Tungsten Carbide Punches
Tungsten carbide punches last longer than their steel counterparts. This enables them to be used repeatedly and reduces the time spent on changing tools.
The investigated tools were made from tool steel W360 with cryptoacicular martensite. The analyzed microstructures of the calotte peak and the calotte slope were examined using light microscopy.
Hardness
Carbide punches are designed to be extremely hard so that they can withstand the pressure required to perform the desired task. This makes them ideal for use in applications that require a durable tool, such as punching, stamping, and forming materials. The high hardness of these tools also helps to ensure that they remain sharp and dimensionally accurate over time, which can reduce downtime and eliminate the need for frequent replacements.
Tungsten carbide is an extremely hard material that can withstand high levels of friction and stress, making it ideal for use in punches and dies. It has a higher Rockwell hardness than steel and a compressive yield strength that is greater than metal. Because of this, tungsten carbide punches can be used in demanding applications such as stamping and forming metals.
Compared to a punch made from regular tool steel, a tungsten carbide punch will last much longer and will be less likely to wear out or become damaged during the stamping process. This can help to improve production efficiency by reducing the amount of downtime that is necessary to replace worn-out tools.
Tungsten carbide punches can be manufactured from a variety of different materials, depending on the specific application for which they are being used. These punches are often coated with a protective layer to protect them from damage and corrosion. They can also be finished with a range of surface treatments, which can help to further enhance their durability and performance.
Durability
Tungsten Carbide Punches are extremely durable, which reduces downtime and maintenance costs. They also last up to 40 times longer than comparable steel wear parts, saving your company money and improving productivity.
Due to their rigidity and unparalleled strength, tungsten carbide punches are ideal for applications in which they’re frequently in contact with abrasive materials. In addition, they can be made with a wide variety of surface treatments and coatings, increasing their durability even further.
In order to identify the factors that contribute to the low durability of the tool, microscopic observations were performed on the microstructures of punches tungsten carbide punches which worked over 400 forgings. Light microscopy and SEM were used for this purpose.
The results showed that the main cause of low tool durability is the high nickel and chromium content in the 1.2365 tool steel used for the forging charge. This high content increases adhesion between the punch and the forging material, and this causes abrasive wear of the calotte base. In addition, the normal stresses on the calotte surface during forging reach high values (locally reaching 1000 MPa) and can lead to plastic deformations of the punch. This can, in turn, lead to the formation of cracks near the calotte base. The result is a gradual loss of the height of the calotte.
Heat Resistance
Tungsten carbide punches have excellent heat resistance, making them a great choice for a variety of applications. They can withstand high temperatures and abrasions without losing their rigidity or strength, and they can withstand a lot of pressure. In addition, they can last longer than punches made of traditional steel, reducing the amount of time and money spent on replacing them.
Unlike other metals, cemented carbide has good compressive strength. This physical property makes it easier to punch holes in hard materials like titanium alloys. Carbide also has very good wear resistance and can withstand the impact of cutting, punching, and forming.
Tungsten carbide is consolidated using the evaporation-deposition-reflux system (EDRS). This process can be used to make very large parts that would otherwise be impossible to produce. The EDRS process is similar to the SPS process, but it uses higher voltages to achieve a densification rate that is up to two times faster than the SPS process.
The EDRS process also uses more powder than SPS, which allows the material to reach a density of 95% in less than 10 seconds. The sintering rate can be controlled by the pressure, electrical current, and pellet thickness. A higher sintering rate results in a more dense pure tungsten carbide punches custom tungsten carbide product, which leads to better mechanical properties and lower manufacturing costs.
Resistance to Corrosion
Carbide punches are made from a hard metal that is resistant to corrosion and has a long lifespan. These attributes make them ideal for precision machining and metal stamping applications where the punches will come into contact with abrasive materials. Carbide is twice as hard as steel and has a high level of wear resistance, which translates to less downtime for maintenance and replacements.
Carbides also have the benefit of being strong against compressive stress, making them suitable for use in demanding punching applications. They are however weak against tensile stress, which makes them less suitable for shearing holes in hard and thick materials. Carbide dies and punches are typically constructed of tungsten carbide, as it is the most durable material for such applications.
The strength of a punch is directly related to its design and specifications. The best way to determine the appropriate size and shape for a carbide punch is by consulting with experienced professionals. This can help manufacturers achieve better results and reduce production time.
Depending on the application, a carbide punch may be coated or treated to improve its performance or durability. This can include coatings such as DLC, CrN, TIN and TiALN, among others. These coatings can significantly increase the longevity of a carbide punch and extend its life. In addition, they can also be used to improve the quality of finished parts.
