Description
Technical field
The invention belongs to the steel part technical field, be specifically related to a kind of high-performance profiled steel wire material and manufacture method thereof and application.
Background technique
Produce at present the used steel wire of high energy of deformation spring and mainly contain following two kinds: 1. being the high energy of deformation spring of coiling behind the steel wire draw down of circle with the cross section, is that trapezoidal steel wire comes the high energy of deformation spring of coiling with the cross section 2..And the steel wire of above two kinds of shapes all is a soft state, also will quench behind the good spring of coiling, just can make spring reach the performance requirement of design.The shortcoming of making the coiling spring with the steel wire of above two kinds of shapes is that distortion of materials during owing to coiling can't make the cross section of Spring Steel Wire become accurate rectangle.And when the design spring, maximum energy of deformation is arranged in order to guarantee spring, require the cross section of Spring Steel Wire must keep accurate rectangle.To heat-treating, in heat treated process, be difficult to keep spring configuration indeformable in addition, be easy to generate waste product, increase cost of production, cause waste of material with the spring after the soft material processing.
Summary of the invention
The object of the present invention is to provide a kind of high performance section wire material and preparation method thereof, this section wire material can be used for the high-quality spring of coiling, and the cross section that makes Spring Steel Wire is accurate rectangle.
