Definitions

  • the invention relates to a method for the mechanical production of a segment brush and auxiliary means for carrying out the method, such as a transfer device and a press, as well as the segment brush itself.
  • Annular brushes are known and proven in various embodiments.
  • ring brushes of large axial length are often formed by combined segment brushes, which are axially clamped, for example, on a hollow cylinder serving for storage.
  • Such hollow brushes have a retaining ring around which a bristle trim is folded, wherein a radially inwardly lying, in a cross section approximately U-shaped, circumferential rivet holds the bristle facing against the retaining ring.
  • segment brush becomes less expensive due to the lower use of materials, and such segment brushes without a rivet can be put together to form substantially denser ring brushes, since a spacing of the segment brushes by the rivet is lacking.
  • a method for the production of a segment brush in which in a first process step, the production of a semi-finished product in the form of a bent 90 degrees bristle stocking by a taken in a sleeve and this sleeve axially projecting bristle bundles through a in the axial projection of the bristle bundle retracting conical mandrel of a press by 90 degrees is bent over a lying on the sleeve edge ring by 90 degrees.
  • the ring with 90 degrees angled bristle trim is removed from the press and mounted on a non-locking mandrel of another press, wherein the mandrel is radially spaced from a press table, whereby an annular shoulder surrounding the mandrel is formed. If there is an angling of the bristle facing on this annular shoulder, the bending of the second bending of the bristle facing towards the mandrel is effected by closing the press.
  • two further metal rings are pressed into the bristle border, so that a possibly U-shaped profiled, inner retaining ring is formed, which surrounds the around the ring folded bristle facing axially and radially from the inside.
  • the object of the invention is to provide a method for the machine production of a segment brush without a rivet and aids for carrying out this method.
  • the preparation of a bent by 90 ° and annularly arranged bristle trim with retaining ring is carried out in a conventional manner in a known machine.
  • the transfer device is introduced with mandrel forward until the first bend rests on the annular shoulder.
  • the inner diameter of the Retaining ring and the outer diameter of the mandrel can then be passed with this transfer device, the bristle trim with retaining ring, sufficiently stable sitting on the transfer device, for example, another existing press for pressing.
  • the attachment of the Abpressdorns at least partially immersed in an end-side recess in the central mandrel, which preferably rests over the entire end face of the mandrel of the Abpressdorn.
  • the central mandrel is moved after pressing by means of a device in its the annular shoulder of the ring projecting starting position. If the pressing takes place against the force of a spring, then this spring will spend the withdrawal of the Abpressdorns the central mandrel of the transfer device back to the starting position.
  • An alternative is a cylinder with piston.
  • a segment brush according to the invention is intended primarily to a bristle trim of a metal that can be permanently compressed.
  • synthetic materials in particular plastics, when a suitably heated bristle lining is pressed, in which case adhesion of the bristles to one another and also to bonding with, for example, a retaining ring made of a plastic may be intended.
  • the production of the semi-finished product is carried out in a first machine and the pressing in a remote from the first machine second machine. It is then in the second machine preferably also done the completion of a brush, for example, a trimming, a mistake with brush fittings or the like.
  • the implementation of the semi-finished product can be done automatically, for example by means of grippers, turret assemblies, cups or rods carrying chains or the like.
  • the transfer device for converting a semi-finished product of a segment brush can be designed in many forms. Basically, it is envisaged that a two Ring shoulders forming ring is provided that in the ring, a central mandrel is inserted to a stop a thorn-fixed annular shoulder to the lower annular shoulder of the ring for a system of bends of a bent 90 ° bristle trim of the segment brush on the upper annular shoulder of the ring and on the Mandrel, which is held by a retaining ring axially against the upper annular shoulder of the ring and radially against the mandrel for a reaction of the angled bristle trim.
  • the added, bent by 90 ° bristle facing opposite side of the transfer device according to the invention is adaptable to existing equipment such as presses, their shots, etc. largely freely designable.
  • the central mandrel is arranged completely displaceable in the ring.
  • the mandrel has a recess in the bristle-facing end face, the cross-section of which corresponds axially at least in sections to that of an attachment of a pressing mandrel of a press.
  • a form-fitting transition from the central mandrel on the essay or the Abpressdorn is thought so that the force of the press acts over the entire cross-sectional area of the Abpressdorns.
  • the second end side of the mandrel may have a cylindrical recess, so that the transfer device according to the invention can be placed on a pin, a pipe or the like, for example for a transfer from a first to a second production machine.
  • the ring sleeve-like design has an adapter for insertion into a receptacle of a press. Adapter and recording are then optimally matched to each other.
  • a device for moving the mandrel displaced during the pressing back into its starting position is provided, for example a compression spring or a cylinder with a piston.
  • plastic bristles are to be processed according to the invention, it may be expedient to provide a heater which can be configured both as a mandrel-proof and as ring-proof. Conveniently, such a heater will be operated electrically.
  • a receptacle is sleeve-like for the introduction of the mandrel of the transfer device, as explained above, that a free axial length in the sleeve for axial displacement of the mandrel during the pressing is sufficiently dimensioned and that a frontal Edge of the receptacle is designed as an abutment for the ring.
  • a receptacle provided, it is more appropriate to provide this instead of the transfer device with a device for moving the displaced during the pressing mandrel back to its original position, such a device may be a compression spring or a cylinder with pistons. Likewise, then this recording will have a heater for pressing plastic bristles.
  • the in the FIGS. 1 to 3 shown transfer device 1 is structurally simple.
  • the transfer device 1 has a ring 2 through which, perpendicular to the axial extent of the ring 2, two annular shoulders 3,4 are formed frontally.
  • a central mandrel 5 is axially displaceable, but towards a bent by 90 ° bristle trim 6 only up to the in FIG. 2 shown stop a pin fixed annular shoulder 7 at the lower annular shoulder 4 of the ring. 2
  • the second bend 9 of the bristle trim 6 extends annularly and fitting around the central mandrel 5 and projects axially therefrom.
  • a retaining ring 10 holds the first bend 8 axially against the annular shoulder 3 of the ring 2 and the second bend radially against the mandrel. 5
  • the production of the retaining ring 10 by 90 ° angled bristle trim 6 can be done in a conventional manner in a machine. It is then the transfer device 1 introduced into the machine, for example, with a recess 11 in the bristle facing 6 facing away from end 12 seated on a reciprocating piston.
  • FIG. 4 shows the arrangement of a Abpressdorns 13 via a transfer device 14 with ring 15 and central mandrel 16th
  • this arrangement has a sleeve-like receptacle 17, in which the mandrel 16 is inserted so far until the ring 15 rests with its lower annular shoulder 18 over its entire surface on the front edge 19 of the receptacle 17.
  • the axial displacement of the sleeve 17 is dimensioned such that the central mandrel 16 can be moved completely below the upper annular shoulder 20 of the ring 15 against the force of a spring 21.
  • a pointed conical attachment 22 of the pressing mandrel 13 will spread apart the bristle stock protruding axially from the mandrel 16 and thus predetermine the radial direction for pressing.
  • This cone-shaped attachment 22 will then impinge on the central mandrel 16 and be received therein in a front-side recess 23, so that the Abpressdorn 13 and the central mandrel 16 are positively connected.
  • the central mandrel 16 With progressing pressing operation, the central mandrel 16 is displaced in the sleeve-like receptacle 17 against the force of the spring 21 and pressing the bristle around a retaining ring between an annular shoulder 24 of the Abpressdorns 13 and the upper annular shoulder 20 of the ring 15, wherein the outer diameter of Ring shoulder 24 which corresponds to the annular shoulder 20.
  • the transfer device has a sleeve-like ring, as shown in FIG. 4 formed by the ring 15 and the receptacle 17, and has an adapter, for example in the form of a pin 25 for insertion into a press-side receptacle.
