Abstract
Description
Die Erfindung betrifft einen Speiser aus einer insbesondere exothermen Heizmasse für ein metallisches Gußstück in der Form einer Glocke mit einem eingezogenen Glockenrand.The invention relates in particular to a feeder exothermic heating compound for a metallic casting in the Bell shape with a recessed bell rim.
Ein derartiger Speiser ist aus DE 195 03 456 C bekannt. Jener Speiser ist einstückig aus gleichem Material hergestellt. Der eingezogene Glockenrand dient dazu, ein leichtes und sicheres Abbrechen eines mit Gußmasse gefüllten Speisers von dem zuge hörigen fertigen Gußteil zu gewährleisten. Ein eingezogener Glockenrand erschwert die Herstellung eines einteiligen Spei sers.Such a feeder is known from DE 195 03 456 C. That one Speiser is made in one piece from the same material. Of the retracted bell rim serves to be a light and safe Breaking a feeder filled with casting compound from the supplied to ensure proper finished casting. A fed Bell rim complicates the production of a one-piece spit sers.
Hiervon ausgehend beschäftigt sich die Erfindung mit dem Pro blem, einen Speiser mit eingezogenem Glockenrand rationeller als bisher herzustellen. Der eingezogene Glockenrand wird in der Fachsprache als Brechkern bezeichnet und seine Wirkung hängt ganz wesentlich von der ihm gegebenen Form ab. Daher ist es ein weiteres Ziel der Erfindung, dem als Brechkern dienenden Glockenrand des Speisers eine entsprechend "brech wirksame" Form und Ausgestaltung zu geben. Proceeding from this, the invention deals with the pro blem, a feeder with retracted bell rim more rational than before. The indented bell rim is in the technical term referred to as crushing core and its effect depends very much on the form given to it. Therefore it is another object of the invention, that of a crushing core serving bell edge of the feeder a correspondingly "breaking effective "form and design.
Zur Lösung dieses Problems wird erfindungsgemäß ein den Gloc kenrand bildendes flaches auf den Speiser-Grundkörper aufzu setzendes Ringteil vorgeschlagen.To solve this problem, a Gloc flat edge forming on the base of the feeder setting ring part proposed.
Dieses Ringteil kann ein einfacher Blechring sein. Eine be sonders vorteilhafte Eigenschaft eines Blechringes besteht in der plastischen Verformbarkeit des Bleches, wodurch ein Teil der Aufprallenergie beim Aufformen des Speisers absorbiert werden kann. Anstelle eines Blechringes kann somit auch ein Ring jedes anderen möglichst plastisch verformbaren Materials eingesetzt werden, sofern dieses Material nur keine elastisch rückfedernde Eigenschaft besitzt. Eine federnde Eigenschaft würde nach dem Aufformen des Speisers die unter dem Speiser befindliche Sandschicht beschädigen oder zerstören.This ring part can be a simple sheet metal ring. A be A particularly advantageous property of a sheet metal ring consists in the plastic deformability of the sheet, making a part the impact energy absorbed when molding the feeder can be. Instead of a sheet metal ring, a can also be used Ring of any other plastically deformable material are used, provided that this material is only not elastic has resilient properties. A resilient quality would after the molding of the feeder that under the feeder damage or destroy the sand layer.
Ein wichtiger Vorteil eines Blechringes besteht unter anderem darin, daß durch seine kraftabsorptive Eigenschaft die Sand schicht unter dem Speiser besonders dünn gehalten werden kann. Dadurch ergibt sich ein verminderter speisungstechni scher Abschirmeffekt im Speiserhals, was zu einer verbesser ten Speiserwirksamkeit führt.An important advantage of a sheet metal ring is, among other things in that the sand layer under the feeder can be kept particularly thin can. This results in a reduced feed technology shielding effect in the esophagus, which leads to an improvement food efficiency.
Das erfindungsgemäße Ringteil kann in beliebiger Weise mit dem Grundkörper des Speisers verbunden sein. Eine recht ein fache Verbindungsart besteht darin, das Ringteil aufzukleben, aufzuklemmen oder auch aufzutackern. The ring part according to the invention can be used in any way be connected to the base body of the feeder. A pretty one simple connection is to glue the ring part, unclamp or staple.
Ein Speiser mit einem aufgesetzten Fußteil an dem offenen Glockenrand ist bereits aus DE 42 19 632 A bekannt. Das dor tige Fußteil ist jedoch ein relativ kompliziert ausgebildetes Formteil, das mit dem erfindungsgemäß vorgeschlagenen flachen Ringteil zumindest aus dem Gesichtspunkt einer rationellen Fertigung nicht vergleichbar ist.A feeder with a foot part attached to the open one Bell rim is already known from DE 42 19 632 A. The dor term foot part is, however, a relatively complicated one Molding that with the proposed according to the invention flat Ring part at least from the point of view of a rational Manufacturing is not comparable.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt, die einen Schnitt durch einen Speiser zeigt.An embodiment is shown in the drawing shows a section through a feeder.
Der glockenförmige Grundkörper 1 des Speisers besteht aus exothermem Material. An dem offenen Glockenrand ist ein radi al in die Glockenöffnung ragender Blechring 2 als Brechkern aufgeklebt.The bell-shaped base body 1 of the feeder consists of exothermic material. On the open edge of the bell, a sheet metal ring 2 projecting radially into the bell opening is glued on as a breaking core.
Wie ein derartiger Speiser bei einer Gußteilherstellung ein gesetzt wird, ist in der eingangs zitierten DE 195 03 456 C ausführlich beschrieben.How such a feeder in a casting production is set is in DE 195 03 456 C cited at the beginning described in detail.
