Description

Technical Field

[0001] This application relates to the field of mechanical technology, and in particular to a straightening punching device. Background Technology

[0002] With the increasing demand for lightweight vehicles, automotive structural components are rapidly evolving towards integral molding. The manufacturing process of integrally molded structural components inevitably results in process waste such as material cakes, runners, slag bags, and overflow channels that are integral with the component. This waste must be removed before it can proceed to subsequent processing or assembly stages. Current technologies for removing this process waste primarily involve flame cutting, sawing, or milling. Flame cutting easily leads to localized overheating of the workpiece, causing performance degradation and creating structural weaknesses; sawing is limited by the shape of the workpiece; and milling is difficult to clamp and has very low efficiency.

[0003] Among these, integrally molded thin-walled structural components are increasingly common, and these components typically exhibit varying degrees of deformation after molding. Deformed components require correction before the removal of excess material. Current technology uses presses equipped with correction molds to correct deformation. The mold cavity for the workpiece to be corrected is fixed, but the degree and direction of deformation vary, making it easy to scratch or damage the workpiece during correction.

[0004] In existing technologies, correction and punching are usually completed in two separate processes, and deformed workpieces need to be clamped multiple times and adjusted manually, resulting in significant problems of low production efficiency. Summary of the Invention

[0005] This application provides a correction and punching device that can complete correction and punching by clamping the workpiece in one go, thereby improving production efficiency while ensuring the production quality of structural parts.

[0006] In a first aspect, embodiments of this application provide a punching correction device, the device comprising:

[0007] Base;

[0008] A support member, one end of which is disposed on the base, and the other end of which extends toward a side away from the base;

[0009] A straightening punching die includes a first mounting member, a second mounting member, a first die set, a second die set, a straightening member, and a punching part. The first mounting member is disposed on the base. The second mounting member is movably disposed on the support member and opposite to the first mounting member, and the second mounting member can move closer to or further away from the first mounting member when moving relative to the support member. The first die set and the second die set are both disposed on the side of the first mounting member facing the second mounting member, and the first die set and the second die set are arranged opposite to each other along a first direction, and together define a cavity recessed towards the first mounting member. The cavity is used to accommodate and support the punching part. At least a portion of the structure of one of the first die set and the second die set is movably disposed on the first mounting member relative to the other along the first direction.

[0010] Both the correcting member and the punching member are disposed on the side of the second mounting member facing the first mounting member. The correcting member is configured to correct the shape of the part to be corrected on the part to be punched, and the punching member is configured to cut off the part to be punched on the part to be punched.

[0011] This application provides a corrective punching device, in which a base supports a support member and a corrective punching die, and the support member provides precise guidance for a second mounting member. The second mounting member moves along the support member, and when the second mounting member moves away from the first mounting member, the corrective punching die is in the die-opening process.

[0012] The workpiece to be punched is placed into the cavity formed by the first die set and the second die set. Since at least a portion of the structure of one of the first die set and the second die set is movably disposed on the first mounting member relative to the other in a first direction, at least a portion of the structure of one of the first die set and the second die set can automatically adjust its position according to the shape of the workpiece to be punched, so that the clamping of the workpiece to be punched does not rely on manual adjustment, thereby improving production efficiency.

[0013] When the second mounting component moves towards the first mounting component, it is in the mold closing process. The straightening component contacts the part to be straightened on the part to be punched and straightens it. After straightening, the punching component cuts off the part to be punched on the part to be punched, completing the punching of the part to be punched. By integrating the straightening and punching processes into one, the time for handling, positioning, and clamping the part to be punched is saved, thereby improving work efficiency. Furthermore, the punching process can completely remove the part to be punched, which not only avoids damage to the part to be punched and ensures the performance integrity of the part to be punched, but also allows the part to be punched to be directly recycled, reducing material loss and thus lowering production costs.

[0014] Therefore, the calibration and punching equipment provided in this application integrates the calibration and punching processes into one unit. Calibration and punching can be completed in a single clamping operation, reducing the time spent clamping and transporting the workpiece and significantly improving production efficiency. During calibration, the cavity shape can be automatically adjusted according to the shape of the workpiece, increasing the equipment's flexibility. During punching, the part to be punched can be completely removed and recycled, achieving the effect of reducing production costs.

[0015] In one possible implementation, both the first and second concave mold groups include a plurality of supporting sub-molds, the plurality of supporting sub-molds including the first sub-mold and the second sub-mold;

[0017] Both the first sub-mold and the second sub-mold are movable along the first direction and mounted on the first mounting component.

[0019] The second driving member is connected to the second sub-mold in the second concave mold group to drive the second sub-mold in the second concave mold group to move along the first direction toward one side of the first concave mold group.

[0021] In one possible implementation, both the first sub-mold and the second sub-mold are also magnetically connected to the first mounting component.

[0022] In one possible implementation, the corrective punching die further includes a third concave die group, which is disposed between the first concave die group and the second concave die group along the first direction;

[0023] The third concave die has a third concave cavity, which is used to accommodate and support the workpiece to be punched in the middle edge region of the first direction; the cavity includes the third concave cavity.

[0024] In one possible implementation, the third concave mold group includes two third sub-molds, which are spaced apart along the second direction, and each of the third sub-molds has a sub-inner cavity, the third inner cavity including the two sub-inner cavities;

[0025] The third sub-mold is movably disposed on the first mounting member along the first direction and / or the second direction, wherein the second direction intersects the first direction.

[0026] In one possible implementation, the calibration member includes a calibration part and a mounting part, the mounting part being mounted on the side of the second mounting member facing the first mounting member, the calibration part being connected to the end of the mounting part adjacent to the first mounting member, and the calibration part being movable relative to the mounting part.

[0056] In the description of the embodiments of this application, it should be understood that the terms "comprising" and "having" as used herein, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, display structure, product, or device that includes a step or unit is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0057] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "electrical connection," etc. (if applicable) should be interpreted broadly.

[0058] The terms “left,” “right,” “top,” “bottom,” “inner,” “outer,” etc. (if present) in the specification and claims of this application indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this application.

[0059] The terms "first," "second," "third," "fourth," etc. (if present) in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0060] With the increasing demand for lightweight vehicles, automotive structural components are rapidly evolving towards integral molding. The manufacturing process of integrally molded structural components generates process waste such as sprues, runners, slag bags, and overflow channels. This waste must be removed before it can proceed to subsequent processing or assembly stages.

[0061] Among these, integrally molded thin-walled structural components are increasingly common. The wall thickness of these components is typically only 2-4 mm, leading to significant deformation after molding. Deformed components, if not corrected, are difficult to securely mount, affecting the accuracy of removing excess material. Therefore, deformed components must be corrected before removing excess material.

[0062] In existing technologies, straightening and punching are usually completed in two separate processes, and the handling, positioning, and clamping of structural components all require time. Furthermore, deformation makes it difficult to clamp the structural components, often requiring multiple clamping operations, which is time-consuming, labor-intensive, and affects production efficiency.

[0063] Furthermore, existing technologies typically remove excess material through sawing, laser cutting, or milling. Sawing and milling generate debris that cannot be recycled, resulting in significant material loss and high production costs. Moreover, sawing and milling require removing excess material piece by piece, which is time-consuming, labor-intensive, and inefficient. Laser cutting requires molten material, leading to melt loss, which also increases production costs.

[0064] Therefore, how to improve production efficiency and reduce material waste is a technical problem that urgently needs to be solved.

[0065] In view of this, the present application provides a calibration and punching equipment that integrates the calibration and punching processes into one unit. Calibration and punching can be completed in a single clamping operation of the workpiece 380, reducing the time spent clamping and transporting the workpiece 380 and significantly improving production efficiency. During the calibration process, the cavity shape can be automatically adjusted according to the shape of the workpiece 380, improving the equipment's flexibility. During the punching process, the part to be punched can be completely removed and recycled, achieving the effect of reducing production costs.

[0066] The following description, in conjunction with the accompanying drawings and embodiments, further illustrates the corrective punching equipment provided in this application.

[0067] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 This application provides a correction punching device. The correction punching device includes a base 100, a support member 200, and a correction punching die 300.

[0068] One end of the support member 200 is mounted on the base 100, and the other end of the support member 200 extends toward the side opposite to the base 100. The base 100 provides a support base for the support member 200 and the straightening punching die 300.

[0069] The straightening punching die 300 includes a first mounting member 310, a second mounting member 320, a first die cavity assembly, a second die cavity assembly, a straightening member, and a punching member 360. The first mounting member 310 is disposed on the base 100, and the second mounting member 320 is movably disposed on the support member 200 and opposite to the first mounting member 310. When the second mounting member 320 moves relative to the support member 200, it can move closer to or further away from the first mounting member 310.

[0070] When the second mounting member 320 moves relative to the support member 200 and approaches the first mounting member 310, the calibrating punching die 300 is in the mold closing process. When the second mounting member 320 moves relative to the support member 200 and moves away from the first mounting member 310, the calibrating punching die 300 is in the mold opening process.

[0071] The first die set and the second die set are both located on the side of the first mounting member 310 facing the second mounting member 320. The first die set and the second die set are arranged opposite each other along the first direction X and together define a cavity recessed towards the first mounting member 310. The cavity is used to accommodate and support the workpiece 380 to be punched.

[0072] At least a portion of the structure of one of the first and second die groups is movably disposed on the first mounting member 310 relative to the other along the first direction X.

[0073] When the second mounting member 320 moves away from the first mounting member 310, the correction punching die 300 is in the open state. The part to be punched 380 is placed in the cavity recessed towards the first mounting member 310, which is defined by the first die set and the second die set.

[0074] The part to be punched 380 includes a correction section and a punching section. The correction section is the location where the workpiece to be punched will deform. The punching section consists of process residues such as sprues and slag pockets generated during the integral forming process of the part to be punched 380.

[0075] During the process of the part to be punched 380 contacting the cavity, the part to be corrected of the part to be punched 380 will provide a force to the first die set and the second die set, so that one of the first die set and the second die set moves relative to the other, thereby adjusting the shape of the cavity and forming a cavity that matches the part to be punched 380, so that the part to be punched 380 can be placed in the cavity.

[0076] By having at least a portion of the structure of one of the first and second die assemblies movably mounted on the first mounting member 310 relative to the other along the first direction X, the cavity can automatically adjust according to the shape of the workpiece 380 to be punched, adapting to workpieces 380 of different sizes and degrees of deformation. This eliminates the need for manual adjustment, reduces the difficulty of mounting, and improves both work efficiency and the versatility of the equipment.

[0077] Both the straightening member and the punching member 360 are disposed on the side of the second mounting member 320 facing the first mounting member 310. The straightening member is configured to correct the shape of the portion to be corrected on the part to be punched 380, and the punching member 360 is configured to cut off the portion to be punched on the part to be punched 380. The straightening member can be arranged on the side of the second mounting member 320 facing the first mounting member 310 according to the shape of the part to be punched 380. The punching member 360 can be disposed on the side of the second mounting member 320 facing the first mounting member 310 according to the position of the portion to be punched.

[0078] In this application, the quantity and arrangement of the correction parts and punching parts 360 are not further limited, as long as the correction and punching requirements of the punching parts 380 are met.

[0079] In this application, the shape of the side of the straightening component that contacts the part to be straightened is adapted to the part to be straightened. The shape of the side of the straightening component that contacts the part to be straightened is not further limited; it only needs to meet the straightening requirements of the punched part 380.

[0080] After the workpiece 380 to be punched is placed in the cavity, the second mounting member 320 moves along the support member 200 toward the first mounting member 310. The straightening member first contacts the part to be straightened, and as the second mounting member 320 continues to move, the straightening member applies pressure to the part to be straightened, causing it to be straightened under the constraint of the cavity. During the straightening process, the punching member 360 has not yet come into contact with the workpiece 380 to be punched.

[0081] After the workpiece 380 is aligned, the second mounting member 320 continues to move along the support member 200 toward the first mounting member 310. The punching member 360 cooperates with the first and second die assemblies to provide punching force to the workpiece 380, cutting off the part to be punched.

[0082] The part to be punched is separated from the workpiece 380° by the punching force, resulting in no material loss of debris compared to sawing and milling. Compared to laser cutting, there is no material melting loss, significantly reducing material waste and production costs. Furthermore, the removed part to be punched can be recycled through remelting, further reducing production costs.

[0083] After punching is completed, the second mounting member 320 moves along the support member 200 in a direction away from the first mounting member 310, and the correction and punching member 360 moves with the second mounting member 320. The punched part 380, after correction and punching, remains in the cavity.

[0084] By integrating calibration and punching into one unit, calibration and punching can be completed in a single clamping of the workpiece 380, reducing the time spent clamping and transporting the workpiece 380 and significantly improving production efficiency.

[0085] The present application provides a correction punching device, in which a base 100 provides support for a support member 200 and a correction punching die 300, and the support member 200 provides precise guidance for a second mounting member 320. The second mounting member 320 moves along the support member 200, and when the second mounting member 320 moves away from the first mounting member 310, the correction punching die 300 is in the die opening process.

[0086] The workpiece 380 to be punched is placed into the cavity formed by the first die set and the second die set. Since at least a portion of the structure of one of the first die set and the second die set is movably disposed on the first mounting member 310 relative to the other along the first direction X, at least a portion of the structure of one of the first die set and the second die set can automatically adjust its position according to the shape of the workpiece 380 to be punched, so that the clamping of the workpiece 380 to be punched does not rely on manual adjustment, thereby improving production efficiency.

[0087] When the second mounting part 320 moves toward the first mounting part 310, it is in the mold closing process. The straightening part contacts the part to be straightened on the part to be punched 380 and straightens it. After straightening, the punching part 360 cuts off the part to be punched on the part to be punched 380, completing the punching of the part to be punched 380. By integrating the straightening and punching processes into one, the time for handling, positioning, and clamping the part to be punched 380 is saved, thereby improving work efficiency. Furthermore, the punching process can completely remove the part to be punched, which not only avoids damage to the part to be punched and ensures the performance integrity of the part to be punched, but also allows the part to be punched to be directly recycled, reducing material loss and thus reducing production costs.

[0088] Therefore, the calibration and punching equipment provided in this application integrates the calibration and punching processes into one unit. Calibration and punching can be completed in a single clamping operation on the workpiece 380, reducing the time spent clamping and transporting the workpiece 380 and significantly improving production efficiency. During the calibration process, the cavity shape can be automatically adjusted according to the shape of the workpiece 380, improving the equipment's flexibility. During the punching process, the part to be punched can be completely removed and recycled, achieving the effect of reducing production costs.

[0089] For example, a straightening punching device provided in this application embodiment can be driven by a hydraulic press.

[0090] The hydraulic press includes a main cylinder 600, a top beam 700, and a movable crossbeam 800. One end of the support member 200, facing away from the base 100, is connected to the top beam 700. A second mounting member 320 is located on the side of the movable crossbeam 800 facing the first mounting member 310, and the movable crossbeam 800 can move along the support member 200. One end of the main cylinder 600 is mounted on the top beam 700, and the other end is mounted on the movable crossbeam 800. The main cylinder 600 drives the movable crossbeam 800 to move along the support member 200, thereby causing the second mounting member 320 to move along the support member 200.

[0091] Specifically, the first mounting member 310 is connected to the base 100 via the first mounting plate 311, and the second mounting member 320 is connected to the movable crossbeam 800 via the second mounting plate 321. For example, the second mounting plate 321 has mounting holes; one side of the second mounting plate 321 can be connected to the movable crossbeam 800 via a T-bolt, and the other side can be connected to the second mounting member 320 via countersunk screws. Furthermore, the second mounting member 320 may also have stepped holes for mounting the straightening member and the punching member 360.

[0092] An elastic element, such as a disc spring 900, may be provided between the calibrator and the second mounting member 320. One end of the disc spring 900 is connected to the side of the second mounting member 320 facing the first mounting member 310, and the other end is connected to the end of the calibrator away from the first mounting member 310.

[0093] When the workpiece 380 is being straightened and punched, the master cylinder 600 drives the movable crossbeam 800 to move along the support member 200 toward the first mounting member 310, thereby causing the second mounting member 320 to move along the support member 200 toward the first mounting member 310. As the straightening member gradually comes into contact with the workpiece 380, the straightening member applies pressure to the part to be straightened, thereby straightening the part.

[0094] After the part to be calibrated is calibrated, the part to be punched 380 does not need to be disassembled. The main cylinder 600 continues to drive the movable crossbeam 800 to move along the support 200 toward the first mounting member 310, thereby driving the second mounting member 320 to continue moving along the support 200 toward the first mounting member 310. The calibrator compresses the disc spring 900, and the calibrator moves away from the first mounting member 310 relative to the part to be punched 360. The calibrator continues to move toward the first mounting member 310 until the part to be punched is cut off.

[0095] By compressing the disc spring 900, the process of straightening is transformed into a punching process, integrating straightening and punching into a single stamping stroke. This eliminates the need for disassembly, re-clamping, and transfer of the workpiece 380 to be punched, significantly improving production efficiency.

[0096] In addition, the first mounting plate 311 may be provided with a support rod 312, and the second mounting plate 321 may be provided with a corresponding sleeve 322, which is fitted onto the support rod 312. When the movable crossbeam 800 drives the second mounting plate 321 to move along the support member 200, the support rod 312 and the sleeve 322 cooperate to achieve extension and retraction. The second mounting member 320 may also be provided with a through hole for installing the sleeve 322.

[0097] The cooperation between the support rod 312 and the sleeve 322 can further ensure the stability of the equipment and prevent the movement direction of the second mounting part 320 from deviating, thereby ensuring the accuracy of correction and punching.

[0098] In some embodiments of this application, the first concave mold group and the second concave mold group both include a plurality of supporting sub-molds, the plurality of supporting sub-molds including the first sub-mold 330 and the second sub-mold 340.

[0099] A first sub-mold 330 and a second sub-mold 340 are sequentially arranged along a second direction Y. The first sub-mold 330 has a first concave cavity 331, which is used to accommodate and support the corner portion of the workpiece 380 to be punched in the second direction Y. The second sub-mold 340 has a second concave cavity 341, which is used to accommodate and support the middle portion of the workpiece 380 to be punched in the second direction Y. The second direction Y intersects with the first direction X. The cavity includes the first concave cavity 331 and the second concave cavity 341.

[0100] Both the first sub-mold 330 and the second sub-mold 340 are movable along the first direction X and mounted on the first mounting member 310.

[0101] For example, before the workpiece 380 is corrected and punched, the operator can arrange the first sub-die 330 and the second sub-die 340 according to the contour of the workpiece 380. The first concave cavity 331 and the second concave cavity 341 together form a cavity for accommodating the workpiece 380.

[0102] The first concave cavity 331 accommodates and supports the corner portion of the workpiece 380 to be punched in the second direction Y. The corner portion of the workpiece 380 is a stress concentration area and is most prone to deformation. The first concave cavity 331 can provide reinforced support for this area, effectively resisting uneven stress and preventing corner deformation.

[0103] Meanwhile, the first sub-mold 330 can also be positioned according to the location of the part to be punched. On the first mounting member 310, the first sub-mold 330 is positioned corresponding to the location of the part to be punched 380. On the second mounting member 320, a punching member 360 is positioned corresponding to the first sub-mold 330. The punching member 360 provides punching force to the part to be punched, and the first sub-mold 330 supports the part to be punched, facilitating its removal and preventing deformation of the part to be punched 380.

[0104] The second concave cavity 341 accommodates and supports the part 380 to be punched in the middle part of the second direction Y. The second concave cavity 341 cooperates with the first concave cavity 331 to provide sufficient support for the part 380 to be punched, avoiding deformation due to insufficient support.

[0105] The surfaces of the first concave cavity 331 and the second concave cavity 341 that contact the workpiece 380 to be punched are adapted to the surface of the workpiece 380 at that position.

[0106] Furthermore, the cavity can be larger than the outer contour of the workpiece 380 to be punched. For example, the contour formed by the cavity can be 1-10mm larger than the outer contour of the workpiece 380 to be punched, allowing for coarse positioning of the workpiece 380, accelerating the clamping speed, and thus improving production efficiency. Additionally, the small gap between the cavity and the outer contour of the workpiece 380 can prevent collisions between the first and second die assemblies and the workpiece 380, thereby avoiding unnecessary deformation or damage.

[0107] When the workpiece 380 is placed, the deformation locations of the workpiece 380 may differ, therefore the cavity may not match the shape of the workpiece 380. Both the first sub-mold 330 and the second sub-mold 340 are movable along the first direction X on the first mounting member 310. When the workpiece 380 contacts the cavity, the deformation location of the workpiece 380 provides a force to the first sub-mold 330 and the second sub-mold 340. This force can be decomposed into forces in the first direction X and the third direction Z. The first sub-mold 330 and the second sub-mold 340, subjected to the force in the first direction X, automatically adjust their positions to form a cavity that conforms to the shape of the workpiece 380.

[0108] By automatically adjusting the position of the first sub-mold 330 and the second sub-mold 340, the tedious mold adjustment process is eliminated, the clamping process of the part to be punched 380 is simplified, the clamping time is reduced, and thus production efficiency is improved.

[0109] In some embodiments of this application, the straightening punching device further includes a first drive member 400 and a second drive member 500. The first drive member 400 is connected to a second sub-die 340 in the first die assembly to drive the second sub-die 340 in the first die assembly to move along a first direction X toward one side of the second die assembly. The second drive member 500 is connected to a second sub-die 340 in the second die assembly to drive the second sub-die 340 in the second die assembly to move along the first direction X toward one side of the first die assembly.

[0110] For example, when the part to be punched 380 is placed into the cavity formed by the first die set and the second die set, it is only for coarse positioning.

[0111] Both the first driving component 400 and the second driving component 500 can be horizontal power cylinders, such as hydraulic cylinders, pneumatic cylinders, etc. The second sub-mold 340 in the first die assembly is connected to a horizontal power cylinder, and the second sub-mold 340 in the second die assembly is also connected to a horizontal power cylinder.

[0112] A horizontal power cylinder extends, pushing the second sub-die 340 in the first die assembly to move towards one side of the second die assembly, so that the second sub-die 340 in the first die assembly is pressed against the workpiece 380 to be punched. Similarly, another horizontal power cylinder extends, pushing the second sub-die 340 in the second die assembly to move towards one side of the first die assembly, so that the second sub-die 340 in the second die assembly is pressed against the workpiece 380 to be punched.

[0113] When the horizontal power cylinder pushes the second sub-die 340 in the first die set and the second die set, the workpiece 380 to be punched will rotate slightly, thereby causing the first sub-die 330 in the first die set and the second die set to move along with the workpiece 380, so that the formed cavity adapts to the shape and position of the workpiece 380. Through the cooperation of the horizontal power cylinder and the second sub-die 340, the precise positioning of the workpiece 380 to be punched is achieved, thereby enhancing the accuracy of correction and punching.

[0114] In some embodiments of this application, the second sub-mold 340 has a first magnetic member 342, which is magnetically connected to the first driving member 400 or the second driving member 500.

[0115] For example, the second sub-mold 340 in the first concave mold group has a first magnetic absorbing member 342 on the side facing the first driving member 400, and the second sub-mold 340 in the second concave mold group has a first magnetic absorbing member 342 on the side facing the second driving member 500.

[0116] When the first driving member 400 extends, it magnetically attracts the second sub-die 340 in the first die assembly, thereby driving the second sub-die 340 in the first die assembly to move precisely toward the direction of the second die assembly until it is in close contact with the part to be punched 380.

[0117] Similarly, when the second driving member 500 extends, it magnetically attracts the second sub-mold 340 in the second concave die group, thereby driving the second sub-mold 340 in the second concave die group to move precisely toward the direction of the first concave die group until it is in close contact with the part to be punched 380.

[0118] After the position of the second sub-mold 340 is adjusted, the first drive component 400 and the second drive component 500 remain extended, and the second sub-mold 340 cannot move, thus ensuring accurate positioning of the workpiece 380 to be punched.

[0119] The connection or separation of the second sub-mold 340 with the first driving component 400 or the second driving component 500 can be completed quickly through the first magnetic suction component 342. Compared with the traditional technology of fixing with bolts, the adjustment time is significantly shortened and the production efficiency is improved.

[0120] In some embodiments of this application, the first sub-mold 330 and the second sub-mold 340 are also magnetically connected to the first mounting member 310.

[0121] For example, the first sub-mold 330 and the second sub-mold 340 have a second magnetic chuck 332 on the side facing the first mounting member 310. Before the alignment and punching begin, the operator positions the first sub-mold 330 and the second sub-mold 340 according to the shape of the part 380 to be punched and the position of the part to be punched. The first sub-mold 330 and the second sub-mold 340 are magnetically attracted to the first mounting member 310, achieving pre-fixation. By using the magnetic attraction of the second magnetic chuck 332 instead of bolt fastening, the clamping time is significantly reduced, thereby improving production efficiency.

[0122] The second magnetic chuck 332 allows the first sub-mold 330 and the second sub-mold 340 to be connected to the first mounting component 310, preventing them from sliding or tipping over before precise positioning. While ensuring a certain level of stability for the first and second sub-molds 330 and 340, it also allows them to slide on the first mounting component 310, automatically adjusting to the shape of the workpiece 380 to be punched, thus enhancing the equipment's versatility.

[0123] The first magnetic attractor 342 and the second magnetic attractor 332 can be electromagnets or permanent magnets. In this application, the types of the first magnetic attractor 342 and the second magnetic attractor 332 are not further limited, as long as they can enable the first sub-mold 330 and the second sub-mold 340 to be magnetically connected to the first mounting member 310.

[0124] Furthermore, compared to traditional technology that uses bolts for fixing, the first sub-mold 330 and the second sub-mold 340 are connected to the first mounting component 310 via the second magnetic 332. Operators only need to apply a force greater than the magnetic attraction force to disassemble the first sub-mold 330 and the second sub-mold 340, which significantly reduces the difficulty and time of disassembly, thereby improving production efficiency.

[0125] In some embodiments of this application, the correcting punching die 300 further includes a third concave die group, which is disposed between the first concave die group and the second concave die group along the first direction X.

[0126] The third concave die assembly has a third concave cavity, which is used to accommodate and support the workpiece 380 to be punched in the middle edge region of the first direction X.

[0127] The cavity includes a third recessed cavity. The third recessed die assembly, together with the first and second recessed die assemblies, forms a cavity adapted to the workpiece 380 to be punched. The third recessed cavity provides support for the middle edge region of the workpiece 380 in the first direction X, preventing the workpiece 380 from being unsupported in the middle edge region of the first direction X when the straightening and punching parts 360 come into contact with it. This would make the region prone to deformation, resulting in a reduction in the flatness of the workpiece 380 after straightening and punching.

[0128] Furthermore, the third concave die forms a cavity that is adapted to the middle edge region of the workpiece 380 in the first direction X, which further provides a positioning reference for the mounting of the workpiece 380 and improves the stability of the workpiece 380 during the correction and punching process.

[0129] In some embodiments of this application, the third concave mold group includes two third sub-molds 370, the two third sub-molds 370 are spaced apart along the second direction Y, and each of the third sub-molds 370 has a sub-inner cavity, the third inner cavity including two sub-inner cavities.

[0130] The third sub-mold 370 is movable along the first direction X and / or the second direction Y and is mounted on the first mounting member 310, wherein the second direction Y intersects the first direction X.

[0131] For example, two third sub-dies 370 are placed between the first die set and the second die set. The two third sub-dies 370 are spaced apart along the second direction Y to form a third inner cavity. The surface of the third inner cavity that contacts the workpiece 380 is adapted to the workpiece 380 and supports both sides of the workpiece 380 in the second direction Y.

[0132] The third sub-die 370 can move in the second direction Y to match the dimensions of the workpiece 380 to be punched, thus supporting the workpiece 380. The third sub-die 370 can also move in the first direction X. By adjusting its position in the first direction X, the support position of the third sub-die 370 on the workpiece 380 is optimized, achieving the best support effect. Of course, it is understandable that the third sub-die 370 can move simultaneously in both the first direction X and the second direction Y, ensuring both effective support and precise positioning of the workpiece 380.

[0133] In addition, the third sub-mold 370 can also be magnetically connected to the first mounting member 310. Lubricating oil, lubricating powder, etc. can also be provided between the first sub-mold 330, the second sub-mold 340, and the third sub-mold 370 and the first mounting member 310 to reduce friction and improve the flexibility of adjusting the position of the first sub-mold 330, the second sub-mold 340, and the third sub-mold 370.

[0134] The straightening and punching equipment can also be equipped with two horizontal power cylinders corresponding to the two third sub-dies 370 respectively. The four horizontal power cylinders drive the two second sub-dies 340 and the two third sub-dies 370 in sequence, adjusting their positions so that the cavity formed by the first sub-dies 330, the second sub-dies 340 and the third sub-dies 370 is in close contact with the workpiece 380 to be punched, thereby achieving precise positioning and improving the accuracy of straightening and punching.

[0135] For example, see Figure 7 and Figure 8 The part to be punched, 380, can be an aluminum alloy subframe casting, which has 11 ingates and 18 slag traps.

[0136] The second mounting component 320 is provided with 29 straightening members and 29 punched members 360. The side of the straightening member closest to the aluminum alloy subframe casting has a concave surface that matches the side of the aluminum alloy subframe casting facing the second mounting component 320. The height of the straightening member in the third direction Z is five millimeters higher than that of the punched members 360.

[0137] On the first mounting member 310, 29 first sub-dies 330 are provided corresponding to the punching member 360. In the first direction X, two second sub-dies 340 are provided on both sides of the aluminum alloy subframe casting on the first mounting member 310, and the two second sub-dies 340 are located in the middle area of ​​the aluminum alloy subframe casting in the second direction Y. In the second direction Y, two third sub-dies 370 are provided on both sides of the aluminum alloy subframe casting on the first mounting member 310, and the two third sub-dies 370 are located in the middle area of ​​the aluminum alloy subframe casting in the first direction X.

[0138] The first sub-mold 330, the second sub-mold 340, and the third sub-mold 370 together form a cavity that accommodates and supports the aluminum alloy subframe casting. The first sub-mold 330, the second sub-mold 340, and the third sub-mold 370 are all magnetically connected to the first mounting component 310.

[0139] The straightening and punching equipment is equipped with four horizontal hydraulic cylinders corresponding to the two second sub-dies 340 and the two third sub-dies 370, with a thrust of 10 tons per cylinder. The four horizontal hydraulic cylinders are activated sequentially, pushing the two second sub-dies 340 and the two third sub-dies 370 in turn, so that the aluminum alloy subframe casting is tightly attached to the cavity.

[0140] The hydraulic press is started, and the thrust of the main cylinder 600 reaches 315 tons. The main cylinder 600 drives the movable crossbeam 800 to move towards the first mounting component 310, thereby driving the second mounting component 320 to move towards the first mounting component 310. The 29 straightening components first contact the deformed parts of the aluminum alloy subframe casting, applying pressure to the deformed areas until straightening is complete. After straightening, the aluminum alloy subframe casting does not need to be removed, and the second mounting component 320 continues to move towards the first mounting component 310. The 29 straightening components compress the disc springs 900, causing relative movement with the 29 punching components 360, which continue to move towards the first mounting component 310. After contacting the ingate and slag collection bag, the 29 punching components 360 cut and break them, separating them from the aluminum alloy subframe casting.

[0141] For example, see Figure 9 and Figure 10 The part to be punched 380 can be an aluminum alloy battery tray casting, which has 18 ingates and 39 slag collection bags.

[0142] The second mounting member 320 is provided with 57 straightening members and 57 punched members 360. The side of the straightening member near the aluminum alloy battery tray casting has a concave surface that matches the side of the aluminum alloy battery tray casting facing the second mounting member 320. The height of the straightening member in the third direction Z is 10 mm higher than that of the punched members 360.

[0143] On the first mounting member 310, 57 first sub-dies 330 are provided corresponding to the punching member 360. In the first direction X, two second sub-dies 340 are provided on both sides of the aluminum alloy battery tray casting on the first mounting member 310, and the two second sub-dies 340 are located in the middle area of ​​the aluminum alloy battery tray casting in the second direction Y. In the second direction Y, two third sub-dies 370 are provided on both sides of the aluminum alloy battery tray casting on the first mounting member 310, and the two third sub-dies 370 are located in the middle area of ​​the aluminum alloy battery tray casting in the first direction X.

[0144] The first sub-mold 330, the second sub-mold 340, and the third sub-mold 370 together form a cavity that accommodates and supports the aluminum alloy battery tray casting. The first sub-mold 330, the second sub-mold 340, and the third sub-mold 370 are all magnetically connected to the first mounting member 310.

[0145] The straightening and punching equipment is equipped with four horizontal hydraulic cylinders corresponding to the two second sub-dies 340 and the two third sub-dies 370, with a thrust of 15 tons per cylinder. The four horizontal hydraulic cylinders are activated sequentially, pushing the two second sub-dies 340 and the two third sub-dies 370 in turn, so that the aluminum alloy battery tray casting is tightly attached to the cavity.

[0146] The hydraulic press is started, and the thrust of the main cylinder 600 can reach 500 tons. The main cylinder 600 drives the movable crossbeam 800 to move towards the first mounting part 310, thereby driving the second mounting part 320 to move towards the first mounting part 310. The 57 straightening parts first contact the deformed parts of the aluminum alloy battery tray casting, applying pressure to the deformed parts until straightening is complete. After straightening, the aluminum alloy battery tray casting does not need to be removed, and the second mounting part 320 continues to move towards the first mounting part 310. The 57 straightening parts compress the disc springs 900 and retract, creating relative movement with the 57 punching parts 360. The 57 punching parts 360 continue to move towards the first mounting part 310. After contacting the ingate and slag collection bag, the 57 punching parts 360 cut and break them, separating them from the aluminum alloy battery tray casting.

[0147] For example, see Figure 11 and Figure 12 The part to be punched 380 can be an aluminum alloy rear door track casting, which has 12 ingates and 42 slag collection bags.

[0148] The second mounting component 320 is provided with 54 straightening members and 54 punched members 360. The side of the straightening member near the aluminum alloy rear door track casting has a concave surface that matches the side of the aluminum alloy rear door track casting facing the second mounting component 320. The height of the straightening member in the third direction Z is 10 mm higher than that of the punched members 360.

[0149] On the first mounting component 310, 54 first sub-dies 330 are provided corresponding to the punching component 360. In the first direction X, two second sub-dies 340 are provided on both sides of the aluminum alloy rear door track casting on the first mounting component 310, and the two second sub-dies 340 are located in the middle area of ​​the aluminum alloy rear door track casting in the second direction Y. In the second direction Y, two third sub-dies 370 are provided on both sides of the aluminum alloy rear door track casting on the first mounting component 310, and the two third sub-dies 370 are located in the middle area of ​​the aluminum alloy rear door track casting in the first direction X.

[0150] The first sub-mold 330, the second sub-mold 340, and the third sub-mold 370 together form a cavity that accommodates and supports the aluminum alloy rear door track casting. The first sub-mold 330, the second sub-mold 340, and the third sub-mold 370 are all magnetically connected to the first mounting component 310.

[0151] The straightening and punching equipment is equipped with four horizontal hydraulic cylinders corresponding to the two second sub-dies 340 and the two third sub-dies 370, with a thrust of 10 tons per cylinder. The four horizontal hydraulic cylinders are activated sequentially, pushing the two second sub-dies 340 and the two third sub-dies 370 in turn, so that the aluminum alloy rear door track casting fits tightly against the cavity.

[0152] The hydraulic press is started, and the thrust of the main cylinder 600 can reach 400 tons. The main cylinder 600 drives the movable crossbeam 800 to move towards the first mounting component 310, thereby driving the second mounting component 320 to move towards the first mounting component 310. The 54 straightening components first contact the deformed parts of the aluminum alloy rear door track casting, applying pressure to the deformed parts until the straightening is completed. After the straightening is completed, the aluminum alloy rear door track casting does not need to be removed, and the second mounting component 320 continues to move towards the first mounting component 310. The 54 straightening components compress the disc springs 900 and retract, creating relative movement with the 54 punching components 360. The 54 punching components 360 continue to move towards the first mounting component 310. After the 54 punching components 360 contact the ingate and slag collection bag, they punch and break the ingate and slag collection bag, separating them from the aluminum alloy rear door track casting.

[0153] In summary, the correction punching device provided in this application can adapt to punching parts 380 of different specifications by changing the position, size, and quantity of the first sub-die 330, the second sub-die 340, the third sub-die 370, the correction part, and the punching part 360, as well as the shape of the side of the first sub-die 330, the second sub-die 340, the third sub-die 370, and the correction part that contacts the punching part 380, thus significantly improving the versatility of the correction punching device.

[0154] See Figure 3 In some embodiments of this application, the calibration member includes a calibration part 351 and a mounting part 352. The mounting part 352 is mounted on the side of the second mounting member 320 facing the first mounting member 310. The calibration part 351 is connected to the end of the mounting part 352 adjacent to the first mounting member 310, and the calibration part 351 is movable relative to the mounting part 352.

[0155] For example, the calibration part 351 and the mounting part 352 are connected by a third magnetic member. Specifically, the mounting part 352 is provided with a third magnetic member at one end near the first mounting member 310, and the calibration part 351 is magnetically connected to the mounting part 352 at one end near the mounting part 352.

[0156] As the part to be corrected 380 gradually comes into contact with the correction part 351, if there is a positional deviation between the part to be corrected and the correction part 351, the part to be corrected provides a supporting force to the correction part 351. The supporting force is decomposed into a force perpendicular to the correction part 351 and a force acting laterally on the correction part 351. The lateral force will push the correction part 351 to slide a certain distance relative to the mounting part 352, that is, the correction part 351 automatically adjusts its position until the surface of the part to be corrected 380 is in contact with the correction part 351.

[0157] The master cylinder 600 drives the second mounting member 320 to move along the support member 200 toward the first mounting member 310. The correction member moves with the second mounting member 320, so that the correction part 351 of the correction member applies pressure to the punching part 380. Under the action of pressure, the correction part of the punching part 380 is corrected.

[0158] See Figure 4 In some embodiments of this application, the punching member 360 includes a punching portion 361 and a fixing portion 362. The fixing portion 362 is mounted on the side of the second mounting member 320 facing the first mounting member 310. The punching portion 361 is connected to one end of the fixing portion 362 adjacent to the first mounting member 310, and the punching portion 361 is movable relative to the fixing portion 362.

[0159] For example, the punching portion 361 and the fixing portion 362 can be connected by a fourth magnetic member. Specifically, the fixing portion 362 is provided with a fourth magnetic member at one end near the first mounting member 310, and the punching portion 361 is connected to the fixing portion 362 at one end near the fixing portion 362 by magnetic attraction.

[0160] As the part to be punched 380 gradually comes into contact with the punching part 361, if there is a deviation in the relative position of the part to be punched and the punching part 361, the part to be punched will also provide a supporting force to the punching part 361. The supporting force will be decomposed into a force perpendicular to the correction part 351 and a force acting laterally on the punching part 361. The lateral force will push the punching part 361 to slide a certain distance relative to the fixing part 362, and the punching part 361 will automatically adjust its position until the part to be punched and the punching part 361 are aligned.

[0161] In some embodiments of this application, the first mounting member 310 is movably disposed on the base 100.

[0162] For example, the first mounting member 310 can be connected to the base 100 via the first mounting plate 311. The base 100 may be provided with a mounting groove, and a guide rail 110 is disposed in the mounting groove. The first mounting member 310 is disposed on the side of the guide rail 110 facing the first mounting member 310 via the first mounting plate 311. The guide rail 110 may be a hydraulically floating guide rail 110.

[0163] When the first and second die assemblies are installed, or when the punched part 380, after calibration and punching, is removed, the first mounting part 310 can be removed. At this time, the guide rail 110 can be raised 1-5mm away from the base 100, for example, 1mm, 2mm, 3mm, 4mm, 5mm, etc. The guide rail 110 causes the first mounting plate 311 to separate from the base 100 and rises with the guide rail 110, thereby raising the first mounting part 310. The first mounting part 310 can be moved along the guide rail 110 by a drive component, thereby removing it from the equipment for easy loading and unloading.

[0164] When straightening and punching are performed, the first mounting piece 310 needs to be moved into the equipment. At this time, the drive unit drives the first mounting piece 310 to move along the guide rail 110 and into the equipment. After the first mounting piece 310 is inside the equipment, the guide rail 110 moves toward the base 100 until the surface of the guide rail 110 in contact with the first mounting piece 310 is 0.2-1 mm lower than the surface of the base 100 in contact with the first mounting piece 310, for example, 0.2 mm, 0.3 mm, 0.45 mm, 0.5 mm, 0.8 mm, 1 mm, etc.

[0165] In this application, the distance by which the guide rail is raised or lowered is not further limited, as long as it is convenient for the first mounting component 310 to be moved in or out.

[0166] In summary, see Figure 13 The following is a brief description of the usage process of the punching and straightening device provided in this application:

[0167] S1. Move the first mounting part 310 out of the correction punching equipment.

[0168] S2. Place the first sub-mold 330: According to the projection of the part to be punched on the first mounting part 310, place the first sub-mold 330 corresponding to the number of parts to be punched, and the first sub-mold 330 is magnetically connected to the first mounting part 310.

[0169] S3. Place the second sub-mold 340 and the third sub-mold 370: In the first direction X, place a second sub-mold 340 on each side of the part to be punched 380. The second sub-mold 340 is located in the middle area of ​​the part to be punched 380 in the second direction Y.

[0170] In the second direction Y, a third sub-mold 370 is placed on each side of the workpiece 380 to be punched. The third sub-mold 370 is located in the middle region of the workpiece 380 to be punched in the first direction X, where the first sub-mold 330 is located. Both the second sub-mold 340 and the third sub-mold 370 are magnetically connected to the first mounting member 310.

[0171] S4. Placing the part to be punched 380: The part to be punched 380 is placed in the cavity formed by the first sub-mold 330, the second sub-mold 340, and the third sub-mold 370. During the placement process, the first sub-mold 330, the second sub-mold 340, and the third sub-mold 370 automatically adjust their positions according to the shape and size of the part to be punched 380.

[0172] Move the first mounting part 310 into the straightening and punching equipment.

[0173] Positioning the part to be punched 380: The horizontal power cylinder extends and magnetically connects with the second sub-mold 340 on one side in the first direction X, pushing the second sub-mold 340 to move toward the part to be punched 380 until the second sub-mold 340 is in close contact with the outer wall of the part to be punched 380.

[0174] Next, the horizontal power cylinder on the other side magnetically connects with the second sub-mold 340 on the other side, pushing the second sub-mold 340 towards the workpiece 380 to be punched, until the second sub-mold 340 is in close contact with the outer wall of the workpiece 380 to be punched. This completes the positioning of the workpiece 380 to be punched.

[0175] S5. Correction: Start the hydraulic press. The main cylinder 600 drives the movable crossbeam 800 to move towards the first mounting part 310. The correction part first contacts the workpiece 380 to be punched. The movable crossbeam 800 continues to move towards the first mounting part 310, and the correction part applies pressure to the part to be corrected until the correction is completed.

[0176] S6. Punching: The master cylinder 600 continues to drive the movable crossbeam 800 to move towards the first mounting member 310. The disc spring 900 is compressed, and the straightening member moves away from the first mounting member 310 relative to the punching member 360. The punching member 360 gradually approaches the part to be punched. When the punching member 360 contacts the part to be punched, the part to be punched continues to move towards the first mounting member 310 until the part to be punched is cut off.

[0177] S7. The movable crossbeam 800 moves away from the first mounting part 310, and the straightening part and the punching part 360 separate from the punching part 380 that has completed the straightening and punching.

[0178] S8. Remove the first mounting part 310 from the calibration and punching equipment, take away the punching part 380 that has been calibrated and punched, and recover the cut-off punching part.

[0179] In summary, the calibration and punching equipment provided in this application integrates the calibration and punching processes into one unit. Calibration and punching can be completed in a single clamping operation of the workpiece 380, reducing the time spent clamping and transporting the workpiece 380 and significantly improving production efficiency. During the calibration process, the cavity shape can be automatically adjusted according to the shape of the workpiece 380, improving the equipment's flexibility. During the punching process, the part to be punched can be completely removed and recycled, achieving the effect of reducing production costs.
