Description
(54) РЕЗЕЦ ДЛЯ ГОРНЫХ МАШИН(54) CUTTER FOR MOUNTAIN MACHINES
1one
Изобретение относитс к горной промышленности, а именно к резцам исполнительных органов горных машинThe invention relates to the mining industry, namely to the incisors of the executive bodies of mining machines.
По ОСНОВНОМУ авт.св. № 717327 известен резец дл горных машин,включающий с рабочей головкой и установленный в отверстии державки износостойкий элемент в виде набора кернов, расположенных последовательно , при этом головки кернов ориентированы в одном направлении pj .BY MAIN Auth.St. No. 717327 is known a cutter for mining machines, comprising with a working head and a wear-resistant element mounted in the hole of the holder in the form of a set of cores arranged in series, the core heads being oriented in the same direction pj.
Недостатком резца вл етс то, 4JO после поломки или выпадани одного из кернов происходит значительное увеличение усили резани вследствие большой площади контакта ра- . бочей головки с разрушаемой породой .The disadvantage of the cutter is that 4JO after a breakdown or loss of one of the cores there is a significant increase in the cutting force due to the large contact area. bachaea head with destructible rock.
Цель изобретени - снижение.усилий резани при обнажении очередного керна.The purpose of the invention is to reduce cutting effort when stripping the next core.
Поставленна цель достигаете тем, что резец дл горных машин, включающий державку с рабочей головкой иThe goal is achieved by the fact that the cutter for mining machines, including the holder with the working head and
установленный в отверстии рабочей головки износостойкий элемент в виде набора кернов, расположенных последовательно , снабжен расположенным в отверстии державки полым цилиндром , в котором установлены керны, а рабоча головка выполнена из кольцеобразных элементов.A wear-resistant element installed in the working head hole in the form of a set of cores arranged in series is provided with a hollow cylinder located in the holder hole, in which cores are mounted, and the working head is made of ring-shaped elements.
На фиг. 1 показан резец дл горных машин, общий вид; на фиг.2 - раз FIG. 1 shows a cutter for mining machines, a general view; figure 2 - time
.10 рез А-А на фиг.1..10 cut A-A in FIG.
Резец дл горных машин включает державку 1 с хвостовиком 2 и коничес кой рабочей головкой 3. Хвостовик имеет упор 4. В державке выполнено The cutter for mining machines includes a holder 1 with a shank 2 and a conical working head 3. The shank has an abutment 4. In the holder is made
15 отверстие 5, в котором размещен пот, : лый цилиндр 6. В полом цилиндре уста новлены последовательно керны, состр щие из головки 7 и корпуса 8, между которыми расположена прокладка 9.15 is a hole 5 in which the sweat is placed: a loose cylinder 6. In the hollow cylinder, cores are mounted in series, which are made up of the head 7 and the body 8, between which there is a gasket 9.

Рабоча головка выполнена из коль цеобразных элементов 10 и 11, расположенных на полом цилиндре. Кольцеобразный элемент 10 закреплен наThe working head is made of ring-shaped elements 10 and 11, located on the hollow cylinder. The annular element 10 is fixed on

полом цилиндре, а кольцеобразный элемент 11 свободно посажен между державкой и кольцеобразным элементом 10.hollow cylinder, and the annular element 11 is loosely seated between the holder and the annular element 10.
В процессе работы резца абразивный износ кольцеобразного элемента 10 и полого цилиндра 6 происходит значительно быстрее, чем износ твердосплавного керна. В результате керн огол етс , а затем ломаетс или выпадает . После потери керна и кольцеобра зного элемента 10 по вл етс возгюжнрсть перемещатьс вдоль полого цилиндра кольцеобразному элементу 11. В момент выхода резца из контакта с забоем под действием центробежных сил кольцеобразный элемент 11 отдел етс от резца и обнажает головку следующего kepHa. In the process of the cutter, the abrasive wear of the annular element 10 and the hollow cylinder 6 occurs much faster than the wear of the carbide core. As a result, the core is exposed and then broken or dropped out. After the loss of the core and the annular element 10, it is found that the annular element 11 moves along the hollow cylinder. At the time the tool leaves the contact with the face of the centrifugal force, the ring element 11 separates from the tool and exposes the head of the next kepHa.
Такое выполнение резца позвол ет значительно повысить эффективностьThis embodiment of the cutter can significantly improve the efficiency
разрушени за счет снижени усилий резани , возрастающих перед вскрытием очередного керна.destruction by reducing the cutting effort, increasing before the next core was opened.
