In order to effectively prevent the second shutter 11 from rotating inward (i.e., rotating inward) of the burring shutter 13 or being installed beyond the first shutter 10, a stopper may be provided on the burring shutter 13 to ensure that the second shutter 11 is coplanar with the inner surface of the first shutter 10, wherein the inner surface referred to herein refers to the surfaces of the burring shutters 13 (including the second shutter 11 and the first shutter 10) respectively located at both sides facing each other. Here, the inner side of the burring baffles 13 refers to the side of the burring baffles 13 located at both sides, respectively, facing each other.

Referring to fig. 4, according to an example, the stopper portion may be provided as a protrusion plate 31 protruding upward from an inner side portion of the upper end, and the second shutter 11 is formed with a recess 30 corresponding to the protrusion plate 31. When the second baffle 11 rotates inwards, the corresponding convex plate 31 and the concave part 30 can cooperate to ensure that the second baffle 11 is coplanar with the inner surface of the first baffle 10, thereby ensuring that the appearance of the blade web flanging meets the production requirements.

In order to prevent the second baffle 11 from being turned outwards during the web manufacturing operation performed by the operator, a locking member may be disposed on the flanging baffle 13 to ensure that the second baffle 11 is coplanar with the outer surface of the first baffle 10, where the outer surface refers to the surface of the flanging baffles 13 respectively located at the two sides, which is opposite to the inner surface.

According to one example, the locking member may be provided as a latch structure. The locking member may include: a hole 41 provided on an outer surface of one of the first shutter 10 and the second shutter 11; a guide rail 45 provided on an outer surface of the other of the first shutter 10 and the second shutter 11 in correspondence with the hole 41; the pin 40, which moves on the guide rail 45, can be inserted into the hole 41 and withdrawn from the hole 41 to lock the second shutter 11 to the first shutter 10 or unlock from the first shutter 10.

According to another example, the locking member may comprise: magnets respectively disposed on outer surfaces of the first barrier 10 and the second barrier 11; and a magnetic plate which is adsorbed on the outer surfaces of the first barrier 10 and the second barrier 11 by the magnetic force of the magnet, thereby locking the second barrier 11 to the first barrier 10. Also, the magnetic plate may be removed from the outer surfaces of the first shutter 10 and the second shutter 11 by applying an external force, thereby unlocking the second shutter 11 from the first shutter 10. If one end of the magnetic plate is pivotally fixed to the outer surface of one of the first shutter 10 and the second shutter 11, the second shutter 11 can be unlocked from the first shutter 10 by rotating the magnetic plate down from the outer surface of the other of the first shutter 10 and the second shutter 11 by applying an external force.

The structure of the locking member described above is merely an example, and the present invention is not limited to this, and other structures that can lock the second shutter 11 and the first shutter 10 may be possible.

In order to ensure that the profile of the web flanging meets the production requirements, the second baffle plate 11 may be preferably a plurality of baffle plates connected end to end along the length direction of the web forming part, so that the combined second baffle plate 11 is curved as a whole.

In order to make the transition between the second baffles 11 smooth and facilitate the positioning and installation, the head-to-tail contact surfaces of two adjacent second baffles 11 are in complementary L shapes when viewed from top to bottom (i.e. from the top view). However, the embodiment of the present invention is not limited to this, and the head-to-tail contact surfaces of two adjacent second baffles 11 may also have other complementary shapes, as long as it can ensure that the combined inner surfaces of two adjacent second baffles 11 are coplanar.

In addition, in order to further ensure that the combined inner surfaces of two adjacent second baffle plates 11 are coplanar, a bolt structure can be installed along the length direction of the web forming part to fix the two adjacent second baffle plates 11.

A method for manufacturing a wind turbine blade web according to an exemplary embodiment of the invention will be described in detail below with reference to fig. 8 to 11.

The method for manufacturing the wind generating set blade web plate can comprise the following steps: the second shutter 11 of the burring shutter 13 of the above mold is rotated or mounted to be coplanar with the first shutter 10 (step S1). The web molding material is laid on the die face plate 12 and the burring baffle 13 (step S2). And (8) performing vacuum infusion and curing molding to obtain a web molded part (step S3). The second shutter 11 is turned or removed to expose a portion of the web molding to be cut (step S4). Cutting is performed on the portion of the web profile to be cut to obtain the blade web (step S5).

In the following, the method of manufacturing a wind turbine blade web will be further described, taking as an example a mould in which the second shutter 11 is pivotally mounted to the first shutter 10.

The manufacturing method comprises the steps of firstly cleaning a mould for manufacturing the wind generating set blade web, and coating a release agent on the mould to facilitate demoulding.

Next, the second flap 11 of the mould flanging flap 13 for manufacturing the wind turbine blade web is turned to be coplanar with the first flap 10 and the second flap 11 is locked to the first flap 10 by means of a locking piece.

Next, a rough surface film 21 is laid on the first baffle 10 and the second baffle 11 of the burring baffle 13 to form a rough surface on the burring of the web molding obtained in the future, thereby increasing the adhesive force between the burring and the blade shell. The rough surface film 21 may be laid such that one end thereof is located on the mold face 12 inside the burring baffle 13 and the other end thereof exceeds the upper end of the second baffle 11 and is located on the outer surface of the second baffle 11. A film or a cloth layer having a surface roughness may be used as the rough surface film 21, and for example, a release cloth may be used as the rough surface film 21.

Next, a first cloth layer 20 is laid on the die face plate 12 and the turn-up fence 13 inside the turn-up fence 13, and the first cloth layer 20 may be laid on the turn-up fence 13 beyond the upper end of the first fence 10 so as to form a portion of the web turn-up to be cut. For example, the first fabric layer 20 may be a glass cloth. The number of layers of the glass cloth may be multiple layers, for example, 2 to 4 layers, however, embodiments of the present invention are not limited thereto, and the number of layers of the glass cloth may be reasonably changed according to the design requirements of the web product.

Next, the core 22 is laid on the first fabric layer 20, and the core 22 may be laid only on the mold face plate 12 located inside the turnup flaps 13. The core material 22 is a rigid and lightweight material, which can be used for filling, supporting, shaping and providing rigidity. For example, the core material 22 may be a PVC core material, however, the embodiment of the present invention is not limited thereto, and the core material 22 may also be a PET material or a wood material, etc., as long as it can play a role of filling support, shaping, and providing rigidity.

Next, a second cloth layer 20' is laid on the core 22. Here, the material of the second fabric layer 20' may be the same as that of the first fabric layer 20, and a description thereof will not be repeated. In addition, the number of layers of the glass cloth may be multiple layers, for example, 2 to 4 layers, however, embodiments of the present invention are not limited thereto, and the number of layers of the glass cloth may be reasonably changed according to the design requirements of the web product. And finishing the laying of the web molding material.

Then, after the web forming material is laid, the portion of the rough surface film 21 exceeding the upper end of the second baffle 11 is turned back to the inside of the burring baffle 13 to cover a portion of the web forming material (see fig. 10), thereby avoiding a problem that the second baffle 11 is wrapped therein and cannot be rotated after the vacuum infusion machine cures and forms.

And then, laying a vacuum infusion auxiliary material on the web forming material. An auxiliary injection layer 23, a rubber guide tube 25 and a vacuum film 24 may be sequentially laid on the second cloth layer 20', wherein the auxiliary injection layer 23 includes a release fabric, an isolation film and a flow guide net which are sequentially laid, and both ends of the vacuum film 24 are respectively located at the outer sides of the turn-up baffles 13, and both ends of the vacuum film 24 are respectively sealed on the mold panels 12 located at the outer sides of the turn-up baffles 13 by using a sealing tape 26 to perform vacuum pumping, so as to establish a vacuum system.

And (3) pouring resin into the web forming material by adopting a vacuum pouring method, heating and curing, and removing the vacuum pouring auxiliary material to obtain the web forming material.

Next, the second flap 11 is turned down to expose the portion of the web profile to be cut. The cutting of the portion to be cut is performed using a cutter 51. During cutting, the cutting machine 51 moves slowly at a constant speed along the first baffle 10 of the flanging baffle 13 to ensure the cutting quality.

Referring to fig. 11, in order to ensure the cutting quality of the web flange, reduce the contact between the cutter 51 and the flange guard 13, and prevent safety accidents, the cutter 51 may be mounted on a bracket 53 located on the outer side of the flange guard 13. When the cutter 51 has the blade 52 that performs cutting, the front end of the blade 52 may be extended by about 1cm beyond the inner surface of the web flange 50. The cutter 51 may be fixedly mounted on the bracket 53, or may be detachably mounted on the bracket 53 by means of a clip or a bolt, etc., to facilitate removal and maintenance.

To facilitate controlled movement, the bottom of the carriage 53 may also be fitted with rollers or rails that enable the carriage 53 to move. Further, on the basis of setting up the track, motor and controller can also be add to control support 53 moves along the track, in order to realize automated control, improve cutting accuracy and save the manpower, thereby improve product quality and improve production efficiency.

Preferably, the cutting may be performed using a laser cutting machine to reduce dust generated during cutting using a cutter such as the saw blade 52, thereby achieving dust-free cutting and preventing the dust from causing damage to the environment and workers.

And then, demolding the web plates by using a traveling crane, directly turning the web plates to a vertical state to put the pair of assembly supports, carrying out pair assembly connection on the two web plates, and storing the two web plates on the pair of assembly supports for later use.
