[0042] Embodiment 1

[0043] Figure 1 This is a flow chart of a material surface processing method provided by the first embodiment of the present invention. This embodiment can be applied to determine a reasonable target bending corrugation curve, and perform surface processing on materials that need to be preformed and bent according to the target bending corrugation curve. The method can be executed by a material surface processing device, which can be implemented by software and / or hardware, and can generally be integrated in an electronic device. The electronic device can be a terminal device or a server device. The embodiment of the present invention does not limit the specific device type of the electronic device. Accordingly, Figure 1 As shown, the method includes the following operations:

[0044] S110, obtaining plane profile information of the material to be processed; wherein the plane profile information of the material to be processed includes a curvature radius value of a bending start position, a curvature radius value of a bending end position, and a corrugation height value of the material to be processed.

[0045] Among them, the material to be processed can be a material that needs to be preformed and bent on the inner arc side. The plane contour information can be basic arc feature information used to represent the material to be processed. The curvature radius value of the bending starting position can be the radius value at the starting position used to represent the arc feature of the material to be processed. Optionally, the value of the curvature radius value of the bending starting position can be set according to actual needs, such as being set to 2800, 2850 or 2900mm, etc., and the embodiment of the present invention does not limit the specific value of the curvature radius value of the bending starting position. The curvature radius value of the bending end position can be the radius value at the end position used to represent the arc feature of the material to be processed. Optionally, the value of the curvature radius value of the bending end position can be set according to actual needs, such as being set to 2805, 2810 or 2815mm, etc., and the embodiment of the present invention does not limit the specific value of the curvature radius value of the bending end position. The corrugation height value can be a length value used to represent the thickness direction of the material to be processed. Optionally, the corrugation height value may be set according to actual needs, such as 2, 2.5 or 3 mm, etc. The embodiment of the present invention does not limit the specific numerical value of the corrugation height value.

[0046] In an embodiment of the present invention, the material to be processed can be a composite material arc-shaped part that needs to be pre-formed and bent on the inner arc side, or it can be a local arc-shaped part that needs to be pre-formed and bent on the inner arc side. After obtaining the material to be processed, the curvature radius value of the bending starting position, the curvature radius value of the bending ending position and the corrugation height value of the material to be processed can be determined according to the material to be processed to obtain the target bending corrugation curve. The embodiment of the present invention does not specifically limit the material to be processed.

[0047] S120, determining a target bending corrugation curve according to the curvature radius value of the bending start position, the curvature radius value of the bending end position, and the corrugation height value.

[0048] The target bending corrugation curve may be a curve used to describe the corrugation characteristics of the material to be processed after the pre-forming bending process.

[0049] Furthermore, the curvature radius value of the bending start position, the curvature radius value of the bending end position and the corrugation height value of the material to be processed can be used to draw a target bending corrugation curve, so as to generate a target corrugated surface of the material to be processed using the target bending corrugation curve.

[0050] S130, generating a target corrugated surface of the material to be processed according to the target bending corrugation curve.

[0051] The target corrugated surface may be a surface drawn from a target bent corrugated curve.

[0052] Correspondingly, the target bending corrugation curve obtained in the above steps can be used to perform multi-section surface fitting and drawing to obtain the target corrugation surface, or the target bending corrugation curve obtained in the above steps can be used to perform multi-section surface fitting and drawing to obtain a reference corrugation surface, and then the reference corrugation surface is symmetrically and arrayed to obtain the target corrugation surface. The embodiment of the present invention does not specifically limit the method for generating the target corrugation surface.

[0053] Since the target bending corrugation curve is obtained by the corrugation height value described by the curvature radius value of the bending starting position and the curvature radius value of the bending end position, and the target corrugated surface is obtained by fitting the target bending corrugation curve, the material with such corrugated characteristics has an expandable manufacturing margin in the subsequent inner arc side pre-forming bending process, which can solve the problem of unreasonable corrugated surface design applicable to existing materials, and can improve the rationality of the corrugated surface design, so that the material with corrugated surface characteristics can fit the mold completely and tightly.

[0054] The technical solution of this embodiment first obtains the plane contour information of the material to be processed, the plane contour information of the material to be processed includes the curvature radius value of the bending starting position, the curvature radius value of the bending ending position and the corrugation height value of the material to be processed, and then determines the target bending corrugation curve according to the curvature radius value of the bending starting position, the curvature radius value of the bending ending position and the corrugation height value, and finally generates the target corrugated surface of the material to be processed according to the target bending corrugation curve, which solves the problem of unreasonable design of corrugated surfaces applicable to materials, can improve the rationality of corrugated surface design, so that materials with corrugated surface characteristics can fit the mold completely and tightly.

[0055] Embodiment 2

[0056] Figure 2 is a flow chart of a method for processing a curved surface of a material provided in the second embodiment of the present invention. This embodiment is specific based on the above embodiment. In this embodiment, a variety of specific optional implementation methods for generating a target bending corrugated curve and a target corrugated surface are provided. Figure 2 As shown, the method of this embodiment may include:

[0057] S210, determining pre-bending processing parameters; wherein the pre-bending processing parameters include the curvature radius value of the bending start position, the curvature radius value of the bending end position, and the corrugation height value.

[0058] S220, performing pre-bending processing on the part manufacturing margin of the material to be processed according to the pre-bending processing parameters to obtain the material to be processed.

[0059] The pre-bending processing parameter may be an index parameter for the pre-bending processing. The part manufacturing margin may be a material margin that can be expanded and reserved for the material to be processed in order to realize the bending processing.

[0060] In the embodiment of the present invention, the pre-bending processing parameters are first determined, and the pre-bending processing parameters can be the curvature radius value of the bending start position, the curvature radius value of the bending end position, or the corrugation height value. Further, the part manufacturing allowance of the material to be processed is obtained, and the part manufacturing allowance of the material to be processed is pre-bent using the curvature radius value of the bending start position, the curvature radius value of the bending end position, and the corrugation height value, thereby obtaining the material to be processed.

[0061] Figure 3 Schematic diagram of the manufacturing margin of a part of a material to be processed provided in the second embodiment of the present invention. In a specific embodiment, Figure 3 As shown, R can be 2850mm, indicating the curvature radius value of the bending start position, r can be 2805mm, indicating the curvature radius value of the bending start position, and H can be 2mm, indicating the corrugation height value of the material to be processed. Further, the part manufacturing allowance of the material to be processed is obtained, the part manufacturing allowance of the material to be processed is unfolded, and the part manufacturing allowance of the material to be processed is pre-bent using the curvature radius value R of the bending start position, the curvature radius value r of the bending end position, and the corrugation height value H to obtain the material to be processed.

[0062] S230, determining a target bending corrugation curve according to the curvature radius value of the bending start position, the curvature radius value of the bending end position, and the corrugation height value.

[0063] In an optional embodiment of the present invention, determining a target bending corrugation curve based on the curvature radius value of the bending starting position, the curvature radius value of the bending ending position and the corrugation height value may include: calculating a reference arc length value based on the curvature radius value of the bending starting position, the curvature radius value of the bending ending position and the corrugation height value; determining a first arc length value and a second arc length value based on the reference arc length value when the corrugation height value reaches a basic corrugation height threshold; determining a first arc radius value and a second arc radius value based on the first arc length value and the second arc length value; and drawing the target bending corrugation curve based on the first arc radius value and the second arc radius value.

[0064] Among them, the reference arc length value can be an arc length value used to represent a reference corrugated surface. The basic corrugation height threshold can be an indicator data used to determine whether the corrugation height meets the expansion requirements. Optionally, the value of the basic corrugation height threshold can be set according to actual needs, such as being set to 1, 2 or 3 mm, etc. The embodiment of the present invention does not limit the specific numerical value of the basic corrugation height threshold. The first arc length value can be used to represent the arc length of a corrugated convex surface whose bending direction is opposite to the corrugation direction. The second arc length value is used to represent the arc length of a corrugated concave surface whose bending direction is the same as the corrugation direction. The first arc radius value can be a curvature radius value used to represent a corrugated convex surface whose bending direction is opposite to the corrugation direction. The second arc radius value can be a curvature radius value used to represent a corrugated concave surface whose bending direction is the same as the corrugation direction.

[0065] Since the target corrugated surface is composed of a corrugated convex surface and a corrugated concave surface, it is easy to understand that the target corrugated curve of the target corrugated surface at any curvature radius can be obtained by connecting two arcs, that is, the first arc obtained by the first arc radius value and the second arc obtained by the second arc radius value. Therefore, the reference arc length value can be obtained by calculating the curvature radius value of the bending starting position, the curvature radius value of the bending end position and the corrugation height value obtained in the above steps. When the corrugation height value reaches the basic corrugation height threshold, the first arc length value and the second arc length value are determined. It should be noted that since the corrugation needs to be unfolded during the pre-forming bending process in the subsequent steps, in order to optimize the corrugation compensation effect and facilitate the manufacturing of the laying tooling and the laying effect, the corrugations at the densely corrugated areas are relatively gentle. Therefore, the first arc length value and the second arc length value are taken according to the principle that the former takes a smaller value and the latter takes a larger value. Furthermore, the first arc radius value and the second arc radius value may be obtained according to the first arc length value and the second arc length value, and thus the target bending corrugation curve may be drawn according to the first arc radius value and the second arc radius value.

[0066] In an optional embodiment of the present invention, determining the first arc length value and the second arc length value according to the reference arc length value may include:

[0067] The first arc length value and the second arc length value are determined based on the following formula:

[0068]

[0069] Among them, H represents the corrugation height value, H1 represents the corrugation height value at the first arc; H2 represents the corrugation height value at the second arc, L1 represents the first arc length value, L2 represents the second arc length value, R represents the curvature radius value of the bending starting position, and r represents the curvature radius value of the bending end position.

[0070] Correspondingly, when the corrugation height value reaches the basic corrugation height threshold, the corrugation height value, the curvature radius value of the bending starting position and the curvature radius value of the bending ending position can be calculated to obtain a reference arc length value, and then the first arc length value and the second arc length value can be obtained based on the reference arc length value.

[0071] In an optional embodiment of the present invention, determining the first arc radius value and the second arc radius value according to the first arc length value and the second arc length value may include:

[0072] The first arc radius value and the second arc radius value are determined based on the following formula:

[0073]

[0074]

[0075]

[0076] Among them, L1 represents the first arc length value, L2 represents the second arc length value, R represents the curvature radius value of the bending starting position, r represents the curvature radius value of the bending ending position, X1 represents the first arc radius value, and X2 represents the second arc radius value.

[0077] Furthermore, the first arc length value and the second arc length value obtained in the above steps can be substituted into the formula to obtain the first arc radius value and the second arc radius value, so that the target bending corrugation curve can be drawn according to the first arc radius value and the second arc radius value.

[0078] Figure 4 is a schematic diagram of a corrugated surface provided in the second embodiment of the present invention, Figure 5 is a schematic diagram of another corrugated surface provided in the second embodiment of the present invention. In a specific embodiment, Figure 4 and Figure 5As shown, the target bending corrugation curve M can be composed of the first arc l1 and the second arc l2. The corrugation height value H can be composed of the corrugation height value H1 of the first arc l1 and the corrugation height value H2 of the second arc l2. If the corrugation height value H is 2mm, the curvature radius value R of the bending start position is 2850mm, and the curvature radius value r of the bending end position is 2805mm, then H, R and r can be substituted into the formula, and the reference arc length value M can be obtained by calculation as 11.3mm. Further, when the corrugation height value reaches the basic corrugation height threshold, the first arc length value L1 and the second arc length value L2 are obtained according to the principle that the first arc length value L1 takes a smaller value and the second arc length value L2 takes a larger value. Exemplarily, assuming that the basic corrugation height threshold can be any value in the range of 2mm-3mm, when the corrugation height value H is 2.12mm, the first arc length value L1 can be 2mm, and the second arc length value L2 can be 10mm.

[0079] Figure 6 is a schematic diagram of a target bending corrugation curve provided by the second embodiment of the present invention. In a specific embodiment, Figure 6 As shown, the target bending corrugation curve M is composed of the first arc l1 and the second arc l2. The first arc length value L1 and the second arc length value L2 obtained in the above steps can be substituted into the formula to obtain the first arc radius value X1 and the second arc radius value X2 at each curvature radius. For example, the first arc radius value X1 at a curvature radius of 2805mm can be 5.65mm, the second arc radius value X2 can be 28.25mm, the first arc radius value X1 at a curvature radius of 2830mm can be 8.46mm, the second arc radius value X2 can be 42.3mm, etc. Further, the target bending corrugation curve M can be obtained by drawing the first arc radius value X1 and the second arc radius value X2 obtained in the above steps. It should be noted that since the length of the corrugation curve at any curvature radius on the reference corrugated surface is equal to the arc length at the curvature radius of the starting position of the bending, l1=L1, l2=L2.

[0080] S240, obtaining a target corrugated surface of the material to be processed according to the target bending corrugation curve.

[0081] In an optional embodiment of the present invention, obtaining the target corrugated surface of the material to be processed according to the target bending corrugation curve may include: generating a reference corrugated surface by fitting and drawing the target bending corrugation curve; performing symmetry processing and array processing on the reference corrugated surface to obtain the target corrugated surface of the material to be processed.

[0082] The reference corrugated surface may be a corrugated surface of unit length, and the target corrugated surface may be a surface composed of a plurality of reference corrugated surfaces of unit length.

[0083] Correspondingly, after obtaining the target bending corrugation curve through the above steps, the reference corrugation surface can be obtained by multi-section surface fitting according to the target bending corrugation curve. Further, the reference corrugation surface is symmetric and arrayed to obtain the target corrugation surface of the material to be processed.

[0084] Optionally, the target corrugated surface is used for laying on the material to be processed to obtain a target pre-laid ply board; the target pre-laid ply board is used for placing in a bending mold for pre-forming and bending processing.

[0085] The target pre-laid laminate may be a pre-laid laminate that has been subjected to a curved surface treatment and has a corrugated curved surface feature. The bending mold may be a mold used for performing a pre-forming bending process on the pre-laid laminate.

[0086] In an embodiment of the present invention, the material to be processed can be automatically laid according to the target corrugated surface to obtain a target pre-laid laminate with corrugated surface features. Furthermore, the target pre-laid laminate with corrugated surface features can be transferred to a bending mold for fixation, and after positioning is completed, a pre-forming bending process can be performed. Exemplarily, the target pre-laid laminate can be pre-formed and bent into an L-shape, a C-shape, or a Z-shape, and the embodiment of the present invention does not specifically limit the shape after the pre-forming bending process.

[0087] Figure 7 is a schematic diagram of an automatic wire-laying pre-laid laminate provided in the second embodiment of the present invention, Figure 8 is a schematic diagram of a preformed part after bending provided in the second embodiment of the present invention. In a specific embodiment, Figure 7 and 8 As shown, the material to be processed can be unfolded to form a laying area with a fan-shaped contour, and the pre-laid ply can be laid in the current area to obtain the target pre-laid ply with corrugated surface features. Furthermore, the target pre-laid ply with corrugated surface features can be transferred to the bending mold for fixation, and the pre-forming bending process can be performed after the positioning is completed.

[0088] Fig. 9 Schematic diagram of a composite material arc-shaped part provided in the second embodiment of the present invention. In a specific embodiment, the material to be processed can be a composite material arc-shaped part for forming a fiber stack in any direction, and the inner arc side needs to be preformed and bent, such as Fig. 9As shown, the composite arc-shaped part can usually be a bulkhead or corner piece part in the aircraft fuselage structure, with an arc in the length direction, a notch on the outer arc side, and a cross section that can be L, C or Z-shaped. Among them, the fiber direction can start as follows: 0° fiber direction along the arc direction, and the ±θ fiber direction at each point can be the 0° fiber direction at that point rotated ±θ along the right-hand coordinate system.

[0089] Fig.10 FIG. 1 is a flow chart of another method for processing a curved surface of another material according to the second embodiment of the present invention, and is described by taking a composite arc material whose inner arc side needs to be bent as an example. Fig.10 As shown, first determine the pre-bending processing parameters, namely the curvature radius value R at the starting position of the bend, the curvature radius value r at the ending position of the bend, and the corrugation height value H, and then pre-bend the part manufacturing allowance of the material to be processed according to the curvature radius value R at the starting position of the bend, the curvature radius value r at the ending position of the bend, and the corrugation height value H to obtain the material to be processed. Further, substitute the curvature radius value R at the starting position of the bend, the curvature radius value r at the ending position of the bend, and the corrugation height value H into the formula to obtain the reference arc length value, namely L1+L2. Among them, L1 is the first arc length value, and L2 is the second arc length value. Further, substitute the first arc length value L1 and the second arc length value L2 into the formula to obtain the first arc radius value and the second arc radius value at different curvature radii. Furthermore, the target corrugation curve can be obtained according to the first arc radius value and the second arc radius value at different curvature radii. It should be noted that the corrugation curve drawn according to the first arc radius value is a curve that describes the convex surface of the corrugation whose bending direction is opposite to the corrugation direction, and the corrugation curve drawn according to the second arc radius value is a curve that describes the concave surface of the corrugation whose bending direction is the same as the corrugation direction.

Fig.12 As shown, it is a corrugated concave surface with the same corrugation direction and bending direction, that is, the corrugated surface is obtained by drawing a corrugated curve according to the radius value of the second arc.

[0092] Furthermore, the material to be processed can be automatically laid according to the target corrugated surface to obtain a target pre-laid laminate with corrugated surface features. The target pre-laid laminate with corrugated surface features is then transferred to a bending mold for fixation, and after positioning is completed, a pre-forming bending process can be performed.
