The invention relates to technological equipment for manufacturing the magnetic circuits of transformers and chokes and can be used in electrical and radio engineering.

The purpose of the invention is to increase productivity.

FIG. 1 shows the device, a general view; in fig. 2, node I in FIG. one; in fig. 3 shows section A-A in FIG. one.

A support 1 is installed on the guides of the bed 2. The support of the support 1 to the mandrel 3, onto which the magnetic core is wound, is provided by a pneumatic cylinder 4. On the back side of the pressure plates 5 there is a finger with which the plate is connected to the sleeve 6. Between the sleeve 6 and the pressure plate 5 a calibrated spring of 7 or more is installed. The sleeve 6 is pivotally connected to one arm of the lever 8. The lever 8 is connected to the pusher 9. The lever 8 is supported in the hinge connection 10 with the rotor 11. The rotor 11 is installed in the bearing assembly 12 coaxially with the spindle 13 of the winding machine.

Pushers 9 are installed in guide sleeves 14 provided in the rotor 11. On the pushers 9, rolling elements are installed in the form of rollers 15 and 16, which are used to connect the pushers with a copier, which is a flat pressure sector 17, mounted on rails 18 of the caliper 1 and connected to the pneumatic cylinder 19, which preloads the sector 17 with a predetermined force, and the deflecting sector 20, which has a helical surface and is rigidly fixed to the support 1. The pusher element 15 serves to contact the copier sector 17, the roller 16 - to contact with sector 20 copier.

The device works as follows.

The mandrel 3 is mounted on the rotor 11, then pressure is applied to the pneumatic cylinder 4, the caliper 1 moves and clamps the mandrel between the spindle 13 and the rotor 11. The mandrel is taped and fixed, then pressure is applied to the pneumatic cylinder 19, the pressure sector 17 moves and acts on rollers 15. Accordingly, the pushers 9 move, which rotate the levers

8, and the pressure plates 5 are moved until contact with the mandrel 3. The axial movement of the pressure sector 17 is also stopped in the pneumatic cylinder

5 19 set pressure is set. The machine engine is turned on and the winding process begins. During the winding process, the pressure plates 5 must be deflected from the path of the winding tape in a plane perpendicular to the axis of rotation. This movement of the pressure plates 5 is provided as follows:

clamping sector 17 in the area of motion 1 ".

- tape on the mandrel 3 has a gap, and

deflecting sector 20 helix.

When the rotor 11 rotates, the element 15, resting on the pressure ring 17, after 20 pg3 pusher 9, the lever 8, the sleeve 6 and the spring 7, ensures that the pressure plate 5 is pressed against the ribbon on the mandrel. After the pressing sector 17 has passed, the element 15 loses its support, the element 16 hits the deflecting sector 20 and through the pusher 9 rotates the lever 8, which deflects the pressure plate 5 in a plane perpendicular to the axis of rotation of the rotor 11. As soon as the rotor 11 rotates yi-ol, which corresponds to the insertion of a tape on a mandrel, the deflecting sector 20 is interrupted, element 16 loses its support, and element 15 hits a screw-like lifting of the pressing sector 17, pushes the lever 8 and, accordingly, the pressing plate 5 into the pressed position. This operation is carried out sequentially with each plate from the plates in accordance with the angular position of the rotor. After winding the specified thickness, the spindle of the machine stops, the last turn is fixed and the tape is cut off. The pressure is relieved from the pneumatic cylinder 19, and pneumatic cylinder 4 is pressurized to move the slide 1 from the spindle.

The magnet core with mandrel is removed from the machine. The winding process is over.
