Multi-stage buffer with grading buffering effect

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.

Description

technical field [0001] The invention relates to a buffer, in particular to a multi-level buffer for hierarchical buffering. Background technique [0002] In the field of cushioning and shock absorption, buffers are widely used, and their main functions are to absorb various impact energy, protect equipment and reduce noise. [0003] However, when the slider hits the buffer, because the impact energy is too large, the piston in the buffer has no time to work, causing the slider to rebound. How to buffer in stages to overcome the impact force of the buffer slider is a technical problem in the art. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a multi-stage buffer with hierarchical buffering, which is suitable for automatically adjusting the number of buffer stages of the multi-stage buffer when the slider is impacting the buffer, so as to smoothly buffer the movement slider in . [0005] The present invention p...
