(54) DEVICE FOR STEPPING SHEETING SHEETS

Devices for charging stator sheets with an internal strainer on the outer diameter, which contain a mechanism for rotating stator sheets, are known.

 in the form of several vertical augers,

I located on the forming a closed cylindrical surface, and stop

 knot.

The proposed device will allow continuous, automatic

 Charge of several stator disks of electronic machines with simultaneous collection of oriented sheets on charge mandrels. It is characterized in that the locking assembly is made in the form of two vertical oriented skalok, having a cylindrical lead-in, conical pedestrian and cylindrical orienting parts and located adjacent to each other at a distance equal to the distance between the batch mark and the adjacent groove under the stator bracket sheet.

The ciclical parts of the rolls do not exceed the depth of the charging plate and the groove under the stator bracket.

Auxiliary rollers vertically adjacent to the augers are used in the device to prevent collapsing on the screws of the charge plate and the slots for the stator brackets of the stator sheet, while the distance between each roller and the adjacent screw is not multiple of the distance between the slots under the bracket and the distance between orienting rolling pins.

FIG. 1 shows the front view of the device; in fig. 2 - top view; . 3 orienting pin configuration; in fig. 4 - the position of the deformed stator sheet to the orientation and in the oriented position.

The bottom 1 and top 2 frames of the device body are rigidly connected to each other by columns 3. Support frames 4 and 5 are fastened to the frames, in which four leading screws 6 and two auxiliary rollers 7 are mounted. Toothed cutting on the lower turns of the screws is in engagement with

internal teeth of the ring 8, which has an external gear cutting. The outer teeth of the ring are engaged with gear 9, which sits on the lower part of the roller 10. At the upper part of the latter sits a tester, 5 N 11, which is in engagement with the shaft gears 12, fixed on the bracket 13, and the gear shaft 12 is connected via a belt transmission 14 with two orienting rolling pins 15. The lower ends of the rolling sticks are mounted on the support plate 16. To the same plate on the bracket 17, an electric motor 18 is fastened, the shaft of which is connected to the roller 10 by a belt drive 19.

The orienting pin (Fig. 3) has a 15 cylindrical feed part 20, a conical transitional part 21 and a cylindrical orienting part 22. The difference

The radii of the orienting and lead-in parts are equal to the depth of the charging groove 23 of the sheet 20 24 Sh1k more: it. The width and depth of the screw auger are equal to the width and depth of the groove 25 of the sheet 24 intended for the bracket, which allows the orientation rolling pins to be the same. The leveling groove may be round and rectangular. Screws 6, auxiliary rollers 7 and:, the lead-in parts 2O of the orienting rolls form a closed vertical cylindrical surface, with the hollows of the screws, 30 of the rolls and the lead-in parts of the rolls touching an imaginary circle, the diameter of which is equal to the outer diameter of the stator plate.

The distance between the rolling pins 15 is equal to 35 the distance between the blended mark 23 and the nearby groove 25, and the rollers 7 are removed from the nearby screws 6 by a distance not multiple to the distance between the puzzles and not equal to the distance between the rolling pins.

The device works as follows.

The rotation of the electric motor 18 is transmitted through a belt drive 19 to the roller 1O, the gear 9 and 11 is seated on it, and the gears 9 and 11 are transmitted accordingly.

knuckle 8 and a gear shaft 12. The ring 8 turns up the leading shnecky 6, and the gear shaft 12 rotates orienting rolling pins 15 through a belt drive 14.

The stator sheets 24 fall from the tray 26 onto the turns of the screws 6, which, rotating, feed them down. In the area of the lead-in part 55 2 O skalok sheets move with the screws down, located freely in the depressions of the screws. Continuing to forcibly lower, the sheet slides onto the tapered portion of the 21 rollers. On a cylindrical orientation - 60

The spherical part 22 is fed elastically deformed due to the fact that the radius of the orienting part is larger than the lead radius.

/ Being located in the space bounded by the screws 6, the orienting part 22 ska, the block and the auxiliary rollers 7, the sheet continues to be forcibly rotated by arrow A (Fig. 4) until the charging groove 23 and the groove 25 are simultaneously pulled onto the orienting parts 22 of the rods. The sheet oriented in this way spreads out and continues, without rotation, to descend on the blender (not shown).

The auxiliary rollers 7 during the blending process rotate freely in the centers and prevent the grooves 25 or the mounting groove 23 of the sheet 24 from falling into the screws 6.

Item of gain

1. Arrangement for storing sheets of stator sheets with an inner charging sign on the outer diameter of the sheet, containing a mechanism for rotating the stator sheets in the form of several vertical augers located but forming a closed cylindrical surface, and a stop assembly, characterized in that reliability

and blending performance, the stopper unit is made in the form of two vertical orienting skalok, having a cylindrical lead-in, conical transitional and cylindrical orienting parts and located close to each other at a distance equal to the distance between the blended sign and the adjacent stator bracket sheet.

2. Settled, p. 1, so that, in order to ensure the free passage of the sheets after their blending, the difference in the radii of the orienting and lead cylindrical parts of the scoops does not exceed the depth of the base mark and the slot under the bracket, the stator sheet.

3. A device according to nnii and 2, which is based on the fact that, in order to prevent knocking down the screws of the stitching mark and the slots under the clamped stator sheet, it uses auxiliary rollers located vertically adjacent to the screws, and the distance between each roll and adjacent screw is not a multiple of the distance between the grooves under the staples to not equal to the distance between the orienting rolling pins.
