There is provided an automated rivet apparatus for installing a semi-tubular fastener rivet. The apparatus includes a numerical control (NC) drilling and riveting machine and a controller. The NC drilling and riveting machine includes a lower head having a lower pressure bushing, a lower drill spindle, and a lower anvil to apply an upset force to a tail portion of the semi-tubular fastener rivet. The NC drilling and riveting machine further includes an upper head having an upper pressure bushing, an upper drill spindle, and an upper anvil that holds the semi-tubular fastener rivet to insert the semi-tubular fastener rivet in a rivet-receiving hole. The lower drill spindle countersinks the rivet-receiving hole from a lower side of a workpiece. The controller directs movement of a nose of the lower anvil to apply the upset force and form a predetermined flare contour in the tail portion within a lower countersink.

An apparatus, system, and method for removing and installing slasher teeth in a saw are provided. The apparatus has a first body and a second body having a space formed therebetween, wherein a slasher tooth is positionable within the space. At least one locator pin is connected to at least one of the first and second body, the at least one locator pin contactable to the slasher tooth to locate the first and second body relative to the slasher tooth. At least one engagement device is positioned on one or both of the first and second bodies, the at least one engageable device being actuatable, whereby actuation of the at least one engagement device moves it relative to the first and second bodies and into the space where the at least one engagement device contacts a rivet positioned between the slasher tooth and a saw body.

A method for removing a blind rivet includes a workpiece arrangement having first and second surfaces and a connecting hole. A blind rivet is fixed in the hole and has a shell and screw through the shell extending coaxially along a common center axis, the shell having a shell head portion, straight portion, deformation portion and threaded portion having an internal thread. The straight portion is in the hole and the deformation portion and the threaded portion protrude out of the hole, the screw having a screw head portion and pin portion having an external thread. The screw is in the shell such that the deformation portion of the shell is deformed where the outside diameter of the deformed deformation portion is larger than the diameter of the hole. The shell is cut in the region of the thread portion and/or the deformation portion, and the blind rivet is removed from the hole.

An apparatus, system, and method for withdrawing slasher teeth from a slasher saw are provided. The apparatus has a handle, and a forked portion is connected to one end of the handle. A gap is formed between two prongs of the forked portion. A floating shank positioner is positioned at least partially within the gap. At least one common hole is formed through the two prongs of the forked portion. When the slasher tooth is connected to the at least one common hole, pivoting of the handle removes the slasher tooth from the pocket of the saw.

An automatic riveting gun and a method of operating same are disclosed, the automatic riveting gun includes a gun body including a rivet cavity, a front cavity, and a main cavity; a rivet clamping assembly is disposed on the gun body adjacent to the rivet cavity; a front-dynamic structure is movably disposed in the rivet cavity and the front cavity and a main-dynamic structure is movably disposed in the front cavity and the main cavity. The front-dynamic structure includes a claw sleeve. A claw mechanism is movably disposed in the main-dynamic structure. A front elastic element provides an elastic force to the claw mechanism and a main elastic element provides an elastic force to the main-dynamic structure.

The present invention relates to a cutting device for use in cutting a collar which is mounted on a bolt in half, the cutting device comprising: ⋅ a mouth (16) for receiving the portion of the collar (28) to be cut; ⋅ a pair of jaws (17a, 17b) diametrically opposite one another and located within the mouth (16), each jaw (17a, 17b) being provided with a cutting blade (18), ⋅ a driver (22) for moving at least one jaw (17a) relative to the other (17b) such that the collar (28) can be cut in half by the action of the jaws (17a, 17b) moving towards one another, and ⋅ a guard (15) which, in use, prevents the cutting blade (18) from protruding beyond the mouth (16) and damaging a surface adjacent to the collar (28) to be cut in half.
