DE1911348A1 - Fixing a flange to a spool body - Google Patents

Abstract

The spool, as used for winding wire or thread on, consists of a core and a flange which are made in one piece. A flange manufactured from a plastic material by moulding, is connected to the other bobbin part in such a way that it is fixed solidly or can be removed again.

Description

V E R B I N D U N Q S - S Y S T E M The invention relates to a connection system, wisely applicable to bobbins, for example for insulated fine copper wires as well for the fibers or winding materials used in the textile and chemical industry made in particular from chemical materials (e.g. plastics of all kinds), consisting of, e.g.

body part manufactured in one casting (a flange with a core) as well as another separately manufactured part (.. flange). The separately manufactured Part (e.g. flange) is preferably with long-slot openings arranged in a circle equipped 5 the during assembly to accommodate appropriately designed pin lugs (Slats) z * B. at the flangeless end of the body part (e.g. flange with core) one pour, serve. On the separately produced loose teal (e.g. flange part) are also connected in one cast, also cone-noses (lamellae), which are, during assembly, with the peg lugs (lamellas) at the free (e.g. flangeless) end of the body part (e.g. flange with core) press into one another like a wedge and create a closed Form ring collar. At the same time, the loose part, which has been separated from the other, lies down (e.g. flange part) in continuation of the long slot openings molded support ring on the corresponding support surface at the free (e.g. flange-less) end of the body between the aforementioned made of pressed-together tenon noses (Lamellas) formed outer ring-collar -and the inner closed ringz, B.

Collar which is cast in one piece with the coil body.

On the aforementioned support surface at the (e.g. flangeless) end of the Body (e.g. bobbin) and on the ring collar are correspondingly congruent Poured holes, which lead to a possibly necessary mechanical fastening of the separately manufactured part e.g. flange part) with the other body part (e.g. flangeless bobbins), for example via rivets, self-tapping screws, Pins or other fasteners are used. It is also provided, for example, with the cone-noses (on e.g.

flangeless) end of the body part cross bores or

to attach other aged breakthroughs through which, after the separately manufactured loose part (e.g. flange plate) e.g.

is pressed onto the bobbin, wedge-like cross-latches over the loose part (e.g. flange part) and, if necessary, a safeguard against form the loosening of the part (e.g. flange part).

Finally, after assembly, the support cover is also used (e.g. on the flange) there are two protruding support rings that are stuck together Press into the space formed by the outer and inner ring collar and press flush on the support ring of the loose part (e.g. flange part), effective as a back lock for the mounted separate part (e.g. flange part).

All contact points or connection points of the assembly parts are like this laid out1 that this should preferably be dissolved in solvents (e.g. benzene (e.g. Benzene with material components) immersed or

respectively.

can be painted, whereby at the contact (connection points) the material components of the various assembly parts flow into one another and form a compact, almost one-piece structure.

In the design (development, construction) 1 for example of large coils with overlong cores and other similar structures, more suitable Individual elements, as well as their connection systems, must be based on the different structural Structure of the winding material1 different cross-sections and winding volumes and winding construction, as well as a wide range of chemical, thermal and mechanical Burdens, consideration must be taken. Also (for example with machine coils) on the running accuracy (especially vertical and lateral runout).

The proposed connection system (in building block form) comes to this Opposes requirements or includes them to a large extent and offers more than that In addition, a dimensionally stable, cost-saving, rational manufacturing option.

The invention has set itself the task of creating a versatility and adaptable modular connection system, especially for large coils, to create, which includes a large area of application in many Variants, a large area for almost all technical and spatial requirements offers new possibilities and thus represents progress.

With reference to the accompanying drawing, an embodiment of the Invention described and presented Fig. 1 e.g. 4 shows Fig. 1 a sectional side view of a coil (body part consisting of flange With core made of one piece with pressed (mounted) loose flange part and upper and lower support cover with the details according to the invention.

For example, Fig. 2 shows a top view of the coil from direction A (body part consisting of a flange with a core made of one cast) without a cover, Fig. 3 shows e.g. a Top view of the coil from direction B (without cover)
