  • ABSTRACT A method for producing slant shoulder rims for tires including the steps of: forming a metal strip into a ring and welding a longitudinal seam to complete the ring.
  • PATENTEDNUV 12 m4 3l846L886 sum 30F 3 l METHOD FOR PRODUCING RIMS The present invention relates to a method of producing slant shoulder rims, so-called special rims; special rim produced in accordance with such method, and an apparatus for carrying out such method.
  • the conventional method does not permit shaping the rim base as a body of constant strength or as a special rim base having slants for guiding the tire.
  • the method according to the invention should be easy to perform and merely by using spinning machines, whereby the special rims according to the invention should be adapted to be produced with but two steps of operation.
  • the method according to the invention should lend itself to the fully automatic mass production of articles of minimum tolerances with a minimum of machine operation.
  • the apparatus according to the invention should be of simple construction, provide for troublefree operation, and as far as possible correspond to standard machines.
  • the above object is solved in that the special rim has such a wall thickness which is greater in the region of the snap ring groove, and smaller in the region of the rim base, than that of the wheel flange.
  • the wall thickness should correspond to that of a body of constant strength.
  • the method of producing the above-outlined special rims is characterized in that a ring is formed from a sheet metal or metal plate strip, the ring is welded along its longitudinal seam, one end of said ring is then thickened and has the profile of the snap ring groove drawn in at this location, whereupon the rim base is reduced in I thickness, and,
  • the wheel flange is erected, i.e. brought into an upright position by means of a spinning operation within an internal chuck.
  • An advantageous feature of the invention consists in that in order to draw in the snap ring groove, the edge of the workpiece ring is upset by a spinning operation with axial advance, whereupon the indentation of the groove is formed by a spinning operation with radial advance, whereby advantageously the outer wall of the groove is bent back after the drawing in of the profile of the snap ring groove.
  • the rim base is formed as a profile of constant strength by a draw spinning operation, whereupon the rim ring is clamped within an internal chuck and the wheel flange is erected by means of one or more rolls the surface shape of which corresponds to that of the wheel flange to be erected.
  • the edge may be cutoff after the erection of the wheel flange.
  • the apparatus according to the invention is advantageously characterized by a spinning machine having an external chuck for clamping the annular workpiece, a sleeve of said external chuck adapted to be moved beyond the end of said external chuck against a force, at least one cylindrical upsetting roll having a wide cylindrical surface, and at least one spinning roll for drawing in'the snap ring groove.
  • the apparatus further, comprises at least a pair of draw spinning rollers which also can be radially adjusted or advanced in continuous manner.
  • FIG. 1 shows the starting material bent into the shape of a ring and welded at the longitudinal edge thereof
  • FIG. 2 shows the ring accordingto FIG. 1 with an upset end
  • FIG. 2 a shows the snap ring groove drawn into the upset end
  • FIG. 3 shows the ring including the drawn in snap ring groove after the reducing of the rim base as a body of constant strength
  • FIG. 4 shows the finished special rim including the erected wheel flange
  • FIG. 5 is a schematical view of the spinning machine for upsetting the ring end.
  • FIG. 6 is a schematical view of the spinning machine of FIG. 5 for the drawing in of the snap ring groove and for the erecting of the outer wall of the snap ring steps, the material of the weld seam is integrated into As shown in FIG. 2, in a. first operation, one end of the rim ring is thickened; advantageously, such thickening may be performed in a spinning machine such as shown in the schematical view of FIG. 5. However, this thickened portion may be formed on the workpiece also by forging, hammering, cold or hot upsetting or swaging in a press.
  • the snap ring groove is then drawn by a spin rolling operation into the material of the thickened portion, whereby the outer wall 3 must be erected, i.e. brought to an upright position after the drawing in of the groove.
  • the rim base is stretched into a body of constant strength having slant shoulders with an inclination of 5 each, and the wheel flange is erected in a third operation as shown in FIG. 4.
  • the erection of the wheel flange is known from applicants prior German Pat. application P 20 53 005, reference being made to the disclosure of this prior application so that a detailed explanation of the erection of the wheel flange, within an interior chuck can be dispensed with at this point.
  • the edge 11 of the finished special rim may now be cut off.
  • the production of the intermediate shape according to FIG. 3 can be seenfrom the schematical view of FIG. 5.
  • the ring 1 is clamped onto an external chuck the outer end of which is formed complementary to the subsequently formed configuration of the thickened portion 2 of the snap ring groove.
  • a guide ring or a sleeve 8 is placed onto the external chuck which ring is forcefully urged in outward direction towards the end of the chuck. Now, when the spin rolls 9 which must have a wide cylindrical surface, are advanced towards the external chuck, they push the guide ring 8 in rearward direction, and the material of the ring 1 can now flow only inwardly into the space between the'extern'al chuck 7 and the guide ring 8.
  • the guide ring 8 is then withdrawn still further such that the spin rolls 10 may be advanced laterally into the region of the thickened portion 2.
  • the spin rolls 10 have a roll profile or crosssectional shape which is complementary to the profile of the snap ring groove. Then, the spin rolls 10 form the snap ring groove in conventional manner, whereby the outer wall 3 is again bent out to a certain degree. Therefore, during or after the forming of the snap ring groove the axial spin rolls 9 are advanced again so that they bend the outer wall'3 back into its desired shape.
  • a snap ring groove of this kind can be formed which is subject to minimum tolerances and the wall thickness of which may be thickened as desired, so that the desired strength values may be brought about in consideration of the notch stresses due to the production of the snap ring groove.
  • the wall thickness of the rim base 5 may be adjusted in the same manner as the wall thickness of the shoulders 4, independent of the wall thickness of the starting material.
  • the edge 11 of the final wheel flange will now have moved into a position remote from the snap ring groove.
  • the wheel flange is now erected in a further operation, whereby the material removed from the region of the rim base now forms the edge 11.
  • the special rim may be put into use in this condition; however, if it is desired to maintain precise weight tolerances of the complete special rim, the edge 11 may be cut off to conform to the designed shape.
  • any desired width of the special rim may be provided with any desired distribution of the wall thickness, without the material displaced from the region of the rim base resulting in an undesirable increase of the wall thickness at other places or even causing variation of the rim width.
  • the method according to the invention can be carried out by using for the most part customary draw spinning machines, whereby a guide ring 8 being slidable by spring force is placed onto an external chuck, which guide ring defines with the external chuck 7 a gap for receiving the rim ring 1.
  • the subsequent operations may be performed by draw spinning machines of conventional construction, too.
  • the method of the invention offers the further advantage that the wall thickness in the region of the wheel flangelikewise can be precisely adjusted by drawing the starting material which is present in the annular shape as shown in FIG. 1, to the desired thickness of the wheel flange prior to the further processing.
  • this first drawing operation will have no influence on the wall thickness of the snap ring groove and of the wheel flange. Accordingly, with the method of the invention it becomes possible for the first time to adjust all portions of a special rim independently from each other with respect to their wall thicknesses, without having to take into consideration the tolerances of the starting material.
  • step of drawing said snap ring groove comprises the further step of:
  • step of drawing the snap ring groove includes the further step of: bending back an outer wall of 'said snap ring groove after the spinning with the radial advance to after erecting the same.
