General Introduction
Tungsten carbide wire drawing diesare professional dies used for the drawing processing of metal wires. They are mainly made of Tungsten Carbide materials, such as tungsten - cobalt carbide. These dies have extremely high hardness, wear - resistance, and good thermal stability. They are suitable for the continuous and high - precision size reduction and shape setting processing of metal wires.
Structural Characteristics
The typical structure of this kind of die is a cylindrical (or slightly tapered) tungsten Carbide Die core closely embedded in a circular steel sleeve. The inner hole of the die core has a bell - mouth, an entrance cone, a deformation (working) cone, a sizing belt, and an exit angle.
Performance Advantages
High Hardness: The hardness of tungsten carbide dies materials is close to that of diamond, which can withstand the intense wear when the wire passes through the die at high speed.
Good Thermal Conductivity: It helps to dissipate heat quickly, reducing the dimensional change of the die caused by thermal expansion and maintaining processing accuracy.
Low Friction Coefficient: Through surface treatment optimization, the friction force when the metal wire passes through the die is reduced, improving the drawing efficiency and reducing energy consumption.
Corrosion Resistance: It is suitable for processing various metal materials and is not easily corroded by the drawing materials.
Impact Resistance: It remains stable during high - stress drawing operations and is not prone to breakage.
Manufacturing Process
Selection of Carbide Grade: Common types include YG (tungsten - cobalt) and YW (tungsten - cobalt - titanium) series. The appropriate balance of wear - resistance and toughness is selected according to the use conditions.
Die Blank Processing: The matrix of the die is made. Usually, the powder metallurgy method is used to prepare TC DIES the blanks of the tungsten carbide die core and die sleeve.
Assembly and Insertion: There are hot - pressing and cold - pressing methods. The hot - pressing method is usually used in occasions requiring higher assembly accuracy and strength.
Application Areas
Tungsten carbide wire drawing dies have a wide range of applications in many manufacturing fields, such as wire and cable, metal wire mesh, spring, and fastener industries. They are key tools to improve the processing quality and efficiency of metal wires.
