Abstract
The invention relates to a buffer suitable for preventing a sliding block from rebounding after collision. The buffer comprises a cylinder. A cylinder cover is arranged at the opened end of the cylinder in a sealed mode and seals an opening. A center through hole is formed in a central axis of the cylinder cover. A piston rod penetrates through the center through hole and a piston body assembly is arranged at the top end of the piston rod. When buffering is performed, the right end face of the cylinder serves as a contact face which is collided with the sliding block. An electromagnetic coil is arranged in a side wall of the cylinder in a wound mode. A pressure sensor for detecting pressure of media is arranged on the right end face of the piston body assembly and connected with a processor module. When the sliding block is collided with the right end face of the cylinder, based on a media pressure value, the processor module controls a current drive module to output currents matched with the medium pressure value so as to make the electromagnetic coil generate a corresponding magnetic field to be combined with the sliding block in an attracted mode until the medium pressure value detected by the processor module is a balanced value; the processor module controls the current drive module to cut off outputting of the currents to release the sliding block.
