Solutions to the Failure of Press Brake Bending Machine

Is there any fault when you operate the 3D press brake bending machine? If there is any fault, how to solve it? Here is a brief introduction to the solution of the 3D press brake bending machine:


1. The reversing valve can not reverse or everse slowly. It is generally caused by poor lubrication, spring stuck or damaged, oil or impurities stuck in the sliding part. In this way, you should first check whether the oil mist device works normally; whether the viscosity of lubricating oil is appropriate. If it's necessary, replace the lubricating oil, clean the sliding part of the reversing valve, or replace the spring and the directional valve.


2. After a long time of use, the valve core seal ring is easy to be worn, the valve stem and valve seat are damaged, which leads to the leakage in the valve, slow action of the valve or failure of normal reversing. At this time, the seal ring, valve stem and valve seat should be replaced, or the directional valve of the press brake bending machine should be replaced.


3. If the intake and exhaust holes of the solenoid pilot valve are blocked by sludge and other impurities, the sealing will be not tight, the movable iron core will be stuck, and the circuit will be faulty. Those will all cause the directional valve can not be normally reversed. At this time, the oil sludge and impurities on the pilot valve and movable iron core should be cleaned.
