Preparation method of composite material serpentine spring

Abstract

The invention relates to a preparation method of a composite material serpentine spring. The preparation method comprises the following steps that 1), basalt unidirectional cloth and resin are selected for later use; 2), basalt fiber unidirectional cloth is cut into the shape matched with the size characteristics of the designed composite material serpentine spring, the cut basalt fiber unidirectional cloth is infiltrated with resin, and the basalt fiber unidirectional cloth infiltrated with the resin is laid in a mold to form a preformed body; 3), an inner mold and an outer mold on which the preformed body is laid are closed, and proper temperature and mold pressure are selected, so that the composite material serpentine spring is cured and formed; 4), after curing forming and demolding of the composite material serpentine spring are completed, the composite material serpentine spring is put into a constant-temperature box to be subjected to post-curing, and after post-curing treatment is completed, deburring and polishing treatment is conducted on the composite material serpentine spring, and the composite material serpentine spring is obtained. The prepared composite material serpentine spring has the advantages of being light in weight, resistant to corrosion and the like, has a limiting function, and can remarkably improve the safety and reliability of a coupler.

Description

【Technical field】 [0001] The invention relates to a method for preparing a spring, in particular to a method for preparing a composite material serpentine spring, and belongs to the technical field of springs. 【Background technique】 [0002] Serpentine spring coupling has the advantages of metal spring coupling and non-metal spring coupling at the same time. It can not only transmit large torque but also compensate large displacement and buffer vibration. The serpentine spring coupling connects the flange hubs on both sides through the serpentine spring with both elasticity and toughness, so it has large load-bearing torque, good flexibility, high transmission efficiency, long service life, and can allow large radial displacement. Axial displacement and angular deviation, easy disassembly and assembly, are widely used in mining machinery. [0003] At present, serpentine springs are generally made of carbon steel, which is heavy and easy to rust. With the increasingly serio...

[0004] Moreover, in the actual working process, the serpentine spring coupling is often used in heavy mining machinery, which not only needs to transmit high torque but also needs to absorb shock and compensate displacement. The displacement compensation needs to have a certain limit method
