Circular Line Straightening Machine User Guide: A Comprehensive Analysis of the Entire Process from Installation to Maintenance
I. Equipment Installation Specifications
1. Venue preparation requirements
Ensure that the ground flatness error of the installation area is ≤3mm/m²
(2) Reserve an operation space of more than 1.5 meters around the equipment
(3) The power supply configuration should comply with the fluctuation range of ±5% of the rated voltage of the equipment
2. Basic installation steps
(1) Use a level to adjust the equipment base. The height difference at the four corners should be no more than 0.5mm
(2) The tightening torque of the anchor bolts should reach ±5% of the standard value
(3) Adjust the tension of the main drive belt to the specified deflection value
3. Auxiliary system connection
(1) The pneumatic system pipeline needs to be equipped with an oil-water separator
(2) The coolant pipes are connected with anti-corrosion materials
(3) The grounding resistance value should be ≤4Ω
Ii. Operating Procedures
Check the list before starting up
(1) Confirm that the oil levels at each lubrication point are within the range indicated by the scale
(2) Check whether the gap between the straightening rollers is uniform
(3) Verify the effectiveness of the emergency stop button function
2. Parameter setting standards
The input error of the wire diameter is controlled within ±0.1mm
(2) The length setting should take into account a thermal expansion and contraction coefficient of 0.3%
(3) The straightening speed is set according to the hardness classification of the material
3. Production operation monitoring
(1) The first item must undergo straightness testing
(2) Sample and check the dimensional accuracy every two hours
(3) Observe the fluctuation range of the motor current in real time
Iii. Key Points for Daily Maintenance
Periodic maintenance plan
(1) Daily: Remove the metal residue on the surface of the rollers
(2) Weekly: Check the wear condition of the transmission system
(3) Monthly: Replace the lubricating oil of the reducer
2. Maintenance of key components
The roundness of the straightening roller is inspected every 500 hours
(2) The guiding device should be lubricated with special grease every week
(3) The shearing tool maintains a grinding Angle of 20°±1°
3. Electrical system maintenance
(1) Check the tightness of the terminal blocks every month
(2) Check the operating status of the PLC module every quarter
(3) Insulation resistance tests should be conducted annually
Iv. Common Fault Handling
1. Precision anomaly investigation
(1) Excessive straightness: Check the arrangement sequence of the rollers
(2) Large length error: Calibrate the encoder signal
(3) Surface scratches: Adjust the feeding guide device
2. Mechanical fault handling
(1) Abnormal vibration: Check the anchor bolts and bearings
(2) Transmission slippage: Adjust the tension of the belt
(3) Material jamming handling: Immediately stop the machine and operate in reverse
3. Electrical fault diagnosis
(1) Motor overload: Check the voltage and mechanical load
(2) Sensor failure: Clean the detection surface
(3) PLC alarm: Refer to the fault code manual
V. Safety Precautions
1. Operational protection requirements
Protective glasses and gloves must be worn
(2) Long hair should be coiled into the work cap
(3) It is strictly prohibited to operate with rings or other accessories
2. Warning of dangerous areas
(1) Safety light curtains are set up in the shearing area
(2) Protective covers are installed on the transmission components
(3) Warning signs should be pasted on high-temperature areas
3. Emergency response measures
When material jamming occurs, the machine must be completely shut down for handling
(2) In case of electrical faults, cut off the power supply first and then carry out maintenance
(3) In case of mechanical abnormality, press the emergency stop button immediately
Vi. Suggestions for Technological Upgrades
1. Intelligent transformation direction
(1) Install a CCD online detection system
(2) Upgrade the adaptive control system
(3) Connect to the MES production management system
2. Energy-saving optimization measures
(1) Transform the variable frequency drive system
(2) Install an energy feedback device
(3) Optimize the efficiency of the hydraulic system
The technical specifications and suggestions provided in this guide need to be adjusted and implemented according to the specific equipment model and the technical documents of the manufacturer. It is recommended to establish a complete equipment file to record each maintenance and fault handling situation, providing data support for equipment life cycle management.
