Definitions

  • the invention relates to a method for setting Blind rivet nuts, in which the mandrel up to the stop is screwed into the nut thread in the nut thread and then axially displaced so that the thin-walled material of the cut part dodges outwards and one Bead forms.
  • the invention is therefore based on the object To make available procedures in which lower forces during Setting blind rivet nuts are necessary and therefore the Handling of mechanical devices simplified and the Requirements for hydro-pneumatic devices are reduced.
  • the invention is that one previously stored force during the riveting process Traction supports.
  • the invention also makes a device Implementation of the procedure available, which consists in that a device is provided before the riveting process stores a force and this during the riveting process Provides support for the traction applied.
  • the invention proposes before that the storage device consists of a spring, which can be specially designed as a compression spring.
  • the invention is based on two Embodiments are explained in more detail.
  • Fig. 1 shows a mechanical device consisting of a transverse bearing 1 in which a guide tube 2 is fixed is screwed, which serves to mount the housing 3, so that this is axially displaceable against the transverse bearing 1.
  • a mandrel 4 which by the Guide tube 2 protrudes from the housing 3 and there is connected to the mandrel 10.
  • the mouthpiece 11 is screwed in and over a Knurled nut 12 countered.
  • the cross bearing 1 is with the Housing 3 connected by the lever arms 8 in the transverse bearing 1 be stored with a cross pin 7 and the tabs 6 in Housing 3 with a cross pin 5 and in the lever arm 8 with a cross pin 9 are stored.
  • Fig. 2 is a hydropneumatic Tool represented that in the same way supports the traction to be applied.
  • the Pneumatic cylinder 21 generated by a hydraulic Piston 22 a drive in a hydraulic cylinder 23, the axially moves the mandrel 24 against the mouthpiece 25.
  • a previously compressed spring 26 supports the Movement of the hydraulic piston 22 so that the Driving force by the spring 26 is reduced.
  • the Storage device shown as a spring, which as Coil spring is formed.
  • Force storage devices to support the tractive force such as. B. a motion-dependent switching on of a print medium, which when Pulling back the mandrel is relieved.
  • B. a motion-dependent switching on of a print medium, which when Pulling back the mandrel is relieved.
  • the storage device serves to support the traction through the Storage device of the first phase of the riveting process, at which the greatest force is required to avoid the Wall material of the cut part of the Initiate blind rivet nut. Is this process completed is the additional application of a force no longer required by the storage device, but even harmful at the end of the riveting process therefore to refrain from doing so.
  • the storage device therefore has to find out an appropriate interpretation.
