Embodiment 1

[0022] See figure 1 and Image 6 , a working method of automatically attracting and releasing the buffer of the slider, the buffer comprises: a cylinder 4 which is cylindrical and used to fill the buffer medium, and the open end of the cylinder 4 is sealed with a cylinder Cover 5, a piston rod 6 is fitted with a piston rod 6 in the center through hole of the cylinder head 5, the right end of the piston rod 6 is provided with a piston body assembly 7, and the piston body assembly 7 is suitable for being a piston in the cylinder body 4. During the buffering operation, the right end face of the cylinder block 4 serves as the contact surface that collides with the slider 10, and the right end face is covered with a buffer pad 4-2 for buffering the impact of the slider 10; the cylinder block 4 An electromagnet 4-1 is axially arranged in the side wall of the piston body assembly 7, and a pressure sensor 9 for detecting medium pressure is arranged on the right end surface of the pis...

Embodiment 2

[0028] See figure 2 and image 3 , the buffer is a three-stage buffer, including: a first-stage buffer 1, an intermediate-stage buffer 2 and a final-stage buffer 3; the first-stage buffer 1, the intermediate-stage buffer, and the final-stage buffer 3 are respectively It includes: a cylinder body 4 which is cylindrical and used for filling the buffer medium, a cylinder cover 5 is sealed at the open end of the cylinder body 4, and a piston rod 6 is sealed and movably fitted in the central through hole of the cylinder cover 5, The right end of the piston rod 6 is provided with a piston body assembly 7. The piston body assembly 7 is suitable for piston movement in the cylinder body 4, and is movably and sealingly matched with the inner wall of the cylinder body 4; wherein, the first stage The cylinder 4 of the buffer 1 constitutes the piston rod 6-1 of the intermediate buffer 2, and the cylinder 4 of the intermediate buffer 2 constitutes the piston rod 6-2 of the final buffer 3;...

Abstract

The invention relates to a working method of a buffer automatically attracting and releasing a slider. The buffer comprises a cylinder block, a cylinder cover is arranged at the opening end of the cylinder block and closes the opening, and a center through hole is formed in the center 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 work is performed, the right end face of the cylinder block serves as a contact face where the buffer collides with the slider; an electric magnet is arranged in the axial direction in the side wall of the cylinder block, a pressure sensor used for detecting medium pressure is arranged on the right end face of the piston body assembly, and the pressure sensor is connected with a processor module; when the slider impacts the right end face of the cylinder block, the processor module is suitable for controlling a direct current driving module according to a medium pressure value to output a direct current matched with the medium pressure value, and the electric magnet is made to generate a corresponding magnetic filed to attract the slider; until the processor module detects that the medium pressure value is a balanced value, the processor module controls the direct current driving module to output a reverse current to release the slider.

Description

technical field [0001] The invention relates to a buffer, in particular to a buffer using elastic colloid as a buffer medium. Background technique [0002] In the field of shock absorption, shock absorbers 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 cannot work in time, causing the slider to rebound. How to avoid this occurrence is a technical problem in the art. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide a working method for automatically attracting and releasing the buffer of the slider, which solves the technical problem that the slider rebounds when the slider impacts the buffer. [0005] The present invention provides a working method for automatically attracting and releasing a buffer of a sliding block, wherein the buffer...
