Abstract
The utility model discloses a compound spiral compression spring, which comprises two coaxial spring bodies with the same rotation direction. The cross sections of the two spring bodies adopt a rectangular or trapezoidal shape, and have the opposite declination directions. The compound spiral compression spring adopting the technical scheme is equivalent to the combination of a plurality of disk springs, so as to increase the rigidity of the compound spiral compression spring. Because the compound spiral compression spring is made of two parallelly-connected spring bodies with the same rotation direction, the rigidity of the compound spiral compression spring remains the characteristic of a spiral spring.
Description
Technical field
The utility model relates to the spring field, relates in particular to a kind of composite screw pressure spring.
Background technique
Spring is widely used a kind of elastic element in machinery and the electron trade, and spiral compression spring is most widely used, and it is circular that the cross section of the used spring material of spiral compression spring mostly is, and secondly is rectangle, avette, multiply shape.In order to improve stress phase, improve fatigue strength in recent years, also reduce the difficulty of made simultaneously, the spring in flat cross section is used and has been obtained great popularization.The flat wire cylindroid helicalcoil compression spring is a kind of novel powerful spring that the eighties grows up in the world, especially already is used widely in the mould grown place.At some special occasions, the spring of prior art can not satisfy usage requirement during the requirement pressure spring that demand rigidity is big in certain space.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the novel purpose of this use provides a kind of composite screw pressure spring that rigidity is big in certain space.
Technological scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
A kind of composite screw pressure spring comprises two spring bodies that coaxial rotation direction is identical, and the material section of two spring bodies is a rectangle or trapezoidal, and its true dip direction is opposite.
Material section size shape same tilt angle as preferred described two spring bodies is opposite according to the horizontal plane symmetry.
Described two spring bodies are cylindrically coiled spring.
Described two spring bodies rely on the elastic force of self to be pressed on together.
Beneficial effect:
1, the composite screw pressure spring comprises two spring bodies that coaxial rotation direction is identical, the material section of two spring bodies is a rectangle or trapezoidal, its true dip direction is opposite, has been equivalent in the space of a spring two springs in parallel, and composite screw pressure spring rigidity is improved significantly.
2, the material section size shape same tilt angle of described two spring bodies is opposite according to the horizontal plane symmetry, has guaranteed also when the rigidity of composite screw pressure spring is improved that its rigidity approaches constant more.
3, described two spring bodies are cylindrically coiled spring, the rigidity of composite screw pressure spring be further enhanced and the processing and fabricating method simple.
4, described two spring bodies rely on the elastic force of self to be pressed on together, adopt the composite screw pressure spring of this technological scheme to be equivalent to several butterfly springs and be superimposed, when rigidity is greatly improved and guaranteed that the rigidity of this composite screw pressure spring is constant in working stroke.
