Description

1one

Изобретение относитс  к буровой технике.The invention relates to a drilling technique.

Из1вестны буровые коронки, содержап.и1е корпус, резцедержатели и твердосплавные резцы с острыми скосами на торцах.Known are the drill bits, the body and the body, the tool holders and carbide cutters with sharp bevels on the ends.

Предлагаема  коронка отличаетс  от известных тем, что передн   грань каждого резцедержател  выполнена со сквозным поперечным , в котором установлены резцы, конта ,ктирующие своими острыми скоса-ми на торцах с противоположными гран ми паза. Это повышает надежность закреплени  резцов в резцедержател х.The proposed crown differs from the known ones in that the front face of each toolholder is made with a transverse cross-section, in which incisors are installed, which cite with their sharp bevels on the ends with opposite sides of the groove. This increases the reliability of fixing the incisors in the tool holders.

На фиг. 1 изображена предлагаема  коронка , вид в плане; на фиг. 2 - твердосплавный резец.FIG. 1 shows the proposed crown, a plan view; in fig. 2 - carbide cutter.

Коронка состоит из корпуса 1 и установленных в его пазах резцедержателей 2. Передн   грань каждого резцедержател  2 выполнена со сквозным поперечным пазом а, в котором устанавливаютс  твердосплавные резцы 3. Резцы 3 выполнены с остры-ми скосами 4 на торцах, которыми они контактируют с противоположными гран ми пазов а резцедержател  2.The crown consists of a housing 1 and tool holders 2 installed in its grooves. The front face of each tool post 2 is made with a through transverse groove a in which carbide tools 3 are installed. The cutters 3 are made with sharp bevels 4 at the ends with which they contact opposite edges mi grooves and tool holder 2.

Предмет изобретени Subject invention

Бурова  коронка, содержаща  кориус, резцедержател и твердосплавные резцы с острыми скосамн на торцах, отличающа с  тем, что, с целью лавышени  надежности закреплени  резцов в резцедержател х, иередил  грань каждого резцедержател  выполнена со сквозным понеречны.м пазом, в котором установлены резцы, контактирующие своими острыми скосами на торцах с противоположными гран ми паза.The crown containing corus, tool holder and carbide cutters with sharp scoops at the ends, is characterized in that, in order to make the cutters secure in the tool holders, the cutting edge of each tool holder is made with a through hole in the m. with their sharp bevels at the ends with opposite edges of the groove.
