(54) DEVICE FOR ASSEMBLY OF MAGNETIC WIRES

I

The invention relates to process equipment for the production of transformers and is used in the electrical industry for assembling magnetic cores.

A device for assembling magnetic circuits is known, comprising a frame, a limiter corresponding to the external contour of the magnetic circuit, an assembly table on which a limiter is installed, corresponding to the internal contour of the magnetic core DD

However, in the known device during assembly it is possible to skew the plates of the magnetic circuit or to exceed the allowable gap in the joints of the plates, which reduces the quality of the manufactured products.

The purpose of the invention is to improve the quality of manufactured products.

The goal is achieved by the fact that the device for assembling the magnetic cores of electrical machines contains a mandrel with a conical inner surface of rectangular cross section mounted on a frame, and an assembly table is located inside the mandrel, while a stop corresponding to the outer contour of the magnetic circuit is installed inside the mandrel.

In addition, on the inner surface of the mandrel is made of longitudinal grooves, and each of the limiters corresponding to the outer contour of the magnetic circuit, made in the form of a rotary lever mounted in the longitudinal groove and provided with a drive.

FIG. 1 shows a device for assembling magnetic cores; Figure 25 shows the sequence of the assembly of the magnetic conductor; figure 6 - Assembly table with a limiter corresponding to the outer contour of the magnetic circuit.

The device for assembling magnetic cores consists of an assembly table I, on which a limiter 2 is installed, corresponding to the internal contour of the magnetic circuit. Table I is equipped with fur3

the height of the vertical displacement 3, consisting of the lead screw, a pair of conical gears, the electromagnetic clutch 4, the gearbox 5 and the electric motor 6, mounted on a movable carriage 7 moving along one hundred Nina 8 (after a set of magnetic circuit) to the installation for crimping and welding 9

. The device contains six unwinding mechanisms 10 with coils of rolled steel, six correct devices 11, six tensioning devices 12, three pairs of feeding mechanisms 13 rigidly connected to each other, six guillotines 14, a device 15 and an unloading trolley 16.

A frame 1 is fixed to a mandrel 1 with a conical inner surface of rectangular cross section, and an assembly table 1 is located inside the mandrel 17. In the longitudinal grooves inside the mandrel 17, limiters 18 are installed, made in the form of a rotary lever, equipped with a drive. Three pairs of feeders 13 are labeled 19-24,

The device for assembling the agnostas operates as follows;

The reel of the steel steels are installed in the unwinding mechanisms 10 and the ends of the belts are threaded 5 through the rules, H6ie and tensioning devices 1 1 and 12 into the feeding mechanisms 13. After the installation in automatic mode, the feeding mechanisms 13 are turned on and the lengths of coiled steel are equal ) on the assembly table 1, and the guillotines 14 9 cut the tape into the specified size.

After filing three-dimensional pieces of coiled steel, the feeding devices 19-21 under the guillotines 14 and their lengths into a given plate size slide along an inclined plane and occupy a position on the assembly table 1 shown in Fig. 2, while three other feeding devices 22-24 are mc in the OPTOPOCHOKNOM position at a distance equal to the specified size of the plates of the magpptroy.

After supplying the control signal, the feeding devices 22-24 supply the measured lengths of coiled steel but ;; guillotines14 and at the same time limiters, send the pre-laid plates to a given i-size (size), thus forming the first layer of magnet collected

- pipeline (fig.Z). After cutting the plates fed by the feeding devices 22-24, the plates slide along an inclined plane and take a position on

The assembly table 1 shown in Fig. 4, wherein the feeding devices 19-21 occupy the opposite position at a distance also equal to the predetermined size of the plates of the magnetic conductor.

After supplying the control signal, the feeders 19-21 serve the measured lengths of coiled steel under the guillotines and at the same time limiters and

5, the pre-laid plates are sent to a predetermined position (size), thus forming the second layer of the assembled magnetic circuit (FIG. 3).

About B the assembly process of the magnetic circuit assembly table 1 is lowered at a constant speed equal to the thickness of the assembled magnetic circuit plates in

Time unit.

After laying a specified amount

The layers of the magpito drive of the electric drive of the table 1 are turned on by accelerating the descent of the table to the t-junction of the fixed supports, which were placed on the ground carriage 7.

The carriage 7 moves the assembly table 1 to the installation for crimping and welding the magnetic circuit. After the end of the welding, the removable device 15 transfers the magnetic conduit from the assembly table 1 to the discharge carriage 16.

The device makes it possible to improve the quality of the manufactured products due to the precise fixing of the magnet plates with the grabber and the hopper surfaces of the mandrel.
