Under normal circumstances, the hardness of tungsten carbide pallets used in the production of bolts, nuts and screws should be between HRA81.5-83.
Carbide is usually made of tungsten-cobalt alloy and has the characteristics of high hardness, high wear resistance and high strength. Choosing the appropriate hardness can ensure the service life and strength of bolts, nuts and screws.
When the hardness of Tungsten carbide dies is too high, although it has good wear resistance, it may lead to poor coordination between the thread and the bolt rod or nut, which may easily lead to tooth-biting, thereby causing the thread to fail.
On the other hand, if the hardness of the tungsten carbide cold heading dies is too low, it may not be able to meet the high strength and wear resistance requirements required by bolts, nuts and screws during use.
Therefore, choose the appropriate hardness based on factors such as the target application, working environment, and material properties to obtain optimal performance and longevity.
To ensure the longest life of your tungsten carbide molds, here are some suggestions:
- Reasonable selection of materials: Choose carbide materials with good quality and suitable for specific working conditions. Ensure it has high hardness, high wear resistance, good toughness and crack resistance.
- Proper heat treatment: Carbide molds require appropriate heat treatment during the manufacturing process to improve their hardness and wear resistance. A proper heat treatment process can enhance the overall performance of the mold and extend its service life.
- Strictly control the usage parameters: According to the specific working conditions and usage requirements, strictly control the usage parameters of the mold, such as cutting speed, feed speed and cutting depth, etc., to ensure that the mold works normally within the tolerable range.
- Regular maintenance and upkeep: Perform regular maintenance and upkeep on carbide molds, including cleaning, lubrication and inspection. Remove impurities in the cutting fluid in a timely manner, maintain the cleanliness and lubrication effect of the cutting fluid, check the mold surface for damage or wear, and repair or replace it if necessary.
- Use high-quality cutting fluid: Choosing a good-quality cutting fluid can provide good tungsten carbide pallets price cooling and lubrication effects, reducing the possibility of mold wear and damage.
- Avoid overload: Arrange the workload reasonably to avoid overloading the mold. Appropriate cutting parameters and working conditions should be selected according to the carbide pellets price design and use requirements of the mold to avoid excessive wear and fatigue fracture.
- Timely repair and replacement carbide factory China: Once damage, wear or cracks are found on the surface of the tungsten carbide pellets mold, it should be repaired or replaced in time to avoid greater damage caused by continued use.
In short, to maximize the service life of cemented carbide molds, it is necessary to reasonably select materials, control usage parameters, perform regular maintenance and repairs, and repair or replace damaged zhuzhou carbide factory molds in a timely manner.
