What are the common faults and solutions of the flattening machine?
Flattening machine is a commonly used equipment in industries such as metal processing, pipe forming, forging, etc. During long-term operation, various faults may occur, affecting production efficiency and processing accuracy. The following are several common types of faults in flattening machines and their corresponding solutions:
1、 Common mechanical failures and their solutions
1. The flattening machine is stuck or moving unevenly
Possible reasons:
Insufficient lubrication of sliding parts
Severe wear of guide rails or bearings
There is a foreign object stuck in the moving part
resolvent:
Check and replenish lubricating oil or grease
Replace worn guide rails or bearings
Clean up foreign objects and keep the equipment clean
2. Abnormal vibration or noise of the equipment
Possible reasons:
Loose anchor bolts or weak foundation
Loose or worn transmission components (chains, gears)
Abnormal motor or gearbox
resolvent:
Check the fasteners and re fix the equipment
Replace worn transmission components
Check if the motor bearings or reducers are damaged and replace them if necessary
3. Uneven flattening or inability to flatten
Possible reasons:
Poor or damaged mold alignment
Pressure system failure or insufficient pressure
The workpiece size does not match or the material is abnormal
resolvent:
Check if the mold installation is in place, repair or replace the mold
Check if the pressure of the hydraulic or pneumatic system meets the standard
Ensure that the material and specifications of the workpiece meet the requirements
2、 Hydraulic system related faults
4. Insufficient hydraulic system pressure
Possible reasons:
Oil pump wear or damage
Pressure regulating valve malfunction
Insufficient oil or deterioration of oil quality
resolvent:
Check and replace the oil pump
Adjust or replace the pressure regulating valve
Supplement hydraulic oil and replace with high-quality oil
5. Hydraulic oil leakage
Possible reasons:
Oil pipe aging or rupture
joint looses
Seal aging
resolvent:
Replace the aging oil pipe
Tighten the connector
Replace sealing rings (such as O-rings, oil seals, etc.)
3、 Electrical system malfunction
6. Motor does not start or responds slowly
Possible reasons:
Power supply phase loss or unstable voltage
Poor contact of control circuit
The starter or contactor is damaged
resolvent:
Check the power supply voltage and phase
Check the wiring, terminals, and relays inside the electrical control box
Replace damaged electrical components
7. Control system malfunction (such as unresponsive touch or button)
Possible reasons:
Control panel damaged
PLC program error or not started
Loose or disconnected wiring
resolvent:
Replace or repair the control panel
Check the running status of the PLC and download the program again
Check the connection of signal lines and cables
4、 Issues related to operation and maintenance
8. Incorrect or inefficient repeated pressing of workpieces
Possible reasons:
Improper operation by workers or non-standard operating procedures
Lack of limit device or malfunction of position sensor
Unreasonable design of processing rhythm
resolvent:
Strengthen operator training and standardize operating procedures
Repair or replace limit switches/sensors
Optimize the process flow or program logic
5、 Preventive maintenance recommendations
To reduce the frequency of flattening machine failures, the following maintenance measures should be regularly performed:
Check the content of the project cycle
Check and add lubricating oil to the lubrication system daily or weekly
The hydraulic system is checked weekly for oil volume, pressure, and any leaks
Monthly inspection of loose wiring, aging circuits, and equipment grounding in the electrical system
Clean, inspect for wear, and lubricate the mold and indenter after each use
Perform weekly no-load test runs on the entire machine to observe for any abnormal noise or shaking
Summary:
The common faults of the flattening machine are mainly concentrated in the mechanical system, hydraulic system, electronic control system, and operation and use. By timely inspection, standardized operation, and regular maintenance, the failure rate can be effectively reduced, the service life of equipment can be extended, and production efficiency can be improved.
