Technical Field

[0002] This application belongs to the field of wind power technology, and particularly relates to a web assembly tooling and a blade molding method. Background Art

[0003] With the continuous development of wind power technology, it has been a development trend in the industry to provide larger power wind turbine generators with stable operation. On the one hand, the blades of high-power wind turbine generators will become longer and longer. The wind turbine blade mainly consists of a shell and a web. The shell is composed of two half-shells, namely the windward shell and the leeward shell. The hollow space between the two half-shells is supported by the web in the extending direction of the blade.

[0004] In the manufacture of blades, it is usually necessary to use a web assembly tooling to set the web on the blade shell. However, as the blade size gradually increases, the size of the web assembly tooling also gradually increases, resulting in a relatively large floor area of the web assembly tooling. Further, due to the unreasonable structure of the existing web assembly tooling, the web cannot be assembled on the blade shell safely and accurately. Summary of the Invention

[0010] In some embodiments of the present application, the clamping frame includes an open state and a locked state. In the open state, the gap between the second positioning member and the first positioning member is greater than the web assembly spacing. In the locked state, the gap between the second positioning member and the first positioning member is less than or equal to the thickness of the body of the web. The supporting assembly can move along the extending direction of the first bracket to adjust the gap between the second positioning member and the first positioning member.

[0011] In some embodiments of the present application, the connecting frame assembly further includes two connecting arm mechanisms provided at both ends of the first bracket. The connecting arm mechanism can be switched between an unfolded state and a stored state. In the unfolded state, the lifting assembly and the supporting assembly are disposed between the two connecting arm mechanisms.

[0012] In some embodiments of the present application, the connecting arm mechanism includes a mating portion provided at one end of the connecting arm mechanism. The mating portion can cooperate with the blade housing forming die to limit the single-piece pressurizing tooling.

[0013] In some embodiments of the present application, the single-piece pressurizing tooling further includes two lifting arms and a hook structure mounted on the lifting arms. The lifting arms are provided on the first bracket, and the two lifting arms are symmetric about the rotating frame. The hook structure is in wedge fit with an external lifting assembly.

At the same time, multiple pressurizing tooling units can work simultaneously, improving the blade forming efficiency. After the web assembly is completed, the pressurizing tooling units can be stored separately. Compared with the traditional structure in which the pressurizing tooling is made into a whole, the pressurizing tooling units provided by the embodiments of the present invention can effectively save space.

[0036] For a better understanding of the present invention, the following Figures 1 to 8 will describe in detail the pressurizing tooling unit 100, the web assembly tooling, the blade forming method, and the blade 400 provided by the embodiments of the present invention.

[0037] Please refer to Figures 1 to 6 , Figure 1 which shows a perspective view of the pressurizing tooling unit provided by an embodiment of the present invention, Figure 2 which shows a front view of the pressurizing tooling unit provided by an embodiment of the present invention, Figure 3 which shows a schematic structural view of the lifting assembly provided by an embodiment of the present invention, Figure 4 which shows a schematic structural view of the downward pressing assembly provided by an embodiment of the present invention, Figure 5 which shows a schematic overall structural view of the web assembly tooling and the web assembly provided by an embodiment of the present invention, Figure 6 which shows a schematic structural view of the pressurizing tooling unit and the outer shell forming die assembly provided by an embodiment of the present invention.

[0038] An embodiment of the present invention provides a single pressurizing tooling 100, which includes a connecting frame assembly 10, a lifting assembly 20, and a supporting assembly 30. The connecting frame assembly 10 includes a first bracket 11. The lifting assembly 20 is rotatably arranged on the first bracket 11. The lifting assembly 20 includes a rotating frame 21, a lifting member 22 and a first positioning member group 23 arranged on the rotating frame 21. The lifting member 22 is used to cooperate with the web 450 to lift the web 450. The extending direction of the rotating frame 21 intersects with the extending direction of the first bracket 11. The first positioning member group 23 includes a plurality of first positioning members 231 arranged at intervals along the extending direction of the rotating frame 21. The supporting assembly 30 is movably arranged on the first bracket 11. The supporting assembly 30 includes a clamping frame 31 and a plurality of second positioning members 32 arranged on the clamping frame 31. At least part of the second positioning members 32 are arranged opposite to the first positioning members 231. There is a gap between the second positioning members 32 and the first positioning members 231 for accommodating the web 450.

[0039] Wherein, the supporting assembly 30 can move along the extending direction of the first bracket 11 to adjust the gap between the second positioning member 32 and the first positioning member 231, so that the second positioning member 32 and the first positioning member 231 can better clamp the web 450 and better limit the chordal Y position of the web 450 on the housing 303 to be assembled. In some embodiments, the second positioning members 32 and the first positioning members 231 are arranged in one-to-one correspondence and opposite to each other.

[0040] For the single pressurizing tooling 100 provided by the embodiment of the present invention, the single pressurizing tooling 100 includes a connecting frame assembly 10, a lifting assembly 20 and a supporting assembly 30. The lifting member 22 in the lifting assembly 20 can cooperate with the web 450 to lift the web 450, which is convenient for lifting the web 450 and transferring it to the housing 303 to be assembled. Further, the supporting assembly 30 provided by the embodiment of the present invention can move to prevent damage to the web 450, so that the web 450 can be safely and accurately connected to the housing. At the same time, since the single pressurizing tooling 100 occupies a small area, it can be stored separately to save space.

[0041] In some embodiments, the clamping frame 31 includes an open state and a locked state. In the open state, the gap between the second positioning member and the first positioning member is greater than the assembly spacing of the web 450. Optionally, the assembly spacing of the web 150 is greater than or equal to twice the thickness of the web 450. In the locked state, the gap between the second positioning member and the first positioning member is less than or equal to the thickness of the body 451 of the web 450. Through the above settings, it is possible to prevent the single-piece pressing tool 100 from bumping against the web 450, resulting in deformation or bonding defects of the web 450. During the hoisting of the single-piece pressing tool 100 and the installation of the web 450, the clamping frame 31 is in the locked state. At this time, the gap between the second positioning member and the first positioning member is equal to the assembly spacing of the web 450, ensuring accurate positioning data of the web 450.

[0042] Please refer to Figures 1 to 3 , in some embodiments, the included angle between the extending direction of the rotating frame 21 and the extending direction of the first bracket 11 is 90 degrees. The rotating frame 21 rotates around its own axis. The rotating frame 21 can drive the lifting member 22 and the first positioning member group 23 to rotate synchronously to lift and release the web 450. The extending direction of the lifting member 22 is the same as the extending direction of the first positioning member group 23, facilitating the lifting member 22 and the first positioning member group 23 to approach or move away from the web 450 simultaneously.

[0043] To improve the strength of the rotating frame 21, optionally, the rotating frame 21 can include square steel. At this time, the rotation axis of the rotating frame 21 is the center line of the square steel. In specific implementation, to realize the rotation of the rotating frame 21, the rotating frame 21 can be connected to a rotation driving member, for example, connecting the rotating frame 21 to the rotating shaft of a generator.

[0044] Please refer to Figure 6 , in some embodiments, the web 450 includes a body 451 and connecting flanges 452. The connecting flanges 452 are arranged at both ends of the body 451 and are used to connect with the blade housing. In specific implementation, when the web 450 needs to be lifted, the web 450 is placed in the single-piece pressing tool 100, and the rotating frame 21 is rotated so that the lifting member 22 abuts against the inner surface of the connecting flange 452. At this time, multiple first positioning members 231 in the first positioning member group 23 contact the surfaces of the body 451 along the thickness direction to support the web 450. When the web 450 needs to be released, the rotating frame 21 is rotated again. For example, the rotating frame 21 is rotated 90 degrees. At this time, the lifting member 22 and the connecting flange 452 are misaligned with each other, and the first positioning member 231 also has no contact with the body 451 of the web 450, facilitating the installation of the web 450 on the blade housing.

[0045] Please further refer to Figure 2 and Figure 4, in some embodiments, the lifting member 22 is disposed on a side of the first positioning member group 23 close to the first bracket 11. The pressurizing tooling unit 100 further includes a pressing-down assembly 40. The pressing-down assembly 40 is disposed on the first bracket 11 and located between the first bracket 11 and the lifting member 22. The pressing-down assembly 40 includes a pressing-down block 41 which is telescopically arranged to bond the web 450 to the blade housing. Since the web 450 is usually fixedly arranged on the blade housing through an adhesive 470, by arranging the pressing-down assembly 40 to press down the web 450, it is convenient for the web 450 to be firmly connected to the blade housing. At the same time, by arranging the pressing-down assembly 40, the thickness of the adhesive 470 layer between the web 450 and the blade housing can be adjusted, improving the forming quality of the blade 400.

[0046] In specific implementation, the pressing-down assembly 40 may further include a driving member. The driving member includes a telescopic rod which is connected to the pressing-down block 41 to achieve the telescopic arrangement of the pressing-down block 41. Optionally, the driving member can be a cylinder or an electric cylinder.

[0047] In order to better press down the web 450, in some embodiments, when the web 450 includes a connecting flange 452 for connecting to the blade housing, the pressing-down block 41 includes a pressing-down portion. The shape of the contact surface between the pressing-down portion and the connecting flange 452 is matched. Optionally, the pressing-down portion is parallel to the connecting flange 452. At this time, the angle between the pressing-down block 41 and the connecting flange 452 of the web 450 remains the same. Through the above arrangement, when the pressing-down portion presses down the web 450, the contact surface between the pressing-down portion and the connecting flange 452 of the web 450 is increased. It can be understood that in order to keep the angle of the pressing-down block 41 of the pressing-down assembly 40 stable and ensure the distance in the width direction N between the web 450 and the housing 303 to be assembled, when the pressing-down assembly 40 is used for the first time, the position of the pressing-down block 41 can be adjusted. When the distance between the web 450 and the inner surface of the housing 303 to be assembled is ensured to be a preset distance, the pressing-down block 41 can be welded to the pressing-down assembly 40 by an electric welding machine to prevent the position of the pressing-down block 41 from shifting during use. Optionally, the preset distance can be set according to the user's requirements.

[0048] It can be understood that the pressurizing tooling unit 100 can be used to connect a single web 450 to the housing 303 to be assembled, or the pressurizing tooling unit 100 can be used to connect the paired webs 450 to the housing 303 to be assembled simultaneously to improve the forming efficiency of the blade 400.

[0049] In order to lift the paired webs 450 simultaneously and connect them to the housing 303 to be assembled, in some embodiments, the number of the first positioning member groups 23 is two, and the two first positioning member groups 23 are respectively arranged on both sides of the rotary frame 21; and / or, the number of the support assemblies 30 is two, and the two support assemblies 30 are arranged oppositely and symmetric about the rotary frame 21; the second positioning members 32 correspond to the first positioning members 231 one by one to form a gap.

[0050] Optionally, in order to safely and accurately connect the paired webs 450, the number of the first positioning member groups 23 and the number of the support assemblies 30 are both two. The two first positioning member groups 23 are arranged between the two support assemblies 30, so that the first positioning member groups 23 and the support assemblies 30 jointly support the web 450, and further accurately limit the chordal Y position of the web 450 on the housing 303 to be assembled.

[0051] In specific implementation, since the second positioning members 32 correspond to the first positioning members 231 one by one to form a gap, the web 450 can be received in the gap, so that the second positioning members 32 and the first positioning members 231 cooperate with each other to jointly position the web 450, preventing the web 450 from tilting during the processes of assembly, hoisting, etc. At the same time, since the second positioning members 32 and the first positioning members 231 can generate a clamping force on the web 450, by corresponding the second positioning members 32 to the first positioning members 231 one by one, the force on the web 450 is made uniform, preventing stress damage to the web 450.

[0052] Please further refer to Figure 3 , in some embodiments, the lifting assembly 20 further includes an adjusting member 24, and the adjusting member 24 is arranged between the first positioning member 231 and the rotary frame 21. The adjusting member 24 can adjust the distance between the first positioning member 231 and the rotary frame 21. By arranging the adjusting member 24 in the lifting assembly 20, the adjusting member 24 can rotate simultaneously with the lifting assembly 20, so that when the lifting assembly 20 lifts the web 450, the first positioning member 231 can always support on the surface of the web body 451 of the web 450, preventing the web 450 from deforming. Optionally, the adjusting member 24 includes a reverse nut, and the distance between the first positioning member 231 and the rotary frame 21 can be finely adjusted.

[0053] Optionally, the first positioning member 231 includes a first roller 2311. The axis of the first roller 2311 is parallel to the rotation axis of the rotating frame 21. The constituent material of the first roller 2311 includes polyurethane. With the above arrangement, when the lifting assembly 20 needs to lift the web 450, the first roller 2311 can contact the inner surface of the body 451 of the web 450. Thus, when the rotating frame 21 drives the first roller 2311 to rotate, the first roller 2311 can rotate along the surface of the web 450, preventing damage to the web 450. Further, by reasonably setting the material of the first roller 2311, the wear resistance of the first roller 2311 can be increased, and the damage to the web 450 caused by the rolling of the first roller 2311 along the surface of the web 450 can be further reduced, thereby improving the reliability of the single pressing tool 100.

[0054] In order to further accurately position the chordal Y position of the web 450 on the blade housing, the second positioning member 32 includes a second roller 321. The axis of the second roller 321 intersects the rotation axis of the rotating frame 21. The constituent material of the second roller 321 includes polyurethane. Optionally, the angle between the axis of the second roller 321 and the rotation axis of the rotating frame 21 is 90 degrees. By reasonably setting the angle between the second roller 321 and the rotating frame 21, the second roller 321 and the first roller 2311 can better clamp the web 450, so that the web 450 can be accurately installed on the housing 303 to be assembled.

[0055] In some embodiments, the support assembly 30 further includes a screw assembly. The screw assembly connects the second positioning member 32 to the clamping frame 31. By providing the screw assembly, the distance between the second positioning member 32 and the clamping frame 31 can be adjusted, thereby ensuring accurate positioning data of the web 450 and preventing shrinkage deformation of the web 450.

[0056] In some embodiments, the connecting frame assembly 10 further includes two connecting arm mechanisms 12 provided at both ends of the first bracket 11. The connecting arm mechanisms 12 can be switched between an unfolded state and a retracted state. In the unfolded state, the lifting assembly 20 and the support assembly 30 are provided between the two connecting arm mechanisms 12. At this time, the connecting frame assembly 10 forms a gantry frame structure straddling the top and both sides of the web 450. Optionally, the connecting arm mechanism 12 and the first bracket 11 are connected by a rotating shaft pin, so that the connecting arm mechanism 12 can realize the functions of folding and unfolding, saving floor space.

[0057] Through the above settings, the connecting arm mechanism 12 can be set according to the user's needs. When it is necessary to use the pressurizing tooling unit 100 to install the web 450, the two connecting arm mechanisms 12 are opened. After the pressurizing tooling unit 100 is used, the connecting arm mechanism 12 can be in a stored state to further reduce the occupied space of the pressurizing tooling unit 100. To achieve the accurate connection between the web 450 and the housing 303 to be assembled, the housing 303 to be assembled, the web 450, and the pressurizing tooling unit 100 are generally formed as a whole and connected to the blade housing forming die 300. The pressurizing tooling unit 100 and the housing forming die 300 cooperate with each other to achieve the accurate installation of the web 450 and the housing 303 to be assembled.

[0058] Please refer further to Figure 6 To improve the installation quality of the web 450, in some embodiments, the connecting arm mechanism 12 includes a mating portion 121. The mating portion 121 is provided at one end of the connecting arm mechanism 12. The mating portion 121 can cooperate with the blade housing forming die 300 to limit the pressurizing tooling unit 100.

[0059] Optionally, the blade housing forming die 300 includes a cavity and a base 301. The cavity is used to form the housing 303 to be assembled. The base 301 includes a first positioning portion 302. The first positioning portion 302 matches the mating portion 121. Optionally, the first positioning portion 302 can be one of a positioning block or a positioning hole, and the mating portion 121 can be the other. The accurate positioning of the pressurizing tooling unit 100 and the blade housing forming die 300 is achieved through the cooperation between the first positioning portion 302 and the mating portion 121, and then the accurate positioning of the web 450 and the housing 303 to be assembled is achieved. It can be understood that the mating portions 121 on the two connecting arm mechanisms 12 can have the same structure. Of course, the sizes of the two mating portions 121 can also be different to facilitate alleviating the situation where the pressurizing tooling unit 100 and the blade housing forming die 300 are stuck during positioning due to machining errors.

[0060] During the assembly process of the web 450 and the housing 303 to be assembled, the web 450 needs to be lifted. In some embodiments, the pressurizing tooling unit 100 further includes a lifting arm 50. The lifting arm 50 is provided on the first bracket 11. Optionally, the number of the lifting arms 50 can be two. The two lifting arms 50 are symmetric about the rotating frame 21 to make the structure of the pressurizing tooling unit 100 more reasonable. The lifting arm 50 includes a hook structure to cooperate with an external lifting assembly to lift, transfer, and install the pressurizing tooling unit 100 and the web 450.

[0061] In summary, the single pressurizing tool 100 provided by the embodiment of the present invention includes a connecting frame assembly 10, a lifting assembly 20, and a supporting assembly 30. The lifting assembly 20 includes a rotating frame 21, a lifting member 22, and a first positioning member group 23 disposed on the rotating frame 21. The lifting member 22 and the first positioning member group 23 are rotatably disposed on the first bracket 11 through the rotating frame 21. When the lifting member 22 rotates to a reasonable position, it can cooperate with the web 450 to lift the web 450, facilitating the lifting and transfer of the web 450 onto the blade housing. Further, the supporting assembly 30 includes a second positioning member 32. At least a part of the second positioning member 32 is disposed opposite to the first positioning member 231 with a gap therebetween. The web 450 can be placed in the gap, such that the gap can position the chordal Y position of the web 450 on the housing. Moreover, since the supporting assembly 30 is movably disposed on the first bracket 11, the gap between the second positioning member 32 and the first positioning member 231 can be adjusted according to actual requirements. For example, when connecting the web 450 to the single pressurizing tool 100, the gap between the second positioning member 32 and the first positioning member 231 is increased by moving the supporting assembly 30, facilitating the placement of the web 450 in the gap and reducing damage to the web 450. When the web 450 is placed in the gap, the supporting assembly 30 is moved to make the second positioning member 32 abut against the surface of the web 450, such that the second positioning member 32 and the first positioning member 231 jointly clamp the web 450 to better limit the position of the web 450, and further enabling the web 450 to be safely and accurately connected to the blade housing.

[0062] Further, since the single pressurizing tool 100 occupies a small area, it can be stored separately to save space. When the single pressurizing tool 100 is applied to the web assembly tool, by connecting the single pressurizing tool 100 to the tool bracket 201, multiple single pressurizing tools 100 can cooperate with each other to limit the chordal Y position of the web 450 on the housing 303 to be assembled. At the same time, multiple single pressurizing tools 100 can work simultaneously, improving the forming efficiency of the blade 400. After the assembly of the web 450 is completed, the single pressurizing tool 100 can be stored separately. Compared with the traditional structure in which the pressurizing tool is made into an integral whole, the single pressurizing tool 100 provided by the embodiment of the present invention can effectively save space.

[0063] Please further refer to Figure 5 , the embodiment of the present invention further provides a web assembly tool, including the single pressurizing tool 100 according to any one of the above embodiments and a tool bracket 201. The tool bracket 201 is used to fix each single pressurizing tool 100. The tool bracket 201 can make the projections of each single pressurizing tool 100 coincide along the extension direction of the tool bracket 201. Among them, the extension direction of the tool bracket 201 and the attachment Figure 5The extending direction of the middle web 450 is parallel. Through the above settings, the tooling bracket 201 can limit the positions between multiple pressurizing tooling units 100, and further enable the pressurizing tooling units 100 to limit the positions of the web 450 in the entire long axis direction.

[0064] In some embodiments, the web assembly tooling further includes a web bracket 202 for supporting the web 450. In order to further save the occupied space of the web assembly tooling, the tooling bracket

[0065] 201 is arranged outside the web bracket 202, so that when the pressurizing tooling unit 100 is assembled on the tooling bracket 201, it can be assembled and cooperated with the web 450 arranged on the web bracket 202, avoiding multiple transfers of the pressurizing tooling unit 100. After the tooling bracket 201 assembles multiple pressurizing tooling units 100, the multiple pressurizing tooling units 100 can be respectively connected to the web 450 through the lifting assembly 20, and then the hooks on the lifting arms 50 of all the pressurizing tooling units 100 are hung on the cross beams of the corresponding lifting assemblies 500 in sequence, so as to realize the overall lifting of the web 450 and the multiple pressurizing tooling units 100. Optionally, the matching position between the lifting arm 50 and the lifting assembly 500 can adopt a wedge-shaped fit to realize the stable connection between the lifting arm 50 and the lifting assembly 500.

[0066] Since the web assembly tooling provided by the embodiments of the present invention includes the processing tooling units of any of the above embodiments, therefore, the web 450 can be connected to the housing 303 to be assembled more safely and accurately, and the occupied space of the web assembly tooling is reduced, which is convenient for popularization and application.

[0067] Please refer to Figure 7 , the embodiments of the present invention further provide a blade forming method. By using the above-mentioned pressurizing tooling unit 100 or the web assembly tooling of any of the above embodiments, the blade forming method provided by the embodiments of the present invention includes the following steps:

[0068] S110. Form a housing 303 to be assembled in the blade outer shell forming die 300, and the housing 303 to be assembled is one of the windward side housing 410 and the leeward side housing 420 of the blade 400;

[0069] S120. Connect the web 450 with each pressurizing tooling unit 100 arranged on the tooling bracket 201 by using the lifting assembly 20;

[0070] S130. Arrange the second positioning member 32 close to the web 450, and clamp the web 450 with the first positioning member 231;

[0071] S140. Align and connect the web 450 and the single-piece pressurizing tooling 100 with the outer shell forming die 300 so that the web 450 is connected to the shell 303 to be assembled.

[0072] S150. Assemble the other one of the windward shell 410 and the leeward shell 420 with the shell 303 to be assembled to obtain the blade 400.

[0073] The blade forming method provided by the embodiment of the present invention includes using the single-piece pressurizing tooling 100 in any of the above embodiments to install the web 450 on the shell 303 to be assembled, so that the web 450 can be installed on the shell 303 to be assembled quickly, safely and accurately, improving the forming efficiency of the blade 400 and the quality of the blade 400, and facilitating popularization and application. It should be noted that the web 450 can be installed on the shell 303 to be assembled individually, or the paired webs 450 to be installed can be installed on the shell 303 to be assembled together. The installation method of a single web 450 to be installed is similar to the method of installing the paired webs 450 to be installed together. In this article, the example of installing the paired webs 450 to be installed on the shell 303 to be assembled together is used for illustration.

[0074] In step S110, forming the shell 303 to be assembled in the blade outer shell forming die 300 may include placing the main beam in the blade outer shell forming die 300, and then laying the skin on the main beam to form the shell 303 to be assembled. In specific implementation, the blade outer shell forming die 300 includes a windward shell forming die and a leeward shell forming die. When the shell 303 to be assembled is the windward shell 410, the main beam can be placed in the windward shell forming die, and then the skin is laid on the main beam to form the windward shell 410. Optionally, when the shell 303 to be assembled is the leeward shell 420, the main beam can be placed in the leeward shell forming die, and then the skin is laid on the main beam to form the leeward shell 420. It can be understood that the position of the main beam in the windward shell 410 or the leeward shell 420 can be positioned by the positioning device, so that the position of the main beam in the shell 303 to be assembled is accurate, thereby improving the structural accuracy of the shell 303 to be assembled and facilitating the accurate assembly of the shell 303 to be assembled with the web 450.

[0075] In some embodiments, in step S120, connecting the web 450 with each single-piece pressurizing tooling 100 arranged on the tooling support 201 by using the lifting assembly 20 includes: rotating the lifting assembly 20 until the lifting member 22 contacts the connecting flange 452 of the web 450, and at the same time, the first positioning member 231 abuts against the surface in the thickness direction of the web 450.

[0076] Specifically, in step S120, multiple individual pressurizing tooling units 100 placed separately can be first connected to the tooling support 201 so that the individual pressurizing tooling units 100 can accurately position the web 450. Then, the rotating frames 21 in the multiple individual pressurizing tooling units 100 are rotated simultaneously, such that the lifting members 22 connected to the rotating frames 21 are respectively connected to the connecting flanges 452 of two paired webs 450. At this time, the first positioning member 231 abuts against the surface of the main body 451 of the web 450 to support and position the web 450. Optionally, the rotating systems in the multiple individual pressurizing tooling units 100 are connected in series, such that the multiple rotating frames 21 can rotate simultaneously to drive the multiple lifting members 22 and the first positioning member 231 to be connected to the web 450. It can be understood that the multiple individual pressurizing tooling units 100 are arranged at intervals along the long axis direction of the web 450, and can lift and position the entire web 450.

[0077] In some embodiments, in step S120, after connecting the web 450 to each individual pressurizing tooling unit 100 disposed on the tooling support 201 by using the lifting assembly 20, the blade forming method further includes: disposing the second positioning member 32 away from the first positioning member 231 such that the distance between the second positioning member 32 and the first positioning member 231 is greater than twice the thickness of the web 450. Through the above arrangement, sufficient space is reserved for the web 450 before the individual pressurizing tooling unit 100 is connected to the web 450, preventing the individual pressurizing tooling unit 100 from damaging the web 450.

[0078] Furthermore, through the mutual cooperation of the first positioning member 231 and the second positioning member 32, the smooth installation of the individual pressurizing tooling unit 100 and the web 450 can be achieved, and at the same time, the web 450 is positioned. Meanwhile, the second positioning member 32 abuts against the outside of the web 450, which can prevent the web 450 from deforming outward. The first positioning member 231 abuts against the inside of the web 450, which can prevent the web 450 from shrinking and deforming inward. The second positioning member 32 and the first positioning member 231 correspond one by one and clamp the web 450, which can effectively prevent the web 450 from shrinking and deforming.

[0079] In step S130, the clamping frame 31 can be moved such that the clamping frame 31 drives the second positioning member 32 to approach the web 450, and the second positioning member 32 and the first positioning member 231 clamp the web 450 to define the chordal position of the web 450 on the blade housing. It can be understood that the clamping frame 31 can be driven to move by a driving member such as a cylinder or an electric cylinder. In order to synchronously move the clamping frames 31 of the multiple individual pressurizing tooling units 100, the air circuits of the cylinders can be connected in series or the control circuits of the electric cylinders can be connected in series.

[0080] In some embodiments, the pressurizing tooling unit 100 further includes a downward pressing component 40. In step S140, the web 450 is aligned and connected with the pressurizing tooling unit 100 and the outer shell forming die 300. Before the web 450 is connected to the housing 303 to be assembled, debugging of the downward pressing component 40 is also included. Among them, the debugging steps of the downward pressing component 40 include: rotating the lifting component 20 until the connecting flange 452 of the lifting member 22 and the web 450 are misaligned; moving the downward pressing component 40. Specifically, move the downward pressing component 40 so that the distance between the surface of the web 450 close to the housing 303 to be assembled and the housing 303 to be assembled is a preset distance. Through the above settings, the distance between the web 450 and the housing 303 to be assembled in the width direction N is uniform, so that the thickness of the adhesive 470 meets the requirements, thereby improving the quality of the blade 400.

[0081] In some embodiments, when the pressurizing tooling unit 100 is first used to assemble the web 450, the downward pressing component 40 can be debugged. After the debugging of the downward pressing component 40 is completed, the debugging steps of the downward pressing component 40 do not need to be repeated, and the web 450 can be directly aligned and connected with the pressurizing tooling unit 100 and the outer shell forming die 300 so that the web 450 is connected to the housing 303 to be assembled.

[0082] Specifically in implementation, the downward pressing component 40 is connected to the first bracket 11 by a screw. When debugging the downward pressing component 40, the screw can be adjusted to ensure that the thickness of the adhesive 470 is a preset distance. After the debugging is completed, lock the screw to optimize the thickness of the adhesive 470. Optionally, the screw can be locked by spot welding with an electric welding machine. During later use, there is no need to operate on the screw position of the downward pressing component 40, which is convenient to use.

[0083] In some embodiments, when installing the web 450, first place the web 450 on the web bracket 202, and then move the clamping brackets 31 of each pressurizing tooling unit 100 so that the distance between the second positioning member 32 and the first positioning member 231 is greater than the thickness of the web 450. Then use the lifting component 500 to place each pressurizing tooling unit 100 on the corresponding tooling bracket 201 in turn; after the placement is completed, rotate the lifting component 20 of each pressurizing tooling unit 100 so that the lifting member 22 is connected to the connecting flange 452 of the web 450, and move the clamping brackets 31 of each pressurizing tooling unit 100 so that the first positioning member 231 and the second positioning member 32 clamp the web 450 to complete the connection between the web 450 and the pressurizing tooling unit 100. Then use the lifting component 500 to lift the lifting arm 50, and slowly adjust the position of the lifting component 500 until the hook structures on the lifting arms 50 of all pressurizing tooling units 100 cooperate with the lifting component 500. Finally, lift the lifting component 500 to realize the overall lifting of the lifting component 500, the pressurizing tooling unit 100 and the web 450.

[0084] Please refer to Figure 8 , Figure 8 which shows a schematic structural view of a blade according to an embodiment of the present invention. An embodiment of the present invention also provides a blade 400, which is made by using the above-mentioned blade forming method.

[0085] In some embodiments, the blade 400 includes a blade housing and webs 450 used in pairs. The blade housing has an axial direction and a chord direction Y. The housing has a leading edge 430 and a trailing edge 440 in its chord direction Y. The blade housing includes a windward surface housing 410 and a leeward surface housing 420. The windward surface housing 410 and the leeward surface housing 420 are oppositely arranged, and the windward surface housing 410 and the leeward surface housing 420 are buckled to form a hollow space 460. The webs 450 are arranged in the hollow space 460, and the webs 450 are respectively connected to the windward surface housing 410 and the leeward surface housing 420. The blade 400 provided by the embodiment of the present invention is made by the above-mentioned blade forming method. By reasonably adjusting the single pressurizing tool 100, the single pressurizing tool 100 can safely and accurately connect the webs 450 to the blade housing, prevent damage to the webs 450, improve the quality of the formed blade 400, improve the manufacturing efficiency of the blade 400 and the quality of the blade 400. Therefore, it is easy to promote and apply.
