Description
Technical Field
[0001] This invention relates to the field of mold design technology, and in particular to an intelligent design method for a side-edge trimming die core body and a bridging rib. Background Technology
[0002] Automotive stamping intelligent equipment molds are developed on a piece-by-piece basis, with each product possessing unique characteristics, complex structures, and high design difficulty. Due to differences in products, process solutions, customer technical standards, and production equipment, even when following unified design specifications, the structure of the same type of product (such as side panels, tailgates, and hoods) can vary significantly due to various complex scenarios. This places very high demands on the design engineers' capabilities and results in a long design and development cycle. For example, designing a side panel trimming mold using common CAD software and manual 3D modeling takes 25-30 days, as illustrated by the automotive body panel mold design method disclosed in patent CN119475564A. Currently, new energy vehicles are iterating rapidly with increasingly shorter development cycles, thus placing even higher demands on mold development cycles. Design occupies 25% of the mold development cycle time, and labor costs are rising, making it particularly urgent to improve mold design efficiency.
[0003] Existing mold design relies on CAD software commands and manual construction, resulting in low design efficiency, complex scenarios, low standardization, and designers needing to master numerous design standards. This places high demands on design engineers, leads to long personnel training cycles, and high costs. Furthermore, it fails to better meet customer timeline requirements, impacting the company's core competitiveness. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an intelligent design method for the side-edge trimming molded core body and the bridging reinforcement, aiming to improve design efficiency and save development costs.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0006] This application provides an intelligent design method for the side-edge trimming molded core body and the bridging rib, including:
[0007] S1. Classification and abstraction of main characteristics of the pressure core structure system;
[0008] S2, Standardized definition of input conditions for full-dimensional design;
[0009] S3, Modular design process and construction rule system establishment;
[0010] S4. Process visualization and standard logic closed-loop solidification form a complete material pressing core design system.
[0011] in,
[0012] In step S1, the structural form types are summarized, including hollowed-out form, guide type structure, and bridge reinforcement pattern; the changes in bridge reinforcement scenarios are summarized, and the bridge reinforcement types, including inner bridge reinforcement and outer bridge reinforcement rings, are determined; and the cross-sectional form of the bridge reinforcement is abstracted.
[0013] In step S2, the input conditions for the pressure core structure are summarized and defined as follows: 3D process model, trimming line, pre-forming contour line, post-forming contour line, feeding height, closing height, side processing direction line, and mold reference coordinate system; equipment input conditions, machine tool worktable and machine tool scrap hole; and planning scheme input conditions, including design standard selection, structural form selection, auxiliary mold style, limit form, pressure core guide form, and bridging rib form.
[0014] In step S3, a design flow is created, including the construction of the main body of the pressure core, the surface of the pressure core, the main reinforcement of the pressure core, the auxiliary reinforcement of the pressure core, the bridging reinforcement of the pressure core, the limiting arrangement, the lifting arrangement, and the guiding arrangement.
[0015] In step S4, the following steps are taken: defining the logical relationship between the bridging ribs of the pressing core and its surroundings; defining the main body generation rules for the pressing core profile; defining the construction rules for the main ribs of the pressing core; defining the construction rules for the auxiliary ribs of the pressing core; defining the bridging generation rules for the pressing core; defining the input conditions required for each functional structure; establishing a flowchart for generating bridging ribs inside the pressing core; establishing a flowchart for generating bridging ribs outside the pressing core; and defining the standard specifications and related logical relationships that each functional structure must meet.
[0016] In step S1, the overall structural form of the pressure core is summarized, and the system is divided into three main structural types: hollowed-out type, guide type structure, and bridging reinforcement style. The morphological characteristics and applicable scenarios of each type of structure are clarified. Focusing on the main functional component, the bridging reinforcement, the type is defined according to the actual application scenario. The two core styles, inner bridging reinforcement and outer bridging reinforcement ring, are distinguished, and the scenario adaptation differences between the two types of bridging reinforcement are sorted out. The core structure of the bridging reinforcement is abstracted, the standard T-section form is uniformly established, the basic structural form of the core component is solidified, and the standardized pre-design of the structural design is realized.
[0017] In the intelligent design method, customer templates are selected and called according to customer needs and planning requirements; the main body of the pressing core surface is generated according to process data and design planning; the main ribs of the pressing core outline are constructed according to the trimming line, the outline of the pre-forming process surface, and the pre-forming process surface; the auxiliary ribs and main ribs of the pressing core are constructed according to the trimming line, the outline of the pre-forming process surface, and the pre-forming process surface.
[0018] The intelligent design method includes an intelligent design and construction method for bridge reinforcement bars, which includes:
[0019] Setting parameters related to bridge reinforcement; dividing and classifying bridge reinforcement areas; setting bridge reinforcement generation rules; creating a flowchart for generating internal bridge reinforcement scenes.
[0020] In the intelligent design method, parameters are saved during model construction, so that the digital model and parting lines can be directly replaced during later design changes, thereby automatically updating the entity.
[0021] Compared with the prior art, the present invention has the following advantages:
[0022] The intelligent design method for the side panel molding core and the bridging rib is reasonable. It can complete the intelligent design of the side panel molding core and the bridging rib of the cover part, realize standardized and rapid design, improve design efficiency, save development costs, and shorten the mold development cycle.

[0039] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.
[0040] Although the invention has been shown and described herein with reference to specific embodiments, it is not intended to be limited to the details shown.

Many of these terms are used to describe features conforming to a cylindrical or generally cylindrical geometry with the feature as its radius and a central axis perpendicular to that radius. Unless otherwise specified, the terms are given the following meanings: The terms “longitudinal,” “longitudinal,” “axial,” and “axial” refer to a direction, dimension, or orientation parallel to the central axis. The terms “radial” and “radially” refer to a direction, dimension, or orientation perpendicular to the central axis. The terms “inward” and “inner” refer to a direction, dimension, or orientation extending radially toward the central axis. The terms “outward” and “outer” refer to a direction, dimension, or orientation extending radially away from the central axis.
[0042] In this specification, relative terms such as “horizontal,” “vertical,” “upward,” “downward,” “top,” and “bottom,” and their derivatives (e.g., “horizontal,” “downward,” “upward,” etc.) should be interpreted as referring to the direction described or the direction shown in the accompanying drawings. These relative terms are for ease of description and are not generally intended to require a specific direction.
[0043] like Figures 1 to 13As shown, this application provides an intelligent design method for the side-edge molding core body and the bridging rib, including:
[0044] S1. Classification and abstraction of main characteristics of the pressure core structure system;
[0045] S2, Standardized definition of input conditions for full-dimensional design;
[0046] S3, Modular design process and construction rule system establishment;
[0047] S4. Process visualization and standard logic closed-loop solidification form a complete material pressing core design system.
[0048] Further:
[0049] In step S1, the structural form types are summarized, including hollowed-out form, guide type structure, and bridge reinforcement pattern; the changes in bridge reinforcement scenarios are summarized, and the bridge reinforcement types, including inner bridge reinforcement and outer bridge reinforcement rings, are determined; the cross-sectional form of the bridge reinforcement is abstracted.
[0050] Specifically, the process involves summarizing the overall structural forms of the pressure core, systematically classifying it into three main structural types: hollowed-out, guide-type, and bridging reinforcement styles, and clarifying the morphological characteristics and applicable scenarios of each type of structure; focusing on the bridging reinforcement, a key functional component, the process involves defining its type based on actual application scenarios, distinguishing between two core styles: internal bridging reinforcement and external bridging reinforcement rings, and clarifying the differences in scenario adaptation between the two types of bridging reinforcement; abstracting the characteristics of the core structure of the bridging reinforcement, establishing a unified standard T-section form, solidifying the basic structural form of the core component, and achieving standardized pre-design of the structural design.
[0051] In step S2, the input conditions for the pressure core structure are summarized and defined as follows: 3D process model, trimming line, pre-forming contour line, post-forming contour line, feeding height, closing height, side processing direction line, and mold reference coordinate system; equipment input conditions, machine tool worktable and machine tool scrap hole; and planning scheme input conditions, including design standard selection, structural form selection, auxiliary mold style, limit form, pressure core guide form, and bridging rib form.
[0052] Specifically,
[0053] This step is the preparatory stage for the design parameters of the pressure core. It comprehensively reviews and defines all input elements required for the entire pressure core design process, clarifies all pre-design conditions, and eliminates issues such as missing parameters and inconsistent standards. It also refines the specific input requirements for each functional structure. Three main categories of basic input conditions are summarized: product process input (3D process model, trimming lines, front and rear contour lines, feeding height, closing height, side processing direction lines, mold reference coordinate system, and other core process parameters); equipment condition input (machine tool worktable parameters, machine tool scrap hole dimensions, and other equipment adaptation parameters); and scheme planning input (design standard selection, overall structural form, sub-type style, limit form, pressure core guide form, bridging rib form, and other scheme finalization parameters). Simultaneously, it precisely defines the specific input conditions for each functional structure of the pressure core, including the main body, surface, primary and secondary ribs, bridging ribs, limit, lifting, and guiding, ensuring that all design parameters are reliable and traceable.
[0054] In step S3, a design flow is created, including the construction of the main body of the pressure core, the surface of the pressure core, the main reinforcement of the pressure core, the auxiliary reinforcement of the pressure core, the bridging reinforcement of the pressure core, the limit arrangement, the lifting arrangement, and the guide arrangement.
[0055] Specifically,
[0056] Establish a complete standardized design flow for the pressure core, advancing the design according to a fixed process: main body construction → surface construction → main reinforcement construction → auxiliary reinforcement construction → bridging reinforcement construction → limiting arrangement → lifting arrangement → guiding arrangement, clearly defining the design sequence logic of each module. Develop a complete set of core construction rules, including rules for generating the pressure core surface, main reinforcement construction, auxiliary reinforcement construction, and bridging reinforcement, while defining the logical relationships between the bridging reinforcement and surrounding structures regarding assembly, fit, and interference avoidance.
[0057] In step S4, the logical relationship between the pressure core bridging ribs and the surrounding area is defined; the main body generation rules for the pressure core profile are defined; the main rib construction rules for the pressure core are defined; the auxiliary rib construction rules for the pressure core are defined; the bridging generation rules for the pressure core are defined; the input conditions required for each functional structure are defined; a flowchart for generating bridging ribs inside the pressure core is established; a flowchart for generating bridging ribs outside the pressure core is established; and the standard specifications and related logical relationships that each functional structure must satisfy are defined.
[0058] In this intelligent design method, customer templates are selected and called according to customer needs and planning requirements; the main body of the pressing core is generated according to process data and design planning; the main ribs of the pressing core outline are constructed according to the trimming line, the outline of the pre-forming process surface, and the pre-forming process surface; and the auxiliary ribs and main ribs of the pressing core are constructed according to the trimming line, the outline of the pre-forming process surface, and the pre-forming process surface.
[0059] Intelligent design methods include intelligent design and construction methods for bridge reinforcement bars, which include:
[0060] Setting parameters related to bridge reinforcement; dividing and classifying bridge reinforcement areas; setting bridge reinforcement generation rules; creating a flowchart for generating internal bridge reinforcement scenes.
[0061] In the intelligent design method, parameters are saved during model construction, so that the digital model and parting lines can be directly replaced during later design changes, thereby automatically updating the entity.
[0062] The intelligent design method of the side panel trimming molding core and the bridging rib of this application is reasonable and can complete the intelligent design of the side panel molding core and the bridging rib of the cover part, realize standardized and rapid design, improve design efficiency, save development costs, and shorten the mold development cycle.
[0063] The specific embodiments of the present invention are as follows:
[0064] like Figures 1 to 13 As shown, this invention provides an intelligent design method for the main body and cross-bracing ribs of a side-wall trimming mold pressing core. It abstracts two types: side-wall and non-side-wall. A standardized design process is established for the side-wall type pressing core. Logical constraints are applied to the position and spacing of the nitrogen spring, its relationship with the machine tool, process input, and the main pressing core structure. During the intelligent generation of the side-wall trimming mold and pressing core, calculations are performed based on the logical relationships of each part. Standard parts such as the main body structure of the side-wall mold, the pressing core structure, the cross-bracing ribs, and standard components can be quickly generated to meet the needs of various scenarios.
[0065] The side trimming die mainly consists of three parts: 1. upper die, 2. pressure core, and 3. lower die (the lower die can be divided into a punch and a punch seat, as determined by customer specifications and actual development). The trimming die is based on the following relationship between its main components: the lower die is mounted on the lower table of the press, the upper die is mounted on the slide of the machine tool, and the pressure core is mounted in the die cavity. The slide of the machine tool drives the upper die and the pressure core to move downward. The pressure core first contacts the lower die and receives the force from the lower die surface. The pressure core's nitrogen spring is compressed through the pressure core, and it continues to move. The upper die cutting block and the lower die cutting edge work together to complete the trimming function, realize the waste material shearing, and end one work cycle.
[0066] like Figure 1 As shown, the stamping production consists of trimming dies and equipment, mainly composed of 8 modules: upper die body 1, trimming die 2, nitrogen spring 3, pressure core 4, trimming punch 5, lower die body 6, machine tool lower table 7, and machine tool slide 8.
[0067] like Figure 2 and Figure 3As shown, the pressure core module is divided into 13 functional parts. These 13 functions and the functional nitrogen spring are designed intelligently using intelligent methods. It includes the outer guide of the pressure core 11, the inner guide of the pressure core 12, the pressure core limit 13, the bottom limit of the pressure core 14, the nitrogen spring of the pressure core 15, the inner working blade block 16, the pressure core bridging rib 17, the outer working blade block 18, the pressure core auxiliary rib 19, the pressure core conical balance block 20, the pressure core lifting 21, the pressure core profile 22, and the pressure core outline main rib 23.
[0068] Due to variations in product shape and structure, the design of the pressure core and its reinforcing ribs can be complex, leading to numerous structural variations and consequently, complex practical applications. Pressure core types include: Figure 4 Scene 1 and Figure 5 Scenario 2, and Figure 6 Scene 3.
[0069] To meet the needs of various scenarios, the various functional structures and bridging ribs of the pressure core can be intelligently generated and arranged. The main body of the pressure core is decomposed and abstracted into: surface part, matching cutting edge, contour main rib, auxiliary rib, and bridging rib. Rules are set for the generation of the structure of each part and the arrangement of standard parts.
[0070] Because the structure of the pressure core is influenced by product shape, process plan, production equipment, and mold standards (mold design), input conditions are a crucial prerequisite, whether developing intelligent generation algorithms and programs for the pressure core body and bridging ribs, or designing the intelligent structure of the pressure core body and bridging ribs. For example... Figure 7 The input conditions are shown; and as shown Figure 8 The flowchart shown is a design flowchart for the intelligent generation of the pressure core body and the intelligent arrangement of the bridging ribs.
[0071] Methods, steps, and rules for intelligent generation of the core material and intelligent arrangement of the bridging ribs:
[0072] 1. Select and call customer templates based on customer needs and planning requirements, including: structural style, sub-type, limit style, guide type, bridging rib type, and pressure source coefficient;
[0073] 2. Generate the main body of the pressing core surface based on process data and design planning. Construction method and rules: The program uses the outline of the pressing core surface to stretch the solid along the Z direction. The upper end is roughly offset by the pressing core surface. The offset distance is based on the configuration parameters (customer requirements or design standards). The lower end is cut using the pre-forming process surface.
[0074] 3. Construct the main ribs of the pressing core outline based on the trimming lines, the pre-forming process surface contour lines, and the pre-forming process surface; construction scheme and rules:
[0075] (1) Outer contour line of the main rib of the pressing core: Construct intermediate parts according to the rules of the outer contour line of the main rib of the pressing core;
[0076] (2) Cutting surface of the pressing core: The process surface before molding is offset along the +Z direction by "1 / 2 of the wall thickness of the pressing core surface";
[0077] (3). Bottom surface of the pressing core: "H = cutting edge height + 30 + guide plate length + 10" or "Z coordinate value of the bottom surface of the pressing core = Z coordinate value of the upper press table - 140 (60 + 40 + 40)" at the lowest position of the profile surface from the bottom surface of the pressing core, and the Z coordinate value of the bottom surface of the pressing core is rounded up;
[0078] (4) Take the outer contour of the pressure core containing the box, calculate the length L of the box, and determine the minimum height H of the pressure core by referring to the table to ensure that the lowest point of the process surface is H away from the bottom surface of the pressure core. The Z coordinate value of the bottom surface of the pressure core is rounded.
[0079] (5) The height of the main body of the pressure core must meet both rules 1 and 2 simultaneously;
[0080] (6) If the distance between the boundary of the main reinforcement and the trimming edge exceeds 50mm, diagonal reinforcement needs to be generated. The minimum spacing of the diagonal reinforcement is 100mm.
[0081] (7) Use the outer contour line of the main rib of the pressure core to offset the non-cutting edge side to obtain the inner contour line of the main rib of the pressure core. Use the inner and outer contour lines of the main rib of the pressure core to stretch along the -Z direction. Use the bottom surface of the punch to trim the upper end of the stretched entity and use the cutting surface of the pressure core rib to trim the lower end.
[0082] (8) Standard parameters for the height of the main reinforcing bar of the core:
[0083]
[0084] 4. Construct the main and auxiliary reinforcing bars of the pressing core based on the trimming lines, the outline of the pre-forming process surface, and the pre-forming process surface; construction scheme and rules:
[0085] (1) Construct the cutting surface of the core reinforcement: Use the pre-forming process profile to offset "core profile wall thickness 1 / 2" along the +Z direction;
[0086] (2) Center line of the main rib of the pressing core: offset the outer contour line of the main rib of the pressing core to the non-cutting edge side by "1 / 2 of the thickness of the main rib of the pressing core";
[0087] (3) System planning table: "Auxiliary reinforcement location generation type";
[0088] (4) Rule table configuration: center spacing of auxiliary reinforcement: 300~400mm, default value: 330mm;
[0089] (5) If the system plan is "Auxiliary rib position generation surface matches type = Yes", then the upper end cutting surface of the auxiliary rib is trimmed using the pre-forming process surface; if the system plan is "Auxiliary rib position generation surface matches type = No", then the upper end cutting surface of the auxiliary rib is trimmed using the punch rib cutting surface. The perimeter of the auxiliary rib is trimmed using the punch main rib centerline.
[0090] (6) All auxiliary rib positions need to be rounded relative to the mold coordinate system.
[0091] (7) The auxiliary ribs of the pressure core are made on the upper surface of the mold and the bottom surface of the pressure core in the +Z direction, and the other construction methods are the same.
[0092] The intelligent design and construction methods and rules for its bridge reinforcement are as follows:
[0093] (1) Setting relevant parameters for the bridge reinforcement;
[0094] (2) Division and classification of bridging reinforcement areas, such as Figure 9 As shown, it is divided into outer bridging bars and inner bridging bars;
[0095] (3) Rules for generating bridge reinforcement bars:
[0096] The outer ring of the side enclosure is closed and shaped by the enclosing box. The number of bridging ribs in the X-axis = enclosing box size A / center spacing of bridging ribs (configuration), rounded up.
[0097] Number of vertical bridging bars in Zone 3 = Enclosure box size B / Bridging bar center spacing (configuration), rounded up;
[0098] Number of vertical bridging bars in Zone 4 = Enclosure box size C / Bridging bar center spacing (configuration), rounded up;
[0099] After calculating the quantity of the bridging reinforcement in zones 3 and 4, they are evenly distributed in the layout direction, with the position rounded relative to the mold coordinate system.
[0100] U-shaped bridging reinforcement bars or the shortest distance connecting the main reinforcement bars of the outer contour are installed at the upper and lower ends of the B-pillar in the middle of the side wall and at the gap position. The center distance between the two reinforcement bars is equal to the size of the enclosure box D + 50mm (configuration).
[0101] (4) Scene 1 of the inner bridge reinforcement and its generation flowchart, as follows: Figure 10 and Figure 11 As shown;
[0102] (5) Scene 2 of the inner bridge reinforcement and its generation flowchart, as follows: Figure 12 and Figure 13 As shown;
[0103] This research utilizes a C++-based backend kernel algorithm and integrates UG OPENAPI, UISTYLER, and CAA interfaces on the frontend to automatically generate intelligent 3D solid models of the blank holder core and bridging reinforcement in UG and CATIA 3D design software. 1. Input data analysis, process model virtualization, analysis of each sheet boundary, intelligent topology, and repair of broken surfaces are performed to meet the needs of subsequent solid model cutting; parting line spline processing eliminates gaps and step differences, ensuring smooth curves. 2. Abstract cross-sectional models are analyzed and categorized into N styles. 3. Design specifications and requirements are reviewed, and structural rules, dimensional rules, strength rules, minimum design principles, and appropriate spatial adjustment principles are summarized into logical expressions, constructing spatial coordinates based on part features and parameters. 4. First, select the abstract template type based on the structural form and hollowing method, call the interface function, and use the process CAD model to generate the blank solid of the pressure core. Calculate the pressure core height based on the feeding height, closing height, and strength rules. Generate the outer frame ribs based on the parting line, escape dimensions, and blank boundary. Automatically generate guide structures, lifting structures, limiting structures, balancing structures, etc., according to design rules, and automatically color them. 5. Save parameters during model construction so that the CAD model and parting line can be directly replaced during later design changes, thereby automatically updating the solid.
[0104] The above is an illustrative description of the invention in conjunction with the accompanying drawings. Its method, rules, and concepts are relatively novel, comprehensively considering process solutions, customer requirements, and equipment inputs. The mold structure constructed using this method can adapt to changes in various scenarios. Combined with computer algorithms and program development, it achieves the goal of intelligent and rapid generation of mold structures. With increasingly shorter development cycles and rising labor costs, this invention effectively solves efficiency problems, reduces design costs, achieves standardized design, and greatly improves mold quality, bringing significant economic benefits to mold manufacturers and OEMs.
