Building Slab Forming MachineCommon Faults, Causes, And Solutions
1、 Sheet Metal Forming Deviation, Left And Right DeviationPhenomenon: The Board Is Tight And Loose On One Side, The Board Edge Is Off Center, And The Width Is InconsistentReason:Asymmetric Clearance Between The Left And Right Feed Guide WheelsThe Height And Clearance Of The Forming Rollers Are Adjusted Differently On The Left And Right SidesSteel Coil Eccentricity And Uneven Unwinding TensionUneven Rack Foundation And Tilted Equipment PlacementSolve:Fine Tune The Left And Right Guide Wheels To Keep The Feed CenteredRe Calibrate The Level And Gap Of Each Forming RollerAdjust The Brake Tension Of The Unwinding Machine And Straighten The Steel CoilFlatten The Equipment Foundation And Calibrate The Overall Level Of The Machine2、 The Floor Slab Surface Is Twisted, Bulging, And CreasedPhenomenon: The Board Surface Has Hard Folds, Wavy Bumps, And Overall Distortion And UnevennessReason:The Angle Of The Roller Track Is Too Large, And The Bending Amount Is Too Rapid In One GoWear Of Rollers, Adhesion Of Iron Filings, And Uneven SurfaceThe Thickness Of The Board Is Not Compatible With The Machine, Either Too Thick Or Too ThinThe Rotation Speed Of The Front And Rear Rollers Is Not Synchronized, Causing Pulling And Pulling Of The Sheet MetalSolve:Fine Tune The Rollers One By One, Reduce The Bending Amplitude Of A Single Pass, And Gradually Form The ProductPolish And Polish The Rollers, Clean Up Iron Filings And Impurities, And Replace The Rollers If NecessaryFeed According To The Equipment Standard Plate Thickness And Do Not Produce Beyond The SpecificationsCheck The Transmission Chain And Reducer To Ensure Synchronous Speed3、 Inaccurate Cutting Size And Large Length ErrorPhenomenon: There Is A Significant Difference Between The Set Length And The Actual Board Length, With Fluctuations In Length And WidthReason:Loose, Slipping, Or Damaged Meter EncoderThe Feeding Speed Fluctuates Between Fast And Slow, And The Frequency Conversion Parameters Are UnstableHydraulic Cut-off Response Lag, Solenoid Valve JammingThe Board Slips And The Roller Pressure Is InsufficientSolve:Fix The Encoder, Check The Tightness Of The Counting Wheel, And Replace It If It Is DamagedReset The Parameters Of The Frequency Converter To Stabilize The Feeding SpeedClean The Hydraulic Solenoid Valve, Replace The Hydraulic Oil, And Inspect The Oil CircuitAdjust The Pressure Of The Material Roller Appropriately To Prevent The Board From Slipping4、 Hydraulic Cutting Is Powerless And Unable To Cut Through The Sheet MetalPhenomenon: Slow Cutting Under The Knife Holder, Inability To Cut Through The Steel Plate, And Large Burrs On The IncisionReason:Insufficient Hydraulic Oil, Deteriorated Oil, And High Oil TemperatureWear Of Hydraulic Oil Pump And Low Pressure AdjustmentThe Gap Between The Upper And Lower Blades Is Too Large, And The Blade Edge Is PassivatedOil Circuit Blockage, Dirty Filter Element BlockageSolve:Add Or Replace Hydraulic Oil, And Do A Good Job Of Heat Dissipation In SummerRaise The Hydraulic System Pressure And Inspect The Oil PumpFine Tune The Blade Clearance, Polish Or Replace The Alloy BladeClean The Oil Circuit And Replace The Hydraulic Filter Element5、 Machine Abnormal Noise And Large VibrationPhenomenon: There Is A Rattling And Buzzing Noise During Operation, And The Whole Machine ShakesReason:Chain Looseness, Wear And Lack Of OilBearing Damage, Roller Shaft EccentricityGearbox Oil Shortage And Gear WearLoose Foundation BoltsSolve:Tighten The Chain, Add Lubricating Oil, And Replace It If It Is Severely WornReplace Damaged Bearings And Correct Roller CoaxialityAdd Gear Oil To The Reducer, And Repair The Gears Due To Severe Wear And TearTighten All Anchor Bolts And Level The Shock Absorbers6、 PLC Touch Screen Malfunction, Failure To Start, Failure To CountPhenomenon: The Buttons Do Not Respond, Do Not Run Automatically, The Counting Does Not Move, And There Are Errors ReportedReason:Unstable Power Supply Voltage And Phase LossLoose Circuit, Broken Sensor Signal LinePLC Program Disorder, Touch Screen LagEmergency Stop Button Not Reset, Safety Protection TriggeredSolve:Check The Three-phase Voltage And Wiring, And Install A Voltage RegulatorCheck The Circuit Connectors, Tighten The Terminals, And Replace Damaged Signal WiresPower Off, Restart And Reset, And If Necessary, Re Import The ProgramReset Emergency Stop, Check Limit Switch And Safety Protection Device7、 Scratches And Peeling Of Galvanized Layer On The Board SurfacePhenomenon: Scratches On The Board Surface, Peeling And Rusting Of The Galvanized LayerReason:The Roller Has Burrs And Sharp CornersThe Adjustment Of The Guide Wheel And Pressure Wheel Is Too TightThere Are Iron Filings And Debris Between The Board And The RollerSolve:Polish The Edges And Corners Of The Grinding Roller To Remove BurrsAdjust The Clearance Between The Pressure Wheels Appropriately And Do Not Press Them Too TightlyClean The Surface Debris Of The Rollers Before Production To Maintain Cleanliness
