  • Patent number: 10695823
    Abstract: A drive unit is configured for a stamping rivet setting device and has an electric direct drive which contains motor components that concentrically surround a control element which can be linearly moved in the axial direction. In order to absorb the required torques while allowing a compact construction of the device, in particular in relation to a component side, a drive housing has an asymmetrical configuration in a connecting region between a main part and a guide part in which the control element is guided, for the purpose of asymmetrical torque transmission. In addition or alternatively thereto, the highly compact construction achieves an efficient cooling by an inner cooling unit, in particular air flowing through a free inner space in which the motor components are arranged.

  • Publication number: 20150074964
    Abstract: A blind rivet fastening device in which a passage for collecting broken mandrels is provided other than on the axis of the motor. A large collection chamber is provided for broken mandrels. A collection chamber for broken mandrels is provided in front of a brushless electric motor in the axial direction. When the electric motor rotates, power from the electric motor is transmitted to a spindle positioned to the rear of the collection chamber via a second shaft positioned below the collection chamber. When the spindle rotates, a pulling head moves in the axial direction. The axial position of the pulling head is determined by detecting the rotation count of the electric motor. Forward rotation, reverse rotation, and stopping of the electric motor are controlled based on the operation of a trigger and the axial position of the pulling head. Excessive torque is avoided by clutches.

In use, a collapsible insert is threaded onto the tool and the insert is positioned in a hole in a workpiece. An actuating handle of the tool is then rotated, while holding the stabilizing handle, to cause the collapsible insert to collapse, thereby installing the insert relative to the workpiece. Once the insert has been collapsed using the tool, the actuating handle is rotated in the opposite direction, while holding the stabilizing handle, to disengage the tool from the insert. Then, a hanger is threadably inserted into the collapsed insert and a threaded rod is threaded into the hanger. Alternatively, the threaded rod is directly threadably engaged with the collapsed insert, without need for a hanger.

In order to reduce the power consumption of a riveting apparatus of that kind, the invention provides at least one flywheel which can be connected in a releasable manner with the motor shaft via a coupling.

  • Patent number: 6212931
    Abstract: A rivet setting tool for setting blind rivet nuts has a rotation reversal device including a valve slide and a slide housing that is moveable into a forward position and a rear position, a rotary motor connected to a feed spindle and having a direction of rotation that is controllable by the rotation reversal device, a pressure medium piston/cylinder device that is operable for a rivet upsetting process and confers an axial motion on a threaded bolt via the feed spindle, and a device that actuates the pressure medium piston/cylinder device and the rotation reversal device. The rotation reversal device includes a fixing device that at least temporarily fixes the position between the valve slide and the slide housing, the fixing device engaging with the valve slide.

  • Patent number: RE46857
    Abstract: The present invention provides a small electric blind rivet setting device that is capable of being driven by a battery and that does not require a pathway for recovering the broken mandrels to be provided in the motor shaft. A recovery container 10 is provided in a tool housing 27 forward of an electric motor 13 in the axial direction, and a spindle 14, which rotates because of the rotation of a drive shaft 18 connected to the electric motor circumventing the recovery container, is connected so as to move a pulling head (30) in the axial direction. The positive rotation, stopping of rotation and reverse rotation of the electric motor are controlled by a pulling operation on a trigger and detecting the position of the pulling head in the axial direction.
