Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts manufacturing technology, specifically to an interlocking wedge, a method for generating an interlocking wedge, an electronic device, and a computer-readable storage medium. Background Technology
[0002] In the cold stamping production of automotive body panels, for parts with complex curved surfaces or flanges, multiple wedges at different angles are typically used to drive trimming cutter blocks to complete trimming operations sequentially or collaboratively from different directions. When the trimming trajectories of two wedges are adjacent or intersect, a "cutter contact zone" is formed, and this area is crucial to the trimming quality and the stability of the die operation.
[0003] In related technologies, the design of the cutting area between two wedges generally relies on the designer's experience. To avoid interference, the pre-set wedge avoidance space gap is too large, which will cause the first cutting blade to need an excessive amount of engagement to complete the cut. This will not only increase the trimming resistance, but also easily cause the sheet metal to deform and the burrs to increase. At the same time, it will also have a great impact on the wear of the cutting edge. Summary of the Invention
[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an interlocking wedge, which, when used in cold stamping production, can effectively control burrs on the product and improve the service life of the wedge cutter block.
[0005] In a first aspect, embodiments of this application provide an interlocking wedge, comprising: a first wedge having a boss structure extending along the cutting edge direction of the first wedge; and a second wedge having a groove structure adapted to the shape of the boss structure, the groove structure being used to accommodate the boss structure; wherein a fitting gap is provided between the boss structure and the groove structure, the fitting gap being used to limit the radial offset between the first wedge and the second wedge.
[0006] In some embodiments, the first mounting surface of the first wedge facing the mounting plane is horizontally disposed with the mounting plane, and the second mounting surface of the second wedge facing the mounting plane forms a preset angle with the mounting plane, so that the direction of the mold closing movement of the second wedge relative to the first wedge is the inclined direction of the preset angle.
[0007] In some embodiments, the fitting gap is also used to form a guide when the first wedge and the second wedge perform the mold closing movement, and the fitting gap is 1 mm-2 mm.
[0008] In some embodiments, a first step and a second step are formed on the first wedge and the second wedge, respectively. The first step and the second step cooperate with each other after the first wedge and the second wedge are closed to limit the relative displacement of the first wedge and the second wedge along the direction of the mold closing movement.

[0011] Secondly, embodiments of this application provide a method for generating an interlocking wedge, comprising: analyzing the motion relationship and force conditions of a first wedge and a second wedge; determining the layout of the first wedge and the second wedge based on the motion relationship and force conditions; determining the preset tilt angle and installation position of the first wedge and the second wedge relative to the mounting plane according to the design requirements of the target process; determining the three-dimensional models of the first wedge and the second wedge based on the preset tilt angle and installation position, and analyzing the motion trajectory between the first wedge and the second wedge in a preset simulation environment; optimizing the structure of the three-dimensional model based on the motion trajectory, and generating an optimized three-dimensional model; and generating an interlocking wedge based on the optimized three-dimensional model.
[0012] In some embodiments, structural optimization of a three-dimensional model is performed based on a motion trajectory, and an optimized three-dimensional model is generated, including: forming a boss structure on a first wedge and a groove structure on a second wedge based on the motion trajectory; and generating an optimized three-dimensional model based on the first wedge, the boss structure, the second wedge, and the groove structure.

[0014] Fourthly, embodiments of this application provide a computer-readable storage medium storing a program or instructions that, when executed by a processor, implement the steps of the interlocking wedge generation method of the first aspect.
[0015] The technical solution provided in this application analyzes the motion trajectory of the interlocking wedge during operation to determine the optimal relative motion direction between the two wedges in the interlocking wedge, thereby guiding the limit avoidance gap between the cutting blocks and scientifically planning the motion sequence and path of the cutting blocks.

[0019] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While some embodiments of this application are shown in the drawings, it should be understood that this application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this application. It should be understood that the drawings and embodiments of this application are for illustrative purposes only and are not intended to limit the scope of protection of this application.
[0020] It should be understood that the steps described in the method embodiments of this application may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this application is not limited in this respect.
[0021] The interlocking wedge and its generation method, electronic device and storage medium provided in this application are described below with reference to the accompanying drawings.
[0022] refer to Figure 1 This is a schematic diagram of the interlocking wedge structure provided in the embodiments of this application.
[0023] Specifically, the interlocking wedge provided in this application is preferably installed in a cold stamping trimming die, including a first wedge 1 and a second wedge 2. The first wedge 1 is provided with a boss structure 11, which extends along the cutting edge direction of the first wedge 1. The second wedge 2 is provided with a groove structure 21 that matches the shape of the boss structure 11. The groove structure 21 is used to accommodate the boss structure 11. A fitting gap 3 is provided between the boss structure 11 and the groove structure 21. The fitting gap 3 is used to limit the radial offset between the first wedge 1 and the second wedge 2.
[0024] The boss structure 11 of the first wedge 1 is located at the end of the cutting block in the first wedge 1 and extends along the cutting edge direction of the cutting block in the first wedge 1. It can be used as the rear entry cutting edge in the cold stamping process to trim the parts. The groove structure 21 of the second wedge 2 is located at the end of the cutting block in the second wedge 2 and extends along the cutting edge direction of the cutting block in the second wedge 2. It matches the shape of the boss structure 11 of the first wedge 1 and can be used as the first entry cutting edge in the stamping process to trim the parts. A fitting gap 3 is provided between the boss structure 11 and the groove structure 21. The fitting gap 3 is used to limit the radial offset between the first wedge 1 and the second wedge 2, so that the cutting heads of the first wedge 1 and the second wedge 2 do not have rigid collisions during the entire movement. This improves trimming accuracy and reduces burr size while achieving effective avoidance.
[0025] As an optional embodiment, the first mounting surface of the first wedge 1 facing the mounting plane is horizontally arranged with the mounting plane, and the second mounting surface of the second wedge 2 facing the mounting plane forms a preset angle with the mounting plane, so that the direction of the mold closing movement of the second wedge 2 relative to the first wedge 1 is the inclined direction of the preset angle.
[0026] Specifically, the cold stamping trimming die also includes an upper die base with an mounting plane. The mounting plane serves as a reference plane for the installation and movement of the wedges. A first wedge 1 and a second wedge 2 are mounted on the mounting plane. The first mounting surface of the first wedge 1 facing the mounting plane is horizontally aligned with the mounting plane, and the second mounting surface of the second wedge 2 facing the mounting plane forms a preset angle with the mounting plane. When the mold closing movement is performed with the movement direction of the first wedge 1 as the reference, the second wedge 2 is tilted relative to the movement direction of the first wedge 1 at the preset angle. By determining the direction of the mold closing movement of the first wedge 1 and the second wedge 2, the spatial relative position change trend of the first wedge 1 and the second wedge 2 during the movement can be further determined, thereby realizing the determination of the direction of the minimum clearance between the first wedge 1 and the second wedge 2 and the mold.
[0027] In this embodiment, the preset included angle is preferably in the range of 0° to 75° to ensure the force transmission efficiency of the wedge drive mechanism and the stability of the slider guide.
[0028] It should be noted that the arrangement of the first wedge 1 and the second wedge 2 includes, but is not limited to, the arrangement described above. In some cold stamping operations, the first mounting surface of the first wedge 1 may be at a preset angle to the mounting plane, and the second mounting surface of the second wedge 2 may be horizontally set to the mounting plane.
[0029] As an optional embodiment, the fitting gap 3 is also used to form a guide when the first wedge 1 and the second wedge 2 are in the mold closing motion, and the fitting gap 3 is 1 mm-2 mm.
[0030] Specifically, the fitting gap 3 is set along the relative motion direction of the first wedge 1 and the second wedge 2 during the mold closing motion. Based on spatial vector analysis and three-dimensional motion simulation, the fitting gap 3 provided in this application is determined to be in the range of 1mm-2mm, so that the first wedge 1 and the second wedge 2 can avoid collision while having the minimum engagement amount during the mold closing motion.
[0031] As an optional embodiment, a first step 12 and a second step 22 are formed on the first wedge 1 and the second wedge 2, respectively. The first step 12 and the second step 22 cooperate with each other after the first wedge 1 and the second wedge 2 are closed to limit the relative displacement of the first wedge 1 and the second wedge 2 in the direction of the mold closing movement.
[0032] Specifically, the first step 12 is formed at the end of the trimming cutting edge of the blade in the first wedge 1, and the second step 22 is formed at the end of the trimming cutting edge of the blade in the second wedge 2. The structures of the first step 12 and the second step 22 form a mutually cooperating structure after mold closing. There is also a fitting gap 3 between the first step 12 and the second step 22. The first step 12 and the second step 22, together with the above-mentioned boss structure 11 and groove structure 21, constitute a guide structure, which can restrict and lock the relative displacement of the first wedge 1 and the second wedge 2 in the mold closing direction.
[0033] As an optional embodiment, the height of the first step 12 and the second step 22 is not less than 2mm.
[0034] Specifically, during the cold stamping trimming process, the cutting edges of the blades in the first wedge 1 and the second wedge 2 need to withstand huge shear impact loads instantly. Therefore, the height of the first step 12 and the second step 22 needs to be not less than 2mm to provide sufficient section modulus, effectively resist lateral bending and plastic deformation, avoid blade chipping or breakage, and at the same time maintain the accuracy of the blade straightness, effectively controlling the size of burrs.
[0035] As an optional embodiment, the first wedge 1 has a first stroke in a direction perpendicular to the mounting plane, and the second wedge 2 has a second stroke in a direction perpendicular to the mounting plane. The first wedge 1 and the second wedge 2 coincide at the bottom dead center. The bottom dead center is the position where the cutting edges of the first wedge 1 and the second wedge 2 simultaneously reach their maximum stroke.
[0036] Specifically, during the mold closing process, the first wedge 1 has a first stroke in a direction perpendicular to the mounting plane, and the second wedge 2 has a second stroke in a direction perpendicular to the mounting plane. The point where the first and second strokes coincide is when the mold is fully closed, at which point the cutting edge simultaneously reaches its maximum stroke position, that is, at this time both the first wedge 1 and the second wedge 2 have moved to the bottom dead center. (Refer to...) Figure 2 This is a schematic diagram of the three-dimensional motion trajectory of the first wedge 1 and the second wedge 2 provided in this application embodiment. In this application embodiment, the bottom dead center where the first stroke of the first wedge 1 and the second stroke of the second wedge 2 coincide is point X. The actual motion trajectory of the cutting block in the first wedge 1 is vector AX, and the actual motion trajectory of the cutting block in the second wedge 2 is vector BX. The direction of the vector connecting points A and B represents the spatial position change trend of the cutting block in the second wedge 2 relative to the cutting block in the first wedge 1 at that moment, that is, the instantaneous relative motion direction of the first wedge 1 and the second wedge 2. It can be solved by the actual motion trajectory vector of the cutting block in the first wedge 1 and the actual motion trajectory vector of the cutting block in the second wedge 2.
[0037] Based on the solved relative motion direction vector and the fitting clearance 3, the first wedge 1 and the second wedge 2 are set to perform operations according to this relative motion direction. This ensures that the avoidance surfaces (i.e., non-cutting edge surfaces) of the cutting blocks in the first wedge 1 and the second wedge 2 are parallel to this direction and designed to allow for open-circuit operation. This ensures that during the entire motion process, the cutting blocks in the first wedge 1 and the second wedge 2 can minimize space occupation while avoiding interference, thereby achieving extreme avoidance.
[0038] It should be noted that when achieving extreme avoidance, since the range of the fitting gap 3 is relatively small, the invalid stroke that the first-fitting blade block (the blade block in the second wedge 2) needs to retract in advance to avoid the second-fitting blade block (the blade block in the first wedge 1) is correspondingly shortened, which makes the effective trimming stroke of the first-fitting blade block correspondingly extended. Therefore, the cutting length completed by the second-fitting blade block, i.e. the fitting amount, is preferably less than 13mm in this embodiment of the application.
[0039] According to the interlocking wedge provided in the embodiments of this application, by analyzing the motion trajectory of the interlocking wedge during operation, the optimal relative motion direction between the two wedges in the interlocking wedge is determined, thereby guiding the limit avoidance gap between the cutting blocks, and scientifically planning the motion sequence and motion path of the cutting blocks, ensuring that the structure of the cutting blocks can work under optimal stress, improving the insertion amount standard of the first cutting block, thereby effectively controlling the burr size of the product, and at the same time improving the service life of the cutting blocks.
[0040] refer to Figure 3 The above is a flowchart of a method for generating an interlocking wedge according to an embodiment of this application.
[0041] Step S301: Analyze the motion relationship and force conditions between the first and second wedges; Step S302: Based on the motion relationship and force conditions, determine the layout between the first wedge and the second wedge; Step S303: Based on the design requirements of the target process, determine the preset tilt angle and installation position of the first wedge and the second wedge relative to the mounting plane; Step S304: Determine the three-dimensional models of the first wedge and the second wedge based on the preset tilt angle and installation position, and analyze the motion trajectory between the first wedge and the second wedge in the preset simulation environment; Step S305: Optimize the structure of the 3D model based on the motion trajectory and generate the optimized 3D model; Step S306: Generate an interlocking wedge based on the optimized 3D model.
[0042] Specifically, based on the trimming contour of the target product, the cutting area that needs to be completed by the cooperation of two wedges is identified. Further, the motion transmission relationship between the first and second wedges during the mold closing process is preliminarily analyzed. This involves decomposing the actual working strokes of the first and second wedges into the strokes of the slider and the vertical stroke of the upper mold, respectively, providing constraints and optimization targets for the structural design. Simultaneously, the material, thickness, and trimming length of the sheet metal to be stamped need to be identified. The trimming force required by the wedges is preliminarily estimated using empirical formulas or finite element analysis. Further analysis of the transmission path and distribution of this trimming force on different mechanisms of the first and second wedges (including the wedge surface, slider, guide rail, etc.) is conducted to identify potential stress concentration areas or high-load components.
[0043] Furthermore, based on the above-mentioned kinematic relationship and force conditions, the driving sequence of the first wedge and the second wedge is determined accordingly, such as setting the first wedge as the rear-entry drive and the second wedge as the first-entry drive tool block.
[0044] Furthermore, based on the design requirements of the target process, the installation angles of the first wedge and the second wedge are determined. For example, the first wedge is set to be parallel to the installation plane, and the second wedge is set to have a certain preset angle with the installation plane. At the same time, it is also necessary to confirm the coordinates of the installation base points of the first wedge and the second wedge on the installation plane to ensure that the cutting block movement trajectories of the first wedge and the second wedge can correctly intersect the trimming contour line of the target product in three-dimensional space.
[0045] Furthermore, using 3D modeling software, a 3D model containing the first wedge, the second wedge, and the mounting plane is established. The motion trajectory of the 3D model is simulated to calculate the motion trajectory of the first wedge and the second wedge in 3D space, and to analyze whether there is any interference risk between the first wedge and the second wedge near the tool-connecting area.
[0046] Furthermore, based on the motion trajectories of the first and second wedges in three-dimensional space, it is determined that when the mold is fully closed, both the first and second wedges reach the bottom dead center, and the bottom dead centers coincide. The starting points of the first and second wedges are then connected to characterize the spatial positional change trend of the second wedge relative to the first wedge during the motion. The instantaneous relative motion direction of the first and second wedges is further solved. Furthermore, based on the solved relative motion direction vector and a preset fit clearance, the non-working parts (i.e., avoidance surfaces) of the first and second wedges in the three-dimensional model are redesigned. This ensures that the avoidance surfaces of the first and second wedges are strictly parallel to the instantaneous relative motion direction and arranged in an "open" configuration. This achieves that throughout the entire mold closing cycle, the first and second wedges maintain a fit clearance along this direction in the contact area, thereby achieving ultimate avoidance of the first and second wedges while avoiding motion interference.
[0047] Finally, based on the simulated setup of the first and second wedges, the first and second wedges in actual production were arranged to obtain an interlocking wedge capable of achieving extreme avoidance.
[0048] As an optional embodiment, the structure of the three-dimensional model is optimized based on the motion trajectory, and an optimized three-dimensional model is generated, including: forming a boss structure on the first wedge and a groove structure on the second wedge based on the motion trajectory; and generating an optimized three-dimensional model based on the first wedge, the boss structure, the second wedge and the groove structure.
[0049] Specifically, when optimizing the structure of the 3D model, the boss structure is located on the cutting block of the first wedge and forms the first cutting edge, and the groove structure is located on the cutting block of the second wedge and forms the second cutting edge. The extension direction of the boss structure and the guiding direction of the groove structure need to be parallel or coincident with the relative motion vector to ensure that the constraint degree of freedom of the boss structure and the groove structure is completely matched with the actual relative motion degree of freedom of the first and second wedge cutting blocks during operation. This achieves limit avoidance and reduces the engagement amount of the wedge cutting blocks, avoiding internal stress or motion jamming that affects the wedge movement due to the mismatch between the guiding direction and the motion direction, thus affecting the service life of the wedge.
[0050] According to the interlocking wedge generation method provided in this application embodiment, the optimal relative motion direction between two wedges in the interlocking wedge is determined by analyzing the motion trajectory of the interlocking wedge during operation. This guides the limit avoidance gap between the cutting blocks and scientifically plans the motion sequence and path of the cutting blocks, ensuring that the structure of the cutting blocks can work under optimal stress. This improves the standard for the engagement amount of the first engaging cutting block, thereby effectively controlling the burr size of the product and increasing the service life of the cutting blocks.
