Description

Изобретение относитс  к горному делу, а именно к коронкам вращательного бурени .The invention relates to mining, namely rotary drilling crowns.

Известны коронки вращательного бурени , в которых применены пр моугольные твердосплавные пластины с острыми углами передней грани.Rotary drill crowns are known in which rectangular carbide plates with sharp angles of the front face are applied.

Цель изобретени  - увеличение износостойкости коронки.The purpose of the invention is to increase the wear resistance of the crown.

Это достигаетс  тем, что пластины твердого сплава выполнены в виде параллелепипеда , рабоча  грань которого имеет форму полуцилиндра.This is achieved by the fact that the plates of hard alloy are made in the form of a parallelepiped, the working face of which has the shape of a half-cylinder.

На чертеже показана предлагаема  коронка в двух проекци х.The drawing shows the proposed crown in two projections.

Коронка состоит из корпуса /, твердосплавной пластины 2 и хвостовика 3. Твердосплавные пластины с одним задним углом заточкиThe crown consists of a body /, a carbide plate 2 and a shank 3. Carbide plates with one sharpening angle

впа ны в пазы коронки под углом 10-20° без заполнени  промежутков между ними и без заделки нх передних граней в корпусе коронки. Пластины выполнены в виде параллелепипеда с рабочей гранью в форме полуцилиндра .sunk into the grooves of the crown at an angle of 10–20 ° without filling the gaps between them and without embedding their front faces in the crown body. The plates are made in the form of a parallelepiped with a working face in the shape of a semi-cylinder.

Предмет изобретени Subject invention

Коронка вращательного бурени , армированна  пластинами твердого сплава, расположенными в наклонных пазах коронки , отличающа с  тем, что, с целью повышени  износостойкости коронки, пластины твердого сплава выполнены в виде параллелепипеда , рабоча  грань которого имеет форму полуцилиндра.A rotary drill crown reinforced with hard alloy plates located in inclined crown grooves, is characterized in that, in order to increase the wear resistance of the crown, the hard alloy plates are made in the form of a parallelepiped whose working face has a half-cylinder shape.
