Manhart Как бороться с нештатными ситуациями, которые могут возникнуть в процессе гибки?

When dealing with abnormal situations that may occur during the bending process, the following are some specific steps and strategies to ensure efficient and accurate problem solving and minimize production losses:
I. Identify abnormal situations
1. Bending angle error: The angle of the part after bending is inconsistent with the preset value.
2. Extrusion deformation: During the bending process, the part is extruded and deformed, affecting the bending angle and quality.
3. Abnormal upward speed: The upward speed of the bending machine is sometimes fast and sometimes slow or unstable.
4. Oil pump abnormality: The oil pump cannot start normally or stops after starting.
5. Servo communication failure: The servo axis (X/Y/R axis) cannot communicate, affecting the motion accuracy.
II. Analyze the cause of the problem
1. Bending angle error: It may be caused by damage and wear of accessories such as the bottom die and push rod, unstable machine tool adjustment, inconsistent thickness of the oxide coating on the surface of the material, etc.
2. Extrusion deformation: It may be due to unreasonable arrangement of the bottom die and push rod, improper bending position, low tool design and processing accuracy, etc.
3. Abnormal upward speed: may be caused by equipment failure (such as motor, valve, etc.), incorrect parameter setting, different material properties, etc.
4. Abnormal oil pump: may be caused by the emergency stop switch not being released, oil pump output and feedback signal line problems, motor overcurrent protection, etc.
5. Servo communication failure: may be caused by incorrect servo parameter settings, abnormal communication line between PLC and servo, etc.
III. Take corresponding solution strategies
1. Bending angle error:
– Replace damaged and worn accessories such as bottom die, push rod, etc.
– Keep the machine tool stable and adjust the position of bottom die, push rod, etc.
– Pay attention to the surface condition of the material before processing to ensure that the surface of the material is clean.
2. Extrusion deformation:
– Select appropriate bottom die and push rod according to the shape and size of the part.
– Adjust the bending position and angle.
– Use high-precision tools.
3. Abnormal upward speed:
– Check whether the motor, valve and other equipment are normal, repair or replace the faulty parts.
– Reset parameters, and test and adjust.
– Set different process parameters according to the characteristics of different materials.
4. Oil pump abnormality:
– Check whether the emergency stop switch is released to ensure that the line connection is normal.
– Long press the oil pump icon to start the oil pump, and check the oil pump output and feedback signal.
– Check the motor overcurrent protection, adjust the motor parameters or replace the motor if necessary.
5. Servo communication failure:
– Check whether the servo parameter settings are correct.
– Check whether the communication line connecting the PLC to the servo is normal, and repair or replace the damaged line.
– Check whether the communication line connecting the servo and the servo is normal to ensure a stable connection.
IV. Preventive measures and follow-up management
1. Regular maintenance: Perform regular maintenance on the CNC bending machine, including cleaning, lubrication, tightening and other operations to ensure that the equipment is in good working condition.
2. Maintenance management: Strengthen equipment maintenance management, regularly check key components and wearing parts, and replace or repair them in time.
3. Operation training: Provide professional training for operators to ensure that they understand equipment performance, operating procedures and abnormal handling methods.
4. Data analysis: Collect and analyze equipment operation data to identify potential problems and solve them in a timely manner.
Through the above steps and strategies, we can deal with abnormal situations that may occur during the bending process in a more systematic and efficient manner, and improve production efficiency and product quality.
