Description
Предлагаетс способ изготовлени коллекторов дл электрических машин с образованием коллекторной втулки из пластмассы, путем опрес совывани этой пластмассой коллекторных пластин.A method is proposed for manufacturing manifolds for electric machines with the formation of a collector sleeve made of plastic, by pressing this plastic into collector plates.
По этому способу, с целью упрощени технологии, сокраи1ени р бочего времени и снижени расхода коллекторной .меди, предлагаетс из листовой меди штамповать заготовки в виде полос с зубчатыми кромками . Полосы изгибают на оправках в кольца, зубцы отгибают внутрь кольца с образованием петушков и заготовку онрессовывают пластмас сой дл образовани втулки, после чего разрезают заготовку по образующим поверхности коллектора на отдельные коллекторные пластины.According to this method, in order to simplify the technology, to reduce the working time and to reduce the consumption of collector media, it is proposed to stamp billet from copper sheet into stripes with serrated edges. The bands are bent on mandrels into rings, the teeth are bent inward into the ring with the formation of males and the billet is pressurized with plastic to form a sleeve, after which the billet is cut into the individual collector plates forming the surface of the collector.
На фиг 1 изображена конфигураци медной заготовки после штамповки; на фиг. 2 - две проекции заготовки - согиутой в кольцо и опрессованной пластмассой; на фиг. 3 и 4 - готовый коллектор после разрезани опрессованной заготопки на отдельные коллекториые пластины.Fig. 1 shows the configuration of the copper billet after stamping; in fig. 2 - two projections of the workpiece - constricted into a ring and pressed plastic; in fig. 3 and 4 — the finished collector, after cutting the pressurized slag, into separate collector plates.
Технологический процесс изготовлени коллекторов по предлагаемому способу cociloHT из следующих операций.The technological process of manufacture of collectors according to the proposed method of cociloHT from the following operations.
Сначала штампуетс медна заготовка. Штамповку можно производить либо на компаундиом штампе, либо па специальном штампе путем «выкатываии профил . Длина заготовки определ етс числом пластин изготовл емого коллектора. Затем производитс изгиб заготовки в кольцо на специальной оправке и отгибание ее концов па гибочном штампе с образованием петушков. Опрессовка заготовки пластмассой производитс в обычной пресс-форме и технологический процесс не отличаетс от существующего. Последней операцией вл етс разрезание коллектора на отдельные коллекториые пластины и одновременна фрезеровка шлицов в петушках.First, the copper blank is stamped. Stamping can be done either on a compound stamp or on a special stamp by “rolling out the profile. The length of the workpiece is determined by the number of plates produced by the collector. Then the workpiece is bent into a ring on a special mandrel and its ends are bent over by a bending stamp with the formation of males. Pressing the preform with plastic is carried out in a conventional mold and the technological process does not differ from the existing one. The last step is to cut the collector into separate collector plates and simultaneously milling the slots in the males.
Дл высокооборотных двигателей (свыше 12000 об/мин), имеюших длинный коллектор (свыше 25 мм без петушков), с целью упрочнени коллектора может быть нредложена дополнительна запрессовка в него металлических колец.For high-speed engines (over 12000 rpm), having a long collector (over 25 mm without cockerels), in order to strengthen the collector, additional pressing of metal rings into it can be proposed.
