Cut to Length Line Used for Leveling&Cutting Coils Into Required Length
In industrial equipment, nitrogen accelerated shearing machine usually refers to metal sheet processing equipment that uses nitrogen gas accumulator as a power assist or balancing system. The following is a detailed description of its working principle, application and precautions:
1. Principle of nitrogen acceleration system
Function of nitrogen accumulator:
In hydraulic shearing machine, nitrogen accumulator stores energy by compressing nitrogen and releases it quickly when needed to achieve the following functions:
Accelerate the movement of the tool holder: improve shearing efficiency and reduce idle time.
Balance the weight of the tool holder: reduce the load of the main motor and extend the life of the equipment.
Buffer the impact force: reduce vibration during shearing and protect the mechanical structure.
Why use nitrogen?
Nitrogen has stable chemical properties (not easy to ignite and explode), non-oxidizing, suitable for high-pressure environment, and lower cost than other inert gases.
2. Application of Kaiping shearing machine
Kaiping line (coil Kaiping shearing production line):
Nitrogen acceleration system is often used in Kaiping shearing machine with continuous operation, and is used with uncoiler and leveler to achieve efficient cutting of metal coils (such as steel plates and aluminum plates).
Advantages:
Faster shearing speed (especially for thick plates).
Energy saving (reducing the continuous working pressure of the main pump).
3. Equipment composition and key components
Nitrogen accumulator stores high-pressure nitrogen and provides instantaneous power.
Hydraulic system Main drive system, coordinated with nitrogen to control the movement of the tool holder.
Shearing tool holder performs cutting action, and nitrogen assists its rapid return.
Electrical control system adjusts the nitrogen release pressure and timing.
4. Precautions for use and maintenance
Nitrogen filling pressure:
It must be filled strictly according to the requirements of the equipment manual (usually 10~15MPa). Too high or too low pressure will affect performance.
Sealing inspection:
Check the accumulator seal regularly to prevent nitrogen leakage (leakage will cause acceleration failure).
Safe operation:
The pressure in the accumulator must be released before maintenance.
Avoid direct exposure or impact of nitrogen cylinders.
Common faults:
Slow movement of the tool holder: may be due to insufficient nitrogen or hydraulic oil contamination.
Large shear vibration: accumulator pressure imbalance or hydraulic valve jam.
