Definitions

  • the invention relates to a setting tool for blind rivet nuts with a tubular housing, with a handle, with one at one end of the Interchangeable mouthpiece to hold a housing interchangeable pull screw, with an axially inside the housing movable holder, one end of which for the rotationally fixed reception of a interchangeable driving mandrel and its other from the housing projecting end for the rotatable and detachable mounting of a handle and is designed to attach a key, the free end of the respective driving mandrel for non-rotatable connection to the head of the replaceable pull screw is formed.
  • Such a tool is known from GB, A, 1 554 623 and is used for Setting blind rivet nuts in thin-walled materials, e.g. B. sheets, used, the strength of which is not sufficient to tighten a thread can.
  • the object of the invention is a blind riveting tool according to the preamble of claim 1 to improve that a safe, almost wear-resistant holder of easily and quickly replaceable Pull nuts is guaranteed even when high forces are applied have to.
  • This task is carried out by a setting tool with the characteristics of Claim 1 solved.
  • the setting tool 1 shown in Fig. 1 for setting blind rivet nuts in a thin-walled material has a tubular housing 2, the at one - the front - end 3 is tapered on the outside, and on the inside a gradual reduction in diameter compared to the Has main part of the housing 2.
  • the end 3 is a cylindrical Cavity with a smaller diameter and a cylindrical body Larger diameter cavity present.
  • a radial Handle 4 attached on the housing 2 a radial Handle 4 attached.
  • the End sleeve 26 (Fig. 3c, in plan view Fig. 3d) has a continuous central Inner bore 28 and a collar 27 with an end face 8 (Fig. 3a) for a blind rivet nut.
  • the collar 27 is used for support the end face of the front end 3 of the housing.
  • the end sleeve 26 ends in fully screwed in state before a step 10 (Fig. 1) between the cylindrical housing parts with different diameters.
  • the housing 2 From the open end of the housing part with the larger diameter is in the housing 2 uses an inner bearing in the form of a support ring 11, which is supported at level 10. It can be fixed in this position if necessary be, e.g. B. by a spring washer (not shown) or glued firmly.
  • the central opening in the support ring 11 and the inner bore 28 in the End sleeve 26 have a diameter that the passage of a Draw screw 12 allowed with little play. If the support ring 11 is not is attached interchangeably, its central bore has a diameter on the passage of the screw part of the pull screw 12 with the largest diameter allowed. The head 13 of each draw screw 12 should be support almost completely on the support ring 11, so that a large contact area consists.
  • a recess is made on the end face, into which a driving mandrel 14 can be rotatably inserted at one end.
  • the screw cap 16 is preferably designed so that its outer dimensions Correspond to the outer diameter of the housing 2, its surface non-slip, e.g. B. can be designed by corrugation.
  • the holder 17 (see Fig. 3h) has an annular Projection 18, which serves to support the screw cap 16.
  • the part of the holder 17, which extends through the screw cap 16 into the housing 2 extends, is preferably cylindrical.
  • Pressure coil spring 19 placed on the one hand on the screw cap 16, pressing it against the annular projection 18 and on the other hand a support, e.g. B. supports a snap ring 20 which in one in the area of the free end of the cylindrical holder part arranged groove 21 can be used is.
  • the outer part the holder 17 has a section for receiving a handwheel 23.
  • the handwheel 23 is removably mounted on the holder 17, the corresponding section of the holder 17 also cylindrical and one or can have several projections (not shown), which with corresponding recesses in the edge of the hand 23 - at least in the End position of the slide up to the annular stop 18 Handwheel 23 - can or can interact.
  • the outer part the holder 17 can also as a polygonal, for. B. hexagon mandrel (see Fig.
  • the handwheel 23 with a correspondingly designed central opening 24 (see FIG. 3i) can be pushed on in a rotationally fixed manner.
  • the outer part of the Holder 17 has a protruding over the pushed-on handwheel 23 Extension 25 on the approach to a tool such.
  • the Extension 25 in the form of a hexagon (see the opening 24 in Fig. 3i) executed.
  • the inner bore 28 of the end sleeve 26 is a receptacle Polygonal plug-in part 29 with head 30 (Fig. 3a; in Fig. 3b in cross section Line b - b shown in Fig. 3a) adapted.
  • the polygonal plug part 29 with the Head 30 has an axial central through opening 31, which for Passage of the drawing screw 12 with head 13 (Fig. 3f) serves and to her Dimensions is adapted and an end face 8 for one Blind rivet nut.
  • the bottom bracket can also consist of one or more bearing disks 32 and have a needle pressure bearing 33 (see FIG. 3e), which serves the Friction between the housing 2 and the head 13 of the pull screw 12 decrease if the pulling screw 12 for setting a blind rivet nut is rotated.
  • This bottom bracket can also be fixed or replaceable be arranged.
  • blind rivet nuts are set with different thread diameters to be pull screws 12 with the appropriate thread in the Setting tool 1 are used.
  • the bottom bracket is fixed and are not arranged interchangeably, they must pass through the Allow pulling screw 12 with the largest thread diameter.
  • To prevent thread diameters are given to the Interchangeable reducers (not shown) used.
  • the bearing disks 32 with the needle pressure bearing 33 arranged supported at level 10 and optionally fixed or at fixed bottom bracket is a customized reducer on the respective pull screw 12 pushed, after which the respective new one Pull screw 12 from the cover-side opening of the housing 2 through the Passages in the bottom bracket or mouthpiece are inserted until there is her head 13 or the reducer attached to it on the bottom bracket supports.
  • bottom brackets can also be used same passage diameter for several sizes of drawing screws 12 are used, which reduces the parts to be changed, a sufficient contact between step 10 and support ring 11, or Bearing plate 32 on the one hand and these parts with the head 13 of the Draw screw 12 must be ensured on the other hand. It can also be advantageous, the bottom bracket entirely, or in the case of a multi-part Bottom bracket at least parts thereof, on the respective pull screw 12 to arrange and fix or manufacture in one piece what their loss prevented as a relatively small item.
