Description
Изобретение относится к пневмоударному буровому инструменту, конкретно к буровым коронкам со штыревыми породоразрушающими вставками.The invention relates to a pneumatic percussion drilling tool, specifically to drill bits with pin rock-cutting inserts.
Цель изобретения - повышение стойкости.The purpose of the invention is to increase durability.
На чертеже изображена коронка, вид сверху.The drawing shows a crown, top view.
Буровая коронка содержит корпус 1 с головной частью, армированной штыревыми породоразрушающими вставками, из которых периферийные 2 установлены попарно и взаимно параллельно. Между их основаниями установлены вставки 3 второго ряда, при этом их диаметр и расстояние от периферии обеспечивают перекрытие непрорабатываемой зоны в процессе бурения. Λ The drill bit contains a body 1 with a head part reinforced with pin rock-cutting inserts, of which the peripheral 2 are installed in pairs and mutually parallel. Inserts 3 of the second row are installed between their bases, while their diameter and distance from the periphery provide overlapping of the undeveloped zone during drilling. Λ
За счет увеличения диаметра штыревых 3 вставок второго ряда и устранения непрорабатываемой зоны стойкость коронки повышается на 10-15%.By increasing the diameter of pin 3 inserts of the second row and eliminating the unworkable zone, the durability of the crown is increased by 10-15%.
