tungsten carbide bushing bearing is mainly used for stamping die layer and drawing layer. Cemented carbide tools are commonly used as tool materials, such as lathe tools, turning tools, planers, twist drills, boring tools, etc., for drilling pig iron, rare metals, plastics, chemical fibers, high-purity graphite, laminated glass, marble and General stainless carbide plates can also be used to drill materials that are difficult to produce and process, such as heat-resistant carbide, stainless carbide, medium carbon carbide, and alloy carbide. Nowadays, the cutting amount of the new-style carbide tool CNC blade is equivalent to hundreds of times that of alloy carbide.
The key function of the hard alloy tungsten carbide bushing bearing depends on that the bushing bearing is a kind of component for the maintenance of machinery and equipment. The application of tungsten carbide bushing bearing can reasonably reduce the damage between the punching needle or rolling bearing and the machinery and equipment, and Achieve a oriented effect. At the level of hardware molds, tungsten carbide shaft sleeves are widely used due to wear resistance and good smoothness, and do not need to be replaced frequently, thereby achieving higher utilization of machinery and equipment and staff.
The hard alloy tungsten carbide bushing bearing is on the drawing layer, mainly the drawing of some copper parts and stainless carbide plate parts. Due to the high frequency of application, it is very easy to get hot, causing damage to the shaft sleeve and causing the punching needle to move. The specification deviation of the product, and the appearance of the product is not good.
With the increase in crude oil production, the crude oil in the shallow surface layer decreases. In order to better ensure the demand for crude oil, everyone is slowly developing the trend of large deep water wells and highly inclined wells, but the difficulty coefficient of extracting crude oil is slowly increasing, so The parts and components used for extracting crude oil are required to have excellent wear resistance, corrosion resistance or impact resistance.
Hard alloy tungsten carbide bushing bearings are used as wear-resistant components in chemical machinery wells. They have high strength, good wear resistance and high smoothness. The use in modern society has become more and more common, considering daily necessities and unique characteristics Must. Some companies choose spray welding processing technology to improve the wear resistance and service life of hard alloy tungsten carbide bushing bearings.
The strength of the spray-welded hard alloy tungsten carbide bushing bearing reaches HRC60, and the wear resistance is stronger. The application regulations in the field of chemical machinery can be considered, but the hard alloy tungsten carbide bushing bearing after spray welding needs to be milled. It is convenient to ensure the size and precision requirements of the drawings.
At this stage, the common tool materials include cemented carbide tool CNC blades, ceramic tools and cubic boron nitride CNC blades, but the strength of the cemented carbide tungsten carbide bushing bearings can remove the cemented carbide tool CNC blades, ceramic tools Although it is suitable for the production and processing of high-toughness product workpieces, it is only suitable for small-volume deep processing processes. Therefore, the most suitable tool material for the production and processing of hard alloy tungsten carbide bushing bearings at this stage is none other than cubic boron nitride CNC blades.
