摘要： A quick change tool holder having a cutting head on which a cutting member is attached for attachment to a shank. A lockpin/locknut arrangement provides for quick and safe removal of the cutting head from the shank. The lockpin has radial projections that rotate in response to manual rotation of the lockpin in and out of recesses contained in the opening of the locknut. The lockpin is secured within a bore in the cutting head and extends out of that bore into a bore in the shank in which bore the locknut is secured. A spring and plunger combination is located in the bore of the shank in order to urge the cutting head away from the shank when the radial projections are not within the recesses of the locknut. The shank and the cutting head have corresponding mating teeth in order to prevent rotation of the cutting head relative to the shank when the cutting head and shank are attached.

摘要： The present invention is particularly, but not exclusively, useful for reducing wear of component parts of impact crushers caused by earth aggregate flows during operation of impact crushers. The present invention includes a stepped central feed cone that allows for cylindrical carbide rods to be press fit therein to reduce wear. The downward steps of the stepped cone urge material fed to the stepped cone outwardly to the table. The top surface of a first rod inserted into a first bore formed in the impeller housing extends a distance beyond the bottom of a second bore on the next step up. The first rod protects the housing material forming the second bore from being washed out by material flow. In one embodiment, the impeller shoes have a geometric shape that reduces excessive normal forces and accompanying high friction of the material against the shoe. The reduction in high friction significantly reduces the wear rate.

摘要： A superhard filler hardmetal having a superhard material filler, binder metal or matrix and in some instances at least a first hard component is disclosed. The superhard filler hardmetal has a porosity rating of substantially A06, B00, C00 or better and may be essentially pore free, i.e., A00, B00, C00. The superhard filler hardmetal is formed by mechanically mixing a superhard material, in some instances at least a first hard component and a binder metal or matrix precursor, shaping the mixture into a green body and consolidating the green body at a preselected temperature, superatmospheric pressure and time at temperature and time at superatmospheric pressure sufficient to form the superhard filler hardmetal. The consolidation preferably occurs without the formation of a liquid in the body and at least a portion of the time at superatmospheric pressure is at the preselected temperature. Diamond filler and boron nitride filler are examples of superhard materials usable as filler. The diamond filler may be coated to prevent its degradation during consolidation and use. Boron nitride filler optionally may be coated.

摘要： A nozzle assembly for use in a drill bit includes a nozzle body having a nozzle oriented at an angle to the longitudinal axis of the nozzle body and a positioning ring that is rotationally and axially locked to the nozzle body. The nozzle body includes a plurality of facets extending between a pair of retention surfaces. The positioning ring has a plurality of teeth and is operatively disposed between the retention surfaces to axially retain the ring on the nozzle body. When positioned between the retention surfaces, the teeth engage the facets to rotationally lock the ring to the nozzle body. The positioning ring may have a longitudinal split, to allow the ring to ratchet relative to the nozzle body, and a pair of spanner-receiving apertures. In operation, the ring is coupled to the nozzle body and the resultant assembly is coupled to the drill bit. Any misalignment is noted and the assembly is removed from the drill bit. A spanner wrench may be used to rotate the ring relative to the nozzle body to compensate for the misalignment. The assembly is then recoupled to the drill bit with the nozzle in the preferred orientation.
