Description

Technical Field

[0001] This application relates to the field of aluminum sheet, strip and foil production technology, specifically a high-precision aluminum sheet, strip and foil casting and rolling production line. Background Technology

[0002] Aluminum sheet, strip, and foil are important metallic materials with wide applications in aerospace, automotive manufacturing, electronic equipment, and many other fields. As various industries continue to demand higher quality and precision from aluminum sheet, strip, and foil, greater challenges are being placed on the performance and stability of high-precision aluminum sheet, strip, and foil casting and rolling production lines.

[0003] Traditional aluminum sheet, strip, and foil casting and rolling production lines have several shortcomings in the production process. For example, after prolonged use, aluminum shavings and other impurities easily accumulate on the sidewalls of the extrusion rollers. These impurities not only affect the extrusion effect on the aluminum sheet, strip, and foil, leading to decreased product precision, but may also scratch the surface of the aluminum sheet, strip, and foil during extrusion, reducing product quality. Furthermore, existing production lines have complex drive structures, resulting in high maintenance costs, and their transmission efficiency needs further improvement. In addition, during operation, some components, such as the drive motor, generate heat; if this heat is not dissipated in a timely manner, it will affect the equipment's lifespan and stability.

[0004] Therefore, developing a high-precision aluminum sheet, strip, and foil casting and rolling production line that can effectively clean the extrusion rollers, has high transmission efficiency, and good heat dissipation is of great practical significance. Utility Model Content

[0028] Above each upper extrusion roller 6 and below each lower extrusion roller 6, there is a scraper 7 for cleaning impurities and residues on the side wall of the extrusion roller 6. A telescopic assembly 13 is installed on the inner side wall of the operation box 1. The telescopic assembly 13 can drive the scraper 7 to move up and down. The telescopic assembly 13 drives the scraper 7 to move and contact the side wall of the extrusion roller 6, thereby cleaning the extrusion roller 6.

[0031] Example 2:

[0032] like Figure 1-4 As shown, this utility model discloses another technical solution, a high-precision aluminum plate, strip and foil casting and rolling production line, which differs from embodiment 1 in that the inner side wall of the operation box 1 is provided with mounting grooves 15 at both ends of each scraper 7, the fixed end of the telescopic component 13 is vertically fixedly installed in the mounting groove 15, and the telescopic end of the telescopic component 13 is fixedly connected to a moving block 14, and the two ends of the scraper 7 are detachably fixedly connected to two oppositely arranged moving blocks 14 by bolts.

[0033] Specifically, the inner sidewall of the mounting groove 15 is symmetrically provided with limiting grooves 17, and the two ends of the moving block 14 are integrally provided with limiting sliders 16.
