Description

Technical Field

[0001] This utility model relates to the field of leveling equipment technology, and in particular to an automatic leveling equipment for metal sheets on a production line. Background Technology

[0002] Metal sheets are standardized flat rectangular materials made from metal as the base material through plastic processing processes such as rolling, extrusion, and forging. Automatic metal sheet leveling refers to an automated process that uses CNC equipment (such as multi-roller leveling machines) to apply precise mechanical force to metal sheets, eliminating internal stress and deformation defects, and achieving high-precision flatness. Its core function is to provide a flat base material for subsequent processing.

[0003] Traditional leveling equipment uses a multi-roller staggered arrangement structure, relying on the pressure between the upper and lower roller groups to repeatedly bend and plastically deform the sheet metal to eliminate stress. The roller gap relies on mechanical and hydraulic synchronous adjustment, which is difficult to adapt to local deformation and cannot be adjusted in time according to the strength of the sheet metal. Hard contact can easily scratch the surface, and thin plates are easily crushed, resulting in over-straightening and reducing the overall straightening quality of the metal sheet metal. Utility Model Content

[0005] The technical solution is as follows: An automatic leveling equipment for metal sheets in a production line includes a base, on which several sets of parallel rollers are linearly arranged to form a reference surface for automatic leveling of the metal sheets. Above the base, several sets of leveling adjustment components are provided for pressure control and leveling adjustment of the corresponding parallel rollers. A pressure box for pressure control is provided outside the leveling adjustment components.

[0006] Furthermore, brackets are fixed to the four corners of the base, shock-absorbing pads are fixed to the top of the base, and backing plates are fixed to both sides of the base.

Several mounting slots are linearly opened on the lifting frame.

[0007] Furthermore, a rotating rod is provided at the center of the parallel rollers, and a synchronous transmission module is provided on the outside of several sets of parallel rollers. Several transmission shafts connected to the rotating rod are linearly provided inside the synchronous transmission module, and a drive motor is connected to the outside of the synchronous transmission module.

[0009] Furthermore, the top of the leveling roller is linearly equipped with several sets of flashing modules corresponding to the pressure film. The flashing modules include a lithium battery pack, a wireless module and a flashing light that are electrically connected to each other.

[0010] Furthermore, cover plates are fitted on both sides of the airbag sleeve, and a second hydraulic rod is connected to the outside of the cover plate. A spring column is connected to the bottom of the second hydraulic rod, and a spring rubber damper is installed inside the spring column. A second hydraulic cylinder is connected to the top of the second hydraulic rod. The second hydraulic cylinder drives the second hydraulic rod to move the cover plate up and down along the spring column.

[0011] Furthermore, a flexible layer and a flow tube are provided inside the airbag layer, and a flow meter is provided inside the flexible layer.

[0012] Furthermore, the pressure box is equipped with a pressure interaction module, and several sets of air exchange slots are distributed on both sides of the pressure box. The pressure module is connected to the top of the pressure box, and a control screen is installed on the pressure box. The control screen is equipped with a wireless module, and both sides of the pressure module are equipped with wired tubes that communicate with the airbag layer.

[0013] The beneficial effects are: This utility model achieves soft contact by using the airbag sleeve on the outside of the leveling roller in conjunction with the airbag layer, avoiding scratches on the surface of the metal sheet caused by hard extrusion. The pressure is dynamically adjusted by the air pressure box to fit the curvature of the sheet in real time, eliminating the lag in the adjustment of the traditional roller gap, as well as local deformations such as wavy bends and edge waves.

[0014] The pressure interaction module inside the pressure box can adjust the air pressure of the airbag layer in real time according to the strength of the sheet material.

[0023] Please see Figure 2 - Figure 4 In this embodiment, brackets 101 are fixed to the four corners of the bottom of the base 1, shock-absorbing pads 102 are fixed to the top of the base 1, and backing plates 107 are fixed to both sides of the base 1. A lifting frame 103 is provided above the backing plate 107. First hydraulic rods 105 are passed through both ends of the lifting frame 103. A first hydraulic cylinder 106 is connected to the top of the hydraulic rod. The first hydraulic cylinder 106 drives the first hydraulic rod 105 to drive the lifting frame 103 to rise and fall. Several mounting slots 104 are linearly opened on the lifting frame 103. A rotating rod 201 is provided at the center of the parallel roller 2. A synchronous transmission module 202 is provided on the outside of several sets of parallel rollers 2. Several sets of transmission shafts 203 connected to the rotating rod 201 are linearly provided inside the synchronous transmission module 202. A drive motor 204 is connected to the outside of the synchronous transmission module 202. The drive motor 204 drives the synchronous transmission module 202 to drive the parallel roller 2 to rotate.

[0024] Synchronous transmission module 202 structure: adopts a double-row chain to drive the main drive shaft, and the main drive shaft is connected to the rotating rods 201 of each parallel roller 2 through a universal coupling.

[0025] Please see Figure 3 - Figure 4In this embodiment, the leveling adjustment component 3 includes a leveling roller 302, an airbag sleeve 301 is sleeved on the outside of the leveling roller 302, an airbag layer is attached to the inside of the airbag sleeve 301, a leveling plane 304 is fixed to the bottom of the leveling roller 302, a pressure diaphragm is connected to the side end of the airbag layer, and a number of flashing modules 303 corresponding to the pressure diaphragm are linearly arranged on the top of the leveling roller 302. The flashing module 303 includes a lithium battery pack, a wireless module and a flashing light that are electrically connected to each other.

[0026] Please see Figure 4 - Figure 5 In this embodiment, cover plates 305 are fitted on both sides of the airbag sleeve 301. A second hydraulic rod 306 is connected to the outside of the cover plate 305. A spring column 307 is connected to the bottom of the second hydraulic rod 306. A spring rubber damper is provided inside the spring column 307. A second hydraulic cylinder 308 is connected to the top of the second hydraulic rod 306. The second hydraulic cylinder 308 drives the second hydraulic rod 306 to move the cover plate 305 up and down along the spring column 307. A flexible layer and a flow pipe are provided inside the airbag layer. A flow meter is provided inside the flexible layer. A pressure interaction module 401 is provided inside the pressure box 4. Several sets of air exchange slots 402 are distributed on both sides of the pressure box 4. A pressure module 403 is connected to the top of the pressure box 4. A control screen 404 is installed on the pressure box 4. A wireless module is provided inside the control screen 404. A wire tube 405 communicating with the airbag layer is provided on both sides of the pressure module 403.

[0027] Spring rubber damper function: It has a built-in double helical spring (spring wire diameter 3mm, pitch 8mm) and a natural rubber damping layer (thickness 5mm) to achieve the dual function of vibration energy absorption and rapid reset.

[0028] The sheet material is guided into the leveling area by the backing plate 107. The first hydraulic cylinder 106 (model: HOB63, working pressure 21MPa) drives the lifting frame 103 to descend, so that the parallel rollers 2 sets form an initial reference plane with the base 1. The drive motor 204 drives the synchronous transmission module 202 to drive the rotating rod 201 through the transmission shaft 203, driving all the parallel rollers 2 to rotate at the same linear speed (0-30m / min adjustable).

[0029] The airbag layer receives compressed air from the pressure box 4 through the delivery pipe. The pressure diaphragm (piezoresistive sensor, model: HPS-C16, range 0-1MPa) detects the contact pressure in real time and converts it into an electrical signal. The air pressure module 403 automatically adjusts the output pressure according to the preset plate strength parameters (input through the control panel 404, supporting Q235 / SS400 / AL6061 and other material libraries). In conjunction with the second hydraulic cylinder 308, the position of the cover plate 305 is finely adjusted so that the calibration plane 304 forms an adaptive contact angle (0°-15° adjustable) with the plate surface.

[0030] The flow meter monitors changes in gas flow rate. When abnormal fluctuations are detected (such as local bulges in the plate), the air pressure interaction module (PID control algorithm) adjusts the airbag pressure in the corresponding area within 100ms. At the same time, the LED light at the corresponding position of the flashing module 303 flashes to alert the operator.

[0031] The spring rubber damper absorbs the impact energy during the leveling process, ensuring that the dynamic stiffness of the system remains stable within the range of 500-800 N / mm. After leveling is completed, the sheet material is automatically discharged.
