Fig. 3 is a schematic view of a part of a web pressing tool, a blade forming mold and a web after being assembled according to an embodiment of the present application. In some embodiments, referring to fig. 1 and 3, the web pressurizing tool 40 further includes a first web bracket 431 and a first connection assembly 44, the first web bracket 431 is connected to one side of the tool body 41 along the first direction X, and the first connection assembly 44 is provided on the first web bracket 431 and/or the tool body 41 and is capable of connecting the first web 10.
When the first web 10 is assembled, the first web 10 may be connected by the first connecting component 44, the first connecting component 44 may be disposed on the first web bracket 431 or may be disposed on the tool body 41, and the first web bracket 431 is connected to the tool body 41. The tooling body 41 can drive the first web 10 to move when moving under the lifting of the lifting mechanism, so that the web pressurizing tooling 40 can hoist the first web 10 to a proper position of the blade forming die 2, the assistance of other mechanisms is not needed, and the assembly process of the first web 10 is simplified.
The first web bracket 431 may be fixedly connected to the tool body 41 by screw connection, welding or a suitable manner. The tool body 41 may be a steel frame structure. The first web bracket 431 may include a vertical beam extending along the second direction Y, and the vertical beam is connected to the steel frame beam body on one side of the tooling body 41 along the first direction X.
In some embodiments, web press tooling 40 further includes a second web support 432 and a second connection assembly 45. Fig. 4 is a schematic structural view of a second web bracket and a second connection assembly of a web pressing tool according to an embodiment of the present application. Referring to fig. 1 and 4, the second web bracket 432 is connected to the other side of the tooling body 41 along the first direction X. The second connection assembly 45 is provided on the second web support 432 and is capable of connecting the second web 20.
When the first web 10 and the second web 20 are assembled, the first connecting component 44 is connected with the first web 10, the second connecting component 45 is connected with the second web 20, and then the first web 10 and the second web 20 can be hoisted to the proper positions of the blade forming die 2 at the same time by moving the tool body 41, so that the simultaneous hoisting and simultaneous bonding of the first web 10 and the second web 20 are realized, and the assembly efficiency of the webs and the production efficiency of the blades are further improved.
In addition, the first web bracket 431 and the second web bracket 432 are respectively connected to two opposite sides of the tool body 41 along the first direction X, and the first web bracket 431 and the second web bracket 432 are spaced apart along the first direction X, so that structural interference is not generated. The first connecting component 44 arranged on the first web bracket 431 or the tooling body 41 and the second connecting component 45 arranged on the second web bracket 432 are also spaced along the first direction X, so that the first web 10 and the second web 20 are conveniently connected respectively, the first web 10 and the second web 20 are hoisted at the same time, and the conditions of structural interference, collision damage and the like are avoided.
In some embodiments, the second web support 432 may extend away from the tooling body 41 along the first direction X such that the second web support 432 and the first web support 431 are spaced apart a distance along the first direction X, which is advantageous for the first web 10 and the second web 20 to be spaced apart in the first direction X and to reduce the size of the tooling body 41 along the first direction X.
Optionally, the second web support 432 may comprise a plurality of first beams 4321 extending in the first direction X, and at least one second beam 4322 extending in the second direction Y, the second beam 4322 being connected to an end of the first beam 4321 facing away from the tooling body 41 in the first direction X. The second connection assembly 45 may be provided to the second beam 4322, whereby the first web 10 connected to the first connection assembly 44 and the second web 20 connected to the second connection assembly 45 may have a maximum spacing in the first direction X on the premise that the size of the web pressing tool 40 in the first direction X is constant, minimizing the size of the web pressing tool 40 in the first direction X.
Further, the first pressing mechanism 421 is disposed on the tool body 41, and the second pressing mechanism 422 is disposed on the second web support 432.
The first pressing mechanism 421 is directly disposed on the tool body 41, but not on the first web bracket 431, so that the structure of the first web bracket 431 can be simplified. The second pressing mechanism 422 is disposed on the second web support 432, so that the second pressing mechanism 422 is positioned opposite to the second web 20, and thus presses the second web 20 along the second direction Y.
Alternatively, in a state in which the web pressing tool 40 hangs the first web 10 and the second web 20, the first web 10 may be located at one side of the tool body 41 in the second direction Y and adjacent to one end portion of the tool body 41 in the first direction X; the second web 20 may be on one side of the second web support 432 in the second direction Y and adjacent an end of the second web support 432 facing away from the tooling body 41.
Illustratively, the second direction Y may be an up-down direction, i.e., a height direction, and the first direction X may be a transverse direction, i.e., a chord direction, and the first web 10 may be located below a transverse end portion of the tooling body 41. The second web 20 may be below the lateral end of the second web support 432 facing away from the tooling body 41. The first pressurizing mechanism 421 may be disposed at a position directly above the first web 10 of the tool body 41, and the second pressurizing mechanism 422 may be disposed at a position directly above the second web 20 of the second web support 432.
In some embodiments, referring to fig. 1, the web pressing tool 40 further includes a third web bracket 433, where the third web bracket 433 is disposed on a side of the second web bracket 432 facing away from the first web bracket 431 in the first direction X, and the third web bracket 433 is connected to the second web bracket 432 or is capable of being connected to the blade forming mold 2. The third pressurizing mechanism 423 is provided to the third web frame 433.

The third web support 433 is disposed on a side of the second web support 432 facing away from the first web support 431 along the first direction X, so as to correspond to the position of the third web 30. The first web brackets 431, the second web brackets 432 and the third web brackets 433 are sequentially arranged along the first direction X and are arranged at intervals.
Since the third web frame 433 is adjacent to the second web frame 432 along the first direction X, the third web frame 433 can be connected to the second web frame 432, and the third web frame 433 can move along with the tool body 41, which is beneficial to simplifying the assembly operation.
Since the third web 30 is located at the edge of the blade forming die 2 in the first direction X and is closer to the blade forming die 2, in other embodiments, the third web bracket 433 may be connected to the blade forming die 2, which is advantageous for simplifying the structure of the third web bracket 433.
Further, the web pressurizing tool 40 may further include a third connecting component, which may be provided on the third web bracket 433 and may be capable of connecting to the third web 30. When the third web support 433 is connected to the second web support 432, the third web 30 may be connected to the web press tooling 40 by a third connection assembly. The web pressurizing tool 40 can hoist the first web 10, the second web 20 and the third web 30 to the blade forming die 2 at the same time, so that the first web 10, the second web 20 and the third web 30 are bonded to the blade forming die 2 at the same time, and the web assembly efficiency and the blade forming efficiency are improved to the greatest extent. When the third web support 433 is connected to the blade forming mold 2, other lifting mechanisms are needed to lift the third web 30, and after the lifting mechanisms lift the third web 30 to the blade forming mold 2, the third web 30 is pressurized by the third pressurizing mechanism 423 on the third web support 433, so that the third web 30 is connected to the blade forming mold 2. The pressing of the third web 30 may be performed simultaneously with the pressing of the first web 10 and the second web 20 to improve web assembly efficiency.
In some embodiments, the tooling body 41 extends in an axial direction of the blade forming die 2.
