Sheet bending machine as a basic machinery, its maintenance measures if done in place can improve the efficiency of the work of the sheet bending machine itself life. We will introduce the following is its maintenance content:
Filter.
- The filter should be replaced or cleaned thoroughly every time oil is changed.
- The air filter on the fuel tank should be checked and cleaned every 3 months, preferably 1 year.
- The machine tool has the related alarm or the oil quality is not clean and so on other filter is abnormal, should replace.
Hydraulic components.
- Monthly clean hydraulic components (substrates, valves, motors, pumps, tubing, etc.) , to prevent dirt into the system, not the use of cleaning agents.
- After a month of using the new machine, check the tubing bending deformation, if abnormal should be replaced. After using two months, should fasten the connection place of all fitting, should turn off when this work, the system has no pressure.
Hydraulic circuits.
- Weekly check the oil level of the tank, such as hydraulic system maintenance should also be checked, the oil level below the oil window should be filled with hydraulic oil.
- System oil temperature should be between 35 ° C ~ 60 ° C, not more than 70 ° C, if too high will lead to deterioration of oil and accessories damage.
- The hydraulic oil used in this machine is ISO HM46 or Mobil DTE25. Four. New machine work after 2000 hours should change oil, after each work 4000 ~ 6000 hours should change oil, each oil change, should clean the oil tank.
Common use of sheet bending machine fault treatment methods:
- understand the machinery and equipment operators, master the operation of machinery and equipment. The main Hydraulic drive system include: the work is not all normal, hydraulic oil pump is not abnormal.
- Look at the actual conditions of the Hydraulic drive system and see if there is a problem with the system software working pressure, speed, hydraulic fluid, leakage, vibration, etc. . Listen for Hydraulic drive system sounds, such as pounding.
- The simple fault detection method is the most popular method at this stage, which is based on the work experience of the maintenance staff. Using a simple instrument panel based on the Hydraulic drive system of common failures.
- Objectively select and ask, see, listen, touch, smell and other ways to grasp the work of the sheet bending machine, analysis, diagnosis, clear cause of common faults and location.
- Hydraulic Drive system analysis is a common method used by project professionals at this stage. It requires that you have a basic knowledge of the hydraulic press and can read the Hydraulic drive system. We must master the names and functions of the components represented by the graphic symbols, as well as the basic principles, structures and characteristics of the components.
- Gear oil inspection cleanliness of the time and results. Filter cleaning and removal of the status of common fault before it is not carried out on the hydraulic adjustment.
- The schematic diagram of the Hydraulic drive system circuit of the Bender analyzes the common faults of the hydraulic control system, finds out the locations and causes of the common faults, and puts forward the methods of fault detection.
- Bending machine has a basic fusion posture cycle system table, comparative analysis, identification of common fault is very easy. Therefore, to study the basic knowledge of hydraulic press and grasp the hydraulic schematic diagram is a powerful assistant for fault detection and cleaning, and is the basis of other common fault analysis methods.
- Whether or not the hermetic components have been replaced. Before and after the common fault Bender left and right what abnormal situation has occurred. In the past, what common failures have occurred in the system software and how to clean them need to be mastered one by one.
- Pump noise and abnormal sound. To tell if a Hydraulic drive system is working properly. Feel the temperature, vibration, crawling movement and the level of tightness at the joints, to determine whether the working attitude of fitness movement components is all normal.
