Manhart How to judge the abnormality or failure of the punching and shearing machine?

When judging the abnormality or failure of the punching and shearing machine, you can follow the following steps and key points:
1. **Observe the operating performance**:
– Pay close attention to the operating performance of the punching and shearing machine, including cutting effect, equipment operation stability, noise level, etc. If the cutting effect is not good (such as uneven cuts, burrs, etc.), abnormal equipment vibration or increased noise is observed, it may be a precursor to abnormal conditions or failures.
2. **Monitor abnormal sounds**:
– The punching and shearing machine will have a certain sound during normal operation, but if you hear screaming, abnormal friction or impact, this may be caused by hydraulic system problems, mechanical parts damage or transmission system problems.
3. **Check the electrical system**:
– Electrical failure is one of the common types of failures of punching and shearing machines. Regularly check the power supply line, motor operation status, control panel power supply and signal lines, etc. to ensure that the electrical system is working properly.
4. **Check the hydraulic system**:
– The hydraulic system is an important part of the punching and shearing machine. Common hydraulic system failures include hydraulic pump failure, hydraulic oil temperature is too high, hydraulic cylinder oil leakage, etc. By observing the color and level of the hydraulic oil, checking the oil temperature indicator, etc., you can judge whether the hydraulic system is normal.
5. **Check mechanical parts**:
– The failure of mechanical parts will affect the overall operation of the punching and shearing machine. Regularly check the wear of the blade, whether the slider moves smoothly, whether the transmission device is damaged, etc. Especially the blade, its wear degree will directly affect the cutting effect.
6. **Evaluate the safety protection device**:
– The safety protection device of the punching and shearing machine is the key to ensure the safety of the operator. Check whether the light curtain is damaged, whether the emergency stop button is effective, whether the safety door is flexible, etc., to ensure that the safety protection device is in good condition.
7. **Check materials and working environment**:
– Improper handling of materials or problems in the working environment may also cause the punching and shearing machine to malfunction. For example, unstable material stacking may cause the equipment to vibrate more during processing; too humid or too high a temperature in the working environment may cause damage to electrical components.
8. **Check records and alarm information**:
– If the punching and shearing machine is equipped with a fault diagnosis system or alarm device, the relevant records and alarm information should be checked regularly to detect and handle abnormal conditions or faults in time.
When judging the abnormal situation or failure of the punching and shearing machine, the following points should be noted:
– For different abnormal situations or failures, the possible causes and solutions are different, and specific problems need to be analyzed specifically.
– For more complex failures or uncertain situations, you should seek the help of professional technicians in time to avoid aggravating the problem or causing greater losses by handling it yourself.
– When dealing with abnormal situations or failures, you should follow the corresponding operating procedures and safety requirements to ensure the safety of personnel and equipment.
