HENGLI high-strength metal sheet 3 in 1 feeder is specially designed for the automatic feeding of the medium-thickness sheet with high yield strength in punching. It is a new type of unwinding and leveling servo feeding machine. The clamping wheel face adopts plow low-blasting plating to hard chrome plating. The treatment effectively increases the friction between the material and the roller to ensure that no slippage occurs in the servo feeding process, so as to achieve high accuracy of feeding, and the outlet is equipped with a new type of oil coating device to maximize the surface coating of the material. The oil coating is evenly applied to effectively protect the service life of the mold. The discharge port increases the material rotation mechanism, effectively improves the utilization rate of the site, and realizes high plate arc and feeding capacity. The equipment adopts Japanese servo system, pneumatic components, bearings and electrical appliances. Components, control systems use large-size touch screens, high-capacity user product parameter information memory function, and a complete equipment failure alarm system, making the machine longer life, higher work efficiency, and more reliable safety factor.
