& nbsp; Leveling machine, also known as leveling machine, flatbed machine, straightening machine, straightening machine. The most formal name is the board leveling machine, but the common people like to call it the leveling machine because they are used to it. The leveling machine is mainly used to correct various specifications of boards and cut them into blocks. This function is suitable for leveling various cold and hot rolled plates. Due to its convenient and simple operation, it is widely used in various 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, it has become an indispensable and essential product in production. There are many forms of mechanisms for leveling machines, and this structure is relatively reasonable. The designed leveling machine is solid, and the supporting rollers on the leveling rollers can effectively support the leveling rollers. The crossbeam is relatively large and will not deform. There are also springs pulled on the crossbeam to eliminate the gap between the beams on the leveling machine.  & 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.
