Description

Technical Field

[0001] This application relates to the field of mechanical manufacturing equipment technology, and in particular to a high-precision sheet metal straightening and leveling device. Background Technology

[0002] Traditional sheet metal straightening and leveling equipment has many shortcomings. Some equipment has limited leveling accuracy, making it difficult to meet the extremely high standards for sheet metal flatness required by high-end manufacturing industries. For example, in the aerospace field, if the sheet metal used to manufacture key components such as aircraft fuselages and wings does not meet the flatness standards, it will seriously affect the aerodynamic performance of the aircraft and increase flight risks. Some equipment has poor adjustment flexibility and cannot quickly and accurately adjust the position and parameters of key components such as cold rolling rolls for sheet metal of different thicknesses and materials, resulting in low production efficiency and an inability to adapt to diverse production needs.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing devices on the market mostly employ relatively simple transmission and adjustment methods, lacking a precise servo motor paired with a worm gear and bidirectional lead screw transmission system. When dealing with plates of different thicknesses and materials, existing devices struggle to accurately control the support position of the cold rolling rolls, resulting in a cumbersome and time-consuming adjustment process that cannot quickly respond to diverse production demands, severely hindering the improvement of production efficiency. Summary of the Invention

[0006] A cold rolling roll support mechanism includes a lower support mechanism and an upper support mechanism, which are arranged longitudinally symmetrically. Each support mechanism includes a positioning seat, a servo motor, a bearing seat, a rotating shaft, a worm gear, a worm wheel, a double-acting screw, a limiting shaft, and an internal threaded block.

[0007] Optionally, the cold rolling roll support mechanism further includes a first cold rolling roll support block, a second cold rolling roll support block, and a dynamic support assembly. The first cold rolling roll support block is fixedly installed on the top of the internal thread block. The first cold rolling roll support block and the second cold rolling roll support block are symmetrically arranged with the bidirectional lead screw as the center. The top of both the first cold rolling roll support block and the second cold rolling roll support block is provided with a dynamic support assembly.

[0008] Optionally, the drive mechanism includes a drive motor, a transmission gearbox, a bevel gearbox, and a base fixedly installed at the bottom of the drive motor, the transmission gearbox, and the bevel gearbox. The drive motor inside the drive mechanism drives multiple cold rolling rolls inside the lower cold rolling leveling mechanism to rotate through the transmission gearbox and the bevel gearbox. The multiple cold rolling rolls inside the lower cold rolling leveling mechanism are all movably connected to the top of the dynamic support assembly inside the lower support mechanism, and the multiple cold rolling rolls inside the upper cold rolling leveling mechanism are all movably connected to the bottom of the dynamic support assembly inside the upper support mechanism.

[0011] Optionally, the dynamic support assembly consists of a semi-circular base and multiple round shafts, wherein the semi-circular base is fixedly installed inside the semi-circular groove of the first cold rolling roll support block, and the multiple round shafts are movably installed on the top of the semi-circular base and are movably connected to the cold rolling roll.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. This utility model, through worm gear and worm wheel transmission and bidirectional lead screw transmission, can accurately transmit power and convert it into linear motion of the internal thread block, realizing precise adjustment of the support position of the cold rolling roll. This helps to improve the accuracy of sheet straightening and leveling. The lower support mechanism and upper support mechanism, composed of multiple sets of worms, worm wheels, bidirectional lead screws, limit shafts and internal thread blocks, together with the limit shaft's limiting effect on the internal thread block, can ensure the stability of the internal thread block during movement, thereby providing stable support for the cold rolling roll. This allows the cold rolling roll to maintain the correct position and posture when straightening and leveling the sheet, ensuring the consistency and stability of the leveling effect.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a high-precision sheet metal straightening and leveling device.

[0022] Please see Figure 1 A high-precision sheet metal straightening and leveling device includes a base plate 1, a driving mechanism 2 is provided on the top of the base plate 1, a lower cold rolling leveling mechanism 3 is provided on one side of the driving mechanism 2, an upper cold rolling leveling mechanism 4 is provided on the top of the lower cold rolling leveling mechanism 3, and a cold rolling roll support mechanism 5 is provided on one side of the upper cold rolling leveling mechanism 4.

[0023] Please see Figures 2 to 4 The cold rolling roll support mechanism 5 includes a lower support mechanism 51 and an upper support mechanism 52, which are arranged longitudinally symmetrically. Both the lower and upper support mechanisms include a positioning seat 501, a servo motor 502, a bearing seat 503, a rotating shaft 504, a worm gear 505, a worm wheel 506, a bidirectional lead screw 507, a limiting shaft 508, and an internal thread block 509. The positioning seat 501 is fixedly installed on the top of the base plate 1, and one side of the positioning seat 501 is fixed... A servo motor 502 is fixedly installed. A bearing housing 503 is fixedly installed on one side of the servo motor 502. A rotating shaft 504 is fixedly installed at the output end of the servo motor 502. A worm gear 505 is fixedly connected to one side of the rotating shaft 504. A worm wheel 506 is meshed and driven on one side of the worm gear 505. A bidirectional lead screw 507 is fixedly connected to one side of the worm wheel 506. Internal threaded blocks 509 are threaded on both sides of the bidirectional lead screw 507. Limiting shafts 508 are movably sleeved on both sides of the internal threaded blocks 509.

[0024] The cold rolling roll support mechanism 5 also includes a first cold rolling roll support block 510, a second cold rolling roll support block 511, and a dynamic support assembly 512. The first cold rolling roll support block 510 is fixedly installed on the top of the internal thread block 509. The first cold rolling roll support block 510 and the second cold rolling roll support block 511 are symmetrically arranged with the bidirectional lead screw 507 as the center. The top of both the first cold rolling roll support block 510 and the second cold rolling roll support block 511 is provided with a dynamic support assembly 512.

[0025] The drive mechanism 2 includes a drive motor, a transmission gearbox, a bevel gearbox, and a base fixedly installed at the bottom of the drive motor, the transmission gearbox, and the bevel gearbox. The drive motor inside the drive mechanism 2 drives multiple cold rolling rolls inside the lower cold rolling leveling mechanism 3 to rotate through the transmission gearbox and the bevel gearbox. The multiple cold rolling rolls inside the lower cold rolling leveling mechanism 3 are movably connected to the top of the dynamic support component 512 inside the lower support mechanism 51. The multiple cold rolling rolls inside the upper cold rolling leveling mechanism 4 are movably connected to the bottom of the dynamic support component 512 inside the upper support mechanism 52.

[0026] Both the lower support mechanism 51 and the upper support mechanism 52 are composed of multiple sets of worm gears 505, worm wheels 506, double-acting lead screws 507, limiting shafts 508 and internal thread blocks 509. The limiting shafts 508 are movably installed inside the groove of the positioning seat 501, and the rotating shafts 504 are movably installed on one side of the bearing seat 503.

[0027] The top of both the first cold rolling roll support block 510 and the second cold rolling roll support block 511 is provided with multiple semi-circular slots, and the multiple semi-circular slots correspond to the positions of the cold rolling rolls.

[0028] The dynamic support assembly 512 consists of a semi-circular base and multiple round shafts. The semi-circular base is fixedly installed inside the semi-circular groove of the first cold rolling roll support block 510, and the multiple round shafts are movably installed on the top of the semi-circular base and are movably connected to the cold rolling roll.

[0029] Further explanation is needed:

[0030] The servo motor 502 in the cold rolling roll support mechanism 5 provides power, which drives the worm 505 to rotate through the rotating shaft 504. The worm 505 meshes with the worm wheel 506 to transmit the rotational motion to the bidirectional lead screw 507, realizing the effective transmission and conversion of power, and providing a power basis for subsequent support adjustment actions.

[0031] Driven by the worm gear 506, the double-acting screw 507 rotates, causing the internal thread blocks 509, which are threaded on its left and right sides, to move linearly along the double-acting screw 507. The limiting shaft 508 limits the internal thread blocks 509, ensuring the accuracy of their movement. This allows for precise adjustment of the cold rolling roll support position, and the position of the cold rolling roll can be flexibly adjusted according to the different thicknesses and materials of the sheet metal.

[0032] The first cold rolling roll support block 510 and the second cold rolling roll support block 511 provide direct support for the cold rolling roll. The semi-circular groove at the top of the support block corresponds to the position of the cold rolling roll and can fit the cold rolling roll well. The multiple round shafts of the dynamic support component 512 are movably connected to the cold rolling roll, which can not only stably support the cold rolling roll, but also adapt to the rotation and slight displacement of the cold rolling roll during operation, ensuring that the cold rolling roll remains stable when straightening and leveling the sheet, thereby improving the leveling effect and accuracy.

[0033] The working principle of the above embodiments is as follows:

[0034] First, the drive motor in the drive mechanism 2 starts to work. The power of the drive motor is changed through the speed change gearbox to adjust to a suitable speed. Then, the power transmission direction is changed through the bevel gearbox to transmit the power to the lower cold rolling leveling mechanism 3.

[0035] Secondly, under the drive of the drive mechanism 2, the multiple cold rolling rollers inside the lower cold rolling leveling mechanism 3 begin to rotate. These cold rolling rollers come into contact with the sheet material placed on them. Using the friction and pressure generated by the rotation, the lower surface of the sheet material is initially straightened and leveled, so that the lower surface of the sheet material gradually becomes flat.

[0036] Next, the upper cold rolling leveling mechanism 4 is located above the lower cold rolling leveling mechanism 3 and works in coordination with the lower cold rolling leveling mechanism 3. The multiple cold rolling rollers inside the upper cold rolling leveling mechanism 4 also begin to rotate under the corresponding transmission action, and cooperate with the cold rolling rollers of the lower cold rolling leveling mechanism 3 to apply pressure and friction from both the upper and lower surfaces of the plate, further leveling the plate and improving its flatness under the squeezing and friction action of the upper and lower cold rolling rollers.

[0037] Next, the cold rolling roll support mechanism 5 comes into play. When it is necessary to adjust the position of the cold rolling roll to adapt to the leveling requirements of different plates, the servo motor 502 in the cold rolling roll support mechanism 5 is started. The servo motor 502 drives the worm gear 505 to rotate through the rotating shaft 504. The worm gear 505 meshes with the worm wheel 506, driving the bidirectional lead screw 507 to rotate. This causes the internal thread blocks 509 on both sides of the bidirectional lead screw 507 to move linearly along the bidirectional lead screw 507, thereby adjusting the position of the first cold rolling roll support block 510 and the second cold rolling roll support block 511, realizing precise support and position adjustment of the cold rolling roll, and ensuring the stability and accuracy of the cold rolling roll during operation.

[0038] Finally, through the coordinated work of the above-mentioned mechanisms, after the sheet metal undergoes multiple leveling processes by the lower cold rolling leveling mechanism 3 and the upper cold rolling leveling mechanism 4, as well as the precise support and adjustment of the cold rolling rolls by the cold rolling roll support mechanism 5, it finally achieves high-precision straightening and leveling, resulting in a sheet metal with flatness that meets the requirements.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
