Four-High Precision Leveler or say, leveling machine
A four-high precision leveler, also known as a four-roll leveler, is an advanced piece of equipment to flatten metal sheets or plates. This machine is crucial in industries where high-quality flatness and surface finish are essential. The leveling machine is a special equipment for leveling metal plates used for rolling uneven plates (carbon plates, stainless steel plates, aluminum plates, other metal plates)at normal temperature. It can be combined according to the relevant configuration requirements to form uncoiling, leveling, shearing, and other plate product lines. It suits machinery, vehicles, metal products, household appliances, steel structures, decoration, and other industries.
Here is an overview of its components, working principle, and key features:
Components
1. **Work Rolls**: Four rolls arranged in a two-over-two configuration, providing precise flattening.
2. **Backup Rolls**: Support the work rolls to maintain their shape and prevent deflection.
3. **Drive System**: Powers the rolls to move the metal sheet through the machine.
4. **Hydraulic System**: Adjust the position of the rolls to achieve the desired flatness.
5. **Control System**: Includes a PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) for precise control and monitoring.
Working Principle
1. **Feeding**: The metal sheet is fed into the leveler.
2. **Flattening**: The work rolls apply pressure to the sheet, bending it slightly to remove any internal stresses and achieve flatness.
3. **Support**: The backup rolls provide additional support to the work rolls, ensuring they remain in the correct position and maintain their shape.
4. **Adjustment**: The hydraulic system allows for fine adjustments to the position and pressure of the rolls to achieve the desired level of flatness.
Key Features
1. **High Precision**: The four-roll configuration provides excellent control over the flattening process, ensuring high-quality results.
2. **Adjustability**: The hydraulic system allows precise adjustments to accommodate different materials and thicknesses.
3. **Consistency**: The backup rolls ensure that the work rolls maintain their shape and position, resulting in consistent flatness across the entire sheet.
4. **Automation**: Advanced control systems enable automated operation, reducing the need for manual intervention and increasing efficiency.
Applications
The four-high precision leveler is widely used in automotive, aerospace, construction, and manufacturing industries, where high-quality flat metal sheets are required. It is particularly useful for materials that require precise flatness and surface finish, such as aluminum, stainless steel, and other high-strength alloys.
Summary
The four-high-precision leveler is an essential machine in the metal processing industry. It offers high precision, adjustability, consistency, and automation. Its advanced design and control systems ensure that metal sheets are flattened to the highest standards, making it indispensable in applications with paramount quality and accuracy.

slitting and recoiling line for medium plates
Feature of this laser blanking line
The production line is a general-purpose high-grade coil laser blanking processing equipment, which is suitable for blanking
of various blank sheets in automotive, hardware, and other industries, and can greatly improve the production efficiency and
material utilization rate of sheets to meet the large-scale production needs of modern enterprises.
Feature Of Cut-to-length line
The cut-to-length line is a special equipment for flattening thin metal coils and cutting them into blocks. It is usually composed of a loading cart, decompiler, plate supporting, pressing and drawing device, main leveling machine, movable bridges, guiding and correcting device, measuring mechanism, lamination device, shearing machine, conveying table, pneumatic discharge rack, hydraulic lifting and stacking table, conveying roller table and hydraulic system, electrical control system, etc. The cut-to-length line is controlled by PLC. The main hydraulic, pneumatic, and electronic control components, measuring
system are selected international well-known brands.
This production line is mainly used to process cold-rolled carbon steel coil, stainless steel coil, and non-ferrous metal coil plates. If equipped with a six-high structured leveling machine, it can flatten and cut coil plates with high surface requirements, such as metal and aluminum.
The production line can have primary or fine-leveling machines according to customer requirements. The fixed length and shear feeding machinery can adopt common mechanical appliances, cooperative action, and digital frequency conversion or AC servo technology. The shearing machines can be ordinary mechanical shearing machines, ordinary hydraulic shearing machines, high-speed brake shearing machines with an electromagnetic clutch, pneumatic clutch transmission power, movable shearing machines, and rotary flying shearing machines. After the production line is equipped with related forming machine tools, it can have a wider range of functional extensions.
