Description
technical field [0001] The invention relates to the technical field of special mine equipment, in particular to a shank used for special mine equipment and a production process thereof. Background technique [0002] The drill rod of the rock drilling tool is the part that bears the impact and torque of the rock drill. It should have high toughness and no plastic deformation. The drill tail can be a part of the drill, or it can be made into an independent tail rod. The drill tail is mainly used in mines. For operation, high-quality alloy steel is selected as the raw material. Commonly used drill tails include drill shoulder (flange) type, drill lug (lug) type and spline type. 22mm and 25mm, length 108mm and 159mm, manufactured by forging process, used for light rock drills, lug-type shanks are used for internal rotary medium-sized guide rail rock drills, drill rod diameters are 25mm and 32mm, spline-type shanks are often used for Heavy-duty guide rail type external rotary ro...
