Features of Tungsten Carbide Wire Drawing Die

Although the materials of the drawing die can be different, among different drawing dies, the cemented carbide drawing dies to become the highlight. Today, tungsten carbide wire drawing dies to occupy an important position in the wire drawing industry. In this article, we will bring you the following characteristics of carbide wire drawing dies:

1. Strong power resistance

During the process of wire drawing and extrusion, the wire drawing die will be subject to large extrusion, bending stress, impact, and other messy loads. Therefore, the material selected to make the wire drawing die should have high power resistance and outstanding hardenability after heat treatment to ensure that the die can be uniformly hardened.


2. Excellent wear resistance

The wire drawing die should have high wear resistance to ensure normal service life and mass production of high-quality wire. Generally speaking, the hardness of tungsten carbide is directly proportional to the wear resistance under certain conditions. Therefore, the drawing die must have high hardness and wear resistance. In addition to hardness, the determining factors include thickness, composition, excess amount of matrix after heat treatment and the number, size, type, dispersion, and red hardness of carbides. The tungsten carbide content of tungsten carbide is more than 80%, and its wear resistance is several times higher than that of steel. Therefore, in order to prolong the service life of the wire drawing die, the material is mostly made of cemented carbide.


3. Sufficient heat resistance

For continuous production of wire, the temperature of tungsten carbide wire drawing dies may reach 200°C, which will reduce the strength and hardness of most materials, and tungsten carbide is a material with excellent thermal stability, which can maintain its properties at high temperatures.


4. Excellent processability

The wire drawing die must go through a long time to pull out the wire with high precision. Typically, casting, cutting, grinding, heat treating, or other finishing is required. Therefore, only materials with excellent processing properties can meet production needs. The excellent craftsmanship of cemented carbide molds will be the best choice.


These characteristics of the wire drawing die are reflected in its raw material, tungsten carbide, which has the characteristics of high hardness, wear resistance, good thermal stability, and excellent processing performance.

I am a Wire Drawing Machine, and I need Maintenance I am a wire drawing machine, which is composed of bearings, motors, yarn guide rods, forced beam splitters, controllers, etc. From the day I was assembled, passed the inspection, and left the factory, my mission and meaning have been doomed. Contribute to producing good fiberglass. When I came to the new factory, after being installed and debugged, I started my work. The two machine heads exchanged with each other, and the glass fiber was drawn out from the platinum bushing by winding and pulling.  The bundle comb is wound on the machine head covered with the paper tube, and the cycle is repeated until the set time is up, the machine head is changed, and the traction is continued. Throughout the year, from winter to spring, I work like time, non-stop operation, although it is hard work, hard work, day and night, but I will also get sick, the long-term wear and tear of parts, let me The sound of "creak" and "kuang kuang...

What is a Wire Drawing Machine? Wire drawing machine is a widely used mechanical equipment in industrial applications, widely used in machinery manufacturing, metal processing, petrochemical, plastics, bamboo, wood products, wire and cable, and other industries. Types of Wire Drawing Machine Wire drawing machines can be divided into metal wire drawing machines according to their uses (for the production and preprocessing of metal products such as standard parts); Plastic wire drawing machine (used in the plastic products industry to use polyester, nylon, polyethylene, polypropylene, polyester chips, etc. as raw materials to produce various hollow, solid round wires or flat wires for deep processing of special equipment); Bamboo wood wire drawing machine (special equipment for making chopsticks, toothpicks, barbecue sticks, etc. in the bamboo and wood products industry to pull out bamboo wire and wood wire for reprocessing), etc.
