Abstract
The utility model discloses a die for manufacturing multi-size wind driven generator blades. The die consists of a plurality of sections of dies, wherein different sections of dies are connected with one another through combining devices, so that blades of different sizes can be manufactured. By the die, a blade die is divided into four sections; each section comprises a plurality of options; by changing the sizes of a blade tip die, a blade middle die and a blade root die, the die can be converted from manufacturing of a blade of a certain size into manufacturing of another blade of another size; and furthermore, at the beginning of the manufacturing, the manufacturing of one or two blades of different sizes can be covered, and then blade components of corresponding sizes are added according to a production requirement. The die has the beneficial effects that the die can manufacture multiple blades of various sizes, so that the cost is reduced, the manufacturing space of the die is saved, and the blades are convenient to transport.
Description
Technical field
The utility model relates to and is applied to the blade of wind-driven generator mould manufacturing 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 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 big, and weight is big, 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, the breakage that can't repair as if local appearance in the maintenance process, and entire die all can't re-use.
The utility model content
In order to solve the defective in the above-mentioned technology, the purpose of this utility model provides a kind of many sizes blade production segmented mould, has overcome traditional moulds, and it is single to make product, can't upgrade, and weight is big, transportation inconvenience, the deficiency of serious waste of resources.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of for the mould of making many sizes blade of wind-driven generator, comprise multistage mould and composite set, according to the pre-preparation blade dimensions in blade root, leaf, the blade tip position selects the correspondent section mould respectively for use, is divided into two section dies in the leaf, 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 butt joint of trapezoidal location, trapezoidal location was laid sealing joint strip up and down when adjacent multistage mould butt joint was made up, and the docking location upper surface is reserved one section repair layer.
Carry out the secondary location by trapezoidal alignment pin on the connecting plate.Trapezoidal alignment pin is played a location perforation near upper surface one end, passes a spacing pole during location in positional punch.
Described sealing joint strip is silica gel strip.
The beneficial effect of blade of wind-driven generator mould described in the utility model 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 multiple size 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, mould recycling rate of waterused height, 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 utility model 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 use for back one section, make the aerodynamic configuration that influences blade after the mould change size hardly, blade tip is less to the aerodynamic configuration influence, 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 for use, the close blade aerodynamic configuration of size is basic identical, thereby can select back, blade of the same race middle part terminal mould for use, the different capacity lower blade can use blade tip mould of the same race, and power of the same race changes blade tip mould adjustable size joint blade length separately.
As shown in Figure 4, the utility model is selected suitable blade root portion mould 1 for use according to making the root of blade flange diameter in use, back terminal mould 3 in terminal mould 2 and the leaf before selecting in the leaf according to length of blade is selected the mould of the little leaf tip mould 4 of the pneumatic influential effect of blade being formed required blade dimensions simultaneously for use.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-deck location mechanism, is cut into trapezoidal location pattern during mould frp layer 10 sectional makings in advance, and according to the butt joint of trapezoidal location, trapezoidal location is laid silica gel strip 11 up and down, guarantees the mould sealing property during mould butt joint.The docking location upper surface is reserved one section repair layer 12, repairs after the butt joint, guarantees that die surface is smooth smooth.Carry out secondary location (see figure 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 utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
