Description

Technical Field

[0001] The invention relates to the field of blanking processing of decorative plates, and in particular to a blanking optimization method for linear foamed ceramic decorative plates. Background Art

[0002] Foamed ceramics are a lightweight inorganic building material that can be used for exterior wall insulation boards, interior wall decorative boards, and can also replace gypsum materials for modeling. Conventional foamed ceramics are rectangular and have a certain thickness of plate structure. For general exterior wall insulation boards and interior wall decorative boards, they only need to be cut according to the required specifications. When used for modeling, they usually have a certain line shape, and the changes in the line shape are irregular. During processing, it is necessary to machine and cut the rectangular foamed ceramic plates, carve out the required line shape, and then splice them for use.

[0003] When cutting such linear foamed ceramic plates, carving processing needs to be performed based on the original thickness. Therefore, it is necessary to ensure that the original thickness of the foamed ceramic plates meets the needs. It is necessary to select the foamed ceramic plates with the maximum thickness according to the position of the maximum linear shape. The thicker the original thickness, the higher the corresponding price. Therefore, using thicker foamed ceramic plates will increase the cost on the one hand, and on the other hand, the original thickness of the foamed ceramics required in some areas is relatively thin, and the use of thicker foamed ceramic plates will cause waste of foamed ceramic plates. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a method for optimizing the cutting of linear foamed ceramic decorative panels, which divides the linear foamed ceramic decorative panels to fully utilize the foamed ceramic panels of the same original thickness, thereby reducing material waste and reducing costs.

[0005] A method for optimizing cutting of a linear foamed ceramic decorative board, the method comprising:

[0006] Step 1, preliminarily divide the linear model of the foamed ceramic decorative board, the linear model has an suv three-axis coordinate system, the v axis is the thickness direction of the linear model, and the linear model is unfolded along the surface formed by the u axis and the s axis being perpendicular to each other; the linear model is orthographically projected along the v axis through a rectangular grid to divide the linear model into a number of linear unit modules;

[0007] Step 2, calculate the thickness d of the foamed ceramic plate required for engraving each linear unit module under the initial division scheme, and calculate the difference △d between the thickness D of each linear unit module and the standard foamed ceramic plate, △d=dD;

[0008] If △d≤10mm, the classification meets the requirements; if △d>10mm, proceed to the next step;

[0009] Step 3: Reduce the size of the rectangular grid, and re-divide the linear model of the foamed ceramic decorative board into a number of linear unit modules according to the orthographic projection through the rectangular grid, and re-execute step 2 for judgment.

[0010] Furthermore, the linear model is equally divided into a number of linear units along the s-axis direction, and the width of the orthographic projection of each linear unit along the v-axis is w and the length is L; the length of the rectangular grid is w, and the width of the rectangular grid is x, x<w; the linear unit is divided into a number of linear unit modules along the u-axis direction through the rectangular grid; when the size of the rectangular grid is reduced when executing step 3, the width x of the rectangular grid is gradually reduced to divide the linear unit.

[0011] Furthermore, the length w of the rectangular grid is ≤1500 mm, and the width x of the rectangular grid is between 500-700 mm.

[0012] Furthermore, when the width of the rectangular grid is reduced to 500 mm and Δd>10 mm still exists, the thickness D of the standard foamed ceramic plate is increased, and step 1 is re-executed to divide the grid according to the initial rectangular grid.

[0013] Furthermore, when the thickness D of the standard foamed ceramic plate increases to the maximum and the width of the rectangular grid is reduced to 500, Δd>10 mm still exists, and the initial width parameter of the rectangular grid is adjusted within the range of 300-500 mm, and step 1 is executed again.

[0014] Further, the thickness D of the standard foamed ceramic plate includes different thickness specifications, and the standard foamed ceramic plate with the smallest thickness specification is initially selected.

[0015] Furthermore, the thickness D of the standard foamed ceramic sheet includes different thickness specifications, and the average value of d of the foamed ceramic sheet required for engraving each linear unit module under the initial division scheme is calculated. Initial selection of thickness specifications and The value is closest to the standard foam ceramic board.

[0016] Furthermore, when the orthographic projection division of the linear model of the foamed ceramic decorative board by the rectangular grid satisfies △d≤10mm, the layout is performed within the plane range of the standard foamed ceramic board according to the orthographic projection of each linear unit module in the v-axis direction.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Through the method of the present invention, on the one hand, the linear foamed ceramic decorative panels can be reasonably divided and matched with foamed ceramic panels of corresponding specifications to avoid cutting and processing of the foamed ceramic panels according to the required maximum thickness, thereby reducing waste of panel thickness; in addition, the foamed ceramics can be fully utilized through typesetting, so that the materials are fully utilized and waste is reduced.

[0023] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0024] A method for optimizing cutting of a linear foamed ceramic decorative board, the method comprising:

[0025] Step 1: Import the linear model of the foamed ceramic decorative board into the Rhino software. In this embodiment, the linear model of the foamed ceramic decorative board with a corrugated linear shape is taken as an example. Figure 1-Figure 2 As shown, the linear model has a suv three-axis coordinate system, the v axis is the thickness direction of the linear model, and the linear model is unfolded along the surface formed by the u axis and the s axis being perpendicular to each other, that is, the linear model has a linear shape in the two mutually perpendicular directions of the u axis and the s axis.

[0026] The linear model of the foamed ceramic decorative board is preliminarily divided, and the linear model is divided into several linear unit modules by orthographic projection along the V axis through a rectangular grid. The formation of the rectangular grid is realized by the isocurve function module in the rhino software.

[0027] Specifically, the linear model is equally divided into a number of linear units 1 along the s-axis direction, and the width of the orthographic projection of each linear unit 1 along the v-axis is w and the length is L; the length of the rectangular grid is w, and the width of the rectangular grid is x, x<w; the linear unit is divided into a number of linear unit modules 2 along the u-axis direction through the rectangular grid, such as Figure 3As shown, the length L of a single linear unit 1 is cut by the width of the rectangular grid; when the size of the rectangular grid is reduced during step 3, the width x of the rectangular grid is gradually reduced to divide the linear unit.

[0028] Step 2, calculating the thickness d of the foamed ceramic plate required for engraving each linear unit module under the initial division scheme, the thickness of the foamed ceramic plate required for engraving the linear unit module 2 is d;

[0029] In one embodiment, the length w of the rectangular grid is ≤ 1500 mm, and the width x of the rectangular grid is between 500-700 mm. There are two ways to set the initial width of the rectangular grid. One is that the initial width is the maximum value, that is, 700 mm, and the other is to manually select an intermediate value between 500-700 as the initial width value to avoid selecting 500 mm as the initial width of the rectangular grid for the first time. In this embodiment, a value between 500-700 is manually selected, and the width of the rectangular grid is manually set to 600, and the length of the rectangular grid is 1200 mm.

[0030] exist Figure 3 In the figure, the rectangular grid divides the linear unit 1 into five linear unit modules 2, 5 and the linear unit module 2 along the v-axis. The thicknesses of the foamed ceramic plates required for engraving are d1=93mm, d2=85mm, d3=97mm, d4=89mm and d5=92mm respectively.

[0031] Each linear unit module 2 needs to be obtained by machining and carving from a standard foamed ceramic plate. The standard foamed ceramic plate usually has different specifications, which are specifically reflected in the thickness D of the plate. In this embodiment, three specifications of standard foamed ceramic plates are provided, and the thickness D is 80 mm, 100 mm and 120 mm respectively.

[0032] Calculate the difference △d| between each linear unit module and the thickness D of the standard foamed ceramic plate, |△d=dD;

[0033] If △d≤10mm, the classification meets the requirements;

[0034] If △d>10mm, proceed to the next step;

[0035] When calculating △d for the first time, there are two ways to choose the value of D:

[0036] One is to select a standard foamed ceramic plate with a minimum thickness D, that is, to select a standard foamed ceramic plate with a thickness of 80 mm;

[0037] Another method is to calculate the average value of the thickness d of the foamed ceramic required for processing the linear unit module 2. That is to say Then choose a standard foamed ceramic sheet with a thickness of 100 mm.

[0038] In this embodiment, the standard foamed ceramic with the minimum thickness D is selected as an example, and d1-80=13, d2-80=5, d3-80=17, d4-80=9 and d5-80=12 are calculated respectively. If △d>10mm exists, the next step is executed.

[0039] Step 3

[0040] Step 3: Reduce the size of the rectangular grid, and re-divide the linear model of the foamed ceramic decorative board into a number of linear unit modules according to the orthographic projection through the rectangular grid, and re-execute step 2 for judgment.

[0041] Each time the size of the rectangular grid is reduced, the width of the rectangular grid is specifically reduced, such as by 1 mm each time. For the convenience of explanation, the width of the rectangular grid is reduced by 20 mm each time in this embodiment.

[0042] When the initial rectangular grid does not meet the requirements after division, the width of the rectangular grid becomes 580mm, such as Figure 4 As shown, the number of linear module units 2 has changed from 5 to 6, and the thickness of the foamed ceramic plates required for engraving the 6 linear unit modules 2 separately are d6=87, d7=80, d8=90, d9=83, d10=88, d11=45 respectively; d6-80=7, d7-80=0, d8-80=10, d9-80=3, d10-80=8, d11-80=-35 are calculated respectively; all linear unit modules can be processed by foamed ceramic plates with a thickness of 80 mm.

[0043] In another embodiment, if the width of the rectangular grid is reduced to 500 mm and the thickness of the foamed ceramic is 80 mm, there is still △d>10 mm. At this time, consider increasing the thickness D of the foamed ceramic plate, select a foamed ceramic with a thickness of 100 mm and re-execute step 1. When executing step 1, the width of the rectangular grid is still the maximum value of the initial width, that is, 700 mm, or an intermediate value between 500-700 is artificially selected as the initial width value.

[0044] If the 100mm thick foamed ceramic still does not meet the requirements when the rectangular frame is 500mm, select 120mm thick foamed ceramic as the processing material. At this time, if the width of the rectangular frame is reduced to 500mm, and △d>10mm still exists, consider adjusting the initial width parameter of the rectangular grid within the range of 300-500mm and re-execute step 1.

[0045] When the rectangular grid divides the linear model of the foamed ceramic decorative board into orthographic projections satisfying △d≤10mm, the orthographic projection of each linear unit module in the v-axis direction is laid out within the plane of the standard foamed ceramic board. In this embodiment, the rhino nest plug-in in the rhino software is used to realize the layout of the orthographic projection of each linear unit module in the v-axis direction within the plane of the standard foamed ceramic board.

[0046] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
