Abstract
The invention discloses a die of a blade for an air blower, which consists of a plurality of sections of dies. The different sections of the dies are connected through a combination device, so that blades with different sizes are manufactured. The die divides a blade die into four sections, and each section comprises a plurality of options. By changing the sizes of a blade point die, a blade middle part die and a blade root die, the die can be used for manufacturing the blade with the other size from the manufacturing of the blade with one size. Meanwhile, at the beginning of a die manufacturing process, the manufacturing process of the blades with one or two sizes can be covered, and then blade assemblies with corresponding sizes can be additionally arranged according to the production demands. The die provided by the invention has the beneficial effects that the blades with the multiple sizes can be manufactured by one set of die, so that the cost is reduced; the die manufacturing space can be saved; and the die is convenient to transport.
Description
Technical field
The present invention relates to be applied to wind-driven generator vane die and make the field, is a kind of mould for preparing multiple blade of wind-driven generator.
Background technology
At present, all wind electricity blades all adopt the corresponding a kind of size blade of a kind of mould to produce in the world, if the change blade dimensions just need to be made new mould again, thereby in many sizes leaf production process, it is higher to take the production space, and single factory is difficult to the production that full-scale blade can be satisfied in enough spaces.Simultaneously, along with wind-driven generator to more high-power development, the size of blade is also progressively strengthening, traditional moulds can only be eliminated because not satisfying the needs that have size now, has caused the waste of resource.And the traditional moulds size is large, and weight is large, and for security consideration, countries in the world railway, highway administration department all are conditional to the length that carries cargo, height etc., have caused mould transportation difficulty, strengthen cost of transportation.Safeguard the aspect consideration after using, traditional moulds adopts unitary mould, if the breakage that local appearance can't be repaired in the maintenance process, whole mould all can't re-use.
Summary of the invention
In order to solve the defective in the above-mentioned technology, the purpose of this invention is to provide a kind of many sizes blade production segmented mould, overcome traditional moulds, it is single to make product, can't upgrade, and weight is large, transportation inconvenience, the deficiency of serious waste of resources.
The objective of the invention is to be achieved through the following technical solutions:
A kind of many sizes fan blade production segmented mould comprises multistage mould and composite set, according to pre-prepared blade dimensions blade root, in the leaf, the correspondent section mould is selected respectively in the blade tip position, is divided into two section dies in the leaf, and different section dies connect by composite set.
It is to combine by two connecting plates that are welded on the supporting steel frame that composite set connects adjacent multistage mould, wherein locks by fastening bolt between two connecting plates.According to the docking of trapezoidal location, the sealed silicon adhesive tape is laid up and down in trapezoidal location during adjacent multistage mould docking combination, and the docking location upper surface is reserved one section repair layer.
Carry out the secondary location by trapezoidal pin on the connecting plate.Trapezoidal pin is played a location perforation near upper surface one end, passes a spacing pole during location in positional punch.
The sealed silicon adhesive tape is replaceable when the mould serviceability temperature is not high to be the conventional seals adhesive tape.
The beneficial effect of wind-driven generator vane die of the present invention is: utilize present technique to substitute the mould that can only make the single kind blade originally, mould is changed to assembly from integral body, can make the sizes blade with a mold, simultaneously, be convenient to transportation after the mold sections, reduced cost of transportation, made at wind field field fabrication blade, this theory of on-the-spot installation is easier to implement.Simultaneously, present technique can be upgraded to mould, changes the local segmentation mould, both can satisfy the requirement of new size blade, the mould recycling rate of waterused is high, the maintenance of single hop mould, also convenient than unitary mould with the damage replacing, more be conducive to product promotion.

The specific embodiment
Below in conjunction with accompanying drawing and instantiation the present invention is elaborated.
As shown in Figure 4, a whole set of mould is divided into multistage, when needing to make the blade of a certain size, by changing certain section die or a few section die, makes it meet the blade dimensions requirement.Single certain section die can be reused when making many sizes blade.Wherein, blade root is divided into a plurality of models according to connecting hub size, the corresponding corresponding wheel hub adpting flange size of difference, be divided into two sections in the leaf, guarantee blade root smooth transition in the leaf the last period, select different moulds for rear one section, make the aerodynamic configuration that affects hardly blade after the mould change size, blade tip is less on the aerodynamic configuration impact, makes the length of blade and mainly finishes by the change tip segment.Connect basic identical with power different size root of blade, thereby select terminal mould before root of blade of the same race and the blade middle part, the close blade aerodynamic configuration of size is basic identical, thereby can select terminal mould behind the blade of the same race middle part, the different capacity lower blade can use blade tip mould of the same race, and power of the same race changes separately blade tip mould size adjustable vane length.
As shown in Figure 4, the present invention selects suitable blade root mould 1 according to making the root of blade flange diameter in use, rear terminal mould 3 in terminal mould 2 and the leaf before selecting in the leaf according to length of blade is selected the mould that the little leaf tip mould 4 of the pneumatic influential effect of blade is formed required blade dimensions simultaneously.Between adjacent two section dies, use composite set to connect, as shown in Figure 1.
Shown in Fig. 2,3, be welded to connect on the adjacent two section die supporting steel frames 6 between plate 5, two connecting plates 5 by fastening bolt 7 lockings.Location between adjacent multistage mould utilizes double orientation mechanism, is cut in advance trapezoidal location pattern during mould glass steel layer 10 sectional making, and according to the docking of trapezoidal location, silica gel strip 11 is laid up and down in trapezoidal location, guarantees the mould sealing property during mould docking.The docking location upper surface is reserved one section repair layer 12, repairs after the docking, guarantees that die surface is smooth smooth.Carry out secondary location (seeing Fig. 5) by trapezoidal alignment pin 8 on the connecting plate 5, trapezoidal alignment pin 8 front ends are reserved a circular port, the trapezoidal alignment pin 8 of every section die link position draws a straight line, pass each trapezoidal alignment pin 8 front end circular hole with spacing pole 9, and pass on the connecting plate 5 two ends limited blocks 13, play fastening and positioning action to trapezoidal alignment pin 8 on the one hand, on the other hand can also the detection and location degree of accuracy.
Present stage, the blade mold segmentation limit was in the 2-4 section, and according to the developer blade direction, a day rear blade constantly lengthens, and do not get rid of mould and was divided into 5 sections, 6 sections even more how may.Therefore, above-described embodiment, the present invention specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacing all should be included in protection scope of the present invention.
