What is wire drawing die ?
The wire drawing die is a kind of die through which the metal wire passes from thick to thin, and gradually reaches the size that people need. This special die is the wire drawing die.
What is drawing dies used for?
Wire drawing die is a very important consumable product for various metal wire manufacturers to draw wire. The scope of application of the wire drawing die is very wide. It is mainly used for drawing linear difficult-to-process objects such as rods, wires, and pipes. It is generally suitable for drawing processing operations of metals and alloy materials such as steel, copper, tungsten, and molybdenum.
The core of the wire drawing die
The core of the wire drawing die is generally made of natural diamonds and artificial diamonds (artificial diamonds include mcd, pcd, synthetic materials, etc.). The copper wire drawing die belongs to the soft wire drawing die. There are also hard wire drawing dies, such as drawing tungsten wire and so on. The angle of the compression zone of the copper wire drawing die is generally 16-18 degrees, and the fixed diameter length is 30-40%, while the angle of the compression zone of the tungsten wire drawing die is relatively small, generally 12-14 degrees, and the fixed length is 60-70 %.
The application of drawing dies
Drawing dies are widely used, such as high-precision wires used in electronic devices, radars, televisions, instruments and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires are all drawn with diamond drawing dies. The diamond wire drawing die made of natural diamond has strong wear resistance and extremely high service life due to the use of natural diamond as raw material. The production process of wire drawing die insert includes several process steps such as pressing die, drafting die and turning.
Since the cost of the wire drawing die can reach more than 1/2 of the wire drawing cost, how to reduce the consumption cost of the wire drawing die and improve its service life is the primary problem that metal wire production units urgently need to solve.
Moresuperhard provide PCD wire drawing dies and MCD wire drawing dies.Dimaond wire drawing dies have good wear resistance and long services life.
Advantages of PCD wire-drawing die
-Much long use life -Suitable for long production runs
-Best choice for highly corrosion wire materials
-Suitable for titanium wire materials
-Wire remains round, even with significant die wear.
Advantages of MCD wire-drawing die
-Good for fine and super fine wires
-Low surface friction
-Smooth wire surface
-Ultra-high accuracy wire available
<< ：Grinding Method of Diamond Tool
<< ：Advantages and disadvantages of wire drawing dies made of different materials
PCD tools need to be ground because after long-term use, the surface of the tool will accumulate cutting slag, wear and edge failure, resulting in a decrease in cutting performance. Grinding can restore the sharpness and geometry of the tool, extend its service life, and improve processing efficiency and quality.
Alumina ceramic has high hardness (HV1900~2100) and high brittleness (flexural strength 240~260MPa). It is a typical hard and brittle material that is difficult to machine. Its grinding processing cost is high, the efficiency is low, and the surface and subsurface after grinding Crack groups appear in the area, affecting the stability of the workpiece.Moresuperhard have rich experience in grinding ceramic materials and we can recommand suitable grinding wheels for you.Moresuperhard have development different formulations grinding wheel for different ceramics materials.
