Definitions
- the invention relates to a self-drilling fastener, consisting of a fastener body with an axially parallel slot formed at its one free end and a plate-shaped drill insert inserted at one end into the slot on the fastener body, the drill insert being deformed by the slot on the fastener body bounding jaws is positively and non-positively connected.
- a self-drilling screw is already known (DE-C-28 01 962), the drilling part of which is formed by a cutting insert inserted into a longitudinal slot of the screw shank, grooves being provided on the side edges into which the relevant edge area or partial areas the slit-limiting jaws of the screw shaft are pressed in to form a firm, positive and non-positive connection between the cutting insert and the screw shaft.
- the corresponding areas of the jaws are thus pressed into depressions on the surface of the platelet-shaped cutting insert until they rest on the bottom of this groove.
- the present invention has therefore set itself the task of creating a self-drilling fastener of the type mentioned, in which cutting inserts with greater axial length can be connected sufficiently firmly to the fastener body without additional welding, soldering or adhesive processes being necessary are.
- the end of the drill insert engaging in the slot on the fastener body has one or more notches, incisions, grooves or indentations on one or both of the lateral boundary surfaces, each of which extends over the thickness of the drill insert.
- the edge region of the jaw or the edge regions of both jaws of the fastener body is or are pressed in plastically deformed.
- the lateral tilting of the cutting insert during the drilling process is particularly problematic.
- the cutting insert is clamped on the two opposite narrow sides in a positive and non-positive manner between the jaws delimiting the slot, so that the cutting insert can no longer tip out sideways.
- the corresponding edge region of the jaws becomes plastic in the indentation which is continuous over the thickness of the drilling insert deformed pressed in, so that no resilient return is possible.
- Tests have shown that the measures according to the invention bring at least a doubling of the shear value.
- the present invention thus made it possible to use the platelet-shaped cutting inserts, which are optimal for a drilling process, also for drilling in relatively thick materials, without additional processing measures such as welding, soldering or gluing being necessary.
- the notches, incisions, grooves or indentations on both lateral boundary surfaces of the drill bit are arranged in mirror image to one another.
- the plastically deformed pressed-in areas of the jaws are therefore each at the same axial height, which is advantageous in terms of processing technology, since the feeding of the cutting inserts for the pressing process is easier, since the cutting inserts on both side edges are of the same design. It is also irrelevant whether an indentation or the like or two or more such indentations are provided on each of the two lateral boundary surfaces.
- the notches, incisions, grooves or indentations on both lateral boundary surfaces of the drill bit are arranged offset from one another. Then, in the manufacture of the self-drilling fastener, an orderly, correct feeding of the plate-shaped drill bit in accordance with the design of the corresponding pressing tool is necessary.
- the grooves start at a short distance from the end of the drill bit and extend over a large part of the length of the section of the drill bit inserted into the slot.
- the length of this groove which is limited at both ends, achieves an additional holding effect of the drill bit in the slot of the fastener body.
- the drill insert have at one end an extension with a smaller width, which engages centering in a central opening adjoining the slot in the fastener body.
- the drill insert already during the pre-assembly there is a centered alignment between the drill bit and the fastener body, which is then optimally secured by the pressing process.
- Figure 1 is an oblique view of a self-drilling screw.
- Fig. 4 is a front view of the same.
- the invention is explained in more detail with the aid of a self-drilling and tapping screw.
- the measures according to the invention can be applied to all self-drilling fasteners, e.g. also on self-drilling blind rivets, where the cutting insert is in operative connection with the rivet mandrel and / or the rivet sleeve, or with self-drilling dowels.
- the self-drilling fastener 1 shown in the drawing consists essentially of a fastener body 2 and a plate-shaped drill insert 3.
- the drill insert 3 is inserted into a slot 4 at a free end of the fastener body 2 and between the jaws delimiting the slot 4 5, 6 held positively and non-positively.
- the drill bit 3 has indentations 8 which extend through the thickness D of the drill bit 3 at its lateral boundary surfaces 7.
- the lateral edge areas of the jaws 5, 6 are deformed by a pressing process, partial areas of the jaws 5, 6 being plastically molded into the indentations 8 of the drill bit 3 and, so to speak, anchoring tabs 9 form.
- a corresponding notch 10 is visible on the surface of the jaws 5 and 6.
- this strip-shaped approach of the pressing tool results in easier deformability of the edge region of the jaws 5, 6. Therefore, lower forces are also necessary for the pressing process.
- the cutting insert 3 shown in the drawing also has grooves 1 1, 1 2 on both side boundaries on opposite surfaces 1 1, 1 2, such grooves 1 3, 14 also on both surfaces 1 1 and 1 2 on both sides, that is to say both Edge areas can be provided.
- grooves 13, 14 it is advantageous if they start at a small distance A from the end 15 of the drill bit 3 and extend over a large part of the length of the section of the drill bit 3 inserted into the slot 4.
- These grooves 13, 14 provide an additional improvement in the positive and non-positive connection between the fastener body 2 and the drill bit 3.
- an indentation 8 is provided on each of the two lateral boundary surfaces 7 of the cutting insert 3, these two indentations 8 being arranged in mirror image to one another.
- the indentations 8 are arranged on both lateral boundary surfaces 7 of the drill bit 3 offset in the axial direction. If a pressing tool is used, which has a rectilinear attachment surface, this means no additional effort for production, since the anchoring tabs 9 are produced by plastic deformation precisely where the corresponding indentations 8 are arranged. No special pressing tools are then required. Furthermore, it is then also not necessary to feed the drilling sets 3 exactly in position.
- the indentation 8 is delimited in the form of a circular arc in cross section. This is advantageous for punching reasons and also for a good engagement of the anchoring tabs 9 formed during the pressing process. Within the scope of the invention, however, it would also be possible to design the indentations 8 with a different cross-sectional shape or surface design or, for example, with a correspondingly greater axial length.
- a further design variant provides for the drill insert to be formed at one end 15 with an extension which has a smaller width than the other width of the drill insert 3.
- additional measures are then also required for the fastener body 2, i.e. that a central opening must be provided next to the slot in the fastener body 2, into which the extension of the drill bit 3 can then be inserted in a centering manner. This makes it possible to ensure a centered, axially aligned alignment of the fastener body 2 and the drill bit 3 even before the pressing process.
