A method of working buffer rebound impact adapted to prevent the slider

The present invention relates to a working buffer, comprising: a cylinder, the open end of the cylinder head is provided, and the opening is closed, the central axis of the cylinder head provided with a central through hole; worn by a piston rod through the central through hole, and the tip of the rod is provided with a piston assembly; work buffer, a right end surface in contact with the slide surface of the cylinder collision; side wall of the cylinder of the electromagnet is provided around the piston a right end surface of the assembly is provided with a pressure sensor for detecting pressure of the medium, the pressure sensor is connected to a processor module; when the slider strikes the right end surface of the cylinder, the processor module is adapted to pressure medium, a control output current of the current drive module and the fluid pressure value matches the electromagnet to produce a corresponding magnetic field to pull said slider; until the processor module when the medium pressure is measured by the equilibrium value, the control module turns off the output current drive current to release the slider.
