[0052] like Figure 1 As shown, an embodiment of the present invention provides a hole arrangement design method for a porous part, wherein a porous sector-shaped part is provided with a preset number of hole rows spaced apart in a radial direction, and the hole arrangement design method for a porous part comprises the following steps:

[0053] S1. In the theoretical design drawing, three columns of theoretical hole positions are selected as theoretical reference datum columns. There is a constant relationship between the theoretical reference datum columns and the theoretical contour of the part.

[0054] S2. In the part adjustment profile, according to the constant relationship, complete the creation of three adjustment reference datum columns corresponding to the theoretical reference datum columns;

[0061] On the adjustment hole center curve, the center of an end hole position corresponding to the theoretical reference hole position is used as the end hole reference hole position, and the remaining adjustment hole positions are created on the adjustment hole center curve according to the length ratio relationship to obtain the adjustment reference datum column;

[0062] Repeat the above steps until three adjustment reference datum columns corresponding to the theoretical reference datum columns are created.

[0063] Preferably, the length ratio relationship is Xn=Ln / S, wherein S is the total length of the theoretical hole center curve, and Ln is the length of the distance between the remaining theoretical hole positions and the theoretical reference hole position along the direction of the theoretical hole center curve.

[0064] Preferably, on each row reference curve, the distance between two adjacent adjustment hole positions along the row reference curve direction is Yn=C / Z, wherein C is the total length of the row reference curve, and Z is the preset number of hole position columns.

[0065] Preferably, before step S1, the method further includes the following steps:

[0066] Prepare sample parts according to the theoretical design drawings;

[0067] Weld the sample parts and obtain the experimental parts after cooling;

[0068] Measure the boundary offset between the sample part and the test part;

[0069] Based on the theoretical contour of the part and combined with the boundary offset, the adjusted contour of the part is obtained.

[0070] Preferably, the boundary offset includes an X-direction offset and a Y-direction offset.

[0071] Preferably, taking the theoretical contour of the part as a reference and combining the boundary offset, obtaining the adjusted contour of the part includes the following steps:

[0072] In the theoretical contour of the part, multiple boundary theoretical hole positions are selected as the first reference hole positions, wherein the boundary theoretical hole position center is the theoretical hole position center closest to the boundary of the theoretical contour of the part, and the distance between the boundary theoretical hole position center and the boundary of the theoretical contour of the part is a preset value;

[0073] Taking the XY coordinates of the centers of the theoretical holes of the multiple boundaries as references and combining them with their corresponding boundary offsets, multiple boundary adjustment hole centers are obtained;

[0074] The adjustment contour of the porous part is obtained by taking the centers of the hole positions adjusted by multiple boundaries as the reference and combining the preset values.

[0075] by Figure 2 A certain engine thin plate part (porous fan-shaped part) is shown as an example for explanation. The outline of the porous part is fan-shaped. There are multiple small holes with a diameter of φD (D ranges from 0.5-1.5mm) distributed on the porous fan-shaped part according to a certain rule. The number of holes is about 5000-15000. The small holes form a preset number of hole columns, and the preset number of hole columns are spaced apart along the radial direction. The thickness of the porous fan-shaped part is δ. For ease of understanding and clear expression of the drawings, a smaller number of holes is used for illustration in the attached drawings.

[0076] (1) First, prepare the sample parts according to the theoretical design drawing; for this porous sector-shaped part, Figure 3The four boundary theoretical hole positions shown ("hole 1", "hole 2", "hole 3", "hole 4") and the theoretical contour of the porous part (solid line segments in the figure, including the first boundary 1, the second boundary 2, the third boundary 3 and the fourth boundary 4 respectively) must satisfy the following relationship: the distance dimension from the axis of "hole 2" to the first boundary 1 is V2, the distance dimension from the axis of "hole 1" to the second boundary 2 is V1, the distance dimension from the axis of "hole 1" to the fourth boundary 4 is H1; the distance dimension from the axis of "hole 2" to the fourth boundary 4 is H2; "hole 3" and "hole 1" are symmetrical relative to the midline, and "hole 4" and "hole 2" are symmetrical relative to the midline. The remaining small holes are distributed according to a certain rule within the dotted line range of "hole 1", "hole 2", "hole 3", and "hole 4".

[0077] (2) Weld the sample parts and obtain the experimental parts after cooling; specifically, overlap the two sample parts, put the solder on the contact surface in advance, heat them to a certain temperature in a diffusion welding furnace, and under a certain pressure, diffusion connection occurs on the contact surface of the two sample parts to complete the welding process. After welding, cool and obtain the experimental parts. Contour comparison of the sample parts and the experimental parts Figure 4 As shown, the contour boundary shown by the solid line in the figure is the contour boundary of the sample part, and the contour boundary shown by the dotted line in the figure is the contour boundary of the experimental part. It can be found that, relative to the sample part, the contour boundary of the experimental part obtained after cooling during welding heat treatment shrinks.

[0078] (3) Measure the boundary offset between the sample part and the experimental part; specifically, take the "zero point" as the measurement reference, and the "zero point" of the experimental part coincides with the "zero point" of the sample part. The X-direction offset of "Point 1" is represented by "X1", and the Y-direction offset is represented by "Y1". The X-direction offset difference of "Point 2" is represented by "X2", and the Y-direction offset is represented by "Y2". "Point 3" is a symmetrical point relative to "Point 1", and "Point 4" is a symmetrical point relative to "Point 2". The dimensional deviation of "Point 5" is represented only by the Y-direction offset "Y5". Measure the values ​​of X1, Y1, X2, Y2 and Y5 respectively to obtain the boundary offset.

[0079] (4) Taking the theoretical contour of the part as a reference and combining the boundary offset, the adjusted contour of the part is obtained, which specifically includes the following steps:

[0080] (4-1) In the theoretical contour of the part, multiple boundary theoretical hole positions (i.e., "hole 1", "hole 2", "hole 3", "hole 4") are selected as the first reference hole positions, wherein the boundary theoretical hole position center is the theoretical hole position center closest to the boundary of the theoretical contour of the part, and the distance between the boundary theoretical hole position center and the boundary of the theoretical contour of the part is a preset value (i.e., V1, V2, H1, H2).

[0081] (4-2) Taking the XY coordinates of the centers of the theoretical holes at the boundaries as the reference, respectively combine the corresponding boundary offsets (i.e., X1, Y1, X2, Y2, and Y5), that is, add the X coordinate of the corresponding hole center to its X-direction offset, and add the Y coordinate of the corresponding hole center to its Y-direction offset, to obtain the XY coordinates of the centers of the adjusted holes at the boundaries;

[0082] (4-3) Based on the positions of the centers of multiple boundary adjustment holes and combined with preset values ​​(i.e., V1, V2, H1, H2), the part adjustment contour is obtained. That is, based on the XY coordinates of the boundary adjustment hole center, the corresponding preset values ​​are offset to determine the coordinates of the vertices of the part adjustment contour, and then combined with the curvature shape of each boundary of the part theoretical contour, the XY coordinates of the boundary adjustment hole center are used as the basis for proportional offset to obtain the boundary of the part adjustment contour, and finally the part adjustment contour is obtained. The final determined part adjustment contour is as follows: Figure 5 As shown (the boundary of the adjusted contour of the porous part is the solid line segment shown in the figure).

[0083] (5) In the theoretical design drawing, select three columns of theoretical hole positions as theoretical reference columns (such as Figure 5 As shown, the three columns of theoretical reference datum columns are respectively the left theoretical reference datum column 5, the middle theoretical reference datum column 6 and the right theoretical reference datum column 7), and there is a constant relationship between the theoretical reference datum columns and the theoretical contour of the part; the theoretical contour of the part forms a fan-shaped closed figure, wherein one column of theoretical reference datum columns is located on the symmetry axis of the fan-shaped closed figure (such as the middle theoretical reference datum column 6 in this embodiment), and the other two columns of theoretical reference datum columns (such as the left theoretical reference datum column 5 and the right theoretical reference datum column 7) are located at both ends of the fan-shaped closed figure and the distance between each adjustment hole position and the boundary of the part theoretical contour is a fixed value, that is, the vertical distance between each theoretical hole position on the left theoretical reference datum column 5 and the third boundary 3 is a fixed value, and the vertical distance between each theoretical hole position on the right theoretical reference datum column 7 and the fourth boundary 4 is a fixed value.

[0084] (6) In the part adjustment profile, according to the constant relationship, the creation of three adjustment reference datum columns corresponding to the theoretical reference datum columns is completed; specifically, the following steps are included (hereinafter referred to as Figures 6 to 10 The embodiment shown is used for explanation):

[0085] (6-1) In each theoretical reference column, connect each hole position center of the theoretical reference column to form a theoretical hole center curve 8, and select a hole position center at one end point of the theoretical hole center curve 8 (such as Figure 6 The hole 1 position shown in FIG. 1 is used as the theoretical reference hole position, and the length ratio relationship between the theoretical reference hole position and the remaining theoretical hole positions on the theoretical hole center curve 8 is calculated; the length ratio relationship X n =Ln / S, where S is the total length of the theoretical hole center curve 8, L n The remaining theoretical holes and theoretical reference holes (such as Figure 6 The length of the distance along the direction of the theoretical hole center curve 8 (the hole 1 position shown in FIG).

[0086] (6-2) In the part adjustment profile, determine the two end points to adjust the hole center according to the fixed value (such as Figure 7 The positions of the first endpoint adjustment hole center 9 and the second endpoint adjustment hole center 10) are shown, and the adjustment hole center curve 11 is established;

[0087] (6-3) On the adjustment hole center curve 11, an endpoint hole position center corresponding to the theoretical reference hole position is used as the endpoint reference hole position (such as the first endpoint adjustment hole position center 9), and the remaining adjustment hole positions are created on the adjustment hole center curve 11 according to the length ratio relationship to obtain the adjustment reference datum column.

[0088] (6-4) Repeat the above steps (6-1) to (6-3) until the creation of three adjustment reference columns corresponding to the theoretical reference columns is completed. Figure 5 As shown, the three adjustment reference datum columns are respectively the left adjustment reference datum column 51, the middle adjustment reference datum column 61 and the right adjustment reference datum column 71, wherein the position of the left adjustment reference datum column 51 corresponds to the position of the left theoretical reference datum column 5, the position of the middle adjustment reference datum column 61 corresponds to the position of the middle theoretical reference datum column 6, and the position of the right adjustment reference datum column 71 corresponds to the position of the right theoretical reference datum column 7.

[0089] (7) Figure 8 As shown, a row reference curve 12 is made through the corresponding adjustment hole positions of each adjustment reference reference column, wherein the curvature of the row reference curve 12 is the same as the boundary curvature of the part adjustment contour, that is, the curvature of the row reference curve 12 is consistent with the curvature of the outer edge arc of the fan-shaped closed figure;

[0090] (8) Fig. 9 As shown, on each row reference curve 12, multiple adjustment holes 13 are created at equal intervals to form a preset number of adjustment hole columns. Specifically, on each row reference curve 12, the distance Y between two adjacent adjustment holes 13 along the row reference curve 12 is n =C / Z, where C is the total length of the row reference curve 12 and Z is the preset number of hole position columns. Fig.10 As shown, a hole is made at each adjustment hole position 13 to obtain an adjusted part design drawing.

[0091] Specifically, a script can be designed by programming, and the script can run a cyclic calculation algorithm. The script is run in the corresponding design software to repeat the above steps until each adjustment hole position setting is completed on each row reference curve 12, which significantly improves the design efficiency. The specific computer program and its design principle involved in the script are prior art well known to those skilled in the art, and this application will not repeat them. When the hole position arrangement design method of the porous part provided in this embodiment is run using a corresponding computer program, after the part profile is adjusted, the hole positions of all small holes can be automatically arranged, thereby improving the small hole arrangement design efficiency and shortening the development cycle of the porous sector-shaped part.

[0092] (9) Cut the parts according to the adjusted part design drawing obtained in step (8), and punch holes according to the positions corresponding to the positions of the adjustment holes 13 to obtain the adjusted sample parts, weld the adjusted sample parts, and obtain the adjusted experimental parts after cooling. The preparation process of the adjusted experimental parts is the same as the above step (2). Then measure the contour deviation value of the adjusted experimental parts relative to the theoretical contour of the parts, as well as the deviation values ​​of the positions of the holes. If the deviation values ​​meet the design requirements, the parts are manufactured and mass-produced according to the corresponding part adjustment contour and hole positions. As long as the contour size and welding process parameters of the parts are consistent, the outer contour size changes of the porous fan-shaped parts after mass production are basically consistent. If the deviation value does not meet the design requirements, repeat steps (4) to (8) again, and use a deviation value different from the last adjustment to adjust the part adjustment contour again until the deviation value meets the design requirements.
