Fault 1: the air duct production line equipment does not lift the knife when punching the small mouth
Analysis: the solenoid valve may be blocked by sundries
Handling: check whether the solenoid valve is powered on, and check whether the hydraulic oil in the oil tank has been replaced on schedule under power on condition. The hydraulic oil needs to be replaced regularly. If there are sundries or the valve is not replaced for a long time, it is easy to block the valve or block the valve. Contact the after-sales service department of VIP machinery in time.
Fault 2: punching die and plate cutter of air duct production line cannot operate
Analysis:
1. It may be that the connection wire of the electric box control hydraulic solenoid valve is broken;
2. Maybe the relay in the middle of the electrical box is damaged;
3. The touch screen automatic processing page displays the status of no punching or stuck solenoid valve.
Handling: check whether the electrical circuit or equipment of the machine is damaged, replace and repair in time, and contact the after-sales service department of VIP machinery.
Fault 3: after the air duct production line equipment starts production, the size of the sheet metal is not stable or the sheet metal only goes on and on
Analysis:
1. The position of encoder status switch in the lower right corner of the touch screen is valid;
2. Encoder installed at one end of measuring wheel is loose, slipping or broken;
3. Encoder is damaged or signal wire is broken.
Handling: check the encoder and signal line to see if there is any deviation or damage, repair and replace in time and contact the after-sales service department of VIP machinery.
Fault 4: emergency stop and servo alarm of touch screen display system of air duct production line equipment flash
Analysis: the emergency stop button beside the touch screen is not loose, the servo motor has foreign body Kara, or the servo motor circuit is unstable
Handling: release the emergency stop button beside the touch screen, check whether the servo motor running track and guide rail are in Kara condition, check whether the servo motor connecting line is broken or loose, and contact the after-sales service department of VIP machinery in time.
Fault 5: the products produced by the air duct production line have cracks and scratches
Analysis: it may be that the raw materials of the product are unqualified or the production process has problems, and the machine parts have foreign matters.
Handling: check whether the raw materials are qualified and whether the operator carelessly brings the sharp foreign matters into the leveling rod.
Other minor faults:
1. The touch screen displays the hydraulic overload alarm and flashes
Solution: check whether the system pressure of the hydraulic station of the air duct production line is too high, whether the oil temperature is too high, whether the oil pump is damaged and causes the thermal relay to trip, disassemble the cover plate of the electrical box, and manually reset the thermal relay.
2. The uncoiler does not stop or discharge materials.
Solution: check whether the photoelectric switch for material inspection of the material support of the air duct production line is damaged or the connecting line is disconnected. Whether the feeding induction switch is placed correctly. The time relay in the uncoiler box is damaged. Check and replace it.
