Abstract
The present invention relates to bound edge bag pressure devices outside a kind of wind electricity blade, including bound edge layer of cloth and release cloth outside the blade that outside pastes in blade front and rear edge, and the outer bound edge layer of cloth of blade is pasted along die parting line, and is covered with release cloth, and ventilative suction rubber mat is covered on the release cloth;Ventilative to inhale the sealing joint strip for being equipped on the outside of rubber mat and being adhesive in blade surface layer, which has vacuum bag film, and vacuum bag film covers sealing joint strip;The exhaust tube there are two inverted " t " type shape is oppositely arranged in vacuum bag film, which connects evacuator, and evacuator ensures that pumping negative pressure is less than -0.08ka;Exhaust tube is connected to vacuum bag film.The present invention reduces gel content, is less prone to layering, reduces manual skill dependence, improves product quality.
Description
Technical field
The present invention relates to blade production technical field, the outer bound edge bag pressure device of especially a kind of wind electricity blade.
Background technology
With flourishing for wind-power electricity generation, the problem of fan blade, also gradually appears, problem occur it is most be exactly before
Rear cracks.Currently, the upper-lower casing generally use structure glue of blade is bonded, the position hand paste after demoulding in front and rear edge is outer
Bound edge is reinforced, and traditional hand paste technique gel content is high, keeps the structure sheaf of bound edge layer of cloth rigidly big, causes to hold in the process of running
Easily it is layered;Sense of responsibility etc. when traditional hand paste technique opponent pastes skill master degree and the operation of personnel simultaneously has very
High requirement, thus can cause hand paste quality there are prodigious uncertainties.
Invention content
Technical problem to be solved by the invention is to provide a kind of reduction gel contents, are less prone to layering, reduce artificial skill
Energy dependence improves the outer bound edge bag pressure device of wind electricity blade of product quality.
To solve the above problems, a kind of outer bound edge bag pressure device of wind electricity blade of the present invention, including blade front and rear edge
The outer bound edge layer of cloth of blade and release cloth that interior outside pastes, it is characterised in that:It is covered with demoulding on the outer bound edge layer of cloth of the blade
Cloth is covered on the release cloth and ventilative inhales rubber mat;The ventilative rubber mat outside of inhaling is equipped with the sealing joint strip for being adhesive in blade surface layer,
The sealing joint strip paste outside has vacuum bag film;It is relatively set with exhaust tube in the vacuum bag film, pumping pipe end connection
Evacuator, and inner end is connected to the vacuum bag film.
The outer bound edge layer of cloth of the blade is pasted along die parting line.
The vacuum bag film covers the sealing joint strip.
The exhaust tube is set as T-shape shape.
The evacuator ensures that pumping negative pressure is less than -0.08ka.
Compared with the prior art, the present invention has the following advantages:
(1)The present invention will be covered ventilative suction rubber mat, and be passed through fluid sealant due to bound edge layer of cloth laying release cloth outside blade on release cloth
Item pastes vacuum bag film, makes vacuum bag film covering is ventilative to inhale rubber mat, is extracted out the gas in vacuum bag film by exhaust tube, demoulding
Cloth is tightly attached on the outer bound edge layer of cloth of blade, and ventilative rubber mat of inhaling presses release cloth, and vacuum bag film covering carries out bag pressure, with solidification path
The raising of degree, reduces vacuum degree in due course, so that the gel content of the outer bound edge layer of cloth of blade is reduced, structure sheaf rigidly reduction, is less prone to
Layering.
(2)The present invention forms confined space after being covered due to vacuum bag film, and evacuator is by exhaust tube by vacuum bag film
Interior air extraction, realizes and completes bag pressure under vacuum-pumping conditions, avoid hand paste technical process employee skill Grasping level difference with
And no responsibility heart when operation, the dependence of employee skill is reduced, ensure that the consistency of product quality.
Description of the drawings
Specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural diagram of the present invention.
In figure:1. the outer bound edge layer of cloth of blade, 2. release cloths, 3. ventilative suction rubber mats, 4. sealing joint strips, 5. vacuum bag films, 6.
Exhaust tube, 7. evacuators.
Specific implementation mode
As shown in Figure 1, a kind of outer bound edge bag pressure device of wind electricity blade, including outside outside pastes in blade front and rear edge blade
Bound edge layer of cloth 1 and release cloth 2, bound edge layer of cloth 1 pastes blade along die parting line outside, and is covered with release cloth 2,2 overlying of release cloth
It is stamped ventilative suction rubber mat 3;Ventilative 3 outside of rubber mat of inhaling is equipped with the sealing joint strip 4 for being adhesive in blade surface layer, outside the sealing joint strip 4
It is pasted with vacuum bag film 5, and vacuum bag film 5 covers sealing joint strip 4;Inverted " t " type shape there are two being oppositely arranged in vacuum bag film 5
Exhaust tube 6,6 end of exhaust tube connect evacuator 7, evacuator 7 ensure pumping negative pressure be less than -0.08ka;Exhaust tube 6
It is connected to vacuum bag film 7.
In use, outside pastes bound edge layer of cloth 1 outside blade in the bound edge position needed for the front and rear edge of wind power generation blade, paste
It is laid with release cloth 2 on bound edge layer of cloth 1 outside blade after the completion of system to cover, is laid with one layer of ventilative suction glue after covering on release cloth 2
Release cloth 2 and bound edge layer of cloth 1 outside blade are completely covered for felt 3, ventilative rubber mat 3 of inhaling;Then 3 size of rubber mat is inhaled according to ventilative,
It is pasted in vacuum bag film 5 from ventilative suction rubber mat 3 along the sealing joint strip 4 of side 10-20mm spacing, vacuum bag film 5 is covered in ventilative
It inhales in rubber mat 3, sealing joint strip 4 is adhesive in blade surface layer;Ensure that evacuator 7 is evacuated negative pressure and is less than -0.08ka after covering, passes through
Exhaust tube 6 extracts the air in vacuum bag film 5 out, and air detaches process since underbalance effect makes release cloth 2 be tightly attached to outside blade
On bound edge layer of cloth 1, ventilative rubber mat 3 of inhaling presses release cloth 2, with the raising of curing degree, reduces vacuum degree, vacuum bag film in due course
The gel content of bound edge layer of cloth 1 outside blade is reduced, structure sheaf rigidly reduction, is less prone to layering, ensure that product matter by 5 bags of pressures
The consistency of amount.
