Description

Technical Field

[0001] This utility model relates to the technical field of aluminum coil casting and rolling mills, specifically an inclined aluminum coil casting and rolling mill. Background Technology

[0002] Casting and rolling mills are a new process that directly produces semi-finished billets or finished products from molten metal. During the casting and rolling process, molten metal is poured between two counter-rotating casting rolls, each with internally circulating cooling water. As the rolls rotate, the molten metal is continuously cooled, solidified, and subjected to extrusion and rolling forces, gradually forming a solid thin strip. As an advanced metal processing equipment, casting and rolling mills offer advantages such as simplified processes, reduced energy consumption, and improved quality, and are widely used in the processing and production of various non-ferrous metal materials, including aluminum plates, strips, foils, and aluminum alloy composites.

[0003] In terms of structure, the casting and rolling mill is set with two sets of upper and lower rolls. During operation, both sets of rolls need to be driven to rotate, and one set of rolls needs to have the ability to move and adjust. This means that the traditional gear transmission structure cannot meet the transmission requirements of the rolls. It is necessary to use dual motors or complex transmission structures to drive the operation, resulting in a huge equipment size, which is not conducive to the miniaturization of the equipment. Therefore, an inclined aluminum coil casting and rolling mill is proposed. Utility Model Content

[0025] Two sets of processing rolls 4 are respectively mounted on the upper part of the inclined support 1, following the fixed mounting base 2 and the movable mounting base 3, and guided and supported by the rotating guide column 5 in conjunction with the fixed guide column 6. This allows the strip to be subjected to a more uniform stress distribution during the rolling process, reducing product defects caused by stress concentration, and effectively improving the working stability of the equipment. Specifically, see attached... Figure 1 As shown, the rotating guide post 5 and the fixed guide post 6 are arranged in pairs.

The lower part of the adjusting bolt 16 is rotatably fitted with the fixed mounting base 2, and the upper part of the adjusting bolt 16 is threadedly connected to the screw hole at the lower part of the movable mounting base 3. By turning the adjusting bolt 16, the support height of the movable mounting base 3 can be adjusted, thereby realizing the control and adjustment of the rolling gap between the two sets of processing rolls 4.

[0027] The two sets of rotating guide pillars 5 are connected to the drive motor 7 via transmission gears 8 and drive gears 9, as detailed in the attached diagram. Figure 1 As shown, to facilitate the installation and support of the drive structure, a mounting top 17 is installed on the upper part of the rotating guide column 5 and the fixed guide column 6.

Figure 2 As shown, in order to facilitate transmission installation, two sets of transmission gears 8 are fixedly installed on the upper ends of two sets of rotating guide columns 5 respectively. The two sets of transmission gears 8 are symmetrically meshed on both sides of the drive gear 9 to realize synchronous rotation drive of the two sets of rotating guide columns 5.

[0028] The movable worm 10 and the fixed worm 11 are respectively mounted rotatably on a fixed axis inside the movable mounting base 3 and the fixed mounting base 2, forming a combined working transmission structure with the mounting bases. The two sets of rotating guide columns 5 are connected to the transmission worm gears 12 at the ends of the upper and lower sets of processing rolls 4 via the movable worm 10 and the fixed worm 11, respectively. For details, see attached... Figure 3 As shown, two sets of transmission worm gears 12 are fixedly installed on the end shaft sides of the two sets of processing rolls 4, respectively.

The fixed worm 11 is meshed with the transmission worm gears 12 on the lower side to realize the working drive of the lower processing roll 4. In order to realize the floating installation of the movable worm 10, as shown in the attached figure. Figure 4As shown, guide grooves 13 are evenly arranged on the upper circumference of another set of rotating guide posts 5. A mounting slot 14 is provided through the middle of the movable worm gear 10. The movable worm gear 10 is slidably fitted onto the end post side of the other set of rotating guide posts 5. After installation, the protrusion in the mounting slot 14 slidably engages with the guide groove 13, enabling the transmission of the moving driving force between the movable worm gear 10 and the rotating guide post 5.

The structure is simple, the operation is reliable, and the layout of each component is compact, which can effectively reduce the structural volume of the equipment.

[0029] Working principle or structural principle: During operation, the aluminum plate is installed between the upper and lower sets of processing rollers 4. The drive motor 7 drives the drive gear 9 to rotate, which in turn drives the transmission gears 8 on both sides to rotate synchronously. Under the drive of the two sets of transmission gears 8, the two sets of rotating guide columns 5 rotate synchronously. The movable worm 10 and the fixed worm 11 are respectively fixedly mounted inside the movable mounting base 3 and the fixed mounting base 2, and move synchronously with them. The movable worm 10 and the fixed worm 11 are respectively meshed with the transmission worm gears 12 on the shaft side of the upper and lower sets of processing rollers 4. The movable worm 10 and the fixed worm 11 can drive the upper and lower sets of processing rollers 4 to rotate synchronously in opposite directions. The upper and lower sets of processing rollers 4 complete the casting and rolling of the aluminum plate. When adjusting the thickness of the processing rollers 4, the movable worm 10 moves synchronously with the movable mounting base 3. At the same time, the driving force is stably transmitted through the engagement of the guide groove 13 and the mounting slot 14.

[0030] In summary, this casting and rolling mill adopts a floating worm gear drive transmission structure, with one side guide column serving as the working drive structure for the processing rolls 4. Two sets of rotating guide columns 5 are driven by a transmission gear 8 in conjunction with a drive gear 9. Movable worm gears 10 and fixed worm gears 11 are respectively installed on the upper part of the two sets of rotating guide columns 5. The movable worm gears 10 and fixed worm gears 11 respectively complete the working drive of the upper and lower sets of processing rolls 4. Only a single motor is needed to complete the working drive of the upper and lower sets of processing rolls 4, and floating drive of the upper processing roll 4 can be achieved. The structure is simple, reliable, and the layout of each component is compact, which can effectively reduce the structural volume of the equipment. Furthermore, the processing rolls 4 are set at an inclination, and the two sets of processing rolls 4 are installed at a fixed inclination angle, which can make the strip subject to a more uniform stress distribution during the rolling process, reduce product defects caused by stress concentration, and effectively improve the working stability of the equipment.
