Description

Technical Field

[0001] This utility model belongs to the technical field of hot rolling equipment, and more specifically, it relates to a hot rolling device for stainless steel flat plates. Background Technology

[0002] In the industrial production process of stainless steel flat plates, hot rolling is an indispensable core process. This process, through rolling and shaping at high temperatures, directly determines the basic mechanical properties and surface flatness of the stainless steel flat plates. The core performance characteristics of the hot rolling equipment, such as operational stability, heating uniformity, and rolling precision, not only play a decisive role in key quality indicators such as plate thickness tolerance and grain uniformity, but also directly affect production cycle time and unit energy consumption, thereby influencing the production efficiency and overall benefits of the entire production line.

[0003] Based on the above, most of the existing hot rolling mill work rolls have a fixed structure, which makes it impossible to flexibly adjust the gap between the rolls according to the thickness of the stainless steel billet. This makes it difficult for the equipment to adapt to diverse production needs, which not only limits its application scenarios, but also further reduces the overall applicability of the equipment in the production of stainless steel flat plates.

A threaded hole 2033 is opened at the midpoint of the driven pulley 2032. The driven pulley 2032 is rotatably connected to the drive pulley 2023 through the transmission belt 2034. Connecting screw 204: It is engaged in the threaded hole 2033. The bottom of the connecting screw 204 is fixedly connected to the connecting base plate 2041. The two ends of the bottom of the connecting base plate 2041 are fixedly connected to the connecting bracket 2042. The two sides of the connecting base plate 2041 are fixedly connected to the guide protrusion 2043. The guide protrusion 2043 is slidably installed in the limiting groove 2044 on the inner side wall of the connecting recess 202.

[0021] The starting motor 2021 drives the drive shaft 2022 to rotate, which in turn drives the drive pulley 2023 to rotate. The drive pulley 2023 drives the driven pulley 2032 to rotate via the transmission belt 2034. The driven pulley 2032 engages with the connecting screw 204 through the threaded hole 2033. The connecting screw 204 is fixed on the connecting base plate 2041, which in turn is guided and limited in the limiting groove 2044 by the guide protrusion 2043. As the driven pulley 2032 rotates, it drives the connecting screw 204 to adjust its height, thereby adjusting the connecting bracket 2042 and thus adjusting the spacing between the rolls.

[0022] Example 2: Based on Example 1, wherein... Figure 4 and Figure 5 As shown, a disassembly assembly 3 is provided between the connecting brackets 2042.
