[0004] In the process of realizing this invention, the inventors discovered that in the prior art, during the preforming and bending process of the material to be processed, insufficient allowance at the inner arc can cause bridging and separation, or excessive allowance at the inner arc can cause wrinkles. Summary of the Invention

[0042] Example 1

[0043] Figure 1 This is a flowchart of a material surface processing method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where a reasonable target bending corrugation curve is determined, and the material requiring pre-forming bending is surface-processed according to the target bending corrugation curve. This method can be executed by a material surface processing device, which can be implemented by software and / or hardware, and is generally integrated into an electronic device. This electronic device can be a terminal device or a server device. The embodiments of the present invention do not limit the specific type of electronic device. Correspondingly, as... Figure 1 As shown, the method includes the following operations:

[0044] S110. Obtain the planar contour information of the material to be processed; wherein, the planar contour information of the material to be processed includes the radius of curvature value of the bending start position, the radius of curvature value of the bending end position, and the corrugation height value of the material to be processed.

[0045] The material to be processed can be a material whose inner arc side requires pre-forming bending. The planar contour information can be information representing the basic arc-shaped features of the material to be processed. The radius of curvature at the bending start position can be a radius value representing the starting position of the arc-shaped feature of the material to be processed. Optionally, the radius of curvature at the bending start position can be set according to actual needs, such as 2800, 2850, or 2900 mm, etc. This embodiment of the invention does not limit the specific value of the radius of curvature at the bending start position. The radius of curvature at the bending end position can be a radius value representing the ending position of the arc-shaped feature of the material to be processed. Optionally, the radius of curvature at the bending end position can be set according to actual needs, such as 2805, 2810, or 2815 mm, etc. This embodiment of the invention does not limit the specific value of the radius of curvature at the bending end position. The corrugation height value can be a length value representing the thickness direction of the material to be processed. Optionally, the specific value of the corrugation height can be set according to actual needs, such as 2, 2.5 or 3 mm. This embodiment of the invention does not limit the specific value of the corrugation height.

[0046] In this embodiment of the 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 a partial 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 at the bending start position, the curvature radius value at the bending end position, and the corrugation height value of the material to be processed can be determined according to the material to be processed in order to obtain the target bending corrugation curve. This embodiment of the invention does not specifically limit the material to be processed.

[0047] S120. Determine the target bending wavy curve based on the radius of curvature value at the starting position of the bend, the radius of curvature value at the ending position of the bend, and the wavy height value.

[0048] The target bending wavy curve can be a curve used to describe the wavy characteristics of the material to be processed after preforming bending.

[0049] Furthermore, the target bending corrugated curve can be drawn using the radius of curvature values ​​at the starting and ending points of the bending of the material to be processed, as well as the corrugation height value, so as to generate the target corrugated surface of the material to be processed using the target bending corrugated curve.

[0050] S130. Generate the target corrugated surface of the material to be processed based on the target bent corrugated curve.

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

[0052] Correspondingly, the target wavy surface can be obtained by multi-section surface fitting using the target wavy curve obtained in the above steps, or a reference wavy surface can be obtained by multi-section surface fitting using the target wavy curve obtained in the above steps, and then the reference wavy surface can be symmetrically and arrayed to obtain the target wavy surface. The embodiments of the present invention do not specifically limit the generation method of the target wavy surface.

[0053] Since the target bending corrugated curve is obtained from the corrugation height value described by the curvature radius value at the beginning of the bend and the curvature radius value at the end of the bend, and the target corrugated surface is obtained by fitting the target bending corrugated curve, the material with this corrugated feature has an expandable manufacturing allowance during the subsequent inner arc side preforming bending process. This can solve the problem of unreasonable corrugated surface design applicable to existing materials, improve the rationality of corrugated surface design, and enable the material with corrugated surface feature to fit the mold completely and tightly.

[0054] The technical solution of this embodiment first obtains the planar contour information of the material to be processed, including the radius of curvature at the starting position of the bend, the radius of curvature at the ending position of the bend, and the corrugation height. Then, the target bending corrugation curve is determined based on the radius of curvature at the starting position of the bend, the radius of curvature at the ending position of the bend, and the corrugation height. Finally, the target corrugated surface of the material to be processed is generated based on the target bending corrugated curve. This solves the problem of unreasonable corrugated surface design applicable to materials in the existing system, improves the rationality of corrugated surface design, and enables materials with corrugated surface features to fit the mold completely and tightly.

[0055] Example 2

[0056] Figure 2 This is a flowchart of a material surface processing method provided in Embodiment 2 of the present invention. This embodiment is based on the above embodiment and is further specified. In this embodiment, various specific optional implementation methods for generating the target bent corrugated curve and the target corrugated surface are given. Correspondingly, as... Figure 2 As shown, the method in this embodiment may include:

[0057] S210. Determine the pre-bending processing parameters; wherein, the pre-bending processing parameters include the radius of curvature value at the starting position of the bend, the radius of curvature value at the ending position of the bend, and the corrugation height value.

[0058] S220. The manufacturing allowance of the material to be processed is pre-bent according to the pre-bending processing parameters to obtain the material to be processed.

[0059] The pre-bending parameters can be index parameters used for pre-bending. The manufacturing allowance can be the amount of material retained in the material to be processed, which allows for unfolding, in order to achieve the bending process.

[0060] In this embodiment of the invention, pre-bending parameters are first determined. These parameters can be the radius of curvature at the starting and ending bend positions, or the corrugation height. Further, the manufacturing allowance of the material to be processed is obtained. Using the radius of curvature at the starting and ending bend positions, and the corrugation height, the manufacturing allowance of the material to be processed is pre-bent to obtain the material to be processed.

[0061] Figure 3 This is a schematic diagram of the manufacturing allowance of a part made of a material to be processed, provided in Embodiment 2 of the present invention. In a specific embodiment, such as... Figure 3 As shown, R can be 2850mm, representing the radius of curvature at the starting point of the bend; r can be 2805mm, representing the radius of curvature at the starting point of the bend; and H can be 2mm, representing the corrugation height of the material to be processed. Further, the manufacturing allowance of the material to be processed is obtained. This allowance is then unfolded, and pre-bending is performed using the radius of curvature R at the starting point of the bend, the radius of curvature r at the ending point of the bend, and the corrugation height H, to obtain the material to be processed.

[0062] S230. Determine the target bending wavy curve based on the radius of curvature value at the starting position of the bend, the radius of curvature value at the ending position of the bend, and the wavy height value.

[0063] In an optional embodiment of the present invention, determining the target bent corrugated curve based on the radius of curvature at the bend initiation position, the radius of curvature at the bend end position, and the corrugation height may include: calculating a reference arc length value based on the radius of curvature at the bend initiation position, the radius of curvature at the bend end 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 bent corrugated curve based on the first arc radius value and the second arc radius value.

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

[0065] Since the target corrugated surface is composed of corrugated convex and concave surfaces, it's easy to understand that the target corrugated curve at any radius of curvature can be obtained by connecting two circular arcs: a first arc obtained from the radius of the first arc and a second arc obtained from the radius of the second arc. Therefore, the radius of curvature at the bend start position, the radius of curvature at the bend end position, and the corrugation height obtained in the above steps can be used to calculate the reference arc length. When the corrugation height reaches the basic corrugation height threshold, the first and second arc lengths are determined. It should be noted that since the corrugations need to be unfolded during the subsequent pre-forming bending process, to optimize the corrugation compensation effect and facilitate tooling manufacturing and placement, the corrugations are made smoother in areas of high corrugation density. Therefore, the first and second arc lengths are chosen according to the principle that the former has a smaller value and the latter a larger value. Furthermore, the first arc radius value and the second arc radius value can be obtained based on the first arc length value and the second arc length value, and the target zigzag curve can be drawn based on 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 based on 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] Wherein, 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 radius of curvature value at the starting position of the bend, and r represents the radius of curvature value at the ending position of the bend.

[0070] Correspondingly, when the corrugation height value reaches the basic corrugation height threshold, the corrugation height value, the radius of curvature at the start of the bend, and the radius of curvature at the end of the bend can be used to calculate the reference arc length value. Then, based on the reference arc length value, the first arc length value and the second arc length value can be obtained.

[0071] In an optional embodiment of the present invention, determining the first arc radius value and the second arc radius value based on 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] Wherein, L1 represents the first arc length value, L2 represents the second arc length value, R represents the radius of curvature value at the starting position of the bend, r represents the radius of curvature value at the ending position of the bend, 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 wavy curve can be drawn based on the first arc radius value and the second arc radius value.

[0078] Figure 4 This is a schematic diagram of a corrugated surface provided in Embodiment 2 of the present invention. Figure 5 This is a schematic diagram of another corrugated surface provided in Embodiment 2 of the present invention. In a specific embodiment, such as... Figure 4 and Figure 5As shown, the target bent corrugated curve M can be composed of a first arc l1 and a 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 radius of curvature value R at the starting position of the bend is 2850mm, and the radius of curvature value r at the ending position of the bend is 2805mm, then H, R, and r can be substituted into the formula, and the base arc length value M can be calculated to be 11.3mm. Furthermore, 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 of taking a smaller value for the first arc length value L1 and a larger value for the second arc length value L2. For example, 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 This is a schematic diagram of a target bent corrugated curve provided in Embodiment 2 of the present invention. In a specific embodiment, such as... Figure 6 As shown, the target bent corrugated curve M is composed of a first arc l1 and a 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 radius of curvature. For example, the first arc radius value X1 at a radius of curvature of 2805mm can be 5.65mm, and the second arc radius value X2 can be 28.25mm; the first arc radius value X1 at a radius of curvature of 2830mm can be 8.46mm, and the second arc radius value X2 can be 42.3mm, etc. Furthermore, the target bent corrugated curve M can be drawn based on 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 corrugated curve at any radius of curvature on the reference corrugated surface is equal to the arc length at the radius of curvature at the starting position of the bend, l1 = L1, l2 = L2.

[0080] S240. Obtain the target corrugated surface of the material to be processed based on the target bent corrugated curve.

[0081] In an optional embodiment of the present invention, obtaining the target corrugated surface of the material to be processed based on the target bending corrugated curve may include: generating a reference corrugated surface by fitting and drawing based on the target bending corrugated curve; and 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 can be a corrugated surface of unit length. The target corrugated surface can be a surface composed of multiple reference corrugated surfaces of unit length.

[0083] Accordingly, after obtaining the target bent corrugated curve through the above steps, a reference corrugated surface can be drawn based on the target bent corrugated curve and using multi-section surface fitting. Furthermore, by performing symmetry and array processing on the reference corrugated surface, the target corrugated surface of the material to be processed can be obtained.

[0084] Optionally, the target corrugated surface is used to lay on the material to be processed to obtain a target pre-laid layer; the target pre-laid layer is used to be placed in a bending die for pre-forming bending processing.

[0085] The target pre-laid layer can be a pre-laid layer with a corrugated surface, which has been treated with a curved surface. The bending die can be a die used to pre-form and bend the pre-laid layer.

[0086] In this embodiment of the invention, the material to be processed can be automatically laid according to the target corrugated surface to obtain a target pre-laid layer with corrugated surface features. Further, the target pre-laid layer with corrugated surface features can be transferred to a bending die for fixing, and after positioning, pre-forming bending processing can be performed. For example, the target pre-laid layer can be pre-formed and bent into an L-shape, C-shape, or Z-shape; this embodiment of the invention does not impose specific limitations on the shape after pre-forming bending.

[0087] Figure 7 This is a schematic diagram of an automatic fiber placement pre-laying plate provided in Embodiment 2 of the present invention. Figure 8 This is a schematic diagram of a preformed bent part provided in Embodiment 2 of the present invention. In a specific embodiment, such as... Figure 7 and 8 As shown, the material to be processed can be unfolded to form a fan-shaped laying area. A pre-laid layer is then laid within this area to obtain a target pre-laid layer with corrugated surface features. Furthermore, the target pre-laid layer with corrugated surface features can be transferred to a bending die for fixing. After positioning, pre-forming bending processing can be performed.

[0088] Figure 9 This is a schematic diagram of a composite material arc-shaped part provided in Embodiment 2 of the present invention. In a specific embodiment, the material to be processed can be a composite material arc-shaped part used to form a composite material containing fiber layers in any direction, and the inner arc side needs to be pre-formed and bent, such as... Figure 9As shown, composite curved parts are typically bulkheads or corner pieces in aircraft fuselage structures. They are curved along their length, with notches on the outer curved side, and their cross-sections can be L, C, or Z-shaped. The fiber direction can start at 0° along the arc, and at each point, the ±θ fiber direction can be the 0° fiber direction at that point rotated ±θ along a right-handed coordinate system.

[0089] Figure 10 This is a flowchart of another method for processing curved surfaces of materials according to Embodiment 2 of the present invention. The method is illustrated using a composite arc-shaped material whose inner arc side requires bending as an example. Figure 10 As shown, firstly, the pre-bending parameters are determined, namely the radius of curvature R at the starting bend position, the radius of curvature r at the ending bend position, and the corrugation height H. Then, based on the manufacturing allowance of the material to be processed, pre-bending is performed to obtain the material to be processed. Further, substituting the radius of curvature R at the starting bend position, the radius of curvature r at the ending bend position, and the corrugation height H into the formula, the reference arc length value is obtained, namely L1 + L2. Here, L1 is the first arc length value, and L2 is the second arc length value. Further, substituting the first arc length value L1 and the second arc length value L2 into the formula, the first and second arc radius values ​​at different radii of curvature are obtained. Furthermore, the target corrugated curve can be drawn based on the first and second arc radius values ​​at different radii of curvature. It should be noted that the corrugated curve drawn based on the first arc radius value is the curve describing the corrugated convex surface with the bending direction opposite to the corrugation direction, and the corrugated curve drawn based on the second arc radius value is the curve describing the corrugated concave surface with the bending direction in the same direction as the corrugation direction.

[0090] Figure 11 This is a schematic diagram of a corrugated convex surface with a bending direction opposite to the corrugation direction, provided in Embodiment 2 of the present invention. Figure 12 This is a schematic diagram of a corrugated concave surface with the same bending direction and corrugation direction as provided in Embodiment 2 of the present invention, as shown below. Figure 11 As shown, this is a corrugated convex surface where the corrugation direction is opposite to the bending direction; that is, the corrugated surface is obtained by drawing the corrugated curve based on the radius value of the first arc. For example... Figure 12 As shown, the corrugated concave surface has the same corrugation direction as the bending direction, which is obtained by drawing the corrugation curve based on the second arc radius value.

[0091] Figure 13 This is a schematic diagram of a pre-laid layer with a target corrugated surface feature provided in Embodiment 2 of the present invention, as shown below. Figure 13As shown, the reference corrugated surface is obtained by using multi-section surface fitting based on the target corrugated curve, and the target corrugated surface can be obtained by symmetry and array processing of the reference corrugated surface.

[0092] Furthermore, the material to be processed can be automatically laid according to the target corrugated surface to obtain a target pre-laid layer with corrugated surface features. The target pre-laid layer with corrugated surface features is then transferred to a bending die for fixing. After positioning, pre-forming bending processing can be performed.

[0093] Figure 14 This is a schematic diagram of a pre-formed laminate bent into an L-shape according to Embodiment 2 of the present invention. In a specific embodiment, such as... Figure 14 As shown, the pre-laid layer with the target corrugated surface feature is transferred to the bending die for fixing. After positioning, the inner arc side of the pre-laid layer is bent only once to obtain the L-shaped pre-formed bending part.

[0094] Figure 15 This is a schematic diagram of a pre-formed and C-shaped pre-laid laminate provided in Embodiment 2 of the present invention. In a specific embodiment, such as... Figure 15 As shown, the pre-laid sheet with the target corrugated surface feature is transferred to the bending die for fixing. After positioning, the inner and outer arc sides of the pre-laid sheet are bent simultaneously to obtain a C-shaped pre-formed bent part.

[0095] Figure 16 This is a schematic diagram of a pre-formed laminate bent into a Z-shape according to Embodiment 2 of the present invention. In a specific embodiment, such as... Figure 16 As shown, the pre-laid sheet with the target corrugated surface features is transferred to the bending die for fixing. After positioning, the inner arc side of the pre-laid sheet is first pre-formed and bent. Then, the outer arc side of the pre-laid sheet is bent to obtain the Z-shaped pre-formed bent part.
