[0002] Vehicle sheet metal parts generally refer to various thin metal sheets used in cars or other vehicles. They play an important role in vehicle manufacturing and maintenance, and are usually used in parts such as body, chassis, sound insulation, and structural support. Common metal materials include steel, aluminum, and stainless steel. Sheet metal parts not only provide the external structure and aesthetics of the vehicle, but also enhance safety, improve rigidity, and reduce weight.

[0003] The production of metal sheet parts usually involves stamping, welding, bending and other processes. Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size.

[0004] The Chinese patent document with reference announcement number CN219274301U discloses a side panel stamping tool, including a shell, an operating table fixedly connected to the top of the shell, an auxiliary mechanism fixedly connected to the top of the operating table, a lower die seat fixedly connected to the top of the operating table, a demoulding mechanism arranged inside the lower die seat, the demoulding mechanism including a stamping groove, the stamping groove is arranged at the top of the lower die seat, and a receiving groove is arranged at the bottom of the stamping groove. The technical solution of this patent is that after the stamping is completed, the side panel of the car seat can be demoulded by the demoulding mechanism.

[0005] Regarding the above-mentioned related technologies, after the stamping of the side panel of the automobile seat is completed, this patent can use the demolding mechanism to push the formed parts in the stamping groove out from the bottom and complete the demolding of the side panel of the automobile seat. However, when stamping side panels of different specifications, it may be detrimental to the stamping work, and the workpiece after demolding is not convenient for the staff to take out. Summary of the invention

[0006] In view of this, the present invention provides a vehicle metal sheet stamping tool, aiming to solve the problem in the prior art that it is difficult to adapt to workpieces of different sizes and it is inconvenient to take out the stamped workpieces.

[0007] In order to solve the above technical problems, the present invention provides a vehicle metal sheet stamping tool, comprising two workbenches, a double-acting cylinder is arranged between the two workbenches, one side of the workbenches is connected to the driving shaft of the double-acting cylinder, a first linear actuator is slidably installed on both sides of each workbench, a second linear actuator is fixedly installed in the middle of each workbench, a driving shaft of the first linear actuator is fixedly connected to a first supporting platform, a driving shaft of the second linear actuator is connected to a second supporting platform, a first supporting plate is arranged on the first supporting platform, and a second supporting plate is arranged on the second supporting platform; The workbench is provided with an adaptation mechanism capable of rotating the first support plate or the second support plate, the adaptation mechanism includes a first connecting rod and a second connecting rod, the first connecting rod is hinged to the first linear drive or the second linear drive, the second connecting rod is hinged to the top of the first connecting rod, and the second connecting rod is fixedly connected to the bottom of the first support plate or the second support plate.

[0008] By adopting the above technical scheme, under the action of the double-acting cylinder, the two workbenches can be moved closer to or away from each other to facilitate the placement of the mold, and can adapt to molds of different sizes, thereby improving the adaptability of the tooling. The first support platform can slide relative to the workbench, and the position of the first support platform can be adjusted by sliding the first support platform, thereby adapting to the position of the mold and the workpiece, thereby facilitating the stamping work and adapting to molds of different sizes. When stamping the metal sheet, the first linear drive and the second linear drive are started to drive the first support platform and the second support platform to descend, so that the first support plate and the second support plate rotate and tilt, thereby dispersing the load applied to the edge and distributing the stress to a larger area. At the same time, the inclined first support plate and the second support plate provide additional support, which can enhance the strength of the edge and reduce the stress concentration caused by deformation. After the stamping work is completed, the metal sheet can be demolded by the setting of the first linear drive and the second linear drive, and moving the first support platform can facilitate the removal of the stamped sheet, thereby improving work efficiency.

[0009] Optionally, one of the first support platforms is fixedly connected to first connecting plates on both sides, and another first support platform is fixedly connected to second connecting plates on both sides, and the first connecting plates are slidably connected to the second connecting plates.

[0013] Optionally, a translation mechanism capable of moving out the stamped plate is provided in the middle of each workbench.

[0014] By adopting the above technical solution, when the stamping is completed, the movable platform can be moved in the horizontal direction through the setting of the translation mechanism, thereby driving the plate after the stamping to be translated, thereby reducing the interference of the mold or the press, facilitating the subsequent removal by the staff and reducing the labor intensity of the staff.

[0016] By adopting the above technical solution, when it is necessary to facilitate the removal of the stamped plate, the movable platform can be moved in the horizontal direction through the transmission of the first gear, the second gear and the rack, so that it can cooperate with the first support platform to move the demolded plate out, thereby reducing the interference of the mold or press on the plate, making it easier for the staff to remove the plate.

[0017] Optionally, a ratchet is fixedly connected to one side of the first gear, a pawl cooperating with the ratchet is hinged to the side of the first gear close to the ratchet, and a reset torsion spring is provided in the pawl.

[0022] By adopting the above technical solution, the second support plate is longer and can provide stable support for the plate, thereby improving the stability of the support for the plate when the first support platform moves.

[0023] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1. The distance between the two workbenches can be adjusted by setting a double-acting cylinder, and the distance between the two first support platforms can be adjusted by moving the first support platforms on both sides.

Figure 1-Figure 4, the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0029] Reference Figure 1 and Figure 2 A vehicle metal sheet stamping tool includes two workbenches 1, a double-acting cylinder 11 arranged between the two workbenches 1, a first linear drive 12 and a second linear drive 13 installed on the workbenches 1, a first support platform 14 and a second support platform 15 for supporting the sheet, a first support plate 16 and a second support plate 17 for supporting the edge of the sheet, and an adaptation mechanism 2 capable of rotating the first support plate 16 or the second support plate 17.

[0030] Reference Figure 2 , two workbenches 1 are symmetrically arranged about the double-acting cylinder 11; each output shaft of the double-acting cylinder 11 is connected to a workbench 1 respectively. In this embodiment, the double-acting cylinder 11 is a double-output rod type double-linked cylinder. In other embodiments, suitable equipment can be selected according to actual needs. The double-output rod type double-linked cylinder is a cylinder with two output rods, which is used to realize two-way pushing or pulling force transmission. It consists of two cylinders, each cylinder has an output rod, and the two output rods can push or pull operations simultaneously or separately. The double output rod design of this cylinder can provide greater thrust or pulling force, and can realize more complex motion control. It is often used in applications that require simultaneous pushing and pulling, such as robotic arms, clamps, etc. The double output rod type double-linked cylinder has the advantages of simple structure, easy installation and flexible operation.

[0031] Reference Figure 1 and Figure 2The second linear actuator 13 is fixedly installed in the middle of the workbench 1, and the first linear actuator 12 is slidably installed on both sides of the workbench 1. The workbench 1 is provided with a slide groove 6 for the first linear actuator 12 to slide. In this embodiment, the first linear actuator 12 and the second linear actuator 13 on each workbench 1 are set to two. In other embodiments, the number of the first linear actuator 12 and the second linear actuator 13 can be selected according to actual needs. The first support platform 14 is connected to the driving shaft of the first linear actuator 12, and the second support platform 15 is connected to the driving shaft of the second linear actuator 13. Both sides of one of the first support platforms 14 on each workbench 1 are fixedly connected with a transversely extending first connecting plate 3, and both sides of the other first support platform 14 are fixedly connected with a transversely extending second connecting plate 31. A sliding block 32 is fixedly connected to the first connecting plate 3, and a sliding groove 33 for the sliding block 32 to slide is provided on the second connecting plate 31. Under the action of the first connecting plate 3 and the second connecting plate 31, the staff can adjust the distance between the two first supporting platforms 14 by pushing the first supporting platform 14, so as to adapt to the size of the mold 7 and adjust the position of the plate at the same time to facilitate the stamping work.

[0032] Reference Figure 2 and Figure 3 The second support platform 15 includes a connecting platform 151 and a moving platform 152. The connecting platform 151 is fixedly connected to the driving shaft of the second linear actuator 13. The moving platform 152 is laterally slidably connected to the top of the connecting platform 151. The first support plate 16 is arranged above the first support platform 14. The second support plate 17 is arranged above the second support platform 15. The length of the second support plate 17 is greater than that of the first support plate 16, so that the second support plate 17 can support the plate when the first support plate 16 moves.

[0033] Reference Figure 1 and Figure 4The adapting mechanism 2 is arranged at the first support platform 14 and the second support platform 15. The adapting mechanism 2 includes a first connecting rod 21 and a second connecting rod 22. The first connecting rod 21 is hinged to the first linear actuator 12 or the second linear actuator 13. The second connecting rod 22 is hinged to the top of the first connecting rod 21, and the second connecting rod 22 is fixedly connected to the bottom of the first support plate 16 or the second support plate 17. When the plate is stamped, the first linear actuator 12 and the second linear actuator 13 are started to drive the first support platform 14 and the second support platform 15 to move downward. Under the action of the first connecting rod 21 and the second connecting rod 22, the first support plate 16 and the second support plate 17 form an inclination angle with the first support platform 14 and the second support platform 15, so that the load applied to the edge can be dispersed and the stress can be distributed to a larger area. At the same time, the inclined first support plate 16 and the second support plate 17 provide additional support, which can enhance the strength of the edge and reduce the stress concentration caused by deformation.

[0034] Reference Figure 3 Each workbench 1 is provided with a translation mechanism 4 in the middle thereof, which can move the stamped plate out (refer to Figure 1 ). The translation mechanism 4 includes a support shell 41, a first gear 42, a second gear 43 and a rack 44. The support shell 41 is fixedly connected to the middle of the workbench 1 and is located below the second support platform 15. The first gear 42 is rotatably connected to the support shell 41 and is vertically arranged. The second gear 43 is rotatably connected to the support shell 41 and meshes above the first gear 42. The rack 44 is fixedly connected to the bottom of the moving platform 152 and extends horizontally. The rack 44 meshes with the second gear 43. By setting a driving motor, the first gear 42 can be driven to rotate. The rotation of the first gear 42 drives the rotation of the second gear 43. The rotation of the second gear 43 drives the rack 44 to move. As the rack 44 moves, the rack 44 drives the moving platform 152 to move in the horizontal direction, so as to move the plate out. A ratchet 5 is fixedly connected to one side of the first gear 42, and a pawl 51 cooperating with the ratchet 5 is hinged on the side of the first gear 42 close to the ratchet 5. A reset torsion spring 52 is provided in the pawl 51. The ratchet 5 and the pawl 51 cooperate with each other to prevent the first gear 42 from rotating in the opposite direction, thereby ensuring that the movement of the moving platform 152 is irreversible and improving the stability and reliability of the device.

[0035] The implementation principle of a stamping tool for a metal sheet of a vehicle according to an embodiment of the present invention is as follows: before stamping the sheet, firstly, the adjustment is made according to the size of the mold 7, and the two workbenches 1 can be driven to move closer to or away from each other by the double-acting cylinder 11 to adapt to the size of the mold 7, and then the distance between the two first support platforms 14 is adjusted by pushing and pulling the first support platform 14 to adapt to the size of the mold 7 and the sheet. When stamping the sheet, the first linear drive 12 and the second linear drive 13 are started to drive the first support platform 14 and the second support platform 15 to move downward, so that the first support plate 16 and the second support plate 15 are aligned with each other. The two support plates 17 rotate and tilt, thereby reducing the occurrence of stress concentration at the edges of the panels when stamping the panels. After the stamping of the panels is completed, the first linear drive 12 and the second linear drive 13 are started to drive the first support platform 14 and the second support platform 15 to move upward, which is beneficial to the demolding of the panels. Then the first gear 42 is rotated, the first gear 42 drives the second gear 43 to rotate, the second gear 43 drives the rack 44 to move, the rack 44 moves and drives the moving platform 152 to move. The movement of the moving platform 152 can drive the stamped panels to move, so as to facilitate the removal of the stamped panels.
