Definitions

  • the invention first relates to a riveting tool with a Hold-down and a riveting punch, the hold-down and the riveting punch hydraulically by means of a hold-down piston and a punch piston drivable are.
  • the hold-down piston within designed as a circular piston piston piston is arranged and the hold-down piston by means of radial Passing through the plunger with the hold-down is coupled.
  • the hold-down piston and the plunger concentric arranged to each other, wherein by the selected Arrangement the effective piston surface of the hold-down piston about the annular piston inner diameter accordingly smaller than the effective piston area of the plunger.
  • the riveting area, d. H. of the from the riveting temple to enforcing area is central arranged, with the hold-down concentric surrounds this area.
  • the hold-down piston and the plunger piston respectively by means of a spring in its initial position are biased, the spring of the plunger is set higher than the spring of the hold-down piston.
  • a return displacement of Downholder and riveting punch in reverse order occurs, for example, at an arrangement on an electric motor operated, hydraulic device of the type mentioned once a return valve in the device due to the passing of a predetermined maximum pressure opens and hereafter the restoring forces of the springs of hold-down piston and piston pistons are larger than the corresponding ones Piston surfaces acted upon hydraulic pressure.
  • the springs are arranged concentrically with each other.
  • the plunger has a central Cylinder forms, in which the hold-down piston is arranged, wherein further the return spring of Hold-down piston against one in the entrance area the cylinder arranged, leaving a passage Supported thrust washer.
  • the hold-down piston is located stop-limited in the spring-assisted starting position in the plunger, what the entrainment the plunger in the course of advancement of the Hold-down piston in the direction of the clamping position supports the element to be connected.
  • the hold-down and the riveting punch over a portion of its length as concentric mutually arranged and axially displaceable against each other Sleeve body are formed. As mentioned, becomes the entrance area of the cylinder with one, one Be provided passage leaving thrust washer.
  • a suitably designed Valve through which the previously shut off hydraulic volume relative displacement of the cylinder having Piston piston against the hold-down piston lets emerge. It is preferred that in the Position in which the riveting completely closed is the hydraulic volume in the cylinder is almost completely drained through the valve. at a subsequent relocation of the system due to the sinking hydraulic pressure in front of the piston is supported by spring-loaded relative displacement of the Plunger against the lowbutter piston over a second valve the previously drained hydraulic volume back into the cylinder before the hold-down piston sucked.
  • This embodiment enables by means of the valves one until the riveting even hold-down force is set.
  • the Rivets to be pressed can be used individually as well be fed out of a magazine or Nietgurt out.
  • the riveting tool for example, on a robot can be used in terms of rivet feed also on known hose blower feeders be resorted to.
  • a riveting tool 1 consisting essentially of an electric motor driven, hydraulic working device 2 and one, essentially a hold-down 3 and a riveting punch 4 having mounting head 5th
  • the hydraulic cylinder enclosing Neck 8, on which the holder head 5 can be arranged is.
  • the arrangement of the holder head 5 is preferably chosen so that a rotation of the same is ensured on the neck 8.
  • the recording 9 opposite C-leg of the Holder head 5 carries one, preferably interchangeable, a matrix forming Nietamboss 10 whose body axis extends in extension of the axis of the receptacle 9.
  • the hold-down 3 and the riveting 4 are by the same, by means of the driven in the implement Hydraulic cylinder applied pressure applied, why the hold-down 3 a hold-down piston 12 and the riveting punch 4 has a plunger 13.
  • the plunger 13 here has one, the inner diameter of the neck matched outer diameter, with a Piston ring seal 14 the sealing completion of before the plunger 13 formed by the hydraulic cylinder of the implement 2 to be acted upon pressure chamber 15 ensured in the neck 8.
  • the Nietstempel 4 and the plunger 13 are by means one the first section 17 and the second section 18 comprehensive compression spring 19 in the starting position biased according to FIGS. 4 and 5, which spring 19th at one end of the back of the plunger 13 and otherwise on the bottom side of an inner annular step 20th near the opening 11 of the receptacle 9 is supported.
  • the plunger 13 and its sections 17 and 18th are formed as a sleeve body 21, whereby a central, provided with an annular step 22 cylinder 23 is formed.
  • this cylinder 23 is the hold-down piston 12 slidably mounted in the axial direction, this with concentric arrangement of hold-down piston 12 and plunger 13.
  • the with a piston ring seal 24 provided hold-down piston 12 is located in one, the area of the plunger 13 and the area passing through the first portion of the plunger 13, cross section larger section 25 a and is supported in the starting position according to FIG. 4 and 5 at between this cylinder portion 25 and the subsequent cross-section reduced section 26 formed annular step 22 from.
  • In these cross-section reduced Cylinder section 26 in the region of the second Stamp piston portion 18 protrudes the piston skirt 27 of the hold-down piston 12, wherein its length about half the axial length of the cylinder portion 26th equivalent.
  • the hold-down 3 is as a, the second section 18 of the plunger 13 comprehensive sleeve body 33rd formed, with an outer diameter, which is the diameter the aperture 11 of the receptacle 9 adapted is.
  • the central is the hold-down 3 penetrating and thus internal riveting punch 4 with an outer punch piston 13 and the external hold-down 3 with an inside Retainer stamp 12 coupled. It follows that that the effective piston surface 16 of the plunger piston 13th is formed larger than the effective piston surface 36th the hold-down piston 12.
  • the device 37 is by means of a screw 43, which the receptacle 40 passes through the hold-down 3 or fixed to the sleeve body 33.
  • the hold-down head 41 is with a central Niet sacrificed labour.
  • the feed pawl 46 is at one in the device 37 sliding displaceable feed slide 48 rotatable attached, which feed carriage 48 by means of a Compression spring 49 in its initial position shown in FIG. 4th and 5 is biased.
  • the direction of movement of the feed carriage 48 and the feed pawl 46 against the spring force is marked with the arrow t.
  • the feed carriage 48 has a Handle 54 for hand release of the same on.
  • Riveting device 1 of the first embodiment is like follows:
  • FIGS. 9 and 10 show an intermediate position, in FIG which of the rivet 38 immediately before the to be connected Elements 55 and the feed carriage 48 by means the release element 51 against the force of the spring 49th partially relocated. This under towing the feed pawl 46.
  • Nietstempels 4 causes the piercing of the elements 55 by means of the processed Rivet 38, which in this case by the rear, a template forming Nietamboss 10 to form the Rivet connection is bent. At the same time is one further return displacement of the feed carriage 48 and thus the feed pawl 46 takes place, to a position, in which the feed tip 47 of the feed angle 46 behind a rivet 38 to be processed next lies.
  • FIGs. 23 to 26 another Embodiment shown in which without use a rivet only by deformation by means of Nietstempels 4, a disposal of the elements 55 is performed becomes.
  • This also forms the free end of the blank holder. 3 the hold-down head 41, wherein in the starting position as shown in FIGS. 23 and 24, the smooth-surfaced end face of the riveting punch 4 with the end face of the hold-down head 41 is aligned.
  • the Nietamboss 10 has two opposing to each other movable joining wings 62, which, leaving one corresponding to the diameter of the riveting punch 4 Distance a partially overlap the Nietamboss 10.
  • the between the joining wings 62 left Nietambossö réelle is designated by the reference numeral 64.
  • the joining wings 62 are about axes 63 transversely to the direction of movement r Nietstempels 4 at the Nietamboss 10th movably mounted, wherein the axes 63 in the illustrated Embodiment by one, the joining wings 62 acting in the starting position shown in FIG Spring ring are formed.
