Description
Universalwalzwerk zum Auswalzen von Hohlkörpern. Die Erfindung betrifft ein Universalwalzwerk zum Auswalzen von Hohlkörpern und besteht im wesentlichen darin, daß die Walzen gallig oder doppelkegelförmig ausgestaltet sind. Die bisher zum Auswalzen von Hohlkörpern gebräuchlichen, mit zylindrischen glatten Walzen versebenen Universalwalzwerke weisen den Nachteil auf, daß zur Herstellung des Fertigproduktes eine große Anzahl von Stichen erforderlich ist, wodurch ganz erhebliche Anlage- und Betriebskosten bedingt werden. Man ist stets bestrebt gewesen, eine Herabminderung der Kaliberanzahl zu erzielen, doch sind alle diesbezüglichen Versuche bisher vergeblich gewesen. Es wurde nun gefunden, daß dem erwähnten Nachteil dadurch in Wirksamer Weise abgeholfen werden kann, daß man an Stelle der bisher gebräuchlichen zylindrischen glatten Walzen gallige oder doppelkegelförmig gestaltete Walzen verwendet. Diese Walzen bringen den großen Vorteil mit sich, daß sie bei jedem Stich möglichst weit bis zur gewünschten Wandstärke vordringen, so d-aß man mit weniger Kalibern als bisher auf den gleichen Querschnitt kommen kann. Es hat sich gezeigt, daß man unter Verwendung der neuen Walzen im Universalwalzwerk das Fertigprodukt bereits in drei und sogar in zwei Kalibern erzielen kann. Die Folge hiervon ist, daß man weniger Walzgerüste braucht, wodurch die Anlage- und Betriebskosten ganz erheblich herabgemindert werden. Beiliegende Zeichnung stellt zwei Ausführungsformen der Erfindung Beispielswiese dar, und zwar veranschaulicht Abb. i bis 3 die Verwendung galliger Walzen, Abb. q. und 5 die Verwendung doppelkegelförmiger Walzen.Universal rolling mill for rolling out hollow bodies. The invention relates to a universal rolling mill for rolling out hollow bodies and consists essentially in that the rollers are bilious or double-cone-shaped. The so far For rolling out hollow bodies, level with smooth cylindrical rollers Universal rolling mills have the disadvantage that for the production of the finished product a large number of stitches is required, resulting in very considerable investment and operating costs. One has always endeavored to downgrade the number of calibres, but all attempts in this regard have so far been in vain been. It has now been found that the aforementioned disadvantage is thereby made more effective This can be remedied by replacing the previously used cylindrical smooth rollers bilious or double-cone-shaped rollers are used. These Rollers have the great advantage that they go as far as possible with each stitch penetrate to the desired wall thickness, so you d-ate with fewer calibers than so far can come to the same cross-section. It has been shown that one under Using the new rolls in the universal rolling mill, the finished product is already in three and can even achieve in two calibers. The consequence of this is that you get less Roll stands needs, which significantly reduces the investment and operating costs will. The accompanying drawing depicts two embodiments of the invention by way of example Fig. i to 3 illustrate the use of bilious rollers, Fig. q. and 5 the use of double-cone rollers.
Wie aus Abb. i bis 3 ersichtlich, kann durch die Verwendung von je vier Balligen Walzen a1, b1, cl, dl oder a2, b2, c2, d2 oder a3, b3, c3, d3, welche auf den Hohlkörper w einwirken, bereits in drei Stichen das Endprodukt erzielt werden.As can be seen from Fig. I to 3, by using four crowned rollers a1, b1, cl, dl or a2, b2, c2, d2 or a3, b3, c3, d3, which act on the hollow body w , already the end product can be achieved in three stitches.
Wie aus Abb. q. und 5 ersichtlich, kann durch Verwendung von j e vier doppelkegelförmigen Walzen a1, b1, cl, dl und a2, b2, c2, d2, welche .auf den Hohlkörper w einwirken, bereits in zwei Stichen das Fertigprodukt erzielt werden, indem durch die abgeänderte Walzenform jedesmal eine stärkere Querschnittsabnahme erzielt wird.As shown in Fig. Q. and 5 can be seen by using each four double-conical rollers a1, b1, cl, dl and a2, b2, c2, d2, which .on the hollow body w act, the finished product can already be obtained in two stitches by through the modified roll shape each time a greater reduction in cross-section is achieved.
Anstatt den Dorn für das Walzgut festzulegen und die Walzen anzutreiben, kann man auch den Dorn antreiben und die Walzen als Schleppwalzen arbeiten lassen.Instead of fixing the mandrel for the rolling stock and driving the rolls, you can also drive the mandrel and let the rollers work as drag rollers.
