Description

Technical Field

[0001] This utility model belongs to the technical field of steel coil leveling machines, and particularly relates to a horizontal integral separation mechanism for the upper and lower straightening roller units of a steel coil leveling machine. Background Technology

[0002] The straightening rollers in a steel coil leveling machine are the core working components of the equipment. They are mainly used to level metal sheets (such as steel coils) by mechanical force to eliminate defects such as bending, wavy, and warping that occur during rolling, transportation, or cooling, thus restoring the flatness of the material. The straightening rollers are the roller-shaped components in the straightening machine that come into direct contact with the metal sheet. Through rotation and pressure, they apply reverse bending deformation to the sheet, causing it to undergo elasto-plastic deformation and ultimately achieve a flat state. They eliminate sheet defects by correcting longitudinal bending, transverse wavy, and local warping after the steel coil is unrolled, thereby improving the flatness of the sheet.

[0003] In existing technologies, the lower straightening rollers of traditional steel coil leveling machines generally adopt a fixed installation structure, that is, the lower straightening rollers are directly fixed inside the lower frame through bearing seats, and the relative positions of the upper and lower straightening rollers remain unchanged. This structure restricts the operating space during maintenance and cleaning operations, and it is difficult to expose key parts. Because the lower straightening rollers are fixed inside the frame and surrounded by the frame frame and transmission components, the workers can only work through the narrow gap between the upper and lower straightening rollers. Key areas such as the inner side of the roller surface and the connection between the roller shaft and the bearings cannot be fully exposed, resulting in incomplete cleaning. Utility Model Content

[0004] This utility model aims to solve the problems existing in the prior art and proposes a horizontal integral separation mechanism for the upper and lower straightening roller units of a steel coil leveling machine.

[0005] This utility model provides a horizontal integral separation mechanism for the upper and lower straightening roller units of a steel coil leveling machine, comprising: a lower machine platform and an upper machine platform. A lifting column driving device is provided on the lower machine platform, and an upper mounting platform is provided below the upper machine platform. The driving end of the lifting column driving device is connected to the upper mounting platform. A slide rail is provided on the lower machine platform, and a lower mounting platform is translatably arranged on the slide rail.

The upper machine platform has a first inner cavity, and a rotatable long worm shaft is provided on one side of the first inner cavity for driving the worm wheel to rotate. The lower machine platform is provided with a second inner cavity, and a rotatable lead screw is provided in the second inner cavity. The worm gear is connected to a worm structure provided at one end of the lead screw through a worm gear shaft. A lead screw seat is movably disposed within the second inner cavity. The helical line of the inner hole of the lead screw seat engages with the helical line of the lead screw shaft, and the upper end face of the lead screw seat is connected to the bottom end of the lower mounting platform.

[0006] Preferably, a tailstock is provided on one side of the upper and lower machine platforms, and the long worm shaft, worm structure and worm wheel shaft are all provided in the tailstock. Worm wheels are provided at both ends of the worm wheel shaft, and the two worm wheels are respectively connected to the long worm shaft and the worm structure for transmission.

[0007] Preferably, it further includes a rotating assembly, which includes a bracket disposed on one side of the upper platform, a connecting rod rotatably disposed on the bracket, and one side of the connecting rod movably passes through the upper platform and is connected to one end of the long worm shaft.

[0008] Preferably, the other side of the connecting rod is configured with a square opening structure.

[0009] Preferably, a square-mouth wrench is fitted around the outer periphery of the square-mouth structure.

[0010] Preferably, a support is provided on one side of the tailstock, a rotary motor is provided on the support, a first pulley is provided on the drive end of the rotary motor, a plurality of second pulleys are rotatably provided on one side of the tailstock, the first pulley is connected to the plurality of second pulleys through a transmission belt, a universal joint is provided on one side of the plurality of second pulleys, and a shaft end opening slot is provided on one side of the plurality of lower straightening rollers, the universal joints are adapted to the shaft end opening slots.

[0013] Compared with the prior art, the horizontal integral separation mechanism of the upper and lower straightening roller units of the steel coil leveling machine described in this utility model has the following advantages: The connection structure between the lifting column drive device of the lower platform and the upper mounting platform allows for flexible adjustment of the height of the upper mounting platform, thereby controlling the distance between the upper and lower straightening rollers. This adapts to the leveling needs of steel coils of different thicknesses, significantly improving the equipment's versatility and applicability. The lower mounting platform is horizontally mounted on the slide rail. Combined with the long worm shaft, the worm structure on the lead screw, and the transmission structure between the lead screw and the lead screw seat, simply driving the long worm shaft via the rotating component allows the transmission component to rotate the worm structure on the lead screw. This, in turn, causes the lead screw to push the lead screw seat, moving the lower mounting platform horizontally along the slide rail, achieving the overall horizontal separation of the lower straightening roller unit. This separation method eliminates the need to disassemble individual straightening rollers, greatly simplifying the cleaning, inspection, and replacement process, reducing equipment downtime. The overall structure employs a mechanical transmission design, ensuring high transmission stability and guaranteeing precise position control of the upper and lower straightening roller units during separation and resetting. This prevents component misalignment from affecting leveling accuracy and ensures consistent steel coil leveling quality. Attached Figure Description

[0019] Reference Figures 1-5 A horizontal integral separation mechanism for the upper and lower straightening roller units of a steel coil leveling machine includes: a lower platform 2 and an upper platform 1, the upper platform 1 being located above the lower platform 2. A lifting column drive device 3 is provided on the lower platform 2. An upper mounting platform 4 is movably provided below the upper platform 1. The driving end of the lifting column drive device 3 is connected to the upper mounting platform 4. A slide rail 14 is provided on the lower platform 2. A lower mounting platform 5 is translatably provided on the slide rail 14. A plurality of upper straightening rollers 6 and a plurality of lower straightening rollers 7 are rotatably provided on the upper mounting platform 4 and the lower mounting platform 5, respectively. The upper platform 1 has a first inner cavity 8. A long worm shaft 9 is rotatably mounted on one side of the first inner cavity 8. A rotating assembly is provided on one side of the long worm shaft 9 to drive the long worm shaft 9 to rotate. The lower platform 2 has a second inner cavity 10. A lead screw 18 is rotatably mounted in the second inner cavity 10. One end of the lead screw 18 is rotatably connected to the inner wall of the second inner cavity 10 through a bearing. A worm structure 12 is fixedly connected to one end of the lead screw 18. The long worm shaft 9 is connected to the worm structure 12 on the lead screw 18 through a transmission assembly. A lead screw seat 13 is sleeved on the outer periphery of the lead screw 18 and is translatably mounted in the second inner cavity 10. The lead screw 18 movably passes through the lead screw seat 13 and is threadedly connected to the lead screw seat 13. The top end of the lead screw seat 13 is connected to the bottom end of the lower mounting platform 5 to drive the lower mounting platform 5 to translate along the slide rail 14.

[0020] The lifting column drive device 3 includes several columns mounted on the machine platform and a hydraulic drive device (e.g., a hydraulic cylinder) for driving the columns to rise. The lifting column drive device 3 is existing technology and will not be described in detail here.

[0021] In use, this device allows for flexible adjustment of the height of the upper mounting platform 4 via the connection structure between the lifting column drive device 3 of the lower platform 2 and the upper mounting platform 4. This, in turn, controls the distance between the upper straightening roller 6 and the lower straightening roller 7, adapting to the leveling needs of steel coils of different thicknesses and significantly improving the equipment's versatility and applicability. The lower mounting platform 5 is laterally mounted on the slide rail 14. Combined with the transmission structure of the long worm shaft 9, the worm structure 12 on the lead screw, and the lead screw 18 and lead screw seat 13, the long worm shaft 9 can be driven by rotating the assembly, thereby driving the lead screw through the transmission assembly. The worm gear structure 12 on the rod rotates, which in turn causes the lead screw 18 to push the lead screw seat 13 to drive the lower mounting platform 5 to move horizontally along the slide rail 14, thereby achieving the overall horizontal separation of the lower straightening roller 7 unit. This separation method does not require disassembling individual straightening rollers, which greatly simplifies the cleaning, inspection and replacement process of straightening rollers, reduces equipment downtime for maintenance, and the overall structure adopts a mechanical transmission design with high transmission stability. It can ensure that the upper and lower straightening roller units maintain precise position control during separation and resetting, avoid the impact of component offset on the straightening accuracy, and ensure the consistency of steel coil straightening quality.

[0022] In the example of this application, the transmission assembly includes a tailstock 15 disposed on one side of the upper platform 1 and the lower platform 2. The tailstock 15 is fixedly connected to the upper platform 1 and provides support for the upper platform 1. An installation groove is provided in the tailstock 15. One end of the long worm shaft 9 and the worm structure 12 both movably pass through the tailstock 15 and extend into the tailstock 15. A worm wheel shaft 17 is rotatably disposed in the installation groove. That is, both ends of the worm wheel shaft 17 are rotatably connected to the upper and lower side walls of the installation groove respectively through bearings. Worm wheels 32 are respectively provided at both ends of the worm wheel shaft 17. The two worm wheels 32 are respectively connected to the corresponding long worm shaft 9 and worm structure 12 for transmission.

[0023] As a preferred example of this utility model, the worm wheels 32 on both sides of the worm shaft 17 inside the tailstock 15 are respectively connected to the long worm shaft 9 and the worm structure 12 on the lead screw 18, forming a compact and precise transmission link. This avoids the power loss or transmission deviation problems caused by the dispersion of components in traditional transmission methods. The structure of the tailstock 15 and the mounting groove can protect the connection parts of the worm shaft 17, the long worm shaft 9 and the worm structure 12 on the lead screw, preventing external dust and impurities from entering the transmission structure, reducing component wear and extending the service life of the transmission components.

[0024] In the example of this application, the rotating assembly includes a bracket 19 disposed on one side of the upper machine platform 1. A connecting rod 20 is rotatably disposed on the bracket 19. One side of the connecting rod 20 movably passes through the upper machine platform 1 and is connected to one end of the long worm shaft 9. A square opening structure 21 is provided on the other side of the connecting rod 20. A square opening wrench 22 is sleeved on the outer periphery of the square opening structure 21.

[0025] As a preferred example of this utility model, the connecting rod 20 on the bracket 19 connects the long worm shaft 9 to the external square structure 21. The operator only needs to drive the square structure 21 to drive the connecting rod 20 and the long worm shaft 9 to rotate, thereby triggering the separation action of the upper and lower straightening roller 7 units. The design of the square wrench 22 sleeved on the outer periphery of the square structure 21 increases the force-bearing area during operation, reduces the operating force of the operator, and avoids hand fatigue caused by long-term operation.

[0026] In the example of this application, a rectangular groove is provided on one side of the square wrench 22, the rectangular groove is adapted to the square structure 21, and a handle is provided on one side of the square wrench 22.

[0027] As a preferred example of this utility model, the square-mouth wrench 22 is adapted to the square-mouth structure 21 through a rectangular groove. The rectangular structure can effectively prevent relative rotation between the square-mouth wrench 22 and the square-mouth structure 21, ensuring that when the operator turns the handle, the power can be fully transmitted to the square-mouth structure 21 and the connecting rod 20, avoiding operation delay or power loss caused by slippage. The handle is designed in accordance with ergonomics, making it more comfortable for the operator to hold and easier to apply force. Especially when it is necessary to rotate the long worm shaft 9 for a long time or frequently, it can significantly reduce hand discomfort.

[0028] In the example of this application, a support 25 is provided on one side of the tailstock 15, a rotary motor 26 is provided on the support 25, a first pulley 27 is provided at the drive end of the rotary motor 26, a plurality of second pulleys 28 are rotatably provided on one side of the tailstock 15, the first pulley 27 is connected to the plurality of second pulleys 28 through a transmission belt, a connecting member 29 is provided on one side of the plurality of second pulleys 28, and a shaft end opening slot 30 is provided on one side of the plurality of lower straightening rollers 7, and the connecting member 29 is adapted to the shaft end opening slot 30.

[0029] As a preferred example of this utility model, the rotary motor 26 on the bracket 19 is connected to the second pulley 28 via the first pulley 27 and the transmission assembly, providing stable power to the lower straightening roller 7. The fitting design of the connector 29 and the shaft end opening slot 30 of the lower straightening roller 7 allows the connector 29 to maintain a reliable connection or be easily separated from the shaft end opening slot 30 when the lower mounting platform 5 drives the lower straightening roller 7 to move horizontally. During normal operation of the equipment, the connector 29 and the shaft end opening slot 30 are tightly fitted, and the power of the rotary motor 26 can be transmitted to the lower straightening roller 7 via the transmission belt and the connector 29, ensuring the stable rotation of the lower straightening roller 7 and guaranteeing the leveling effect of the steel coil. When maintenance of the lower straightening roller 7 is required, the horizontal movement of the lower mounting platform 5 causes the lower straightening roller 7 to separate from the connector 29. The entire separation of the lower straightening roller 7 can be achieved without disassembling the power transmission structure. After maintenance is completed, when the lower mounting platform 5 is reset, the connector 29 can be quickly refitted with the shaft end opening slot 30, realizing the rapid restoration of the power transmission.

[0030] In the example of this application, the universal joint is a universal connector, and a plug end 31 is provided on one side of the universal connector. Both the shaft end opening slot 30 and the plug end 31 are rectangular.

[0031] As a preferred example of this utility model, the connector 29 adopts a universal joint, which, together with the rectangular plug end 31 and the shaft end slot 30, further enhances the flexibility and reliability of power transmission. The universal joint has multi-angle transmission capability, which can effectively compensate for slight positional deviations that may occur in the lower straightening roller 7 during horizontal movement or long-term operation, avoid power transmission interruption or component damage caused by component misalignment, and ensure the stability and smoothness of power transmission. The rectangular plug end 31 and the shaft end slot 30 can prevent relative rotation between the lower straightening roller 7 and the connector 29 during rotation, ensuring power transmission efficiency. At the same time, the rectangular connection method is convenient for disassembly and assembly. When the lower straightening roller 7 is horizontally separated or reset, the plug end 31 can quickly connect or separate from the shaft end slot 30 without complicated operation, further simplifying the maintenance process and improving the ease of operation and reliability of the equipment.

[0032] In the example of this application, a plurality of the upper straightening rollers 6 and a plurality of lower straightening rollers 7 are arranged alternately.

[0033] As a preferred example of this utility model, the staggered arrangement of several upper straightening rollers 6 and several lower straightening rollers 7 is a key design to ensure the leveling quality of steel coils. The staggered layout allows the steel coil to be subjected to alternating pressure in the up and down directions when passing through the straightening roller unit, effectively eliminating the internal stress of the steel coil, correcting defects such as bending and wrinkles of the steel coil, and improving the flatness and straightness of the steel coil.

[0034] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
