Abstract
The invention relates to a cambered surface disc spring and a manufacturing method thereof. The cross section of the cambered surface disc spring is designed into a tapered arch shape; the arch shape is a heave or a pit on the basis of a tapered shape; the arch rise and the arc length of the arch shape are changed along with the cone height and the diameter of the disc spring; and the arch rise of the arch shape is less than 1/3 of the cone height. The cambered surface disc springs with same arch shapes and different arch shapes can be combined together for use. The cambered surface disc spring adopting the design greatly improves the overload safety guarantee of the disc spring, greatly improves the reliability, safety and service life of the disc spring, and prevents major failure accidents and economic losses.
Description
Technical field
The invention belongs to the belleville spring technical field, particularly a kind of high-performance cambered surface disc spring.
Background technique
As the important form of spring technical field, it is big that the dish spring has rigidity, and therefore the characteristic that stroke is short, is used in a large number in fields such as military project, Aero-Space, metallurgy, petrochemical industry, electric power, machine-building, railway transport and electrical equipment control.The present widely used structural type overwhelming majority is tapered cross section, also a spot of taper trapezoid cross section is arranged, though the dish spring use occasion of these section forms is had any different, but the mechanical characteristic of dish spring does not change, that is to say that the dish spring extremely flattens from taper, its deformation power change nature is the straight line or the curve of one section continuous whole basically, and the last Point of Strength of dish spring and lower support point are that relative fixed is constant.
And use the problem that is occurred in the dish spring to be in reality, because the relative fixed of last Point of Strength and lower support point is constant, often produce stressed stress of dish spring and tired concentrating, easily cause the dish spring on above-mentioned 2, to produce and break or decrease of fatigue strength, cause the early failue of dish spring; On the other hand; according to dish spring design code; safe allowable load is not more than 75% of dish spring effective travel; surpass and then do not have safety assurance; and the possibility that can lower working life greatly and be destroyed rapidly, yet existing dish spring does not have the structural design of overload protection, in the actual using process; the situation that short-term surpasses allowable load happens occasionally, and safety can't ensure.
So reliability, safety guarantee and the working life of improving the dish spring, the development of equipment is made in modern industry production and basis, and avoid economic loss, minimizing harm that significant values and meaning are arranged.In disclosed dish spring invention of in May, 2006, its publication number: CN1776247A is to be provided with damping body on dish spring body, purpose is to make the distortion of dish spring be subjected to obstruction, attenuation vibration, alleviate noise,, do not address the above problem though the resonance effect of eliminating under the natural frequency of spring own is also arranged.
Summary of the invention
The present invention seeks to invent and a kind ofly can prevent effectively that dish spring breaking when work from the high-performance cambered surface disc spring and the using method that can provide overload to ensure again being provided and decrease of fatigue strength.
For achieving the above object, technological scheme of the present invention provides the high-performance cambered surface disc spring of a kind of structural design novelty, process step economy and multiple using method.It is characterized in that the Cross section Design of dish spring is the taper arc, arc is projection or a depression on the basis of taper, and the sagitta of arc, arc length are that awl height and the diameter with the dish spring changes, the sagitta of its arc less than awl high 1/3; When the involutory stack of dish spring is subjected to force compresses, because surface of contact is a cambered surface up and down, the force bearing point of dish spring can be with the variation of compression stroke by the central point displacement of initial section edges to the cross section, otherwise, when the dish spring stretches, its force bearing point can prevent that effectively traditional dish spring is because of Point of Strength is fixed, stress is concentrated breaking or the decrease of fatigue strength problem of being caused with the variation of stretching travel by the central point in the cross section edge dislocation to the cross section; On the other hand because the structural design of high-performance cambered surface disc spring is that tapering and radian are synthetic, the mechanical characteristic of this and traditional dish spring has significant difference, the deformation power change nature of its compression is that awl becomes the backarc change earlier, the deformation power change nature of its resilience is that first arc becomes back awl change, the linear relationship that is showed also is two line segments that flex point is arranged, and the flat loading force of arc transformation is 1.5 times of the flat loading force of awl transformation at least, that is to say, 75% o'clock of the dish spring effective travel of allowable load regulation, the bearing capacity of high-performance cambered surface disc spring is a times of traditional dish spring at least, and this has just improved the overload guarantee of dish spring greatly; Greatly improve reliability, Security and the working life of dish spring, prevented major failures accident and economic loss.Figure 13, the 14th, traditional dish spring, the comparison of the mechanical characteristic curve of high-performance cambered surface disc spring.
The material source of high-performance cambered surface disc spring provided by the invention is extensive, can adopt material preparations such as spring steel, stainless steel and high-temperature nickel-base alloy, and Economy and application of temperature, environmental working condition broadness is characterized in that, the adopting process step is:
The first step will forge, roll after annealing or solid molten the processing through the metallic material of melting,
Second step, adopt die stamping or turning system dish spring blank, put surplus 0.2-0.5 millimeter,
In the 3rd step, grinding is to the requirement of dish spring thickness deviation, and precision is: Ra1.6-3.2
In the 4th step, on press machine, adopt the compression moulding of specific complex mould; ,
The 5th step, carry out preheating, quenching, tempering heat treatment according to properties of materials, HRC requires 41-48,
In the 6th step, suppress: in groups involutory to dish spring monolithic with oil hydraulic press, normal temperature is suppressed greater than 5 times;
In the 7th step, dish spring cambered surface is carried out enhancement process or taked ageing treatment with shot-blasting machine;
The 8th step, surface anticorrosion, antirust processing.
The application process of high-performance cambered surface disc spring provided by the invention is various, can carry out multiple combination according to reality, it is characterized in that, a plurality of reed bodies of identical arc are superimposed, involutory or compound.The reed body of different arcs is single involutory, a plurality ofly is separated by superimposedly, and the reed body of different arcs is single involutory, a plurality of be separated by superimposed.
The invention advantageous effect:
Because the present invention has above-mentioned formation, can prevent that dish spring breaking when work from producing and decrease of fatigue strength the reliability and the working life of greatly having improved the dish spring;
Because the present invention has above-mentioned formation, can improve the overload guarantee of dish spring and enlarge using scope, the Security that has greatly improved the dish spring effectively prevents major failures accident and economic loss.
Because the present invention has above-mentioned formation, the operating mode occasion broadness of its Economy and application of temperature, environment, economic value height.
