Description

Technical Field

[0001] The present invention relates to the technical field of metal rolling, in particular to aluminum alloy plate and strip rolling processing equipment. Background Art

[0002] The rapid development of industries such as aerospace, automotive, and electronics is driving increasing demand for aluminum alloy sheet and strip. Due to their excellent mechanical properties, corrosion resistance, and lightweight characteristics, aluminum alloy sheet and strip are widely used in these fields. However, traditional aluminum alloy sheet and strip rolling equipment has numerous shortcomings, making it difficult to meet the high efficiency, high precision, and high quality requirements of modern industrial production.

[0003] As disclosed in application No. 202411528245.1, an aluminum alloy plate and strip rolling processing equipment and its processing technology are provided, in which a cleaning seat capable of sliding relative to the upper and lower parts of the plate is arranged in front of the roller. When the plate is squeezed between the rollers and moves forward, the two cleaning seats clamp and push the plate toward the roller, thereby increasing the feeding strength of the plate and reducing the relative sliding between the plate and the roller. At the same time, when the cleaning seat approaches the roller, it is pushed by the elastic force of the reset spring to move away from the roller. The cleaning seat wipes the upper and lower parts of the plate to remove impurities on the surface of the plate, thereby enhancing the smoothness of the plate surface and ultimately achieving the effect of plate cleaning and auxiliary clamping and feeding.

[0004] However, during the rolling process, impurities and lubricating oil are easily attached to the surface of the rolling rollers and the plate and strip. The cleaning function of traditional equipment is not perfect, and it is difficult to completely remove these attachments, resulting in poor surface quality of the plate and strip after rolling, affecting the appearance and performance of the product. Therefore, an aluminum alloy plate and strip rolling processing equipment is proposed to solve the above problems. Summary of the Invention

[0029] Working principle: When in use, the aluminum alloy plate and strip to be rolled is unwound from the unwinding device and placed on the transmission roller 7 for transmission. It then contacts the guide roller 53 and passes again between the two scrapers 462 and the rolling roller 43 for unwinding and rolling. First, a gear box and a motor are installed on the back of the two cleaning shafts 61, and the sleeves of the two cleaning shafts 61 are connected to each other by a connecting rod, so that the two cleaning shafts 61 can move up and down synchronously. At the same time, by starting the motor and driving the two cleaning shafts 61 to rotate, the two brush cylinders 62 will be driven to rotate, so that the upper and lower surfaces of the aluminum alloy plate and strip can be cleaned, and the upper brush cylinder 62 is in contact with the outer wall of the guide roller 53, so that the outer wall of the guide roller 53 can also be cleaned, thereby improving the cleaning effect and preventing burrs and impurities from affecting the rolling of the aluminum alloy plate and strip; When the cam 63 no longer pushes the lever 64 downward, the spring 3 55 and the spring 2 66 push the guide support rod 54 and the lever 65 upward, thereby pushing the cleaning shaft 61 and the guide shaft 52 upward, thereby continuously floating the brush cylinder 62 and the guide roller up and down, thereby further improving the cleaning effect and the tension during the guide. Furthermore, oil is pumped into the liquid inlet pipe 464 by an external pumping device, and enters the spray pipe 461 through the mounting seat 463 and the elastic connecting pipe 465 to spray the upper and lower surfaces of the aluminum alloy plate and strip. Subsequently, the motor installed on one side of the upper movable shaft 42 is started to work, thereby driving the upper rolling roller 43 to rotate, thereby cooperating with the lower rolling roller 43 to roll the metal plate and strip; at the same time, according to the thickness of the rolled plate and strip, the movement trend of the arc-shaped connecting rod 56 synchronizer is realized, and the distance between the two rolling rollers 43 is synchronously and dynamically adjusted through the support rod 44 and the spring 1 45, so as to achieve the effect of rolling the aluminum alloy plate and strip; When the rolling roller 43 rotates, it will contact two scrapers 462. The scrapers 462 can scrape off the oil box impurities attached to the outer wall of the rolling roller 43, so that they fall off along the rectangular holes on its outer wall, avoiding the attachment of impurities to the outer wall of the rolling roller 43, which affects the rolling quality when rolling aluminum alloy plates and strips. Through the L-shaped connecting rod 466, it can synchronously follow the movement of the rolling roller 43 below, and push it to fit the surface of the rolling roller 43 through the coil spring, so that it can better adapt to the cleaning of the outer wall of the rolling roller 43 and improve the cleaning effect.
