Abstract
The invention concerns a bush which is made of high-pressure-resistant material, in particular metal, and is anchored in a bore in a component made of plastically deformable material, in particular a plastics component (10).
The bush comprises at least one hollow-cylindrical body and an outer flange region (14), the shape of the bore (11) matching the outer contour of the bush (12). The component is melted in the region of the flange (14) in order to secure the bush against rotation and/or in position.

Description
CA 02226~1~ 1998-01-07 r~ 'r- ~ WO 97/03297 Bush The invention relates to a bush of metallic material anchored in a bore of a component of plastically deformable material, especially a plastic component.
DE-GM 93 01 373 discloses a reinforcing bush. In the manufacture of an injectionmolding, this kind of reinforcing bush is anchored by insertion into the mold or is placed afterward in a bore. The bush disclosed in the German Gebrauchsmuster is anchored in a bore by upsetting it, that is, it is placed in the bore and upset with a punch to the ]ength of the bore. This change in length causes an expansion of the diameter of the bush and thus fastens it in the bore.
A disadvantage of this arrangement is to be seen in the fact that the mechanicaldeformation of the bush leads under certain cirC~ t~nces to ill-defined movements.
Moreover, reliable f~t~ning of the bush in the bore is assured only when the dimensions of' bush and bore are within very tight tolerances. This is not assured especially in the case of an injection molded plastic component.
Bushes are also known which are placed in a plastic component by so-called hot sinking method. For this purpose the bush is heated to a certain temperature andpressed into a bore in the plastic piece. The heated bush causes a local fusion of the plastic. But for this purpose the temperature of the bush must be set very accurately.
Too high a t~J~llpel~lule causes the plastic to burn. Too low a tel~lpel~ e causes insufficient fusion and may result in the rupture or spalling of the plastic.
German Patent 465 898 discloses a method for bonding metal parts to workpieces of plastic. Again, the metal part is heated and softens the plastic surrounding it, so that penetration of the metal part into the plastic is made possible.
A disadvantay;e of this method, however, is that the metal part floats in the soft plastic;
that is, it can perform uncontrolled movements leading to changes in the position of the metal part.
PCT/hl S ~ ~2215 WO 97/03297 The invention is addressed to the problem of avoiding the above disadvantages and creating a bush which can be anchored by simple means in a bore in a component.
This problem is solved by the principal claim.
The important advantage of the invention is that the bush needs neither to be heated nor upset or otherwise altered mechanically. After the bush has been placed in the bore with the hot punch, whose temperature can be established precisely, a portion of the plastic in the marginal area of the gush is fused and this molten plastic fastens the bush securely against twisting or change in position. The bush can thus be made in a very simple manner. Inaccuracies regarding the dimensions have no effect on the fixation.
Another advantage of the invention is that the cooling of the heated plastic by the withdrawal of heat through the bush takes place very quickly, so that a high proces.~ing speed can be achieved.
Another advantage is to be seen in the fact that the temperature of the hot punch can be set accurately and thus a more process-secure production is achieved.
It is furthermore advantageous that the bush can be inserted into the component without tools. This elimin~tes expensive assembly devices.
According to one embodiment of the invention the flange portion of the bush is provided with a hexagon. This has the advantage of achieving a positive connection between the plastic component and the bush.
Alternatively, the bush can be equipped with knurling on its circumference. Hereagain a positive connection can be achieved. To heat the plastic, a punch according to an advantageous embodiment of the invention is equipped with a heating cartridge.
This punch is provided with a Teflon coating. Both the temperature and the stroke of CA 02226~ i 1998-01-07 PCT/hl 9 .~2215 WO 97/03297 the punch can be established in a simple manner. The bush can be provided with athrough-bore, which advantageously is provided with an internal thread. The highsecurity against distortion assures that the screw thread function is reliably fulfilled.
These and other features of plef~lled embodiments of the invention will be found not only in the claims but also in the description and the drawings, wherein the individual features can be realized each by itself or severally in the form of sub-combinations in the embodiment of the invention and in other fields, and can be advantageous andindependently patentable embodiments for which protection is hereby claimed.
Embodiments of the invention are represented in the drawings and will be furtherexplained. The drawings show:
Figure 1 a plastic component with bush inserted, Figure 2 the bush fastened in the plastic component.
For the perm~nent fastening of plastic components it is necessary to insert bushes of metallic material. Such a plastic component is represented in a cutaway view in Figure 1. This plastic component 10 has a bore 11 which has a large diameter in the upper portion and a smaller diameter in the lower portion. A metal bush 12 is inserted into this bore. This metal bush contains an internal thread 13 and a flange portion 14. The flange portion 14 is in the shape of a hexagon. The depth of the larger diameter 11 is related to the bush such that the latter in its bottom portion projects slightly past the plastic component.
The plastic component 10 is fastened from the bottom to a supporting structure. The f~ct~ning is pcrformed by means of a screw connection. Of course, the possibility also exists of providing the bush with a through bore. In this case an additional nut is necessary for the screw fastening. The bush 12 can be inserted manually or CA 02226~1~ 1998-01-07 PCT/hl 9 C.'l' 1 S WO 97/03297 automatically into the plastic component 10.
Figure 2 shows a hot punch 15 with which the plastic of the plastic component 10 is heated in its upper portion. This hot punch 15 is Teflon coated to prevent adhesion to the plastic. The hot punch is moved in the direction of arrow 16 down onto the plastic component, h,eats the plastic with its front flanks, so that it flows in this area 17 and thus produces an axial fixation of the bush 12. The heated plastic also flows into the flats of the hexagon and thus secures the bush 12 against rotation. By setting the stroke length of the hot punch 15 the deptn of penetration of the plastic into the flats of the hexagon can be established. Thus prevention of rotation is set to an optimum value.
The possibility also exists, of course, of providing knurling on the bush in thecylindrical area 18. Thus the hexagonal configuration of the flange area 14 is unnecessary. This knurling also prevents the rotation of the bush 12. If the bore is already hexagonal in the upper portion, the prevention of rotation is already assured.
The melted plastic then provides only a secure positioning. Since this positioning does not need to absorb any forces, only a slight deformation of the plastic is necessary.
