H22 drill rod manufacturers believe that with the continuous progress and development of my country's mining industry, underground mining enterprises in various parts of my country are showing a trend of large-scale, mechanized, information-based and safe, and at the same time, they are also to meet the overall requirements of scale, low cost, high safety and environmental protection.H22 drill rod manufacturers believe that the drill head chain of rock drilling tools is a relatively backward link in the entire rock drilling system. The entire drill head system includes drill tail, connecting sleeve, drill rod and drill head. The entire drill head system requires accurate processing technology and ideal processing technology, so that the entire system can have better quality and rock drilling performance.The entire system, including drill head, rock drill and drill tool system, needs to be moderately adjusted according to special drilling conditions and applications.The entire drill tool system needs to meet the following requirements:
1. Characteristics of high-speed drillingH22 drill rod manufacturers believe that modern hydraulic rock drills provide powerful power for rock drilling tools. During the working process, the drill head of the rock drilling tool is subjected to strong compressive stress, tensile stress, thread wear, frictional heat and rock erosion.2. Required characteristics of drill tool materialsH22 drill rod manufacturers believe that in the above complex situations, rock drilling drill tool materials are required to have four characteristics(1) Robustness In order to achieve less energy loss and ideal verticality of drilling holes, the drill tool material is required to have good robustness and reasonable drill tool size.(2) Fatigue strength. H22 drill rod manufacturers believe that the drill tool system is subjected to large compressive stress and high-frequency tensile stress during operation, which requires the drill head to have high fatigue resistance.(3) Working under high-intensity and high-power rock drills, the drill tool system is required to have high strength to greatly reduce the possibility of drill tool breakage.(4) High wear resistance For rock drilling tools, high wear resistance can ensure a longer life of the thread, especially for the alloy part of the drill head. The above four characteristics of rock drilling tools are not positive, but also negative.H22 drill rod manufacturers believe that when choosing drill rods, we need to consider many factors, first of all, we need to look at the material, shape and size of the drill rod. After knowing these basic factors, we can know whether it is suitable for making drill tools. At the same time, we should also consider the power of the rock drill, power and rock hardness. It is closely related to how we choose the drill rod.H22 drill rod manufacturers believe that if the rock hardness is high, we should choose a high-power rock drill. At the same time, we should choose a good quality drill rod. If there is a problem with the drill rod, the drill cannot work properly. In addition, when choosing a drill rod, we must first understand the diameter of the drill. The depth of the rock is also a factor that cannot be ignored. In general, under the condition of meeting the drilling requirements, we should choose a drill rod with an interface consistent with the cross section of the rock drill.
