Heat treatment method for metal vibration isolator and its curved thin plate

Abstract

The invention relates to the technical field of mechanical vibration isolation and metal heat treatment, and provides a metal vibration isolator, comprising at least two curved thin plates and two connecting plates, the curved thin plates are metal elastic elements; the connecting plates are made of metal ; The two connecting plates are set up and down correspondingly, one end of each curved thin plate is fixed on the upper connecting plate, and the other end is fixed on the lower connecting plate. The metal vibration isolator has a long life, is not afraid of high temperature and takes up little space. Also provided is a heat treatment method for the curved thin plate of the metal vibration isolator. The curved thin plate of the metal vibration isolator is heat-treated by means of the inner mold plate and the outer mold plate, and after the inner mold plate, the outer mold plate and the curved thin plate are combined, the Under certain conditions, after annealing, quenching and tempering heat treatment steps, the performance of the curved thin plate of the metal vibration isolator is enhanced, the vibration isolation effect and service life are improved, and the metal vibration isolator can be used on precision instruments and equipment.

Description

technical field [0001] The invention relates to the technical field of mechanical vibration isolation and metal heat treatment, in particular to a metal vibration isolator and a heat treatment method for a curved thin plate thereof. Background technique [0002] Now many aspects need to use equipment or instruments. The stability and accuracy of equipment and instruments are often affected by various vibrations, and sometimes even produce unexpected damage effects, which may cause equipment and personnel casualties in severe cases. In addition, the source of vibration and the vibration it transmits will also cause various noises, which will affect people's physical and mental health. Therefore, it is often necessary to add vibration isolation measures at the source of vibration or a certain section of the vibration transmission path to reduce the harm caused by vibration. [0003] The vibration isolators used in various projects are based on cost and performance considerati...

AI Technical Summary

Problems solved by technology

However, spring, rubber and wire rope vibration isolators are worse than quasi-zero stiffness vibration isolators and air spring vibration isolators in terms of vibration isolation performance.

[0004] Since the spring material itself occupies nearly half of the space in the vibration isolation direction of the spring type vibration isolator, it is necessary to increase the space to have a better vibration isolation effect; the vibration isolation effect of the rubber type vibration isolator is greatly affected by the temperature, and its life It is shorter than metal vibration isolators; because the wire rope vibration isolators are distributed in different positions of the steel ropes, the tensile force suffered by the load deformation is very different, resulting in different life of the internal filaments. After a period of time, the performance of the vibration isolator changes. In addition, the dynamic and static stiffness ratio of the wire rope vibration isolator is 6-10. For the same rated load, the vibration isolation effect of this vibration isolator is worse than the previous two types.

[0005] Existing metal vibration isolators, some have limited vibration isolation effect, some have more complex structures, more consumables, are heavy in weight, and some are easily damaged
