The present invention provides a rivet gun including a first handle, a second handle, a transmission mechanism, and a clamping-pulling mechanism. The first handle is fixedly connected or integrated with a housing limiting the clamping-pulling mechanism, and the second handle is rotatable around a first fixed shaft relative to the first handle; the clamping-pulling mechanism includes a pull rod with gear grooves thereon; the transmission mechanism includes a gear member with a gear end rotatable around a second fixed shaft, the gear end of the gear member being configured to engage with the gear grooves on the pull rod; and the second handle is connected to the transmission mechanism, and configured to drive the gear member of the transmission mechanism to rotate when the second handle is rotated and opened relative to the first handle such that the gear member pushes the pull rod forward by engagement between the gear end and the gear grooves, and to drive the gear member of the transmission to rotate when the second handle is rotated and closed relative to the first handle such that the gear end of the gear member pulls the pull rod backward by engagement between the gear end and the gear grooves.

A rivet joining method, etc., suitable for providing rivet joining using sound vibration and/or ultrasound vibration is provided. Joining is provided in a state in which a rivet is inserted into a hole formed in a base member. The base member includes a first member and a second member. The hole is formed such that it passes through at least one of the members. The rivet is formed of a metal material and has a head portion and a body portion. A vibration processing part applies sound vibration and/or ultrasound vibration to the rivet in a state in which at least its body portion is inserted into the hole, so as to join the rivet and the inner face of the hole.

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.

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.

A rivet feeding system having a hopper, an inclined rail, and a fastening assembly is disclosed. The hopper accommodates a plurality of rivets, each having a head and a tail, in a barrel rotatably mounted to a stationary back. The hopper permits a single rivet to exit the hopper at a time and the exiting rivets are received by the inclined rail. The inclined rail has a channel defined by two sidewalls and the channel is sized to accommodate the rivet tail and the two sidewalls are positioned to support the rivet head. The inclined rail is positioned to receive rivets in a first orientation and to deliver rivets to the fastening assembly in a second orientation that is distinct from the first orientation. The fastening assembly includes a stationary anvil positioned below a moveable punch and a pair of pivotable jaws positioned between the anvil and the moveable punch.

A method is disclosed for inserting a nail into at least one component part, the nail having a nail head, a nail shank and a nail tip. The method includes (i) arranging the at least one component part, (ii) positioning the nail, and (iii) driving-in the nail. A force is applied to the nail in the direction of the component part, such that it is pressed into the at least one component part. In addition to the application of force, vibrations are coupled into the nail, and a multipart nail is used.
