Abstract
Description
Technical Field
[0001] This utility model relates to the field of stainless steel processing technology, and in particular to a hot rolling device for stainless steel coils. Background Technology
[0002] Stainless steel coil is a coiled product made by rolling thin stainless steel sheets. The production of stainless steel coil requires a series of processes, including steelmaking and hot rolling. First, the stainless steel raw materials are melted to make steel billets. Then, the steel billets are processed into thin sheets through hot rolling or cold rolling processes. Finally, the thin sheets are rolled into coils. Hot-rolled coils are generally thicker and have relatively poor surface quality, but they have high strength and good toughness.
[0003] A stainless steel hot rolling mill is a device used to process stainless steel billets into stainless steel coils through a hot rolling process. The stainless steel billet is first heated in a heating furnace to a set temperature and is in a thermoplastic state. Then it is conveyed to the roughing mill. Under the pressure of the roughing mill rolls, the billet undergoes plastic deformation. The finishing mill precisely adjusts the rolls and controls the parameters to improve the dimensional accuracy and surface quality of the strip. However, in existing stainless steel hot rolling mills, the dimensional accuracy and surface quality of the products are relatively low. During the hot rolling process, due to the complex deformation of the metal at high temperatures, it is difficult to accurately control the parameters of the strip thickness, width, and shape, which easily leads to problems such as thickness deviation, width fluctuation, and poor shape.

[0032] Specifically, motor 4 is fixed to the rear side of fixed plate 3. After starting, it drives the rolling roller 5 to rotate and move linearly along rack 7, achieving initial shaping of the stainless steel coil. The support roller 8 at the bottom of the rolling roller 5 ensures uniform force distribution and improves rolling accuracy. The transmission roller 9 cooperates with the conveying roller 10 to further roll and convey the initially rolled coil.

In addition, cover plate 18 is fixedly connected to the top of fixed plate 3.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The winding mechanism 2 includes a fixed frame 201, which is fixedly connected to the top left side of the support frame 1. A motor 202 is fixedly connected to the top rear side of the fixed frame 201. A winding frame 203 is fixedly connected to the output end of the motor 202. A winding drum 204 is fixedly connected to the middle of the inner wall of the winding frame 203. A motor 205 is fixedly connected to the top right side of the fixed frame 201. An adjusting frame 206 is fixedly connected to the output end of the motor 205. An auxiliary frame 207 is rotatably connected to one side of the outer wall of the adjusting frame 206. A fixing ring 21 is fixedly connected to the front side of the outer wall of the winding frame 203. A pin 22 passes through the middle of the inner wall of the fixing ring 21. Slide grooves 23 are provided on both the front and rear sides of the outer wall of the adjusting frame 206. An auxiliary wheel 24 is slidably connected to the middle of the inner wall of each of the two slide grooves 23.
[0034] Specifically, the fixed frame 201 is located on the top left side of the support frame 1, providing a mounting base for the winding component. The motor 202 is mounted on the rear top of the fixed frame 201. After starting, it drives the winding frame 203 to rotate via torque, thereby causing the winding drum 204 to rotate synchronously. When the winding drum 204 rotates, the stainless steel coil is wound and wound up. A motor 205 is mounted on the other side of the fixed frame 201, which controls the movement of the adjusting frame 206 to adapt to winding requirements. The adjusting frame 206 is connected to the auxiliary frame 207, which changes position when the adjusting frame 206 moves. Position or angle, guiding and supporting the stainless steel coil, ensuring smooth winding process and improving winding quality, a fixing ring 21 is connected to the front side of the winding frame 203. The inner wall of this fixing ring 21 is designed with a through pin 22, which plays an important role in fixing and facilitating disassembly and maintenance. The outer wall of the adjustment frame 206 is designed with sliding grooves 23 on both the front and rear sides. The inner wall of these sliding grooves 23 is equipped with auxiliary wheels 24 that can slide freely, so that the adjustment frame 206 can be adjusted more flexibly during use and reduce wear between structures.
[0035] Reference Figure 1 , Figure 2 and Figure 3 The outer walls of the support frame 1 are fixedly connected with baffles 19. The top of the outer walls of motor 2 and motor 3 are fixedly connected with insulation boards 20. The bottom left and right sides of motor 1 202 are fixedly connected with fixing blocks 25. The bottom of the outer wall of the fixing block 25 is fixedly connected with a buffer pad 26. The bottom of the support frame 1 is fixedly connected with four corners of the bottom with foot pads 27. The inner wall of the foot pad 27 has multiple connection holes 28.
[0036] Specifically, the baffles 19 fixed around the outer wall of the support frame 1 can block the debris splashed out during hot rolling and prevent foreign objects from accidentally colliding with the device components, thus playing a protective role. The insulation plates 20 on the top of the outer walls of motor 2 4 and motor 3 11 can reduce the harm of heat to the motor operation, maintain a relatively stable operating temperature of the motor, improve the working efficiency of the motor and extend its service life. The left and right fixed blocks 25 at the bottom of motor 1 202 and the buffer pads 26 below them can effectively absorb and buffer the vibration when the motor is running, reduce the impact of motor vibration on the fixed frame 201 and the entire device, and ensure the smooth operation of the equipment. The foot pads 27 at the four corners at the bottom of the support frame 1 provide support for the device, keeping the device level and stable. On the other hand, the multiple connecting holes 28 in the middle of the inner wall of the foot pads 27 facilitate the further fixing of the device to the ground or installation foundation by bolts and other connecting parts, enhancing the stability of the device during operation and preventing the device from shifting due to external forces or other factors.
[0037] Working principle: Motor 4 is fixed to the rear side of the outer wall of the fixed plate 3. After starting, its output end drives the rolling roller 5 to rotate, and the gear 6 at the front end of the rolling roller 5 rotates accordingly. Since the gear 6 is meshed with the rack 7 on the front side of the fixed plate 3, the rolling roller 5 moves linearly along the direction of the rack 7 while rotating. This linear motion can apply rolling force of different positions and intensities to the stainless steel coil according to the rolling requirements, realizing the initial rolling and shaping of the coil. A support roller 8 is set at the bottom of the rolling roller 5, which provides support for the rolling roller 5 and ensures that the rolling process is smooth. The rolling roller 5 is subjected to uniform force, avoiding deformation due to uneven force and improving the rolling accuracy and quality. The drive roller 9 on the right side of the inner wall of the fixed plate 3 cooperates with the conveying roller 10. When the drive roller 9 rotates, it drives the conveying roller 10 to rotate. Together, they further roll and convey the stainless steel coil after the initial rolling by the rolling roller 5, so that the coil gradually reaches the required thickness and shape during the rolling process. The motor 11 is fixed on the rear side of the outer wall of the fixed plate 3. After starting, the power at its output end is transmitted to the correction mechanism 13 through the universal joint 12. The universal joint 12 can provide a certain degree of correction. The flexible transmission within the angular range ensures that the power of motor 11 can be smoothly transmitted to the correction mechanism 13 at different positions and angles. Driven by the power, the correction mechanism 13 adjusts the position of the stainless steel coil during the rolling process. During rolling, the coil may shift. The correction mechanism 13 detects the positional deviation of the coil and makes corresponding adjustments based on the deviation to ensure that the coil is always in the correct rolling position, improving the rolling accuracy and quality. A slidable moving block 14 is provided on the inner bottom wall of the fixed plate 3, and multiple rotating shafts 15 are rotatably connected to one side of the outer wall of the moving block 14. When it is necessary to adjust the position of certain components during the rolling process, it can be achieved by pushing the moving block 14 to slide on the inner bottom wall of the fixed plate 3. The rotating shaft 15 can assist the sliding of the moving block 14, reduce the friction during the sliding process, and make the movement smoother. The scale 16 set on one side of the outer wall of the moving block 14 is used to accurately measure the sliding distance of the moving block 14. When adjusting the position of the component, the operator can accurately control the sliding distance of the moving block 14 according to the reading of the scale 16, thereby achieving precise adjustment of the position of the rolled component and ensuring the accuracy and stability of the rolling process.
[0038] The fixed frame 201, located on the top left side of the support frame 1, provides the mounting base for all winding-related components. Motor 202 is mounted on the top rear side of the fixed frame 201. When motor 202 starts, the torque generated at its output end is transmitted to the winding frame 203, causing it to rotate. Since the winding drum 204 is fixed to the middle of the inner wall of the winding frame 203, the rotation of the winding frame 203 will cause the winding drum 204 to rotate synchronously. At this time, one end of the stainless steel coil, rolled by the hot rolling device, is wound onto the winding drum 204. As the winding drum 204 continues to rotate, the stainless steel coil is continuously wound up, achieving the collection of the coil. The motor 205, located on the top right side of the fixed frame 201, drives the adjusting frame 206 at its output end during operation. The motor 205 can precisely control the rotation angle and movement position of the adjusting frame 206 according to actual winding requirements. For example, if the stainless steel coil is not neatly wound during winding, the motor 205 can adjust the state of the adjusting frame 206. The auxiliary frame 207, which is rotatably connected to one side of the outer wall of the adjusting frame 206, will change its position or angle accordingly when the adjusting frame 206 moves. The auxiliary frame 207 can guide, support, or fine-tune the tension of the stainless steel coil being wound. For example, when the coil tends to deviate during winding, the auxiliary frame 207 can guide the coil back to the correct winding path by changing its own position, ensuring the smooth progress of the coil winding process and improving the winding quality.
