    摘要: A pressing tool having an electric motor fed by a battery. The electric motor drives a gear pump with two rotor shafts which are accommodated in a hydraulic block. The rotor shafts are mounted in a gear housing on one side of the hydraulic block and in a cylinder housing of a piston cylinder unit which bears on an other side of the hydraulic block. This gear pump uses an extremely simple construction manner and simultaneously achieves a high delivery volume. The high delivery volume leads to an extremely low loading of the battery, by which its operational duration is increased.

    摘要: A manually applied installation tool, for setting fasteners by applying a relative axial pulling force thereto and including a first hydraulic piston in a first hydraulic cylinder for reciprocation in response to a preselected high hydraulic pressure for applying the relative axial pulling force, a second hydraulic piston in a second hydraulic cylinder for reciprocation between compressive and non-compressive directions for providing hydraulic fluid at the high hydraulic pressure to the first hydraulic cylinder for application of the axial pulling force by the first hydraulic piston, a fluid reservoir having a supply of hydraulic fluid for compression by the second hydraulic piston and flow to the first hydraulic cylinder through an access valve, a high pressure relief valve connected to the second hydraulic cylinder and actuable to relieve the fluid pressure at a preselected high magnitude with flow of hydraulic fluid back to the fluid reservoir. The installation tool including a refill valve operable for permitting flow of hydraulic fluid from the fluid reservoir into the second hydraulic cylinder upon reciprocating movement of the second hydraulic piston in a non-compressive direction and with the pressure relief valve, refill valve and access valve being substantially axially in line with the second hydraulic piston along its axis of reciprocation.

    摘要: An offset nose assembly for installing fasteners is provided that generally includes a drawbar, a swage anvil and a collet. The drawbar has three portions with the third portion transitioning from the second portion by a chamfer, the chamfer being of a preselected angle that is adapted to positively engage a chamfer of a preselected angle of a piston of a fastener installation tool. Additionally, a generally L-shaped guard assembly is provided that is disposed on the collet to cover a gap defined between the collet and the swage anvil. Also, a deflector is provided that is attached to a nut that is threadedly engaged with the rearward end of a bore in the collet, the deflector having a section of a uniform constant outside diameter that integrally transitions to a section that has an outside diameter that gradually lessens along its length.

    摘要: A pneumatic-hydraulic blind riveting device has a device housing and a pulling device arranged in the device housing. The pulling device has a chuck housing and chuck jaws arranged in the chuck housing. The pulling device has a pulling piston connected to the chuck housing and also has a return piston. The pulling device has a pressure bushing arrangement resting against the chuck jaws and interacting with the return piston. A pressure chamber is defined between the return piston and the pulling piston. A control device is designed to load the pressure chamber with a controlled pressure.
