Definitions

  • the invention relates to a clothes hanger consisting of a hanger body made of wood, plastic or the like. And a hanging hook that is bent from a profile wire, preferably a round wire, provided at its end with a groove-like profile, each with a groove shoulder projecting beyond the circumference of the profile wire, and by Driving this end is attached to the bracket body.
  • a profile wire preferably a round wire
  • the grooved profile In order to obtain a sufficient pull-out force, the grooved profile must be designed in such a way that, at least in some areas, there is an outer diameter larger than the wire diameter, so that the profile grips like a barb in the bow body.
  • the grooved shoulder is therefore shaped so that it projects beyond the wire diameter, a fir-like profile usually being selected. This profile is obtained in that the grooves are rolled or rolled in at an angle to the wire axis, the material being displaced outwards and each groove shoulder as an annular cutting edge projecting beyond the wire diameter.
  • This manufacturing technique requires a rotary movement of the tools and / or the suspension hook as well as corresponding clamping devices.
  • the entire forming process consists exclusively of displacing the material from the round cross section into the desired profile shape, so that the flow of the material is an essential prerequisite for the forming process.
  • the tools eat up due to cold welding processes at high piece output, on the other hand, the material is often torn open on the groove shoulder protruding from the round wire, so that an unclean surface is created.
  • the first-mentioned process leads in particular to considerable wear on the tools, which increases progressively with the working speed or the piece output.
  • the performance of such forming machines is usually up to 60 pieces / min. Outputs of 100 pieces / min are also possible, but this leads to uneconomically high tool wear.
  • the invention has for its object to provide a hanger of the structure described above so that a cheaper production of the suspension hook is possible while maintaining the known high pull-out forces.
  • the profile is formed from non-circumferential grooves, the groove base of which runs linearly and essentially follows a secant of the wire cross section and which have different depths over their length.
  • the profile provided according to the invention on the suspension hook therefore does not consist of circumferential grooves of constant depth, but of grooves running linearly and transversely to the wire axis, which follow approximately one second with respect to the wire cross section and have a different depth over their length. At their tapered ends, the grooves can merge into the essentially uninfluenced surface of the profile wire.
  • This design of the profile allows the grooves to be produced by means of linearly moving tools with an extremely short stroke, as a result of which the working speed can be considerably increased compared to the forming by rolling or rolling processes.
  • the grooves are - depending on the material of the bracket body and the desired pull-out force - only partially provided on the circumference, for example on only one or on opposite sides of the profile wire, wherein the grooves on one side can optionally be axially offset with respect to the grooves on the other side , it is always only important that the grooves have a linear groove base in order to be able to produce them by simple lifting movements of the forming tools.
  • Profile wire is primarily understood to mean not only round wire with a circular or oval cross section, but also wire with an angular cross section, even if the latter is only used in special cases.
  • each groove consists of several, preferably four sections, the bottom of which forms an inscribed rectangle, preferably a square, with respect to the wire circumference.
  • groove sections are thus arranged over the entire circumference of the round wire, each forming a groove.
  • Several such grooves are arranged at an axial distance from one another.
  • the necessary barb-like formation of at least one groove shoulder can be obtained - as in the known manufacturing technology - by forming tools placed at an angle to the wire axis.
  • the end of the profile wire is flattened on opposite sides and is provided with the grooves on at least one of the remaining sides.
  • the grooves can of course be arranged on both remaining opposite sides, optionally also at an axial distance from one another. It is also advantageously provided that the width of the flattened end is greater than in the undeformed area of the profile wire, the grooves being provided in the wider area. With this profiling, because of the greater width in the area of the profile, there is a barb-like design of the groove shoulders from the outset, it not being necessary to provide an oblique arrangement with respect to the wire axis.
  • the invention further relates to a method for producing a hanging hook for a hanger of the aforementioned construction.
  • This process is characterized in that the grooves are produced by punching and embossing tools that move linearly and transversely to the profile wire.
  • stamping and embossing tools can now achieve forming speeds that are hardly possible with any other forming process.
  • multiple tools can also be used, which lead to a further increase in performance.
  • the forming process in the method according to the invention essentially consists of an embossing which is preceded by a kind of punching by correspondingly sharp embossing edges, that is to say a cutting process in which the flow behavior of the material does not represent the sole decisive role for the material behavior in the forming process.
  • the material is displaced and the groove shoulder protruding over the circumference of the profile wire is preserved.
  • tools with a combination of cutting and non-cutting forming will be selected here.
  • each groove of the profile consists of several groove sections with different inclinations, for example the bottom of these sections forms an inscribed rectangle or square
  • two counter-rotating tools with angled cutting edges are used according to the invention, each about half Grip over the circumference of the profile wire.
  • the entire profile is thus generated by counter-rotating tools with a very short stroke, with the machined material between the two tools.
  • Each tool consists of a group of cutting edges arranged at an angle to each other.
  • the wire end according to the other embodiment of the invention has a flattened end
  • this and the profile of the suspension hook are produced according to the invention in that the profiled wire is initially flat-pressed at one end transversely to its axis and then displaced the grooves on the outside during compression Pages are generated by punching and embossing tools moving in the same direction.
  • the profile is attached at a small distance from the free end of the profile wire, with the result that an undeformed section remains at the end of the wire which, after the suspension hook has been driven in, ensures that it is adequately guided within the bow body , so that the hook cannot wobble despite the regionally greater width of the hole remaining when driving in above the profile.
  • the suspension hook shown in Figure 1 is made of a round profile wire and has a substantially part-circularly curved hook part 2 with a slightly outwardly bent end 3 with an upset ball head and a shaft 4, at the end of which a profile 5 for fastening the suspension hook 1 through Driving into a bracket body, not shown, is provided.
  • the profile 5 at the end of the shaft 4 of the suspension hook 1 can be seen in more detail in one embodiment in FIGS. 2 and 3. It consists of a plurality of grooves 6 arranged at an axial distance from one another, which in this exemplary embodiment consists of four around the circular circumference of the shaft 4 consist evenly arranged groove sections 7. As can be seen in FIG. 3, these groove sections 7 have a linear groove base 8, which runs transversely and at an angle to the axis of the round wire of the suspension hook. This results in a different groove depth over the length of the groove.
  • the grooves 6 are also introduced into the round wire in such a way that a groove shoulder 9 which projects beyond the diameter of the shank 4 is formed by displacing a part of the material outward from the groove during the shaping.
  • the groove sections are produced essentially by punching and embossing tools with cutting edges running at an angle to one another. These stamping tools with simultaneous embossing action are driven linearly in one stroke movement, two counter-rotating tools with angularly arranged cutting groups being provided for the exemplary embodiment shown in FIGS. 2 and 3. so that during a tool stroke the shape shown in FIG. 3 arises, in which the groove base 8 of the groove sections 7 essentially forms an inscribed square with respect to the diameter of the shaft 4.
  • the end of the shaft 4 is flattened, so that the shaft 4 has flats 10 on opposite sides.
  • the material of the shaft 4 is displaced to the side by the upsetting, so that the shaft in the regions 11 has a greater width than its diameter.
  • grooves 6 are again formed by means of linearly moving punching and embossing tools, only punch cuts being sufficient in the areas 11 due to the greater width present there, so displacement of the material to the outside is not necessary, since the barb-like effect in the area the widening is guaranteed.
  • the shaft 4 of the suspension hook 1 is generally driven in deeper than the profile 5 is high, so that it is completely recessed, a hole is formed in the upper part of the bracket body in accordance with the wire diameter of the shaft 4, i. H. the suspension hook is no longer guided in the area immediately above the profile 5 and adjacent to the flats 10 and could wobble after a corresponding period of use.
  • the profile 5, as can be seen in FIG. 4 is arranged at a distance from the shaft end, so that this shaft end remains cylindrical and forms an additional guide in the bracket body, which prevents the suspension hook from wobbling.
