Abstract

The invention relates to a compression spring which comprises a spring body, wherein a metal wire is coiled in a stacked mode to form the spring body, the cross section of the metal wire approximates to be in a regular hexagon shape, and a reinforcement layer is installed on the outer surface of the spring body. Compared with a spring with the same number of coils and the same length, a round spring having the same cross sectional area and namely a spring having the same elasticity, the compression spring achieves that gaps among the spring coils are larger, larger compression space of the spring is obtained, and a better compression effect is achieved. Due to the fact that the reinforcement layer is installed, the fatigue strength of the compression spring is enhanced obviously, and the fatigue life of the compression spring is prolonged by more than one time. Meanwhile, corrosion resistance of the compression spring is enhanced, and cost of the high-strength compression spring is effectively lowered.

Description

A kind of Compress Spring
Technical field
The present invention relates to the spring field, relate in particular to a kind of Compress Spring.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to come work, generally makes with spring steel.Impact or shake, store up the size of energy, measuring force etc. in order to motion, the mitigation of controlling parts, be widely used in machine, the instrument.Spring is an accumulator just, and it has the function of stored energy, but can not discharge energy at leisure, realize that this function of slow release should lean on " spring+big speed ratio mechanism " to realize, is common in mechanical watch.Spring had just been used very early, and the bow in ancient times and crossbow are exactly two kinds of sensu lato springs.By stressed character, spring can be divided into extension spring, Compress Spring, torsion spring and flexural spring, belleville spring, annular spring, leaf spring, helical spring, valute spring and torsion bar spring etc. can be divided into by shape, cold coiling spring and hot coiling spring can be divided into by working process.The common cylinder spring is simple owing to making, and can make various types according to the stand under load situation, and is simple in structure, therefore most widely used.In general the manufactured materials of spring should have high limit of elasticity, fatigue limit, impact toughness and good heat treatment performance etc., and commonly used have carbon spring steel, alloy spring steel, rustproof spring steel and Cuprum alloy, nickel alloy and a rubber etc.The manufacture method of spring has cold coiling method and hot rolling method.Some spring also will be suppressed or shot blast after making, and can improve the bearing capacity of spring.
Compress Spring is that a kind of machinery holds the power structure, extensive use in modern industry, but existing extension spring comprise the spring body, described spring body is formed by stacking by metal wire rod is curling, the cross section of described metal wire rod generally all is circular, and the spring of the same number of turns and length is during compression, since between the spring ring apart from less, compression volume is also less, so its compression effectiveness is poor, the cushioning effect that can reach is also bad; And fatigue fracture to occur in Compress Spring, and antiseptic effect is poor.
Summary of the invention
The objective of the invention is provides a kind of Compress Spring in order to overcome the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of Compress Spring comprises the spring body, and described spring body is formed by stacking by metal wire rod is curling, and the cross section of described metal wire rod is approximately regular hexagon, and described this external surface of spring is provided with a strengthened layer.
Further, the cross section of described strengthened layer is identical with the shape of the cross section of metal wire rod.
Further, described strengthened layer contains emery or silicon carbide.
Further, the thickness of described strengthened layer is 3-5mm.
Further, the both ends of the surface of described spring body are the plane and are parallel to each other.
Compared with prior art, the invention has the beneficial effects as follows: Compress Spring provided by the invention, compare the spring of the same number of turns and length, the spring of the circle of same cross sectional area size, it is the suitable spring of elastic force, space between the spring ring is larger, reaches spring and has larger compression volume, has preferably compression effectiveness; And by strengthened layer is set, so that spring reduces or has eliminated the tired dangerous defective on spring surface greatly, significantly improve the fatigue strength of spring, be enhanced about more than once the fatigue life of spring, improve simultaneously the corrosion resistance of spring, effectively reduced the cost of high-strength spring.

Fig. 2 is the structural representation of a kind of Compress Spring cross section of the present invention.
Embodiment
In order to make purpose of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
See also Fig. 1 and Fig. 2, Fig. 1 is a kind of Compress Spring structural representation of the present invention, and Fig. 2 is the structural representation of a kind of Compress Spring cross section of the present invention.
A kind of Compress Spring, comprise spring body 1, described spring body 1 is formed by stacking by metal wire rod is curling, and the cross section 2 of described metal wire rod is approximately regular hexagon, Compress Spring provided by the invention, compare the spring of the same number of turns and length, the spring of the circle of same cross sectional area size, i.e. the suitable spring of elastic force, the space between the spring ring is larger, reach spring and have larger compression volume, have preferably compression effectiveness.
Described spring body 1 outer surface is provided with a strengthened layer 3, and the cross section of described strengthened layer 3 is identical with the shape of the cross section of metal wire rod 2, and described strengthened layer 3 contains emery or silicon carbide, and the thickness of described strengthened layer 3 is 3-5mm.The present invention is by arranging strengthened layer 3, so that spring reduces or has eliminated the tired dangerous defective on spring surface greatly, significantly improve the fatigue strength of spring, be enhanced about more than once the fatigue life of spring, improve simultaneously the corrosion resistance of spring, effectively reduced the cost of high-strength spring.
The both ends of the surface of stating spring body 1 are the plane and are parallel to each other.Be set to the plane by end face, so that stopping that spring can be stable when putting makes things convenient for putting and transporting of spring, also have more aesthetic property simultaneously.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
