Tungsten steel bushings are mainly used for stamping and drawing. Cemented carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for cutting Hard-to-process materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc. The cutting speed of the new cemented carbide tool is hundreds of times that of carbon steel.
The main function of the cemented carbide bushing is that the bushing is a kind of part that protects the equipment. The use of the bushing can effectively reduce the wear between the punch or the bearing and the equipment, and achieve a guiding effect. In terms of stamping dies, the bushings of tungsten steel are widely used because they are wear-resistant and have a good finish, so they do not need to be replaced frequently, so as to achieve a higher utilization rate of equipment and personnel.
In terms of stretching of cemented carbide bushings, it is mainly the stretching of some copper parts and stainless steel parts. Because of the high frequency of use, it is easy to generate heat and wear the bushing, which will cause the punching needle to move, the size error of the product, and the product The appearance is poor.
With the increase in oil extraction, the shallow surface oil is reduced. In order to ensure the use of oil, people gradually develop into large and deep wells and highly deviated wells. However, the difficulty of extracting oil is gradually increasing. Therefore, the parts and components required for oil extraction have good requirements. The wear resistance, corrosion resistance or impact resistance etc.
As a wear-resistant part in petroleum machinery wells, cemented carbide bushings have the properties of high hardness, good wear resistance, and high finish. The application in modern society has become more and more extensive, meeting the needs of daily use and special performance. Some companies use spray welding technology to improve the durability and service life of cemented carbide bushings.
The hardness of the spray-welded cemented carbide bushing can reach HRC60, and the wear resistance is better, which can meet the requirements of the petroleum machinery industry. However, the spray-welded cemented carbide bushing needs to be turned to ensure the size of the drawing. Requirements and accuracy requirements.
Common tool materials include cemented carbide tools, ceramic tools and cubic boron nitride tools, but cemented carbide tools can be excluded from the hardness of the cemented carbide bushings. Although ceramic tools are suitable for processing high-hardness workpieces, they are only suitable for small The remaining finishing process.
