Tungsten carbide wire drawing dies are manufactured using the following four steps in the process:

 

 

1. the process of creating molds made of tungsten carbide

The core of the hard alloy drawing die contracts as a result of the sintering process. The degree to which the core of different batches of the die contracts can vary from one another due to variations in composition, pressing, and the sintering process. The various die parts experience varying degrees of shrinkage during the manufacturing process; as a result, the finished product frequently has the shape of a saddle or bell mouth. The fluctuation in the shape and size of the die is in accordance with the standard of the die, but it significantly exceeds the interference requirement of the die set. Because of this, the outer circle of the die needs to be ground down, which necessitates the use of a specialized fixture that must be mounted on the grinder in addition to the utilization of a diamond grinding wheel.

2. The diameter of the mold core's outer diameter should be less than the diameter of the hole in the mold's innermost layer. Table 1 provides specific information regarding the actual interference level that was experienced during mold mounting. The die set features both the hot pressing method and the cold pressing method as two of its pressing options.

3. The processing of tungsten carbide for the mold sleeve components

The distinctive form of the mold sleeve is the result of turning it on a lathe. The following items collectively make up the control points:

It is necessary for the inner diameter roughness of the mold sleeve to reach 0.80 i in order to obtain a close fit with the mold sleeve.

This will ensure that the interference amount is calculated accurately for each mold by ensuring that the inner diameter of the mold sleeve corresponds to the outer diameter of the mold blank. This should be done for each mold individually.

After the mold sleeve has been installed, the bottom surface of the inner hole in the mold sleeve and the outer end of the mold must be parallel to one another in order for the mold to function properly.

It is recommended that the ellipticity of the inner hole of the mold sleeve be as small as possible, with a value that is no greater than 0. 4.

 

Cementing carbide onto mold mounting surfaces is the technical term for this process.

The process known as cold pressing involves pressing the blank into the mold sleeve while ensuring that the temperature does not rise above room temperature

It is advantageous in that it does not call for the use of any heating equipment, which results in cost and resource reductions related to heating

The following is a recommendation for an item that has gone through a significant amount of processing:

 

Wire Drawing Dies made of tungsten carbide can be processed using a machine that has multiple heads and can perform a variety of functions.

Equipment product usage

It is also capable of processing sizing belts with a large aperture, in addition to being used for the rapid reaming of cemented carbide drawings and the processing of the inlet and outlet areas. The eccentricity of the mold inner hole can be repaired thanks to the function of the mold sleeve, which extends from the mold core all the way up to the mold with an 80mm outer diameter. This function can be used to repair the eccentricity of the mold inner hole.

The machining range of the mold aperture is quite large, and an emery needle can be used to rapidly enlarge the hole in order to improve the processing efficiency. This can be done in order to maximize the potential of the mold. In addition, the polishing effect can be improved for molds that have a high number of mold apertures if the molds are polished properly.

Incorporated with a specialized vacuum cleaner that is fitted with synchronous control in order to remove dust at the appropriate time and preserve a clean environment for the apparatus.

Why use Tungsten Carbide Dies?

The hardness of tungsten carbide is almost three times that of steel, and its density is higher than that of titanium. Tungsten carbide is also denser than titanium. This finding is significant for companies that make use of dies because it reveals that a die made of tungsten carbide has a greater resistance to wear when compared to dies made of other materials. This is an important consideration for businesses that make use of dies. Diamonds have a hardness rating of 10, but they are not as versatile as other materials and are obviously a very expensive die material. Diamonds have a rating of 10 on the Mohs scale. On the Mohs scale, diamonds have a rating of 10 for their hardness. In particular, it has the hardest surface imaginable, and its thermal conductivity is the highest of any bulk material. Because diamond possesses these characteristics, the most important industrial applications of diamond are found in tools that are used for cutting and polishing. Because each grade possesses a different collection of characteristics, it follows that each grade is utilized in a distinct sector of the economy. The distinction between each of these grades is established by looking at the proportion of tungsten to carbon present in each of the respective quantities.

Because of its exceptionally high hardness as well as its adaptability to a variety of different uses, tungsten carbide is widely used in a wide variety of industrial applications. This is due to the fact that tungsten carbide is extremely versatile. Because it would take an impossibly long amount of time to compile a list of all of these products, the adaptability component of the equation comes into play at this point in the discussion.

Why The Tungsten Carbide Wire Drawing Dies Are Durable

TC Drawing Dies (see game products) is essential for the mold to have a long service life in the event that high-functioning and high-speed molds are used in the production process. In recent years, even for a modest amount of production, a high level of precision and reliability has become obligatory requirements. The best option will be using carbide dies that have a high resistance to wear.

The following characteristics of tungsten carbide wire PCD Drawing Dies contribute to the high durability of this material:

1. A formidable resistance to power

During the extrusion process, the mold should be subjected to very large amounts of extrusion, bending stress, impact, and any other types of messy loads. After undergoing heat treatment, the material that was chosen will consequently have a high power resistance. To ensure that the mold can be hardened to the same consistency throughout, the material used in the mold should have excellent hardenability.

2. Outstanding resistance to wear and tear

To ensure a normal service life for the mold and to produce a large quantity of extruded parts, the mold ought to have a high level of wear resistance. When certain conditions are met, there is a general correlation between the hardness of steel and its resistance to wear. Therefore, the material used to make the mold needs to have adequate hardenability. In addition to the material's hardness, other factors that play a significant role include its thickness, composition, and the amount of excess for the matrix that remains after heat treatment, as well as the quantity, size, type, dispersion, and red hardness of the carbide. The tungsten carbide has a wear resistance that is several times higher than that of steel, thanks to the fact that it contains more than 80% tungsten carbide. Therefore, carbide is typically used as the material of choice for drawing molds in order to achieve a long service life for the molds.

3. Adequate resistance to the effects of temperature

In order to maintain continuous production, the temperature of the mold will sometimes reach 200 ° C. Because this will cause a reduction in the mold's strength and hardness, the material used in the mold needs to have exceptional thermal stability. Carbide TC Drawing Dies have sufficient thermal stability, making them resistant to high temperatures.

4. Excellent processability

The manufacturing process for a cold extrusion mold takes a long time and requires a high level of accuracy. In most cases, casting, cutting, heat treatment, grinding, or some other form of fine finishing will need to be done. Therefore, the needs of production can only be satisfied by the materials that have a high degree of processability. The outstanding procedure of using carbide molds is going to be your best option.

The Safety Measures To Be Taken Along With The Routine Upkeep Of Tungsten Carbide Wire Drawing Dies

1. Make certain that the drawing machine is not unstable.

Each drawing drum and its over-line guides ought to be smooth and flexible, and their beating tolerance ought to be strictly controlled. In the event that the drum is located, the guide wheel will have a worn trench, and the polycrystalline diamond (PCD) wire drawing dies will need to be fixed as soon as possible.

2. An effective lubricant

It is essential to use a high-quality lubricant in order to maintain the surface quality of the wire and increase the useful life of the mold. In order to prevent contamination of the equipment hole, the lubrication index should be checked on a regular basis. Additionally, any copper powder or other impurities in the lubricant should be removed. If the lubrication isn't doing its job, it needs to be cleaned and replaced at the appropriate time.

3. an allotype that is reasonable

Reasonable allotype is used to ensure the surface quality of the wire, control the wire's size accuracy, and reduce the operating load and wear on the wire drawing drum. It is necessary to become familiar with the mechanical elongation of the equipment in order to draw wire using sliding wire drawing machines. The sliding coefficient is chosen in a reasonable manner, which is the first step in the process of fitting mold.

4. Make the necessary adjustments to the size in order to account for the compression angle

In addition, the surface reduction rate of each drawing as well as the material of the drawn wire have a strong correlation with the compression angle of the mold that each drawing was done on. The magnitude of the compression angle is modified in a manner that is suitable for the situation in accordance with the magnitude of the surface reduction rate.

5. The timely replacement of the drawing dies that were beginning to show their age

When the drawing die reaches the end of its service life, please replace it in a timely manner so that it can be repaired so that there is not an excessive amount of wire scrap.

In a variety of different industries, drawing is a common practice, and tungsten carbide wire are a common tool used.

It is one of the best mold materials because it has a high level of hardness, excellent thermal stability, high levels of durability, and a long life of service.
