Description

Существующие способы получени  биметалличес их издели -заливка жидкой бронзы в неподвижную твердую заготовку, центробежный способ и др.-немеют тот недостаток, что стальные заготовки после пре(ДВ:арительного длительного их нагрева в печи сильно окисл ютс  и требуют сложной операции дл  очистки. Кроме того, эти способы дороги и малопроизводительны. Нагрев врапдающейс  стальной заготовки током высокой частоты тоже недостаточно соверщенен и удобен потому, что при переходе на изготовление втулок различных диаметров требуютс  капитальные переделки высокочастотной установки .The existing methods for producing bimetallic products from them — pouring liquid bronze into a fixed solid billet, a centrifugal method, and others — have the disadvantage that steel billets after pre (their long-term heating in the furnace is highly oxidized and require complicated operation for cleaning.) Moreover, these methods are expensive and inefficient. Heating of a high-frequency current that is striking a steel billet is also not sufficiently sophisticated and convenient because, when switching to the manufacture of sleeves of different diameters, ie alteration of the high setting.

В предлагаемо.м способе изготовлени  биметаллических втулок нагрев вращающейс  втулки осунхествл етс  в течение 3-6 мин. при помощи газовых горелок.In the proposed method of making bimetallic bushings, the heating of the rotating sleeve is inspected for 3-6 minutes. using gas burners.

На чертеже изображена схема укреплени  заготовки на токарном стааже и нагрева ее газовыми горелками.The drawing shows a diagram of strengthening the workpiece at the turning stand and heating it with gas burners.

Стальна  заготовка /, обработанна  внутри обычным способом (напри.мер, пескоструйкой и бурой), устанавливаетс  в вертикальном положении на крыщку 2, после чего в заготовку засыпаетс  бронзова  стружка (или кусочки) с добавкой угл , и заготовка закрываетс  крыщкой 3. В такол виде собранна  и временно скрепленна  специальными захватами заготовка укрепл етс  на обычном токарном станке с планщайбой 4 вместо патрона. Нажим на крыщки осуществл етс  пружиной 5, упирающейс  с одной стороны в крышки, а с другой-в упорный подщинник 6. Упор осуществл етс  центром бабки 7 с помощью руко тки 8. Перед установкой заготовки на станок бабка отодвинута и центр ее выдвинут так, чтобы при подводе бабки к заготовке, сначала осуществл лс  нужный нажим , а затем поаходил центр (при закрепленной уже бабке). Вращение станокThe steel blank (processed internally in the usual manner (eg, sandblasted and brown)) is placed in a vertical position on the lid 2, after which bronze chips (or pieces) with the addition of coal are poured into the blank, and the blank is closed with a flap 3. In tacol form The workpiece, assembled and temporarily fastened with special grippers, is fixed on a conventional lathe with a slider 4 instead of a chuck. The flaps are pressed on the spring 5, which rests on one side into the covers, and on the other, into the supporting plate 6. The support is carried out by the center of the headstock 7 using the handle 8. Before installing the workpiece on the machine, the headstock is pushed and its center is extended so that when the grandmother was brought to the workpiece, the necessary pressure was first carried out, and then the center moved (with the headstock already attached).
