The rock drilling tool is a slender rod system composed of drill bits, drill rods, shank tails and other components. The main tool of rock.
During the use of the drilling tool products, they are subject to severe wear and tear of rock ores, high-pressure water or airflow, and erosion and corrosion of mine water. Impact energy, high-speed impact on rock under tension, compression, bending and torsional stress conditions, and finally drill holes in the rock for placing explosives. Due to the use conditions and complex stress conditions, the drill products often fail in the form of stress corrosion fatigue fracture, and the service life is usually ten minutes to dozens of hours. It can be said that rock drilling tools are the necessary consumable tools in the basic industry with relatively severe stress conditions, short service life and high technical content among all steel tools at present.
At present, my country's mining engineering sector consumes about 120,000 tons of brazing steel and brazing tools and more than 50 million pieces, worth nearly 4.5 billion yuan. The foreign rock drilling tool market has an annual capacity of nearly 10 billion US dollars. Due to various historical reasons and the backwardness of drilling tool technology and production management in China, compared with the products of foreign drilling steel and drilling tool companies, domestic rock drilling tool products have many problems in terms of performance, product quality, variety and specifications. a certain gap. Therefore, paying attention to strengthening the research and development of domestic brazing steel and drilling tools will further promote the development of my country's brazing steel and drilling tools industry.
The importance of research and development of drilling tools and precautions for the use of drill pipes! With a drill bit, there will definitely be its "brother" drill pipe. We can easily understand what a drill pipe is literally. Let's take a good look at the precautions for the use of drill pipe!
1. When using for a drilling and excavation, you should first "grind new buttons", which includes, first apply the threaded oil for technological innovation, and then use the drilling rig to fully tighten it. After opening the domestic demand for the buttons, apply the threaded buttons. The oil is turned on again, and this is repeated three times to avoid new wear and buckle.
2. Keep the drill pipe in a straight line between the ground and the ground as much as possible, so as to avoid stress on the side of the thread and cause unnecessary wear and tear, and even skip the drill pipe. Pay attention to the anchoring of the drilling rig to avoid stress during construction. Movement is very important.
3. When using a new drill pipe, it should be determined that the thread of the front section of the drill bit (protecting the shaft head) is also close to the new one. A bad thread can easily damage the thread of the new drill pipe, resulting in water leakage and snapping. , loose, etc.
