This kind of product is one of the most widely produced drilling tools in China, and it is also a rock drilling tool that is widely used in domestic underground mines and construction projects.
Compared with the integral drill, there is energy loss at the cone connection of the cone connection drill rod. According to the information, the energy loss of the shock stress wave after one round trip in the rod body is about 5% higher than that of the whole drill.
At the same time, the cone connection part of the drill rod is the weak link in the drill tool group. If it is processed or used improperly, the destructiveness of the drill tool will be increased.
However, a cone-connected drill rod can be equipped with multiple drill bits to drill holes of different diameters; the drill rod will not be scrapped after the drill bits are worn, the maintenance is simple, and the price is low; the consumption of drilling tools per meter is low, etc. .
Since the 1970s, domestic production enterprises and scientific research units have carried out a series of researches on cone connecting drill rods. Great progress has been made in materials, forging and brazing technology, equipment, heat treatment and working load mechanism, and damage analysis.
