Definitions

  • the invention relates to a method for producing a connecting element with at least two spherical sections, with two spherical sections directly adjacent to one another or with two spherical sections being connected to one another by means of a connecting section, the rolling of an at least partially cylindrical blank between at least two rolling tools and the shaping of the at least two spherical sections and optionally the connecting section is provided during rolling.
  • a connecting element with two spherical sections is from the German published application DE 10 2011 087 286 A1 known.
  • the spherical sections directly adjoin one another.
  • the connecting element should be manufactured very simply and cost-effectively from mass-produced individual balls that simply need to be connected to one another.
  • the individual balls can be connected to the connecting element, for example by welding.
  • Clip elements are then placed onto the spherical sections, which in turn are connected to one of the components to be connected to one another. It is intended to line up more than two balls to form a connecting element.
  • a method for producing a connecting element with at least two spherical sections is known, with two spherical sections being connected to one another by means of a connecting section.
  • the connecting element is produced by rolling a cylindrical, one-piece blank between at least two rolling tools. During rolling, at least two spherical sections and at least one connecting section are produced.
  • the invention is intended to provide an improved method for producing a connecting element.
  • a method for producing a connecting element with at least two spherical sections is provided, with two spherical sections directly adjacent to one another or with two spherical sections being connected to one another by means of a connecting section, in which the rolling of an at least partially cylindrical, one-piece blank between at least two rolling tools and the shaping of the at least two spherical sections and optionally the connecting section are provided during rolling.
  • a connecting element with at least two spherical sections can be produced by a single cold forming process.
  • the welding of the spherical sections to the connecting element can therefore be omitted and both the spherical sections and the connection of the spherical sections are produced in a single operation.
  • by rolling a cylindrical blank it is possible to achieve a very large degree of deformation, so that the two spherical sections can be formed.
  • the connecting element produced according to the invention can thereby reliably fulfill its intended function, namely being locked with a clip element.
  • Roll rolling tools or two flat rolling jaws can be provided.
  • the blank is preferably circular cylindrical.
  • the blank can be separated from a wire coil by the rolling tool or a separate separating device. This makes handling the blank easier.
  • the spherical shape can deviate from a spherical shape and, for example, rotationally symmetrical shapes can be produced, which are, for example, more bulbous than balls and can therefore, if necessary, provide more material for pressing operations.
  • This can be advantageous if the spherical sections are pressed directly into through openings in sheets and, to secure the press-in position, projections are pressed out of the spherical section, which then protrude from the spherical section above and below the sheet.
  • the shaping takes place over the course of 10 to 15 revolutions of the blank.
  • connecting elements can be produced quickly and in large quantities.
  • the connecting elements can be made from a blank without waste, i.e. without slugs.
  • a slug is separated from the outer ends of the spherical sections at the end of the rolling process by means of a separating edge on a rolling tool, the separating edge extending beyond the central longitudinal axis of the connecting element.
  • slugs are usually created that absorb excess material from the blank that is not required for producing the connecting element.
  • a slug is created, for example, by the fact that the blank must first be held at one of its ends when it is inserted into the rolling tool.
  • this slug or two slugs at the opposite ends of the almost finished connecting element can then be separated automatically by means of a separating edge on a rolling tool. In this way, the connecting element can be manufactured entirely by rolling and, as a rule, no further processing is required.
  • the blank is held at least before the start of rolling on a feed head of the blank, the feed head being disk-like and protruding in the radial direction beyond the blank, which is cylindrical with the exception of the feed head.
  • Such a disk-like feed head makes it easier to hold the blank before rolling begins and thus also makes it easier to insert the blank into the rolling tool.
  • the feed head is separated together with the separation of one of the slugs.
  • the connecting element can therefore be completely finished using a single rolling process.
  • the blank has a circular cylindrical base body.
  • the blank can, for example, be designed as a piece of wire and in particular a disk-like feed head can be produced by upsetting the piece of wire.
  • two flat rolling jaws are provided as rolling tools.
  • the connecting element can be manufactured in large quantities and with tight tolerances.
  • each flat rolling jaw has two trough-shaped recesses which widen and deepen in the intended rolling direction.
  • the two flat rolling jaws are displaced relative to one another, with the blank being accommodated between the flat rolling jaws.
  • the blank then rolls on the two flat rolling jaws and is thereby deformed at the same time.
  • the forming takes place gradually from the cylindrical, in particular circular cylindrical, blank to the spherical sections through the widening trough-shaped recesses. As stated, approximately 10 to 15 revolutions of the blank are sufficient to completely form the connecting element.
  • the two trough-shaped recesses are separated by means of a central web running parallel to the intended rolling direction.
  • a constriction is formed between the two spherical sections of the connecting element during rolling and thus the relative movement between the blank on the one hand and the two flat rolling jaws on the other.
  • a connecting section can be formed between the two spherical sections using the central web.
  • a connecting element with at least two spherical sections is produced, with two spherical sections directly adjacent to one another or with two spherical sections being connected to one another by means of a connecting section, in which the connecting element is produced from a one-piece blank by means of rolling between at least two rolling tools.
  • Two spherical sections directly adjoin one another and are separated from one another by means of a constriction, with a diameter of the connecting element at the thinnest point of the constriction being between a third and half of a diameter of the spherical sections.
  • a rolling tool for producing a connecting element using the method according to the invention has two flat rolling jaws, each flat rolling jaw having two trough-shaped recesses which widen and deepen in the intended rolling direction.
  • the two trough-shaped recesses are separated by a central web that runs parallel to the intended rolling direction.
  • At least one of the trough-shaped recesses is provided on its side opposite the central web, at least in an end section with the greater width and depth of the recess, with a separating edge which extends beyond a central longitudinal axis of the connecting element produced in order to separate a slug.
  • separating edge By means of such a separating edge, it is possible to simultaneously separate the slug during the last revolution or the last revolutions in the rolling process. For example the separating edge extends beyond an angle of 180° for spherical sections. So if the almost finished connecting element, on which the slug is still hanging, is moved into the area of the separating edge, the separating edge ensures that the slug is separated as the almost finished connecting element continues to roll on the two flat rolling jaws.
  • the central web has a substantially constant width over the entire length of the respective flat rolling jaw.
  • Fig. 1 shows a side view of a blank 10 for producing a connecting element using the method according to the invention.
  • the blank 10 has a circular cylindrical base body 12 and a disk-like feed section 14.
  • the disk-like feed section 14 projects in the radial direction beyond the circular cylindrical base body 12.
  • the feed section 14 serves to hold the blank 10 while the blank 10 is being fed to a rolling tool and, if necessary, to guide it during the start of the rolling process.
  • the feed section 14 is automatically separated at the end of rolling in the method according to the invention. This will be explained below.
  • the circular cylindrical base body 12 is formed during rolling into two spherical sections of the connecting element and optionally a connecting section between the two spherical sections.
  • a slug is formed at both ends of the circular cylindrical base body 12 during rolling, see Fig. 3 , which absorbs excess material and is automatically separated at the end of rolling.
  • Fig. 2 shows a top view of a flat rolling jaw 16 for use in the method according to the invention.
  • two identical flat rolling jaws 16 are used, which hold the blank 10 between them and are then moved relative to one another.
  • the blank 10 then rolls on the flat rolling jaw 16, in Fig. 2 from left to right, and is simultaneously formed between the two flat rolling jaws to form the connecting element according to the invention.
  • Forming is carried out by rolling and, as a result, by cold forming.
  • the flat rolling jaw 16 has a base body 18 in the form of an elongated cuboid, see also Fig. 4 .
  • Two trough-shaped recesses 20, 22 are provided in the top of the base body 18, which are located in the intended rolling direction Fig. 2 So from left to right, widen and deepen.
  • the two trough-shaped recesses 20, 22 are separated from one another over their entire length by a central web 24, see also Fig. 4 .
  • the central web 24 has a constant width over the entire length of the flat rolling jaw 16.
  • the inner edges of the trough-shaped recesses 20, 22, which are formed by the central web 24 in both the trough-shaped recess 12 and the trough-shaped recess 22, are therefore parallel to one another.
  • the respective outer edges 26, 28 however, run in the intended rolling direction Fig. 2 so from left to right, apart.
  • ribs 30 arranged one behind the other are arranged outside the side edges 26, 28.
  • the ribs 30 each form a driving track, which, however, only extends parallel to the trough-shaped recesses 20, 22 between approximately a third and half of the length.
  • the ribs 30, which form the driving tracks serve to take the blank along at the start of the rolling process, so that it does not slip relative to the flat rolling jaws 16, but rather rolls on the flat rolling jaws 16.
  • the blank 10 is completely formed into the connecting element 40 in the course of approximately 10 to 15 revolutions relative to the flat rolling jaws 16 Fig. 3 is shown, transformed.
  • the side edges 26, 28 of the flat rolling jaw 16 are designed as separating edges and extend over the central longitudinal axis of the blank 10 or the almost completed connecting element 40.
  • the completed connecting element 40 and its central longitudinal axis 42 can be seen.
  • a slug 44, 46 can be seen above and below the connecting element 40, the one in Fig. 3 upper slug is still connected to the feed section 14.
  • the slugs 44, 46 form outside the trough-shaped recesses 20, 22, since excess material is displaced from the trough-shaped recesses 20, 22 and flows into the slugs 44, 46. These slugs are when the blank 10 reaches the area of the end section 32 of the trough-shaped recesses 20, 22, see Fig. 2 , still connected in one piece to the blank 10.
  • the connecting element 40 has a first spherical section 46 and a second spherical section 48, which each have the same diameter and are separated from one another by a constriction 50.
  • the two spherical sections 54, 56 are connected to one another in one piece in the area of the constriction 50, since they were formed by cold forming during the rolling of the blank 10.
  • the diameters of the two spherical sections 54, 56 are the same size and the diameter in the area of the constriction 50 is approximately one third to half the diameter of the spherical sections 54, 56.
  • the connecting element 40 is used to connect two workpieces.
  • the two workpieces are each connected to a clip element which has a spherical recess that fits the spherical sections 54, 56 and consists of an elastically resilient material, for example a suitable plastic.
  • the spherical section 54 of the connecting element 40 is then clipped into the clip element of the first workpiece and the spherical section 56 into the clip element of the second workpiece.
  • the two workpieces are then securely connected to one another via the connecting element 40.
  • the constriction 50 is formed between the two spherical sections 54, 56 of the connecting element 40 during rolling through the central web 24.
  • the central web 24 is pressed into the cylindrical base body 12 of the blank 10 and displaces material to the left and right into the spherical sections 54, 56 while the blank 10 is rolling on the flat rolling jaw 16.
  • FIG. 4 The representation of the Fig. 4 is schematic. During rolling, the blank 10 lies between two flat rolling jaws 16, with an upper flat rolling jaw for the sake of clarity Fig. 4 is not shown.
  • Fig. 4 shows schematically the state in which the connecting element 40 is already completely formed and the connecting element 40 is thus located in the end section 32 of the trough-shaped recesses 20, 22, cf. Fig. 2 .
  • the slugs 44, 46, cf. Fig. 3 has already been completely separated.
  • the side edges 26, 28 extend in the end region 32 beyond the central longitudinal axis 42 of the connecting element 40.
  • the connecting element 40 can be completely formed in a single rolling process. At the end of this rolling process, the slugs 44, 46 are separated so that the connecting element 40 is then completely finished.
  • FIG. 5 shows a schematic, sectional top view of a rolling tool 60 according to a further embodiment of the invention, with only one in the illustration Fig. 5
  • Flat rolling jaw 64 lying under a blank 62 is shown.
  • the flat rolling jaw 64 is essentially identical to the flat rolling jaw Fig. 2 educated.
  • the blank 62 does not have a feed section and is rather separated to the required length at the beginning of the rolling track of the flat rolling jaw 64 from a supplied wire 66, for example from a wire coil, by means of a schematically shown cutting tool 68.
  • the cutting tool 68 can be designed, for example, as a pair of scissors, a saw or the like.
  • the wire 66 is fed from a wire coil, for example.
  • the blank can be easily inserted between two flat rolling jaws of the rolling tool 60. Only when the end section of the wire 66, which later forms the blank 62, is correctly positioned relative to the rolling tool 60 and specifically, see Fig. 5 , at the beginning of the rolling path the flat rolling jaws 64 is arranged, the blank 62 is separated from the remaining wire 66 by means of the cutting tool 68.
  • Fig. 6 shows a sectional side view of a rolling mill train 70 according to a further embodiment of the invention.
  • the rolling tool 70 has a lower flat rolling jaw and an upper flat rolling jaw 74, which can be designed identically to one another and which accommodate the cylindrical blank 62 between them.
  • the blank 62 can, as shown in the Fig. 5 was explained, form the free end of a wire 66.
  • the two flat rolling jaws 72, 74 are each provided with a separating edge 76, 78, which are intended to separate a piece of the wire at the beginning of the rolling movement and thereby form the blank 62.
  • the lower flat rolling jaw 72 is moved to the left and the upper flat rolling jaw 74 is moved to the right.
  • a height of the separating edge 76 of the lower flat rolling jaw 72 increases Fig. 6 from left to right and a height of the separating edge 78 of the upper flat rolling jaw 74 increases Fig. 6 from right to left. If the two flat rolling jaws 72, 74 are in Fig.
  • the blank 62 When moved horizontally to the left or right, the separating edges 76 and 78 penetrate into the material of the wire and at the respective higher end of the separating edges 76, 78 the blank 62 is then completely separated from the wire.
  • the blank 62 therefore does not have to be held by separate devices but is used as a free end of a wire into the in Fig. 6 Position shown between the two flat rolling jaws 72, 74 moves. If the flat rolling jaws 72, 74 then according to in Fig. 6 If the arrows shown are moved to the left or right, the blank 62 is already clamped between the flat rolling jaws 72, 74. After the blank 62 has been separated from the wire, the blank 62 is then held securely between the two flat rolling jaws 72, 74.
  • Fig. 7 shows a schematic, sectional plan view of a connecting element 80 according to the invention and an end section of a flat rolling jaw 72.
  • the flat rolling jaw 72 is identical to the flat rolling jaw 16 of the Fig. 2 educated.
  • the connecting element 80 according to the invention is made from a blank 62 without waste, cf. Fig. 5, Fig. 6 , manufactured.
  • the blank 62 is formed into the connecting element without the formation of slugs.
  • the blank 62 can be used, as in the 5 and 6 is shown, for example cylindrical and designed as a section of a wire 66.
  • FIG. 8 shows schematically another connecting element 90 according to the invention
  • Fig. 8 Lower spherical section 92 is designed to be more bulbous in the middle region than the upper spherical section.
