Description

Technical Field

[0001] This invention relates to the field of automotive mold component inspection technology, and in particular to a method for rapidly generating interference curves for interference inspection of the transfer mold of a car door component mold. Background Technology

[0002] Transfer die interference inspection is a quality control method used in the engineering field to detect collisions or interference between objects. In the current trend, in the automotive parts industry, in order to ensure the safety and efficiency of stamping production lines, its application aims to ensure that transfer dies avoid mechanical collisions and safety risks during movement.

[0003] In the interference inspection of transfer molds in the automotive parts industry, the safety and efficiency of the stamping production line are mainly ensured through a combination of static and dynamic techniques. The core method is interference inspection, which involves analyzing the interference curve. For example:

[0004] In multi-station mold design, the most important part is the overall layout design. Considering the overall feasibility, it is necessary to ensure that each mold in the multi-station meets the interference curve requirements.

[0005] Multi-station molds are several sets of single-sequence molds installed together as one unit, and the working process is completed simultaneously on one machine tool. Through different performance characteristics of the equipment, the multi-station molds achieve a reasonable movement process.

[0006] Multi-station molds are commonly used for parts that are relatively flat and slender. Multi-station molds have significantly improved production efficiency compared to single-sequence molds. Given the dual requirements of product quality and efficiency, multi-station molds will be a development trend in the mold industry.

[0007] Therefore, there is an urgent need to perform interference checks on multi-station molds, and the accurate and rapid generation of interference curves has become a necessary condition.

[0008] Based on the above, the use of interference curves in the interference inspection of transmission molds can automatically analyze and simulate the motion of stamped parts in simulation software. Through stamping process analysis, the stamped parts and molds can be optimized, which improves the cycle time of the automated line and saves mold debugging time.

[0009] More and more automobile manufacturers are adopting high-speed automated stamping production lines to meet the needs of rapid production. However, improving the production cycle of stamped parts and upgrading automated production lines requires considering the interference between the end effector, the stamped parts, and the upper and lower dies during the handling of stamped parts. This is crucial. Specifically, checking for these interferences during the product design and die design stages and identifying them in advance to shorten the die debugging time on the automated line is an important step in solving the problem. Obviously, if interference curves can be generated quickly and accurately, many aspects can be optimized.

[0010] To further explain, in the existing technology, such as the Chinese invention patent, authorized announcement number CN102646142B, patent title "A Simulation-Aided Design Method for an Automated End Capturing Device for Stamping", its technical solution can quickly determine the arrangement of the secondary and tertiary linkages of the end capturing device for stamping workpieces through this convenient and reliable simulation method, and quickly determine its spatial posture and length, which can significantly improve the quality of the end capturing device and the efficiency of design and manufacturing; however, its core technical route directly acts on the end capturing device end, the interference inspection and processing coverage is limited, and the scope of application is also limited. Summary of the Invention

[0011] The present invention aims to solve the technical problem of the lack of existing technology for interference inspection of the transfer mold of car door parts, and to achieve accurate and rapid acquisition of interference curves for inspection. It provides a method for rapid generation of interference curves for interference inspection of the transfer mold of car door parts.

[0012] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0013] A method for rapidly generating interference curves for interference inspection of car door component mold transfer molds includes:

[0014] Step S101: Before drawing the 3D interference curve, four stroke parameters and their corresponding values ​​are preset.

[0015] The four travel parameters are as follows:

[0016] The stroke of the slide block on the punch press, the forward feed stroke of the X-axis, the opening and closing stroke of the Y-axis, and the lifting stroke of the Z-axis;

[0017] Step S102: The four stroke parameters are converted by the action angle to obtain the angle ratio value of each 1mm formation.

[0018] A complete process of changing the angle of an action can be expressed as follows: a complete action is defined as a 360-degree change in angle.

[0019] A complete action includes: the corresponding conversion of two sets of forward feed shaft strokes, two sets of opening and closing shaft strokes, and two sets of lifting shaft strokes;

[0020] Step S103: Integerize the angle ratio values ​​corresponding to the forward feed shaft stroke, the two sets of opening and closing shaft strokes and the two sets of lifting shaft strokes, and draw an angle diagram.

[0021] The intersection angle needs to be preset in the angle diagram, and the intersection angle is no greater than 30 degrees;

[0022] Step S104: Based on the angle diagram, use AutoCAD software to draw a block diagram that corresponds to the angle diagram;

[0023] The process of drawing the block diagram is as follows:

[0024] Step S1041: Based on the value of the slide stroke on the punch press as the height and the 360-degree angle as the width, first construct a box, and divide the box into two equal blocks at the top and bottom, and four equal blocks on the left and right.

[0025] Step S1042: Set the middle node and edge node after the box is divided into regions, and use the AutoCAD cloud line command and SPLINE function to draw the curves of the middle node and edge node.

[0026] Step S1043: Use the TRIM function in the AutoCAD trim command to index the curve and leave only the line. Use the MIRROR command to mirror the curve as a curve segment.

[0027] Step S105: Place the line segments of the slide stroke curve of the punch press to the corresponding positions and draw: forward feed curve, opening and closing curve, and lifting curve. The obtained forward feed curve, opening and closing curve, and lifting curve are superimposed on the block diagram to obtain the running curve diagram.

[0028] Step S106: Draw an interference curve based on the running curve graph, the interference curve including a first interference curve and a second interference curve;

[0029] Step S107: In the Excel software, establish the parameters for creating the interference curve, automatically round off the values, and calculate the parameters for creating the interference curve.

[0030] Generate 3D interference curves in the CATIA-V5 interface.

[0031] Furthermore, the process of obtaining the first interference curve by drawing the interference curve based on the aforementioned running curve diagram is as follows:

[0032] Step S1061: The relative positions (SS1) of the slide stroke and forward stroke on the punch press during operation are obtained by measuring the running curve.

[0033] The relative positions of the slide block and the forward stroke during the operation of the punch press can be measured using the aforementioned operating curve.

[0034] Take one data point every 2.5 or 3 measurements, and keep the angle consistent for all subsequent measurements.

[0035] Based on the measured data, the intersection points of the punch press slide and the forward stroke can be plotted. Connecting each point with a cloud-shaped line will yield the curve of the punch press slide and the forward stroke line segment.

[0036] After removing the extra auxiliary lines, you can obtain the line graph of the punch press slide and the forward stroke line segment curve.

[0037] Step S1062: The corresponding positions of the slide stroke and opening / closing stroke on the punch press during operation are obtained by measuring the running curve.

[0038] Measure one point every 2.5 units. The more measurement points, the more accurate the final interference curve will be. Find the intersection point of the punch press slide and the opening and closing stroke, and connect the points with a cloud-shaped line to obtain the line segment curve of the punch press slide stroke and the opening and closing stroke.

[0039] After removing the extra auxiliary lines, you can obtain the line graphics of the punch press slide and the opening and closing stroke line segment curves.

[0040] Step S1063, curve merging: After merging the line graphs of the punch slide and the forward stroke line segment curve and the line graphs of the punch slide and the opening and closing stroke line segment curve, the first interference curve diagram can be obtained.

[0041] Furthermore, the process of obtaining the first interference curve by drawing the interference curve based on the aforementioned running curve diagram is as follows:

[0042] Step S1064: The corresponding positions during the forward and lifting strokes can be measured from the running curve diagram.

[0043] By measuring one point for every two measurements, the intersection point of the forward stroke and the lifting stroke can be obtained. Connecting these points with a cloud-shaped line will yield the curve of the forward stroke and the lifting stroke.

[0044] After removing the extra auxiliary lines, you can obtain the line graph of the forward stroke and lifting stroke line segment curve (S300);

[0045] Step S1065: The corresponding positions of the forward feed stroke and the opening and closing stroke during operation can be measured from the running curve diagram;

[0046] By measuring one point for every two measurements, the intersection point of the forward feed stroke and the opening and closing stroke can be obtained. Connecting each point with a cloud-shaped line will yield the curve of the forward feed stroke and the opening and closing stroke.

[0047] After removing the extra auxiliary lines, you can obtain the line graph of the forward stroke and the opening and closing stroke line segments.

[0048] Step S1066: After aligning the line graphs of the forward stroke and lifting stroke curves and the line graphs of the forward stroke and opening / closing stroke curves, the second interference curve graph can be obtained.

[0049] Alternatively, in the Excel software tool, a measurement point can be created for every 1 degree.

[0050] The present invention has the following beneficial effects:

[0051] Interference curves can be used in simulation software to automatically analyze and simulate the motion of stamped parts. Through stamping process analysis, the stamped parts and dies are optimized, improving the cycle time of the automated line and saving die debugging time. A measuring point is created for every 1 degree (compared to creating a measuring point for every 2 degrees when manually plotting, the accuracy of the interference curve is doubled; the accuracy of table-based measuring points can be further improved).

[0052] Furthermore, the principle of generating the local interference curve can be implemented in commonly used software such as Excel using VBA programming to calculate and generate the interference curve measurement points in stages, which is more efficient and convenient.

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. It should be noted that, for ease of description, in this application, "left side" is referred to as "first end", "right side" as "second end", "upper side" as "first end", and "lower side" as "second end" in the current view. The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.

[0067] This invention addresses the technical problem of the lack of existing technologies for accurately and quickly obtaining interference curves for interference inspection of the transfer mold of automotive door components. It provides a method for rapidly generating interference curves for interference inspection of the transfer mold of automotive door components, including:

[0068] Step S101: Before drawing the 3D interference curve, four stroke parameters and their corresponding values ​​need to be set in advance.

[0069] The four travel parameters are as follows:

[0070] The stroke of the slide block on the punch press, the forward feed stroke of the X-axis, the opening and closing stroke of the Y-axis, and the lifting stroke of the Z-axis;

[0071] In the embodiments of this solution, as shown in the appendix Figure 1 As shown, the four travel parameters and their corresponding values ​​are set as follows:

[0072] Slide travel on the punch press: 800mm;

[0073] Front feed axis travel (X-axis): 1200mm;

[0074] Opening / closing axis travel (Y-axis): 380mm;

[0075] Lifting shaft travel (Z-axis): 170mm;

[0076] Step S102: Obtain the angle ratio value of each 1mm formation by converting the four stroke parameters into motion angles;

[0077] A complete process of changing the angle of an action can be expressed as follows: a complete action is defined as a 360-degree change in angle.

[0078] A complete motion consists of the corresponding conversion of two sets of forward feed shaft strokes, two sets of opening and closing shaft strokes, and two sets of lifting shaft strokes.

[0079] The calculations are performed using the values ​​provided in this embodiment:

[0080] Specifically: 1200mm×2+380mm×2+170mm×2=3500mm, with the movement distributed in a 360-degree range, meaning each 1mm is 0.10285 degrees;

[0081] Furthermore, the corresponding angular proportions for each formation are obtained as follows:

[0082] The angle occupied by the front feed shaft stroke = 1200 × 0.10285 = 123.42 degrees;

[0083] The angle occupied by the opening and closing shaft stroke = 380 × 0.10285 = 39.083 degrees;

[0084] The angle occupied by the lifting shaft travel = 170 × 0.10285 = 17.484 degrees;

[0085] Step S103: Based on a 180-degree range of motion, the angle ratio values ​​corresponding to the forward feed shaft stroke, the two sets of opening and closing shaft strokes, and the two sets of lifting shaft strokes are integerized to obtain an angle diagram.

[0086] The intersection angle needs to be preset in the angle diagram, and the intersection angle should not exceed 30 degrees;

[0087] In one specific embodiment, please refer to the appendix. Figure 1 As shown in the example on the right:

[0088] In the angle diagram, the forward feed axis stroke is defined to include the forward feed stroke and the backward feed stroke;

[0089] Set the intersection angle between the lifting shaft stroke and the forward feed stroke (set to 20 degrees in this case);

[0090] Set the intersection angle between the opening / closing shaft stroke and the back feed stroke (set to 30 degrees in this case);

[0091] (The number of intersection angles can be set by yourself) to facilitate the calculation of selection rules in subsequent data calculations;

[0092] Among them, the appendix Figure 1 The angle diagram shown is a representation of a drawn angle diagram, which is then redrawn as an angle diagram with the number of intersection angles set by the user.

[0093] Furthermore, in the next step S104, based on the attached... Figure 1 Angle diagram: A block diagram corresponding to the angle diagram is drawn using AutoCAD software;

[0094] The process of drawing the block diagram is as follows: Step S1041, based on the value of the slide stroke on the punch press as the height and the 360-degree angle as the width, first construct a block, and then divide the block into two equal parts at the top and bottom, and four equal parts on the left and right, as shown in the attached diagram. Figure 2 The drawing process is shown below;

[0095] Step S1042: Set the middle node and edge node after the box is divided into regions, and use the AUTO-CAD cloud line command and SPLINE function to draw the curves of the middle node and edge node.

[0096] As attached Figure 2 The schematic diagram of the curve drawing process shows five nodes in the given embodiment, as shown in the attached figure. Figure 4 As shown, these are the first node 1, the second node 2, the third node 3, the fourth node 4, and the fifth node 5, respectively. Note that the curve must be drawn from the center 1 to the end of 5; otherwise, the drawn line will be different.

[0097] Step S1043: Use the TRIM function in AutoCAD's trim command to index the curve and leave only the line.

[0098] The MIRROR command is used to mirror a curve as a line segment; see attached. Figure 2 The process is shown in the diagram.

[0099] In the next step S105, the slide stroke curve segments from the punch press are placed to the corresponding positions, and the following curves are drawn: forward feed curve, opening and closing curve, and lifting curve.

[0100] By overlaying the obtained feed curve, opening / closing curve, and lifting curve according to the block diagram, we obtain the operating curve diagram; as attached. Figure 3 As shown;

[0101] The method of overlap is as follows: place the four curves drawn above into their respective positions to obtain the running curve graph;

[0102] After the curve graph is drawn, please check whether the starting and ending points of each line segment correspond to the angles.

[0103] Step S106: Plot the interference curve based on the running curve graph, as shown in the attached figure. Figure 4-10 As shown;

[0104] Step S107, as attached Figure 11 As shown, the parameters for creating the interference curve are established in the software tool Excel, automatically rounded, and calculated to obtain the parameters for creating the interference curve; please refer to the appendix. Figure 12 As shown, the 3D interference curve is generated in the CATIA-V5 software interface. The whole process takes 3-5 minutes, which is much shorter than the previous 1-2 days.

[0105] It also includes the process of obtaining the first interference curve:

[0106] In one specific embodiment, as shown in the appendix Figure 4 As shown:

[0107] Step S1061: The corresponding positions of the slide stroke and forward stroke on the punch press during operation are obtained by measuring the running curve.

[0108] The relative positions of the slide block and the forward stroke on the punch press can be measured by running the curve graph.

[0109] Take one data point every 2.5 or 3 measurements, and keep the angle consistent for all subsequent measurements.

[0110] Otherwise, when finally plotting the 3D interference curve, the position of the points will be difficult to capture and connect (see appendix). Figure 4 The data in the middle is measured at one point every 3 measurements;

[0111] Based on the measured data, the intersection points of the punch press slide and the forward stroke can be plotted. Connecting each point with a cloud-shaped line will yield the curve of the punch press slide and the forward stroke line segment.

[0112] After removing the extra auxiliary lines, you can obtain the line graph of the punch press slide and the forward stroke line segment curve.

[0113] In one specific embodiment, as shown in the appendix Figure 5 As shown:

[0114] Step S1062: The corresponding positions of the slide stroke and opening / closing stroke on the punch press during operation are obtained by measuring the running curve.

[0115] Measure one point every 2.5 units. The more measurement points, the more accurate the final interference curve will be. Find the intersection point of the punch press slide and the opening and closing stroke, and connect the points with a cloud-shaped line to obtain the line segment curve of the punch press slide stroke and the opening and closing stroke.

[0116] After removing the extra auxiliary lines, you can obtain the line graphics of the punch press slide and the opening and closing stroke line segment curves.

[0117] Step S1063, as attached Figure 6 As shown, by merging the curves, the first interference curve diagram can be obtained by merging the line graphs of the punch slide and the forward stroke line segment curve and the line graphs of the punch slide and the opening and closing stroke line segment curve.

[0118] It also includes the process of obtaining the first interference curve:

[0119] Step S1064, as attached Figure 7 As shown in the diagram, the corresponding positions during the forward and lifting strokes can be measured from the operating curve.

[0120] By measuring one point for every two measurements, the intersection point of the forward stroke and the lifting stroke can be obtained. Connecting these points with a cloud-shaped line will yield the curve of the forward stroke and the lifting stroke.

[0121] After removing the extra auxiliary lines, you can obtain the line graph of the forward stroke and lifting stroke line segments;

[0122] Step S1065, as attached Figure 8 As shown in the figure, the corresponding positions of the forward stroke and the opening / closing stroke during operation can be measured from the running curve diagram;

[0123] By measuring one point for every two measurements, the intersection point of the forward feed stroke and the opening and closing stroke can be obtained. Connecting each point with a cloud-shaped line will yield the curve of the forward feed stroke and the opening and closing stroke.

[0124] After removing the extra auxiliary lines, you can obtain the line graph of the forward stroke and the opening and closing stroke line segments.

[0125] Step S1066, as attached Figure 9 As shown, after aligning the line graphs of the forward stroke and lifting stroke curves and the line graphs of the forward stroke and opening / closing stroke curves, the second interference curve graph can be obtained.

[0126] In addition, using the EXCEL software, a measurement point is created for every 1 degree, which is twice as accurate as creating a measurement point for every 2 degrees when manually plotting.

[0127] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
