SU959173A1 - Mandrel for winding simulators of coils of induction apparatus - Google Patents

Description

The invention relates to electrical engineering and can be used in modeling windings of induction devices made of tape materials, for example, paper foils.

Research, in particular with respect to windings, is performed predominantly on large-scale models made from tape materials, such as foil and paper. This allows you to reduce the consumption of valuable materials and reduce labor costs. However, the time spent on research, in particular on the manufacture of winding models, remains significant / Taii as a winding equipment. The design used for making field windings does not meet the requirements, the prediction is in the production of models.

 A known mandrel for winding electric coils, comprising a winding frame and means of communication with a drive for its rotation. The winding frame of this mandrel consists of a set of supporting elements in the form of metal strips (rails), uniformly spaced around the perimeter of the disks sitting on the shaft. These discs have grooves at the end of the groove for bonding with the supporting elements and screw-and-screw mechanisms for fastening the supporting elements to the disks. To ensure adjustment to the required diameter, there are annular protrusions next to the T-shaped profile for bolting on both end faces of the disks, and the supporting elements are connected to the gears / mounted on the annular projections of the disks l.

The disadvantages of the mandrel - the bulkiness and complexity of the design. Adjusted to a specific diameter, oHa ,, v ..

15 allows the winding to wind only one diameter. To get a winding of a different diameter, the wound modrl must be .. removed or unwound and rebuilt the winding

20 frame by moving away from the center or approaching JC to the center of the supporting elements, which takes considerable time. Since the PAY simulation of windings during the research process requires that the rebuild should be repeated with a mkogoklotlo, therefore, the duration of the research program will be longer. Since the supporting and other elements are made of metal,

This research directly on the mandrel is generally impossible and all models must be removed from it. The closest to the technical essence, the proposed one is a mandrel for winding electric to carcasses. In the known mandrel, the shaft is telescoped, which allows adjusting its various lengths (axial dimensions) of the windings 2. Its disadvantages are the same as previously described. The purpose of the invention is to simplify the design and increase productivity by simplifying the settings and the possibility of simultaneous winding different models on the same device The goal is achieved by the fact that the frame, the mandrel is made in the form of several hollow cylinders mounted telescopically, and sleeping by fixing elements, located at the ends connected between fighting cylinders. In addition, the cylinders are made of electric. Fig. 1 shows a winding frame of a mandrel with windings of three different diameters wound on it; models of windings; 2 - t, oh, but the cylinders are extended, so that the two windings are arranged concentric. : The mandrel for winding winding models of inductive devices contains a winding frame in the form of several, for example four, telescopically connected cylinders 1 of dielectric, for example bakelite, and a means of communicating with its rotation. (Not shown). For fixing the cylinders 1, holes 2 for pins or screws 3 are provided at their ends. The mandrel works as follows. Depending on the required number of windings and their diameter, the corresponding cylinder 1 is pulled out and securely fastened between screws with screws 3. The end of the wetting material (the foil tape with the paper tape attached or glued to it) is attached to the desired cylinder and, when the frame rotates, the disking coil is wound in the form of 4 from a set of concentric turns. After winding one coil, transition 5 is performed and the next cadget is carried out, etc. until the required number of coils is required. When the winding of one winding is completed, the winding is wound on another cylinder. Possible simultaneously. winding two or three windings of different diameter. If it is necessary to obtain concentric windings (MOTKaVa winding, see Fig. 2), it is necessary to shift the cylinder of a larger diameter with the winding wound around it so that the smaller diameter cylinder with a winding on it will turn out to be inside a cylinder of a larger diameter. With the rotational drive disconnected, a series of studies can be carried out directly on the mandrel, without removing it from the coiler. Simplify customization; .and the possibility of winding several windings of different diameter on one device reduce the time spent on carrying out the research program. Claim 1.
