drawing stainless steel wire production process


Stainless steel wire, also known as stainless steel wire, made of stainless steel for the production of various types of different specifications and models of silk products, the origin of the United States, the Netherlands, Japan, the cross section is generally round or flat. Common corrosion resistance is good, cost-effective stainless steel wire is 304 and 316 stainless steel wire.

Stainless steel wire drawing in the drawing force under the action of the wire rod or wire rod from the drawing die die hole to produce small cross-section of the wire or non-ferrous metal wire plastic processing process. All kinds of metal and alloy of different cross-sectional shape and size of the wire can be used to pull production. Pull out the wire, the size of the precise, smooth surface, and the use of drawing equipment and die is simple, easy to manufacture.

drawing stainless steel wire production process

In the drawing process, the pull-out stress σ1 of the pulling force on the cross-sectional area of ​​the drawn wire is applied to the die. In order to make the plastic deformation of the metal in the die hole, the tensile stress σ1 must be greater than the deformation resistance of the metal in the deformation zone of the die hole. In order to prevent the wire from being deformed after the die hole is deformed, Pulling process, the tensile stress σ1 must be less than the yield limit σs of the drawn wire after the die hole, so the conditions for realizing the drawing process are usually expressed as: σT <σ1 <σs. The ratio of K to their ratio is called the safety factor of the drawing process.


The stress state of the wire drawing is the three-way principal stress state of the two-way compressive stress, which is easier to reach the plastic deformation state than the three-way compressive stress. The deformation state of the drawing is a three-way main deformation state in which the two-way compression deformation is always torsional deformation, which is disadvantageous to the plasticity of the metal material, and it is easier to produce and expose the surface defects. The deformation of the wire drawing process is limited by the safety factor. The deformation of the wire is small, and the number of passes is much higher. Therefore, the multi-pass continuous high-speed drawing is often used in the production of the wire.
