Description

Technical Field

[0001] This utility model relates to the field of hot rolling technology, specifically to a roller support positioning structure for a hot rolling device for steel coils. Background Technology

[0002] Hot rolling is the opposite of cold rolling. Cold rolling is rolling performed below the recrystallization temperature, while hot rolling is rolling performed above the recrystallization temperature. Simply put, a steel billet is heated and then rolled several times, then trimmed and straightened to become a steel plate. This is called hot rolling. It can significantly reduce energy consumption and costs. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation.

[0003] During hot rolling, steel coils need to be extruded multiple times through multiple hot rolling units to be extended into steel coils. Between each hot rolling unit, roller supports are needed to support and transport the steel coils. However, the lack of positioning structures on both sides of the roller supports makes it possible for the steel coils supported and transported on the roller supports to deviate from their intended path. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a roller support positioning structure for a hot rolling mill for steel coils, which can prevent the steel coils from deviating during the conveying process.

[0005] This utility model provides the following technical solution: a roller support positioning structure for a hot rolling mill of steel coils, including a roller support body. Multiple housings are fixedly connected to the inner wall of the roller support body. Each housing is provided with two screws with opposite threads. One end of the two screws is fixedly connected together, and a slider is threadedly sleeved on the outer wall of each screw. A limit component is provided on one side of the slider. One end of the screw passes through the roller support body and extends to the outside of the roller support body. A control component is sleeved on the outer wall of the screw located outside the roller support body.

A threaded hole is opened on the upper surface of the slider, and one end of the rotating rod is threadedly connected to the inner wall of the threaded hole. A nut is threadedly sleeved on the outer wall of the rotating rod.

[0007] Furthermore, the control component includes a sleeve fitted on the outer wall of the lead screw, and a gear is fixedly fitted on the outer wall of the sleeve. A bolt is threaded onto the outer wall of the sleeve, and one end of the bolt passes through the sleeve and abuts against the lead screw. A chain is fitted on the outer wall of a plurality of gears, and the chain drives the plurality of gears.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a roller support positioning structure for a hot rolling mill of steel coils, including a roller support body 1. Multiple housings 2 are fixedly connected to the inner wall of the roller support body 1. Each housing 2 is provided with two screw rods 3 with opposite threads. One end of the two screw rods 3 is fixedly connected together, and the outer wall of each screw rod 3 is threaded with a slider 4. A limit component is provided on one side of the slider 4. One end of the screw rod 3 passes through the roller support body 1 and extends to the outside of the roller support body 1. A control component is sleeved on the outer wall of the screw rod 3 located outside the roller support body 1.

[0020] As can be seen from the above structure, by setting the limiting component, the steel coil supported on the roller support body 1 can be limited, thereby avoiding the problem of the steel coil possibly running around during the conveying process. At the same time, by setting the control component, the movement of the limiting component can be controlled and the position of the limiting component can be adjusted so that the device can limit the steel coil when producing steel coils of different widths, thereby improving the practicality of the device.

[0021] Furthermore, the limiting component includes a guide wheel 5 disposed on one side of the slider 4, and a rotating rod 6 is sleeved on the inner wall of the guide wheel 5. A threaded hole is opened on the upper surface of the slider 4, and one end of the rotating rod 6 is threadedly connected to the inner wall of the threaded hole. A nut 7 is threadedly sleeved on the outer wall of the rotating rod 6. By setting the rotating rod 6 to cooperate with the guide wheel 5, when the steel coil is conveyed in the roller support body 1, the guide wheel 5 can block and limit the steel coil to avoid the problem of the steel coil possibly running around during the conveying process. In use, rotating the lead screw 3 can drive the slider 4 and the limiting component to move, thereby connecting the position of the limiting component.

[0022] Furthermore, the control component includes a sleeve 8 fitted onto the outer wall of the lead screw 3, and a gear 9 is fixedly fitted onto the outer wall of the sleeve 8. A bolt 10 is threaded onto the outer wall of the sleeve 8, and one end of the bolt 10 passes through the sleeve 8 and abuts against the lead screw 3. A chain 11 is fitted onto the outer wall of multiple gears 9, and the chain 11 drives and connects multiple gears 9. By setting the gears 9 and the chain 11 to work together, multiple lead screws 3 can be driven and connected. Thus, when one lead screw 3 is rotated, the rotating lead screw 3 can drive multiple lead screws 3 to rotate simultaneously through the gears 9 and the chain 11, so as to adjust multiple limit components at the same time, thereby facilitating the adjustment of the limit components.

[0023] Furthermore, the control component is covered with a housing 12, and the housing 12 is fixedly connected to the roller bracket body 1. A baffle 13 is detachably connected to one side wall of the housing 12. One end of a lead screw 3 passes through the baffle 13 and extends to the outside of the baffle 13. The control component can be protected by the housing 12.

[0024] Furthermore, one end of the lead screw 3 located outside the baffle 13 is provided with an internal hexagonal hole 14; by providing the internal hexagonal hole 14, an internal hexagonal wrench can be used to engage with the internal hexagonal hole 14 to rotate one of the lead screws 3.

[0025] Furthermore, grooves are provided at both ends of the guide wheel 5, and bearings 15 are fixedly connected to the inner walls of the grooves. The inner walls of the bearings 15 are fixedly connected to the rotating rod 6. By setting the bearings 15, the guide wheel 5 can rotate more stably.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
