Description
(54) ПОРОДОРАЗРУШАЮЩИЙ ИНСТРУМЕНТ(54) BORING TOOLING TOOLS
из двух участков 6 и 7, расположенных под разными углами к их задним гран м 8. Боковые грани скалывател выполнены расход щимис к хвостовику 9, а угол заострени скалывател f i меньше угла заострени -fi каждого из рабочих элементов, при этом угол заострени .г больше угла заострени fifrom two sections 6 and 7 located at different angles to their rear edges 8. The side faces of the cleaver are divergent to the shank 9, and the cleavage angle fi is smaller than the angle of angle -fi of each of the working elements, and the angle of angle .g is larger sharpening angle fi
При контакте инструмента с забоем опережаюшие рабочие элементы, внедр сь в забой, создают опережающий вруб и напр женное состо ние массива между рабочими элементами. Затем при контакте режущей части скалывател с массивом создаетс направленна трещина в массиве между рабочими элементами, что приводит к отрыву разрушаемой части породы от массива .When the tool comes into contact with the face, the advanced working elements, embedded in the bottomhole, create a leading edge and tight state of the array between the working elements. Then, upon contact of the cutting part of the cleaver with the massif, a directional crack is created in the massif between the working elements, which leads to the separation of the rock to be destroyed from the massif.
