Description
Herstellung von Flanschen Flansche werden gewöhnlich aus Werkstücken geschmiedet, die Prismen- oder Zylinderform besitzen. Vielfach stanzt man auch die Werkstücke als volle oder gelochte Scheiben aus Blechen aus und zieht oder preßt sie anschließend fertig. Ausnahmsweise, in der Hauptsache nur bei sehr großen Flanschen, wenden als Werkstücke unter Hämmern aufgedornte und vorgeschmiedete Ringe verwandt.Manufacture of flanges Flanges are usually made from workpieces forged, which are prismatic or cylindrical in shape. Often you also punch them Workpieces as full or perforated disks from sheet metal and pulls or presses then finished. Exceptionally, mainly only with very large flanges, use blown and pre-forged rings as workpieces under hammers.
Bei den bekannten Herstellungsarten hat man entweder viel Werkstoffabfall durch Außengrat oder Blechzwickel und Lochputzen, oder aber, nämlich im Falle der Verwendung handgeschmiedeter Ringe als Ausgangsform, hohe Lohnkosten. Das Verfahren der Erfindung vermeidet demgegenüber jeden Abfall; es ermöglicht schnelle .und billige Herstellung der Ringwerkstücke bei ausschließlicher Verwendung ungelernter Arbeiter. Es bietet weiter im Vergleich zu den bisherigen Schmiedearbeiten den Vorteil, daß sich die Flansche mit bedeutend geringeren Drücken herstellen lassen, da man ,dem R@ngwerksmück mit der Schmiedemaschine günstige- Querschnitte verleihen kann; man kommt also mit leichteren Hämmern oder Pressen aus.With the known manufacturing methods, one either has a lot of material waste by outer ridge or sheet metal gusset and hole plastering, or else, namely in the case of Use of hand-forged rings as the starting form, high labor costs. The procedure In contrast, the invention avoids any waste; it enables fast. and cheap Production of the ring workpieces with the exclusive use of unskilled workers. In comparison to previous forging work, it also offers the advantage that the flanges can be produced with significantly lower pressures, since one, the R @ ngwerksmück can give favorable cross-sections with the forging machine; man So it gets by with lighter hammers or presses.
Es werden zwar schon Flansche an der Stange durch Fertigstauchen und nachfolgendes Lochen ohne Abfall fertiggeschmiedet, jedoch nur in kleineren Abmessungen, da die vorhandenen Schmiedemaschinen zu klein und zu schwach sind. Das Verfahren der Erfindung läßtdagegen die Herstellung der größten handelsmäßigen Flansche zu.There are already flanges on the rod by pre-upsetting and subsequent punching forged without waste, but only in smaller dimensions, because the existing forging machines are too small and too weak. The procedure the invention, however, allows the production of the largest commercial flanges.
Die Erfindung besteht darin, daß als Ausgangswierkstück ein in bekannter Weise an der Stange geschmiedeter und von dieser abgetrennter Ring benutzt wird. In Abb. i bis 3 ist das Verfahren der Erfindung dargestellt, und zwar zeigen Abb. i und 2 das Vorstauchen und Lochen des Ringes, das auf der Schmiedemaschine vorgenommen wird, während in Abb.3 das Fertigschmieden unter dem Hammer oder der Presse zu sehen ist.The invention consists in that as an output swivel in a known Wise forged on the rod and separated from this ring is used. In Fig. I to 3 the method of the invention is shown, namely Fig. i and 2 the pre-upsetting and piercing of the ring, which is done on the forging machine while in Fig.3 the finish forging under the hammer or the press can be seen is.
