In major industries, many industries have used rocker cutting machines, such as cutting leather, handbags, gloves and small handicrafts. There are many kinds of rocker cutting machines, but as long as there is a little common sense, it can be judged according to the following description in case of problems.

When the rocker cutting machine is operating, the stamping head does not act:

1. Check whether the connector of the handle button switch falls off. If the connector does not fall off, please operate the button switch with both hands to check whether the button indicator light on the circuit board is on. If the light is on, it means that the switch and the circuit board are normal. If the light is not on, do not rush to judge that the circuit board is broken, please continue to check, and check whether the transformer 24V or 30V is powered with a meter, If there is no power, please continue to check whether there is voltage at the primary 380V of the transformer. If there is power at the primary, please replace the transformer at the secondary five points.

2. Fine tune whether the positioner is short circuited. Use the resistance gear of the meter to check whether the resistance value of the positioning connector is normal (0-1 value is normal, if it is not within this range, it is abnormal).

3. If there is no abnormality after completing the above points, please continue to check whether the solenoid valve is stuck. If the solenoid valve is stuck, first clean the solenoid valve and then install it. If it is still useless after cleaning, replace the solenoid valve.

The pressure of rocker arm cutter decreases:

1. The fine-tuning positioner is damaged, and the pressure does not change, so it needs to be replaced.

2. The oil pump is damaged and the internal part of the oil pump is worn, which needs to be replaced.

3. If the oil cylinder or oil pipe joint is loose, check whether there is oil leakage in the oil cylinder. According to the type of rocker arm cutting machine, the oil of a rocker arm overflows from below the head and above the casing, which can be easily seen. The second type of rocker arm cutter needs to open the oil tank cover to check whether the oil is injected at the bottom of the oil cylinder. If oil leakage is determined, replace the sealing ring in time. There is very little chance of oil leakage due to damage of oil cylinder and oil cylinder plunger, and remember to check whether the oil pipe joint is loose.

4. The hydraulic oil temperature is too high. For example, it suddenly becomes smaller or even has no pressure after being started and used for a period of time. There is pressure when it is used several hours after shutdown, and then there is no pressure when it is used for a period of time. In this case, it is recommended to replace the hydraulic oil. Remember not to buy low-quality hydraulic oil.

Unstable pressure of rocker cutting machine:

1. First check whether the fine-tuning positioner is damaged. For example, you can adjust different values of the positioner to empty cut for many times to feel whether the pressure is the same every time. If it is different for many times, it means that the positioner is insensitive and needs to be replaced. Another problem is that no matter how much the value of the positioner is adjusted, the pressure does not change, indicating that the positioner is broken and needs to be replaced.

2. Pressure instability will occur if the circuit board is not sensitive to contact and the solenoid valve is not sensitive.

Rocker arm cutter does not start:

1. Check whether the cable connector of the start button falls off and whether the start button is damaged. Check whether the start button is powered on. Measure the resistance value with a meter (if the meter pointer does not move, it indicates that it is normal).

2. Check whether the motor is missing and whether the three-phase power supply is normal.

3. Another kind of rocker cutting machine is equipped with thermal relay. Check whether the thermal relay protection jumps out. If it jumps out, press it and start it again. If it is useless, please replace the thermal relay.

The above are some problems written for the rocker cutting machine. Basically, some small problems can be solved. Of course, some problems should be clearly judged according to the types of rocker cutting machines. For example, there are two types of rocker cutting machines in the domestic market. A common is the domestic imitation of a British model more than 50 years ago. The second is to imitate the rocker arm cutting machine of Italian atom in recent years. With the change of the market, the imitation of Italy is gradually phasing out the imitation of Britain. However, due to the great technical difficulty and high requirements for processing equipment, there are very few domestic products that can imitate Italy.
