Description

Technical Field

[0001] This application generally relates to the field of metal sheet processing and manufacturing, and specifically to a tooling for straightening irregularly shaped long plates. Background Technology

[0002] Currently, in the field of sheet metal processing and manufacturing, irregularly shaped long plates are widely used in high-end equipment industries such as aerospace, rail transportation, and shipbuilding. Due to their asymmetrical and complex cross-sectional structure (such as side plate designs containing right angles and included angles), deformation problems are easily generated during the production process. As a key step in ensuring the dimensional accuracy and geometric tolerances of irregularly shaped long plates, the straightening process directly affects the subsequent assembly quality and product performance. With the continuous improvement of the requirements for component precision and production efficiency in the high-end equipment manufacturing industry, the straightening process has become an indispensable and important step in the production process of irregularly shaped long plates.

[0003] However, the unique structural characteristics of irregularly shaped long plates present significant challenges to the straightening process. On the one hand, the presence of right angles and included angles on the irregularly shaped long plates leads to uneven stress distribution and unstable center of gravity. If placed directly on the pressing platform, local over-straightening or under-straightening is likely to occur. On the other hand, traditional straightening equipment often uses symmetrical support and force application structures, which cannot effectively fix and specifically straighten the irregularly shaped parts of the long plates, resulting in low straightening efficiency and severely restricting production progress and economic benefits. Therefore, this application provides a straightening fixture for irregularly shaped long plates that can meet the straightening requirements of complex structures while also considering ease of operation and stability.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the portions of the invention shown in the drawings are relevant.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] This application provides a straightening fixture for irregularly shaped long plates, including: Multiple support bases 1 are detachably mounted on the press-fitting platform and are distributed sequentially along the extension direction of the irregular long plate for mounting the irregular long plate. A set of clamping plates 2 is provided on each support base 1. The clamping plates 2 are located on the side of the support base 1 close to the irregular long plate, and each set of clamping plates 2 is symmetrically arranged on both sides of the irregular long plate. The relative position of the clamping plates 2 and the support base 1 is adjustable and used to clamp the irregular long plate.

[0024] It should be noted that the support base 1 can be flexibly adjusted in installation position and quantity according to the specific conditions such as the length and shape of the irregular long plate, and can be detachably installed on the pressing platform, thus providing stable support for the irregular long plate; the clamping plates 2 are symmetrically arranged on both sides of the irregular long plate and are slidably connected to the support base 1. The symmetrical arrangement of the clamping plates 2 can clamp the irregular long plate, and the position of the clamping plates 2 can be adjusted according to different specifications of irregular long plates to prevent displacement of the irregular long plate during straightening and ensure stability during the straightening process. It is understandable that, as Figure 1 and Figure 2 As shown, the clamping plate 2 and the support base 1 are detachably connected by bolts and nuts. Before clamping, the nuts can be loosened. According to the specifications of the irregular long plate to be clamped, the clamping plate 2 is moved to the clamping position so that the clamping plate 2 abuts against the irregular long plate. The nuts are then tightened to install the clamping plate 2 in this position, thereby clamping the irregular long plate. Additionally, as... Figure 2 and Figure 3 As shown, by setting an adjustment mechanism 3 inside the support base 1, the movement of the pressure plate 2 can be controlled and adjusted to ensure that the position of the pressure plate 2 can be flexibly adjusted according to the specifications of the irregular long plate. When straightening the irregular long plate, the pressure plate 2 can be driven to move until it is in contact with and clamps the irregular long plate through the adjustment mechanism 3, thereby achieving the clamping limit of the irregular long plate.

[0025] Furthermore, the device also includes an adjustment mechanism 3, which is located inside the support base 1 and is used to drive the pressure plate 2 to move on the support base 1. The adjustment mechanism 3 and the pressure plate 2 are detachably connected.

[0026] It should be noted that the adjustment mechanism 3 is built into the support base 1 and forms a detachable connection with the clamping plate 2. On the one hand, according to the different specifications of the irregular long plates, the clamping plate 2 can be moved by the adjustment mechanism 3, which improves the convenience of the overall operation of the tooling when straightening the irregular long plates; on the other hand, it is convenient to replace the adjustment mechanism 3 or the clamping plate 2 separately when they are damaged.

[0027] Furthermore, the clamping plate 2 is L-shaped, including a longitudinal plate 5 and a transverse plate 4. The transverse plate 4 is used to contact the support base 1, and a through hole 6 is provided on the transverse plate 4.

[0028] It should be noted that the clamping plate 2 is designed in an L-shape. Its longitudinal plate 5 is mainly used to contact the side of the irregular long plate. The longitudinal plate 5 forms a stable lateral clamping force on the irregular long plate, ensuring that the irregular long plate does not tilt or shift during the pressing and straightening process. The transverse plate 4 contacts the support base 1, which provides installation support for the entire clamping plate 2 on the one hand, and on the other hand, the transverse plate 4 is provided with through holes 6 to realize the fixing of the connecting mechanism 9 and the clamping plate 2.

[0029] Furthermore, the side of the support base 1 that contacts the clamping plate 2 is provided with two elongated holes 7, which are symmetrically arranged on both sides of the irregularly shaped long plate.

[0030] It should be noted that the elongated hole 7 provides a structural basis for the sliding connection between the pressing plate 2 and the support base 1. Its length direction is consistent with the moving direction of the pressing plate 2. When the pressing plate 2 slides along the support base 1 under the drive of the adjusting mechanism 3, the elongated hole 7 can accommodate the connecting mechanism 9 to move synchronously with the pressing plate 2, ensuring that the pressing plate 2 can be adjusted to adapt to irregularly shaped long plates of different specifications. At the same time, the two elongated holes 7 are symmetrically distributed on both sides of the irregularly shaped long plate, matching the symmetrical layout of the pressing plate 2, preventing the offset problem caused by the limitation of the unilateral structure.

[0031] Furthermore, the adjustment mechanism 3 includes a drive mechanism 8 and a connecting mechanism 9. The drive mechanism 8 and the connecting mechanism 9 are connected by transmission, and the connecting mechanism 9 is detachably connected to the pressure plate 2.

[0032] It should be noted that the drive mechanism 8 provides driving force and transmits power to the connecting mechanism 9 through a transmission connection, thereby driving the clamping plate 2 to adjust its position and ensuring that the clamping plate 2 can clamp or release the irregular long plate; the connecting mechanism 9 achieves flexible assembly and separation of the clamping plate 2 and the adjusting mechanism 3 through a detachable connection with the clamping plate 2.

[0033] Furthermore, the connecting mechanism 9 includes two sets of nuts 10, bolts 11 and threaded sliders 12 symmetrically arranged on both sides of the irregular long plate. One end of the bolt 11 passes through the through hole 6 and the elongated hole 7, and is fixed to the pressure plate 2 by the nuts 10 symmetrically arranged on both sides of the transverse plate 4. The other end is fixedly connected to the threaded slider 12, which is connected to the drive mechanism 8 for transmission.

[0034] It should be noted that after the bolt 11 passes through the through hole 6 and the elongated hole 7, it is fastened to the clamping plate 2 by the nuts 10 on both sides of the transverse plate 4, preventing the clamping plate 2 from loosening relative to the bolt 11 during the stress process. The size of the nut 10 and the diameter of the bolt 11 on the side of the transverse plate 4 that contacts the elongated hole 7 are limited by the width of the elongated hole 7. When the connecting mechanism 9 drives the clamping plate 2 to move, the elongated hole 7 provides a guiding function, restricting the clamping plate 2 to move only along the length direction of the elongated hole 7. At the same time, the other end of the bolt 11 is fixedly connected to the threaded slider 12, and the threaded slider 12 is connected to the drive mechanism 8 for transmission, so that the power provided by the drive mechanism 8 can be transmitted to the clamping plate 2 in sequence through the threaded slider 12 and the bolt 11, realizing the movement of the clamping plate 2.

[0035] Furthermore, the drive mechanism 8 includes two sets of threaded rods 13 and handwheels 14 symmetrically arranged on both sides of the support base 1. One end of the threaded rod 13 is fixedly connected to the handwheel 14, and the other end passes through the threaded slider 12 and is threadedly connected to the threaded slider 12. The thread direction on the surface of the threaded rod 13 is the same. Both ends of the threaded rod 13 are rotatably connected to the support base 1.

[0036] It should be noted that the handwheel 14, as an operating component, is fixedly connected to one end of the threaded rod 13. By rotating it, a force is applied to the threaded rod 13, thereby driving the threaded rod 13 to rotate. The threaded rod 13 is threadedly connected to the threaded slider 12, which can convert the rotational motion of the threaded rod 13 into the linear motion of the threaded slider 12, thereby driving the connecting mechanism 9 and the pressure plate 2 to move, realizing the position adjustment of the pressure plate 2. The threads on the surfaces of the threaded rods 13 on both sides have the same thread direction and correspond to the threaded sliders 12 on both sides of the support base 1, ensuring that when the handwheel 14 is rotated synchronously, the connecting mechanism 9 can drive the pressure plate 2 to move, clamping or loosening the irregular long plate. At the same time, the support base 1 is provided with a bearing 15 at the position corresponding to the threaded rod 13. The threaded rod 13 passes through the bearing 15 and is fixedly connected to the inner ring of the bearing 15. The bearing 15 provides stable support for the threaded rod 13 and prevents the threaded rod 13 from lateral displacement during rotation.

[0037] Furthermore, the drive mechanism 8 includes a threaded rod 13 with both ends passing through two threaded sliders 12 and extending to the outside of the support base 1, and being rotatably connected to the support base 1. The thread direction of the threaded rod 13 and the two threaded sliders 12 are opposite, and handwheels 14 are provided at both ends of the threaded rod 13.

[0038] It should be noted that, as Figure 4 As shown, the threaded rod 13 can also be an integrated design. In this case, the threads at both ends of the threaded rod 13 turn in opposite directions, so that when the rotating handwheel 14 drives the threaded rod 13 to rotate, the threaded sliders 12 on both sides will move synchronously in opposite directions along the threaded rod 13, thereby driving the clamping plate 2 to clamp or loosen the irregular long plate synchronously. When the threaded rod 13 is an integrated design, only a single handwheel 14 needs to be operated to synchronously control the movement of the clamping plates 2 on both sides, which simplifies the operation process and ensures that the clamping force on both sides of the irregular long plate is always balanced, avoiding uneven force caused by unilateral adjustment, thereby preventing the irregular long plate from shifting during the straightening process.

[0039] Furthermore, a sliding base 16 is provided on the side of the support base 1 near the pressing platform. The sliding base 16 is fixedly connected to the support base 1 and is used to engage and slide with the groove on the pressing platform.

[0040] It should be noted that the size of the sliding base 16 matches the size of the groove on the pressing platform, which enables the support base 1 to slide smoothly along the groove and avoid deviation, thereby quickly finding the appropriate support position. At the same time, the sliding base 16 can limit the support base 1, preventing the support base 1 from shaking when bearing the straightening force of the irregular long plate, thus enhancing the support stability.

[0041] Working principle: The support base 1 is installed on the pressing platform. The installation position and number of support base 1 on the pressing platform can be adjusted according to the specific conditions such as the length and shape of the irregular long plate. The irregular long plate is placed in the middle of the clamping plate 2. The adjusting mechanism 3 drives the clamping plate 2 to move closer to each other and stick tightly to the irregular long plate, forming a symmetrical clamping force to prevent the irregular long plate from shifting during the straightening process. When the external mechanism applies pressure to the part to be straightened, the support base 1 provides a reaction force for support. The clamping plate 2 ensures that the irregular long plate does not tilt or shift during the straightening process. After straightening is completed, the adjusting mechanism... The clamping plate 2 is released by the drive mechanism 3, and the irregular long plate is removed, completing the straightening process. The irregular long plate straightening fixture designed in this application forms multi-point stable support for the irregular long plate by setting multiple adjustable support bases 1, which effectively solves the problem of unstable center of gravity and easy displacement of the irregular long plate. The symmetrically distributed clamping plates 2 can be clamped according to the position of the irregular long plate with different thicknesses under the drive of the adjustment mechanism 3, avoiding displacement of the irregular long plate under the action of external force, improving the straightening efficiency, meeting the straightening requirements of complex irregular long plate structures, and taking into account the convenience and stability of operation.
