Description

The invention relates to a technology for manufacturing collectors of electrical machines and can be used in the electrical industry in the manufacture of collectors on plastic. A known method of manufacturing collectors of electrical machines on plastic housings with plastic insulation between the current-carrying plates; on which the collectors are made by plastic pressing a plate package between which technological gaskets are installed, which are removed after plastic is pressed on the collector. When assembling, the collector plates are installed in the grooves of a toothed cylindrical support placed in an expanding conical ring, the number of grooves of which is equal to the number of platinum. The mandrel from the outer surface of the expanding conical ring is uncoupled by a spring element, after which the specified gaskets are inserted between the plates. Til The disadvantage of this method is a large waste of copper during the stamping of the plates. Closest to the proposed method of manufacturing the collector of an electric machine, including the manufacture of a coolector billet by corrugating the core of the conductor with the punch and forming elements of the tape, rolling the billet into a ring, placing insulation pads between the collector plates with a gasket height equal to the height of the collector plate, setting the ring to technological casting, crimping of insulating gaskets by squeezing the sides of the corrugations, pressing the ring with plastic and removing the mandrel 121, H The advantage of this method is that when installing insulating gaskets in the paes between the corrugated lines on the working side of the collector and further crimping the mandrel ring, it is possible to displace the insulating gaskets and remove them, especially , which reduces the quality of manufactured products. The purpose of the invention is to improve the quality of the manufactured products by eliminating the displacement of the insulation pads. This goal is achieved in that according to the method of manufacturing the collector of an electrical machine, including the manufacture of a collector blank by corrugating the conductive material with a punch and forming elements, rolling the blank into a ring, placing insulation pads between the collector plates with a pad height equal to the height of the collector plate, installing rings in the technological mandrel, crimping of insulating gaskets by squeezing the sides of the corrugations, separation of collector plates, Pressing the ring with plastic and removing the mandrel, placing the insulation pads before the corrugation of the tape, positioning them across the width of the belt in increments equal to the height of the collector plate, during the corrugation, the punch is placed along one of the edges of the insulation pads, and the molding elements. Fig. 1 illustrates the process of corrugating a tape of a conductive material; Fig. 2 shows a part of the collector billet, .3 is an embodiment of the collector billet, Fig. 4 shows the collector of an electric machine with a mandrel. The manufacture of the collector of the electric machine is carried out in the following technological sequence. nosti. A tape of conductive material 1, for example copper, (FIG. 1), having a width equal to the length of the collector, is fed, in increments equal to the pitch of the collector plates, to the isolation zone 2 by a mechanism made in the form of two rollers 3. In the isolation zone 2 along the width of the tape 1, an insulating gasket 4c, uarcwi, is placed equal to the collector height. plate, and with the help of a roller heater 5 stick it. Then, the tape 1 is fed from the insulating zone 2 to the corrugated b zone, where the punch 7 is formed by the corrugation 8. The punch 7 is placed along the edge of each insulating pad 4, bringing the head of the punch 7 to its edge. After molding, the punch 7 outputs and compresses the corrugations 8 by means of toothed forming elements 9, pressing the insulating spacers 4. After compression, the forming elements 9 are retracted and the belt 1 is moved to a step equal to the height of the collector plate and the cycle is repeated. The current-length elements are cut from the thus prepared length, rolled up and placed into the process mandrel 10, after which the connecting part of the corrugations 8 is removed and the sleeve 11 is inserted into the center of the assembly mandrel 10 to form a shaft hole. Then the ring is pressurized with insulating material, for example, re-actoplast 12. After crimping, the finished collector is removed from. the mandrels 10 and, if necessary, the outer surface of the collector is processed or calibrated to obtain a collector consisting of U-shaped plates separated from each other by an insulating pad 4.

Similarly, electric collectors are made of a band

material with protrusions for connecting a collector with a winding (Fig. 3).

The invention improves the quality of the manufactured products by eliminating the displacement of the insulation pads.
