Abstract

The core comprises a packet of U-shaped punchings (1) and a packet having a wedge shape (2). The taper of the wedge is chosen such that when the two packets are pushed together a self holding taper fit results. A tubular dowel (4) may be inserted into each flank of the taper fit as an additional safety measure to prevent the packets from moving apart. Typically these dowels are hardened steel tubes with an axial split which exert a spring pressure against the laminations. Additional holes (3) are provided for clamping bolts or rivets to hold the packets together. Clamping elements may also pass through the hollow dowels.

Description

Kern eines-Spielzeugtransformators Die Erfindung betrifft einen Kern eines Spielzeugtransformators bestehend aus einem Stapel von blechernen Ringen, yon denen jeder aus einem U-Blech und aus einem ebenfalls zweischenkligen-Keilblech zusammengefügt und mit Löchern zum Lagensichern mittels Bolzen versehen ist, welche das Verrutschen der Bleche verhindern und die Bleche werbinden. Toy Transformer Core The invention relates to a core a toy transformer consisting of a stack of tin rings, each of which consists of a U-shaped sheet metal and a two-legged wedge sheet metal is assembled and provided with holes for securing the position by means of bolts, which Prevent the trays from slipping and advertise the trays.

Gekennzeichnet ist die Erfindung dadurch, daß das U-Blech und das Reibblech paketweise mit Selbsthemmung ineinanderhaften, gegebenenfalls in weiterer Ausgestaltung der Erfindung in der Art, daß der Kraftschlüssigkeit der Selbsthemmung einmal längsdurchschlitzte Paßstifte zugeordnet sind.The invention is characterized in that the U-plate and the Stick the friction plate into one another in packets with self-locking, possibly in another Embodiment of the invention in such a way that the frictional connection of the self-locking once longitudinally slotted dowel pins are assigned.

Es wäre im Prinzip denkbar, jedes Keilgesteck mit Hilfe von Rasten bzwO Zähnen zu einem haftenden Keil - Porm schluß zu verbreitern, doch wurde erkannt, daß Stanzwerkx) zeuge für solche Verzahnungskonstruktionen wesentlich teurer sind als die ohnehin # sehr teueren-Stanzwerkzeuge, die nach der Erfindung geradlinige Keilpaßflächen aufweisen können und deshalb einen außergewöhnlich großen Produktionsfortschritt zeitigen. In principle, it would be conceivable to widen each wedge arrangement with the help of notches or teeth to form an adhesive wedge-shape, but it has been recognized that punching tools for such toothing constructions are significantly more expensive than the already very expensive punching tools that are used according to the Invention can have straight wedge-fitting surfaces and therefore bring about an exceptionally large production progress.

Die Zeichnung zeigt ein Ausführungsbeispiel mittels eines Grundrisses. Das Blech 1 und das Keilblech 2 haften paketweise mit Selbsthemmung ineinander0 Die Kraftschlüssigkeit dieser Selbsthemmung ist durch längsdurchschlitze Paßstifte 4 verstärkt, Die Löcher 3 dienen zum Durchstecken von Schrauben, mit welchen die Blechstapel zusammengepreßt werden0The drawing shows an exemplary embodiment by means of a floor plan. The sheet 1 and the wedge sheet 2 adhere to one another in packets with self-locking The force fit of this self-locking is achieved by means of longitudinal slots in alignment pins 4 reinforced, the holes 3 are used to insert screws with which the Sheet metal stacks are pressed together0
