Tungsten carbide bushings are mainly used for stamping and stretching. 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 tools is hundreds of times that of carbon steel.
The main function of cemented carbide bushing is that the bushing is a kind of part that protects the equipment. The use of bushings can effectively reduce the wear between the punch or bearing and the equipment, and achieve a guiding effect. In terms of stamping dies, the bushings of tungsten carbide are widely used because of their wear resistance and 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 and stainless steel parts. Due to the high frequency of use, it is easy to generate heat and wear the bushing, which will cause the punching needle to move, the product size error, and the product The appearance is poor.
With the increase of oil extraction, the shallow surface oil decreases. 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.
Cemented carbide bushing, as a wear-resistant part in petroleum machinery wells, has the properties of high hardness, good wear resistance, and high smoothness. It has become more and more widely used in modern society to meet the needs of daily use and special performance. Some companies use spray welding 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, but the cemented carbide bushing after spray welding needs to be turned to ensure the size of the drawing Requirements and accuracy requirements.
At present, 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 cemented carbide bushings. Although ceramic tools are suitable for processing high-hardness workpieces, they only Suitable for finishing processes with small margins. Therefore, the most suitable tool material for machining cemented carbide bushings is the c
