Description

Technical Field

[0001] This application relates to the field of automotive mold design, specifically to an automatic arrangement design method, device, equipment, and storage medium for lifting punches. Background Technology

[0002] With the rapid development and intensified competition in the automotive manufacturing industry, automotive body panel molds, as key process equipment for body forming, directly impact the development efficiency of the entire vehicle through their design and manufacturing cycle and quality. Currently, in the production, assembly, and maintenance of molds, the lifting operation of punches is an indispensable step. The industry has an urgent overall demand for the safety and stability of lifting device layout schemes, as well as the standardization and efficiency of the design process.

[0003] In related technologies, the arrangement of lifting devices for automotive body panel mold punches typically relies on the experience of designers and is carried out manually. Designers open the punch model in 3D design software, manually identify the top surface geometry, manually select the lifting position within the preset process area, and use the lifting model from the standard parts library for assembly. Finally, the rationality of the arrangement scheme is verified by visual observation or simple interference checks.

[0004] However, this existing technology has the following technical problems: manual identification of features and placement of points is time-consuming and cannot meet the fast-paced development needs of modern automobile manufacturing; relying on experience-based judgment lacks accurate geometric fit and stress analysis algorithms, which can easily lead to loose fit or uneven stress between the lifting device and the top surface of the punch, resulting in mold damage and lifting safety hazards; different designers provide different placement schemes, making it difficult to achieve design standardization, and when the mold design changes and needs to be iterated, manual solutions cannot be updated quickly, increasing maintenance costs.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0020] In a first aspect, embodiments of this application provide an automatic arrangement design method for lifting punches.

[0021] Reference Figure 1 , Figure 1 This is a flowchart illustrating the automatic arrangement design method for punch lifting in this application, as shown below. Figure 1 As shown, the automatic arrangement design method for punch lifting includes: Step S1: Select the corresponding lifting standard part from the preset model library according to the attribute parameters of the punch; In this embodiment, based on the actual lifting requirements of the punch, key attribute parameters characterizing the physical and geometric properties of the punch to be processed are first acquired. Then, a pre-built digital model library containing various specifications of lifting standard parts is accessed. Each lifting standard part in the library is associated with its own technical specifications, such as load-bearing capacity, structural dimensions, and installation interfaces. Finally, the acquired attribute parameters of the punch are compared and evaluated with the technical specifications of each lifting standard part in the library to select one or more lifting standard parts that are functionally and performance-compatible with the punch. By selecting the corresponding lifting standard parts from the pre-set lifting standard part model library, the standardization, efficiency, and reliability of lifting standard part selection can be ensured, improving design consistency and reducing compatibility risks.

[0022] Step S2: Discretize the lifting standard part model and punch to obtain discrete data; In this embodiment, the surfaces of the lifting standard part model and the punch are processed by meshing and discretization, transforming the continuous and complex three-dimensional geometric surface into a set of discrete data that can be efficiently processed by computer algorithms. This establishes a unified and computable digital foundation for the subsequent accurate analysis of the optimal fitting position, avoiding the qualitative judgment that relies on visual observation or simple interference checks, and improving the accuracy of the fitting analysis.

[0023] Step S3: Calculate the fit between the lifting standard component layout surface and the top surface of the punch based on the discrete data, so as to calculate the optimal fit position between the lifting standard component layout surface and the top surface of the punch.

[0024] In this embodiment, using the two sets of discrete data obtained through mesh discretization in step S2, representing the lifting standard component arrangement surface and the top surface of the punch respectively, the optimal fit between the lifting standard component arrangement surface and the top surface of the punch is calculated. In some embodiments, the fit is characterized by parameters that reflect the physical tightness of the fit, such as the effective contact area, average gap, or maximum gap between the two. By adjusting the spatial pose of the lifting standard component relative to the punch (especially the depth along the preset normal) and continuously evaluating the fit index under different poses, a state that maximizes the fit (e.g., maximizing the contact area and minimizing the gap) is found. The spatial position corresponding to this state is determined as the optimal fit position. In this way, this application ensures that the lifting standard component can achieve maximum tightness of fit with the irregular surface of the punch, thereby effectively distributing the load, avoiding local stress concentration, and significantly improving the safety of the lifting operation and the service life of the mold.

[0025] Furthermore, by automatically identifying the bottom and top surfaces of the punch, a Cartesian coordinate system is established based on the bottom surface, and the z-axis is defined as the normal perpendicular to the bottom surface.

[0026] In this embodiment, refer to Figure 2 , Figure 2 This is a schematic diagram of the Cartesian coordinate system constructed based on the bottom surface of the punch in this application. The punches for automotive molds become highly complex after multiple design processes, and the spatial structure of the punch top surface is irregular. When manually arranging the lifting components, it is difficult to accurately position them in the correct location within a short time. To ensure rapid and accurate lifting and avoid excessive time consumption, a reasonable lifting arrangement scheme must be designed, which requires automatic identification of the punch top and bottom surfaces. The punch top surface is divided into many sections with significant elevation changes and numerous complex structures. If designers were to manually arrange the lifting components based on the surface conditions of these structures and design each one individually, it would be extremely time-consuming. This embodiment automatically identifies the punch top and bottom surfaces, establishes a Cartesian coordinate system based on the punch bottom surface, defines the z-axis as the normal perpendicular to the bottom surface, and then identifies the spatial coordinate system at each structural point on the punch top surface, providing data support for subsequent fitting analysis of standard lifting parts. Figure 2 In the diagram, number 1 represents the punch, number 2 represents the top surface of the punch, and number 3 represents the bottom surface of the punch.

[0027] Furthermore, in one embodiment, the automatic identification of the bottom and top surfaces of the punch specifically includes the following steps: The bottom surface of the punch is automatically identified and a local Cartesian coordinate system is constructed using a preset algorithm (such as edge detection and plane fitting algorithm). In this embodiment, all surfaces VF1 of the punch 1 and all secondary cutting surfaces VF2 of the product (such as automotive body panels) are obtained. The secondary cutting surfaces are the surfaces on the product (such as automotive body panels) that need to be closely fitted with the top surface of the punch during the mold closing process for precise positioning or auxiliary forming (not the main punching edge). All surfaces in VF1 are traversed and their center points are obtained. Then, the distance between them and the surfaces in VF2 is calculated. When the distance is less than a fixed value L, the surface in VF1 is determined to be the top surface of the punch and is placed into a new set VF3. After the traversal is completed, all surfaces in VF3 are summed to obtain the complete top surface of the punch. The bottom surface of the punch is automatically identified according to the Z-axis value in the pre-set global coordinate system and a local Cartesian coordinate system is constructed. When the user selects the lifting arrangement point on the top surface of the punch, the three-dimensional coordinates of the point will be automatically generated. At this stage, the Z-axis value of the coordinates is a fixed offset based on the bottom surface of the punch. The positioning and calculation are mainly performed using the X and Y axis coordinate values. This algorithm automatically identifies the top and bottom surfaces of the punch and constructs a local Cartesian coordinate system. Combined with the product's secondary entry surface constraint, it accurately and efficiently determines the three-dimensional position of the lifting arrangement point, improving the automation level and geometric adaptation accuracy of the lifting point positioning.

[0028] Furthermore, in one embodiment, selecting the corresponding lifting standard part from a preset model library based on the attribute parameters of the punch specifically includes: S101: Based on the weight, material, and shape of the punch, match the lifting standard parts corresponding to the weight, material, and shape of the punch from the preset model library; S102: Preview the arrangement of the matched lifting standard parts and punches to determine whether the selected lifting standard part model is appropriate.

[0029] In this embodiment, key attribute parameters of the punch are first obtained, including weight, material (which determines its maximum load-bearing capacity), and shape (especially symmetry). Based on these parameters, lifting standard parts with matching mechanical properties (such as load-bearing capacity) and physical forms are intelligently selected from the lifting standard parts library. Automatic matching is performed using quantifiable parameters such as weight, material, and shape to ensure the accuracy and reliability of the lifting standard parts selection. After selecting the lifting standard parts, the 3D model of the lifting standard parts is retrieved and previewed on the punch, such as... Figure 3 and Figure 4As shown, the system allows users to visually verify the layout effect. If a user is not satisfied with the current layout, they can directly select a new layout or replace the lifting standard parts in the preview interface. The assembly model and preview screen will be updated in real time according to the new layout until a lifting layout that meets the design requirements is obtained. By quantifying key parameters such as the weight, material, and shape of the punch, intelligent matching and visual preview of the lifting standard parts and punches are achieved. This allows users to adjust the layout in real time, significantly improving the accuracy and reliability of lifting standard part selection and increasing design efficiency. Figure 3 In the text, number 4 indicates a standard lifting component.

[0030] Furthermore, in one embodiment, the discretization of the surfaces of the lifting standard component and the punch to obtain discrete data specifically includes: S201: Determine the shape and size of each surface of the lifting standard component, and perform mesh discretization on the surface of the lifting standard component to obtain discrete point data of the surface of the lifting standard component; S202: The surface of the punch is discretized by meshing to obtain the discrete point data of each surface of the punch.

[0031] In this embodiment, the model data of the lifting standard component selected by the user is read to determine the shape and area of ​​the arrangement surface of the lifting standard component. The arrangement surface is then meshed and discretized, transforming the continuous curved surface into calculable discrete points for subsequent matching with the top surface of the punch. Similarly, the automatically identified top surface of the punch is meshed and discretized, transforming the continuous curved surface into calculable discrete points. Based on the three-dimensional coordinates (x, y, z) of the mesh nodes, a digital elevation model of the top surface of the punch is constructed. The purpose of constructing this digital elevation model is to transform the complex continuous curved surface into calculable and analyzable discrete mesh data, providing a geometric basis for the precise fitting, automatic matching, and visual arrangement of the lifting standard component, thereby improving assembly accuracy and design automation.

[0032] Furthermore, the calculation of the fit between the arrangement surface of the lifting standard component model and the top surface of the punch based on the discrete data specifically includes: S301: Based on the coordinates of discrete points on the surface of the lifting standard part, obtain the envelope of the lifting standard part; based on the coordinates of discrete points on the top surface of the punch, obtain the envelope of the punch. S302: Based on the envelope of the punch and the envelope of the lifting standard part, obtain the intersection surface between the punch and the lifting standard part; S303: The optimal fit position between the lifting standard component layout surface and the top surface of the punch is calculated based on the perpendicular line from each discrete point on the intersecting surface to the Z-axis of the Cartesian coordinate system.

[0033] In this embodiment, the envelope of the lifting standard component is first obtained within the discretized x and y coordinate range (see...). Figure 5 (The part marked "T-body"), then, traversing the envelope of each face of the punch to obtain the face that intersects with the lifting standard part, and then based on each discrete grid point on the arrangement surface of the lifting standard part, draw a perpendicular line parallel to the z-axis to calculate the fit between the arrangement surface of the standard part and the top surface of the punch, and solve for the optimal fit position with the maximum contact area and the minimum gap between the two, to ensure the complete fit between the lifting standard part and the top surface of the punch, and avoid mold damage caused by local stress concentration.

[0034] Furthermore, the calculation of the optimal contact position between the lifting standard component arrangement surface and the top surface of the punch specifically includes: S3011: Obtain all distances between the lifting standard component layout surface and the top surface of the punch by drawing perpendicular lines from each discrete point on the lifting standard component layout surface; S3012: Treat these distances as a set, move the lifting standard component downward by each distance, and obtain the contact surface between the lifting standard component's arrangement surface and the top surface of the punch. S3013: When the contact area reaches its maximum value, the distance corresponding to this state is determined as the final installation depth, thereby achieving optimal fit between the lifting standard part and the top surface of the punch.

[0035] In this embodiment, the distance H from the lifting standard part arrangement surface to the top surface of the punch can be obtained by drawing a vertical line. All H values ​​are grouped into a set VH. The lifting standard part is moved downward by each H value. After the movement, the contact surface S between the lifting standard part arrangement surface and the top surface of the punch is obtained. When S reaches its maximum value, the H value in the current state is obtained as the final punch installation depth.
