4 roller rolling machine

Product Description

4 roller rolling machine is a specialized equipment in metal processing and manufacturing process, used to roll metal plates into cylindrical or conical shape.

• Basic structure: 4 roller rolling machine consists of four main rolls, including a top roll (upper roll), two bottom rolls (lower roll) and two side rolls (support roll). These rolls are controlled by a hydraulic system to precisely regulate pressure and bending parameters. In addition, the machine includes a control panel to operate the movement of the rolls and to adjust the bending parameters.
• Principle of operation: When the sheet metal is fed into the drum, the motorized upper roll adjusts its height and applies pressure to the sheet metal to produce the bend. At the same time, the side rolls, working alone or in synchronization with the upper roll, provide additional support and guide the bending and forming of the sheet.

Advantages of 4 roller rolling machine system

Precise control:The hydraulic system of a four-roll mill uses precision sensors and valves to fine-tune the rolls, ensuring accurate and consistent workpiece dimensions.

Autonomous driving:The computer controls the hydraulic system, sets the rolling program and changes the parameters. This automates the entire production process, from loading materials to loading and unloading finished products.

Stability:The damping and pressure control of the hydraulic system of the 4 roller rolling machine keeps the rolling force constant even if the thickness of the sheet changes during the rolling process.

Power regulation:The hydraulic system of the 4 roller rolling machine has a multi-cylinder rolling machine, which allows the operator to choose the optimal rolling force according to the material characteristics and reduce the elastic deformation of the material.

Quick response:The hydraulic system has a fast charge-discharge path, which allows the cylinder to quickly reach the target position or pressure according to the command.

Security features:The hydraulic system includes a mechanical brake, stabilizer valve, emergency stop and safety monitor for instant shutdown when necessary.

Easy maintenance:The modular design of the hydraulic components facilitates quick replacement and repair. Monitoring of liquid cleanliness and oil quality also facilitates routine maintenance

Environmental adaptability:The hydraulic system is well sealed and can generally operate in harsh conditions such as dust and humidity, minimizing the environmental impact of the equipment.

Energy saving features:The hydraulic system of the 4 roller rolling machine is manufactured to the highest standard, using energy recovery and efficient components to reduce energy consumption and promote green production.

Improved lateral roll stability:The integrated design of the CIOC® system improves precision and layer alignment during the winding process by reducing lateral rolling vibration and deviation.

The 4 roller rolling machine is equipped with hydraulic system to ensure high efficiency and efficiency. The system allows high-precision cooling. The cooler is also automatic, stable, safe and energy-saving. These features ensure efficient operation and long-term reliability in many industrial applications.
