Description

Technical Field

[0001] This invention relates to the field of vehicle sheet metal stamping technology, specifically to a method for laying out and manufacturing a stamped component, and a vehicle thereof. Background Technology

[0002] To meet functional, strength, and rigidity requirements, automotive sheet metal parts currently come in various external contour formats. Many parts have irregular contours and protruding parts. After the parts are unfolded, the shape of the stamping blank is also irregular, resulting in a large scrap area in the stamping blank and low material utilization. Summary of the Invention

[0003] The purpose of this invention is to provide a method for laying material, a manufacturing method, and a vehicle for stamping components, which can reduce the material consumption of stamping components and improve material utilization.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] In a first aspect, the present invention provides a method for applying material to a stamped component, comprising:

[0006] Flatten the stamped component to determine the main elements of the stamped component;

[0007] Extend the outer contour of the main component outward by a predetermined length to obtain a dividing contour line. Using the coincidence line between the dividing contour line and the stamped component as the boundary, divide the main component into several auxiliary components connected to the main component.

[0008] Using the stamping waste area of ​​the main component as the stamping blank corresponding to the auxiliary component, the material distribution scheme of the stamped component is obtained.

[0009] Furthermore, the stamping scrap area of ​​the main component includes an external scrap area and an internal scrap area. Depending on the size of the auxiliary component, the external scrap area or the internal scrap area is used as the stamping blank corresponding to the auxiliary component.

[0010] Furthermore, the determination of the stamping blank of the main component includes: calculating and determining the initial size of the blank based on the unfolded plane of the main component, wherein the dividing contour line is completely within the blank area; the stamping blank of the main component has a material buffer of a preset width at the edge position of the unfolded plane of the main component.

[0011] Furthermore, the stamping blank is a regular quadrilateral that can completely cover the segmented outline.

[0012] Furthermore, the stamping blank is a rectangle that can completely cover the segmented outline;

[0013] The length of the stamping blank = the unfolded length of the main component + 2% of the first compensation amount;

[0014] The width of the stamping blank = the unfolded width of the main component + 2 second compensation amount;

[0015] The first compensation amount and the second compensation amount are reasonably set based on the size of the main component and the stamping process.

[0016] Furthermore, it also includes dividing the main body component into several auxiliary components connected to the main body component by using the coincidence line between the dividing contour line and the stamped component as the boundary, verifying the stress distribution of the main body component and auxiliary components after the division by finite element analysis, and optimizing the dividing contour line based on the stress distribution results.

[0017] Secondly, the present invention provides a method for manufacturing a stamped component, comprising:

[0018] A stamping blank is provided, which is divided into sections according to the above-described method for laying out stamped components. The stamping blank includes a stamping area for the main component and a stamping area for auxiliary components located in the stamping scrap area of ​​the main component.

[0019] The stamping blank is stamped to obtain the main component and several auxiliary components;

[0020] Several of the auxiliary components are fixedly connected to the main component to obtain a stamped component.

[0021] Furthermore, the auxiliary components are fixed to the main components by welding, screwing, gluing, or riveting.

[0022] Furthermore, the main component and the auxiliary component are provided with a first overlapping part at the corresponding connection position, and the auxiliary component is provided with a second overlapping part that corresponds to and cooperates with the first overlapping part.

[0023] Thirdly, the present invention provides a vehicle including a stamped component, the stamped component being manufactured using the above-described method for manufacturing stamped components.

[0024] The present invention has the following unexpected beneficial effects:

[0025] This invention extends the outer contour of the main component outward by a predetermined length to obtain a segmented contour line. Using the overlap line between the segmented contour line and the stamped component as the boundary, several auxiliary components connected to the main component are obtained. The stamping waste area of ​​the main component is then used as the stamping blank for the auxiliary components, resulting in a material distribution scheme for the stamped component. This design reduces the overall outer contour size of the stamped component, allowing for the use of smaller stamping blanks during manufacturing, thus reducing material consumption. Furthermore, while stamping waste is often treated as waste in traditional methods, this invention integrates the auxiliary components into the stamping waste area of ​​the main component during simultaneous production. Small parts do not require separate mold or tooling development, eliminating additional tooling costs and enabling the reuse of waste without increasing mold or tooling costs. This improves material utilization and reduces manufacturing costs. Attached Figure Description

[0035] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0036] In one embodiment, see Figure 1 As shown, the present invention provides a method for fabrication of stamped components, comprising:

[0037] Flatten the stamped component to determine its main elements.

[0038] Extend the outer contour of the main component outward by a predetermined length to obtain a dividing contour line. Using the coincidence line between the dividing contour line and the stamped component as the boundary, several auxiliary components connected to the main component are obtained.

[0039] Using the stamping waste area of ​​the main component as the stamping blank corresponding to the auxiliary component, the material distribution scheme of the stamped component is obtained.

[0040] This design reduces the overall outer dimensions of the stamped component, allowing for the use of smaller stamping blanks and thus lowering material consumption. Furthermore, while traditional methods often treat stamping waste as waste, this invention integrates the auxiliary components within the main component's stamping waste area for simultaneous production. This eliminates the need for separately developed molds and tooling for smaller parts, reducing tooling costs and enabling the reuse of waste materials without additional mold and tooling costs. This improves material utilization and ultimately lowers manufacturing costs.

[0041] It should be noted that the determination of the main components requires comprehensive analysis from multiple dimensions. For example, the main components can be determined comprehensively from the following four dimensions.

[0042] 1) Geometric feature analysis: Autoform software is used to reverse unfold the stamped components, retain key forming features (such as bosses, flanges, etc.), and establish a curvature radius distribution cloud map of the unfolded parts. Areas with curvature change rate < first preset value are preferentially classified as main components.

[0043] 2) Functional priority division, taking the structural area that bears the main load in the stamped component (such as the reinforcing plate of the B-pillar of a car) as the main component.

[0044] 3) Material flow simulation: Autoform is used to perform stamping simulation and analyze the material flow trend. The region with a thickness reduction rate less than the second preset value is marked as the main component.

[0045] 4) Structural continuity judgment: The minimum spanning tree algorithm is used to identify the largest connected region to ensure that the number of connection nodes between the main component and the auxiliary component is greater than or equal to the third preset value.

[0046] In a preferred embodiment of the present invention, the stamping waste area of ​​the main component includes an external waste area and an internal waste area. Depending on the size of the auxiliary component, the external waste area or the internal waste area is used as the stamping blank corresponding to the auxiliary component.

[0047] Specifically, the external scrap area refers to the scrap portion formed around the main component after its outer contour extends outward by a predetermined length. Its shape is usually relatively regular and its area is relatively large. For example, in stamping parts for automobile bodies, the scrap generated around the periphery of some large flat parts falls into this category. The internal scrap area refers to the scrap generated due to punching operations inside the main component or due to the need for hollowing out in the structural design. This type of scrap often has a more complex shape and a relatively smaller area. For example, the scrap generated from drilling holes in some mechanical parts with multiple mounting holes belongs to the internal scrap area.

[0048] For smaller auxiliary components, using internal scrap areas with complex shapes but small areas as blanks can avoid wasting large areas of external scrap; while for larger auxiliary components, the larger area of ​​external scrap areas is just right, making full use of materials and reducing the overall waste.

[0049] By precisely matching the scrap area with the dimensions of auxiliary components, the need for purchasing new blanks is reduced, thus lowering material costs. Simultaneously, the more efficient use of scrap reduces scrap disposal costs. Furthermore, the rational utilization of scrap areas as blanks simplifies the stamping process to some extent. Because the blank is planned in advance based on the characteristics of the scrap area, the material flow and forming during stamping are more in line with expectations, reducing process adjustments caused by unsuitable blanks.

[0050] In a preferred embodiment of the present invention, the determination of the stamping blank of the main component includes: calculating and determining the initial size of the blank based on the unfolded plane of the main component, wherein the dividing contour line is completely within the blank area; the stamping blank of the main component is provided with a material buffer of a preset width at the edge position of the unfolded plane of the main component.

[0051] Based on the unfolded plane of the main component, the initial dimensions of the blank are determined through precise geometric calculations. For example, if the unfolded main component is a rectangle with length *a* and width *b*, then the initial dimensions of the blank should satisfy the requirement that the segmentation contour lines are completely within the blank's range in both length and width directions. Assuming that the maximum distances of the segmentation contour lines beyond the outer contour of the main component in the length and width directions are *x* and *y* respectively, then the initial dimensions of the blank are: length A = a + 2x, width B = b + 2y. For the unfolded plane of an irregularly shaped main component, specialized CAD software is required. Through boundary recognition and distance measurement functions, the maximum distance between the segmentation contour lines and the outer contour of the main component in each direction is determined, and the initial dimensions of the blank are then calculated. The irregular initial blank is then converted into a regular blank, which completely covers the irregular initial blank, reducing the difficulty of dimensional control of the stamping blank.

[0052] Precise initial blank dimensions ensure sufficient material supply for auxiliary components within the segmented contour lines, while the material buffer zone further guarantees the stability of material supply to the main components during the stamping process, thereby significantly improving the quality of stamped parts and reducing scrap rates. Furthermore, a well-designed blank size avoids excessive material waste, reducing blank procurement costs. Simultaneously, the improved quality and reduced scrap rates significantly lower subsequent rework and scrap costs.

[0053] A material buffer zone of a preset width is set at the edge of the unfolded plane of the main component. The width of the material buffer zone needs to be determined according to the stamping process and material characteristics. Generally speaking, for stamping ordinary metal sheets, if the material is thin (such as cold-rolled steel sheet with a thickness of less than 1mm), the width of the material buffer zone can be set to 5-10mm; if the material is thick (such as hot-rolled steel sheet with a thickness of more than 3mm), the buffer zone width can be appropriately increased to 15-20mm. Taking the stamped part of an automobile engine hood as an example, the width of the material buffer zone at the edge of the unfolded plane of its main component may be set to 12mm.

[0054] Material buffers play a crucial role in the stamping process. During stamping, material flows and deforms, and the material in the buffer replenishes areas of the main component prone to material shortages, such as complex curved transition areas or deep drawing sections, effectively preventing defects like cracking and wrinkling in the stamped parts. Simultaneously, during mold debugging and trial molding, the material buffer provides a certain margin of error for adjusting process parameters, facilitating the optimization of the stamping process. When faced with fluctuations in material properties between different batches or mold wear, the quality of the stamped parts can be ensured by adjusting process parameters and utilizing the material buffer, enhancing the adaptability of the stamping process to various production conditions.

[0055] Furthermore, the stamping blank is a regular quadrilateral that can completely cover the segmented contour lines. In the material procurement stage, regular quadrilateral blanks are easy to standardize, have ample market supply, are easy to procure, and have relatively stable prices. For example, common rectangular blanks have length and width dimensions that are easy to measure and record, facilitating communication with suppliers and enabling quick acquisition of required specifications. During the stamping process, the positioning and installation of regular quadrilateral blanks in the mold are simpler. Due to their regular shape, the blank is subjected to more uniform force during press operation, effectively reducing the stamping scrap rate caused by blank positioning deviations. Moreover, regular quadrilateral blanks are more convenient in subsequent secondary processing operations such as cutting and splicing, improving production efficiency.

[0056] Furthermore, the stamping blank is a rectangle that can completely cover the segmented outline;

[0057] The length of the stamping blank = the unfolded length of the main component + 2% of the first compensation amount;

[0058] The width of the stamping blank = the unfolded width of the main component + 2 second compensation amount;

[0059] The first compensation amount and the second compensation amount are reasonably set based on the size of the main component and the stamping process.

[0060] The first and second compensation amounts in this invention are not arbitrarily determined, but rather need to be reasonably set based on the size of the main component and the stamping process. For example, if the size of the main component is large, the range and extent of material flow during the stamping process will also increase accordingly. In this case, it is necessary to increase the first and second compensation amounts to ensure that the blank has enough material to meet the forming requirements of each part within the segmented contour line. If the main component is a rectangular plate with a length of L and a width of W, after analysis and evaluation of the stamping process, it is determined that a compensation amount of 5mm needs to be reserved in the length direction (i.e., the first compensation amount is 5mm) and a compensation amount of 3mm needs to be reserved in the width direction (i.e., the second compensation amount is 3mm). Then, the length of the stamping blank is set as L + 2 × 5mm = L + 10mm, and the width is set as W + 2 × 3mm = W + 6mm.

[0061] In one example, the fabric used for the reinforcement of the vehicle's front hood latch is analyzed and explained. See [link / reference] Figure 2As shown, in the prior art, the rectangular stamped blank corresponding to the front cover locking pin reinforcement has a length of L1 and a width of W1. After being divided using the material distribution method of the stamped forming component described in this invention, a main component 1 and eight auxiliary components 2 connected to the main component 1 are obtained. Since the auxiliary components 2 are connected in the width direction of the main component 1, the material of the main component 1 will be reduced relative to the width direction of the existing front cover locking pin reinforcement after being divided by the dividing contour line 3. After division, the rectangular stamped blank corresponding to the front cover locking pin reinforcement has a length of L2 and a width of W2, and correspondingly: L1=L2, W1>W2. See also Figure 2 As shown, after dividing the smaller unfolded material, i.e., accessory component 2, the dimensions reduced in the width direction of the unfolded material are x1 and x2. The total material reduction in the width direction is x1 + x2. The final unfolded material of the main component is as follows. Figure 3 The material saved is the material size that is reduced in width while maintaining the same length. According to... Figure 2 The dimensions x1+x2 shown are 30%~40% of W1, which means that the material utilization rate of this example is increased by 30%~40%.

[0062] In another example, the fabric of the rear seat reinforcement panel in a vehicle will be analyzed and explained. (Participate) Figure 3 As shown, in the prior art, the rectangular stamped blank corresponding to the rear seat reinforcement plate has a length of L3 and a width of W3. After being divided using the material distribution method of the stamped forming component described in this invention, a main component 1 and two auxiliary components 2 connected to the main component are obtained. Since the auxiliary components 2 are connected along the length of the main component 1, the material consumption of the main component 1 will decrease relative to the length of the existing front cover lock pin reinforcement after being divided by the outline. After division, the rectangular stamped blank corresponding to the rear seat reinforcement plate has a length of L4 and a width of W4, and correspondingly: L3 > L4, W3 = W4.

[0063] As a preferred embodiment of the present invention, the material distribution method for the stamped forming component of the present invention further includes, after dividing the component into several auxiliary components connected to the main component by taking the dividing contour line and the coincidence line of the stamped forming component as the boundary, verifying the stress distribution of the main component and auxiliary components after the division by finite element analysis, and optimizing the dividing contour line based on the stress distribution results.

[0064] For example, if the stress distribution cloud map shows excessive stress concentration in certain areas, it may lead to defects such as cracking and deformation in the stamped parts. In this case, it is necessary to adjust the segmentation contour lines. For instance, if severe stress concentration is found at the connection between the auxiliary component and the main component, the segmentation contour lines can be adjusted appropriately to make the transition at the connection smoother, increase the connection area, and thus disperse the stress. Through multiple simulations and adjustments, until the stress distribution meets the quality requirements of the stamped parts, the reliability and stability of the entire stamping process are ensured.

[0065] This invention verifies the stress distribution and optimizes the segmentation contour through finite element analysis, further ensuring the quality of stamped parts and improving the scientificity and practicality of the entire fabric application method.

[0066] In one embodiment, see Figure 4 As shown, the present invention also provides a method for manufacturing a stamped component, comprising:

[0067] A stamping blank is provided, which is divided into sections according to the above-described method for laying out stamped components. The stamping blank includes a stamping area for the main component and a stamping area for auxiliary components located in the stamping scrap area of ​​the main component.

[0068] The stamping blank is stamped to obtain the main component and several auxiliary components.

[0069] Several of the auxiliary components are fixedly connected to the main component to obtain a stamped component.

[0070] This invention divides the stamping blank into zones according to a specific material distribution method, setting up stamping areas for main components and stamping areas for auxiliary components. This fully utilizes the waste area from the main component stamping for the manufacture of auxiliary components. In traditional processes, waste is often discarded, while this method achieves waste reuse, improving material utilization and reducing material costs. Furthermore, this zoning method allows for precise control of the blank size, avoiding the need to increase the overall blank size to meet the manufacturing requirements of auxiliary components, thus reducing unnecessary material consumption. Simultaneously, by pre-dividing the blank, the stamping areas for each component (main component and auxiliary component) are clearly defined, providing clear planning for subsequent stamping and assembly processes. During the stamping process, the die can be specifically designed and adjusted for different areas, improving stamping efficiency and accuracy while reducing die adjustment time.

[0071] Stamping the partitioned blank is the core step in transforming it into the required main and auxiliary components. By setting appropriate stamping process parameters, such as stamping speed, pressure, and die clearance, the quality of the formed components is ensured. It should be noted that components in different regions may require different stamping processes due to variations in shape, size, and functional requirements. For example, main components, which bear the primary load, may require higher stamping pressure to ensure material strength and forming accuracy; auxiliary components, on the other hand, can have their process parameters adjusted according to their characteristics to improve production efficiency.

[0072] In one example, the manufacturing method of the vehicle front hood lock pin reinforcement is analyzed and explained.

[0073] See Figure 6 As shown, in the prior art, the rectangular blank used for stamping completely covers the unfolded plane of the front cover locking pin reinforcement, resulting in a relatively large size. The rectangular blank is then subjected to blanking, forming, and punching processes sequentially to obtain the front cover locking pin reinforcement part.

[0074] See Figure 7 As shown, in this invention, the rectangular blank for stamping only covers the unfolded plane of the main component of the front cover locking pin reinforcement, and the internal scrap area of ​​the stamping blank corresponding to the main component is used as the stamping blank of the auxiliary component. Compared with the prior art, the size of the stamping blank is smaller, which improves the material utilization rate.

[0075] In another example, the manufacturing method of a rear seat reinforcement panel in a vehicle is analyzed and explained. See [link / reference] Figure 8 As shown, the rear seat reinforcement plate is first divided according to preset rules to obtain the main component and auxiliary component. Then, the stamping blank size is determined by the size of the main component. The external scrap area of ​​the stamping blank corresponding to the main component is used as the stamping blank of the auxiliary component. Compared with the existing technology, the stamping blank size is smaller, which improves the material utilization rate.

[0076] See Figure 6 As shown, in the prior art, the rectangular blank used for stamping completely covers the unfolded plane of the front cover locking pin reinforcement, resulting in a relatively large size. The rectangular blank is then subjected to blanking, forming, and punching processes sequentially to obtain the front cover locking pin reinforcement part.

[0077] Furthermore, the auxiliary components are fixed to the main components by welding, screwing, gluing, or riveting.

[0078] Welding provides high-strength connections and is suitable for applications requiring extremely high structural strength and relatively stable connections, such as connection points in automotive frames. Welding can achieve 80% to 90% of the strength of the base material. Threaded connections offer the advantage of disassembly, facilitating later maintenance and component replacement. They are widely used in the connection of stamped parts in equipment requiring frequent maintenance, such as the connection between internal brackets and housings in electronic devices, facilitating disassembly and repair. Adhesive bonding is suitable for structures requiring sealing and subject to relatively low stress, such as the connection of structural components in aircraft cockpits in the aerospace field. It effectively prevents gas or liquid leakage while also providing some cushioning and shock absorption. Riveting is characterized by its ease of operation and reliable connection. It is highly adaptable to connecting components of different materials and is commonly used in the connection of automotive body panels and reinforcing ribs, capable of withstanding significant shear and tensile forces.

[0079] Furthermore, the main component and the auxiliary component are provided with a first overlapping portion at the corresponding connection position, and the auxiliary component is provided with a second overlapping portion that corresponds to and cooperates with the first overlapping portion.

[0080] This design significantly increases the connection area, thereby improving the stability and reliability of the connection. For example, in automotive body structural components, by rationally designing the size and shape of the lap joint, the fatigue resistance of the connection can be improved by 30% to 40%. During welding, the lap joint provides ample welding space, resulting in a stronger weld. In bolted connections, it increases the effective length of the threaded connection, improving the load-bearing capacity of the thread. In adhesive bonding, the larger lap area enhances adhesive adhesion and increases bond strength. During riveting, the lap joint provides a better anchoring base for the rivet, preventing it from loosening.

[0081] In one embodiment, the present invention provides a vehicle including a stamped component, the stamped component being manufactured using the above-described method for manufacturing stamped components.

[0082] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
