As the main equipment for transporting rolled pieces, the structural design and optimization of roller tables for strip mills and rolling mills are crucial to improving the conveying stability of mechanical parts. The roller table ensures the smooth, accurate and efficient conveying of rolled pieces through its unique structure and function.
1. Basic structure and composition of roller table
The roller table is mainly composed of guide plates, guard plates and several rollers, as well as multiple motors and their transmission shafts and reducers. The rollers are generally made of seamless steel pipes, and are also made of cast iron pipes or other materials. The roller shaft is fixed in the bracket. The roller table is a transportation equipment that uses the rotation of cylindrical rollers to transport rolled pieces. It connects the various processes of the rolling production process to each other, realizes mechanized operation, greatly improves working conditions, improves production efficiency, and provides conditions for realizing automated operation.
2. The influence of roller table structure on conveying stability
The design and layout of rollers: The diameter, length and material selection of rollers have a direct impact on conveying stability. Reasonable roller design can reduce the friction and resistance of rolled pieces during transportation and ensure smooth operation of rolled pieces. The arrangement of rollers is also a key factor. On the hot strip mill, the rollers are divided into several sections, and each section of the roller conveys rolled pieces at an independent or synchronous speed and direction with the rollers. This arrangement helps to reduce the impact and vibration of rolled pieces during transportation and improve transportation stability.
The role of guides and guards: Guides and guards are used to guide and protect the path of rolled pieces during transportation. They can prevent rolled pieces from deviating from the predetermined track and ensure stable operation of rolled pieces on the rollers. The design of guides and guards also takes into account the size and shape of rolled pieces to ensure that the gap between them and the rolled pieces is appropriate to reduce friction and resistance.
Optimization of motors and transmission systems: The performance of motors and transmission systems directly affects the running speed and stability of rollers. The use of high-performance motors and transmission systems can ensure that the rollers run at a constant speed and reduce speed fluctuations and vibrations. The optimization of the transmission system also includes selecting the appropriate transmission ratio and reducer type to ensure that the rollers have sufficient torque and power reserves during transportation.
Application of roller centering device: In order to enable the rolled product to run in the center of the roller, a drum roller is used, and the horizontal planes on the left and right sides are slightly tilted alternately, or the angle between the axis of the roller and the running direction of the rolled product is alternately slightly tilted from the right angle. This centering device can reduce the deviation and swing of the rolled product during transportation and improve the transportation stability.
3. Optimization and improvement of roller structure
Adjustment of roller spacing: According to the size and shape of the rolled product, the roller spacing is reasonably adjusted to ensure that the rolled product is fully supported and guided during transportation.
Treatment of roller surface: Special treatment is performed on the roller surface, such as spraying wear-resistant materials or hardening treatment, to improve the wear resistance and service life of the roller.
Upgrade of transmission system: Use advanced transmission technology and equipment, such as replacing the collective transmission mode with a single transmission mode, to improve the running accuracy and stability of the roller.
Application of intelligent monitoring system: Introduce an intelligent monitoring system to monitor the running status of the roller and the transportation of the rolled product in real time. Through data analysis and early warning functions, potential problems can be discovered and handled in a timely manner to ensure the stable operation of the roller.
In summary, the structural design and optimization of mechanical components roller tables for strip mills and rolling mills are of great significance to improving the conveying stability of mechanical components. The conveying stability and efficiency of roller tables can be significantly improved through reasonable roller design and layout, the role of guide plates and guard plates, the optimization of motors and transmission systems, and the application of roller table centering devices.
