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 housing
- definable interchangeable mouthpiece for receiving an interchangeable pulling screw, with a holder which can be moved axially inside the housing, one end of which is designed for the rotationally fixed reception of an interchangeable driving mandrel and the other end protruding from the housing for the rotatable and releasable reception of a handle and for applying a key , with the free end of the respective driving mandrel for rotationally fixed
- Such tools are used for setting blind rivet nuts in thin-walled materials, e.g. B. sheets used, the strength of which is not sufficient to a thread
- the object of the invention is to improve a blind riveting tool according to the preamble of claims 1 and 2 in such a way that a safe, almost wear-resistant Interchangeable nuts are retained, even when high forces have to be applied.
- Fig. 2 interchangeable parts of the setting tool according to
- the setting tool 1 shown in FIG. 1 for setting blind rivet nuts in a thin-walled material has a tubular housing 2 which is conically tapered on the outside at the front end 3, and on the inside a stepwise reduction in diameter compared to the main part of the housing 2 having. In the end 3 there is thus a cylindrical cavity with a smaller diameter and in the main part a cylindrical cavity with a larger one
- an internal thread is embodied in the cylindrical section with a smaller diameter, into which a mouthpiece in the form of a screw sleeve 5 can be screwed with its external thread.
- Screw sleeve 5 (Fig. 2a) has a continuous central Inner bore 6 and a screw head 7 with an end face 8 for a blind rivet nut. On the external thread of the screw sleeve 5 is one
- non-slip handling and surfaces for engaging a tool e.g. B. has a wrench.
- the screw sleeve 5 may only be screwed so far into the thread of the housing end 3 that its screwed end maintains a - small - distance from step 10 (Fig. 1) between the cylindrical housing parts with different diameters.
- an inner bearing in the form of a support ring 11 is inserted into the housing 2, which is supported on the step 10. If necessary, it can be fixed in this position, e.g. B. insertable into a groove
- the central opening in the support ring 11 and the inner bore 6 in the screw sleeve 5 have a diameter that allows the passage of a pull screw 12 with little play. If the support ring 11 is not interchangeable
- Diameter which allows the passage of the screw part of the drawing screw 12 with the largest diameter.
- the head 13 of each draw screw 12 is to be supported almost completely on the support ring 11, so that there is a large contact area.
- the screw cap 16 is preferably designed so that its outer dimensions correspond to the outer diameter of the housing 2, with its surface
- non-slip e.g. B.
- B. can be designed by reefing.
- a holder 17 is arranged so that it can move axially and centrally within the screw cap 16.
- 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 cover 16 into the housing 2, is preferably cylindrical.
- a compression coil spring 19 is located on it
- a support e.g. B. supports a snap ring 20 which can be inserted into a groove 21 arranged in the region of the free end of the cylindrical holder part.
- a recess 22 is made, which is intended for rotationally fixed engagement with the second end of the driving mandrel 14 and the outline of which is adapted.
- the outer part of the holder 17 has a section for receiving a handwheel 23.
- the handwheel 23 is arranged removably on the holder 17, the corresponding section of the holder 17 also being cylindrical and having one or more projections (not shown) which have corresponding recesses in the edge of the hand 23 - at least in the end position of the up to the annular stop 18 postponed
- Handwheel 23 - can or can interact.
- the outer part of the holder 17 can also as a polygonal, for. B. hexagon mandrel (see FIG. 3h), onto which the handwheel 23 with a correspondingly designed central opening 24 (see FIG. 3j) can be pushed in a rotationally fixed manner.
- the outer part of the holder 17 has one over it
- the embodiment 25 is in the form of a hexagon (see the opening 24 in Fig. 3i).
- an end sleeve 26 (FIG. 3c, in plan view FIG. 3d) is in the front end 3 of the housing 2 in its internal thread
- Collar 27 can be screwed in, the collar 27 serving for support on the end face of the front end 3 of the housing 2.
- the end sleeve 26 ends before the step 10 in the fully screwed-in state.
- the end sleeve 26 has one
- Polygonal plug 29 with head 30 (Fig. 3a; in Fig. 3b in cross-section along line b - b shown in Fig. 3a) is adapted.
- the polygonal plug part 29 with the head 30 has an axial central through-opening 31 which serves for the passage of the pull screw 12 (FIG. 3f) and is adapted to its dimensions, as well as an end face
- the bottom bracket can also consist of one or more
- Bearing washers 32 exist and have a needle thrust bearing 33 (see. Fig. 3e), which serves to reduce the friction between the housing 2 and the head 13 of the pull screw 12 when the pull screw 12 for setting a
- This bottom bracket can also be fixed or replaceable.
- Bearing washers 32 as well as in the mouthpieces in the form of the screw sleeve 5, or the polygonal plug part 29 with head 30 by corresponding parts, each with an adapted Through hole or opening to be replaced.
- the bottom brackets are fixed and not interchangeable, they must allow the pulling screw 12 with the largest thread diameter to pass through. To prevent the heads 13 of the pulling screws 12 from slipping
- the replacement takes place in such a way that the
- Unscrewed screw cap 16 from the housing 2 and is removed from the housing 2 with the holder 17, which carries the driving mandrel 14 and the handwheel 23.
- the driving mandrel 14 can be secured against falling out by a snap connection, not shown, in the holder 17. Then the pulling screw 12 is also removed from the front end 3 of the housing 2, if necessary by pressure on it
- Polygonal plug part 29 is simply pulled out of the end sleeve 26, which remains fixed in the housing 2.
- the external dimensions of all polygonal plug parts 29 for all sizes of blind rivet nuts are identical to one another, so that the end sleeve 26 does not have to be replaced if a polygonal plug part 29 with a different diameter
- Polygonal plug-in part 29 with the respective pull screw 12 corresponding through hole 31 is inserted into the end sleeve 26. Then that, if applicable
- the bearing washers 32 with the needle pressure bearing 33 are supported on the step 10 and, if necessary, fixed, or with a fixed bottom bracket, an adapted reducer is on the respective pulling screw 12 is pushed on, after which the respective new pulling screw 12 is inserted from the cover-side opening of the housing 2 through the passages in the bottom bracket or mouthpiece until its head 13 or the reducing disk adjacent to it is supported on the bottom bracket.
- the holder 17 is equipped with a possibly also replaced driving mandrel 14, the free end of which is inserted into the head 13 of the drawing screw 12 for the rotationally fixed connection, after which the cover 16 is screwed on.
- the force for setting the blind rivet nuts can be transmitted by means of the handwheel 23, which otherwise also serves to unscrew a pulling screw 12 from the set blind rivet nut.
- the forces for setting can be applied by means of a ratchet or a screwdriver, which are attached to the extension 25.
- bottom brackets with the same passage diameter can be used for several sizes of drawing screws 12, which reduces the number of parts to be replaced, with a sufficient number
- Bearing washer 32 on the one hand and these parts with the head 13 of the drawing screw 12 on the other hand must be ensured. It may also be advantageous to arrange and fix the bottom bracket entirely or, in the case of a multi-part bottom bracket, at least parts thereof, on the respective pull screw 12 or to manufacture it in one piece, which prevents its loss as a relatively small individual part.
