摘要： A pick-style tool that includes an elongate tool body (22) with an axially forward end (26) and an axially rearward end (24), and a hard insert (28) affixed to the tool body at the axially forward end is disclosed. The hard insert comprises a WC-cermet comprising tungsten carbide and about 5 wt.% to 27 wt.% Co-Ni-Fe-binder. The Co-Ni-Fe-binder is unique in that even when subjected to plastic deformation, the binder sustantially maintains its face centered cubic (fcc) crystal structure and avoids stress and/or strain induced transformations.

摘要： A cutting bit (10) including a conical nose (12) and an integral depending cylindrical shank (14). The conical nose (12) includes a tip (26) having a hard wear resistant insert (28) and a flange (24) positioned between the tip (26) and the shank (14) and having a diameter greater than the shank (14). The flange (24) has a planar underside (30) including at least one undercut (34) extending radially inward from the exterior peripheral surface of the flange (24) to provide in cooperation with the face (32) of a cutting bit block (20) a resistance surface for insertion of a tine of a cutting bit removal tool.

摘要： A semi-locking pick box assembly (10) comprises a pick holder (30), a hydraulic seal (40) and a closed pick box (50). The pick holder has a frusto conical shank (33) with a base (34) and the closed pick box (50) has a shank chamber (51), a piston chamber (52) and a hydraulic duct (54). The shank chamber (51) matches the shape of the frusto conical shank (33) so that the pick holder (30) can lockingly fasten to the closed pick box (50) when the pick holder and closed pick box are engaged. The piston chamber (52) communicates with the shank chamber (51) and houses the hydraulic seal (40) so as to form a hydraulic piston which can act on the base of the frusto conical shank. The hydraulic duct (54) communicates between the piston chamber (52) and externally of the closed pick box (50) so that hydraulic pressure can be applied via the hydraulic duct (54) to the hydraulic seal (40) to cause the pick holder (30), when lockingly engaging the closed pick box (50), to move axially and be released from the closed pick box (50).

摘要： A point attack bit has an enlarged head, an integral and coaxial shank extending from the base of the head, and a tip extending from the other end of the head and having a generally frustoconical end with an odd number of side faces disposed between the end and the head. The odd number of side faces create an unbalanced loading on the bit when it engages the surface to be mined, excavated or cut and cause the bit to rotate within a mounting block in which the shank is rotatably received to reduce the wear on and more evenly wear the bit. The faces may be generally flat or they may be arcuate providing a generally frustoconical tip. The tip is preferably a carbide insert operably connected to the head of the bit. In one form, the head is frustoconically shaped and has a smooth exterior. In a second form, the head has a construction similar to that of the tip and preferably has the same number of side faces as the tip with each face of the head and tip generally aligned.
摘要翻译：点攻击点具有扩大的头部，从头部的基部延伸的整体和同轴柄，以及从头部的另一端延伸并且具有大致截头圆锥端的尖端，其中奇数个侧面设置在末端和头。当钻头接合待开采，挖掘或切割的表面时，奇数的侧面会在钻头上产生不平衡的载荷，并使钻头在安装块内旋转，在该安装块内可转动地接收柄，以减少磨损并更均匀穿了一下面可以是大致平坦的，或者它们可以是弧形的，提供大致截头圆锥形的尖端。尖端优选地是可操作地连接到钻头头部的硬质合金刀片。在一种形式中，头部是截头圆锥形的并且具有光滑的外观。在第二种形式中，头具有类似于尖端的结构，并且优选地具有与尖端相同数量的侧面，头部和头部的每个面大致对齐。

摘要： A pick holder (110) is frictionally seated via a round cylindrical barrel (112) in a pick box of a continuous miner. A pick is in operation rotationally located in a bore (114). The bore (114), toward a rear thereof, has an internal, inwardly projecting screw thread (30). When the pick has been removed, the pick holder (110) is extracted from the pick box by screwing a screw threaded shank into the screw thread (30), and applying an extracting force via the shank and the interengaged screw threads to the pick holder (110).
