Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] The following is combined with Figures 1-7 The present invention describes in detail the pattern-forming mechanism and the stamping die having the same according to embodiments of the present invention.

[0039] Reference Figures 1-7 As shown, the molding mechanism 100 according to an embodiment of the present invention is used for a stamping die. The stamping die includes a stamping punch 200 and a filling punch 300. The filling punch 300 is movable relative to the stamping punch 200. The molding mechanism 100 includes a swing member 1 and a driving member 2. The swing member 1 is adapted to be connected to the stamping punch 200. The swing member 1 is rotatable relative to the stamping punch 200 about a first axis. The driving member 2 is adapted to be connected to the filling punch 300. The filling punch 300 is adapted to drive the driving member 2 to drive the swing member 1 to rotate about the first axis to the pressing position, so that the swing member 1 drives the flanged portion of the stamping part 5 to be opposite to the filling punch 300 in the movement direction of the filling punch 300.

[0040] The forming mechanism 100 is used for stamping dies. The stamping die can be used to manufacture stamped parts 5 with negative angle flanges, such as side panels, fenders, etc. The stamping die includes a stamping punch 200 and a filling punch 300. Both the stamping punch 200 and the filling punch 300 can be located in the lower die of the stamping die. The filling punch 300 is movable relative to the stamping punch 200. The stamping punch 200 can be used to fit with the non-flanged part of the stamped part 5. Before the stamping starts and after the stamping is completed, the filling punch 300 moves to separate from the flanged part of the stamped part 5 to facilitate the picking and putting away of the stamped part 5. During the stamping process, the filling punch 300 can be driven by the upper die of the stamping die to move into the flanged part of the stamped part 5 to support the flanged part, so as to facilitate further forming processing of the flanged part.

[0041] For example, refer to Figure 1 and Figure 2 As shown, the filling punch 300 can move in the front-back direction relative to the stamping punch 200. In the direction of movement of the filling punch 300, one end of the filling punch 300 has a first inclined surface 302, and the other end of the filling punch 300 has an insert 301. Before the stamping starts and after the stamping is completed, the filling punch 300 is driven to a first preset position by an elastic element such as a spring. At this time, the insert 301 separates from the flanged part of the stamped part 5. When the stamping is in progress, the upper die can drive the first inclined surface 302 to move backward when it moves closer to the lower die, so that the filling punch 300 moves backward to a second preset position. At this time, the insert 301 moves into the flanged part of the stamped part 5 to support the flanged part, so as to facilitate further forming processing of the flanged part of the stamped part 5, for example, to flange the part of the stamped part 5 at a position with a smaller flanged angle at a negative angle.

[0042] It should be noted that in the stamping process, the stamped part may have one or more flanging processes (e.g., flanging at the sharp corner of the side taillight, flanging at the overlapping position of the fender, etc.). If the stamped part has already undergone negative angle flanging and needs to undergo negative angle flanging again, after the previous flanging process is completed, the stamped part will experience partial structural springback due to the inability to eliminate internal stress. When the stamped part undergoes negative angle flanging again, the springback of the stamped part will prevent the insert of the filling punch from entering the flanged part. The mating surface of the insert will also fail to fit with the flanged part of the stamped part, making it impossible to perform the subsequent flanging process. This can easily lead to situations such as the insert not entering the negative angle space of the previous process, the upper die deforming the stamped part after it comes down, or the insert deforming the stamped part by pushing it.

[0043] In this embodiment of the invention, the driving member 2 of the molding mechanism 100 can drive the swing member 1 to rotate so that the swing member 1 abuts against the flanged portion of the stamped part 5. The swing member 1 of the molding mechanism 100 can apply a force opposite to the springback direction to the flanged portion of the stamped part 5 to reduce the springback of the stamped part 5. When the swing member 1 rotates to the pressing position, through the action of the swing member 1 on the flanged portion, the flanged portion of the stamped part 5 can be made to face the filling punch 300 in the movement direction of the filling punch 300, so as to ensure that the insert 301 on the filling punch 300 can accurately enter the flanged portion of the stamped part 5 to complete the subsequent flanged process.

[0044] The forming mechanism 100 includes a swing member 1 and a driving member 2. The swing member 1 can be installed on the stamping punch 200. The swing member 1 is rotatable relative to the stamping punch 200 about a first axis. The swing member 1 can be provided with a first mounting hole. The first axis coincides with the axis of the first mounting hole. The swing member 1 can be rotatably connected to the stamping punch 200 through a pin passing through the first mounting hole.

[0045] The driving component 2 is suitable for connection with the filling punch 300. The connection method between the driving component 2 and the filling punch 300 can be reasonably set according to the actual situation, as long as it ensures that the driving component 2 and the filling punch 300 can be stably and reliably connected. As some embodiments of this application, the driving component 2 can be fixedly connected to the filling punch 300. The connection method between the driving component 2 and the filling punch 300 can be a snap-fit ​​connection, a welded connection, or a bolted connection, etc. Snap-fit ​​connections, welded connections, or bolted connections have simple structures and are easy to disassemble and assemble, which helps to reduce assembly difficulty. As some other embodiments of this application, the driving component 2 and the filling punch 300 can be integrally formed. That is, the driving component 2 and the filling punch 300 can be constructed as an integrally formed part. The integrally formed part has good structural strength. By making the driving component 2 and the filling punch 300 integrally formed, the connection reliability between the driving component 2 and the filling punch 300 can be improved, and the probability of breakage at the connection between the driving component 2 and the filling punch 300 can be reduced.

[0046] The filling punch 300 is adapted to drive the driving member 2 to drive the swing member 1 to rotate around the first axis to the pressing position. That is, when the filling punch 300 moves relative to the stamping punch 200, the filling punch 300 can drive the driving member 2 to move, so that the driving member 2 drives the swing member 1 to rotate around the first axis to the pressing position. When the swing member 1 rotates to the pressing position, the swing member 1 can rotate to insert into the flanged part of the stamping part 5 and hook downwards onto the flanged part of the stamping part 5 to reduce the upward springback of the stamping part 5. At this time, in the direction of movement of the filling punch 300, the flanged part of the stamping part 5 is opposite to the filling punch 300 to ensure that the insert 301 on the filling punch 300 can accurately enter into the flanged part of the stamping part 5.

[0047] In the above embodiment, the filling punch 300 is adapted to drive the drive member 2 to drive the swing member 1 to rotate around the first axis to the pressing position, so that the swing member 1 drives the flanged part of the stamped part 5 to be opposite to the filling punch 300 in the movement direction of the filling punch 300, thereby ensuring that the insert 301 on the filling punch 300 can accurately enter the flanged part of the stamped part 5, so as to improve the yield of the stamped part 5.

[0048] In some embodiments of the present invention, such as Figures 4-7 As shown, the ornament 1 includes a connected body part 11 and a swing rod part 12. A first axis passes through the body part 11, and the swing rod part 12 is adapted to abut against the inner wall of the flanged part.

[0049] The pendulum component 1 includes a body portion 11 and a pendulum rod portion 12. In some embodiments of the invention, the body portion 11 and the pendulum rod portion 12 can be separate components, fixedly connected. The connection method between the body portion 11 and the pendulum rod portion 12 can be welding, snap-fit, or bolted. In other embodiments of the invention, the body portion 11 and the pendulum rod portion 12 can be integrally molded. By constructing the body portion 11 and the pendulum rod portion 12 as an integrally molded part, the structural strength of the body portion 11 and the pendulum rod portion 12 can be increased, the stress at the connection point of the body portion 11 and the pendulum rod portion 12 can be reduced, and the processing difficulty of the body portion 11 and the pendulum rod portion 12 can be reduced.

[0050] The main body 11 may be constructed with a first mounting hole, and the first axis coincides with the axis of the first mounting hole. That is, the first axis passes through the first mounting hole of the main body 11. The main body 11 can rotate around the first axis. When the main body 11 rotates around the first axis, the rocker arm 12 also rotates around the first axis synchronously. When the rocker arm 1 rotates to the pressing position, the rocker arm 12 is adapted to abut against the inner wall of the flanged part of the stamped part 5. The rocker arm 12 can apply a force to the flanged part of the stamped part 5. Specifically, the rocker arm 12 can apply a downward force to the flanged part of the stamped part 5 so that the flanged part of the stamped part 5 will produce a downward displacement, thereby ensuring that the insert 301 enters into the flanged part of the stamped part 5 and completes the subsequent flanged process.

[0051] In some embodiments of the present invention, such as Figures 4-7 As shown, the driving component 2 has a guide surface 20, and the swing component 1 is provided with a guide component 13 suitable for guiding and cooperating with the guide surface 20.

[0052] Among them, the surface of the driving component 2 facing the swing component 1 has a guide surface 20. The guide surface 20 can form a height difference along the movement direction of the filling punch 300. The guide component 13 is adapted to maintain a guiding engagement state with the guide surface 20. When the filling punch 300 moves, the filling punch 300 drives the guide surface 20 of the driving component 2 to move, so that the guide component 13 on the swing component 1 abuts with the guide surface 20 at different positions. By setting the height difference shape of the guide surface 20, the swing component 1 can be rotated by driving the guide component 13 through the guide surface 20 when the guide surface 20 moves.

[0053] In the above embodiment, by setting a guide member 13 and a driving member 2 that can be guided and matched, the guide member 13 can be displaced in the vertical direction according to the height difference of the guide surface 20 of the driving member 2, so as to drive the swing member 1 to rotate. The guide member 13 and the driving member 2 that are guided and matched have a simple structure, stable matching, and reliable driving effect.

[0054] In some embodiments of the present invention, such as Figures 4-7 As shown, the guide member 13 is constructed as a roller 131, and the rotation axis of the roller 131 is parallel to the first axis.

[0055] The guide member 13 can be constructed as a roller 131, which can roll on the guide surface 20. That is, the filling punch 300 is moved in the front-to-back direction by the force of the stamping punch 200. The filling punch 300 drives the driving member 2 to move in the front-to-back direction, and then the roller 131 rolls on the guide surface 20. When the guide area of ​​the guide surface 20 is non-planar, the roller 131 generates an upward displacement while rolling. At the same time, the swing member 1 rotates around the first axis until the swing rod part 12 abuts against the flanged part of the stamping part 5 and drives the flanged part of the stamping part 5 to move downward. This realizes the adjustment of the spatial position of the flanged part of the stamping part 5 so that the insert 301 can enter the negative angle flange. By constructing the guide member 13 as a roller 131, the friction between the guide member 13 and the guide surface 20 can be reduced. At the same time, the wear of the guide member 13 during the working process can be reduced, so that the stamping die has better structural stability and is conducive to extending the service life of the guide member 13.

[0056] The roller 131 has a second axis, which is parallel to the first axis. When the roller 131 rolls on the guide surface 20, the roller 131 will generate displacement in the vertical direction. By making the second axis parallel to the first axis, the roller 131 drives the swing piece 1 to rotate around the first axis, so that the swing piece 1 can rotate into the flanged part of the stamped part 5 and hook downwards onto the flanged part of the stamped part 5, thereby completing the subsequent flanged process.

[0057] In some other embodiments of the present invention, the guide member 13 is constructed as a guide rod (not shown in the figure). The guide rod abuts against the guide surface 20 and can slide on the guide surface 20. The filling punch 300 is moved in the front-back direction by the force of the stamping punch 200. The filling punch 300 drives the driving member 2 to move in the front-back direction, and the guide rod can slide on the guide surface 20. The swing member 1 rotates around the first axis until the swing rod part 12 abuts against the flanged part of the stamping part 5 and drives the flanged part of the stamping part 5 to move downward. This allows the spatial position of the flanged part of the stamping part 5 to be adjusted so that the insert 301 can enter the negative angle flange. By constructing the guide member 13 as a guide rod, the structure of the guide member 13 can be simplified, which is beneficial to the part processing of the guide member 13 and the assembly of the guide member 13, thereby improving production efficiency.

[0058] In some embodiments of the present invention, such as Figures 4-7 As shown, the guide surface 20 includes a first guide area 21, a second guide area 22 and a third guide area 23 arranged sequentially along a first direction. The filling punch 300 is adapted to drive the drive member 2 to move in the front-back direction. When the guide member 13 moves from the first guide area 21 to the second guide area 22, the swing member 1 rotates towards the position of the pressing member. When the guide member 13 is guided and engaged with the second guide area 22, the swing member 1 remains in the position of the pressing member. When the guide member 13 is guided and engaged with the third guide area 23, the swing member 1 separates from the stamped member 5.

[0059] The guide surface 20 includes a first guide area 21, a second guide area 22 and a third guide area 23 arranged sequentially in the front-back direction. In the vertical direction, the second guide area 22 is higher than the first guide area 21 and the third guide area 23, and the first guide area 21 and the third guide area 23 can be tilted downward relative to the second guide area 22.

[0060] Before stamping begins, the axis of guide member 13 is located below the first axis. During stamping, as follows: Figure 5 As shown, the driving component 2 moves from front to back with the filling punch 300. The first guide area 21 drives the guide component 13 to move upward. The guide component 13 drives the swing component 1 to rotate counterclockwise in direction a around the first axis, so that the swing component 1 gradually moves towards the pressing position and finally hooks the flanged part of the stamped part 5 downward. Then, as... Figure 6 As shown, the guide 13 cooperates with the second guide area 22. At this time, the guide 13 does not move in the vertical direction, the swing piece 1 remains in the pressing position, and the insert 301 can enter the flanged part of the stamped part 5 and fit against the flanged part of the stamped part 5. Then, as... Figure 7As shown, the guide 13 cooperates with the third guide area 23. The guide 13 moves downward and the swing piece 1 rotates clockwise in the direction b around the first axis. The swing piece 1 leaves the pressing position to avoid the swing piece 1 affecting the stamping process.

[0061] In some embodiments of the present invention, such as Figure 4 As shown, the sculpting mechanism 100 also includes an elastic element 3, which applies a rotational torque to the sculptor 1 in the direction of the guide member 13 near the guide surface 20.

[0062] Among them, the elastic element 3 has elastic force. When subjected to external force, the elastic potential energy of the elastic element 3 increases. In the direction of the guide element 13 near the guide surface 20, the elastic element 3 applies a rotational torque to the drive element 2.

[0063] In some embodiments of this application, the elastic element 3 can be constructed as a torsion spring. The torsion spring is elastic and will undergo elastic deformation when subjected to external force. The torsion spring is installed on the body part 11 and has two opposing ends. One end of the torsion spring is directly or indirectly fixedly connected to the stamping punch 200, and the other end of the torsion spring is fixedly connected to the swing element 1, such as... Figure 5 As shown, when the rocker 1 rotates around the first axis in a counterclockwise direction a, the torsion spring undergoes elastic deformation, and the elastic potential energy of the torsion spring increases. The torsion spring applies a clockwise torque to the drive member 2 in the opposite direction to the counterclockwise direction a. This torque allows the guide member 13 and the guide surface 20 to be more stably guided and matched, which is beneficial to enhancing the structural stability of the stamping die.

[0064] In some other embodiments of the present invention, the forming mechanism 100 further includes a counterweight (not shown in the figure), which can be mounted on the guide member 13. The counterweight applies a clockwise rotational torque b to the guide member 13 about the first axis. The counterweight can make the guide member 13 and the guide surface 20 more stably abut and cooperate, which is beneficial to enhancing the structural stability of the stamping die.

[0065] In some other embodiments of the present invention, the shaped mechanism 100 may be a crank-slider mechanism (not shown in the figure). The swing member 1 of the shaped mechanism 100 can realize the function of a crank, and the driving member 2 of the shaped mechanism 100 can realize the function of a slider. The driving member 2 and the swing member 1 are pivotally connected. When the filling punch 300 drives the driving member 2 to move, the driving member 2 can drive the swing member 1 to rotate so as to achieve the effect of the swing member 1 hooking down on the flipped part of the stamped part 5.

[0066] In some embodiments of the present invention, such as Figures 4-7 As shown, the styling mechanism 100 further includes a first adapter 41, which is adapted to be connected between the sway member 1 and the stamping punch 200, and is adapted to be detachably connected to at least one of the sway member 1 and the stamping punch 200.

[0067] The first adapter 41 can be fixedly connected to the stamping punch 200, and the first adapter 41 can be detachably connected to the pendant 1 so that the pendant 1 can be easily removed from the first adapter 41. Alternatively, the first adapter 41 can be fixedly connected to the pendant 1, and the first adapter 41 can be detachably connected to the stamping punch 200 so that both the first adapter 41 and the pendant 1 can be easily removed from the stamping punch 200. Alternatively, the first adapter 41 can be detachably connected to both the pendant 1 and the stamping punch 200 so that both the pendant 1 and the first adapter 41 can be easily removed from the stamping punch 200. This facilitates the repair or replacement of the pendant 1, reduces the difficulty of repair and replacement, and helps to reduce maintenance costs.

[0068] In some embodiments of the present invention, such as Figures 4-7 As shown, the pattern-forming mechanism 100 further includes a second adapter 42, which is adapted to be connected between the drive member 2 and the filling punch 300, and is adapted to be detachably connected to at least one of the drive member 2 and the filling punch 300.

[0069] The second adapter 42 can be fixedly connected to the filling punch 300, and can be detachably connected to the driving component 2 so that the driving component 2 can be easily disassembled from the second adapter 42. Alternatively, the second adapter 42 can be fixedly connected to the driving component 2, and can be detachably connected to the filling punch 300 so that both the second adapter 42 and the driving component 2 can be easily disassembled from the filling punch 300. Or, the second adapter 42 and the driving component 2, and the second adapter 42 and the filling punch 300 can both be detachably connected so that both the driving component 2 and the second adapter 42 can be easily disassembled from the filling punch 300. This facilitates the repair or replacement of the driving component 2, reduces the difficulty of repair and replacement, and helps to reduce maintenance costs.

[0070] In some embodiments of the present invention, such as Figures 4-7 As shown, the second adapter 42 includes a base 421 and at least one gasket 422. The drive member 2 is mounted on the base 421, and the gasket 422 is disposed between the base 421 and the filling punch 300.

[0071] The second adapter 42 includes a base 421, which is adapted to connect with the drive component 2. The drive component 2 can be installed on the base 421 by bolting or welding. The second adapter 42 includes a gasket 422, and there is at least one gasket 422. That is, the number of gaskets 422 can be, but is not limited to, one, two, three, etc. In some embodiments of the present invention, the specifications of the gaskets 422 can be the same. In other embodiments of the present invention, the specifications of the gaskets 422 can be different. The number and specifications of the gaskets 422 can be reasonably set according to the actual situation, as long as the drive component 2 and the guide component 13 can be stably and reliably abutted.

[0072] In the above embodiment, by mounting the drive component 2 on the base 421, the drive component 2 can be stably and reliably connected to the filling punch 300, which is beneficial to enhancing the stability of the stamping die. By setting a shim 422 between the base 421 and the filling punch 300, the height of the drive component 2 can be adjusted, which is beneficial to reducing the difficulty of debugging and maintaining the stamping die.

[0073] It should be noted that the conforming mechanism 100 of the present invention enables the stamping die structure to be compact, the movement stroke of the filling punch 300 to be short, and the structural length of the upper die mechanically driving the filling punch 300 to be short. This reduces the probability of interference between the robot arm transferring the stamped part 5 from the die and the die, allowing the robot arm to select a curve with a lower probability of interference for transferring the stamped part 5. Simultaneously, the robot arm's lifting stroke during the transfer of the stamped part 5 is short, thereby improving the production cycle time. The conforming mechanism 100 can be used for conforming the stamped part 5 in the previous process. Its swing member 1 can be formed with a roller lever structure, and the swing member 1 can press against the flange portion on one side of the stamped part 5.

[0074] According to another embodiment of the present invention, a stamping die includes: a stamping punch 200, a filling punch 300, and a forming mechanism 100 as described above, wherein the filling punch 300 is movable relative to the stamping punch 200.

[0075] According to the stamping die of the present invention, the filling punch 300 is adapted to drive the driving member 2 to drive the swing member 1 to rotate around the first axis to the pressing position, so that the swing member 1 drives the flanged portion of the stamped part 5 to be opposite to the filling punch 300 in the movement direction of the filling punch 300, thereby ensuring that the insert 301 on the filling punch 300 can accurately enter the flanged portion of the stamped part 5, so as to improve the yield of the stamped part 5.
