Abstract
The utility model discloses a high-compression and high-load flat spring, which has simple structure, and is highly stable, not easy to break, and applicable to a mold. The spring is formed by winding left and right side arc-shaped flat steel bars, wherein the flat steel bar becomes gradually thinner from outside to inside, and the upper and lower surfaces of the flat steel bar are inclined surfaces which incline from outside to inside. In the utility model, the spring is formed by winding the left and the right side arc-shaped flat steel bars, wherein the flat steel bar becomes gradually thinner from outside to inside, and the upper and lower surfaces of the flat steel bar are inclined surfaces which incline from outside to inside, so that the structure eliminates the acute angles, improves the appearance of the component, can effectively avoid the damage of the component caused by stress concentration, and prolongs the service life of the spring.
Description
Technical field
The utility model relates to a kind of spring, is specifically related to a kind of high load flat of high compression amount spring that is applicable to mould.
Background technique
The lenticular wire spring is the heavy load high compression amount spring of making at die feature specially, the cross section of existing mold spring mostly is the rectangle right angle side, its stress focuses on the corner of rectangle easily, and under long-term alternating stress effect, the higher corner of stress can progressively form hair line, crack tip stress is seriously concentrated, crackle is progressively enlarged, and the spring cross section constantly weakens, under overload is once in a while impacted, unexpected brittle fracture will take place in spring, has influenced the working life of spring.
Summary of the invention
In order to address the above problem, the utility model provides a kind of height simple in structure, stable, is not easy to rupture, be applicable to the high load flat of the high compression amount spring of mould.
The utility model is that the technological scheme that its problem of solution is adopted is: the high load flat of a kind of high compression amount spring, described spring is formed by the flat steel bar coiling that the left and right sides is arc surface, the upper and lower surface of the flat steel bar outer inclined-plane that tilts inwardly of serving as reasons, promptly the thickness of flat steel bar along the spring outside towards the inside attenuation.
Wherein, to be the intersection of arc surface and last lower inclined plane be rounding in the described left and right sides; Described spring is cylindric.
The beneficial effects of the utility model are: the utility model is formed by the flat steel bar coiling that the left and right sides is arc surface, and the thickness of flat steel bar along spring outside towards the inside attenuation, the inclined-plane that tilts inwardly outside the upper and lower surface of flat steel bar is served as reasons, said structure has been eliminated wedge angle, has been improved the profile of member, can effectively avoid stress to concentrate the component damage that causes, prolong the working life of spring.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is A-A ' direction sectional view of Fig. 2.
Embodiment
Referring to figs. 1 through Fig. 3, provided by the utility model a kind of simple in structure, stability is high, the high load flat of the high compression amount spring that is not easy to rupture, be applicable to mould, described spring is formed by flat steel bar 1 coiling that the left and right sides is arc surface 2, the thickness of flat steel bar 1 along spring outside towards the inside attenuation, the upper and lower surface of the flat steel bar 1 outer inclined-plane 3 that tilts inwardly of serving as reasons.
As preferred embodiment, the intersection that the described left and right sides is arc surface 2 and last lower inclined plane 3 is a rounding 4, and the stress that the flat steel bar is 1 four jiaos can disperse by rounding 4, and for guaranteeing that spring can bear heavy load, it is cylindric that spring is.
The utility model is formed by flat steel bar 1 coiling that the left and right sides is arc surface 2, and the thickness of flat steel bar 1 along spring outside towards the inside attenuation, the inclined-plane that tilts inwardly outside the upper and lower surface of flat steel bar is served as reasons, said structure has been eliminated wedge angle, has been improved the profile of member, can effectively avoid stress to concentrate the component damage that causes, prolong the working life of spring.
Certainly, the utility model is except above-mentioned mode of execution, and other equivalent technical solutions also should be within its protection domain.
Claims (3)
