Hydraulic Press Machines: Power, Performance, and Precision
The power, performance and precision of hydraulic press machines are their important technical indicators. Following is a detailed introduction to them:
● Power of hydraulic presses
Power source: The power of hydraulic presses mainly comes from the hydraulic system. The motor drives the hydraulic pump, converting mechanical energy into hydraulic energy, so that the hydraulic oil generates pressure and flow in the system. The hydraulic oil is transported to actuators such as hydraulic cylinders through pipelines and various control valves, pushing the piston and other components to move, thereby generating pressure and force to achieve operations such as processing of workpieces.
Determinants of power size
System pressure: System pressure is one of the key factors that determine the power of hydraulic presses. Generally speaking, the higher the pressure, the greater the power that the hydraulic press can generate. For example, the working pressure of some large forging hydraulic presses can be as high as hundreds of MPa, which can generate thousands of tons or even tens of thousands of tons of pressure. Hydraulic cylinder size: The larger the inner diameter and piston area of the hydraulic cylinder, the greater the thrust that can be generated under the same pressure. For example, under the same pressure, a hydraulic cylinder with an inner diameter of 200 mm generates much greater thrust than a hydraulic cylinder with an inner diameter of 100 mm.
Hydraulic Press Machines: Power, Performance, and Precision
● Performance of hydraulic press
Working speed: The working speed of hydraulic press includes no-load fast down speed, working feed speed and return speed. No-load fast down speed can improve work efficiency and reduce auxiliary time; working feed speed is adjusted according to different processing requirements to ensure processing quality; return speed is generally required to be fast so as to complete a working cycle as soon as possible.
Pressure stability: The hydraulic press needs to maintain a stable pressure output during operation to ensure the consistency of processing quality. Excessive pressure fluctuations can lead to problems such as unstable workpiece processing size and poor surface quality. Advanced hydraulic presses usually use high-precision pressure control systems that can control pressure fluctuations within a small range.
Reliability: The reliability of hydraulic presses is reflected in their ability to operate stably for a long time and rarely fail. This is closely related to the design, manufacturing quality and selection of key components of the hydraulic system. For example, the use of high-quality hydraulic pumps, hydraulic cylinders, seals, etc. can improve the reliability and service life of hydraulic presses.
Operability: Good operability is an important manifestation of the performance of hydraulic presses. Including whether the operation interface is concise and clear, whether the layout of the control buttons is reasonable, whether there are multiple operation modes (such as manual, semi-automatic, fully automatic), etc., so that operators can operate flexibly according to different work requirements.
● Accuracy of hydraulic press
Position accuracy
Slider positioning accuracy: The slider is the main component of the hydraulic press to perform pressure processing, and its positioning accuracy directly affects the processing size accuracy of the workpiece. Generally speaking, the positioning accuracy of the slider of a high-precision hydraulic press can be controlled within ±0.01 mm.
Workbench flatness: The flatness of the workbench also has an important impact on the processing accuracy of the workpiece. If the flatness of the workbench is out of tolerance, it will cause uneven force on the workpiece during processing, thereby affecting the processing accuracy. Usually, the workbench flatness requirement is not more than ±0.05 mm per meter of length.
Pressure accuracy
Pressure control accuracy: The pressure control accuracy of the hydraulic press determines the accuracy of the pressure applied to the workpiece. Through high-precision pressure sensors and advanced control systems, the pressure control accuracy of the hydraulic press can reach ±1% FS (full scale) or even higher.
Pressure uniformity: On the workbench of the hydraulic press, the pressure uniformity at different positions is also important. If the pressure is uneven, the workpiece will be deformed and uneven in thickness during processing. Generally, the pressure uniformity of the hydraulic press work surface is required to be within ±5%.
The power, performance and precision of the hydraulic press are interrelated and affect each other, and jointly determine the processing capacity and processing quality of the hydraulic press. In practical applications, it is necessary to reasonably select and adjust the various parameters of the hydraulic press machine according to the specific processing needs and process requirements to achieve the best working effect.
