The purpose of the shank adapter: The force state and performance requirements of the shank adapter of the hydraulic rock drill. Choose 23CrNi3Mo for carburizing, quenching and tempering, and develop a product that can replace the imported shank adapter, and its performance can reach similar foreign products. Long-life hydraulic rock drill shank provides a new method.
Gaea rock's blast furnace opener shank is mainly used for opener operation. Alloy steel is selected as the raw material and has been carburized as a whole. The CNC machine tool processing equipment and processing process used to ensure the quality of the tail details, internal water holes and side water holes. The shank adapter is uniformly heat-treated and scientifically straightened with an instrument to ensure the shank adapter is straight and anti-irritating.
The scope of application of the shank adapter: The shank adapter is suitable for mining operations, and high-quality carbon structural steel is selected as the raw material and undergoes the overall high-frequency quenching treatment. The adopted numerical control milling machine production line equipment and production processing production process ensure the production and processing quality of the key links at the tail, internal water holes and side water holes. The shank has undergone uniform heat treatment and is scientifically adjusted with instruments and equipment to ensure the shank's verticality and anti-irritability. The function of the shank adapter is to immediately take on the destructive work and torque of the rock drill.
The shoulder-type shank shank is hexagonal in cross-section with an inscribed circle diameter. It is manufactured by forging technology and is used for light rock drills. The shank type shank is used for the inner-rotating medium-sized rail type rock drill, and the front rod diameter has two kinds of 25mm and 32mm. Spline shank is often used in heavy-duty rail-type external rotary rock drills with larger torque, and the drill rod diameter is more than 38 mm. It is often used for manufacturing by mechanical processing methods.
