Description

Technical Field

[0001] This invention belongs to the field of intelligent mold design technology, specifically relating to a method, storage medium, and device for generating the dimensions and model of a drawing die base. Background Technology

[0002] A drawing die is a stamping tool used to form cup-shaped parts from a flat slab. Drawing dies can produce hollow parts of cylindrical, spherical, conical, box-shaped, stepped, flanged, or other complex shapes. To improve drawing accuracy and quality, and to facilitate unloading after drawing, the upper die of a drawing die is typically designed as a die cavity, and the lower die as a punch. In existing technologies, to simplify and reduce the weight of drawing dies, the upper die holder and the die cavity are usually integrated.

[0003] In existing technologies, the dimensions of the upper die of a drawing die are typically calculated by die designers based on the positional dimensions of the product surface and other mating components. A three-dimensional structural model is then created based on these dimensions, and virtual assembly and operational experiments are conducted to test whether the die can close properly or whether the upper die interferes with other components. If such issues occur, the dimensions of the upper die base need to be adjusted, and a new die model needs to be generated for assembly testing until the upper and lower die bases can close smoothly without interference from other components. Therefore, the design of the upper die base relies on manual calculations, which are often inaccurate. The dimensions of the upper die base require multiple modifications and adjustments, resulting in a complex and inefficient design process. Summary of the Invention

[0026] Example 1

[0027] As attached Figure 1 As shown, the present invention provides a method for generating the dimensions of a drawing die holder, comprising the following steps: obtaining product surface and die parameters, wherein the die parameters include blank line, blank holder flange width, blank holder profile width, ejector pin center X-axis offset, ejector pin center Y-axis offset, guide box width, die height, and die centerline height from the bed;

[0028] The dimensions of the drawing upper die base are obtained based on the mold parameters. These dimensions include the upper die surface, upper die base width (2), upper die base length (1), upper die base bottom height, and upper die base height. The upper die base width (2) and upper die base length (1) are shown in the attached figure. Figure 2 As shown;

[0029] Specifically, the blank holder flange width refers to the minimum width from the edge of the blank holder flange to the blank line; the blank holder profile is the surface on which the blank holder presses the blank against the die, and the blank holder profile width represents the maximum width of this profile; the guide box width represents the width of the mold component - the guide box; the blank holder profile width, blank holder flange width, blank line, and mold stroke are obtained through the product process, the product is the item generated by the mold, the product surface is the profile of the product, and the blank line is the blank edge line before generation; the guide box width and ejector pin spacing are given fixed values ​​based on customer requirements;

[0030] Specifically, the ejector pin offset is determined by the relative positional relationship between the origin of the mold center coordinate system and the center of the bed. The ejector pin offset includes the ejector pin center Y-axis offset and the ejector pin center X-axis offset. The ejector pin center Y-axis offset represents the offset between the origin of the mold center coordinate system and the center of the bed on the Y-axis, and the ejector pin center X-axis offset represents the offset between the origin of the mold center coordinate system and the center of the bed on the X-axis.

[0031] In this embodiment, the height of the bottom surface of the upper mold base is obtained by the difference between the mold height and the height of the mold centerline from the bed; the height 3 of the upper mold base is obtained based on the distance between the bottom surface of the upper mold base and the product surface; the process of obtaining the height of the bottom surface of the upper mold base is as follows: Calculate the intermediate height value m:

[0032] m = H1 - H2

[0033] If m > 100 mm, then the height of the bottom surface of the upper mold base M = m; if m < 100 mm, then the height of the bottom surface of the upper mold base M is between 100 mm and 150 mm.

[0034] Wherein, H1 represents the mold height, and H2 represents the height of the mold centerline from the bed. In this embodiment, the mold height is preferably 1000mm; the height of the mold centerline from the bed is preferably 700mm.

[0035] The mold parameters also include the product surface, the width of the upper mold flange, and the thickness of the upper mold flange. The dimensions of the upper mold base also include the upper mold base profile 6 and the upper mold flange edge. The upper mold base profile 6 is generated based on the product surface; the upper mold flange edge is generated based on the upper mold flange width, the upper mold flange thickness, and the upper mold base length 1. Specifically, the upper mold flange width is the flange width of the upper mold base, and the upper mold flange thickness is the flange thickness of the upper mold base. The upper mold flange width and upper mold flange thickness are set manually. In this embodiment, the upper mold flange thickness is 40mm to 60mm, and the upper mold flange width is 110mm to 150mm.

[0036] In this embodiment, the upper mold base dimensions also include a reinforcing rib distribution diagram. Specifically, the reinforcing rib distribution diagram is obtained according to the distribution principle of the reinforcing ribs 5. The distribution principle is as follows: the spacing between the reinforcing ribs 5 is 250mm to 350mm, and the reinforcing ribs 5 need to avoid the distribution of the machine tool ejector pins. In this embodiment, the reinforcing ribs 5 include main ribs and auxiliary ribs, wherein the thickness of the main ribs is preferably 40mm, and the thickness of the auxiliary ribs is preferably 30mm.

[0037] The width of the pressure ring flange includes the width of the front flange, the width of the rear flange, the width of the right flange, and the width of the left flange. The process of obtaining the upper mold base length 1 and the upper mold base width 2 is as follows:

[0038] The first auxiliary line 11, the second auxiliary line 12, the third auxiliary line 13 and the fourth auxiliary line 14 are obtained based on the billet line; specifically, the first auxiliary line 11 and the third auxiliary line 13 are parallel to the Y-axis in the absolute coordinate system, and the second auxiliary line 12 and the fourth auxiliary line 14 are parallel to the X-axis in the absolute coordinate system.

[0039] As attached Figure 5 As shown, the acquisition process of the first auxiliary line 11, the second auxiliary line 12, the third auxiliary line 13, and the fourth auxiliary line 14 is as follows: The distance from the leftmost point of the billet line to the absolute Y-axis is obtained, and this distance is rounded to the nearest five to obtain the first auxiliary line 11; the distance from the topmost point of the billet line to the absolute Y-axis is obtained, and this distance is rounded to the nearest five to obtain the second auxiliary line 12; the distance from the rightmost point of the billet line to the absolute Y-axis is obtained, and this distance is rounded to the nearest five to obtain the third auxiliary line 13; the distance from the bottommost point of the billet line to the absolute Y-axis is obtained, and this distance is rounded to the nearest five to obtain the fourth auxiliary line 14.

[0040] Specifically, the absolute coordinate system usually represents the original coordinate system in 3D software. Before creating and drawing other parts, the product needs to be imported into the absolute coordinate system, and other parts are drawn and created based on the positional relationship between the product and the absolute coordinate system. The process of rounding to a multiple of 5 is as follows: the Z-value of the lowest point is rounded to a multiple of "5". For example, among the numbers 0 to 5, numbers less than 2.5 become 0 after rounding to a multiple of 5, and numbers greater than or equal to 2.5 become 5 after rounding to a multiple of 5. Among the numbers 5 to 10, numbers less than 7.5 become 5 after rounding to a multiple of 5, and numbers greater than or equal to 7.5 become 10 after rounding to a multiple of 5. For example, coordinate values ​​1 and 2.4 become 0 after rounding to a multiple of 5, coordinate values ​​2.5 and 4 become 5 after rounding to a multiple of 5, coordinate values ​​6 and 7.3 become 5 after rounding to a multiple of 5, and coordinate values ​​7.6 and 9 become 10 after rounding to a multiple of 5. The advantage of using multiples of 5 is that it facilitates measurement by fitters and machining. At the same time, the dimensions of the processed parts are all multiples of 5, making positioning and marking during machining more convenient.

[0041] The first intermediate parameter is obtained based on the first auxiliary line 11, the width of the left flange, the width of the pressure plate, and the X-axis offset of the ejector pin centerline; the third intermediate parameter is obtained based on the third auxiliary line 13, the width of the rear flange, the width of the pressure plate, and the X-axis offset of the ejector pin centerline; the upper mold base length 1 is obtained by adding the first intermediate parameter and the third intermediate parameter.

[0042] The second intermediate parameter is obtained based on the second auxiliary line 12, the width of the front flange, the width of the pressure plate, and the offset of the ejector pin centerline Y-axis; the fourth intermediate parameter is obtained based on the fourth auxiliary line 14, the width of the rear flange, the width of the pressure plate, and the offset of the ejector pin centerline Y-axis; the upper mold base width 2 is obtained by adding the second and fourth intermediate parameters.

[0043] Specifically, the process of obtaining the first intermediate parameter is as follows:

[0045] The second reference variable for calculating the first intermediate parameter is: l2 = D1 + W L +N+K;

In this embodiment, the width of the guide box is preferably 260mm, the distance between the push rods is preferably 150mm, and the width of the pressure profile is preferably 20mm.

[0049] Specifically, the process of obtaining the third intermediate parameter is as follows:

[0050] The first reference variable for calculating the third intermediate parameter:

[0051] The second reference variable for calculating the third intermediate parameter is: r2 = D3 + W R +N+K;

[0052] If the entire top rod avoids the obstacle, when r1 < r2, the third intermediate variable R = r1 + J; when r1 ≥ r2, the third intermediate variable R = r1.

[0053] If the top rod does not avoid the obstacle, the third intermediate variable R = r2;

[0054] Where D3 represents the perpendicular distance from the third auxiliary line to the origin of the absolute coordinate system, W R This indicates the width of the right flange of the pressure ring.

[0055] Specifically, the process of obtaining the second intermediate parameter is as follows:

[0056] The first reference variable for calculating the second intermediate parameter:

[0057] The second reference variable for calculating the second intermediate parameter is: f2 = D2 + W F +N;

[0058] If the entire top rod avoids the obstacle, when f1 < f2, the second intermediate variable F = f1 + J; when f1 ≥ f2, the second intermediate variable F = f1.

[0059] If the top rod does not avoid the obstacle, the second intermediate variable F = f2;

[0060] Wherein, the round() function represents the rounding function, D2 represents the vertical distance from the second auxiliary line to the origin of the absolute coordinate system, and W... F N represents the width of the front flange of the pressure ring, N represents the width of the pressure profile, ΔY represents the Y-axis offset of the ejector pin center, and J represents the ejector pin spacing.

[0061] Specifically, the process of obtaining the fourth intermediate parameter is as follows:

[0062] The first reference variable for calculating the fourth intermediate parameter:

[0063] The second reference variable for calculating the second intermediate parameter is: b2 = D4 + W B +N;

[0064] If the entire top rod avoids the obstacle, when b1 < b2, the second intermediate variable B = b1 + J; when b1 ≥ b2, the second intermediate variable B = b1.

[0065] If the top rod does not avoid the obstacle, the second intermediate variable B = b2;

[0066] Where D4 represents the perpendicular distance from the fourth auxiliary line to the origin of the absolute coordinate system, W R This indicates the width of the rear flange of the pressure ring.

[0067] In this embodiment, whether the top rod avoids an obstacle is a manually set condition, that is, the top rod is set to avoid an obstacle or not avoid an obstacle by human intervention.
