Abstract
The invention discloses glass fiber yarn pre-invasion legal system and make trailing edge reinforcement technique, multiple glass fiber yarn yarn group is first neatly placed on creel by it, many glass fiber yarns are under the traction of draw-gear, pass through tension force stick, steeping vat is entered after bushing and collection yarn device complete proper alignment, yarn fully infiltrates resin in steeping vat, resin more for glass fiber yarn is first extruded by Extruded roller by the yarn infiltrated after resin from glass fiber yarn, then after controlling yarns resins content by tubular die, by the yarn twisted bunchy after plastic squeeze, the yarn of twisted bunchy is required to carry out cutting according to design length, then put into trailing edge mould and shakeout laying, until complete the filling to trailing edge mould, finally wait for that the yarn infiltrating resin is mold curing, the demoulding obtains required trailing edge reinforcement.
Description
[technical field]
The present invention relates to glass fiber yarn pre-invasion legal system and make trailing edge reinforcement technique.
[background technology]
Trailing edge reinforcement is positioned at trailing edge side, and generally from root of blade, until blade tip, it is mainly used in the rigidity and the stability that improve whole blade, guarantees that blade there will not be the serious problems such as flexing unstability, cracking in running.
The MW class blade produced both at home and abroad at present generally all adopts and will uniaxially directly be layered in blade shell by glass fabric, form together with blade shell, and the process of this making trailing edge reinforcement exists following shortcoming:
1, the width due to trailing edge reinforcement is general narrower, and instillation process is generally only suitable for the relatively less trailing edge reinforcement of the number of plies.
2, because uniaxially glass fabric distortion is relatively little, for avoiding the appearance of trailing-edge fold, instillation process is generally only applicable to the relatively little blade profile of trailing edge curvature.
3, because uniaxially glass fabric needs to carry out lay by layer, so instillation process is generally only applicable to the blade profile of trailing edge interface shape relatively rule.
Therefore, be necessary to solve as above problem.
[summary of the invention]
Instant invention overcomes the deficiency of above-mentioned technology, provide a kind of glass fiber yarn pre-invasion legal system and make trailing edge reinforcement technique, it realizes the production of trailing edge reinforcement in irregular shape by laying filling mode.
For achieving the above object, present invention employs following technical proposal:
Glass fiber yarn pre-invasion legal system makes trailing edge reinforcement technique, includes following steps:
A, enter yarn: be arranged in parallel by many glass fiber yarns and line up sheet and export;
B, impregnation: the yarn lining up sheet is input in steeping vat and fully infiltrates resin;
C, plastic squeeze control resin content: carry out plastic squeeze to the yarn after infiltrating resin, control the resin content in yarn;
D, laying are filled: by the yarn twisted bunchy after plastic squeeze, required to carry out cutting by the yarn of twisted bunchy, then put into trailing edge mould and shakeout laying, until complete the filling to trailing edge mould according to design length;
E, solidification: the yarn infiltrating resin is mold curing at trailing edge;
F, the demoulding: deviate from from trailing edge mould by trailing edge reinforcement, obtain required trailing edge reinforcement.
As mentioned above, in step, described many glass fiber yarns are under the traction of draw-gear, successively complete to be arranged in parallel by tension force stick, bushing and collection yarn device and line up sheet output from creel.
As mentioned above, in step C, yarn, by the preliminary plastic squeeze of plastic squeeze rod, then controls resin content by tubular die.
Compared with prior art, the invention has the beneficial effects as follows:
1, raw material use glass fiber yarn, can fill erose trailing edge mould, can operate in the trailing edge mould that width is narrower.
2, many glass fiber yarns are be arranged in parallel line up sheet export, be convenient to the traction of postorder and neat twisted bunchy, be convenient to shakeout laying.
3, control resin content by plastic squeeze, be convenient to the resin content reaching designing requirement, control the quality stability of trailing edge reinforcement.
4, the yarn twisted bunchy after resin is infiltrated by many, the yarn of twisted bunchy is required to carry out cutting according to design length, then put into trailing edge mould and shakeout laying, until trailing edge mold filling completes, its can the irregular trailing edge mould of suitable shapes filling and make the trailing edge reinforcement of many sizes.
5, because yarn has infiltrated resin and mold curing at trailing edge, so the trailing edge reinforcement that after the demoulding, available can be good, trailing edge can be avoided to occur possibility of fold, the service life of raising blade.
[accompanying drawing explanation]
Fig. 1 is flow chart of the present invention.
[detailed description of the invention]
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technical staff of the same trade:
As shown in Figure 1, glass fiber yarn pre-invasion legal system makes trailing edge reinforcement technique, includes following steps:
101, yarn is entered: be arranged in parallel by many glass fiber yarns and line up sheet output;
102, impregnation: the yarn lining up sheet is input in steeping vat and fully infiltrates resin;
103, plastic squeeze controls resin content: carry out plastic squeeze to the yarn after infiltrating resin, control the resin content in yarn;
104, laying is filled: by the yarn twisted bunchy after plastic squeeze, is required to carry out cutting by the yarn of twisted bunchy, then put into trailing edge mould and shakeout laying, until complete the filling to trailing edge mould according to design length;
105, solidify: the yarn infiltrating resin is mold curing at trailing edge;
106, the demoulding: deviate from from trailing edge mould by trailing edge reinforcement, obtains required trailing edge reinforcement.
This case detailed process is as follows:
Before work, get out trailing edge reinforcement mould, during the manufacturing, first multiple glass fiber yarn yarn group is neatly placed on creel, many glass fiber yarns are under the traction of draw-gear, pass through tension force stick, steeping vat is entered after bushing and collection yarn device complete proper alignment, yarn fully infiltrates resin in steeping vat, resin more for glass fiber yarn is first extruded by Extruded roller by the yarn infiltrated after resin from glass fiber yarn, then after controlling yarns resins content by tubular die, by the yarn twisted bunchy after plastic squeeze, the yarn of twisted bunchy is required to carry out cutting according to design length, then put into trailing edge mould and shakeout laying, until complete the filling to trailing edge mould, finally wait for that the yarn infiltrating resin is mold curing, the demoulding obtains required trailing edge reinforcement.
As mentioned above, the advantage of this case is as follows:
1, raw material use glass fiber yarn, can fill erose trailing edge mould, can operate in the trailing edge mould that width is narrower.
2, many glass fiber yarns are be arranged in parallel line up sheet export, be convenient to the traction of postorder and neat twisted bunchy, be convenient to shakeout laying.
3, control resin content by plastic squeeze, be convenient to the resin content reaching designing requirement, control the quality stability of trailing edge reinforcement.
4, the yarn twisted bunchy after resin is infiltrated by many, the yarn of twisted bunchy is required to carry out cutting according to design length, then put into trailing edge mould and shakeout laying, until trailing edge mold filling completes, its can the irregular trailing edge mould of suitable shapes filling and make the trailing edge reinforcement of many sizes.
5, because yarn has infiltrated resin and mold curing at trailing edge, so the trailing edge reinforcement that after the demoulding, available can be good, trailing edge can be avoided to occur possibility of fold, the service life of raising blade.
