Definitions

  • ABSTRACT Wheels are made by first forming a disk-shaped blank, forging the same into a semifinished wheel having a hub and a wheel disk surrounding the hub and having a peripheral rim provided with a cylindrical circumferential edge face, and then mounting the semifinished wheel in a machine.
  • the edge face is thereupon engaged with at least one pressure roller and split under application of pressure in direction inwardly of the edge face and towards the hub to obtain two unfinished flanges.
  • the unfinished flanges are rollingly deformed in opposite directions axially of the hub and to the desired configuration to thereby obtain two finished wheel flanges.
  • the present invention relates generally to a method of making wheels, and more particularly to a method of making wheels essentially without material-removing steps.
  • the profile roller is capable only of bending the existing flanges even if they are so configurated as to adequately be pre-deformed, and the juncture of the flanges with the actual wheel'disk constitutes a particularly critical region with respect to the material characteristics. In other words, it was not posible to obtain a 1 significant material deformation in direction normal to the roller pressure exerted by such a roller without danger that the material becomes warped. It follows from this that it is not possible under'these circumstances to form the wheel flanges with differential wall thickness or cross-sectional dimensions by the use of profile rollers in-accordance with the preceding approaches.
  • one feature of the invention resides in a method of making wheels, particularly wheels for automotive vehicles, which method comprises, briefly stated, the steps of forming a disk-shaped blank and forging the same into a semi-finished wheel having a hub and a wheel disk surrounding the hub and having a peripheral rim provided with a cylindrical circumferential edge face.
  • the thus semi-finished wheel is mounted in a spinning machine tool and its edge face is engaged with at least one pressure roller and split under the application of pressure in direction inwardly of the edge face and towards the hub to obtain two unfinished flanges.
  • the unfinished flanges are rollingly deformed in opposite directions axially of the hub and to the desired configuration to thereby obtain two finished wheel flanges.
  • Reinforcing ribs can be provided on the wheel disk at the same time, if desired.
  • the blank to be used in accordance with the present invention is provided with a single die with the necessary wheel dimensions and with a rim cross-sectionwhich is of substantially rectangular configuration-which guarantees the most advantageous material distribution from the point of pressure application and without incorporating any danger of fold and crack formation. The necessary control steps until the forged blank is mounted in a machine tool for further processing are thus significantly simplified.
  • the rim which according to the invention is of substantially rectangular cross-section, as mentioned before, is simply obtained with surprisingly precise manufacturing tolerances by adhering to the predetermined spacing between the halves of the die when the same are pressed together.
  • the customarily necessary removal of the flashing by sawing it off or resorting to material-removal processes, such as milling, produces an even cylindrical circumferential edge face in preparation for the subsequent pressure deformation steps.
  • the planar surfaces which extend normal to the cylindrical circumferential edge face are also smoothed at the same time.
  • the pressure roller or rollers for splitting the rim are moved radially against the cylindrical circumferential edge face and thereupon inwardly thereof to obtain the desired splitting, and simultaneously are also shifted axially with reference to the hub of the wheel so as to increase the width of the gap obtained on splitting. It is particularly advantageous if the pressure rollers used for the splitting step are shifted during their radially inward movement also in axial direction of the hub to such an extent that the aperture angle, the wall thickness and the relative position of the two unfinished flanges obtained as a result of the split all approach the desired values'which it is sought to obtain in the finished wheel.
  • the method can be further simplified by using the splitting rollers not only for the actual splitting step but also for the subsequent deformation of the unfinished flanges to their finished configuration of the wheel flanges.
  • the rollers are guided in known manner by the use of appropriate templates, and this directly results in the formation of the wheel flanges with desired cross-sectional differentiations.
  • FIG. 1 is an axial section through a first vehicle wheel
  • FIG. 2 is a view similar to FIG. 1 but illustrating a different second vehicle wheel
  • FIG. 3 is a fragmentary end-elevational view of FIG. 2, seen in the direction of the arrow III of that Figure;
  • FIG. 4 is a view analogous to that of FIG. 3 but seen in the direction of the arrow IV in FIG. 2;
  • FIG. 5 is a fragmentary cross section of the blank which is formed in a die and which constitutes the starting point for the method according to the present invention
  • FIG. 6 is a fragmentary cross section on an enlarged scale of the rim of the blank shown in FIG. 5;
  • FIG. 7 is a view similar to FIG. 6 but showing a first deformation stage in which the rim is split;
  • FIG. 8 is somewhat diagrammatic cross section of the same rim portion shown in FIG. 6 but illustrating a further defonnation stage subsequent to that shown in FIG. 7;
  • FIG. 9 is a view analogous to FIG. 8 showing still another deformation stage.
  • FIG. 10 is a view analogous to FIG. 9 but showing the final deformation stage.
  • the method according to the present invention provides for the manufacture of wheels without recourse to material-removing processes for the actual manufacturing operation, and regardless of the particular configuration of the particular wheel disk with hub or with reinforcing ribs.
  • Any desired configuration of the wheel flanges, particularly exteriorly reinforced wheel flanges can be obtained, as well as reinforcements which extend in parallelism with the wheel flanges and serve for a reliable retention and guidance of the tire if the wheel is for motor vehicles. All of this is obtained exclusively by the configuration of the die used in forging the original blank and the particular guidance templated used for guiding the pressure rollers with reference to the blank which is mounted in a machine tool.
  • the blank may be subjected to intermediate annealing if it is desired to at least partially reverse a hardening of the forged or rolled metal in order to reduce the force required for the defonnation.
  • FIG. 1 illustrates a relatively simple wheel 1 with reinforced wheel flanges 11, 11' and cross-sectional reinforcements 12 extending in parallelism therewith which guarantee a reliable retention and guidance of the tire between the wheel flanges l1 and 11.
  • the wheel 1 is assumed to consist of an aluminum alloy and it is produced from a cylindrical cast blank under the influence of heat and pressure to obtain a substantially bowlor plate-shaped blank with thickened rim.
  • the non-illustrated blank is formed in a two-part die to the final configuration of a wheel disk 3 of any desired shape with a hub 4 and an annular circumferential rim 5 of substantially rectangular cross section, analogous to the one shown in FIG. 5.
  • the cylindrical circumferential edge face 6 (again see FIG. 5) is then simply split radially by contact with a pressure roller in a machine tool, and the two thus obtained unfinished flanges are axially displaced with reference to the hub 4, and are rolled to the desired final configuration by pressure rollers which are guided in their movements by a guidance template until the desired rim-base configuration 10 (see FIG. 10) is obtained.
  • FIG. 2 A more complicated wheel 2 is shown in FIG. 2 and the individual processing steps of the present method are illustrated and explained in details in FIGS. 3-10 with reference to the wheel shown in FIG. 2. It will be appreciated that the necessary bores and configuration of the hub can be obtained without difiiculty, and do not form a part of the present invention.
  • the wheel shown in FIG. 2 is identified with reference numeral 2 and illustrated as being again a wheel for a motor vehicle. It is assumed to consist of a light metal, such as aluminum or the like, and is provided with wheel flanges 21 and 21' and reinforcements 22 which are analogous to the wheel flanges ll, 11' and the reinforcements 12 of FIG. 1.
  • the major difference between the wheel of FIG. 2 over that of FIG. 1 is in the very strong deformation-resistant configuration of the wheel disk 23, beginning at the hub 24.
  • FIG. 3 is a fragmentary and elevational view as seen in the direction of the arrow HI
  • FIG. 4 is a similar view but seen from the opposite side of FIG.
  • FIGS. 3 and 4 the wheel 2, or more particularly its wheel disk 3, has a very complicated configuration. The details of this configuration will not be further described because they do not form a part of the present invention; they are shown here only to indicate the complexity of shape which it is possible to obtain by resorting to the method according to the present invention, beginning with the formation of the blank in a forging step. It should be parenthetically pointed out that the bore 25 of the hub 24, and the bores 26 for securing the wheel, are produced in conventional manner, and that the contact surfaces 27 (see FIG. 2).are also produced and built in conventional manner.
  • FIGS. 5-10 show the steps according to the present invention by which the forged wheel blank shown in FIG. 5 is converted to the final wheel shown in FIG. 10, or again in FIG. 2.
  • the portions 28 do not undergo any changes whatever during the method according to the present invention.
  • the wheel disk 23 of the blank shown in FIG. 5 which latter has been produced by forging in a die as mentioned before, is clamped between two jigs or jaws of requisite configuration in a machine tool of known type and at this time it is advantageous but not necessary that the material corresponding to the spaces 29 in FIGS. 3 and 4 has already been removed because this facilitates handling of the wheel.
  • the machine tool is of known construction and those conversant with this art will also be conversant with thetype of machine tool in question. It utilizes one or several pressure rollers, and if there is more than one they are arranged in form of one or more pairs with the rollers of each pair being concentrically with reference to one another.
  • the single or several rollers are guided in known manner by a guidance template.
  • the operation of such pressure rollers controlled by guidance templates is already well known, and is for instance employed in forming cooking pots and utensils of aluminum; it produces clean surfaces of high dimensional accuracy.
  • rollers for the production of simple rope pulleys were already known as mentioned before, and the rollers were advanced radially inwardly with reference to the axis of the blank which was to be converted into a pulley. According to the present invention, however, it is now possible to use such rollers in a machine tool of the type under discussion directly for forming from a blank such as that shown in FIG. 5 and having a circumferential outer rim 5 of substantially rectangular cross section, to form the finished configuration shown in FIGS. 2 and 10.
  • one or several pressure rollers 17 are moved into contact with the outer cylindrical circumferential edge face 6 of the rim 5, and then radially inwardly with reference to the axis of the hub 24, to thereby split the rim 5 of FIG. 6 and obtain the configuration of FIG. 7, where two unfinished flanges 8, 18 are produced which are separated by a substantially V-shaped gap 7.
  • the roller or rollers 17 are advanced not only in radially inward direction towards the axis of the hub 24, but also in axial direction of the hub 24, by template control. Furthermore it has been found that at least during this stage of the operation it is advisable that the roller or rollers 17 be slightly inclined.
  • roller or rollers are displaced in axial direction of the hub 24 at the same time as they are displaced radially inwardly towards the hub 24, and the axial displacement is to such an extent that the aperture angle, the wall thickness of the unfinished flanges 8 and 18, and the relative position of the two unfinished flanges 8 and 18 at least approximate the desired values which are to be obtained in the finished wheel shown in FIGS. 2 and 10.
  • the next-following intermediate stage is shown in FIG. 8.
  • the roller 17 which is diagrammatically illustrated is advanced towards the left of FIG. 8, being inclined at the angle a with respect to the axis of the hub 24.
  • This causes the unfinished flange 8 to be deformed from the full-line configuration to the broken-line configuration which is identified with reference numeral 8.
  • the unfinished flange 18 is similarly deformed until, it assumes the configuration and position identified in broken lines with reference numeral 18, the second being utilized for this purpose (not illustrated); however, it is also possible to use a single roller 17 and to employ it first to deform one and thereupon other of the flanges.
  • FIG. 9 the next intermediate stage illustrated in FIG. 9 takes place.
  • a pressure roller 19 is used to deform the unfinished flange 8 from the brokenline position and configuration of FIG. 8 to the fullline position 8a of FIG. 9.
  • the flange 18' of FIG. 8 is deformed to the full-line position 18a of FIG. 9 by a second roller 19.
  • FIG. 10 shows the finished configuration 10 of the space between the finished wheel flanges 21 and 21'.
  • a pressure roller 20 is shown in FIG. 10 corresponding in its configuration substantially to the rollers 19, 19'.
  • the reinforcement 22 is illustrated having been produced by the successive steps of FIGS. 7-10. They extend in parallelism with the respective finished wheel flanges 21 and 21'.
  • the wheel flanges 21 and 21' are seen to be rounded, and this is advantageously accomplished by a material-removing process, such as milling, but it is again emphasized that all other forming steps are produced exclusively by template guidance of the roller 17 and/or the rollers l9, l9 and 20.
  • the mounting of the blank in the jaws or jig of the machine tool remains unchanged throughout the entire deformation process, and the configuration of the jaws or jigs used for the mounting and serving at the radially inner side of the flanges as a support and to counteract the pressures of the rollers 17, 19, 19' and 20, corresponds to the predetermined dimensions desired to be obtained and which are achieved stagewise and successively by the cold rolling deformation of the metal.
  • rollers 19, 19' were of different configuration from the roller 17, just as the roller 20 differs from both the roller 17 and the rollers 19, 19'.
  • these rollers 19, 19 and 20 can be replaced by a single roller 17 of necessarily slender configuration, and which is then not only continuously displaced axially of the hub but also inclined to difierent angles as needed to obtain the difierent material deformation.
  • roller or rollers 17 utilized for splitting the rim (see FIG. 7) exclusively in axial direction of the hub of the wheel, if they are inclined at such an angle with reference to the axis of the hub that during the splitting of the rim 5 substantially only one of the thus obtained unfinished flanges 8, 18 is continuously laterally (that is axially of the hub) deflected.
  • the advantage obtained in this case is that for all intents and purposes sliding friction of the respective roller with reference to the rim 5 occurs.
  • the invention can be practiced with blanks of different metals, including steel. If the metal is a light metal, such as aluminum or the like, the deformation of the material can be eased considerably by heating the same. Such intermediate annealing reverses cold hardening of the material and constitutes a reliable aid in preventing the formation of cracks in the regions of particularly high deformation of the material.
  • a circular cross section ingot of 180 mm diameter is produced in a continuous-casting installation.
  • the material used is the aluiminum alloy designated AlMgSil, which is somewhat analogous to the U.S. alloy 6061 but comprises 0.8% Mg, 1.1% Si, 0.3% Mn, 0.2% Fe, 0.1% Cu, 0.2% Zn, 0.15% Cr and 0.2% Ti.
  • the oxide layer on this ingot is removed by material-removing methods. Thereupon the ingot is subdivided into sections of 150 mm length and each having a weight of 10.3 Kg. The individual sections are heated to a temperature of 450 C. and warm pressed in dies of requisite configuration to obtain a plateor bowl-shaped blank having a thickened rim or edge.
  • This blank is already forged in the two-part die to the final configuration of the wheel disk 23 with the hub 24, as shown in FIG. 5. Subsequently, it is calibrated in a calibrating or straightening press. Now the areas 29 are removed in a duplicating milling machine to obtain correspondingly configurated empty spaces whereby not only the weight of the wheel is reduced but also the mounting of the wheel for all subsequent forming steps according to the present invention, and also for any material-removing steps is facilitated.
  • the rim 5 of substantially rectangular cross section with the cylindrical circumferential edge face 6 are milled to the intended diameter, for instance 35 mm thickness and 440 mm outer diameter.
  • the inner bore 25 of the hub 24 and the bores 26 for fastening of the wheel are produced in known manner and the abutment surface 27 shown in FIG. 3 is finished.
  • the semi-finished wheel now has the configuration shown in FIG. 5. It is inserted into a two-part chuck or jig whose jaws are tightly clamped with one another, for which purpose they extend through the respective spaces 29 into engagement.
  • This chuck is a part of a machine tool in which it is rotated.
  • the operational steps shown in FIGS. 7-10 are carried out by the radially and axially advanced pressure rollers, such as the rollers 17, 19, 19' and 20, which deform the material to the final finished configuration shown in FIG. 10. It is advantageous that several rollers concentrically operate and act upon the work piece at one and the same time. If the work piece is heated to a temperature of approximately 250 C, the manufacturing steps may be accelerated and the force required substantially reduced.
  • a set of three pressure rollers 17 is sufficient for carrying out the entire deformation process without having to change the positioning of the wheel with respect to the chuck.
  • each semi-finished wheel is first subjected to the initial deformation step shown in FIG. 7, and then moved to a second machine tool where the remaining steps of FIGS. 8, 9 and 10 are carried out.
  • a soft-annealing step at 450 C. with subsequent slow cooling is interposed before the respective wheel is transferred from the first machine tool to the second machine tool; this guarantees that in the second machine tool the unfinished flanges 8 and 18 can be deformed in cold condition in the manner shown in FIGS. 8-10 without fear of creating cracks or fissures in their material.
  • a method of making wheels, particularly wheels for automotive vehicles comprising the steps of forming a diskshaped blank; forging the same to obtain a semi-finished wheel having a hub and a wheel disk surrounding said hub and having a peripheral rim provided with a cylindrical circumferential edge face; mounting said semi-finished wheel in a machine tool; engaging said edge face and splitting said rim under application of pressure by a pressure roller in direction inwardly of said edge face and towards said hub to obtain two unfinished flanges; and then rollingly deforming by said pressure roller said unfinished flanges in opposite directionsaxially of said hub and to the desired configuration by moving said pressure roller axially of said hub, to thereby obtain two finished wheel flanges.
