Description

Ätzgrund für das Ätzgravieren von Schmiedegesienken Die Erfindung bezieht siech auf einen Ätzgrund für das Ätzgravi@e:ren. von Schmiedegese ulken.Etching base for the etching of forged dies The invention refers to an etching base for the Ätzgravi @ e: ren. von Schmiedegese ulken.

Die: Hersteliliunig von Gesenken für Gesenkschml:iedeistücke hoher Geniauigkeit isst zeitraübenid, teuer und nur durch hio@chqiuia;lifizieirte Facharbeiter ausführbar. Die Erfindung geht zwecks Beseitigung dieses Übelstandes von dem zur Werkzeughersitel.lung bereits be: kannten Ä,tzgravierverfahren aws, durch dass nach einem dem zu schmiedenden Teil genau entsprechenden Ur- odier Positivmodelil auf einfache Weise belie:b:ig viele gleiche Werkzeuge von höchster Genauigkeit hergestellt werden können.Die: Manufacture of dies for die castings: much higher Genius eats time-wasting, expensive and only through hio @ chqiuia; certified skilled workers executable. The invention is for the purpose of eliminating this drawback of the for Werkzeughersitel.lung already known Ä, etching process aws, by that after an original or positive model that corresponds exactly to the part to be forged in a simple way, any number of the same tools are manufactured with the highest precision can be.

Bei diesiem Ätzgravievverifahren wird, die Arbeitsfläche dies Rohwerkzeuges mit einem als Ätzgrund bezei.chnieten Abdeckmittel Überzogen, welches bisher üblicherweiise aufs einer fettigen Paste von Butterkonsistenz bestand. Auf das so vorbereitete Rohwerkzeug wird das Urmodell aufgesetzt und. leicht angedrückt, so daß der Ätzgrund an dien. zum Tragen kommenden; Stellen des Rohwerkzeuges verdrängt wird und am Urmodell beim Abheben vorm Roh w-eirilszeug ha.ftenb(leibt. Dais Rohwerkze!ug wird dann. dem Angriff einer Säure ausgeisetzt, welche diais Überschüssige Metall an den bdaniken Stellen weigätzt. Dieser Vorgang wird so, oft wiederholt, bis die ges-amteArbeitsfläc:he Beis Rohwerkzeuges beim Andrücken des Urmodells gleichmäßig trägt und infolgedesisein ein genaues, negatives Abbilid des positiven Ur@mioideillis darstellt.With this etching engraving process, the work surface of this raw tool Coated with a covering material, which was previously used as an etching base, riveted insisted on a greasy paste of the consistency of butter. For what has been prepared in this way The master model is placed on the rough tool and. lightly pressed so that the etching base to serve. coming to fruition; Place the raw tool is displaced and on the master model when lifting in front of the raw w-eirilszeug ha.ftenb (leibt. Dais raw tool! ug then becomes. exposed to the attack of an acid, which diais excess metal on the surfaces Places white-etched. This process is repeated so often until the entire working area In the case of the rough tool, when the master model is pressed on, it carries uniformly and consequently thesis represents an accurate, negative image of the positive Ur @ mioideillis.

Ein Nachteil dieses Verfahrens ist darin zu da.ß der geib,räuch!licheÄtzgrund. infolge, seiner weichen, schmierenden Konsistenz keineswegs immer, wie dies, gewünscht wird, an den betreffenden Stell, en nur am Urmodeill haftenibleiibt und mit .demselben abgehoben, werden kann., sondern daß er leicht wenigstens teilweise am Rohwerkzeug klcbenibleibt und durch mühsameHandarbieit entfernt werden miuß, wobe=i leicht auich, benachbarte, abzudeckende .Stellen freigelegt werden können.. Ferner ist es umständlich, das Urm-oidie:lil nach jeidiesimaligem Abheben, vom Roh-,.verl:ze,ug von deir anhaftenden, fettigen Masse reinigen zu müssen. Die. Sühnefligikeit und Genauigkeit deis Verfahrens leiden darunter entsprechend.One disadvantage of this process is that the yellow, smoky etching ground is used. as a result of its soft, smeary consistency, by no means always desired like this will, at the relevant points, only remain liable to the original fashion and with the same lifted, can be., but that he can easily at least partially on the raw tool Klcbenbeem and must be removed by laborious manual work, where = i easily, Adjacent locations to be covered can be exposed .. Furthermore, it is awkward to the Urm-oidie: lil after each lifting off, from the raw,. having to clean greasy mass. The. Atonement and accuracy of the procedure suffer accordingly.

Beim Tiefätzen von Schneidsteimpeln isst es bereits bekannt, die Stempelzeichnung in Umrißlinien auf die Oberfläche de!s Stempels mit säurefestem Lack aufzutraigen. und die Oberfläche dann so Fange tief zu, ätzen, bis dieUmrißilinien die eirfoirder"liicheHöhe und Schärfe besitzen. @Die Erfindung besteht in der Anwendung von als Abideclcimittiel bei diesem Tiefätizen vom. Schneidstempeln bekanntem, säurefestem Lack als heim Ätzgravieren von Schmiieidegesenken durch den. Druck einer Fertigfürm des zu schmiedenden Werkstückes auf die, von. der- Fertigform noch abweichenden Stellen des Robgesenkes zerstörbarer Ätzgrund.When deep-etching cutting sticks, it is already known to eat the stamp drawing to be drawn in outlines on the surface of the stamp with acid-resistant varnish. and then etch the surface so deeply, until the outline lines correspond to the height of the surface and have sharpness. @The invention consists in the use of as Abideclcimittiel at this deep down from. Cutting stamps known, acid-proof varnish as home Etching of forging dies through the. Printing a ready-made form of the to be forged Workpiece to, from. the finished form still deviating points of the Robgesenkes destructible etching base.

Durch die Erfindung- wird erreicht, daß der säurefeste Lack an. dein von, der Feritiigform abweichenden, zum Tragen kommenden Stellen durch den Druck der Feritigifoirim zwrsplittert und dann mühelos, z. B. durch Wegbiesen, entfernt weirden kann. Der Arbeitsvoiriga;ug wird aiuf diese Weise wesentlich, einfacher, sauberer und rascher ausführbar. Auch werden die Konturen der blanken: Stellen des Arbei:tsgesenkes genauer. Dias Verfahren gemäß der Erfindung eignet sich besonderes zur Heriste:llung- von Teilen mit zur Hauptachse geneigten Bearbeitungsflächen., z. B. von Kegeilrädern, weil dein nach dein Auftragen erhärtete- Lack auch bei höherer Außentempüratur nicht, wie- der, bisheir übliche Mutterartige Ätzgrund, an den geneiigten Flächen zum Fließen kommen und daidurch diel Arbeit erschweren oder sogair veriderhen kann.By the invention it is achieved that the acid-resistant paint. your from, the ready form deviating, coming to bear by the pressure the feritigifoirim splintered and then effortlessly, e.g. B. by tucking away can weirden. In this way, the workload becomes much, simpler, cleaner and quicker to execute. Also the contours of the bare: places of the Work: tsgesenkes more precisely. The method according to the invention is particularly suitable for the creation of parts with machining surfaces inclined to the main axis., z. B. of bevel gears, because your paint hardened after your application, even at higher levels Outside temperature not, again, up to now usual mother-like etching ground, on the inclined Surfaces come to flow and thereby make the work difficult or even prevent it can.

Dem säurefesten Lack isst ein sonstiger, nach dein Auftragen erhärtender und untrer dem Druck der Fertigform zerstörbarer Stoff gleichwertig.The acid-resistant varnish eats another, which hardens after your application and substance that can be destroyed under the pressure of the finished form.
