Abstract
The present invention relates to a rivet setting device having an electric drive motor, a rivet setting means in a crank drive for driving the rivet setting means by the drive motor, wherein the crank drive assumes a rest position in one of its dead-center positions and, starting from its rest position, can be rotated by at least one complete rotation for performing a rivet setting operation of the rivet setting means. In order to simplify the construction of such a rivet setting device, the drive motor, the crank drive and the rivet setting means are in permanent operative communication according to the invention and a control means is provided for deactivating the drive motor when the crank drive is in its rest position after the rivet setting operation has been carried out.
Claims23
A rivet setting device comprising:
- an electric drive motor,
- a rivet setting means,
- a crank drive for driving said rivet setting means via said drive motor, wherein said crank drive assumes a rest position and, starting from the rest position, can be rotated by at least one complete rotation for performing a rivet setting operation of said rivet setting means, characterized in that said drive motor, said crank drive and said rivet setting means are in permanent operative communication, and
- a control means for automatically deactivating said drive motor when said crank drive is in the rest position after the rivet setting operation has been performed.
A rivet setting device comprising:
- an electric drive motor,
- a rivet setting means,
- a crank drive for driving said rivet setting means via said drive motor, wherein said crank drive assumes a rest position and, starting from the rest position, can be rotated by at least one complete rotation for performing a rivet setting operation of said rivet setting means, characterized in that said drive motor, said crank drive and said rivet setting means are in permanent operative communication, and further wherein the rest position is either a front dead-center position facing said rivet setting means or a rear dead-center position,
- a control means for deactivating said drive motor when said crank drive is in the rest position after the rivet setting operation has been performed,
- a flywheel operatively connected to said drive motor, wherein said flywheel can be coupled with and decoupled from said drive motor, and further wherein the rest position is the front dead-center position when the setting stroke of said rivet setting means starts,
- a sensing means for sensing an angular position of said crank drive so as to determine whether said crank drive is in its rest position, wherein said sensing means comprises a mechanical switch which cooperates with the control means of said crank drive, and
- at least one rechargeable battery.
A rivet setting device comprising:
- an electric drive motor,
- a rivet setting means,
- a crank drive for driving said rivet setting means via said drive motor, wherein said crank drive assumes a rest position and, starting from the rest position, can be rotated by at least one complete rotation for performing a rivet setting operation of said rivet setting means, characterized in that said drive motor, said crank drive and said rivet setting means are in permanent operative communication, and further wherein the rest position is either a front dead-center position facing said rivet setting means or a rear dead-center position,
- a control means for deactivating said drive motor when said crank drive is in the rest position after the rivet setting operation has been performed, and
- a flywheel operatively connected to said drive motor, wherein said flywheel can be coupled with and decoupled from said drive motor.
