What are the types of core materials for drawing dies?2021-04-25T02:45:50+00:00

The wire drawing die industry has experienced decades of development, and many new core materials for wire drawing dies have emerged.

According to the types of materials, the wire drawing dies can be divided into alloy steel dies, tungsten carbide dies, natural diamond dies, polycrystalline diamond dies, CVD diamond dies and ceramic dies.

The development of new materials greatly enriches the application range of the wire drawing die and increases the service life of the wire drawing die.

Comparison of the advantages and disadvantages of various drawing die materials:

Drawing dies materialAdvantageDisadvantageApplication
Alloy steel drawing diesEasy to makePoor wear resistance and short lifeBasically eliminated
Natural diamond drawing dies (ND Drawing Dies)High hardness and good wear resistanceBrittle and difficult to processUsed to manufacture wire drawing die cores with a diameter of less than 1.2mm
Tungsten carbide drawing dies (TC Drawing Dies)Good polishability and low energy consumptionPoor wear resistance and difficult processingVarious diameter wires
Polycrystalline synthetic diamond drawing dies (PCD Drawing Dies)High hardness and good wear resistanceDifficulty in processing and high costSmall wire, metal wire
CVD coating material drawing dies (CVD Drawing Dies)High finish, good temperature resistanceComplex process, difficult to process
Ceramic material drawing diesWear resistance, high temperature resistance, good corrosion resistanceThermal shock, poor toughness, difficult processingNo large-scale application
What is the work area structure of the drawing dies and function?2021-07-21T02:56:18+00:00

Structure of the wire drawing dies coreThe structure of the wire drawing dies core can be divided into five sections according to the nature of the work:

  • Bell Radius: It is convenient to thread and prevents the wire from scratching the drawing dies from the entrance direction.
  • Entrance Angle: Through it, the steel wire can be easily brought into the lubricant.
  • Approach Angle: The main part of the die hole, where the deformation process of the steel wire is carried out, that is, the original section is reduced to the required section size.
  • Land: Its function is to obtain the exact size of the drawn wire.
  • Back Relief: Used to prevent the steel wire from being unsteady and scratching the surface of the steel wire.

The inner diameter profile of the drawing dies is very important, it determines the tension which is required to compress the wire and affects the residual stress in the wire after drawing.

With the increase of the wire drawing speed, the service life of the wire drawing dies has become a prominent problem. Americans T Maxwall and E G Kennth proposed a new wire drawing dies hole pattern theory suitable for high-speed wire drawing, that is, the “straight line” theory. The wire drawing dies made according to this theory has the following characteristics:

  • The entrance area and lubrication area are combined into one, which has a tendency to reduce the lubrication angle so that the lubricant is subjected to a certain pressure before entering the working area, so as to achieve a better lubrication effect.
  • The entrance area and working area are lengthened to establish a better lubrication pressure, and the angles are optimized according to the drawing material and the compression rate of each pass.
  • The sizing area must be straight and reasonable in length.
  • The vertical line of each part must be straight.
