Hydraulic press is a commonly used metal stamping equipment, widely used in metal manufacturing industry. It uses the high-pressure liquid pressure generated by the oil pressure system to drive the punch through the cylinder for stamping processing. Below I will introduce some techniques for the use of hydraulic press from the aspects of equipment operation, safety precautions, troubleshooting, etc.
1. Equipment operation
1. Check before starting: Before using the hydraulic press, check whether the operation buttons and handwheels of the equipment are normal, whether the pressure of the hydraulic system is stable, and ensure that the surrounding environment of the equipment is clean and free of debris.
2. Workpiece fixing: Before stamping, the workpiece to be stamped should be fixed on the workbench to ensure its accurate position and avoid deviation, sliding and other situations during processing.
3. Die installation: Select the appropriate die and install it correctly on the equipment according to the process requirements to ensure the appropriate stroke and accurate stroke.
4. Adjust the opening: Adjust the opening of the equipment according to the thickness of the workpiece and the required processing depth, so that the process requirements can be met during the stamping process.
5. Installation guide rail: For larger size workpieces, it may be necessary to install guide rails during the stamping process to ensure the smooth movement of the workpiece during processing.
6. Adjusting punch: The equipment is equipped with a handwheel or button to adjust the depth and position of the punch, which can be adjusted according to the process requirements.
7. Determine the number of stamping: according to the process requirements and the material of the workpiece, determine the number of stamping to ensure the required processing effect.
8. Processing operation: According to the operation instructions of the equipment, the workpiece is placed on the workbench, the punching press is started, and the processing is carried out according to the process requirements.
9. Flushing waste cleaning: timely cleaning of the waste generated in the punching press to maintain the normal operation of the equipment and the cleanliness of the working environment.
2. Safety precautions
1. Wear protective equipment: When operating the hydraulic press, wear safety gloves, goggles, work clothes and other protective equipment to prevent injury.
2. Safety operation button: The equipment is equipped with emergency stop button and two-hand button and other safety devices, should pay attention to use during operation to ensure safety.
3. Ensure that the die is firm: in the process of processing, ensure that the die is firmly installed to avoid the situation of the die falling off or offset.
4. Pay attention to the positioning of the workpiece: the correct positioning of the workpiece is crucial to the processing results, and it is necessary to ensure that the workpiece is accurately fixed on the workbench to avoid deviation.
5. Do not exceed the load: according to the rated load and process requirements of the equipment, do not exceed the restrictions of the equipment to avoid accidents.
6. Pay attention to the operating status of the equipment: During the operation, always pay attention to the operating status of the equipment, such as abnormal noise, vibration and other abnormal situations, stop the inspection in time.
7. Avoid hand contact: When the punch is operated, the hand should be far away from the punch and the workpiece to avoid clamping injuries.
8. It is strictly prohibited to disassemble the equipment without authorization and professional guidance, so as not to cause safety accidents.
Three, troubleshooting
1. Equipment shutdown: If equipment shutdown occurs, first check whether the power supply is normal and whether there is an abnormal blinking alarm indicator.
2. Poor stamping: If the quality of the stamping workpiece is poor, check whether the state of the die and punch is normal, and ensure that the stroke and stroke are set correctly.
3. Hydraulic system problem: If the pressure of the hydraulic system is found to be unstable or unable to produce high pressure liquid pressure, it is necessary to check whether the oil pump and oil pipe line are leaking or blocked.
4. Protection device failure: If the safety protection device fails or is abnormal, it should be stopped immediately for inspection, and seek the help of professionals to repair.
In SUMMARY:
It is very important to master the using skills of hydraulic press to improve work efficiency and safe production. Through reasonable operation of the equipment, attention to safety matters, timely troubleshooting, can effectively ensure the normal operation of the equipment, and improve the punching machine processing quality and efficiency.
