Abstract

The invention relates to a working method of a buffer. The buffer comprises a cylinder body and a cylinder cover which seals an opening, wherein a central through hole is formed in a position of a central axis of the cylinder cover; a piston rod penetrates through the central through hole, a piston body component is arranged at the top of the piston rod, and a right side end surface of an outer cylinder is connected to the tail end of the piston rod; during buffering work, the right end surface of the cylinder body is taken as a contact surface colliding with the sliding block; an electromagnet is arranged axially in the side wall of the cylinder body, and a pressure sensor used for detecting the medium pressure is arranged on the right end surface of the cylinder body and connected with a processor module; when the sling block collides the right end surface of the cylinder body, the processor module is suitable for controlling a current driving module to output a current which is matched with a medium pressure value according to the medium pressure value, so that an electromagnet produces a corresponding magnetic field and attracts the sliding block; and until the medium pressure value measured by the processor module is an equilibrium value, the current driving module is controlled to close the output current, so that the sliding block is released.

Description

technical field [0001] The invention relates to a working method of a buffer, in particular to a working method of a buffer using elastic colloid as a buffer medium. 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, due to the excessive impact energy, the piston in the buffer has no time to work, causing the slider to rebound. How to avoid this scene is a technical problem in this field. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a buffer working method, which solves the technical problem that the slider rebounds when the slider hits the buffer. [0005] The present invention provides a working method of a buffer, wherein the buffer includes: a cylindrical cylinder for filling with a buffer medium, a cylinde...
