Explanation of the service life of the coupling sleeve

The service life of the brazing sleeve is determined by the quality of the brazing sleeve itself and scientific use. Early scrapping. Such as the reasonable selection of drill bit varieties and specifications, the matching of cemented carbide and rock properties, the matching of drill bit diameter and impact energy of rock drill, the correct disassembling and assembling of drill bits, and so on.

The service life of the coupling sleeve is determined by the quality of the coupling sleeve itself and scientific use. Early scrapping. Such as the reasonable selection of drill bit varieties and specifications, the matching of cemented carbide and rock properties, the matching of drill bit diameter and impact energy of rock drill, the correct disassembling and assembling of drill bits, and so on. Head, rock drilling process of drilling operations, the use of card drilling technology. It is imperative that the fully utilize the potential performance of the rock drill tool. Drill bits are subjected to very intense loads, mainly cyclic alternating loads, wear and corrosion, which dulls them during the drilling process. If the energy output from the drill is not used to break up ore and rock, but is reflected back to the cutting edge in the form of stress waves, the forces on the bit and the rest of the drill will deteriorate, resulting in abnormal damage to the bit. Then the stress on the drill bit and other parts of the drill will deteriorate, resulting in abnormal damage to the drill bit and a sharp decrease in drilling speed. Therefore, the study of reasonable grinding process and equipment is bound to become an important measure to extend the service life.

With the development of China's new rock drilling tools and the continuous improvement of the quality of the brazing sleeve, in the research and development of the drill bit for drilling very hard rocks, the advanced isostatic pressure technology is used to strengthen the processing, and the structure and shape of the drill bit performance parameters are reasonably designed. The brazing sleeve body is made of good Taigin steel, developed into K610 hard alloy sheet, copper-based brazing material and dehydration flux, and applied with new welding technology to make the φ40 drill bit more durable. With the new welding technology, the four kinds of drill bits of φ40 and φ60 can withstand uniaxial compression, and the service life of very hard iron ore chiseling of 463MPa strength reaches 12.6-14.3m/piece, which is more than the level of similar foreign products. Domestic horseshoe, three-edged, five-tooth series of cemented carbide drill bits have been successfully developed and have entered the international market. Brazing bushings are not only exported to The brazing bushings are not only exported to the third world countries in bulk, but also exported to the United States and Western Europe. China's rock drilling tools to cover more and more, China's rock drilling tools and the world's advanced level of the gap is narrowing, began to be concerned by the international market, the competitiveness of brand-name products. Some of the domestic brazing sets of enterprises in the appropriate capital investment, strengthen the training of the workforce and the new product Some domestic brazing sleeve enterprises have made necessary articles in appropriate capital investment, strengthening staff training and new product development and stockpiling. The brazing sleeve products have a certain degree of popularity at home and abroad, although the price of their products is relatively high - some, but their sales are still good.

To produce high-quality brazing bush products, it is necessary to have good raw materials, advanced production technology and equipment, high-quality staff and good after-sales service. It is not enough to make a horse run fast if a person is bold and prolific but does not concentrate on feeding the horse. Strength of the company should be in the technology and equipment to make appropriate investment, do not always Do not always follow the trend, just imitation or plagiarism. Cultivate their own high-quality workforce, need to treat it as a business, to build a century-old store. We need to make our brazing products stronger and more precise, but at the same time, we should not be greedy for foreign countries and do whatever we want to do, otherwise nothing will be done well.
