Description

Изобретение относитс к технологии изготовлени торцовых коллекторов электрических машин и может быть использовано в электротехнической промышленности.The invention relates to the technology of manufacturing end collectors of electrical machines and can be used in the electrical industry.

Известен способ изготовлени коллектора , внлючгющий образование одного р да опорных выступов, вырубание гребенки, формирование диска, опрессовку диска пластмассой/ в корпус коллектора с последующей механической обработкой 1.A known method of manufacturing a collector includes the formation of one row of supporting protrusions, the cutting of the comb, the formation of a disk, the pressing of a plastic disk / into the body of the collector, followed by machining 1.

Недостатком известного способа вл етс увеличенный расход материала и недостаточна прочность креплени пластин.The disadvantage of this method is the increased consumption of material and insufficient fixing strength of the plates.

Наиболее близким по технической сущности к предложенному изобретению вл етс способ изготовлени торцового коллектора электрической машины путем вырубки из ленты гребенки с пластинами и опорными выступами, расположенными на одной ее стороне, формировани диска из гребенок, опрессовки диска пластмассой в корпус коллектора и последующего механического разделени пластин 2.The closest in technical essence to the proposed invention is a method of manufacturing an end collector of an electric machine by cutting a comb with plates and supporting protrusions located on one side of it, forming a disk from the combs, pressing a disk into plastic into the collector body and then mechanically separating the plates 2 .

Недостатком известного способа вл етс то, что при изгибе опорных выступов ИГ заготовки равной толщине ленты, образуютс большие радиусы, что вызывает увеличение ширины ленты и, следовательно, увеличение расхода меди.The disadvantage of this method is that when the IG workpiece bends have a bend equal to the thickness of the tape, large radii are formed, which causes an increase in the width of the tape and, consequently, an increase in copper consumption.

Цель изобретени - экономи материала .The purpose of the invention is to save material.

Поставленна цель достигаетс тем,что по кра м ленты с двух сторон выдавливают углублени в местах The goal is achieved by squeezing out the recesses in the places along the edges of the tape from two sides.

0 образовани опорных выступов, причем на каждой стороне ленты углублени располагают в шахматном пор дке, затем в местах углублений, расположенных друг против друга на разных сторонах ленты выполн ют с одной сто5 роны окно, а с другой прорезь, отгиба при этом материал ленты в сторону образовани углублений, затем вырубают гребенки по лини м, соедин ющим Formations of supporting protrusions, on each side of the ribbon, the recesses are arranged in a checkerboard pattern, then in the places of the recesses located opposite each other on different sides of the ribbon, a window is made on one side and a tape is cut on the other side. recessing, then combs are cut down along the lines connecting

0 плоскости противоположных окон, расположенных под углом к кра м ленты.0 planes of opposite windows located at an angle to the edges of the tape.

Сущность изобретени по сн етс чертежами, где на фиг. 1 показано выполнение предварительных углубле5 ний; на фиг. 2 - образование опорных выступов при просекании окон и прорезей в местах, предварительных углублений; на фиг. 3 - вырубка гребенок пластин дл коллектора, на фиг. 4 - свернутый в кольцо пакетThe invention is illustrated in the drawings, where in FIG. 1 shows the implementation of preliminary deepening; in fig. 2 - formation of supporting protrusions when prosekaniya windows and slots in places, preliminary recesses; in fig. 3 shows the cutting of the dies of the collector plates; FIG. 4 - rolled package

Claims

0 a collector from a comb of plates; in FIG. 5 - plastic-compressed manifold with divided plates. The manufacture of the face collector occurs in the following sequence. On tape 1 (Fig. 1), the thickness of which corresponds to the thickness of the collecting plate, on its edges on both sides, depressions 2 and 3 are squeezed out at the places where the support protrusion is formed, and on each side of the tape the depressions are arranged in a checkerboard pattern. Then the bottom of the recesses 2 is cut through, the supporting protrusions are curved towards the sides of the recesses and the half of the windows are formed on both sides of the tape, and the protrusions formed thereby are bent towards the formation of the recesses (Fig. 2). Against the support protrusions 4, made when the window 2 is penetrated, a support protrusion 5 is provided, which is formed when a slot 6 is formed. During the next operation, two combs, consisting of collector plates 7, are cut out of the tape along lines connecting the planes of the opposite windows located at an angle to the edge of the tape (fig.Z). Next, each comb is bent to form a disk 8 (figure 4), the plates in which are connected by jumpers 9 located on the periphery of this disk and are separated by radial grooves 10. Then the disk 8 is pressed by plastic 11 into the collector case (figure 5), which penetrates into grooves 10. forms between plastisi and insulating layer. During subsequent machining of the outer diameter of the disk 8, jumpers 9 are removed and the plates are separated. The invention makes it possible to save material by more fully utilizing the area of the tape, since the support protrusions for fastening the plates are formed from those parts of the tape that are not used to form the plates. The invention of the method for producing an end collector of an electric machine by cutting a comb with plates and supporting protrusions located on one side of it, forming a disk from combs, pressing a disk with plastic into the collector body and then mechanically separating the plates in order to save material, along the edges of the tape on both sides, there are squeezed out recesses in the places of formation of supporting protrusions, and on each side of the tape the recesses are arranged in a staggered order, then In the places of the recesses located opposite each other on different sides of the tape, a window is made on one side and, on the other, a bend, thus bending the tape material towards the formation of recesses, then cutting dies along the lines connecting the planes of the opposite windows, angled to the edges of the tape.
