Abstract
The utility model discloses a die spring, which is formed by winding a flat steel bar with four side corners being fillets. The thickness of the flat steel bar decreases from the outer to the inner of the spring. Since the spring is formed by winding the flat steel bar with the four side corners being the fillets, and the thickness of the flat steel bar decreases from the outer to the inner of the spring, when the spring is under pressure, the stress on the flat steel bar is damped from the inner to the outer. In addition, the stress on the four corners of the flat steel bar can be dispersed by the fillets. Therefore, the utility model can reduce the risk of breaking the flat steel bar due to stress concentration under pressure, improve the stability of the spring in use, and prolong the service life of the spring.
Description
Technical field
The utility model relates to a kind of spring, particularly a kind of mould spring.
Background technique
At present, common on the market a kind of mould is mainly formed by the coiling of flat steel bar with its structure of spring, in use, the pressure that spring bore is very big, excessive pressure-loaded makes pressure focus on four jiaos of flat steel bar on the flat steel bar easily, causes spring breakage, and working life is not long, at above-mentioned shortcoming, be necessary to make improvements.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, use stable, the mould spring of easy-rupturing not.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of mould spring, described spring is formed by the flat steel bar coiling of corner, four sides rounding, the thickness of this flat steel bar along spring outside towards the inside attenuation.
Wherein, upper and lower surface of described flat steel bar and bi-side are cambered surface.
The beneficial effects of the utility model are: owing to the flat steel bar coiling of the utility model by corner, four sides rounding forms, and the thickness of flat steel bar along spring outside towards the inside attenuation, behind the spring pressurized, the suffered stress of flat steel bar is cushioned by the inside out face, on the other hand, the stress that the flat steel bar is four jiaos can disperse by fillet, said structure has reduced flat steel bar pressurized and has produced easy the concentrating of stress and the phenomenon of generation fracture, improve the stability when spring uses, prolonged working life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the part-structure schematic representation of flat steel bar in the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of mould spring, described spring is formed by flat steel bar 1 coiling of corner, four sides rounding 2, the thickness of this flat steel bar 1 along spring outside a towards the inside b attenuation.
Because the utility model forms by flat steel bar 1 coiling of corner, four sides rounding, and the thickness of flat steel bar 1 along spring outside a towards the inside b attenuation, behind the spring pressurized, flat steel bar 1 suffered stress is cushioned by the inside out face, on the other hand, the stress that the flat steel bar is 1 four jiaos can pass through fillet 2 to be disperseed, and said structure has reduced flat steel bar 1 pressurized and produced easy the concentrating of stress and the phenomenon of generation fracture, improve the stability when spring uses, prolonged working life.
In the utility model, by flat steel bar 1 upper and lower surface and bi-side are designed to the globoidal structure that dimpling goes out, this structure can effectively be disperseed flat steel bar 1 suffered stress equally, has improved its stability and working life.
The utility model is rational in infrastructure, use is stable, easy-rupturing not, is a kind of mould spring that is widely used in the manufacturing industry.
Claims (2)
1. mould spring, it is characterized in that: described spring is formed by flat steel bar (1) coiling of corner, four sides rounding (2), the thickness of this flat steel bar (1) along the spring outside towards the inside attenuation.
2. a kind of mould spring according to claim 1 is characterized in that upper and lower surface of described flat steel bar and bi-side are cambered surface.
