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 traction applied is such a procedure not constant during the entire riveting process, rather, for example, two are towards each other moving hand levers towards the end of the movement force applied is greatest.
  • the greatest force is required at the time when the material of the cut out part begins to move outwards while with progressive movement an ever smaller Force is required until the end of the riveting process must be broken off when the bead hits the wall the borehole to damage the thread avoid.
  • the wall thickness in the cut part of the Blind rivet nut is preferably chosen so that the Clamping force of the bead being formed is as large as possible later act as an anti-twist device.
  • the invention is therefore based on the object To make available a process in which the setting of Blind rivet nuts easier, safer and more economical is made possible.
  • the mentioned type suggested that one from the beginning of the axial Movement of the blind rivet nut applied decreasing tensile force becomes.
  • the invention also makes a device Implementation of the procedure available.
  • a device for setting blind rivet nuts to carry out the A method according to claim 1 or 2, which has a tensile force Formation of a bead through the thin-walled, applies the cut-out part to the blind rivet nut, is characterized in that a decrease in traction mechanical translation is provided.
  • a decrease in traction Pressure reducer is provided.
  • 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 shows a further solution, the is that the cross bearing 1 with the housing 3rd is connected by the lever arms 8 in the housing 3 with a Cross pin 2, 7, 27 are stored and the tabs 6 in Cross bearing 1 with a cross pin 2, 5, 25 and in lever arm 8 be stored with a cross pin 2, 9, 29.
  • the housing 3 with the mouthpiece 11 against the Threaded mandrel 10 with a likewise decreasing Power transmission When pressed lever arm from position 1 to position 2 the housing 3 with the mouthpiece 11 against the Threaded mandrel 10 with a likewise decreasing Power transmission.
  • Fig. 3 shows a modification in which a mechanical device consists of a transverse bearing 31 in which a guide tube 32 is screwed, which for Storage of the housing 33 is used so that this against the Cross bearing 31 is axially displaceable.
  • a mechanical device consists of a transverse bearing 31 in which a guide tube 32 is screwed, which for Storage of the housing 33 is used so that this against the Cross bearing 31 is axially displaceable.
  • cross bearing 31 and housing 33 move away from one another, what with one in between and both connected spring 34 to a constant increase in Resistance leads.
  • Fig. 4 Another solution, particularly suitable for hydro-pneumatically driven tools, is in Fig. 4 shown and is the stroke against a increasing power to drive.
  • Any type of spring is suitable or suspension or a construction based on the system of the shock absorber.
  • the pulling force of the device can change during the stroke can be reduced by doubling the pneumatic cylinder acting cylinder is designed and initially on the return stroke after riveting against a compression spring 57 runs and part of the necessary for the next step Force thus saves. This not only does the desired thing degressive traction, but also allows an essential one Improve the performance of the cylinder, which is either has more power or can be designed accordingly smaller can.
  • the tensile force can also be applied to mechanical tools can be reduced during the stroke by the spring 4 is designed as a compression spring and when opening the tool part of the necessary for the next step Strength stores. This not only does the desired thing degressive traction, but also allows an essential one Improve the performance of the tool, which is more Force generated or designed accordingly smaller can.
  • the spring can be designed so that when Supporting the beginning of the riveting process and in the final phase has an inhibitory effect. This is accomplished by one and the same Spring used both as a compression spring and as a tension spring becomes. When the tool returns, it passes over hers relaxed state into a state storing the strength and thus acts as a compression spring. Supported during the riveting process the spring pulls the tension of the Degressive tool, as already described, then as Tension spring to reduce this force even more.
  • Oil brakes, shock absorbers, frictional resistances of all kinds all are nevertheless suitable for achieving the same technical effect.
