As described in Fig. 1 to Fig. 2, location-plate 2 is by laterally disposed transverse plate 21 and the company of fixation of vertical plate 22 vertically placed
Connect and form, the angle between vertical plate 22 and transverse plate 21 is 91 °；In step s 2, transverse plate 21 is horizontal positioned.
Location-plate 2 also includes cushion block 23, and cushion block 23 is fixed on transverse plate 21；In step s 2, cushion block 23 is supported in mould
Have in main body 1.Cushion block 23 is used to ensure that transverse plate 21 is horizontal positioned.
Location-plate 2 is made up of aluminum.In order to ensure the firmness of location-plate 2, strength can be taken in local location
Glue is fixed.
Below by taking the transformation of the double ribs of 56.6m wind electricity blade girders mould as an example, illustrate the rib preparation method of the present invention.
1st, prepare the precise information of accurate girder rib position, location-plate installation region 11 is pulled on die main body 1
With rib installation region 12, scribing position, which exceeds, requires width 6mm.
2nd, the rib installation region 12 in polishing outside is up to 10cm outside region, and coats and be stripped in location-plate installation region 11
Agent, it is easy to subsequently clear up；Reach the location-plate 2 of requirement, its corner edge in the placing height of location-plate installation region 11 and angle
Alignd with sharpened edge, the angle of vertical plate 22 is i.e. outside inclined 1 ° perpendicular to the ground for 91 °, and vertical plate 22 is along perpendicular to paper direction
Length be 1m, the elevation of vertical plate 22 is 7cm, fixes one layer of second release cloth in the outside glue spraying of vertical plate 22, is
Ensure the firmness of location-plate 2, in local location seccotine can be taken to fix.
3rd, suitable layer of cloth is cut, using two layers of 90 °/± 60 ° three axial cloth (i.e. setting cloth), width 17cm, by perpendicular
The angle region 3 formed to plate 22 and die main body 1, thirdly the top of axial cloth and the alignment of the top of vertical plate 22, using hand
Paste resin compound and hand paste is carried out to three axial cloth, and one layer of first release cloth is covered on resin compound surface, be bonded no sky
Bubble.After the completion of solidification, location-plate 2, the first release cloth are disassembled.
4th, fiberglass (i.e. cured layer 4) is formed after resin compound and three axial cloth solidifications, will according to the shape set
Fiberglass higher than elevation is cut off.
5th, the line of corresponding height is marked on the fiberglass of solidification, is subsequently poured into the mixture of mixed resin and aluminium powder,
Two is blocked with baffle plate, and is struck off the mixture in inclined-plane formed by the three of well cutting axial cloth using scraper plate, and inclined-plane is used de-
Filling block 5 is formed after the mixture solidification of the fiberglass die mould plate die moulded of mould cloth parcel, resin and aluminium powder.
6th, the type face of filling block 5, bad reparation again are examined.
7th, in the surface of filling block 5 laying glass fabric, release cloth and vacuum infusion resin mixture, remove after cured
Remove release cloth.
8th, gel coat is coated on the surface of filling block 5, polishing repeatedly is repaired, and ensures inner angle.
The present invention also provides a kind of wind electricity blade girder mould, and the both sides of die main body 1 are respectively fixed with a rib, its
One or both of rib be made up of above-mentioned wind electricity blade girder mould rib preparation method.
The girder mould for the double ribs produced by above-mentioned wind electricity blade girder mould rib preparation method, rib can be helped
Girder short transverse plastotype is helped, girder perfusion resin waste can be reduced during girder is made.Use the girder of single block border
Mold Making girder, uneven glass fabric can be cut away, therefore to ensure width of main beam, raw material glass fiber cloth
Width can increase, and corresponding resin can also increase.Using double ribs, because double rib girders are identical with mould type shape, therefore not
Need to cut again.So, after girder shaping, main mould is used directly for, reduces the girder turnaround time, original can be shortened
Material width, resin demand is reduced, reduce cutting dust, improve workshop condition, reduced girder turnover, reduce because turnover causes to lead
The risk of beam damage.
The present invention is not limited to the above-described embodiments, no matter making any change in its shape or structure, all falls within this hair
Within bright protection domain.Protection scope of the present invention is defined by the appended claims, and those skilled in the art exists
On the premise of without departing substantially from principle and essence of the invention, various changes or modifications, but these can be made to these embodiments
Change and modification each fall within protection scope of the present invention.
