The Shank Adapter serves as a crucial component in rock drilling tools, tasked with directly withstanding the intense impacts and torsion generated by the rock drill during operation. It plays a pivotal role in transmitting the impact energy from the piston movement at the tail end of the drill to the drill rod and ultimately to the drill bit for effective rock drilling. Operating within the inner hole of the shank, it is exposed to mineral water corrosion, given the erosive nature of fast-flowing water and the humid conditions prevalent in mining and rock drilling environments.
To meet the demanding working conditions and performance criteria of Shank Adapters, the core material must exhibit not only exceptional toughness but also sufficient strength to endure high-impact contact fatigue. Additionally, considering the unique and intricate shape of the shank, material selection must account for the bending fatigue strength, necessitating a material with adequate hardenability. The shank, being a key element in hydraulic rock drills, thus demands a material with a balanced combination of toughness, strength, and hardenability to ensure optimal performance and durability.
Hydraulic rock drills typically operate at working pressures around 20Mpa, occasionally reaching as high as 25Mpa, with an impressive frequency of 3000-4000 impacts per minute. Consequently, the shank operates in conditions characterized by high speed, frequency, and robust impact, making it a pivotal component in hydraulic rock drill functionality.
In the demanding world of rock drilling, every connection counts. A single weak link can lead to equipment failure, costly downtime, and safety hazards. That’s why drilling professionals around the globe choose the Shank Adapter PR YH—a high-performance connector designed for precision, reliability, and longevity in harsh drilling environments.
