Definitions

  • Blind rivets consist of a hollow rivet which has a flange-shaped rivet head at its end and is penetrated by a nail-shaped rivet pin, the upsetting head of which is supported against the other end of the hollow rivet.
  • the shaft of the hollow rivet is inserted through aligned holes in the parts to be joined, usually made of sheet metal, and the rivet pin is pulled out of the latter by means of a tool which is supported on the head of the hollow rivet, the compression head of the rivet pin the free end of the Widen the shaft of the hollow rivet to a second rivet head and in most cases also cause the shaft to be compressed.
  • the shaft of the rivet pin is usually provided with a predetermined breaking point, which yields when the riveting process ends, the compression head and a subsequent stub of the rivet pin remaining in the set rivet.
  • the upsetting head is pulled through or pulled out of the hollow rivet.
  • the rivet pin has to be pulled over a drawing distance in order to adequately deform the hollow rivet and therefore to accomplish the riveting process.
  • the present invention is now a blind riveting with a aufruhenden on the hollow rivet support and at the with an edging means of clamping jaws - engaging head provided rivet-drawn part, which is guided out of its supported on the support starting position through a drag distance retracted and a radially movable, with a rotatingly driven spindle which can be brought into and out of engagement with a threaded segment, the drawing part being motor-driven over the drawing section.
  • the threaded segment In a known blind riveting device of this type, the threaded segment must be operated by hand, namely pressed into its engagement position before the riveting process, held in this position during the riveting process and retrieved from this position after the riveting process has ended.
  • this is not only a manual, but also a mental burden, since full attention is required to avoid incorrect manipulation.
  • the object of the present invention is to provide a blind riveting device in which the riveting process is carried out completely without manual intervention by the operator.
  • This object is achieved by the characterizing features of claim 1. Thanks to the appropriate design, the device only needs to be pressed against the objects to be connected to one another in order to start the riveting process, the individual device parts automatically returning to their starting position as soon as the riveting process has ended and the rivet pin has either been torn off or has been pulled out of the hollow rivet.
  • the housing of the electric drive motor has a cylindrical extension 1, in which a cylindrical sleeve 2 of the support, which is denoted overall by 3, is guided so as to be longitudinally displaceable. Under the action of a spring 4, the sleeve 2 is supported at 5 with its deposition on a shoulder of the extension 1.
  • the support 3 has a support head 14 in the form of a hollow cone, which is firmly connected to the sleeve 2.
  • the front end of the support head 14 is formed by a guide piece 6 designed in the manner of a cap screw with an axially extending guide channel 7. The latter serves to receive the rivet pin 32, the shaft 33 of which is inserted into the channel 7 from the front and has a predetermined breaking point at 34.
  • the guide piece 6 is preferably made of magnetic material to give the blind rivet a temporary hold.
  • the cylindrical shaft 8 of an overall drawing piston 9 is guided.
  • This has a conical piston head 10, which rests in the drawn starting position of the drawing piston 9 according to Fig.l under the action of a spring 11 on the inner wall of the support head 14, wherein the drawing piston 9 is supported on the support 3.
  • a spring chamber 12 extends through the piston head 10 and ends in the direction of the channel 7 at 13 in an inner cone.
  • clamping jaws 15 are arranged, which together form an extension of the channel 7 and act on the shaft 33 of the rivet pin 32 under the action of a spring 16 and the cone 13 located in the spring chamber.
  • the clamping jaws 15 are supported on the guide piece 6, being somewhat pushed back against the action of the spring 16, so that the shaft of the rivet pin is not held firmly by the jaws 15.
  • the contact surfaces of the clamping jaws 15 with the guide piece 6 can be concave / convex, so that the clamping jaws can be pushed apart not only axially, but also radially apart. Thanks to these precautions, the shaft of the rivet pin can be inserted without further ado, but also — as will be explained below — can be easily pulled out or ejected after the magnetic holding force has been overcome.
  • radial bores 17 play a role, which connect the spring chamber, which is sealed at its rear end by a screw 18, to the cavity 19 (see also FIG. 3), which lies in front of the drawing piston 9. if this is withdrawn from its starting position.
  • the drawing piston 9 has an axial bore 19 in which a slide 20 is guided, which is located at the end of a threaded spindle 21.
  • the thread 22 starts at a distance from the slider 20 and it extends up to an oblique shoulder 23.
  • a threaded nut segment 24 provided with a corresponding internal thread is located in a radially displaceable manner in an inner bore 25 of the shaft 8 of the drawing piston 9.
  • segment 24 comes into the region of this extension, it can be displaced radially outward to such an extent that it disengages from the thread of the spindle 21.
  • the longitudinal displaceability of the sleeve 2 is limited by mutually cooperating stops 29 and 30 of the support on the one hand and the extension 1 on the other.
  • a wedge arrangement indicated at 31 enables the sleeve 2 or the drawing piston 9 to be displaced, but ensures that these parts cannot start to rotate.
  • a further wedge arrangement 35 prevents the nut segment 24 from rotating about its own axis without preventing its radial displacement.
  • the shaft 33 of the rivet pin 32 is first inserted into the guide channel 7 of the guide piece 6 and then the hollow rivet 37 through holes which are aligned with one another Inserted sheet metal parts 38 and 39 until the rivet head 40 is pressed against the sheet metal part 39 by the guide part 6.
  • the sleeve 2 of the support 3 is pushed into the extension 1 as far as the stops 29 and 30 allow.
  • the thread segment 24 of the support 3 engages with the thread 22 of the motor-driven spindle 21, so that the drawing piston 9 is pulled away from the support in its stop position.
  • the jaws 15 stand out from the guide piece 6 so that they grip the shaft 33 of the rivet pin 32 firmly under the action of the inner cone 13.
  • the drawing piston 9 is forced to move further by the spindle 21, the rivet pin is therefore also pulled.
  • the threaded segment 24 is supported radially outwards on the inner wall of the sleeve 2, which accordingly forms a lock for the threaded segment 24 in the region of the drawing section.
  • the spindle 21 is equipped with a saw thread, the thread flanks essentially perpendicular to the axis facing the drive motor, so that no or no substantial radial force component acts on the segment 24.
  • the spring 11 can push the drawing piston 9 back into the support 3 until the piston head 10 rests on the support head 14.
  • the tool will hardly continue to be pressed against the sheet metal parts 38/39, especially since the spring 4 tries to push the sleeve 2 of the support out of the extension 1.
  • the support thus reaches its starting position shown in FIG. 1 before the drawing piston 9 is uncoupled from the spindle 21 under the action of the inclined surface 23. This leads to a further increase in the cavity 19 which arises in front of the piston head 10 of the drawing piston when it is withdrawn.
  • the blind rivet is set in the manner described above and the rest of the rivet pin or the rivet pin is ejected after the riveting process.
  • the extension 28 ends in an inclined shoulder 43, the threaded segment 24 having a corresponding bevel 25. This will cause the thread segment to pass through the ball 26 pushed back certain locking position when the drawing piston 9 is returned to its starting position by the spring 11.
