Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • the invention further relates to a tubular body according to the preambles of claims 4 and 5 and to applications according to claims 7 and 8.
  • a smooth piece of pipe When manufacturing a sleeve, a smooth piece of pipe can be assumed, which receives an internal thread due to external deformation, the profile of which resembles that of a round thread.
  • the dimensions of the originally smooth-walled output part are dimensioned as a function of the dimensions of the mating thread onto which the sleeve is to be screwed, in such a way that there is a minimum clearance between the threads that can be brought into engagement with one another. It is particularly advantageous that the internal thread formed in this way can be produced in a single deformation step. Compared to a thread cutting process, the manufacturing costs of a socket with an internal thread can be significantly reduced.
  • the features of claim 3 have the advantage that the same working method can be used both for the production of the internal thread and for the production of the cooperating external thread, only the forming tool for the purpose of adaptation to the curved thread flanks of the internal thread and for adjustment a necessary game between the internal and external thread must be adjusted slightly.
  • the application of the method according to the invention is particularly advantageous in the production of connecting sleeves, which are used when coupling extension rods a rock bolt, a boring bar or the like are used.
  • connecting sleeves which are used when coupling extension rods a rock bolt, a boring bar or the like are used.
  • the connecting sleeve is solidified by the previous forming process and consequently has a high strength has an effect.
  • a round thread or a thread type similar to this must be used to ensure proper handling under the forthcoming operating conditions.
  • the manufacturing method according to the invention is associated with a flow of the material, it is naturally - without reworking the respective deformation contour - limited to the production of such thread types in which no acute-angled edges, such as with a metric thread, are to be created.
  • the entire outer contour thereof, including that of the connecting sleeve is expediently provided with threaded indentations, so that the outside discharge or washing away of the cuttings is facilitated in the case of narrow boreholes.
  • the use of the method according to the invention is also very advantageous in the production of connecting sleeves which are used in channel struts.
  • the fact that the connecting sleeves according to the invention can be of practically any length has a favorable effect here. In addition to good guidance of the threaded spindles, this also results in a wear-resistant design.
  • FIG. 1 denotes the end part of a rock bolt on the borehole side, which is also used as a boring bar.
  • This end part 1 is thus a tubular body, which carries a known drill bit 2 on its end facing the drilling base.
  • the drill bit 2 is provided in a manner not shown in the drawing with a central bore which serves to guide a flushing medium. This bore is in conductive connection with the interior of the end part 1.
  • the end part 1 or the tubular body 1 has a threaded section 3 which is connected to a V extension rod 5 via a connecting sleeve 4.
  • the extension rod 5 carries a threaded section 6.
  • the extension rod 5, like the end part 1, is designed as a tubular body. In principle, several such extension rods 5 can be placed next to each other and thus the total length of the rock anchor can be adapted to the respective requirements within wide limits.
  • the illustration of the section of the present rock anchor located in the region of the borehole end, to which a hammer drill or other drive unit is coupled during the drilling operation, has been omitted for reasons of clarity in the drawing.
  • the threaded sections 3, 6, which are designed as external threads, on the tubular bodies 1, 5 and the cooperating internal thread of the connecting sleeve 4, which is not illustrated in FIG enables easy handling.
  • the internal thread of the connecting sleeve 4 is produced by a non-cutting shaping, here by cold forming, in which the profile shown in FIG. 1 is produced by a deformation tool on the outside 7 of the connecting sleeve 4, the internal thread being formed by a to the outside profile complementary, internally effective material displacement is formed.
  • the outside 7 consists of a helically wound, approximately circular arc-shaped indentation 8 in cross section, with smooth, only slightly deformed surface sections 9 remaining between the individual indentation passages 8.
  • Fig. 3 shows that through the deformation process on the inside 10 of the threaded sleeve threads 11 are formed, the cross-sectional shape of which is essentially determined by arcs and which can thus be regarded as round threads. These threads 11 are directly opposite the indentations 8. It is essential for the subject matter of the invention that the formation of these threads 11 on the inside can be controlled at least so precisely, both in terms of the thread depth and in terms of the pitch, by the externally effective deformation that the threads 11 can function as an internal thread with respect to a predetermined external thread, which in the present case is formed by the threaded sections 3, 6.
  • Fig. 4 shows the effective thread pairing of the internal thread of the connecting sleeve 4 on the one hand and the external thread of the threaded portion 3 on the other.
  • the threaded sections 3, 6 are also produced by a cold-forming process and consequently have a profile which corresponds qualitatively to that of the outside 7 of the connecting sleeve 4.
  • connection sleeves of rock anchors In principle, it can be used with advantage in all those cases in which a tubular starting body has to be provided on the inside with a round thread or a comparable thread.
  • FIG. 5 shows an embodiment of a connecting sleeve 4, which can be used in a two-sided duct strut and is therefore provided with two different, namely counter-rotating, threaded sections 12, 13.
  • Threaded spindles are used in the end regions of this connecting sleeve 4 and are used in a manner known per se to support duct walls in civil engineering. These threaded spindles have an outer profile which essentially corresponds to that of the tubular body 1, 5 of FIG. 1, but these threaded spindles are not shown for reasons of clarity in the drawing are posed.
  • the connecting sleeve 4 is provided with an auxiliary device, also not shown in the drawing, for initiating a rotary movement.
  • this auxiliary device can be a bore into which a lever is inserted.
  • a nut or a molded tube can also be welded onto the connecting sleeve 4, which serves to initiate a rotary movement in connection with a corresponding tool.
  • a plastic nut can also be cast or pressed onto the outside of the connecting sleeve 4.
  • connecting sleeve 4 can be made practically indefinitely long with the internal thread produced according to the invention, there is a particularly reliable connecting sleeve which improves the buckling stability of the threaded spindles of channel struts. At the same time, the individual parts of the channel strut can be made relatively small due to the length of the connecting sleeve.
