Description

При отливке корпусов долот известными способами формовки вес прибыли получаетс  равиым весу самой отливки корпуса, а отходы металла в виде стружки при механнческоС его обработке составл ют около 45% веса корпуса.When casting cases of bits by known methods of forming, the weight of the profit is obtained by the ravi weight of the body casting itself, and the waste metal in the form of chips during mechanical processing is about 45% of the weight of the body.

Предлагаел ый способ отличаетс  от известиых тем, что корпуса формуют попарио лапал и (тоикими част ми) вверх, с виутреииими етержп ми в одной обш.ей дл  двух корпусов закрытой прибылью, расположеииой между ии.ми действующей под атмосфериым давлением и питающей средиюю часть корпусов. Это позвол ет получать плотные отливки при значительном сокраихенин нх веса и трудоемкости изготовлени .The proposed method differs from the limestone in that the shells are molded popario and (tokimi parts) upwards, with visibility in one common area for two shells with a closed profit located between atmospheric pressure and a part of the shells . This makes it possible to obtain dense castings with significant co-cracking of their weight and labor intensity.

Па фиг. 1 показан вид собранной формы в плане: на фнг. 2 - разрез ее по А-А фиг. 1; иа фиг. 3 - разрез ее по Б-Б фиг. 1.Pa figs. 1 shows a view of the assembled form in the plan: fng. 2 is a section through it, A-A of FIG. one; FIG. 3 is a section through BB in FIG. one.

Формовка выполнена в двух опоках: нижней / и верхней 2 по разъeMHoii модели 3.Molding is performed in two flasks: the lower / upper 2 on the connector MHoii model 3.

Металл дл  питани  двух корпусов одновремеино подводитс  в средщою часть (в гр зевый канал на уровне промывочной плиты) каждою корпуса питател ми 5 через закрытую прибыль 4.The metal for feeding the two bodies at the same time is supplied to the middle part (to the throat channel at the level of the wash plate) by each body with feeders 5 through a closed profit 4.

Дл  обеспечени  выхода из нее газов во врем  заполнени  металлом нижней и средней части корпусов прибыль 4 сообщаетс  с атмосферой посредством выпора 6 с щамотиой воронкой 7 над ним.In order to allow gases to escape from it during the filling of the lower and middle parts of the bodies with metal, the profit 4 is connected to the atmosphere by means of the outlet 6 with the ground funnel 7 above it.

Дл  обеспечени  действи  прибыли 4 под атмосферным давлением она сообщаете  е атлюсферой поередством газопроницаемого стержн  ;S с расиоложенным над ним предохраннтельным стаканом 9 с отверетием .To ensure the effect of profit 4 under atmospheric pressure, it communicates the e-sphere with an alternating gas-permeable rod; S with a safety cup 9 located above it with a hole.

Металл подводитс  в нижнюю часть прибыли на уровне разъема опок питателем 10 через щлакоуловнтель 11, собранный из шамотных трубок, литниковый сто к 12 и шамотную воронку 13, помещенную з центрирующей ее опоке 14.The metal is brought to the lower part of the profit at the connector level with a flask by a feeder 10 through a clapboard 11 assembled from fireclay tubes, a gate to 12 and a fire funnel 13 placed from the centering flask 14.

Дл  предохранени  от засорени  формовочной землей питатель 10 перекрываетс  шамотной плиткой 15.In order to protect the ground from clogging up, the feeder 10 is covered with a chamotte tile 15.

Форма корпусов бурильных долот при описанном способе формовки получаетс  при примененин дл  каждого корпуса только одного центрового внутренпего стержн  16.The shape of the drill bit bodies with the described molding method is obtained by using only one centering inner rod 16 for each case.

Предмет изобретени Subject invention

Способ отливки корпусов бурильных долот, отличающийс  тем, что, с целью обеспечени  получени  плотных отливок и значительного сокраш,ени  их веса, корпуса формуют попарно лапами (тонкими част ми) вверх, с внутренними стержн ми, с одной общей дл  двух корпусов, закрытой прибылью, расноложенной ними действующей иод атмосферным давлением и нитающей среднюю часть корпусов.The method of casting drill bit cases, characterized in that, in order to ensure dense castings and significant cutting, their weights, the bodies are molded in pairs with legs (thin parts) upwards, with internal rods, with one common for two cases, closed profit , disposed of the current iodine atmospheric pressure and threading the middle part of the buildings.
