摘要:
An installation tool for a fastener of the “pull screw” type, comprising a breakable gripping element includes a body, a first sleeve movable axially and rotationally in the body that can drive the gripping element, a second sleeve movable axially in the body and immovable in rotation, and a driving device provided with a turning shaft. The shaft comprises a first free wheel for driving the first sleeve in rotation, a second free wheel, and a driving element positioned coaxially around the second free wheel. The driving element cooperates using a helical link with the second sleeve. The first free wheel drives the first sleeve in rotation in a first rotation direction of the shaft. The second free wheel brings the driving element in rotation in a second rotation direction of the shaft to move the second sleeve axially, allowing full setting in a single operating sequence.

A feed assembly for a foot-pedal operated riveter and a method of using the same is disclosed. The feed assembly includes a rivet stop that has a tip that separates a lowermost fastener from a second from lowermost fastener when the riveter is in a non-operational position. This rivet stop prevents fasteners from sliding down a raceway on the feed assembly. When the riveter is moved into an operational position, the rivet stop moves out of the way and permits the second from lowermost fastener to slide into position for subsequent installation. The rivet stop thus enables automatic reloading of the riveter during operation.
摘要:
A system and method for rivet setting comprising an anvil having an anvil face and a plunger having a sensor coupled to a control system that measures the distance between the anvil face and the work surface during the rivet setting process and stops the rivet driver when the driven rivet head achieves a desired head height above the work surface. In preferred embodiments, the control system also communicates the stage of the rivet driving cycle to the operators to expedite the rivet driving process.
摘要:
A fastener carrier for fasteners for use in a riveting system, said carrier comprising at least one holding zone and at least one release zone, wherein said holding zone holds a fastener in a stored position and said release zone releases said fastener from said carrier, said holding zone having a diameter smaller than said release zone.

A rivet gun has a barrel, a handle assembly, a cylinder and a seal ring assembly. The handle assembly is mounted under the barrel and has a hydraulic shaft and a handle mounted around the hydraulic shaft and having an annular shoulder. The cylinder has a top cover, an annular body and a bottom seat. The top cover is mounted under the handle and contacts the annular shoulder. A diameter of the top cover is larger than a diameter of the annular shoulder such that an outer periphery of the top cover protrudes radially out from an outer periphery of the annular shoulder instead of being covered by the annular shoulder. The annular body is mounted detachably on the top cover. The bottom seat is mounted detachably on the annular body. The rivet gun is allowed to change cylinders of different sizes or types.
摘要:
An apparatus for attaching rivets, buttons or the like to textiles or the like, having a plunger which performs the riveting stroke and whose upward and downward movement is controlled by the interaction of the top end of the plunger with a cam plate rotationally driven by an electric motor, the apparatus performing a sequence of attachments upon actuation of a switch or the like, the electric motor (39) running at a fixed preset angular velocity being stopped briefly in the top dead-center position of the plunger (24) by a braking device or the like in order to reduce the cycle frequency of the plunger stroke. To this end, the control unit switches off the drive motor (39) in the top dead-center position of the plunger for a preprogrammed time and switches it on again after the preprogrammed waiting time has expired and actuates a brake in particular during the waiting time.
摘要:
Apparatus for carrying out an operation on a mechanical workpiece which operation comprises at least one stroke, or relative movement, along a predetermined path, of at least two tool members (4,5) each being arranged on a tool carrying member (1,2). The mechanical workpiece is positioned between the tool members (4,5) and the tool carrying members (1,2) are approached to each other in a first part of said at least one stroke. At least one force transferring element is arranged to be inserted by means of a low force during said first part of said stroke into a position between at least one tool carrying member and an activation element for transferring a high force during a second part of said stroke between said activation element and said at least one tool carrying member.
摘要:
Although the conventional continuous riveting machine was able to use exclusively a special blind rivet having a longer core-stem than that of the standard type, the continuous riveting machine according to the present invention is able to use the standard blind rivet and also able to recover separately torn core rivet stems and a blind rivet-holding belt made of plastic material enabling the supply of blind rivets in series. When a lower piston 600 descends in a jaw cylinder 400, a nose piece 620 integrated in one piece with the lower piston 600 also descends while bending downwardly plastic upper and lower tabs of the blind rivet-holding belt, and holding the blind rivet. Torn-core-stems are absorbed and stored in a torn core rivet stems storing case installed on the upper portion of the jaw cylinder by applying vacuum air absorbing force generated in a vacuum ejector.
摘要:
A riveting tool of the kind having an elongate, headed, mandrel on which a plurality of tubular rivets are supported as a column, and which can be gripped and reciprocated relative to an abutment by reciprocable gripping jaws so as to draw the head of the mandrel through each rivet supported in turn by the abutment, and having a mechanism for feeding the column of rivets towards the head of the mandrel, has both the rivet feeding mechanism and the gripping of the mandrel by the jaws operated pneumatically, each respectively being under the control of a manually operable valve. In order to avoid the possibility of the feeding mechanism being actuated at a time when the mandrel is not gripped by the jaws, the valves are interengaged with a detent arranged to prevent opening of the valve which controls the rivet feeding mechanism when the valve which controls the jaws is closed.
摘要:
A self-drilling blind rivet comprising a rivet sleeve and an upsetting pin passing the rivet sleeve at least partly and projecting from one end of the rivet sleeve. A drill bit is attached to the other end of the rivet sleeve either directly on the sleeve or on one end of the upsetting pin.
