Die Erfindung bezieht sich auf eine Vorrichtung zum Herstellen von Gitterkörben, die aus runden oder ähnlich gestalteten Blechplatten durch Pressen, Stanzen und Ziehen zu konischen Behältern umgeformt sind. Hierbei wird vor dem Stanzen die Platte mit einem tellerartigen Rand versehen und nach dem Stanzen der nicht mit Schlitzen versehene Bodenteil von dem oberen Rand weggezogenThe invention relates to a device for the production of mesh baskets, which are made from round or similarly shaped sheet metal plates by pressing, punching and drawing are formed into conical containers. Here, the plate is with before punching provided with a plate-like edge and after punching the one not provided with slots Bottom part pulled away from the top edge

Beim Anwenden dieses Herstellungsverfahrens hat sich jedoch gezeigt, daß das Schlitzen der Blechplatten durch Stanzmesser, besonders bei größeren Körben) wesentliche Schwierigkeiten, macht, da einerseits die Schnittlängen erheblich anwachsen und andererseits sich die ausgeschnittenen Ringe in den Matrizen so festsetzen, daß die Plätten nur unter An-When using this manufacturing process, however, it has been found that the slitting the sheet metal plates by punching knives, especially with larger baskets) substantial difficulties, makes, because on the one hand the cutting lengths increase considerably and on the other hand fix the cut-out rings in the dies in such a way that the plates can only be
ao wendung starker Gewult aus den Matrizen entfernt werden können. Hierbei brechen jedoch viele Gitterstäbe ab; so daß fast 2oProzent Bruch bei der Fabrikation zu verzeichnen ist. Gemäß der Erfindung wird nun diesem Ubelstand dadurch abgeholfen, daß zum Ausstanzen ein als umlaufendes Futter ausgebildeter Gegenhalter mit stufenartigen Furchen Verwendung findet, dessen als Schneiden wirkende Kanten Unterbrechungen tragen, und daß eine Scheibe achsial zum Gegenhalter zur Bearbeitung angedrückt wird.ao application of strong waves from the matrices can be removed. Here, however, many bars break off; so that almost 2o percent Breakage is recorded during manufacture. According to the invention, this is now a disadvantage helped by the fact that a counter-holder designed as a circumferential chuck with step-like furrows is used for punching out, the latter acting as cutting edges Edges wear interruptions, and that a disc axially to the counter holder for processing is pressed.
Auf der Zeichnung sind die Hauptbestandteile der neuen Vorrichtung in den Fig. 1 bis 4 dargestellt, während Fig. 5 das fertige Werkstück veranschaulicht. ,The drawing shows the main components of the new device in FIGS. 1 to 4 while Fig. 5 illustrates the finished workpiece. ,
Ein mit stufenartigen Furchen α ausgebildetes umlaufendes Futter b, z.B. ein abgestumpfter Kegel, wird in den sich drehenden Teil c einer Drehbank gespannt und darüber die tellerartige vorgepreßte Blechplatte d aufgedrückt, welche durch eine Mutter e am Teil c befestigt \vird. In den Support der Drehbank wird nun die Schneidscheibe f eingespannt, welche achsial von Stufe zu Stufe gegen die Blechplatte d gedrückt wird und so die Schlitze hervorruft. In den Schnittkanten der Stufen a sind Unterbrechungen h angeordnet, so daß das Blech d die in Fig. 4 dargestellte Ausbildung erhält.A circumferential chuck b formed with step-like furrows α , e.g. a truncated cone, is clamped in the rotating part c of a lathe and over it the plate-like pre-pressed sheet metal plate d is pressed, which is fastened to part c by a nut e. The cutting disk f is now clamped into the support of the lathe, which is pressed axially from step to step against the sheet metal plate d , thus creating the slots. Interruptions h are arranged in the cut edges of the steps a , so that the sheet metal d is given the configuration shown in FIG.
Um ovale Gitterkörbe vorschneiden zu könneil, müssen die Gegenhalter b dementsprechend gestaltet auf einer Ovaldrehbank befestigt werden. Zur Vereinfachung des Transportes der Schneidscheibe f können die Abstufungen auf dem Gegenhalter aus einer Schraubenlinie gebildet werden.In order to be able to pre-cut oval mesh baskets, the counter holder b must be designed accordingly and attached to an oval lathe. To simplify the transport of the cutting disk f , the gradations on the counter holder can be formed from a helical line.
Zur Erreichung des Werkstückes nach Fig. 5 wird der nicht mit Schlitzen versehene Bodenteil von dem1 Rande weggezogen oder weggedrückt, 'wodurch die mit der den Erfindungsgegenstand bildenden Vorrichtung entstandenen Schlitze zu Maschen gezogen werden.To achieve the workpiece according to Fig. 5 the non-slotted base part is pulled away or pushed away from the edge 1 'are drawn whereby the forming the subject of the invention apparatus slots formed into stitches.
