Definitions

the invention relates to a blind rivet nut setting device according to the preamble of claim 1.
blind rivet nuts With blind rivet nut setting tools, so-called Blind rivet nuts attached to suitable walls.
the Blind rivet nuts consist of a flange-like head, a thin walled shaft and a nut and can be inserted into the Drilling a wall.
the blind riveting tool engages in the thread of the nut and pulls the nut against the head, the thin-walled shaft bulging and forms a flange-like abutment, between which the Edge of the wall is clamped to the blind rivet nut is to be attached.
the mandrel engaging in the blind rivet nut of the setting tool is high loads and wear exposed. By constantly screwing and unscrewing the Threaded mandrel will wear its thread. It can Lifetime of the mandrel through appropriate choice suitable material and hardening of the surface are, however, such mandrels are then quite expensive. For smaller diameters of 6 mm and below this, there is also frequent breakage of the mandrel.
the invention has for its object a solution to specify, which does not require expensive mandrels.
the task is solved in that the Threaded mandrel each by an interchangeable, standardized Bolt is formed with head, which Has coupling designs with corresponding Work together the coupling formations at the end of the mandrel.
connection of the standardized screw bolts with the rotatable Pulling pin provided a union nut, the one Through hole with a diameter that all Pick up the bolt sizes intended for the device can, and they are washers or perforated Washers for adjusting smaller ones Bolt sizes are provided on the through hole.
all blind rivet nut sizes that are suitable for the setting tool are provided after a minor modification deal with.
Fig. 1 shows a blind rivet nut setting device with broken operating lever arms and mandrel or Bolts.
the blind rivet nut setting tool shows as Main parts a housing 1, a mandrel 2, a Rotary device 3 for the mandrel, a longitudinal drive 4 for the mandrel and a mandrel 5.
the housing 1 has a cavity 10 which ends in a mouthpiece 11, in which the mandrel 5 is guided.
the mandrel 5 is connected to the mandrel 2 by means of a union nut 12.
a knob 3 is attached, which represents the turning device of the mandrel.
Longitudinal drive 4 of the mandrel is only sketchy here shown and contains, for example, two operating levers 14, which are connected to the housing 1 via an axis 15 and over further axes 16 and a transverse bearing 17 with the Pull mandrel 2 are connected to this in the axial direction to drive.
blind rivet nut 30 shows schematically the approximation of the to the front end of the blind rivet nut setting tool Blind rivet nut 30.
This contains a flange-like head 31, a hollow shaft 32 and a nut 33. How it can be seen that the hollow shaft 32 is opposite the nut 33 cut free, d. H. thinner than the mother 33, whose Thread is designated with 34.
the blind rivet nut 30 is in the bore of a wall 35, for example one Sheet metal.
the mandrel 5 By turning the knob 3, the mandrel 5 can in the Thread 34 are screwed, and by pressing the Longitudinal drive 4, the mandrel 5 together with the Nut 33 are pulled up as shown in Fig. 4th is shown.
the shaft 32 bulges outwards and forms a bead 36 which forms a flange 37 (FIG. 7) is deformed further.
the edge of the Wall 35 of the head 31 and the flange 37 of the Blind rivet nut clamped and thus the blind rivet nut attached to the wall 35.
Fig. 6 shows the mandrel 2. At the lower end of the Buchdorns 2 coupling training 20 are provided for Transfer of torque to the mandrel 5 is formed are.
the mandrel also has a screw thread 22 to match to the union nut 12. Another thread 23 is used for Attachment of the button 3.
Standard screw bolts serve as the mandrel 5 have a coupling formation 21 on their head 25.
the Thickness of the mandrel 5 must be the inside diameter of the nut 33 be adapted, which is why there are graduated sizes of Bolt 5 there. But it should only be one Union nut 12 can be used, the Through bore is designated 24. If the Contact surface of the head 25 around the bore 24 would be small, a perforated washer or a ring 26 between the head and ring shoulder of the union nut 12 added, which increases the contact area accordingly.
the coupling training 20 and 21 must therefore match each other than the screwing torque to Screwing the mandrel 5 into the internal thread 34 of the Mother 33 can be transferred.
8 shows an example Allen training on the head 25 of the bolt 5, formed through a hexagonal hollow cylinder.
Fig. 6 shows a coupling formation 20, which a number of Allen training 21 can operate.
the coupling training 20 in Fig. 6 consists of a hexagonal pyramid or Truncated pyramid. The pyramid faces the Edge of the hex training 21 and transfer the necessary Force to screw the mandrel 5 into the thread 34 mother 33
a step pyramid can also be used, i. H. a Pyramid made up of hexagonal sections.
a Such training can also involve larger forces transfer.
Fig. 9 shows a further embodiment of the Coupling formation at the lower end of the mandrel 2, namely this consists of intersecting ribs 27, as in FIG. 10 shown.
the head 25 has one Phillips 28 on, as indicated in Fig. 12.
the slots 28 can also be arranged in a star shape in order to ribs 29 arranged in a star shape (FIG. 11) to work together.
Coupling training can be used.
so-called posidrive or torque transmission devices suitable.
