  Verfahren zur Herstellung schmiedeeiserner Herdiochplatten und Einsatzringe. 



   Schmiedeeiserne Herdlochplatten   svurden   bisher in der Weise   hergestellt, dass   die Löcher aus den Platten ausgestanzt und um diese Vertiefungen vorgesehen wurden, in welche die Einsatzringe gelegt werden. 



   Bei diesem Herstellungsverfahren kann das beim Lochen der Herdplatte ausgestanzte Material 
 EMI1.1 
 zu bekommen, im Durchmesser   grösser   sein muss als das ausgestanzte Loch. 



   Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren, bei dem durch Einpressen eines Falzes um die Lochöffnung der ausgestanzten Herdplatte der Durchmesser der Öffnung verkleinert und hiedurch gleichzeitig eine Auflage und Zentrierung für den   Einsaüring   geschaffen wird. Die ausgestanzten Scheiben werden wieder gelocht, am äusseren und inneren Umfang in ähnlicher Weise gepresst, wodurch der äussere Umfang vergrössert und der innere verkleinert wird. Dieser Vorgang wird bis zum kleinsten vollen Ring fortgesetzt. 



   In der Zeichnung veranschaulichen die   Fig. 1 und II   in Querschnitt und Draufsicht Herdlochplatten und Einsatzringe, die nach dem neuen Verfahren hergestellt sind ; a ist die gelochte 
 EMI1.2 
 das Loch verkleinert und eine Auflage für den Einsatzring geschaffen. b ist die ausgestanzte Scheibe, b1 dieselbe gelocht und mit   eingepresstem   Falz am Umfang ; durch das Einpressen wird der äussere   Durchmesser vergrössert.   Bei b2 ist der Falz ähnlich wir bei a1 am Lochumfang hergestellt ; c stellt die aus b1 ausgestanzte Scheibe dar usw. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the production of wrought iron stove tops and insert rings.



   Wrought iron stove top plates have so far been manufactured in such a way that the holes were punched out of the plates and provided around these recesses in which the insert rings are placed.



   In this manufacturing process, the material punched out when the stove top is punched
 EMI1.1
 must be larger in diameter than the punched hole.



   The subject of the present invention is a method in which the diameter of the opening is reduced by pressing in a fold around the hole opening of the punched-out hotplate, thereby simultaneously providing support and centering for the intake ring. The punched-out disks are punched again and pressed in a similar way on the outer and inner circumference, whereby the outer circumference is enlarged and the inner one is reduced. This process continues down to the smallest full ring.



   In the drawing, FIGS. 1 and II illustrate, in cross-section and plan view, hearth plates and insert rings which are produced according to the new method; a is the perforated one
 EMI1.2
 the hole made smaller and a support for the insert ring created. b is the punched-out disc, b1 the same perforated and with a pressed-in fold on the circumference; Pressing in increases the outer diameter. At b2 the fold is made on the perimeter of the hole similar to that at a1; c represents the disc punched out of b1, etc.
