    A method and apparatus for forming a profile groove in a key blank FIELD OF THE INVENTIONThe present invention relates to a method and apparatus forforming a profile groove in an elongated key blank having opposite side surfaces.
    BACKGROUND OF THE INVENTION AND PRIOR ARTThe normal way of forming profiles grooves in the sides of akey blank made of a durable material, such as brass, or so called “nickel silver", or some other metal alloy, is to usea rotating cutter disc which operates in a side surface ofthe key blank so that the material is cut away and a grooveis formed, while moving the axis of the cutter disc linearlyalong the key blank.
    However, the shape of the profile groove formed by such aconventional method is limited. Of course, the disc can beOriented at an angle relative to the key blank surface, andit is also possible to modify the shape of the peripheral,active surface of the cutter disc to some extent. Even so,there are numerous geometrical shapes of profile grooves thatneed other or additional forming methods, in particular un- dercut profile grooves of various geometrical shapes.
    It is known per se to use linearly guided punching tools with one or more teeth, such as broaches with several teeth, for making profile grooves in key blanks. See e.g. the published international patent application WO/2010/095997 (WINLOC AG), page 2, last paragraph. Such tools are guided and forced linearly in parallel to the key blank while forming a profile groove, such as an undercut groove.
    However, there are limitations as to the possible geometrical shapes that can be made with such punching tools. The forcesare very strong, and there is a clear risk that the materialof the key blade will start to float adjacent to the groovebeing formed in this way, especially if the wall between theinside of the groove and the outer surface of the key blankis relatively thin.
    Thus, there is a great risk that the key blade will be deformed during this forming process, making the finished key useless.
    OBJECT OF THE INVENTIONAgainst this background, it is an object of the invention toprovide a method and an apparatus that makes it possible touse linearly guided punching tools when making profilegrooves in key blanks, without deforming the material of thekey blank adjacent to the profile groove being formed in a surface of the key blank.
    It is also an object to provide a method and an apparatus forgroove making that is suitable for serial production of keys in large numbers, at relatively high speed.Furthermore, the method and apparatus should be reasonable in cost and easy to operate.
    SUMMARY OF THE INVENTION A method according to the invention, which overcomes the problems indicated above, involves the steps of - forming a profile groove in a side or edge surface of akey blank by means of a punching tool with at least onecutting tooth which is forced and guided longitudinallyin parallel to said elongated key blade so as to cut out the material of said key blank into the desired shape of the profile groove, corresponding to the cross-sectionalshape of said at least one cutting tooth, while- at the same time holding said opposite side surfaces of the key blank between opposite holding surfaces of afixture, including a firm abutment action on the longi-tudinal surface portions of the key blank located adja-cent to and all along said profile groove being formed,whereby the key blank material adjacent to said profilegroove is retained in a fixed state without being de- formed during the punching operation.
    Correspondingly, an apparatus according to the invention comprises - a longitudinally guided punching tool with at least onecutting tooth for forced movement longitudinally alongthe key blank and cutting out said profile groove in thekey blank during a punching operation, - a fixture provided with a guiding device for longitudi-nally guiding said punching tool during said punchingprocess, and - a holding device in said fixture, said holding devicehaving two opposite holding surfaces adapted to abutagainst two opposite side surfaces of said key blankduring said punching operation, including an abutmentaction on the longitudinal surface portions located ad-jacent to and all along said profile groove beingformed, whereby the key blank material adjacent to saidprofile groove is retained in a fixed state without be- ing deformed during said punching operation.
    Preferably, the punching tool is secured to a slide memberwhich is forced and guided rectilinearly in relation tothe fixture. The slide member may be guided in a longitu- dinal recess in the fixture, such as a cavity communicat- ing with a longitudinal passageway leading out to theholding surface of the fixture abutting against a side oredge surface of the key blank. The slide member may beprovided with a neck portion extending through such a pas- sageway and carrying the punching tool.
    The profile groove may be formed by a combination of proc-esses, such as an initial forming with a rotating cuttingdisc and a final forming with a punching tool. However, itis also possible to form the whole profile groove in one processing step by means of the punching tool.
    The punching tool may be provided with only one cuttingtooth, or be constituted by a broach having two or more cutting teeth.
    The profile groove being formed may be located in a side surface or in an edge surface of the key blank.
    These and other features of the invention will be apparentfrom the detailed description below and from the appended claims.

    DETAILED DESCRIPTION OF SOME PREFERRED EMBODIMENTS The apparatus shown in figs. 1 and 2 comprises a solidfixture with two clamping or holding members, viz. alower, stationary holding block 10, and an upper holdingblock 20, the latter being movable up and down so as toenable the positioning of a key blank 1 on an upper hold-ing or seating surface 11 of the lower block 10, andthereafter lowering the upper block onto the key blank andholding it firmly between the two blocks 10, 20. The lowerblock 20 has two side portions 12,13 extending upwardsfrom the seating surface 11 and forming between themselvesa chamber 14 in which the upper block 20 is movable verti- cally with a slight play. See also figs. 3A, 3B and 4.
    As appears from figs. l, 2 and 3B, the key blank l com-prises a flat key blade, with opposite side surfaces 2,3, and a grip portion 6.
    In the lower position of the movable block 20, as shown infigs. l,3A, 3B and 4, the movable block 20 is held firmlyso as to abut the upper side surface 3 of the key blank lwith a clamping or holding force (arrows A in figs.l,3Aand 4). This force does not have to be very great, but themovable block 20 should be maintained in its lower posi-tion so as to resist any tendency of the key blank to bemoved or deformed during the forming process. In this way,both opposite side surfaces 2, 3 (fig. 3B) of the keyblank l are maintained exactly in their initial states orpositions and will not be moved or deformed. This is espe-cially true for a ridge portion 8 of the key blank betweenthe side surface 2 and the undercut portion of the groove4. In order to achieve this, the upper block 20 may beconnected to a mechanism, such as a knuckle joint mecha-nism being structured in such a way that it will be main-tained exactly in its final operative position upon being lowered to its lowermost position.
    While being held firmly in its position between the twoblocks lO, 20, the key blank will be cut by a punchingtool 30 secured to a linearly guided slide member 40. Dur-ing the cutting process, a profile groove 4 is formed inthe key blank, adjacent to its first or lower side surface2. In this way, a pre-formed groove 4 of rectangular shapewill be extended sideways or downwardly (to the right infig. 3B) into an undercut groove portion 4a (fig. 8C). So,the preformed groove 4 is made by a conventional rotatingcutting disc, whereas the undercut groove portion 4a is made by means of the linearly guided punching tool 30 ac- cording to the present invention. The rectangular profile groove 4 and its adjoining undercut portion 4a are clearlyvisible in the figures 7A through 7E (the groove 4) and 8Athrough 8E (the undercut portion 4a which stands at right angle to the rectangular groove 4 in this case). See espe-cially figs. 8C and 8E. The undercut portion 4a, which is also rectangular in shape, adjoins the groove 4 at some distance from the bottom of the relatively deep groove 4 and is relatively wide at its innermost part.
    The undercut portion of the groove 4a extends only alongthe key blade up to the stopping step surface 5 near thegripping portion 6, along a length Ll. Thus, in this em-bodiment, the undercut portion 4a will end with a distinctstep surface inside the profile groove 4, whereas the re-maining profile groove will end with a curved portion,corresponding to the shape of the cutting disc used whenforming the rectangular initial groove 4. The innermost,undercut portion 4a of the profile groove may be used toachieve an axial stop, cooperating with a correspondingrib with a limited length in an associated key plug of a cylinder lock (not shown).
    In this embodiment (figs. l, 2, 3A, 3B, 4), the punchingtool 30 is provided with one cutting tooth only, at theend of the tool 30 (to the left in figs. l, 2 and 4).
    The forces appearing when cutting the key blade by thepunching tool 30 are very great, and it is imperative thatthe key blank is held firmly between the blocks 10,20 andalso that the linear guidance of the slide member 40 isvery precise. The exact guidance of the slide member 40 isaccomplished by way of machining or otherwise forming a longitudinal cavity l5 in the lower block l0 (fig. 3A), l0 the cavity extending in parallel to the upper seating sur-face ll of the block l0 and to the longitudinal axis ofthe key blank upon placing the latter onto the seatingsurface ll between the upstanding side portions l2, l3 ofthe lower block l0. Also, the cross-section of the slidemember 40 corresponds exactly to the configuration of thecavity l5, with only a slight play enabling a linear butnon-rotatable movement of the slide member 40 within thecavity l5. A non-shown drive mechanism will push the slidemember longitudinally in the direction of the arrow B(figs. l and 2) with a great force, in order to carry outthe cutting process of the punching tool 30. The drivemechanism may be constituted e.g. by a mechanical drivemechanism, an electro-mechanical drive mechanism, a pneu-matic drive mechanism, or a hydraulic drive mechanism, aswill be selected by those skilled in the art of general machinery.
    The punching tool 30 must be firmly secured to the slidemember 40, and this is achieved by a longitudinally ex-tending neck portion 4l which is adapted to connect theslide member 40 with the punching tool 30 and which fitswith a slight play in a longitudinal passageway l6 (figs.l and 2) formed in the lower block l0 adjacent to the cav-ity l5. The cavity l5 has a substantially rectangularcross-sectional configuration, with rounded edges, whereasthe passageway l6 and the corresponding neck portion 4lhave an upwardly tapering cross-section that will ensure astrong and durable connection to the punching tool 30.Preferably, the slide member 40 and the cutting tool aremade in one piece, but it is also possible to weld or screw them together. ll In fig. 3B it will be seen that the upper, cutting part ofthe punching tool 30 is formed with the same cross-sectional configuration as the desired cross-section of the undercut portion 4a of the profile groove.
    In case the profile groove 4 is to be provided with a fur-ther undercut portion, it is feasible to use a modifiedpunching tool having at least one further tooth having aconfiguration corresponding to the desired shape of thefurther undercut portion 4aa, as shown in figs. 8A', 8B',8C', 8D' and 8E'. The further undercut portion 4aa adjoinsan undercut portion 4a corresponding to the undercut por- tion 4a in the previous embodiment.
    In this case, the profile groove 4 extends along the wholelength of the key blade and along the major part of thegripping portion 6, along a total length L2 up to a holein the gripping portion.
    Another key blank is shown in figs. 8A", 8D” and 8E”.Inthis case, the profile groove 4 with its undercut portion4a extends along the full length L3 of the key blank l,including the gripping portion 6 thereof. Here, the cross-section of the profile groove is the same all along the key blank, as will be seen in figs. 8A” and 8E”.
    In figures 5 and 6, there is shown a modified embodimentof the groove forming apparatus including an upper, mov-able block 20' and a lower, stationary block lO' config-ured to receive a key blank l (oriented lying flat on aseating surface ll' as in figs. l and 2) between tworather shallow upstanding side portions l2', l3' and witha projecting portion l7 fitting into a hole 9 in the gripportion 6 of the key blank. l2 The height of the upstanding side portions l2', 13' issubstantially the same as (or slightly less than) thethickness of the key blank l, so that the key blade l willbe firmly held in place by the upper block 20' when thelatter is pressed down. Then, the planar lower surface(not visible in figs. 5 and 6) clamps onto the key blank land possibly also onto the lower block 10' (arrows A in fig. 6).
    The structure and function of the punching tool 30 and theslide member 40 are the same in this embodiment as in theprevious one. The only difference is the configuration of the two blocks lO, 20 and lO', 20', respectively.
    Of course, a key blank formed as described above is not afinished key. Rather, as is well-known in the art, itshould be provided with some code pattern cooperating withtumblers in an associated cylinder lock (not shown). Suchcodes can be formed e.g. along the profile groove, so asto cooperate with side tumblers in the lock, and/or at alongitudinal edge 7, as shown in figs. 9A and 9B (wherethe edge cuts will cooperate with regular tumbler pins in a lock).
    As indicated above, it is also possible to form an under-cut profile groove in one manufacturing step by using abroach having a number of cutting teeth. Various resultingkey blanks are shown in figs. llA through llE, figs. llA'through llE' and figs. llA”, llD” and llE”, the profilegrooves being formed in one step in a key blank l' asshown in figs. lOA through lOE and having no initial pro- file groove at all. Accordingly, the whole profile groove l3 is formed in one step with a broach being forcedly guided along the key blade l'.
    Depending on the shape of the profile groove, the broach30' is provided with a number of teeth 3l', 32', 33', 34',etc. (see figs. 18A' and l8C'), where each successivetooth is displaced or extended somewhat in relation to theprevious one. In this way, each tooth will cut away an ad-ditional amount of material in the key blank, and a rathercomplicated geometrical configuration can be obtained.Compare also the end view in fig. l8B' showing the com- plete configuration or contour of the profile groove.
    An advantage with the embodiment shown in figs. l7,l8A,etc is that the profile groove can be manufactured in one step, which makes the production quicker and less costly.
    The invention may be implemented in various ways. An al-ternative groove making apparatus is shown in figs. 12 and13. The main difference in relation to the embodimentsshown in figs. l, 2, 5 and 6 is that the movable block 20”is moved sideways (arrows C) against an upstanding portion13” of the stationary, lower block 10” and that the keyblank is oriented with its central plane standing verti-cally. Here, the profile groove is formed in the loweredge surface of the key blank l. It is important that theopposite side surfaces of the key blank adjacent to itslower edge, are held firmly in place all along the edgesurface in which the profile groove is being cut by means of the punching tool.
    Otherwise, this apparatus, with the slide member 40 andthe punching tool 30, operates basically in the same way as in the previous embodiments. l4 Although not shown in the drawings, the cavity 15 whichguides the slide member 40 may be formed as an open recessin the lower block lO, preferably with undercut side por-tions serving to hold the edge portions of the slide mem-ber in place vertically, or it may be a circumferentiallyclosed cavity. In the latter case, the key blank will haveto be inserted into the cavity as well, possibly togetherwith an insert member fitting precisely into the cavitytogether with the key blank. In such a case, there will beno movable block of the fixture, other than the insertmember which is positioned axially into the cavity. Itseems more practical, however, to have two blocks, one ofwhich is movable vertically or transversely in relation to the other.
    It may be possible to use a fixture with only one blockhaving a recess at the top, with a seating surface for one(lower) side of the key blank, and longitudinal grippingteeth or ribs which engage with portions of the other (up-per) side of the key blank. The risk of floating materialon this upper side is lower, so such a fixture may also beuseful, at least in case the profile groove in said one(lower) side of the key blank is rather shallow, e.g. less than half of the thickness of the key blade.
    The key blank l may have a grip portion 6a, as shown infig. 14A (and in the other drawing figures of the embodi-ments described above), or it may have a base portion 6bor an extended portion 6c of the key blade which may beattached to a separate gripping member 6, as shown infigs. 16A, l6B and l6C. In either case, the key blank la, lb, lc may be provided with a profile groove 4 by means of an apparatus and a method as described above (before at- taching the gripping separate member).
    The exact shape of the profile groove may be selected asdesired. There may be minor irregularities in the cross-sectional configuration, and it is also possible to leaverather thin walls between an undercut portion of the pro-filed groove, internally of a ridge portion, and the ex-ternal side of such a ridge portion (which may form a part of side surface of the key blank).
    In particular, it is possible to form profile grooves hav-ing any geometrical shape as disclosed in the interna-tional patent application published in WO20lO/096009(WINLOC AG) .
    Thus, the inventive method and apparatus will give a widefreedom in designing new keys for cylinder locks, with oneor more profile grooves with or without an undercut groove portion.
    Also, with a broach having a multitude of teeth, it ispossible to cut a complicated shape of a profile groove ina single manufacturing step, which makes the productionquick and not very expensive, at least when producing large number of key blanks.
