Once the equipment is in place, it needs to be fixed to the foundation using anchor bolts. Anchor bolts must be installed to ensure reliable fastening to avoid loosening or displacement of the equipment during operation. Before bolting, the levelness of the equipment should be checked again to ensure that it is in the most installed state.
Connections to hydraulic systems
The hydraulic system is the core part of the hydraulic press, and its installation includes the connection of hydraulic pipelines and the installation of hydraulic pumps. When connecting hydraulic pipelines, the tightness of the pipelines should be ensured to avoid leakage of hydraulic oil. The installation of the hydraulic pump needs to be aligned with the electric motor to ensure its smooth operation. In addition, a hydraulic oil tank should be installed and injected with hydraulic oil that meets the requirements of the equipment.
Installation of electrical systems
The installation of the electrical system mainly includes the connection of power lines, the installation of the control cabinet and the arrangement of sensors. When connecting the power cord, you should ensure the correctness and safety of the wiring to avoid damage to the equipment caused by the wrong wiring. The control cabinet should be installed in such a way that it is easy to operate and that all electrical components are inspected to ensure that they are working properly. The arrangement of the sensors should be based on the operational needs of the equipment to ensure that it can accurately detect the operating status of the equipment.
Installation of lubrication systems
The installation of the lubrication system includes the connection of the lubricating oil line and the installation of the lubrication pump. The function of the lubrication system is to provide necessary lubrication for the moving parts of the equipment, reduce wear and improve the service life of the equipment. When installing the lubrication system, it is necessary to ensure the smooth flow of the lubricating oil pipeline, and check the oil supply of each lubrication point to ensure that the lubrication is sufficient.
Installation of safety devices
The safety devices of the hydraulic press include an emergency stop button, a safety shield, an overload protection device, etc. The installation of these devices must be carried out in strict accordance with the requirements of the equipment instructions to ensure that the equipment can respond to potential safety hazards in a timely manner during operation and protect the safety of operators.
Third, the debugging steps of the hydraulic press
After the installation is completed, the hydraulic press needs to be fully commissioned to ensure that the equipment can operate normally and achieve the expected production results. The commissioning process consists of steps such as preliminary inspection, no-load test run and load test run.
Preliminary examination
Before commissioning, the equipment should be thoroughly inspected to ensure that all installation steps have been completed and that there are no omissions or installation errors. The contents of the preliminary inspection include the oil level inspection of the hydraulic system, the wiring inspection of the electrical system, the oil supply inspection of the lubrication system, and the functional inspection of the safety device.
No-load test run
No-load test run refers to the test run of the four-column hydraulic press without loading the workpiece to check the basic functions of the equipment and the coordination of various systems. In the process of no-load test operation, it should be checked whether the pressure of the hydraulic system is stable, whether the movement of the hydraulic cylinder is stable, and whether the control of the electrical system is sensitive. If any abnormalities are found, the trial operation should be stopped immediately, and the equipment should be adjusted and repaired.
Load test run
After the no-load test run is qualified, the load test run is carried out. Load test run refers to the comprehensive testing of the equipment by simulating the actual production process with the workpiece loaded. During the load test operation, the working accuracy, pressure output, running speed, noise and vibration and other indicators of the equipment should be checked, and the equipment should be ensured to operate stably at full load.
Data logging and analysis
During the load test operation, the operating data of the equipment should be recorded, including pressure, temperature, speed, time and other parameters. Through the analysis of these data, it is possible to determine whether the operating status of the equipment meets the design requirements and whether further adjustment and optimization are required.
Equipment tuning and optimization
Based on the results of the data analysis of the trial run, the necessary adjustments and optimizations are made to the equipment. For example, adjusting the pressure setting of the hydraulic system, optimizing the oil supply of the lubrication system, correcting the control accuracy of the electrical system, etc. Through these adjustments, the work efficiency and production quality of the equipment can be improved, and the stable operation of the equipment can be ensured after it is put into production.
Final inspection and acceptance
After commissioning, a final inspection of the equipment should be carried out to ensure that all systems have met the design requirements and that the equipment is operating stably. After passing the final inspection, the acceptance of the equipment is carried out. Acceptance includes the verification of equipment performance, the confirmation of technical parameters and the handover of equipment documents. After passing the acceptance, the equipment can be put into formal production.
