Construction machinery forging dies usually need to use pneumatic and hydraulic systems to achieve the movement and locking of the die. The roles and components of these two systems are described below.
- Pneumatic system:
The pneumatic system mainly drives the movement of the mold through air pressure. It usually consists of the following main components:
- Compressed air source: Provides the required air source, usually produced by a compressor.
- Air filter device: used to filter impurities and moisture in the air to ensure air quality.
- Pressure regulator: controls and regulates the pressure of the air to meet the requirements of the mold operation.
- Pneumatic actuator: such as cylinder, pneumatic valve, etc., according to the control signal to control the movement of the mold, such as opening and closing, clamping, etc.
- Control elements: such as sensors, switches, etc., used to sense the mold state and control the work of the pneumatic system.
- Hydraulic system:
The hydraulic system mainly drives the movement of the mold through the pressure of the liquid. It usually consists of the following main components:
- Hydraulic pump station: provides the required hydraulic power, usually consisting of a hydraulic pump and an electric motor.
- Hydraulic tank: Store hydraulic oil and control the temperature of the hydraulic system through the cooling device.
- Hydraulic control valve: by controlling and adjusting the direction, pressure and flow of the liquid flow, to achieve the control of the mold operation.
- Hydraulic actuator: such as hydraulic cylinder, hydraulic motor, etc., converts hydraulic energy into mechanical energy to drive the action of the mold.
- Control components: such as hydraulic sensors, hydraulic control spool, etc., used to sense the mold status and control the work of the hydraulic system.
These two systems are usually selected and applied according to the specific mold needs and working conditions. The pneumatic system is easy to operate, suitable for small molds and simpler operations; The hydraulic system has a larger driving force and a wider range of applications, suitable for large molds and complex operations.
It should be noted that when using pneumatic and hydraulic systems, operation and maintenance should be carried out in strict accordance with relevant safety specifications, and various components of the system should be checked and maintained regularly to ensure the normal operation and safety of the system.
