Definitions

  • the invention relates to a method for producing fastening or connecting means with radial outer contours, in particular screws or threaded bolts, of solid metal material.
  • Screws or threaded bolts of diameters up to M36 consisting of metallic Voilmaterial are mass-produced in a manner known per se by the Kait extrusion method on multi-stage presses.
  • the hot pressing process is only suitable for small to medium quantities and diameters up to M200 and for materials that are difficult to form.
  • a method for the production of connecting screws for the furniture industry is known.
  • a rivet-shaped screw blank is produced by upsetting and extrusion in a multi-stage press with up to six stages. This is done in compression and extrusion stations by means of suitable ram, which interact with associated matrices.
  • the finished screw blank is then fed to a thread rolling machine, on which the thread is rolled up by means of Rolibacken.
  • the invention has for its object to provide a method for the production of fastening or Vietnamesesmittein with radial outer contours, in particular screws or threaded bolts, which enables more economical production, especially on a multi-stage press.
  • a prefabricated blank with a shaft-shaped portion, on which a certain radial outer contour, preferably a thread, is to be formed by one or more pressing operations is to be formed by one or more pressing operations.
  • the number of extrusion stages depends both on the blank and on the geometry of the final product.
  • a plurality of recesses extending in the axial direction are formed in the shaft-shaped section at a fixed radial distance.
  • the finished blank is inserted into a multi-part jaw tool with the jaws opened in the initial state in such a way that at least at the Steep, where the jaws are open, are located in the axial direction extending recesses.
  • the individual jaws of the pressing tool have on their inner side for forming the radial outer contour a corresponding réelleprofill für a negative.
  • the desired radiaie outer contour is pressed onto the shaft-shaped portion of the finished blank.
  • the recesses formed in the shaft-shaped section of the blank prevent material from passing between the jaws of the jaw tool during the pressing process. In the region of the recesses extending in the axial direction, no radial outer contour is produced during the pressing process
  • the recesses may be arcuate or semicircular. Their size depends on the size of the outer contour or thread to be formed. The depth should be slightly greater than half the difference between the outer diameter and core diameter of the outer contour or the thread to be formed.
  • the width of the recesses should be at least as large as the opening gap between the jaws, in the condition when the jaws are in touching contact with the blank.
  • fastening or connecting means with radial outer contours can be produced in a particularly economical manner.
  • Preferred field of application is the production of screws of all kinds and threaded bolts.
  • the threads can be designed differently in their geometry.
  • the term radial outer contours is to be understood as meaning other extrusions, such as threads.
  • Befestlgungs- or connecting means are those in question, which are screwed or einschlagbar. These include, for example, screw nails, groove nails, anchor nails or hooks.
  • the number of recesses formed in the shaft-shaped section and extending in the axial direction depends on the number of jaws of the jaw tool. In certain applications, it may also be appropriate to mold more recesses than jaws are present.
  • axially extending recesses can be formed in the shaft-shaped portion, whereby the blank is divided radially into six segments.
  • a jaw tool with three jaws is provided for the subsequent pressing of the radial outer contours.
  • the radial outer contours are then on the individual segments.
  • the shaft-shaped portion may be cylindrical or conical.
  • the conical design of the shaft takes place during one of the upstream pressing or compression stages within the multi-mare press.
  • the radial force component required for moving the jaws of the jaw tool can be generated by the applied pressing force of the slide arranged in the multi-stage press. This is an additional advantage, as can be dispensed with a separate drive for the closing and opening movement of the baking tool.
  • the axial prism force of the press carriage can be converted into a radial force component by means of one or more kell or cone-shaped elements which act on the jaws of the jaw tool. For this purpose, either the jaws or the kell- or cone-shaped elements are moved synchronously. To open the baking tool, the movement takes place in the opposite direction.
  • the blank before pressing the outer contour may be appropriate to heat the blank before pressing the outer contour, either strichwarrn, up to temperatures of about 700 ° C, or warm, to temperatures of about 1200 ° C.
  • the heating can take place directly in a heatable baking tool or in a separate upstream heating device.
  • the in the Fig. 1 Method stages I to IV, which are illustrated in a simplified manner, for the production of a hexagon socket screw in accordance with the invention take place within a multi-stage press, which is embodied as a rotary Drum press.
  • the non-illustrated multi-stage press has in known per se a machine frame with a sliding carriage 5 and a stationary tool carrier unit 6.
  • a shear tool 1 (process step 1) and two extrusion tools 2, 3 (process stages II and III) and a Thread press tool 4 (process step IV) arranged
  • the two Flleßpresstechnikmaschinegnee 2 and 3 each consist of a head die 2a, 3a and a Schaftmatrize 2b, 3b.
  • the head matrices 2a and 3a are arranged in the slidable carriage 5 and the opposite Schaftmatrizen 2b and 3b in the stationary tool carrier unit 6, wherein a reverse arrangement is possible.
  • the supplied as starting material wire 7 is cut to length in the process step I by means of the blade 1 and the cut wire section 8 by means not shown in detail gripper or transport device in the mold cavity of the Schaftmatrize 2 b of the first extrusion die 2 inserted.
  • the mold cavity of the shaft die 2b is limited in its depth by a first ejector 9 fitted in the shaft mast 2b.
  • a second ejector 10 is likewise arranged opposite to the first ejector 9, by means of which the mold cavity of the head die 2 a is delimited.
  • the inserted wire section is pre-compressed by a cold extrusion process in process stage II, forming a screw-head-like shape on the upper part of the wire section 8a.
  • the mold cavity of the Schaftmatrize 3b and the head die 3a is analogous as in the first extrusion die 2 by ejector 11 and 12 limited.
  • On the inner side of the Schaftmatrize 3b are three axially extending bead-shaped portions 24 (FIG. Fig. 2 ), which are intended for forming the axially extending recesses 13 in the shaft-shaped portion of the screw blank 8a during the Flleßpressvorganges in process step III.
  • the bead-shaped portions 24 are arranged at a defined radial distance from each other, since the recesses 13 must be located at least at the points where the jaws of the subsequent thread pressing tool 4 are open or close.
  • the preformed screw blank 8a is reshaped by another cold extrusion process in process stage III, whereby the screw head and the shank are given their final shape.
  • the upper ejector 11 which also serves as a ram, the hexagon socket recess in the head of the screw blank 8 a is formed.
  • the finished screw blank 8b obtained after completion of process stage III has a shaft with three identical recesses 13 extending in the axial direction, which are arranged radially at a distance of 120 ° from each other. After completion of the process stage III, the carriage 5 is moved back to its original position
  • this consists of an outer, axially displaceable ring 14, in which three jaws 15,16, 17 are mounted radially movable.
  • the jaws 15,16, 17 have on their inner side designed as a thread 18 Profill für a negative.
  • the outer ring 14 is guided on a kegelförmi lateral surface 19 of the jaws 15,16,17, which tapers in the direction of the opening movement of the carriage 5.
  • the outer ring 14 has a, corresponding with this, conical inner surface 20. In the open state of the baking tool 4, the outer ring 14 projects beyond the facing in the direction of the carriage 5 end faces of the jaws.
  • a projecting annular collar 21 is arranged in the carriage 5, which engages during the Zusteilterrorism of the carriage 5 at the adjacent end face of the ring 14.
  • the outer ring is moved in the axial direction, whereby the pressing jaws are moved 15,16,17 for pressing the thread in the radial direction.
  • the finished screw blank 8b is removed from the F widelypreaatechnikmaschine 3 by means of the ejector 10,11 and placed in the open jaw tool 4 by means of a gripper or transport device.
  • the screw blank 8b is positioned so that the three recesses 13 formed in the shaft are located exactly at the point where the pressing jaws 15, 16, 17 are opened (opening gap 25), as in FIG Fig. 3 shown.
  • a movable ejector 22 is arranged, which rests with one end in the hexagon recess of the screw head.
  • a further movable ejector 23 is arranged in the tool carrier unit 6, which rests against the end face of the shank of the screw blank 8b.
  • the carriage 5 For pressing the thread in the shank of the screw blank 8b of the carriage 5 is delivered, while the outer ring 14 is displaced and formed over the effected radial movement of the pressing jaws 15, 16, 17, the thread (26), wherein in the region in the axial direction extending recesses 13 during the pressing process no radial outer contour is generated.
  • the two ejectors 22, 23 retain their starting position during the thread pressing process and thus prevent an expansion of the screw blank 8b in the longitudinal direction during the pressing. Subsequently, the carriage 5 is moved back to its original position, the threaded press tool 4 is opened and ejected the finished screw.
  • the threaded press tool can also be designed differently in its design details. It is advantageous, however, if the opening and closing movement of the pressing jaws is realized via the movement of the carriage.
  • the individual process steps I to IV are synchronized in practical operation.
  • the individual pressing tools are z. B. arranged in alignment in a row
  • the number of the final thread pressing process upstream cold extrusion stages is dependent on the shape and geometry of the respective erhzusenden mounting or veneering agent.
  • the thread press tool can be equipped with an additional heating.
