Definitions

  • the invention relates to a method of manufacture of hinge part blanks from rolled or drawn Strip material, which in the preamble of claim 1 Art.
  • DE-OS 42 32 211 describes a process for the production of Hinge part blanks made of strip material known in which from a rolled strip material with sheet cross-section by successively cutting off um Hinge part blanks arranged 180 ° apart their common contact line and their transverse boundary lines manufactured a large number of hinge part blanks become.
  • the known method has the disadvantage that only relatively simple hinge parts are made can, especially those where the two hinge parts to each other are complementary and this through Punching can be cut from a sheet metal strip material can.
  • EP-OS 0 603 018 describes a process for the production of Hinge part blanks made from rolled or drawn strip material known with profile cross-section, in which by successive, waste-free cutting of the parallel ones Hinge part blanks along their transverse Boundary lines a variety of hinge part blanks getting produced.
  • the rolled or drawn strip material has a profile cross section that the corresponds to both hinge part blanks in a parallel arrangement, with these two hinge part blanks through a point with a reduced cross-section is related to one another, the following the successive cutting is broken to separate the two hinge part blanks to separate.
  • This known method also has the disadvantage that only relatively simple, complementary interactions Hinge parts can be manufactured.
  • the object of the invention is a method for the production of hinge part blanks made of strip material such to improve that complicated hinge part blanks by cutting off by 180 ° or mirroring and staggered hinge part blanks along their common line of contact and their transverse Boundary lines can be made, respectively one half of the hinge part is completely independent special one deviating from the second half of the hinge part Can have shape.
  • this object is achieved by a process for the production of hinge part blanks made of rolled or drawn strip material, which in the preamble of claim 1 explained type in the characterizing part of claim 1 measures taken become.
  • first strip material has a cross section has the two rotated by 180 ° or mirror image and put nested blanks of one Hinge part corresponds to a second strip material has a cross section that rotated two by 180 ° or mirror images and staggered blanks of the other hinge part and the waste-free Cutting the respective two strip materials through two- or three-dimensionally controlled beam cutting along the common contact lines and the outer boundary lines can be done in a simple manner, even more complicated Hinge part blanks are made as they are in particular for door hinges on motor vehicle bodies are required in which in addition to the pure hinge function functions to limit the opening angle and the like must be provided.
  • the common contact line in one hinge part is designed with a projection, one with the other hinge part cooperating, the opening movement limiting stop provided and in that other hinge part with the larger, angled projection the bend is designed such that this Hinge hole for the one rotated by 180 ° or mirror image and offset nested hinge part the special nesting enables and on the other hand in the angle achieved a desirable gain.
  • Fig. 1 is a door hinge 1 for a motor vehicle door with its one hinge part 2 on an end wall of the vehicle door 3 and with its other hinge part 4 on one Longitudinal wall of the vehicle body 5 by means of appropriate fasteners (7) attached.
  • the two hinge parts 2 and 4 are together via one Hinge pin 8 pivotally connected, which in known Way arranged and can be formed.
  • the first, door-side hinge part 2 consists essentially from a flat mounting leg 10, an angled Hinge leg 11 with a thickening 12 and one projecting stop nose 13.
  • a receiving bore 14 for the Hinge pin 8 arranged in the thickening 12 .
  • the other, body-side hinge part 4 consists in essentially from a flat mounting leg 16, with a thickened bend 17 and a hinge leg 18 with a thickening 19 for receiving a receiving bore 20 for the hinge pin 8.
  • FIG. 2 is the three-dimensional view of the hinge 1 1, from which it can be seen that the hinge pin 8 with its lower section 21 rotatably in the Bore 20 in the thickening 19 of a hinge part 4 is arranged and with its upper portion 22 rotatable in the bore 14 in the thickening 12 of a hinge part 2 is rotatable. Further training of the hinge pin 8 does not need to be explained in detail, since this is known Way with a bearing sleeve with a lubricant supply and the like can be provided.
  • 3 and 4 is rotated and offset by 180 ° arranged nesting of two hinge parts 2 or 2 ' seen the rolled or drawn strip material 24 in profile form.
  • Fig. 3 is the direction of the cutting beam by the arrow ST specified that for a cutting machine with 2D control is applied.
  • a cutting machine with a 3D control device runs in the direction of the cutting beam ST as indicated in dashed lines always normal to the acted upon Surface.
  • FIGS. 5 and 6 the one rotated by 180 ° or mirror image staggered nesting of the hinge parts 4 and 4 'can be seen that the rolled or drawn Strip material 30 results in profile cross section.
  • Fig. 6 are the contact lines with arrows I and the boundary lines marked with arrows II.
  • the arrow ST shows the direction of the cutting beam with a 2D cutting machine, whereas those in dashed lines Lines shown arrows ST the direction of the cutting beam specify if a 3D cutting machine is used.
  • FIGS. 3 and 5 shown profile cross sections of the rolled or drawn Strip material of course not on the one shown here Embodiment are limited, but that a variety of contours are possible and appropriate, if there is care is taken that a nesting is rotated by 180 ° or a mirror image is possible and shared Leads contact lines.
  • For waste-free cutting required nesting of the hinge part blanks is particularly the case on the body-side hinge part thereby achieved in a favorable manner by the profile cuts two hinge parts projected one above the other be that the the mounting holes for the hinge pin forming thickenings in the bend of each other part, see Figures 5 and 6. Only this Procedure allows one of the required final component contour appropriate nesting and waste-free cutting with complicated hinge shapes. This leads to material accumulation in the area of the bend, which however is desirable is because the greatest bending moment and the highest bending stress occur.
  • the hinge part blanks are manufactured by waste-free Cutting, preferably using a blasting process.
  • Two jet cutting heads drive under consideration the feed rate numerically controlled the Component contours and so put directly from the strip material the final hinge part blanks in profile cross-section forth, then only with regard to the required Holes for receiving the hinge pin and Machined further details that may be required Need to become.
