Description

existing double cone are displaceable, the double cone is rotatably but slidably mounted on a support tube and the sliding elements articulated to this hinged push rods, which are parallel to the axis of rotation of the winding mandrel in a likewise fixedly arranged on the support tube push rod guide by a known adjusting mechanism, are drivable.

In a further embodiment of the invention, it is provided for generating the necessary clearance for withdrawing the winding products, that in the support tube an actuating rod is arranged, at one end of a guided in slots of the support tube web is fixed, which in turn with the pioneering of the push rod guide end of Double cone is firmly connected.

embodiment

The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawing shows the

Front view of the device, partially shown in section. ·

As shown in the drawing, the device has a double-cone 2 arranged on a support tube 1 in a rotationally fixed manner, wherein the two cones 3, 4 are of identical design and inclined in the same direction. Each cone 3,4 is provided on the surface inclined to the longitudinal axis with a plurality of circumferentially distributed sliding guide 5, wherein in the respective in the same plane in the cone 3 and 4 arranged sliding guides 5 sliding elements 6 are displaceable.

The mutually associated sliding elements 6 are connected by a mounted on the respective sliding element 6 winding segment carrier 7, whereby upon displacement of the sliding elements 6 in the sliding guides 5, the distance of the winding segment carrier 7 to the longitudinal axis and thus to the axis of rotation of the double cone can be changed.

The displacement of the sliding elements 6 is made possible by push rods 8, which transmit a force of an external adjustment possibility to the sliding elements 6. For this purpose, the push rods 8 in a likewise non-rotatably mounted on the support tube 1 push rod guide 9 in which they (not shown in detail) are displaceable by the outer adjustment, guided, wherein the other end of the divided by a joint push rod 8 at the associated

Sliding element 6 is articulated. ,

If the push rods 8 are moved in the direction of the double cone, the sliding elements 6 slide on the sliding guides 5 of the double cone 2 and lift the winding segment carriers 7, which at the same time represent the mechanical coupling of the sliding elements 6 on both cones 3, 4 to a larger radius. The setting of the winding segment carrier 7 is thus directly dependent on the positioning of the push rods 8, i. at the same position of the push rods 8 you get the same high set winding segment carrier 7, the z. B. allow circular or square coil cross-sections. In an arrangement of z. B. four winding segment carriers 7 can be rectangular or oval coil cross-sections realize in which the diagonally arranged push rods * 8 are positioned in pairs equal and against each other differently. The push rods can also be set independently and thus any coil cross sections can be realized.

It is also possible, for. B. especially with symmetrical coil cross-sections, the push rods firmly, according to the desired dimensions, set and necessary for the removal of the winding product space by moving the double cone 2 by means of z. B. an associated Stellstahge TO, which protrudes through the support tube 1 and fixed to one end of the control rod 10 fixed web 11, which is guided in corresponding slots 12 in the support tube 1, fixedly connected to the outwardly facing end face of the cone 3 is to produce.

The frictional engagement between the carrier tube 1 and double cone 2 is ensured by a wedge 13, which slides in a guide groove 14 in the support tube 1.

The scope of the winding device can be divided by any division into winding segments, so that z. B. three offset by 120 ° sliding guides 5 or unevenly distributed sliding guides 5, etc. are provided.

The winding device is characterized by a simple structure with simultaneously large variability of the coil cross-sectional shape.

For this 1 page drawing Field of application of the invention The invention can be advantageously used in transformer construction in the production of round coil forms of strip or wire material and those with deviating from the circular shape cross-sections. Characteristic of the known state of the art According to DE-AS 2211685 (H 01 F, 41/04), an adjustable winding core for winding devices for the production of coils for large electric machines, such as transformers and chokes, is already known, wherein the jacket of the winding core of rail-shaped, by a common adjusting radially slidable components is formed. It is provided that the rail-shaped components consist of two nested, mutually leading sheet metal profiles with U-section, the outer sheet metal profile at its ends each one the legs of its U-section connecting and provided in the legs of the other smaller sheet metal profile, to the longitudinal axis having oblique slots passing bolts and that the outer metal profile is longitudinally displaceable by a mechanical transmission relative to the fixedly connected to its base smaller sheet metal profile. The solution according to DE-AS 2211685 has only a small Außendurchmesserverstellbereich. As the diameter increases, the mechanical complexity increases, since more clamping elements are required in this case. In order to adapt to the different diameters, strips with reconditioned radii must be placed, which in turn results in additional changeover times. In addition, for the manufacture of coils for transformers, reactors, etc. according to DD-PS 840283 (21 g, 1/01) also an adjustable winding mandrel is known, which is formed of a plurality of rails, which form a cylindrical cage, on the the bobbin to be wound is pushed, wherein the distance between the rails of the cylinder axis in order to adapt to the different diameter of the coil body to be wound is variable. The adjustment of the rails is effected by means of these hinged racks, which are mounted displaceably in a frame and with one or more coupled together, are rotatable about the cylinder axis gears. This solution requires a high mechanical complexity, in addition, only circular coils can be wound and only certain diameter levels are adjustable via a perforated disc provided. Object of the invention The aim of the invention is to provide an adjustable winding mandrel, which is universally applicable and thereby allows a reduction of the changeover times. Explanation of the essence of the invention The invention has for its object to provide an adjustable mandrel, which ensures a large variability of the coil cross-sectional shapes to be produced with a simple structure.
