Definitions

  • the invention relates to a method for producing fastening or connecting means with radial outer contours, in particular screws or threaded bolts, of metallic solid material, and a device intended for carrying out the method.
  • Screws or threaded bolts with diameters up to M36 consisting of solid metal material are mass-produced in a manner known per se by the cold extrusion method on multi-stage presses.
  • a so-called multi-stage press several tool units consisting of punch and die and auxiliary tools are arranged, in which the individual forming operations in a defined order, stepwise, are performed.
  • a screw blank starting from wire material e.g. three compression stages required: compression, pre-forming of the screw head, final formation of the screw head. After the third stage, the finished screw blank is available.
  • the external thread is formed in a subsequent separate process by thread rolling or thread rolling without cutting. The surface of the threaded part is plastically deformed by the action of radial forces.
  • 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.
  • the invention has for its object to provide a method for producing fastening or connecting means with radial outer contours, in particular screws or threaded bolts, which enables a more economical production, in particular on a multi-stage press. Furthermore, a device suitable for carrying out the method is to be provided.
  • a prefabricated blank having a shaft-shaped portion on which a certain radial outer contour, preferably a thread to be formed.
  • the number of extrusion stages depends both on the blank and on the geometry of the final product.

  • the finished blank is inserted into a multi-part jaw tool with jaws that are open in the initial state, so that recesses extending in the axial direction are located at least at the locations where the jaws are open.
  • the individual jaws of the pressing tool have on their inner side for forming the radial outer contour a corresponding inner profiling as a negative.
  • the recesses may be arcuate or semi-circular. 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, when the jaws come into touching contact with the blank.
  • 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 may be formed in the shaft-shaped portion, whereby the blank is radially divided 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 Training of the shaft takes place during one of the upstream pressing or compression stages within 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 pressing force of the pressing carriage can be converted into a radial force component by means of one or more wedge-shaped or conical elements which act on the jaws of the baking tool. For this purpose, either the jaws or the wedge or conical 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 expedient to heat the blank before pressing the outer contour, either half-warm, 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.
  • a device suitable for carrying out the method is preferably designed as a multi-stage press which has a fixed tool carrier unit and a slide movable in the direction of the tool carrier unit, and at least one extrusion tool and a downstream baking tool with at least two radially movable pressing jaws which have a negative side on their inner side have radial profiling.
  • the extrusion die consists of a head die and a shank die, with the shank die on the slide and the head die opposite to each other on the tool carrier unit.
  • the shaft die has on its inner side at least two bead-shaped sections extending in the axial direction, which are arranged radially at the same distance as the opening gaps between the pressing jaws of the jaw tool.
  • the device in particular the jaw tool, is equipped with locking elements which prevent longitudinal expansion of the blank located in the tool during the closing movement of the pressing jaws.
  • the jaw tool is connected to a drive unit for the radial movement of the pressing jaws in the closed and open position in conjunction.
  • the jaw tool can also be equipped with its own drive unit. However, in terms of machine technology, it is advantageous if the radial movement of the pressing jaws in the closed and open position is triggered by the movement of the carriage.
  • the jaw tool can be arranged either on the tool carrier unit or the carriage. Similarly, the arrangement of head die and Schaftmatrize the extrusion tool can be changed.
  • an actuating element On the carriage or on the tool carrier unit is an actuating element, via which the radial displacement of the pressing jaws can be triggered.
  • the jaw tool preferably consists of an outer ring in which the pressing jaws are mounted radially displaceable, wherein the lateral surfaces of the pressing jaws and the inner surface of the ring are conical or wedge-shaped, such that upon axial displacement of the ring or the pressing jaws, the pressing jaws In Closing and opening position are movable.
  • the ring is stationary and the jaws additionally axially movable or the jaws are only radially movable and the ring axially displaceable.
  • the ring can be made in one or more parts.
  • an actuating element which is for example designed as an annular collar which engages one of the end faces of the pressing jaws or the outer ring.
  • the annular collar is arranged on the carriage or vice versa.
  • On the inside of the Schaftmatrize also several bead-shaped sections can be arranged, the number of which is greater than the number of existing pressing jaws.
  • the extrusion tool can be equipped with ejectors, wherein at least one ejector as a forming die for forming an inner contour, e.g. as a hexagon socket of the screw head is formed.
  • the movement of the ejector is controlled by a separate drive.
  • the multi-stage press may also contain other pressing or upsetting tools and a shearing device for cutting the supplied wire.
  • the wire 7 supplied as starting material is cut to a predetermined length by means of the shearing blade 1 and the cut wire section 8 is inserted into the mold cavity of the shank die 2b of the first extrusion tool 2 by means of a gripper or transport device not shown in detail.
  • the mold cavity of the shank die 2b is limited in its depth by a first ejector 9 fitted in the shank die 2b.
  • a second ejector 10 is likewise arranged opposite 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 ejector 9 and 10 After completion of the process stage II and the movement of the carriage 5 in its starting position of the preformed screw blank 8a is moved by means of the ejector 9 and 10 to a gripper or transport device.
  • the actuation of the ejector 9 and 10 by means of a separate drive unit, regardless of the movement of the carriage 5.
  • the screw blank 8a is then inserted by means of the gripper or transport device in the mold cavity of the Schaftmatrize 3b of the second extrusion die 3.
