1. Basic principles and composition of the hydraulic system
The hydraulic system is mainly composed of key components such as the oil tank, pump, cylinder and control valve. These components work together to pump the hydraulic oil from the oil tank and flow it to the cylinder after being pressurized by the pump, thereby generating the required pressure. The control valve is responsible for regulating the flow direction and speed of the oil to ensure that the hydraulic system can operate accurately according to the operator's instructions.
2. How to achieve smooth pressure
High-quality hydraulic oil: Using high-quality hydraulic oil can reduce impurities and bubbles in the oil, thereby reducing friction and wear of the hydraulic system and improving the stability and durability of the system.
Precise flow control: By adjusting the displacement of the pump or using a proportional flow valve, the flow of hydraulic oil can be accurately controlled to ensure that the hydraulic system can provide stable pressure during operation.
Adjustment of the pressure regulating valve: The pressure regulating valve is a key component used to adjust the pressure in the hydraulic system. By adjusting the set value of the pressure regulating valve, the output pressure of the hydraulic system can be accurately controlled to meet the needs of the bending process.
Application of accumulator: The accumulator can store and release energy, thereby stabilizing the pressure fluctuations in the hydraulic system. During the bending process, the accumulator can absorb and release the instantaneous pressure changes caused by the deformation of the workpiece, so that the hydraulic system can maintain stable operation.
Advanced control system: The hydraulic sheet bending machine is usually equipped with advanced control systems, such as PLC programmable controllers. These systems can monitor the operating status of the hydraulic system in real time and adjust the pump displacement, control valve opening and other parameters as needed to ensure that the hydraulic system can provide stable pressure.
Cooling and filtration of oil: The hydraulic system will generate heat and impurities during operation. In order to ensure the stability and durability of the system, coolers and filters are required to cool and filter the oil. This helps to reduce the temperature of the oil and reduce the impurity content, thereby improving the performance and stability of the hydraulic system.
3. The impact of stable pressure on the bending process
Steady pressure is crucial to the bending process of the hydraulic sheet bending machine. It not only ensures the stability and consistency of the bending process, but also improves the precision and quality of the product. At the same time, stable pressure also helps to extend the service life of the hydraulic system and reduce maintenance costs.
The hydraulic system of the hydraulic sheet bending machine provides stable pressure through high-quality hydraulic oil, precise flow control, pressure regulating valve adjustment, accumulator application, advanced control system, oil cooling and filtration, etc. These measures together ensure the stability and consistency of the bending process and improve the precision and quality of the products.
