Gantry punch manufacturers introduce the gantry punch maintenance and maintenance requirements:

1、 Lubrication system: two months after the first use of the lubrication system, clean the oil tank, pipeline and pipeline, and change the oil once. In the future, it can be cleaned every half a year, and according to the actual situation, the oil can be changed and cleaned regularly

2、 Electrical system: according to the line terminal screw, button switch, micro contactor, frequency converter, etc. to check once a month.

3、 Accuracy check: A. accuracy check is once a year. Please check according to the accuracy inspection record attached to the gantry punch when it leaves the factory. B. If the sliding surface is worn, repair or replace the rail and copper sleeve before correcting the accuracy（ Note when checking the accuracy, the flatness of the table should be considered.) 4、 At the end of the day, the operator should check the use of all parts of the gantry punch, and fill in the "anti pre maintenance card of the gantry punch", and fill in the "periodic inspection form of the gantry punch" during the regular inspection.

Gantry punch diagnosis technology:

1、 According to different diagnosis purposes and objects, signal detection selects the state signal which is convenient for diagnosis, and uses sensors, data collectors and other technical means to monitor and collect. Thus the database of state signals is established, which belongs to the initial mode.

2、 In feature extraction, the state signal of initial mode is amplified or compressed by signal processing, and the form is transformed to remove noise interference, so as to extract fault features and form the mode to be inspected.

3、 According to the theoretical analysis, combined with the fault cases, and using the fault archives established by the database technology as the reference mode, the state identification can distinguish the normal and abnormal of the equipment by comparing and classifying the mode to be inspected and the reference mode.

4、 After the decision-making of forecast is judged, the normal state can be continuously monitored and the above procedures can be repeated; For the abnormal state, it is necessary to find out the fault situation, make trend analysis, estimate the future development and continuous operation time, and put forward control measures and maintenance decisions according to the problem.
