  • the jaws are not guided in their the rivet mandrel releasing state in the circumferential direction and form between them a free space.
  • the inventor of the present invention has found that such enlargements of slots between clamping jaws can occur and that the rivet mandrel can buckle into such a slot during the setting process. This leads to a complete blockage of the device.
  • the object of the invention is to provide a rivet setting device which operates reliably even after long use and under difficult conditions.
  • the invention proposes a Nietsetzêt with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
  • the rivet setting device proposed by the invention thus has a holder for the rivet mandrel, which is designed or guides the rivet mandrel such that a lateral deflection of the rivet mandrel is prevented.
  • the holder is designed so that it is substantially closed in the circumferential direction, in particular at the end facing the plunger, that is, any free spaces are arranged so that the rivet mandrel can not penetrate, for example because they are close to the rivet, or because they are smaller than the mandrel diameter in the circumferential direction.
  • the holder for the rivet mandrel has at least two radial slots, in each of which a clamping jaw is guided radially displaceably with little play.
  • the slots for the clamping jaws have a width that is smaller than the diameter of a rivet mandrel of a rivet to be set, for example has a width of 1 - 1, 5 mm with a rivet mandrel diameter of 2.8 mm.
  • the clamping plates are arranged in sliding fit in the slots and therefore have a corresponding width.
  • the rivet setting device has a push device for setting the rivet, which includes a plunger which acts on the free end of the arranged in the cylindrical passage Nietdorns.

  • the diameter of the passage in the holder for the rivet mandrel is preferably slightly larger than the diameter of the rivet mandrel, so that the rivet mandrel is guided reliably.
  • the passage can thus also form a guide for the plunger.
  • the plunger has a diameter approximately equal to the diameter of the mandrel.
  • clamping jaws are guided in the slots with little play and axially limited movable. This axial displacement of clamping jaws can be exploited to push them out of engagement with the rivet mandrel by means of compressive forces in the axial direction.
  • the slots can be evenly distributed in the circumferential direction, wherein preferably three slots are provided.
  • the traction device that is required for setting the rivet in a further development of the invention in the region of its front of the holder for the rivet to be set end associated with a clamping sleeve have in the pulling direction expanding inner cone with which it rests against the outside of the clamping jaws.
  • a pressure spring can be provided which preferably acts on the holder of the blind rivet associated with the end of the pulling device in the axial direction in the direction of the jaw by means of a jaw closing device ,
  • the jaw closure may be a sleeve.
  • the jaw closure may preferably be guided axially displaceably on the holder for the blind rivet.
  • the holder of the rivet facing the leading edges of the slots in the holder are inclined, such that during the axial displacement of the clamping jaws these are also moved radially.

  • the Nietsetzêt shown in section in Figure 1 includes a housing 1, which is composed of several parts. At the front end, left in FIG. 1, there is an opening through which the rivet mandrel 2 of a blind rivet 3 passes. The rivet mandrel 2 extends far into the passage 4 of the holder 5 for the blind rivet. 3
  • the holder 5 for the blind rivet is arranged in the housing immediately behind the opening for the mandrel 2. It extends far into the housing.
  • the already mentioned passage 4 therefore also accommodates the plunger 6 of the setting device.
  • the holder 5 for the mandrel 2 has a plurality of radial slots 7, of which the section of Figure 1 shows such a slot 7.
  • the front in the direction of the blind rivet 3 front wall 8 of the radial slot 7 extends from inside to outside obliquely, as well as the rear end wall 9.
  • the two end walls 8, 9 diverge outwards.
  • a clamping jaw 10 is displaceably guided in the radial direction and in the axial direction.
  • the clamping jaw 10 has an inner side 1 1 provided with rounded teeth, which runs approximately parallel to the axis of the rivet mandrel 2.
  • the inside 1 1 is an outer side 12 which runs obliquely, the dimension measured in the radial direction of the clamping jaw 10 increases from the front of the device, on the left in FIG. 1, towards the rear.
  • the front edge 13 of the clamping jaw 10 extends complementary to the front edge 8 of the slot. 7
  • Both the holder 5 for the rivet and the clamping jaws 10 are surrounded by a clamping sleeve 14, which has on its inner side 15 a right-opening funnel shape. With this inner side 15, the clamping sleeve 14 abuts against the outer side 12 of the clamping jaw 10.
  • a jaw closure 16 On the holder 5 for the mandrel a jaw closure 16 is mounted, which is acted upon by a compression spring 17 in the direction of the clamping jaws 10.

  • the clamping jaws 10 are applied to the outside as far as the clamping sleeve 14 permits. If the clamping sleeve 14 is pulled to the right, then the clamping jaw 10 shifts radially inwards and thereby jams on the rivet mandrel 2.
  • FIG. 2 shows the holder 5 for the rivet mandrel with an inserted mandrel 2.
  • the outer sides 12 of the clamping jaws protrude from the radial outer side of the holder 10 out.
  • At the rear end of the jaws 10 of the jaw closure 16 is with its end face 17 at. It can be seen here that the clamping jaws 10 are secured by the slots in the holder for the rivet mandrel so that they can move only in the radial direction and slightly in the axial direction, but not in the circumferential direction.

  • the thickness of the clamping jaws 10 corresponds to the width of the slots 7.
  • the clamping jaws are fixed in the circumferential direction.
  • the width of the slots is smaller than the diameter of the rivet mandrel 2.
  • the holder 5 shows the holder 5 with the clamping jaws 10 guided in it and a blind rivet 3 guided in it.
  • the holder 5 can be divided into a front section which guides the clamping jaws 10 and into a rear section which adjoins and is separated by a transition shoulder , cylindrical area, can be divided.
  • the rear section serves to guide the rivet mandrel and has a length adapted to the mandrel 2 in order to ensure the guidance of the same.
  • the wall thickness of the rear portion may be reduced to a thickness sufficient for the guiding function of the mandrel 2 is.

  • the holder 5 is presently formed of a solid material, but may have 7 spaces in addition to the slots.
  • these free spaces should be designed so that they do not jeopardize the guidance of the Nietdorn 2. This can be realized, for example, in that the free spaces in the circumferential direction are smaller than the rivet mandrel diameter, whereby the penetration of the rivet mandrel 2 into such a free space is prevented. However, this can also be realized in that the free spaces at the front, for example between the clamping jaws 10, are formed so that the guidance of the rivet mandrel 2 is not affected by the free spaces.
