Definitions
- the present invention relates to a method for producing a weight-optimized pneumatic tire rim according to the preamble of claim 1 and an apparatus for carrying out the method.
- Wall thickness which is only present in the finished tire rim in the claimed areas, is reduced accordingly by extrusion.
- the present invention is therefore based on the object of further developing a method of the generic type in such a way that the production times are shortened and thus less expensive production is possible.
- the pipe section used as a blank has, due to production, relatively large tolerances in its wall thickness, which hitherto resulted in extrusion to a predetermined wall thickness of the flanks to the aforementioned corners of the edges.
- the new process creates an exact, predeterminable volume of material that is available for the further processing of the flanks (length extension, contouring and bringing to predetermined wall thicknesses).
- the longitudinal extension, which results from the partial wall thickness reduction, which is carried out by means of pressure rollers, is preferably limited by a stop which is provided all around on the outer surface of the tool inner lining and against which the respective flank rests in the end position, i.e. after the end of the pressure roller ,
- the volume of the flanks that is defined after the pressure rolling means that their length can also be determined after the deformation has ended, taking into account the desired wall thicknesses.
- Wall thickness equalization pushed into the drop zone, where it leads to a wall reinforcement.
- the starting wall thickness of the pipe section can therefore be chosen to be less than the end wall thickness in the area of the deep bed zone, the
- the final thickness in turn results from the original wall thickness and the tolerance material of the flanks.
- the diameter of the cylindrical tube section is smaller than the largest outside diameter of the rim bed to be produced by the subsequent processing steps, whereas the diameter of the tube section corresponds to the largest diameter of the rim bed if the end-side expansion is dispensed with.
- a device for carrying out the method is designed such that a two-part tool lining, contoured on its outer lateral surface, is provided for receiving the cylindrical tube section, the two
- Tool lining parts are axially movable relative to each other.
- FIGS. 1 and 2 show a further exemplary embodiment of a device for carrying out a first method step in a schematic longitudinal section.
- This device has an inner tool chuck 2, which consists of a first chuck part 3 and a second chuck part 4, which can be moved relative to one another in the axial direction in a spring-loaded manner.
- the outer jacket of the inner tool chuck 2 is provided with a preliminary contour 5, into which the pipe section 1 can be correspondingly pressed by means of pressing / rolling rollers 8.
- FIG. 1 The beginning of the method can be seen in FIG. 1, in which the cylindrical tubular section 1 a lies on the outside of the tool chuck 2.
- the pressure-dependent alz rollers 8 are used to shift tolerance-related excess material of a certain specific, flank 6-forming, rotationally symmetrical region, with equalization of the wall thickness S1, into the region of a deep bed zone 7, from which the flanks formed on both sides 6 extend under the same wall thickness S2. Both the deep bed zone 7 and the flanks 6 assume the shape predetermined by the preliminary contour 5.
- the tolerance-related excess material leads to a thickening of the wall thickness S3 of the deep bed zone 7 compared to the original wall, while this is leveled in the area of the flanks 6 to such an extent that it corresponds, for example, to the lower tolerance measure.
- a thickness of 3.5 + _ 0.1 is given as the initial wall thickness of the tubular cylinder la, so that the wall thickness S2 of the flanks 6 is 3.4, while the wall thickness S3 of the deep bed zone 7 can be approximately 3.85.
- the equalization of the wall thickness in the area of the flanks 6 has led to a thickening of the deep bed zone 7 compared to the original use of material.
- both the first chuck part 3 and the second chuck part 4 have a circumferential stop 9, on which the pipe section la and then continue
- the precontoured rim base 1 is supported at the end in the course of the method.
- the second chuck part 4 is adjusted with spring force until it reaches an end position, as shown in broken lines in FIG. 1, and how it moves
- flanks 6 are further contoured while stretching outwards, as can be seen in FIG. 3.
- this device which has at least one pressing / rolling roller 8
- the respective different wall thicknesses of the flanks 6 can be produced.
- one of the two flanks 6, starting from the deep bed zone 7, is brought to a wall thickness S4 by means of the pressing / rolling roller 8, which presses from the inside out, which can be 2.6, for example, with reference to the previous dimensions.
- stops 9a are provided all around on the first and second chuck parts 3a and 4a and each form the end of the contour 5a.
- the height of the rim well 1 and the wall thicknesses of the flanks 6 can be exactly predetermined.
- the end regions of the flanks 6 are finished by shaping rollers 10.
- circumferential rim flanges 11 and bosses 12 are molded on, which serve to receive a tire.
- an inner tool chuck 2b which consists of a first chuck part 3b and a second chuck part 4b, the outside of which is at least partially shaped in accordance with the contour of the rim base 1.
