Operating method staged-buffering multistage buffer

Abstract

The invention relates to an operating method of a staged-buffering multistage buffer. During buffering operation, the right end face of a cylinder body of a final-stage buffer serves as a contact surface colliding with a slide block; an electromagnetic coil is arranged in a side wall of the cylinder body of the final-stage buffer in a surrounding manner; pressure sensors for detecting medium pressures are arranged on the right end faces of piston body components of all stages of buffers respectively, and connected with a processor module; when the slide block 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 values to allow the electromagnetic coil to generate a corresponding magnetic field to attract the slide block according to the medium pressure value; and when the piston body components of the buffers make piston motion, a processor adjusts or closes back-and-forth medium flow of the corresponding cylinder body to control the motion speeds or buffering stages of the piston body components according to the medium pressures detected by the pressure sensors.

Description

technical field [0001] The invention relates to a working method of a buffer, in particular to a working method of a hierarchical buffering multi-stage buffer. 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 working method of a multi-stage buffer with hierarchical buffering. The working method of the multi-stage buffer is suitable for automatically adjusting the buffer stages of the multi-stage buffer when the slider is impacting the buffer....
