CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

The common malfunction of electric- hydraulic press brake  and solutions 1. Slide can't move down quickly  The poppet valve is not connected and the spool is stuck  The spool of the directional valve which controls filling valve is stuck, can't be reset  The orifice of the filling valve is blocked  The proportional valve is abnormal  The mechanical part is too tight 2. There is large synchronization error between two cylinders when slider quick moves down  There is large friction difference between the two guide rails  There is large friction difference between the two cylinders  The connection between one cylinder and slider is skew, radial force  Check whether the damping in the filling valve control port which is on synchronous block is blocked  Check whether the filling valve is stuck  Check whether the cylinder, slider is too tight  The proportional valve is abnormal 3.The system does not build ...
