Description

Technical Field

[0001] The invention relates to the field of punching round blanks, and in particular to a method and system for punching round blanks and arranging plates. Background Art

[0002] In the key stamping process of existing pulleys, steel coils need to be blanked into round sheets before stretching. Stamping and blanking layout usually requires operators to use drawing software to draw 1:1 according to the combination of multiple parameters of the round sheet, and use the interlocking layout principle to draw the sample layout according to the optimal solution for the material utilization of the round sheet.

[0003] This existing technical solution, on the one hand, is subject to frequent fluctuations in product order requirements. Once the highest utilization solution for a specific product diameter is drawn, it often fails to meet the steel mill's minimum stock width. This necessitates sequentially laying out blanks for different product diameters within a specific coil width, which is labor-intensive. Furthermore, multiple different blanking layout schemes exist for specific stock widths and diameters. When drawing the layout in drawing software based on the principle of interlocking circular sheets, manual adjustments based on the drawing software diagram are required to avoid uneven layouts that affect the normal operation of the feed and deflection equipment. This requires multiple drawing software adjustments, which is labor-intensive. After completing the layout in the drawing software, the deflection dimensions and feed dimensions must be annotated in the drawing software. Furthermore, the blanking layout process can be completed by searching for recommended deflection speeds and feed speeds for different stock thicknesses provided by the blanking equipment manufacturer and summarizing them in a blanking layout program chart. Due to frequent fluctuations in product demand and the wide variety of products requiring layouts for different thicknesses and diameters, errors in the layout software can damage the equipment and molds, impacting the product production cycle and reducing production efficiency.

[0004] The purpose of the present invention is to design a method and system for blanking and arranging round blanks in order to solve the above problems in the prior art. Summary of the Invention

[0051] In order to facilitate understanding by those skilled in the art, the present invention is now described in further detail with reference to the following examples:

[0052] refer to Figure 1 , a method for blanking and arranging round blanks by punching,

[0053] This example is used to calculate and design an optimal solution for nested circular blanking, automating the blanking and generation of blanking arrangements for punched circular blanks. Nested circular blanking means that after several circular blanks are laid out, the distance between any two adjacent circles is the same, and the circular blanks are distributed on a steel coil in a rectangular shape.

[0054] The following steps are involved:

[0055] S1, generating or pre-storing a stamping parameter relationship table regarding material type, material thickness, overlap value, yaw speed, and feed speed, wherein the overlap value is obtained according to the stamping process and mold design specifications, and the yaw speed and feed speed are obtained according to the recommended values ​​of the stamping equipment based on the material type and material thickness;

[0056] In this step, the material type and thickness can be saved in advance according to the actual material type and specifications. Figure 2 The cell ranges in the first and second columns of the table shown.

[0057] The overlap value is determined by finding the minimum overlap value corresponding to different material thicknesses based on the stamping process and mold design specifications, and the corresponding cell area in the third column of the table is pre-filled.

[0058] The equipment supplier provides recommended yaw and feed speeds for different materials and thicknesses based on the yaw equipment's structural strength, servo parameters, and other factors. These speeds should be pre-populated in the fourth and fifth columns of the table.

[0059] This step finally results in Figure 2 As shown in the table, in the subsequent steps, you only need to obtain the type of material to be stamped and the thickness of the material to be stamped, and then you can match the corresponding data in the table according to the type of material to be stamped and the thickness of the material to be stamped, and quickly get the corresponding overlap value, yaw speed, feeding speed, etc., which reduces the operator's work of looking up tables, matching, etc., and improves efficiency.

[0060] S2, obtaining the type and thickness of the material to be stamped, and matching and outputting the corresponding overlap value T to be stamped, the yaw speed to be stamped, and the feed speed to be stamped from the stamping parameter relationship according to the type and thickness of the material to be stamped;

[0061] S3, obtain the diameter d of the sheet to be punched, calculate the yaw distance parameter A and the yaw distance parameter B according to the diameter d of the sheet to be punched and the overlap value T to be punched, wherein the overlap value T to be punched is the distance between two circular sheets, the yaw distance parameter A is the length of the distance between the center points of three consecutive circular sheets in the feeding direction corresponding to the feeding direction, and the yaw distance parameter A is the length of the distance between the center points of two adjacent circular sheets in the feeding direction corresponding to the feeding direction;

[0062] In this embodiment, reference Figure 3 The diameter of the blank to be punched refers to the diameter of the round blank formed after punching, and the overlap value T to be punched refers to the distance between the two punched blanks on the steel coil. Figure 4 The yaw distance parameter A is the distance between the centers of the 3rd, 4th, and 5th consecutive circular pieces in the feeding direction (transverse direction), which is the sum of the diameters d of the two pieces to be punched and the overlap values ​​T of the two pieces to be punched. The yaw distance parameter B is the transverse component of the distance between the centers of two adjacent circles, for example Figure 4 The distance between the centers of the first and second circles is a very similar component, which is the sum of the diameter d of the blank to be punched and the overlap value T to be punched, that is, A / 2.

[0063] Furthermore, the calculation of the swing distance parameter A according to the diameter d of the sheet to be punched and the overlap value T to be punched includes:

[0064] According to the diameter d of the blank to be punched, the overlap value T to be punched, and the geometric relationship between the circles in the blanking arrangement of the punched circular blank, the runout distance parameter A is calculated according to the following formula:

[0065]

[0066] Furthermore, the yaw distance parameter B=the yaw distance parameter A / 2.

[0067] refer to Figure 4In order to calculate the deflection distance parameter B or the deflection distance parameter A, we can take the right triangle where the center distance of two adjacent circular pieces in two different columns is located for calculation. According to the Pythagorean theorem, we can get Then, based on the relationship between A and B, B can be calculated.

[0068] S4, taking the highest material utilization rate in the feeding direction as the case, calculate the feeding length C to be punched according to the diameter d of the sheet to be punched and the overlap value T to be punched. The feeding length C to be punched is the length of each feeding of the stamping equipment in the direction perpendicular to the feeding direction;

[0069] In this step, according to the principle of interlocking circular sheets and arranging plates, the material utilization rate is highest when the sheet spacing in the feeding direction is the overlapping value.

[0070] Furthermore, in the case of the highest material utilization rate in the feeding direction, the feeding length C to be punched is calculated according to the diameter d of the sheet to be punched and the overlap value T to be punched, including:

[0071] According to the principle of interlocking circular sheets, the material utilization rate is highest when the sheet spacing in the feeding direction is equal to the overlap value T to be punched.

[0072] The length of the material to be punched C = (diameter of the sheet d + overlap value T) / 2.

[0073] The feed length C to be punched is the distance the coil is moved by the yaw device each time. This is the distance required to move from one circular sheet to the next within the same circle. Based on geometric relationships, the feed length C to be punched is (sheet diameter d + overlap value T) / 2.

[0074] S5, obtaining the width of the steel coil, and calculating the odd and even deflection times D1 and E1 under a symmetrical blanking distribution according to the feed length C, the steel coil width, the diameter d of the blank to be punched, and the deflection distance parameter A, and calculating the odd and even deflection times D2 and E2 under an asymmetrical blanking distribution;

[0075] Furthermore,

[0076]

[0077] , wherein the blanking reserve deflection cut-off value is obtained by the blanking reserve recommended value of the stamping equipment;

[0078] The number of even-numbered deflections E1 = the number of odd-numbered deflections D1 - 1.

[0079] Furthermore,

[0080]

[0081] Wherein, the blanking reserve deflection cut-off value is obtained from the blanking reserve recommended value of the stamping equipment;

[0082] The number of even-numbered deflections E2 = the number of odd-numbered deflections D2 - 1.

[0083] In this step, due to the influence of the width of the steel coil, the diameter of the sheet and the overlap value, there will be two modes of arrangement of the round sheets. One is the asymmetric arrangement along the center of the material width. Figure 4 The second is the symmetrical arrangement along the width of the material, which is defined as follows: Figure 5 The skew blanking arrangement shown.

[0084] The formula for calculating the number of slews D1 for asymmetric slew blanking is as shown above. The initial coil positioning and installation error and the slew cutoff value for blanking at the other end of the coil width are determined by the slew equipment and provided by the equipment supplier. Subtracting 1 from the formula indicates asymmetric blanking. The entire formula is rounded down to the nearest integer using the INT command. INT stands for rounding command.

[0085] The calculation formula for the symmetrical oscillating blanking arrangement - the oscillating number of times D2 can be oscillated is as above, and the relevant meaning of the formula is the same as the asymmetrical oscillating blanking arrangement - the oscillating number of times D1 can be oscillated.

[0086] S6, calculating the material utilization rate under symmetrical blanking distribution and the material utilization rate under asymmetrical blanking distribution, and selecting the blanking distribution method corresponding to the maximum value within the theoretical maximum material utilization rate for panel arrangement.

[0087] Furthermore, both the symmetrical blanking distribution and the asymmetrical blanking distribution are arranged in a pattern of interlocking round pieces. The symmetrical blanking distribution is a distribution pattern that is symmetrical about the center of the material width, and the asymmetrical blanking distribution is a distribution pattern that is asymmetrical about the center of the material width.

[0088] Furthermore,

[0089]

[0090] Calculations reveal the utilization rates of the two blanking distributions. This utilization rate can be used to analyze which distribution is optimal. Furthermore, 0.85 represents the theoretical maximum material utilization rate for a circular blank arrangement. Therefore, it is necessary to determine which utilization rate is less than 0.85 and is the maximum.

[0091] In this embodiment, the theoretical maximum material utilization rate is set according to the conventional blanking of the pulley. According to the conventional size and shape of the pulley, it is most appropriate to set it to 0.85. When the blanking size is very small, such as the blanking diameter is 3 and the thickness is 1.5, this unconventional pulley blanking will have a utilization rate of more than 85%, but it is obvious that this utilization rate is not applicable to the pulley.

[0092] Furthermore, the blanking distribution method corresponding to the maximum value within the theoretical maximum material utilization rate is selected for panel arrangement, including:

[0093] S7, correcting the selected blanking distribution mode to the middle of the steel coil, and outputting the corrected blanking mode.

[0094] In step S6, according to theoretical calculation, if the cutter on the steel coil drops material from left to right, if the drop distribution pattern is from the left side of the steel coil, that is, the feed side, the plate arrangement starts immediately. In this case, the distance between the feed side and the plate arrangement may be very short, while the distance between the discharge side and the plate arrangement may be very long. Figure 4 In this case, the stress on the blanking blade will be concentrated on the left side, which will be subjected to greater stress and have a shorter service life. Therefore, step S7 is further added after step S6.

[0095] Specifically, the blanking distribution and the distance between the two ends of the coil are obtained, and then the blanking distribution is adjusted to be the same as the distance between the two ends of the coil. This can be calculated using the following formula: Adjusted blanking distribution and distance between the two ends of the coil = Swing distance parameter A + (Steel coil width - (Swing distance parameter A * Swing number of times D1 is allowed) - Swing distance parameter B - Sheet diameter - Initial coil positioning and installation error - Blanking reserved swing cutoff value) / (Swing number of times D1 is allowed + 0.5). Figure 4 The distribution shown is adjusted as follows Figure 6 shown.

[0096] Specific implementation (unit: mm):

[0097] S1, generate a stamping parameter relationship table.

[0098] S2, obtain the type of the material to be stamped as SPHE, the thickness of the material to be stamped as 3.5, and according to the relationship table, obtain the overlap value to be stamped T = 3.0, the yaw speed to be stamped = 1400, and the feeding speed to be stamped = 280.

[0099] S3, the diameter of the sheet to be punched is obtained as d=132, and according to the formula provided in this step, the deflection distance parameter A=233.8 is calculated, and the deflection distance parameter B=116.9 is calculated.

[0100] S4, calculate and obtain the feeding length C of the punching equipment to be punched = 67.5.

[0101] S5, based on the feeding length C, the width of the steel coil, the diameter of the sheet to be punched d, and the deflection distance parameter A, it is calculated that under the symmetrical blanking distribution, the odd deflection number D1=4, the even deflection number E1=3, and under the asymmetrical blanking distribution, the odd deflection number D2=5, the even deflection number E2=4.

[0102] For S6, under the two blanking distributions, the asymmetric blanking distribution has a total blanking width of 1197.1 and a material utilization ratio of 0.84. The symmetric blanking distribution has a total blanking width of 1314 and a material utilization ratio of 0.92. At this point, the theoretical maximum material utilization ratio is set to 0.85, and the material utilization ratio of the symmetric blanking distribution is greater than 0.85, so the asymmetric blanking distribution is selected.

[0103] S7, corrects the selected blanking distribution mode to the middle of the steel coil, outputs the corrected blanking mode, and the first deflection is 235.56.
