The use of the cutting machine must be powered on before it can be started. If the machine is switched on and off every day, the use frequency of the switch is also very high. Such high-frequency operation will inevitably lead to some problems for various reasons, such as aging failure and so on. Today, the Xiaobian of Dongguan Qixin mechanical equipment Co., Ltd. - cutting machine, cutting machine manufacturer and cutting machine manufacturer comes to learn about the possible switching faults of cutting machine and how to solve these problems.

Blanking switch: when pressing the blanking switch with both hands, the pressure head of the cutting machine does not press down. Please check whether the switch wiring is loose or the switch is damaged, and then check whether the pad protection switch is faulty (some cutting machine manufacturers do not have a pad protection switch, which can be ignored, and please look down for the specific problems of the pad protection switch). If there are no problems above, please continue to check whether the intermediate relay is faulty. It is recommended to replace it. Finally, consider whether the solenoid valve coil is damaged.

First of all, there is not only one switch on the cutting machine. Each switch controls different parts, so the problems of each switch will be different. Of course, the problems of other electrical components and hydraulic components will also have the same problems. Power switch: when the power switch is started and the cutting machine is not powered on, first check whether the 380V voltage of the factory is normal, and then check whether the wiring of the power switch is loose and the switch is damaged, or check whether the thermal relay is overloaded. Oil pump start switch: when starting the oil pump start switch and the cutter motor is not running, please check whether the wiring of the switch is loose or the switch is damaged, and then check whether the 220V voltage of the transformer is energized.

Emergency stop switch: when the emergency stop switch is pressed, the pressure head of the cutting machine does not rise urgently. Please replace the switch immediately to avoid being unable to use in case of emergency in the process of use, resulting in huge losses. Setting switch: when the setting switch is opened and the pressure head of the cutting machine does not drop, set whether the switch wiring is loose or the switch is damaged.

Remarks: after the setting switch of the cutting machine is turned on, press and hold the blanking switch with both hands to lower the pressure head of the cutting machine. If the setting switch does not work, please check whether the wiring of the setting switch is loose or the switch is damaged, and then check whether the blanking switch is faulty.
