Matters needing attention when using the air duct pipe product pipeion line and solutions to faults
The normal operation and operation of the air duct pipe product pipeion line are inseparable from the normal operation of the machine. Therefore, in order to ensure the normal operation of the machine and ensure that the daily air duct pipe product pipeion does not fail and stop, it is necessary to maintain and maintain the air duct pipe product pipeion machine. For the maintenance of the air duct pipe product pipeion line, it is necessary to proceed from all aspects. Before using the air duct pipe product pipeion line, you should read the instruction manual and other relevant information carefully to operate the air duct pipe product pipeion line correctly, and pay attention to the following points:
(1) The machine tool operators and maintenance personnel must be professionals who have mastered the corresponding machine tool professional knowledge or technically trained personnel, and must operate the machine tools in accordance with the safety operation regulations and safety operation regulations;
(2) Non-professionals are not allowed to open the electric cabinet door. Before opening the electric cabinet door, it must be confirmed that the main power switch of the machine tool has been turned off. Only professional maintenance personnel are allowed to open the door of the electric cabinet and conduct pipe power-on maintenance;
(3) Except for some parameters that users can use and can change, other system parameters, spindle parameters, servo parameters, etc., users cannot modify privately, otherwise it will bring equipment, workpiece, personal and other injuries to the operator;
(4) After modifying the parameters, when the first processing is performed, the machine tool is to be tested with no load by means of machine lock, single block, etc. without loading raw materials, and the raw materials are used for product pipeion after confirming that the machine tool is normal;
(5) The PLC program of the machine tool is designed by Primapress Machinery according to the needs of the machine tool and does not need to be modified. Incorrect modification and operation of the machine tool may cause damage to the machine tool and even harm the operator;
(6) If the continuous running time of the machine is too long, it will affect the life of the electrical system and some mechanical components, which will affect the accuracy of the machine tool. It is recommended that the continuous working time should not exceed 8 hours;
(7) All connectors, joints, etc. of the Primapress air duct pipe product pipeion line are not allowed to be unplugged and plugged under power, otherwise it will cause serious consequences.
Trouble and solution:
Fault 1: The equipment of the air duct pipe product pipeion line does not lift the knife when punching a small mouth
Analysis: It may be that the solenoid valve is blocked by debris
Treatment: Check whether the solenoid valve is energized, and if it is energized, check whether the hydraulic oil in the fuel tank has been replaced on schedule. The hydraulic oil needs to be replaced regularly. Contact Primapress Mechanical Machinery Service Department in time.
Fault 2: The punching die and the shearing knife of the air duct pipe product pipeion line equipment cannot move
Analysis: 1. It may be that the connection line of the electrical box controlling the hydraulic solenoid valve is disconnected;
- The intermediate relay of the electrical box may be damaged;
- The automatic processing page of the touch screen is displayed as the state of no punching or the solenoid valve is stuck.
Treatment: Check whether the electrical circuit or equipment of the machine is damaged, replace and repair it in time, and contact Primapress Machinery after-sales service department in time.
Fault 3: After the air duct pipe product pipeion line equipment starts product pipeion, the size of the sheet is unstable or the sheet just keeps walking
Analysis: 1. The position of the encoder status switch in the lower right corner of the touch screen is valid;
- The encoder installed at one end of the measuring wheel is loose, slips, or breaks;
- The encoder is damaged or the signal line is broken.
Treatment: Check the encoder and signal line to see if there is any deviation or damage, repair and replace it in time, and contact Primapress Machinery after-sales service department in time.
Fault 4: The touch screen of the air duct pipe product pipeion line equipment displays the emergency stop and servo alarm of the system and flashes
Analysis: The emergency stop button next to the touch screen is not released, the servo motor has foreign objects, or the servo motor circuit is unstable
Remedy: Release the emergency stop button next to the touch screen, check the running track of the servo motor and the guide rail for sagging, check whether the connecting wire of the servo motor is broken or loose, and contact the Primapress Machinery after-sales service department in time.
Fault 5: The product pipes produced by the air duct pipe product pipeion line equipment have cracks and scratches
Analysis: It may be that the raw materials of the product pipe are unqualified or the product pipeion process has problems, and there are foreign objects in the machine parts.
Handling: Check whether the raw materials are qualified and whether the operator neglects to bring sharp foreign objects into the leveling stick.
Other glitches:
- The touch screen displays the hydraulic overload alarm and flashes
Solution: Check whether the system pressure of the hydraulic station of the air duct pipe product pipeion line is too high, whether the oil temperature is too high, whether the oil pump is damaged and the thermal relay is tripped, disassemble the electrical box cover, and manually reset the thermal relay.
- The uncoiler does not stop feeding or does not feeding.
Solution: Check whether the photoelectric switch for the material inspection of the air duct pipe product pipeion line is damaged or the connecting line is disconnected. Whether the discharge sensor switch is placed in the correct position. The time relay in the uncoiler box is damaged, check and replace it.
