Drawing die recommend grades
The application of drawing dies
Wiredrawing dies a wide range of USES, such as electronic devices, radar, television, instruments and spaceflight high-precision silk material used and common tungsten, molybdenum wire, stainless steel wire, cable wire and various alloy with SiDou is drawing mode control out of the diamond, diamond wire drawing die due to the natural diamond, which has strong as raw materials of high wear resistance, the use of life.
Drawing dies is all sorts of metal wire manufacturer (such as wire enterprise GangSiChang, electrode welding wire, wire factory etc) control of a kind of very important easy debilitating mold. The drawing dies is very extensive, mainly used for drawing bar, wire, silk material and pipe materials for linear difficult-to-machine objects, steel, copper, tungsten, molybdenum etc of metal and alloy material drawing processing. Due to the cost of drawing die drawing expenses accounts for the 1/2 above, therefore, how to decrease wiredrawing mould cost, improve its service life is metal wire production unit urgent need to address the problem.
How selection the tungsten carbide drawing dies?
Although wiredrawing mode can be used for processing all kinds of steel, copper, tungsten, molybdenum etc metal and alloy material of different materials, but drawing die each have its applicable machining scope, therefore drawing mould material is rational selection of key to ensure successful application to obtain the longest die longevity. Different material wiredrawing mold all have its relatively reasonable processing object.
According to the material drawing mode can be divided into alloy steel, hard alloy mould, natural diamond die, polycrystalline diamond mold, CVD diamond die and ceramic mold and so on many kinds. And widely used in electronic devices, radar, television, instruments and aerospace and other high-tech industries, with strong abrasion resistance, service life is extremely high.
For example, in the copper wire drawing the same diameter, polycrystalline diamond die when the service life is hard alloy die life of 300 to 500 times when drawing nickel wire is only 80 ~ 100 times, drawing molybdenum wire, its life only hard alloy die life of 50 ~ 80 times, and pull out carbon steel, polycrystalline diamond die life is hard alloy die 20 ~ 60 times.
Blind in drawing mode choice, the friction wear complex, generally divided into destruction and friction and wear two kinds big. The drawing mode damage can divide again ring damage, stretching damage, shear failure and bearing surface damage etc, friction and wear can be divided into abrasion wear, friction wear and corrosion wear, bruises and fine particles produce wear etc.
The above several damage and friction and wear form may often intertwined, drawing mode for analysis the destruction of an increased level of difficulty wear mechanisms. But overall, the wear resistance of drawing mode of various materials from high to low ranking is: diamond wiredrawing modes (not consider natural diamond anisotropic problem) - ceramic wiredrawing mode - hard alloy wire drawing die -- has eliminated the alloy steel
