Definitions

  • a method for producing a metal part of a plastic - metal composite part and a metal part produced by the method is to produce a metal part of a plastic - metal composite part and a metal part produced by the method.
  • the invention relates to a method for producing a metal part, wherein the metal part is provided on its outer circumference with a plastic part, in particular with a gear made of plastic, nylon or the like, and a metal part produced by the method.
  • Such gears made of plastic, nylon, etc. with a metal part are used in large numbers in the manufacture of cars, trucks, etc. Areas of application include u.a. the steering aids in such vehicles.
  • the metal part is equipped with a bearing, such as bearings.
  • the knurls on the outer diameter can be formed as knurls with axially parallel grooves, as cross knurls, as left - right knurls or the like.
  • Another disadvantage is the cost-intensive production by a machining of the metal part in both methods.
  • the invention is therefore an object of the invention to produce a generic metal part more cost-effective and to improve the positive connection.
  • the invention also relates to a metal part produced by the process.
  • the metal part may for example also be used for rollers of a roller conveyor, wherein the roller body is made of plastic.
  • thermoformable sheet with the name StW24-DD13.
  • StW24-DD13 thermoformable sheet with the name StW24-DD13.
  • Figure 1 shows a perspective view of a metal part 1.
  • Figure 1a shows the metal part 1 from below and Figure 1b, the metal part 1 from above.
  • the metal part 1 consists of an outer periphery 2 with a knurling, which is formed here as a knurl with axially parallel grooves, a flange 3 and a cylindrical receptacle 4, on the outer diameter 5, for example, the ring of a bearing (not shown) is pressed.
  • the attachment of the ring of the bearing can also be done by other means.
  • FIG. 2 shows a metal part 1 according to FIG. 1a. The difference lies in the knurling mounted on the outer circumference 2, here in the form of a knurled knurl.
  • a spherical depression 7 is introduced into the board 6 according to FIG.
  • a hole 8 arranged centrally in the spherical recess 7 can already be introduced in a previous step or following the recessing process.
  • Einziehradius is provided in the recess at an outer diameter of the receptacle 4, for example, 35 mm R 5 in the recess.
  • the spherical recess is formed by drawing or deep drawing to a cone portion 9.
  • the cone portion 9 is formed in one or more steps, again by pulling or deep drawing, to a cylindrical receptacle 4, as shown in Figure 5.
  • the outer circumference 5 and the height 10 of the receptacle 4 are reduced or reduced. This results in a thickening of the material and / or a hardening of the material in the region of the receptacle 4.
  • the pull-in radius 11 of, for example, R5 is calibrated to a radius R 0.5.
  • the flange 12 is bent or crimped in accordance with Figure 9 by 90 ° downwardly, wherein the outer collar 13 is preferably designed cylindrical.
  • an axially parallel knurling is then applied in the next step.
  • the grooves of the axis-parallel knurling are produced by material displacement.
  • the metal part 1 is taken up with the inner contour 14 according to FIG 10 and pressed by a ring whose inner shape corresponds to the profile of the grooves.
  • the material displaced from the metal part 1 is distributed in the edge region, for example, by a further upsetting or calibrating process and, if necessary, is displaced. solidified.
  • the material displacement for generating the grooves of an axis-parallel knurling can also take place from both edge regions 20, 21.
  • the displaced material is displaced towards the middle of the height of the outer diameter 5 and the grooves 16 are formed.
  • the displaced material forms approximately in the middle of a circumferential web 15th
  • a first variant of a further embodiment provides that the circumferential web 15, with respect to the flange 3, is formed on the upper edge region 20 of the collar 13 (FIG. 10 a).
  • a second variant of a further embodiment provides that the circumferential web 15, with respect to the flange 3, is formed at the lower edge region 21 of the collar 13 (FIG. 10b).
  • a metal part 1 with such a web 15 has the advantage that the overmolded plastic jacket, nylon jacket or the like can not slip off the grooves 16 that the plastic material, nylon material or the like surrounds the web 15 from both sides or one side.
  • the web 15 may have an outer diameter 22 which is equal to or larger than the outer diameter of the grooves 16.
  • the position and the diameter and width of the web 15 is influenced by the force or forces acting on the plastic jacket, the nylon jacket or the like, which can act from different directions.
  • the metal part 1 at the lower edge of the collar 13 has a sealing lip 17 and the inner diameter of the receptacle 4, a further sealing lip 18.
  • the arrangement is shown in FIG.
  • the sealing lips prevents injection molding material enters the metal part 1, especially on the inner contour 14.
  • the transition between the flange 3 and the receptacle 4 can be designed so that a contour 14 is formed which is similar to an undercut.
  • a contour 14 is formed which is similar to an undercut.
