Description

Technical Field

[0001] This invention belongs to the field of intelligent mold design and manufacturing technology, specifically relating to a method for generating mold pressure ring dimensions, a model generation method, and a system. Background Technology

[0002] During the deep drawing process, the flange portion of the product in the deformation zone is susceptible to wrinkling or tearing due to tangential compressive stress, potentially rendering the product unusable or even damaging the die. Therefore, to prevent wrinkling or tearing during deep drawing, a blank holder device is typically used in the design of the drawing die. During die operation, the blank holder firmly presses the product against the die surface, with the flange passing only through the gap between the blank holder and the die surface, preventing instability and ensuring product quality.

[0003] In existing technologies, the design of blank holders is a trial-and-error process. Typically, the dimensions of the blank holder are manually designed, and a 3D structural model is generated based on these dimensions to participate in the virtual assembly and operation of the mold. This process checks whether the blank holder interferes with other components during virtual mold operation. If interference occurs, the blank holder dimensions need to be adjusted, and testing continues until there is no interference. Therefore, the design process for the blank holder dimensions and model is complex and inefficient. Summary of the Invention

R This indicates the width of the right flange of the pressure ring.

[0008] Furthermore, the process of obtaining the second intermediate parameter is as follows: Calculate the first reference variable for the second intermediate parameter: The second reference variable for calculating the second intermediate parameter is: f2 = D2 + W F+N; If the entire top rod avoids the obstacle, when f1 < f2, the second intermediate variable F = f1 + 150mm; when f1 ≥ f2, the second intermediate variable F = f1; if the entire top rod does not avoid the obstacle, the second intermediate variable F = f2; where, the round() function represents the rounding function, D2 represents the vertical distance from the second auxiliary line to the absolute coordinate, W F The width of the front flange of the blank holder is represented by N, the width of the blank holder profile is represented by N, and ΔY is the Y-axis offset of the ejector pin center.

[0011] Furthermore, the process for obtaining the radius of the top rod column is as follows: Obtain the distance d from the bottom surface of the top rod column to the bottom surface of the pressure ring; if d > 90 mm, when the thickness of the auxiliary reinforcement is less than or equal to 30 mm, the radius of the top rod column is taken as 50 mm to 45 mm; when the thickness of the auxiliary reinforcement is greater than 30 mm, the radius of the top rod column is taken as 45 mm to 40 mm; if d ≤ 90 mm, the radius of the top rod column is taken as 40 mm to 35 mm.

By utilizing and calculating the model parameters from multiple perspectives, interference between the pressure ring and other components is minimized. The pressure ring is variable, and for any randomly input model parameters, the corresponding pressure ring size and three-dimensional structural model can be obtained. Any change in any model parameter will generate a pressure ring with a different three-dimensional structure. The size of the pressure ring and the corresponding three-dimensional structural model can be obtained quickly and accurately. Compared with manual design and trial and error, the method described in this solution is simpler, more efficient, and yields a more accurate pressure ring size, thereby achieving the goal of intelligent and efficient design.

[0026] Example 1

[0027] This embodiment provides a method for generating the size of a mold blank holder, including the following steps:

[0028] Step 1: Obtain mold parameters, including parting line 15, blank line, flange width, pressure plate width, ejector pin offset, guide box width, center line distance from mold bed height, ejector pin ejection height, mold stroke, ejector pin position, and reinforcing rib data;

[0029] In this embodiment, the parting line 15, blank line, and mold stroke are obtained through product process, and the product is the item generated by the mold; the width of the blank holder surface, the width of the guide box, and the ejection height of the ejector pin are given fixed values ​​based on the design experience of the mold designer or customer requirements. The blank holder surface is the surface of the die where the blank is pressed against the die by the blank holder ring, and the width of the blank holder surface indicates the maximum width of the surface; the flange width refers to the minimum width from the flange edge of the blank holder ring to the blank line; the reinforcing rib data includes the distribution information and thickness of the reinforcing ribs.

[0030] In this embodiment, 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] Step 2: Generate the blank holder dimensions according to the mold parameters; the blank holder dimensions include the outer flange dimensions, the inner contour of the blank holder, the blank holder height, the radius of the ejector pin 7, the position of the ejector pin 7, the height of the ejector pin 102, and the position of the reinforcing rib.

[0032] In this embodiment, the inner ring contour of the pressure ring is obtained based on the contour of the parting line 15, and the position of the ejector pin is determined based on the position distribution of the ejector pins. The position distribution of the ejector pins is set by the design experience of the mold designer or by the customer. The ejector pin pad is installed on the bottom surface of the ejector pin 7. The position of the reinforcing rib is generated based on the distribution information of the reinforcing rib. The distribution information of the reinforcing rib is usually represented by a reinforcing rib sketch. The reinforcing rib sketch is generated by the mold designer. The standard for drawing the reinforcing rib sketch is that the spacing between the reinforcing ribs is between 250mm and 350mm, and the reinforcing ribs need to avoid the entire ejector pin. The thickness of the reinforcing rib is set by the mold designer or by the customer. In this embodiment, the thickness of the main reinforcing rib is preferably 40mm, and the thickness of the auxiliary reinforcing rib is preferably 30mm.

[0033] In this embodiment, the flange width includes the front flange width 2, the rear flange width 4, the left flange width 1, and the right flange width 3; specifically, the front flange thickness 2 is the minimum distance from the front of the pressure ring flange to the billet line, the rear flange thickness 4 is the minimum distance from the rear of the pressure ring flange to the billet line, the left flange thickness 1 is the minimum distance from the left of the pressure ring flange to the billet line, and the right flange thickness 3 is the minimum distance from the right of the pressure ring flange to the billet line.

[0034] Specifically, 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.

[0035] The process of obtaining the first auxiliary line 11, the second auxiliary line 12, the third auxiliary line 13, and the fourth auxiliary line 14 is as follows: Obtain the distance value from the leftmost point of the billet line to the absolute Y-axis, and then round this distance value to the nearest five to obtain the first auxiliary line 11; Obtain the distance value from the top point of the billet line to the absolute Y-axis, and then round this distance value to the nearest five to obtain the second auxiliary line 12; Obtain the distance value from the rightmost point of the billet line to the absolute Y-axis, and then round this distance value to the nearest five to obtain the third auxiliary line 13; Obtain the distance value from the bottom point of the billet line to the absolute Y-axis, and then round this distance value to the nearest five to obtain the fourth auxiliary line 14.

[0036] Specifically, the process of rounding to the nearest 5 involves rounding the Z-value of the lowest point to a multiple of 5. For example, among numbers 0 to 5, numbers less than 2.5 become 0 after rounding to the nearest 5, and numbers greater than or equal to 2.5 become 5. Among numbers 5 to 10, numbers less than 7.5 become 5 after rounding to the nearest 5, and numbers greater than or equal to 7.5 become 10. For instance, coordinate values ​​1 and 2.4 both become 0 after rounding to the nearest 5, coordinate values ​​2.5 and 4 both become 5, coordinate values ​​6 and 7.3 both become 5, and coordinate values ​​7.6 and 9 both become 10. The advantage of rounding to the nearest 5 is that it facilitates measurement by fitters, and the processed part dimensions are all multiples of 5, making positioning and marking during machining more convenient.

[0037] In this embodiment, the flange outer dimensions of the pressure ring include the flange outer width 5 and the flange outer length 6. The process for obtaining the flange outer dimensions is as follows:

[0038] The first intermediate parameter is obtained based on the first auxiliary line 11, the left flange width 1, the pressure profile width and the X-axis offset of the centerline of the top rod;

[0039] The second intermediate parameter is obtained based on the second auxiliary line 12, the front flange width 4, the pressure profile width, and the Y-axis offset of the top rod centerline.

[0040] The third intermediate parameter is obtained based on the third auxiliary line 13, the rear flange width 2, the pressure profile width, and the X-axis offset of the top rod centerline.

[0041] The fourth intermediate parameter is obtained based on the fourth auxiliary line 14, the rear flange width 3, the pressure profile width, and the Y-axis offset of the top rod centerline.

[0042] The flange outer perimeter length 6 is obtained by adding the first intermediate parameter and the third intermediate parameter; the flange outer perimeter width 5 is obtained by adding the second intermediate parameter and the fourth intermediate parameter. In this embodiment, the flange outer perimeter dimension also includes the flange outer perimeter thickness 16, which is obtained by the mold designer based on design experience or set by the customer. In this embodiment, the flange outer perimeter thickness 16 is preferably 40mm.

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

[0044] The first reference variable for calculating the first intermediate parameter:

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

[0046] If the entire top rod avoids the obstacle, when l1 < l2, the first intermediate variable L = l1 + 150 mm; when l1 ≥ l2, the first intermediate variable L = l1.

[0047] If the top rod does not avoid the obstacle, the first intermediate variable L = l2;

[0048] Where, the `round()` function represents the rounding function, D1 represents the vertical distance from the first auxiliary line 11 to the origin 10 of the absolute coordinate system, and W... L The width of the left flange of the pressure ring is represented by N, the width of the pressure profile is represented by ΔX, the offset of the center of the push rod on the X-axis is represented by K, and the width of the guide box is represented by K. In this embodiment, the width of the guide box is preferably 260mm.

[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 top rod avoids the obstacle, when r1 < r2, the third intermediate variable R = r1 + 150mm; 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 vertical distance from the third auxiliary line 13 to the origin 10 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 is used for clearance, when f1 < f2, the second intermediate variable F = f1 + 150mm; 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] Where, the round() function represents the rounding function, D2 represents the vertical distance from the second auxiliary line 12 to the origin 10 of the absolute coordinate system, and W... F The width of the front flange of the pressure ring is indicated by N, the width of the pressure profile is indicated by N, and the offset of the center of the push rod is indicated by ΔY.

[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 top rod is used for clearance, when b1 < b2, the second intermediate variable B = b1 + 150mm; 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 14 to the origin 10 of the absolute coordinate system, W B 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.

[0068] In this embodiment, the calculation process for the height 102 of the push rod is as follows:

[0069] H1 = h1 - h2 + ST;

[0070] Wherein, H1 represents the ejector pin height, h1 represents the centerline height from the mold bed, h2 represents the ejector pin ejection height, and ST represents the mold stroke. In this embodiment, the centerline height from the mold bed is preferably 700mm; the ejector pin ejection height is preferably 200mm; and the mold stroke is preferably 110mm.

[0071] In this embodiment, the formula for calculating the height 101 of the pressure ring is as follows:

[0072] H2 = h1 - h3 - 40 mm;

[0073] Wherein, H2 represents the height of the pressure ring, h1 represents the height of the center line from the bed, and h3 represents the height of the lower die holder; the preferred height of the lower die holder is 200mm.

[0074] Specifically, the height of the pressure ring is the minimum distance from the bottom surface of the pressure ring flange to the origin 10 of the absolute coordinate system. The top surface of the pressure ring is determined based on the product surface. The height 102 of the ejector pin is the minimum distance from the bottom surface of the ejector pin 7 to the origin 10 of the absolute coordinate system. The absolute coordinate system usually represents the original coordinate system in 3D software. Before creating and drawing other components, the product needs to be imported into the absolute coordinate system, and other components are drawn and created based on the positional relationship between the product and the absolute coordinate system. The height of the lower mold base is specifically the distance from the bottom surface of the lower mold base to the absolute coordinate system. The height of the centerline from the bed and the height of the lower mold base are both obtained through the positional relationship between the product and the absolute coordinate system.

[0075] In this embodiment, the process of obtaining the radius of the push rod 7 is as follows: obtain the distance d from the bottom surface of the push rod 7 to the bottom surface of the pressure ring; specifically, the distance from the bottom surface of the push rod 7 to the bottom surface of the pressure ring is calculated based on the height of the pressure ring and the height 102 of the push rod.

[0076] If d>90mm, when the thickness of the auxiliary reinforcement is less than or equal to 30mm, the radius of the top rod column 7 is taken as 50mm~45mm; when the thickness of the auxiliary reinforcement is greater than 30mm, the radius of the top rod column 7 is taken as 45mm~40mm.

[0077] If d≤90mm, the radius of the top rod column 7 should be 40mm~35mm.
