It is installed at the joint of matching drill rods during drilling operations and plays a critical role in connecting multiple drill rods on the same axis. Through threaded connections, the sleeve effectively transmits the impact energy generated by the rock drilling machine, allowing efficient drilling of rock holes.<\/p>\n\n<h3 data-section-id=\"2hw79h\" data-start=\"535\" data-end=\"557\">Working Function<\/h3>\n<p data-start=\"558\" data-end=\"1026\">During the drilling process, the connection sleeve connects drill rods or tail drill rods and ensures stable transmission of power and stress waves. It bears multiple types of loads, including axial tension and compression, bending, torsion, contact, and friction stress. Because of these complex working conditions, selecting appropriate materials and optimizing the geometric structure and manufacturing process are essential for ensuring performance and durability.<\/p>\n<h3 data-section-id=\"oq0xba\" data-start=\"1033\" data-end=\"1065\">Material and Manufacturing<\/h3>\n<p data-start=\"1066\" data-end=\"1295\">We specialize in the production and manufacturing of blast furnace drill rods and blast furnace opening equipment.
