Abstract: A mandrel collector includes a case body and an end plate. The case body has a connecting end for being connected to a rivet gun. The end plate is engaged with the case body and is opposite to the connecting end. The end plate has at least one receiving hole, wherein a hole section of the receiving hole is a hexagonal hole with six walls. The walls include three first walls and three second walls. Each of the first walls is connected between adjacent two of the second walls. The hole section is defined to have a central axis and a reference plane perpendicular to the central axis. On the reference plane, a side length of at least one of the first walls is smaller than side lengths of the second walls. With such design, the receiving hole could receive a head of an adapter and could rotate the adapter as a screwdriver.

Abstract: A conventional blind rivet tool with modified nose housing, i.e., a rivet gun with replaceable and interchangeable nosepieces, facilitates feeding and setting of multiple diameters of blind rivets with substantially shortened exposed mandrel portions extending beyond the head flange of the rivet, all while maintaining blind rivet performance and reducing total installed blind rivet costs. A rivet with a reduced exposed mandrel protrusion relative to conventional and standardized mandrels can be enabled and more easily fed through the tool.

Abstract: A blind-rivet gun includes a gun header, a cylinder, a piston, and a tube. The cylinder is separated from the gun header. The piston includes a piston header. The piston header and an inner surface of the cylinder form a seal to divide the cylinder into a first air chamber and a second air chamber. The cylinder includes a first gas hole and a second gas hole. The first gas hole is connected to the first air chamber, and the second gas hole is connected to the second air chamber. The piston is adapted to slide in the cylinder to generate inner high pressure gas by alternatively supplying outer high pressure gas to the first gas hole or the second gas hole. The tube is connected to the gun header and the cylinder. The tube transmits inner high pressure from the cylinder to the gun header.

Abstract: A tool for setting blind fasteners is disclosed. A stem of a fastener is engaged by a pulling head and its sleeve is also engaged by the pulling head. In an initial stage, a pump piston compresses fluid in a hydraulic pump, affecting movement of a drawbar and piston in relation to a stationary adaptor connected to the tool, pulling the stem in relation to the sleeve at a fast rate per pump. As the pulling force increases, pressure in the pump triggers a logic system to shift the tool into a high pressure mode, decreasing the effort to complete fastener installation. The logic system resets after each squeeze of the lever, minimizing the number of pumps necessary to complete the installation while keeping effort at a comfortable level. An adjustable pressure relief valve allows the fluid to return to the reservoir chamber, returning the tool to its initial condition.

Abstract: A trigger device is mounted on a rivet gun. The rivet gun has a barrel, a handle and a pneumatic cylinder. The trigger device has an inlet channel defined in the handle, an outlet hole defined through the handle and communicating with the barrel, a valve-driving channel defined in the handle and communicating with the pneumatic cylinder, a space defined in the handle and communicating with the inlet channel, outlet channel and valve-driving channel. A trigger member is mounted on the handle. A two-step pressing assembly is mounted in the space and may be activated to control the rivet gun to eject a core pin of a used rivet or rivet pieces with an unused rivet. High-pressure air from an air source connected to the rivet gun is output only during the ejection operation of the rivet gun to prevent unnecessary air consumption and noise.

Abstract: A rivet tool capable of measuring size of blind rivet has a body and multiple interchangeable nosepieces. The body further has multiple rivet body measuring holes formed through the body. Diameters of the rivet body measuring holes match rivet bodies of corresponding blind rivets. Accordingly, the rivet tool of the present invention employs the rivet body measuring holes to measure a size of a rivet body of a blind rivet to rapidly, conveniently and correctly obtain a size of a rivet body of a blind rivet and further to correctly choose a nosepiece with a matching size.

Abstract: A rivet gun for setting a self-tapping rivet in one or more work pieces has a tool body having a handle for gripping, a rotation assembly having a motor attached to an axially adjustable shaft and a chuck to thereby impart rotation to the chuck adapted to grip and rotate the shank of the self-tapping rivet. A hydraulic assembly having a pull bushing is connected to a piston rod attached to a piston and a retraction assembly having a mandrel clamp and a mandrel clamp ring is connected to a spring guide biased toward the mandrel clamp by a spring to thereby compress the mandrel clamp to grip and retract the shank, set the self-tapping rivet in the work pieces and detach the shank from the self-tapping rivet.

Abstract: A low swage load fastening system is provided for installing swage-type fasteners to secure a plurality of workpieces together. The fastener includes a pin member having an elongated pin shank to be located in aligned openings in the workpieces. An enlarged head at one end of the pin engages one side of the workpieces. A grooved pin portion extends past an opposite side of the workpieces. A collar includes a shank portion adapted to be swaged into the pin lock grooves in response to a relative axial swage load applied by an installation tool. As one aspect of the system, the collar is as-headed and does not require thermal processing yet provides an optimum balance of reduced collar shank wall thickness and increased hardness, whereby the swage load is minimized. A low swage load thread form for the lock grooves of the pin is also provided, a reduced diameter, relatively short pull portion pin extension, installation tool improvements, and an associated method of use are also disclosed.

Abstract: To set two-part fasteners (8), in particular blind rivets, in which for setting a first part (7) has to be pulled while a second part (6) is held, a device is proposed with a housing (1), a feed appliance (9) on the housing (1) to transfer a fastener (8) into the housing (1) through an orifice (12) in the housing (1), an abutment (3), which holds the second part (6) during the setting process, and a pulling device pulling the first part (7) during the setting process, which has a gripper (5) at an open end of a pulling element (4) which cooperates with a pulling piston (13) which is movable forwards and backwards along an axis of the housing (1) in a first chamber (14) by an actuating unit. To transfer a fastener (8) the pulling element (4) opens the orifice (12). The pulling element (4) extends through the piston (13). The pulling piston (13) and the pulling element (4) are movable relative to one another along the axis. The pulling element (4) has a piston (17) on the end opposed to the gripper (5).

Abstract: A rivet setting tool is provided including a pulling head and a jaw case connected to the pulling head such that the jaw case is driven by the pulling head to engage a rivet mandrel. Air is supplied to the pulling head to return the pulling head to its original position after a rivet has been set. A remote intensifier is provided including an air piston disposed in a piston chamber and a rod connected to the air piston and extending into a ram housing which is connected to a hydraulic passage which is connected to the pulling head. A first supply of pressurized gas communicates with a first end of the piston chamber and a second supply of pressurized gas communicates with a second end of the piston chamber for rapidly returning the air piston to the retracted position in combination with the air pressure applied to the pulling head. The second end of the piston chamber is vented to prevent to much pressure build up pushing the piston to the retracted position.
