Maintenance Tips for Deep Drawing Hydraulic Presses
Maintenance of the deep drawing hydraulic press is crucial. Following are some maintenance tips for deep drawing hydraulic press.
1. Daily maintenance
● Cleaning work
After each use, the work surface, mold and body of the stretching hydraulic press should be cleaned in time. Because during the stretching process, impurities such as metal debris and oil stains may remain. For example, when stretching metal sheets, the debris on the cutting edge is easy to fall on the workbench. If it is not cleaned, it may scratch the mold or affect the accuracy of the next stretching. You can use a clean rag to wipe the workbench and mold. For oil stains that are difficult to remove, you can use a special metal cleaning agent. Clean the cooling system of the hydraulic press regularly. If it is a water-cooled hydraulic press, impurities in the water may scale in the cooling pipe, affecting the heat dissipation effect. Generally, check the water quality in the cooling water tank every once in a while (such as one month), replace the cooling water if necessary, and clean the water tank and pipes.
● Check the hydraulic oil
Before starting the machine every day, check the oil level of the hydraulic oil. Insufficient hydraulic oil will cause unstable pressure in the hydraulic system and affect the stretching effect. The oil level can be checked by the oil level gauge on the hydraulic oil tank, and the oil level should be kept within the specified range of the oil level gauge.
Check the quality of hydraulic oil regularly (such as every three months). During long-term use, hydraulic oil may be contaminated and mixed with water, impurities, etc. The quality of hydraulic oil can be judged by testing its viscosity, acid value and other indicators. If the quality of hydraulic oil deteriorates, it should be replaced in time.
● Check the connection of each component
Check whether the pipeline connection of the hydraulic press is tight. Because the pressure in the pipeline is high when the hydraulic system is working, if the pipeline joint is loose, it may cause hydraulic oil leakage. You can preliminarily judge whether there is leakage by observing whether there is oil stain at the pipeline joint, and tighten the joint appropriately with a wrench.
Check whether the mold is installed firmly. During the stretching process, the mold is subjected to a large force. If it is not installed firmly, it may cause the mold to shift and affect the product quality. After each mold replacement, carefully check whether the fixing bolts of the mold are tightened.

2. Regular maintenance (monthly or quarterly)
● Hydraulic system maintenance
Check the working condition of the hydraulic pump. The hydraulic pump is the core component of the hydraulic system. Listen to whether the sound when it is working is normal. If there is abnormal noise, it may be that the internal parts of the pump are worn or air is inhaled. At the same time, check whether the seal of the hydraulic pump is intact to prevent hydraulic oil leakage.
Clean or replace the filter of the hydraulic system. The filter can filter impurities in the hydraulic oil to prevent it from entering the hydraulic components and causing damage. As the use time increases, the filter will gradually become clogged. Generally, the filter should be cleaned or replaced every certain period of time (depending on the working environment and frequency, such as 1-3 months).
● Electrical system maintenance
Check the electrical components in the electrical control cabinet. Check whether the wiring of components such as contactors and relays is loose and whether the contacts are good. Because during the operation of the hydraulic press, the electrical system will frequently operate, which may easily lead to loose wiring. At the same time, clean the dust in the electrical control cabinet. Excessive dust accumulation may cause faults such as short circuits. Check the operation of the motor. Including the temperature and speed of the motor. If the motor temperature is too high, it may be that the motor is overloaded or the heat dissipation is poor. The temperature can be monitored by the temperature sensor installed on the motor. The motor temperature should be within the specified range during normal operation.
3. Long-term maintenance (every year or longer)
● Mechanical component maintenance
Check the body structure of the stretching hydraulic press. Check whether the body is deformed, cracked, etc. Especially for the parts that are subjected to large tensile forces for a long time, it is necessary to focus on the inspection. If there is a problem with the fuselage, repair or replace the parts in time to ensure the safety performance of the hydraulic press.
Check and adjust the accuracy of the guide rail. The guide rail has a great influence on the movement accuracy of the mold. As the use time increases, the guide rail may wear, resulting in unsmooth movement of the mold. Tools such as level gauges can be used to check the levelness and straightness of the guide rail and make appropriate adjustments.
● Comprehensive system inspection
Ask professional maintenance personnel to conduct a comprehensive inspection and calibration of the hydraulic press. Including pressure calibration of the hydraulic system, parameter adjustment of the electrical system, etc. Generally, a comprehensive inspection is carried out at least once a year to ensure that the performance of the hydraulic press meets the requirements. At the same time, according to the inspection results, the vulnerable parts of the hydraulic press can be replaced in advance to avoid sudden failures.
