Abstract
The invention relates to a multi-stage buffer with a grading buffering effect. During buffering, the right end face of a cylinder body of a buffer in the final stage serves as a contact surface for collision with a slider. Electromagnetic coils are wound on the side wall of the cylinder body of the buffer in the final stage. Pressure sensors for detecting medium pressure are respectively arranged on right end faces of piston components of buffers in different stages, and are connected with a processor module. When the slider collides with the right end face of the cylinder body, the processor module controls a current drive module to output current matched with the medium pressure value according to the medium pressure value, so that the electromagnetic coils generate corresponding magnetic fields to attract the slider. During piston motions of the piston components of the buffers in different stages, the processor module regulates or closes medium circulation flow in the corresponding cylinder bodies according to the medium pressure detected by the pressure sensors so as to control motion speed or buffer grades of the piston components.
