Background technique
The molding technique of mainstream wind electricity blade at present is required to make auxiliary blade molding bonding in trailing edge region
Bonding angle.
Existing trailing edge bonding angle forming method is viscous using dedicated rear after blade shell curing molding
The hand for connecing angle former or formpiston progress bonding angle pastes work, with popularizing for large scale fan blade, corresponding rear bonding angle production
Length is also increasingly longer, while the height for making bonding angle is smaller and smaller, and bring pastes the operating space of bonding angle increasingly
Small, it is narrow that narrow space using former pastes bonding angle operating space, can not ensure that bonding angle pastes quality, is pasted using formpiston
Rear mold processed takes out difficulty, is easy to injure the bonding angle being ready for and blade body after taking out reluctantly.
Simultaneously as being perfused when being spread rear bonding angle with blade layer using core model mode, there are bonding angle core material water conservancy diversion
Speed is fast, and the auxiliary beam unidirectional cloth of region lower leaflet rear is caused to outflank the appearance of infiltration problem.
Therefore, it is necessary on the basis of existing technology, research and develop a kind of easily operated while can ensure product matter
The wind turbine blade rear bonding angle forming method of amount.
Summary of the invention
It is an object of the invention to overcome deficiency in the prior art, a kind of rear edge of wind turbine blade bonding angle molding dress is provided
It sets, is easy to constructing operation stable product quality simultaneously.
To solve prior art problem, the invention discloses a kind of rear edge of wind turbine blade bonding angle molding machines, comprising:
One mold, with one for blade forming type chamber；
One fiberglass cloth A；
One fiberglass cloth B；
One surface is coated with the foam pellet of fiberglass cloth C；And
One demoulding layer of cloth；
Blade is contained in type chamber, and fiberglass cloth A is laid on the surface of the trailing region of blade, the setting of foam pellet
In the surface of the fiberglass cloth A for the trailing region for being located at blade；Fiberglass cloth B is layed in the surface of foam pellet simultaneously
Foam pellet is covered, demoulding layer of cloth is layed in the surface of fiberglass cloth B.
Preferably,
The laying range of fiberglass cloth A exceeds laying range 50mm~100mm of foam pellet.
Preferably,
Foam pellet and the surface contacted fiberglass cloth B be provided with several difference along its length with width direction
Fluting, the depth of fluting are 2mm, and the separation of fluting along its length is 20mm, the separation of fluting in the width direction
For 20mm.
Preferably,
Fluting along its length intersects with fluting in the width direction, and infall setting perforation is another to foam pellet
Through-hole on one side.
Preferably,
The laying range of fiberglass cloth B exceeds laying range 60mm~110mm of foam pellet.
Preferably,
The laying range for demoulding layer of cloth exceeds the laying range 50mm of fiberglass cloth B.
The invention has the benefit that the production to carry out trailing edge bonding angle by core model mode provides advantageous item
It is unstable to effectively prevent, hand paste bubble cumbersome using former or formpiston production bonding angle bring sequence of operations, size for part
The problems such as difficult is taken out with mold, the manufacture difficulty of bonding angle is reduced and improves product quality.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Appended drawing reference:
1 mold；1a type chamber；2 blades；3 fiberglass cloth A；4 foam pellets；5 fiberglass cloth C；6 glass fibres
Layer of cloth B；7 demoulding layer of cloths.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of rear edge of wind turbine blade bonding angle molding machine, including mold 1, fiberglass cloth A3, glass
Glass scrim cloth B6, foam pellet 4 and demoulding layer of cloth 7.Mold 1 has one for the molding type chamber 1a of blade 2, foam pellet 4
Surface is coated with fiberglass cloth C5.Core model needed for foam pellet 4 serves as the production of 2 rear bonding angle of blade, is laid with model
Enclose the region for needing to do bonding angle for entire 2 rear of blade, when laying need to be sturdy with the rear of blade 2.
Blade 2 is contained in type chamber 1a, and fiberglass cloth A3 is laid on the surface of the trailing region of blade 2, foam core
Block 4 is set to the surface of the fiberglass cloth A3 positioned at the trailing region of blade 2；Fiberglass cloth B6 is layed in glass fibers
It ties up the surface of layer of cloth A3 and covers foam pellet 4, demoulding layer of cloth 7 is layed in the surface of fiberglass cloth B6.
In use, first having been cured one layer of the trailing region surface laying for finishing and removing the blade 2 of auxiliary material on mold 1
Fiberglass cloth A 3, then the foam pellet 4 for being wrapped fiberglass cloth C5 is close to trailing edge laying, later
Layer of glass layer of cloth B6 is integrally laid on the foam pellet 4 of package fiberglass cloth C5 again, finally in glass
