Why does the shearing machine not cut the knife

The reasons why the shearing machine does not cut the knife may include:

Relief valve blockage: The relief valve is an important part of the hydraulic system, which is used to keep the system pressure stable. If the relief valve is blocked, the pressure of the hydraulic system will be abnormal, which will affect the normal operation of the plate shears. ‌
Electrical limit: Electrical problems are also one of the common reasons for cutting machine knives. If the electrical limit is not set properly or the electrical component fails, it may prevent the shearing machine from working properly.
Foot switch, oil pump bad: foot switch and oil pump is an important part of the operation of the shearing machine, if these parts are damaged, it will also lead to the shearing machine can not work normally.
Cylinder oil leakage or seal damage: Oil cylinder oil leakage or seal damage will lead to insufficient pressure of the shearing machine, which will affect the shear effect. In this case, damaged parts may need to be replaced or repaired. ‌
