& nbsp;& nbsp; Leveling machine is a commonly used equipment in sheet metal processing, and the shaping of the leveling machine mainly depends on the thickness, material, and requirements of the calibrated strip. The thicker the material, the better the required structural rigidity, the fewer rollers, the larger the roller diameter, and the higher the power, and vice versa. The unwinding and leveling machine is an automated processing equipment that processes coils of a certain width into the required fixed length dimensions through the process of unwinding, pulling, leveling, cross cutting, conveying, and stacking. This device is centrally controlled and operated by a display screen, with a high degree of automation and production efficiency One roll can achieve the desired finished product in one feeding, effectively reducing the labor intensity of workers. & nbsp; The application scope of leveling machines covers multiple industries such as machinery, metallurgy, building materials, chemical industry, electronics, power, and light industry. Especially in industries such as shipbuilding, locomotives, boilers, bridges, and metal structure factories, they have become indispensable products in production. According to the safety protection requirements of leveling machines, leveling machine protective devices can be selected and used, including fixed protective devices, movable protective devices, adjustable protective devices, and interlocking protective devices. It is also possible to configure unwinding and feeding in front of the machine, followed by cutting, stacking, and online mechanisms. Through the control system, a fully functional production line can be connected to level and cut metal coils. According to the joint of the tested meter, the present utility model achieves thermal protection for the rear stop stroke adjustment motor by setting the parameters of the frequency converter. The leveling machine avoids impurities from corroding the cutting tool or cutting blank, thereby ensuring the quality of the surface and hardness metallographic structure of the cutting tool or cutting blank, and avoiding contamination by cooling oil. The specific configuration of the equipment can be determined according to customer requirements for the number of leveling machine rollers and weight.
