Abstract
The invention relates to a high-strength spring which comprises an integrally-formed spring body. The spring body is formed by curling and overlaying a steel wire. The two end faces of the spring body are planes and arranged in parallel. The cross section of the steel wire is composed of a trapezoidal face and arc faces, the arc faces are composed of the large arc face and the small arc face, a first arc chamfer is arranged at the joint of the large arc face and the trapezoidal face, and a second arc chamfer is arranged at the joint of the small arc face and the trapezoidal face; the first arc chamfer is the R0.95 chamfer, and the second arc chamfer is the R1.10 chamfer. The high-strength spring is high in strength and long in service life by overcoming machining deformation.
Description
Technical field
The present invention relates to a kind of elastic component, be specifically related to a kind of spring.
Background technique
Spring is a kind of mechanical parts utilizing elasticity to carry out work, in order to control parts motion, relax impact or vibrations, storage or saving energy, measuring force size etc., be widely used in machine, instrument.Common spring cross section generally is rectangle, in course of working, there will be deformation, thus reduces the elastic coefficient, can not meet the application of high request.
Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome deficiency of the prior art, to provide a kind of intensity high, overcome processing deformation, the high-strength spring of long service life.
Technological scheme: in order to solve the problems of the technologies described above, a kind of high-strength spring of the present invention, it comprises integrated spring body, described spring body is formed by stacking by steel wire rod is curling, the both ends of the surface of described spring body are plane and arranged in parallel, the cross section of described steel wire rod is made up of trapezoidal faces and arc shaped surface, described arc shaped surface is divided into large arc shaped surface and little arc shaped surface, described large arc shaped surface and trapezoidal faces joint are provided with the first arc angling, described little arc shaped surface and trapezoidal faces joint are provided with the second arc angling, described first arc angling is R0.95 chamfering, described second arc angling is R1.10 chamfering.
The top of described trapezoidal faces with below than being 3:5 to 9:10.
Described spring body is made up of single circle body, and each circle body and horizontal line are 10-20 °.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the cross section of steel wire rod of the present invention is made up of trapezoidal faces and arc shaped surface, described large arc shaped surface and trapezoidal faces joint are provided with the first arc angling, described little arc shaped surface and trapezoidal faces joint are provided with the second arc angling, described first arc angling is R0.95 chamfering, described second arc angling is R1.10 chamfering, the top of described trapezoidal faces with below than being 3:5 to 9:10, ensure in course of working, overcome processing deformation, improve the elastic coefficient; Each circle body and horizontal line are 10-20 ° and ensure that spring maintains high strength; Spring body is by the curling superposition once-through of steel wire rod, and both ends of the surface are plane and arc be arranged in parallel, and whole service life is long, realistic usage requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of spring body described in the present invention;
Fig. 2 is the cross sectional representation of spring body described in the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of high-strength spring of the present invention, it comprises integrated spring body 1, described spring body 1 is formed by stacking by steel wire rod is curling, the both ends of the surface of described spring body 1 are plane and arranged in parallel, the cross section of described steel wire rod is made up of trapezoidal faces 2 and arc shaped surface, described arc shaped surface is divided into large arc shaped surface 3 and little arc shaped surface 4, described large arc shaped surface 3 is provided with the first arc angling 5 with trapezoidal faces 2 joint, described little arc shaped surface 4 is provided with the second arc angling 6 with trapezoidal faces 2 joint, described first arc angling 5 is R0.95 chamfering, described second arc angling 6 is R1.10 chamfering, the top of described trapezoidal faces 2 with below than being 3:5 to 9:10, described spring body 1 is made up of single circle body 7, and each circle body and horizontal line are 10-20 °.The cross section of steel wire rod of the present invention is made up of trapezoidal faces and arc shaped surface, described large arc shaped surface and trapezoidal faces joint are provided with the first arc angling, described little arc shaped surface and trapezoidal faces joint are provided with the second arc angling, described first arc angling is R0.95 chamfering, described second arc angling is R1.10 chamfering, the top of described trapezoidal faces, ensures in course of working, overcome processing deformation than being 3:5 to 9:10 with below, improves the elastic coefficient; Each circle body and horizontal line are 10-20 ° and ensure that spring maintains high strength; Spring body is by the curling superposition once-through of steel wire rod, and both ends of the surface are plane and arc be arranged in parallel, and whole service life is long, realistic usage requirement.
The invention provides a kind of thinking and method; the method and access of this technological scheme of specific implementation is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, some improvements and modifications can also be made; these improvements and modifications also should be considered as protection scope of the present invention, and all available prior art of each constituent element not clear and definite in the present embodiment is realized.
