segmentation, housing segmentation and these three steps of web segmentation can be exchanged arbitrarily, as long as the step that guarantees crossbeam segmentation and housing segmentation is before form step.
S104, web segmentation: take described segmented line as standard, each predeterminable range place in the front and back apart from this segmented line, is vertically divided into three sections of blade tip web, blade web and blade root webs by web at its length direction;
Refer to Fig. 9, after web form, described web is carried out to segmentation.Similarly, take described segmented line 20 as standard, this segmented line 20 is identical with above-mentioned segmented line, and the segmented line 20 of crossbeam, housing and web is same segmented line 20.One predeterminable range place, front and back in this segmented line 20 is vertically divided into blade tip web, blade web (removing in figure) and blade root web by described web at its length direction, and described predeterminable range can adjust according to actual conditions.In the present embodiment, described predeterminable range is 100mm, before and after described segmented line, described web is divided into blade tip web 41, blade web (not shown) and blade root web 43 by each 100mm place, blade tip web 41, blade web and blade root web 43 after segmentation all need the section of polishing, described blade tip web 41 and blade root web 43 use in following vane mold matching, and described blade web need to send to when assemble at unit place and assemble with delivery.
S105, vane mold matching: by blade tip web and blade root web respectively interval one distance be placed in blade tip crossbeam and the enterprising sector-style electricity of the blade root crossbeam vane mold matching after form, wherein, described distance equals the length of described blade web;
Please continue referring to Fig. 9, the key point of described vane mold matching step is mainly on the putting position of described web, after described blade tip web 41 and blade root web 43 are placed on described blade tip crossbeam 21 and blade root crossbeam 22, parallel distance between them should be with described blade web equal in length, if blade web is 200mm, the section flat row distance of described blade tip web 41 and blade root web 43 is 200mm, is also that the section identity distance of described blade tip web 41 and blade root web 43 is from being 100mm with a point distance for broken string.
S106 blade molding: the wind electricity blade after molding is segmented wind electricity blade, described segmented wind electricity blade comprises blade root wind electricity blade and leaf tip wind electricity blade.
Refer to Figure 10, after blade molding, blade root wind electricity blade 51 is extracted out from leaf tip wind electricity blade 52, wind electricity blade 50 after molding is segmented wind electricity blade 50, before described blade root wind electricity blade 51 is extracted out from leaf tip wind electricity blade 52, can carry out mark and assemble with aid in later, check cleaning cross sections, guarantee each fracture surface roughness so that follow-up assembling is bonding, and carry out dust prevention.
The utility model embodiment, by housing and web at its length direction vertical fragmentation, take staggered floor segmentation (staggered floor separation laying) to make blade tip crossbeam and blade root crossbeam form the staggered floor face of inclination on crossbeam, thereby make in follow-up assembly process, increase the bond area of blade tip crossbeam and blade root crossbeam, increase their bonding strength, solved big-length subsection blade that in prior art, major diameter wind wheel is taked due to the low problem of bonding strength that adopts overall segmentation to cause.
