Description

Technical Field

[0001] This invention relates to the field of wind turbine blade manufacturing technology, and in particular to a method for matching the tiles of multiple tile molds with multiple main molds for wind turbine blades. Background Technology

[0002] In the production of wind turbine blades, the blade sheet is a product made from the blade sheet mold. A blade sheet manufactured from a single mold can be easily matched with multiple main molds. However, when blade sheets from two or more molds are matched with multiple main molds, significant differences arise. Firstly, differences between the different molds themselves lead to variations in the manufactured blade sheets. Secondly, the installation of the pre-embedded flanges within each mold varies. These differences accumulate during matching, resulting in substantial discrepancies between blade sheets manufactured from two or more molds and multiple main molds, making it difficult to achieve consistent matching. Although existing technologies offer some methods for adjusting the molds, none provide precise and detailed adjustment techniques, leading to final adjustments that fail to meet matching requirements. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a matching method for wind turbine blade tiles, tile molds, and main molds, thereby solving the technical problem that existing technologies lack accurate and detailed adjustment methods for matching tiles and molds.

[0004] This invention provides a method for matching wind turbine blade tiles, tile molds, and main molds, comprising the following processes:

[0005] First, the tiles manufactured by the first tile mold are matched on each main mold: the height and width of the mold frustum of the main mold are adjusted by adjusting the pre-embedded flange base in the main mold until the gap between the tile and the main mold surface is less than 2 mm and the gap between the frustum is less than 2 mm.

[0006] Then, the tiles manufactured by the first tile mold are matched with the other tile molds: the height and width of the mold truncated pyramid of the tile mold are adjusted by adjusting the pre-embedded flange base in the tile mold until the gap between the tile and the mold surface is less than 1 mm and the gap between the truncated pyramids is less than 1 mm.

[0007] Finally, the tiles manufactured by the other matched tile molds are matched with the main molds in turn: the height and width of the mold frustum of the main mold are adjusted by adjusting the pre-embedded flange base in the main mold until the gap between the tile and the main mold surface is less than 2 mm and the gap between the frustum is less than 2 mm.

[0008] Ultimately, the tiles from multiple tile molds are matched and qualified in multiple main molds.

[0009] Furthermore, during the adjustment process, when the tile becomes horizontally biased, that is, when the gap between the tile and the mold truncated pyramid is greater than 2 mm; when there is no gap between the tile and the mold surface on one side, and the gap on the other side is greater than 2 mm, the pre-embedded flange base is adjusted to move the tile horizontally to the side with the larger gap, so that the gap is evenly distributed to the front and rear edge surfaces.

[0010] Furthermore, during the adjustment process, when the tile rotates and shifts, that is, when the gap between the tile and the mold prism is greater than 3 mm on one side and there is no gap on the other side, the embedded flange base on the side where the gap between the tile and the mold prism is greater than 3 mm is lowered; the embedded flange base on the side where there is no gap between the tile and the mold prism is raised until the gap between the tile and the mold prism is within the range of 0-2 mm.

[0011] Furthermore, during the adjustment process, when the mold truncated cone at the end of the tile is too high, that is, when there is no gap between the tile and the mold truncated cone, the side surface of the tile is taut and does not fit with the mold surface, the mold truncated cone at that point in the main mold is ground down until the side surface of the tile fits with the mold surface.

[0012] When the end mold truncated cone of the tile is too low, that is, when the gap between the tile and the mold truncated cone is 2-5 mm, the tile surface bends and bulges inside the mold and does not fit with the mold surface, the mold truncated cone at that point in the main mold is raised until the side surface of the tile fits with the mold surface.

[0013] Furthermore, during the adjustment process, when the mold truncated cone at the end of the tile is too high, that is, when there is no gap between the tile and the mold truncated cone, the side profile of the tile is taut and does not fit with the mold profile, the mold truncated cone at that point in the tile mold is raised until the side profile of the tile fits with the mold profile.

[0014] When the end of the tile mold is too low, that is, when the gap between the tile and the mold mold is 2-5 mm, the tile surface bends and bulges inside the mold and does not fit with the mold surface, reduce the mold mold at that point until the side surface of the tile fits with the mold surface.

[0015] Furthermore, during the adjustment process, when the tile truncated pyramid is high, that is, when the gap between the tile and the mold truncated pyramid is greater than 2 mm, and the tile surface is in contact with the mold surface within the mold gap of 0-2 mm, the mold truncated pyramid of the main mold is increased until the gap between the tile truncated pyramid and the mold truncated pyramid of the main mold is within the range of 0-2 mm; or the mold truncated pyramid of the tile mold is decreased until the gap between the tile truncated pyramid and the mold truncated pyramid of the tile mold is within the range of 0-2 mm.

[0016] When the tile truncated pyramid is wide, that is, when the gap between the tile and the mold truncated pyramid is 0-2 mm and the gap between the tile and the mold truncated pyramid slope is greater than 2 mm, and the tile fits the mold surface, the slope of the main mold truncated pyramid will be widened until the gap between the tile truncated pyramid and the main mold truncated pyramid slope is within the range of 0-2 mm; or the slope of the tile mold will be narrowed until the gap between the tile truncated pyramid and the tile mold truncated pyramid slope is within the range of 0-2 mm.

[0017] Furthermore, during the adjustment process, when the mold truncated pyramid is high, that is, when there is no gap between the tile and the mold truncated pyramid, and the tile surface does not fit the mold surface when the gap between the tile and the mold truncated pyramid is greater than 2 mm, the mold truncated pyramid of the main mold is reduced until the gap between the tile truncated pyramid and the mold truncated pyramid of the main mold is within the range of 0-2 mm; or the mold truncated pyramid of the tile mold is increased until the gap between the tile truncated pyramid and the mold truncated pyramid of the tile mold is within the range of 0-2 mm.

[0018] When the mold truncated pyramid is wide, that is, when the gap between the tile and the mold truncated pyramid is greater than 2 mm, and there are resistance points between the tile and the mold truncated pyramid slope, and it does not fit the mold surface, the slope of the main mold truncated pyramid is narrowed until the gap between the tile truncated pyramid and the main mold truncated pyramid slope is within the range of 0-2 mm; or the slope of the tile mold is widened until the gap between the tile truncated pyramid and the tile mold truncated pyramid slope is within the range of 0-2 mm.

[0019] Furthermore, during the adjustment process, when the tile flange is low, that is, when the gap between the tile and the mold truncated pyramid is greater than 2 mm, the gap between the tile and the mold truncated pyramid slope is greater than 2 mm, there is no gap between the tile flange and the mold flange, and the tile does not fit the mold surface, the tile mold flange is raised until the gap between the tile truncated pyramid and the mold truncated pyramid slope is within the range of 0-2 mm.

[0020] When the tile flange is high, i.e. the gap between the tile and the mold prism is 0-2 mm, the gap between the tile flange and the mold flange is greater than 2 mm, and the tile fits the mold surface, and the vacuum film will puncture at the tile flange, the tile flange at that position in the main mold is raised until the gap between the tile flange and the mold flange is within the range of 0-2 mm.

[0021] Furthermore, during the adjustment process, when the mold flange is low, that is, when the gap between the tile and the mold prism is 0-2 mm, the gap between the tile flange and the mold flange is greater than 2 mm, the tile is in contact with the mold surface, and the vacuum film will puncture at the tile flange, the flange at that position in the main mold is raised until the gap between the tile flange and the mold flange is within the range of 0-2 mm.

[0022] When the mold flange is too high, that is, the gap between the tile and the mold truncated pyramid is greater than 2 mm, the gap between the tile and the mold truncated pyramid slope is greater than 2 mm, there is no gap between the tile flange and the mold flange, and the tile does not fit the mold surface, the tile mold flange is raised until the gap between the tile truncated pyramid and the mold truncated pyramid slope is 0-2 mm, and the tile does not fit the mold surface.

[0023] The beneficial effects of this invention are:

[0024] This invention solves the problem of mismatch between tiles from two or more tile molds and multiple main molds by adjusting the matching between the tiles and each mold. For several types of mismatch, this invention provides key data and corresponding adjustment methods, enabling operators to better adjust the molds and improve the matching accuracy between tiles from multi-tile molds and each main mold.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The present invention will be further illustrated below with reference to specific embodiments. Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Modifications to the present invention in various equivalent forms all fall within the scope defined by the appended claims.

[0043] like Figure 1-3 As shown, the present invention provides a method for matching the blade, the blade mold, and the main mold of a wind turbine blade, comprising the following processes:

[0044] First, the tiles 1 manufactured by the first tile mold 2 are matched on each main mold 22: the height and width of the mold frustum 21 of the main mold 2 are adjusted by adjusting the pre-embedded flange base in the main mold 22 until the surface gap A between the tile 1 and the main mold 2 is less than 2 mm and the frustum gap B is less than 2 mm.

[0045] Then, the tile 1 manufactured by the first tile mold 2 is matched on each of the other tile molds 2: the height and width of the mold frustum 21 of the tile mold 2 are adjusted by adjusting the pre-embedded flange base in the tile mold 2 until the surface gap A between the tile 1 and the tile mold 2 is less than 1 mm and the frustum gap B is less than 1 mm.

[0046] Finally, the tiles 1 manufactured by the other matched tile molds 2 are matched with each main mold 2 in turn: the height and width of the mold frustum 21 of the main mold 2 are adjusted by adjusting the pre-embedded flange base in the main mold 2 until the surface gap A between the tile 1 and the main mold 2 is less than 2 mm and the frustum gap B is less than 2 mm.

[0047] Ultimately, the tiles 1 of multiple tile molds 2 are matched and qualified in multiple master molds 2.

[0048] Taking four tile molds as an example:

[0049] First, match the tiles of No. 1 tile mold 2 to the main mold 2. By fine-tuning the pre-embedded flange base in the main mold 2, increase or decrease the height and width of the mold truncated pyramid 21, so that the gap A between the tile and the main mold 2 is less than 2 mm and the gap B between the truncated pyramid is less than 2 mm.

[0050] Next, match tile 1 from tile mold 2 to tile mold 2. By fine-tuning the pre-embedded flange base in tile mold 2 and increasing or decreasing the height and width of the frustum 21 in tile mold 2, the gap between tile 1 and tile mold 2 is less than 1 mm, and the gap between the frustums is less than 1 mm. Similarly, match tile 1 from tile mold 2 to tile molds 3 and 4.

[0051] Finally, the tiles 1 from the matching molds 2, 3, and 4 are matched with the main molds 2 in the same way as the matching of the tiles 1 from the first mold 2 with the main molds 2.

[0052] like Figure 4 As shown, during the adjustment process, when tile 1 is horizontally deviated, that is, when the gap B between tile 1 and mold frustum 21 is greater than 2 mm; when there is no gap between tile 1 and mold 2 on one side of the mold surface, and the gap A on the other side of the mold surface is greater than 2 mm, the pre-embedded flange base is adjusted to move the tile horizontally to the side with the larger gap, and the gap is evenly distributed to the front and rear edge mold surfaces.

[0053] like Figure 5 As shown, during the adjustment process, when the tile 1 rotates and shifts, that is, when the gap B between the tile and the mold truncated pyramid 21 is greater than 3 mm on one side and has no gap on the other side, the embedded flange base on the side where the gap B between the tile and the mold truncated pyramid 21 is greater than 3 mm is lowered; the embedded flange base on the side where the gap between the tile and the mold truncated pyramid 21 has no gap is raised until the gap B between the tile and the mold truncated pyramid 21 is within the range of 0-2 mm.

[0054] like Figure 6 , 7 As shown, during the adjustment process, when the mold truncated pyramid 21 at the end of the tile is too high, that is, when there is no gap between the tile and the mold truncated pyramid 21, the side profile C of the tile is taut and does not fit with the mold profile, the mold truncated pyramid 21 at that location in the main mold 2 is ground down until the side profile of the tile fits with the mold profile. However, this adjustment method will cause the mold closing gap of the blade mold to increase and the mold closing adhesive layer to become thicker. It is also necessary to adjust the mold closing gap at that location. Therefore, the preferred adjustment method is to raise the mold truncated pyramid 21 at that location in the tile mold 2 until the side profile of the tile fits with the mold profile.

[0055] When the mold truncated pyramid 21 at the end of the tile is too low, that is, when the gap between the tile and the mold truncated pyramid 21 is 2-5 mm, the tile surface bends and bulges C in the mold and does not fit with the mold surface, the mold truncated pyramid 21 at that point in the main mold 2 is raised until the side surface of the tile fits with the mold surface. However, this adjustment method will cause the mold closing gap of the blade mold to become smaller and the mold closing adhesive layer to become thinner. The mold closing gap at that point also needs to be adjusted. Therefore, the preferred adjustment method is to lower the mold truncated pyramid 21 at that point in the tile mold 2 until the side surface of the tile fits with the mold surface.

[0056] like Figure 8 , 9 As shown, during the adjustment process, when the tile truncated pyramid 11 is high, that is, when the gap B between the tile 1 and the mold truncated pyramid 21 is greater than 2 mm, and the tile surface is in the range of 0-2 mm in the mold gap A, when it fits with the mold surface, the mold truncated pyramid 21 of the main mold 2 is raised until the gap between the tile truncated pyramid 11 and the mold truncated pyramid 21 of the main mold 2 is in the range of 0-2 mm. However, this adjustment method will cause the mold closing gap of the blade mold to become smaller and the mold closing adhesive layer to become thinner. It is also necessary to adjust the mold closing gap of the tile area. Therefore, the preferred adjustment method is to lower the mold truncated pyramid 21 of the tile mold 2 until the gap between the tile truncated pyramid 11 and the mold truncated pyramid 21 of the tile mold 2 is in the range of 0-2 mm.

[0057] When the tile truncated pyramid 11 is wide, that is, when the gap B between the tile 1 and the mold truncated pyramid 21 is within the range of 0-2 mm, and the slope gap C between the tile 1 and the mold truncated pyramid 21 is greater than 2 mm, when it fits with the mold surface, the slope of the main mold 2 truncated pyramid 21 is widened until the slope gap between the tile truncated pyramid 11 and the mold truncated pyramid 21 of the main mold 2 is within the range of 0-2 mm. However, this adjustment method will lead to an increase in the amount of mold closing glue used. Therefore, the preferred adjustment method is to narrow the slope of the tile mold 2 until the slope gap between the tile truncated pyramid 11 and the mold truncated pyramid 21 of the tile mold 2 is within the range of 0-2 mm.

[0058] like Figure 10 , 11 As shown, during the adjustment process, when the mold truncated pyramid 21 is high, that is, when the gap B between the tile 1 and the mold truncated pyramid 21 is 0, and the tile surface does not fit the mold surface when the gap A between the mold and the mold is greater than 2 mm, the mold truncated pyramid 21 of the main mold 2 is reduced until the gap between the tile truncated pyramid 11 and the mold truncated pyramid 21 of the main mold 2 is within the range of 0-2 mm. However, this adjustment method will cause the mold closing gap to increase and the mold closing adhesive layer to become thicker. It is also necessary to adjust the mold closing gap of the tile area. Therefore, the preferred adjustment method is to increase the mold truncated pyramid 21 of the tile mold 2 until the gap between the tile truncated pyramid 11 and the mold truncated pyramid 21 of the tile mold 2 is within the range of 0-2 mm.

[0059] When the mold frustum 21 is wide, that is, when the gap between the tile and the mold frustum 21 is greater than 2 mm, and the tile 1 has a resistance point C on the slope of the mold frustum 21 and does not fit the mold surface, the slope of the main mold 2 frustum 21 is narrowed until the gap between the tile frustum 11 and the slope of the main mold 2 mold frustum 21 is within the range of 0-2 mm. However, this adjustment method will weaken the frustum strength in the tile area of ​​the mold. Therefore, the preferred adjustment method is to widen the slope of the tile mold 2 until the gap between the tile frustum 11 and the slope of the tile mold 2 mold frustum 21 is within the range of 0-2 mm.

[0060] like Figure 12 , 13 As shown, during the adjustment process, when the tile flange 12 is low, that is, when the gap B between the tile 1 and the mold truncated pyramid 21 is greater than 2 mm, the slope gap C between the tile 1 and the mold truncated pyramid 21 is greater than 2 mm, and the gap A between the tile flange 12 and the mold flange 22 is 0, and the tile 1 does not fit the mold surface, the tile mold 2 flange 22 is raised until the slope gap between the tile truncated pyramid 11 and the mold truncated pyramid 21 is within the range of 0-2 mm;

[0061] When the tile flange 12 is high, that is, the gap B between the tile and the mold frustum 21 is 0-2 mm, and the gap C between the tile flange 12 and the mold flange 22 is greater than 2 mm, when the tile fits the mold surface, if there is no abnormality when the tile is vacuumed in the main mold 2, no treatment is required; when the vacuum film is frequently punctured at the tile flange 12, the flange at this position of the main mold 2 needs to be raised until the gap between the tile flange 12 and the mold flange 22 is 0-2 mm.

[0062] like Figure 14 , 15 As shown, during the adjustment process, when the mold flange 22 is low, that is, when the gap B between the tile 1 and the mold truncated pyramid 21 is 0-2 mm and the gap C between the tile flange 12 and the mold flange 22 is greater than 2 mm, and the tile 1 is in contact with the mold surface, if the tile 1 is normal under vacuum conditions of the main mold 2, no treatment is required; when the vacuum film is frequently punctured at the tile flange 12, the flange at this position of the main mold 2 needs to be raised until the gap between the tile flange 12 and the mold flange 22 is 0-2 mm.

[0063] When the mold flange 22 is high, that is, the gap A between the tile and the mold truncated pyramid 21 is greater than 2 mm, the slope gap C between the tile and the mold truncated pyramid 21 is greater than 2 mm, and the gap B between the tile flange 12 and the mold flange 22 is 0, and the tile does not fit the mold surface, the tile mold 2 flange 22 is raised until the slope gap between the tile truncated pyramid 11 and the mold truncated pyramid 21 is between 0-2 mm, and the tile does not fit the mold surface.

[0064] In the above description, the mold tile area profile and the theoretical position of the flange in the main mold 2 and tile mold 2 are measured using a laser tracker. Tile: The product made by the wind turbine blade tile mold 2; Tile mold 2: The mold used to produce tiles for wind turbine blades; Main mold 2: The mold used to produce blades for wind turbine blades; Tile frustum 11: The elongated strip-shaped surface protruding from both sides of the front and rear edges of the tile; Tile flange: The plane extending from both sides of the front and rear edges of the tile; Mold frustum 21: The elongated strip-shaped surface protruding from both sides of the front and rear edges of the mold used to produce blades for wind turbine blades; Mold flange 22: The plane extending from both sides of the front and rear edges of the mold.
