Description

Technical Field

[0001] This utility model relates to the field of aircraft canopy technology, and in particular to a U-shaped sheet mold for an aircraft canopy. Background Technology

[0002] With the development of wind power generation, the external dimensions of nacelle covers are becoming increasingly larger. To facilitate transportation, most nacelle covers adopt a segmented design. Therefore, most nacelle covers have a U-shaped sheet structure. During the manufacturing process, this structure undergoes varying degrees of shrinkage and deformation depending on the installation location, and even slight deviations can lead to assembly difficulties.

[0003] As the size of U-shaped sheets increases, the mold body also gradually becomes larger, making the requirements for size control and production conditions of U-shaped sheets increasingly stringent. Conventional molds are difficult to meet the size control requirements of U-shaped sheets, easily resulting in excessive or insufficient shrinkage and deformation of the U-shaped sheets, low product qualification rate, and difficulty for on-site workers to install the U-shaped sheets. Utility Model Content

[0004] This utility model provides a U-shaped sheet mold for a cabin cover to solve the technical problem of difficult control of shrinkage and deformation of the U-shaped sheet and low product qualification rate.

[0028] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0030] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0031] Please see Figures 1-4 The present invention provides a U-shaped mold for a cabin cover, comprising a male mold 1 located at the top and a mold body 2 located at the bottom. After the male mold 1 and the mold body 2 are closed, they together form a mold cavity 3 for forming a U-shaped cabin cover 4.

[0032] Please see Figures 1-2 A fixed frame 5 is provided below the mold body 2 to support the mold body 2. An adjustment mechanism 6 is provided on both sides of the mold body 2 on the fixed frame 5. One end of the adjustment mechanism 6 is fixedly connected to the fixed frame 5, and the other end is fixedly connected to the mold body 2. The adjustment mechanism 6 is used to adjust the elastic deformation of the mold body 2. In this way, when making U-shaped sheet 4 using the mold of this application, the size requirements of U-shaped sheet 4 can be met by finely adjusting the adjustment mechanism 6. One end of the adjustment mechanism 6 is fixedly connected to the fixed frame 5, and the other end can squeeze / stretch the mold body 2 to make the mold body 2 elastically deform, thereby adjusting the elastic deformation of the mold body 2, and then adjusting the elastic deformation of the U-shaped sheet 4 in the mold cavity 3 to meet the size requirements of U-shaped sheet 4. The product qualification rate is high, which solves the technical problem of difficult control of shrinkage deformation of U-shaped sheet 4.

[0033] Please see Figures 1-2The U-shaped fuselage cover 4 may include a first connecting portion 41 located at the bottom and second connecting portions 43 located on both sides of the first connecting portion 41. The first connecting portion 41 is arc-shaped, and the second connecting portions 43 are inclined outwards. The mold cavity 3 includes a first sub-mold cavity 31 for molding the first connecting portion 41 and a second sub-mold cavity 32 for molding the second connecting portion 43. The adjustment mechanism 6 is fixed at the corresponding position of the mold body 2 and the second sub-mold cavity 32. In this way, when the adjustment mechanism 6 is finely adjusted, the adjustment mechanism 6 squeezes / stretches the corresponding position of the mold body 2 and the second sub-mold cavity 32, making it easier for the mold body 2 to generate elastic deformation, so as to better solve the technical problem of difficult control of shrinkage deformation of the U-shaped cover 4. The U-shaped fuselage cover 4 may include, but is not limited to, fiberglass material. In this embodiment, the adjustment mechanism 6 is only designed on the left and right sides of the mold body 2 to form the second connecting portions 43 on both sides of the U-shaped fuselage cover 4. The first connecting portion 41 of the U-shaped cover 4 can achieve plasticity only by the weight of the male mold 1 and the support of the fixing frame 5.

[0034] The fixing frame 5 can adopt various structural forms readily conceived by those skilled in the art. However, for ease of implementation, in this embodiment, the fixing frame 5 may include multiple horizontal beams 51 and multiple vertical beams 52 arranged perpendicularly to the horizontal beams 51. The multiple horizontal beams 51 and multiple vertical beams 52 are fixedly connected, and the multiple vertical beams 52 are spaced apart along the length direction of the horizontal beams 51. The two outermost vertical beams 52 are connected to the mold body 2 through the adjustment mechanism 6, and the ends of the vertical beams 52 located on the inner side and corresponding to the first sub-mold cavity 313 are fixedly connected to the mold body 2. This fixing method using horizontal beams 51 and vertical beams 52 can reduce the overall weight of the mold and facilitate handling. The multiple horizontal beams 51 and multiple vertical beams 52 can all be hollow square tube structures, further reducing the overall weight of the mold and facilitating handling.

[0035] Please see Figure 1 The bottom of the fixed frame 5 can be equipped with casters 7, which can give the mold 360° planar mobility, while minimizing the movement resistance and facilitating transportation.

[0036] Please see Figure 2 The upper outer edge of the male mold 1 may be provided with a limiting platform 11, and the mold body 2 is provided with a stop 21 that cooperates with the limiting platform 11. The limiting platform 11 and the stop 21 cooperate to limit the displacement of the male mold 1 in the mold height direction, so as to facilitate the control of the thickness of the U-shaped sheet 4 and facilitate the forming of the U-shaped sheet 4.

[0037] The adjustment mechanism 6 can adopt various structural forms readily conceived by those skilled in the art, such as hydraulic telescopic rods, telescopic motors, etc.; however, for ease of implementation and cost reduction, this embodiment preferably adopts the following structural form:

[0038] Please see Figures 2-4The adjusting mechanism 6 may include a connecting nut 61. The two ends of the connecting nut 61 are respectively provided with a first threaded hole 611 and a second threaded hole 612. The helical direction of the first threaded hole 611 is opposite to that of the second threaded hole 612. A first bolt 62 is internally threaded into the first threaded hole 611, and a second bolt 63 is internally threaded into the second threaded hole 612. The bolt head of the first bolt 62 is fixedly connected to the fixing frame 5, and the bolt head of the second bolt 63 is fixedly connected to the mold body 2. By driving the connecting nut 61 to rotate, the first threaded hole 611 and the first bolt 62 cooperate, and the second threaded hole 612 and the second bolt 63 cooperate, so that the first bolt 62 and the second bolt 63 can be controlled to extend / retract simultaneously, thereby simultaneously squeezing / stretching both sides of the mold body 2, so that both sides of the mold body 2 are evenly stressed, thereby realizing the elastic deformation of the mold body 2.

[0039] Please see Figure 3 A metal plate 8 can be provided on the outer side of the mold body 2 at a position corresponding to the bolt head of the second bolt 63. The bolt head of the second bolt 63 is fixedly connected to the metal plate 8. The metal plate 8 increases the contact area between the bolt head of the second bolt 63 and the mold body 2, thereby improving force transmission and facilitating the compression / stretching of the mold body 2. In this embodiment, the metal plate 8 can be fixedly installed on the outer side of the mold body 2 by pre-embedding with fiberglass.

[0040] In this embodiment, the fixed connection between the crossbeam 51 and the vertical beam 52, the fixed connection between the vertical beam 52 and the mold body 2, the fixed connection between the bolt head of the first bolt 62 and the fixing frame 5, and the fixed connection between the bolt head of the second bolt 63 and the metal plate 8 can all adopt various connection methods that are easy for those skilled in the art to think of, such as riveting, bonding, etc.; however, in this embodiment, welding connection is adopted, which is convenient to implement and has good connection firmness.

[0041] In summary, the fabrication of the U-shaped sheet 4 using the U-shaped sheet mold of this utility model canopy can specifically include the following steps:

[0042] Step S1: Process the male mold 1 according to the processing drawing and process requirements of the U-shaped sheet 4;

[0043] In this step, when designing the U-shaped sheet 4, the processing drawing of the U-shaped sheet 4 needs to be enlarged by a certain proportion based on the required product size to avoid excessive dimensional deviations due to the shrinkage characteristics of the fiberglass material later.

[0044] Step S2: Process the surface of the male mold 1, and paste the fiberglass mold body 2 onto the male mold 1 according to the process requirements;

[0045] Step S2 may include the following steps:

[0046] Step S21: First, clean the surface of the male mold 1 with clean white cotton yarn;

[0047] Step S22: Apply sealing agent and release agent to the surface of male mold 1;

[0048] Step S23: Spray mold gel coat onto the surface of male mold 1;

[0049] Step S24: Hand lay up the fiberglass layer until the required thickness of the mold body 2 is achieved; the mold body 2 is now complete.

[0050] Step S3: On the mold body 2, weld the fixing frame 5 and the adjustment mechanism 6 according to the mold shape;

[0051] Step S3 may include the following steps:

[0052] Step S31: According to the design drawings of the fixing frame 5, the fixing frame 5 is welded using square tubes to conform to the shape of the mold.

[0053] Step S32: Add adjustment mechanisms 6 to both sides of the fixed frame 5 and weld them together with the fixed frame 5.

[0054] Step S32 may include the following steps:

[0055] Step S321: At one end of the mold body 2 near the adjustment mechanism 6 (i.e., the bolt head of the second bolt 63), a fiberglass embedded metal plate 8 is pasted on to increase the contact area between the adjustment mechanism 6 and the mold body 2, which facilitates pressure or stretching.

[0056] Step S322: Weld one end of the adjusting mechanism 6 (i.e., the bolt head of the second bolt 63) to the embedded metal plate 8;

[0057] Step S323: Weld the other end of the adjusting mechanism 6 (i.e., the bolt head of the first bolt 62) to the reinforcing steel frame;

[0058] Step S4: After the mold body 2 is completely cured and the fixing frame 5 is processed, the mold body 2 is demolded.

[0059] Step S5: According to the size requirements of the U-shaped sheet 4, pressure or tension is generated by the adjustment mechanism 6 on the fixing frame 5 to cause the mold body 2 to undergo elastic deformation, thereby adjusting the mold body 2 to meet the size requirements of the U-shaped sheet 4.
