Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
- Die vorliegende Erfindung bildet ein Verfahren zur Herstellung von Rohransätzen an Metall-, vorzugsweise Stahl- und Messingröhren, welches gegenüber den bisher gebräuchlichen Methoden, nach denen diese Ansätze durch Ziehen und Strecken hervorgebracht werden, neben dem Vorzuge grofser Einfachheit und Billigkeit besonders den Vortheil besitzt, dafs das Material durch die Behandlung keinerlei Benachtheiligung, wie Schwächung, Verdrehung oder dergl., erfährt.- The present invention forms a method for the manufacture of pipe sockets Metal, preferably steel and brass tubes, which compared to the previously used Methods by which these approaches are brought about by pulling and stretching, besides the advantage of great simplicity and cheapness, it has the particular advantage that it does the material does not suffer any disadvantage from the treatment, such as weakening or twisting or the like., learns.
Die Erzeugung der Ansätze geschieht nämlich, wie in beiliegender Zeichnung schematisch dargestellt ist, mit Hülfe von Sand oder einem sonst hierzu geeigneten Material, am zweckmäfsigsten Silbersand, mit dem die Hauptröhre α je nach Zahl und Gröfse der herzustellenden Zweigröhren auf eine gewisse Höhe angefüllt, alsdann glühend gemacht und in eine ein- oder mebrtheilige Form b gebracht wird. Hierauf wird auf den in der Röhre befindlichen Sand c mittelst eines oder mehrerer durch die Rohrmündungen gehender Stempel d einer Presse von verschiedenen Seiten ein starker Druck ausgeübt, wodurch an der Stelle der Rohrwandung, welche von der Formmasse nicht bedeckt wird, zuerst ein starker Wulst f entsteht (Fig. 1), in dessen Aufsenwand ein Loch gebohrt wird, das sich bei wiederholtem Druck zur Mündung der entstehenden Zweigröhre g erweitert.This is because, as is shown schematically in the accompanying drawing, the approaches are produced with the aid of sand or some other suitable material, most expediently silver sand, with which the main tube α is then filled to a certain height, depending on the number and size of the branch tubes to be produced is made red-hot and brought into a unified or shared form b . Then, on the sand c located in the tube, one or more punches d of a press going through the tube mouths are exerted from different sides, whereby at the point of the tube wall, which is not covered by the molding compound, first a strong bead f arises (Fig. 1), in the outer wall of which a hole is drilled which, with repeated pressure, expands to the mouth of the resulting branch tube g .
Hierbei werden die Seitenwandungen des Wulstes_/ gegen die Form geprefst und bilden somit den gewünschten Rohrstutzen g (Fig. 2), während das übrige Material durch den Sand, der an demselben anhaftet, mit aus der Form gedrückt wird.Here, the side walls of the bead are pressed against the mold and thus form the desired pipe socket g (Fig. 2), while the remaining material is pressed out of the mold by the sand that adheres to it.
Je nach der Beschaffenheit der Form und der Menge des in der Hauptröhre zusammengeprefsten Sandes ist es möglich, mehrere verschiedenartig gelagerte und gebildete Ansätze zu erzeugen.Depending on the nature of the shape and the amount of what is compressed in the main tube Sand it is possible to produce several differently stored and formed approaches.
