Carbide Drill Bit Shank Adapter Montabert HC80 T45-490 For Coal Mining
Rock drilling tools manufacturer Prodrill produces shank adapters/striking bar for most models of current prevailing rock drill machines. All our shank adaptors are carburized, CNC manufactured, and made from premium steel. Thus ensure them with superior toughness and anti-fatigue strength to meet the most demanding drilling conditions. Moreover, all shanks could be produced with ether male or female threads if there is actually necessary.
Male shank adapters/striking bar are generally better suited for drifting, tunneling and extension applications where high bending stresses are present. While female shank adapters are used when the drilling space is limited and the total feed length is important, for example underground roof bolting.
The task of the shank adapter/striking bar is to transmit rotation torque, feed force, impact energy and flushing medium to the drill string (extension drill rods, drifting drill steels).
The shank adapters/striking bar from ProDrill are there fore designed to with stand the high impact power of modern rock drills and made from specially selected material which also is hardened through cauterizing. Around 300 different shank adapters suitable for different rock drills are currently available from Atlas Copco series drifters, Tam rock series drifters, Garden Diver series drifters etc.
Two flushing options of shank adapters: internal or external
— Internal flushing uses a water tube that fits through the center of the drill and into an o-ring seal in the end of the shank, to transfer flushing into the drill string
— External flushing, holes or a slot are required in the side of the shank adapter.These line up between seals inside the front head or water box of the rock drill, when the shank is installed. Flushing medium is supplied directly to this device and is introduced into the drill string through the shank
— External flushing is considered superior to internal flushing, as greater volumes of flushing agent can be delivered with less risk of leakage and hammer damage from water
The shanks for hydraulic drills and some pneumatic drills have external or front head flushing. Hydraulic shanks generally have at least 5 to 14-spline configuration, Pneumatic shanks tend to have internal or through flushing and can generally be identified by their lugs or 4-spline configuration.
Used for mine operation, select high quality alloy steel as raw material, through the whole carburizing treatment. Use special CNC machine tool processing equipment and processing process to ensure the tail details, internal and side water hole machining quality. After uniform heat treatment, the brazing tail is straightened with precision instruments to ensure the straightness and anti-manic property of the brazing tail.
The function of the bit tail is to directly bear the impact work and torque of the drill.
The specification and hardness of the bit tail have great influence on the drilling speed, the life of the drill and the drill bit. Therefore, the drill tail should be of appropriate length, with smooth and clean end face, vertical section and axis, and consistent with the drill sleeve of the rock drill (the gap shall not be greater than 0.5mm). Brazing tail hardness to be appropriate, too soft brazing tail life is short, too hard piston is vulnerable to injury, generally brazing tail hardness should be slightly lower than the piston hardness, quenching hardness HRC=38~45 is appropriate.
