Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a rust removal device for metal surface treatment. Background Technology

[0002] Metals are substances that possess luster, ductility, and good electrical and thermal conductivity. The vast majority of metallic elements on Earth exist in nature in a combined state. This is because most metals are chemically reactive, with only a very few, such as gold and silver, existing in a free state. Metals are widely found in nature and are extremely common in daily life. They are a very important and widely used class of substances in modern industry. Currently, in order to conserve resources and improve resource utilization, it is necessary to remove rust from used metal plates. Chinese utility model patent, authorization announcement number "CN211103308U", discloses a metal rust removal device, including a fixed plate and four support legs. Support legs are fixedly installed at the four corners of the bottom of the fixed plate, and a limiting groove for fixing the metal plate is opened at one corner of the bottom of the fixed plate. Mounting plates are fixedly installed on one side and one side of the top of the fixed plate, directly opposite the limiting groove.

[0003] The above technical solution can grind and remove rust from every part of the upper surface of the metal plate through the grinding component. However, the above technical solution still has certain defects. Since the size of the limiting groove is fixed, when encountering a metal plate larger than the size of the limiting groove, the metal plate will be unstable when limiting the metal plate and will easily shift during the grinding and rust removal process, affecting the grinding and rust removal effect. Therefore, this utility model proposes a new solution. Utility Model Content

[0026] Please see Figure 1-4This utility model provides a technical solution: a rust removal device for metal surface treatment, including a base 1, a fixed frame 2 fixedly connected to the upper end of the base 1, a metal plate fixing assembly, the metal plate fixing assembly being disposed on the fixed frame 2, the metal plate fixing assembly including two fixing brackets 9, both fixing brackets 9 being fixedly connected to the fixed frame 2, fixing rings 10 fixedly connected to the opposite faces of the two fixing brackets 9, a turntable 11 rotatably connected to the inner side of the fixing rings 10, a plurality of weight reduction grooves being formed on the surface of the turntable 11, a second sliding groove 15 being formed on the surface of the turntable 11, a second hydraulic rod 16 being fixedly connected inside the second sliding groove 15, a metal plate limiting plate 17 being fixedly connected to the output end of the second hydraulic rod 16, and the metal plate limiting plate 17 being slidably connected to the second sliding groove 15.

[0027] The metal plate fixing assembly also includes a toothed ring 12, which is fixedly connected to the outer surface of the turntable 11. The toothed ring 12 is rotatably connected to the fixed ring 10. The lower end of the fixed ring 10 is fixedly connected to a second drive motor 13. The output end of the second drive motor 13 extends into the interior of the fixed ring 10 and is fixedly connected to a gear 14, which meshes with the toothed ring 12.

[0028] The number of the second slide 15, the second hydraulic rod 16, and the metal plate limiting plate 17 are all four sets arranged in a circular array on the turntable 11.

[0029] A third hydraulic rod 18 is fixedly connected to the upper end of the base 1, and a metal plate support plate 19 is fixedly connected to the output end of the third hydraulic rod 18. A through groove is provided on the surface of the turntable 11 to accommodate the metal plate support plate 19.

[0030] The right end of the fixed frame 2 is fixedly connected to the first drive motor 3, and the output end of the first drive motor 3 is fixedly connected to the threaded rod 5. The threaded rod 5 is rotatably connected to the fixed frame 2, and the surface of the threaded rod 5 is threaded with a movable block 6.

[0031] The upper end of the fixed frame 2 is provided with a first sliding groove 4, the movable block 6 is slidably connected to the first sliding groove 4, the lower end of the movable block 6 is fixedly connected to a first hydraulic rod 7, and the output end of the first hydraulic rod 7 is fixedly connected to a laser emitter 8.

[0032] When using this device, activate the third hydraulic rod 18 to raise the metal plate support plate 19 at its output end to the through groove on the surface of the turntable 11, forming a horizontal support platform; place the metal plate to be derusted on the metal plate support plate 19, ensuring that the plate surface is in contact with the metal plate support plate 19, and place the metal plate onto the surface of the turntable 11 through the metal plate support plate 19; control the four sets of annular array of second hydraulic rods 16 to extend synchronously, pushing the metal plate limiting plate 17 to move radially along the second slide groove 15 until the four sets of limiting plates are evenly pressed against the edge of the metal plate (e.g., Figure 4(As shown); the synchronous extension and retraction of the second hydraulic rod 16 is controlled by the hydraulic system, which can adapt to metal plates of different sizes (such as rectangular and circular), thus solving the limitations of fixed-size limiting grooves in the prior art.

[0033] The second drive motor 13 is started, and through the meshing transmission of gear 14 and gear ring 12, it drives the turntable 11 and the metal plate fixed on it to rotate; the weight-reducing grooves on the surface of the turntable 11 reduce rotational inertia and improve rotational flexibility; the ring array limiting structure ensures that the metal plate is subjected to uniform force during rotation and avoids deviation (such as...). Figure 3 (As shown).

[0034] The first drive motor 3 drives the threaded rod 5 to rotate, causing the movable block 6 to move up and down along the first slide groove 4, adjusting the height of the first hydraulic rod 7 and the laser emitter 8 so that they are aligned with the area of ​​the metal plate to be derusted; the threaded rod 5 adjusts the laser head to the upper part of the plate surface; and moves it to a suitable position, cooperating with the rotation of the turntable 11 to achieve full-size coverage.

[0035] The first hydraulic rod 7 is activated, pushing the laser emitter 8 towards the surface of the metal plate until the preset focusing distance is reached. The laser emitter 8 emits a high-energy laser beam, utilizing the thermal effect or photo-abrasion effect of the laser (such as the instantaneous vaporization of rust by a pulsed laser) to remove rust, oxide layers, and other impurities from the surface of the metal plate. The metal plate continues to rotate with the turntable 11, and the laser beam performs a circumferential scan of the rotating plate surface at a fixed position, achieving large-area uniform rust removal (such as...). Figure 1 , 2 (As shown).

[0036] The four sets of second hydraulic rods 16 and the metal plate limiting plate 17 are arranged in a 90° ring (which can provide symmetrical clamping force for regular-shaped metal plates such as squares and circles, avoiding the defect that traditional limiting grooves can only fix workpieces of a single size; the transmission ratio design of the toothed ring 12 and the gear 14 ensures that the turntable 11 rotates smoothly, and with the position locking of the laser head, the rust removal trajectory can be precisely controlled.

[0037] The threaded rod 5 and the first slide groove 4 enable the horizontal feeding of the laser head, the first hydraulic rod 7 enables vertical lifting, and the turntable rotation provides circumferential motion.

[0038] When not in operation, the metal plate support plate 19 is stored at the lower end of the through groove of the turntable 11 to avoid interfering with the rotation of the turntable; when in operation, it rises to form a support surface to ensure that the metal plate is placed stably. After rust removal is completed, the metal plate support plate 19 rises to detach the metal plate from the turntable 11, making it easy to remove the metal plate from the device 1.

[0039] Furthermore, the four sets of second hydraulic rods 16 and the metal plate limiting plate 17 are arranged in a ring array and can be synchronously extended and retracted by the hydraulic system, which can accurately adapt to rectangular or circular metal plates of different sizes. Compared with the limiting groove of fixed size, there is no need to manually change the clamps or adjust the structure, which solves the problem of "the fixed size of the limiting groove causes large-sized plates to be unable to be stably clamped", and is especially suitable for the rapid processing of multi-specification plates in the scrap metal recycling scenario.

[0040] The metal plate support plate 19 achieves lifting linkage through the third hydraulic rod 18: when working, it rises to support the plate, making it easy for the limiting plate to clamp the edge from below; after rust removal, it rises again to detach the plate from the turntable 11, eliminating the need for manual flipping or prying and reducing labor intensity; the through slot design of the turntable 11 ensures that the metal plate support plate 19 is completely stored when not in operation, avoiding interference with rotational movement, and has a compact structure and occupies little space.

[0045] Fixed ring 10: The inner side is rotatably connected to the turntable 11, and the outer side is engaged with the gear ring 12 through the gear 14 to transmit the rotational power of the second drive motor 13;

[0046] Turntable 11: It carries the metal plate and drives it to rotate, realizing circumferential scanning for laser rust removal;

[0047] The weight-reducing groove reduces its own weight and rotational inertia, improving rotational flexibility; the second slide 15 provides a radial movement track for the metal plate limiting plate 17;

[0048] The through slot accommodates the metal plate support plate 19, preventing it from interfering with the rotation of the turntable;

[0049] Second hydraulic rod 16: Driven by the hydraulic system, it pushes the limiting plate 17 to extend and retract radially along the second slide groove 15, so as to realize adaptive clamping of metal plates of different sizes (four sets of ring arrays are distributed and symmetrically abut against the edge of the plate).

[0050] Metal plate limiting plate 17: directly contacts the edge of the metal plate, provides clamping force, and ensures that the plate is stable and does not shift during rotation;

[0051] Gear ring 12: Fixed to the outside of turntable 11, meshing with gear 14, transmitting the power of the second drive motor 13 to the turntable, driving it to rotate;

[0052] Second drive motor 13: provides the power source for the rotation of the turntable, and achieves smooth rotation through gear transmission;

[0053] Gear 14: meshes with gear ring 12, adjusts the transmission ratio to control the turntable speed, and ensures a uniform and stable rust removal process;

[0054] The third hydraulic rod 18 drives the metal plate support plate 19 to rise and fall. When working, it rises to form a horizontal support platform, which is convenient for placing the metal plate. After the rust removal is completed, it rises again to remove the plate from the turntable, which is convenient for unloading.

[0055] Metal plate support plate 19: Supports the metal plate to be derusted, ensuring the plate surface is flat and fits snugly; when not in use, it is stored in the turntable slot to avoid interference with rotation;

[0056] First drive motor 3: drives threaded rod 5 to rotate, drives movable block 6 to move along first slide groove 4, adjusts the horizontal feed (Y-axis adjustment) of laser emitter 8, and adapts to the rust removal area of ​​metal plates of different sizes;

[0057] Threaded rod 5: Converts the rotational motion of the motor into the linear motion of the movable block 6 through threaded transmission, thereby achieving precise adjustment of the laser head height;

[0058] First hydraulic rod 7: pushes the laser emitter 8 vertically (Z-axis adjustment) to control the focusing distance between the laser beam and the metal plate surface, ensuring precise output of rust removal energy;

[0059] Laser emitter 8: Emits a high-energy laser beam to remove rust and oxide layers from the surface of metal plates using thermal or optical stripping effects. It supports the replacement of different power modules to adapt to various rust removal needs.
