& nbsp; The leveling machine has a reasonable layout, easy operation, high degree of automation, high production efficiency, high work accuracy, and moderate price. It can process various cold-rolled, hot-rolled coils, silicon steel plates, stainless steel plates, color plates, aluminum plates, as well as various metal plates after electroplating or coating. Widely used in metal sheet processing industries such as automobiles, agricultural vehicles, containers, household appliances, packaging, and building materials. This production line is mainly used for feeding carts, single and double support unwinding machines, longitudinal cutting machines, trimming machines, shearing machines, stacking devices, etc. It is also equipped with swinging intermediate bridges, traction devices, correction devices, CNC feeding and sizing devices, etc. between each machine. This production line is an automatic coil processing equipment that integrates machinery, electricity, liquid, and gas.  & nbsp; The leveling machine is equipped with an upper pressing die and a lower pressing die, where the upper pressing die is fixed to the push rod of the hydraulic cylinder, and the cylinder body of the hydraulic cylinder is fixed to the support frame. Independent cooling water circuits are set inside the upper and lower pressing dies, and the outlet and inlet of the cooling water circuit are located above the upper or lower pressing die, respectively. The ratio of the radius/center distance of at least the first 5 rollers starting from the entrance of the leveling machine is the same as that of the traditional leveling machine, and the ratio of the radius/center distance of at least the last 5 rollers starting from the entrance of the leveling machine is similar to that of the curling elimination machine. The advantage is that the center distance between the middle rollers of the leveling machine increases. It can prevent impurities from corroding the cutting tool or cutting blank while rapidly quenching and cooling, thereby ensuring the quality of the surface and hardness metallographic structure of the cutting tool or cutting blank, and avoiding contamination by cooling oil.
