Description

Изобретение относится к металлообработке и может быть использовано при фрезеровании труднообрабатываемых материалов. сThe invention relates to metalworking and can be used when milling difficult to process materials. from

По основному авт.св. №376997 известна торцовая фреза с круглыми самовращающимися резцами, расположенными в параллельных оси фрезы пазах так, что оси вращения резцов расположены перпендикулярно оси вращения фрезы. Фреза предназначена для обработки преимущественно жаропрочных сплавов.By main auto No. 376997 known face milling cutter with round self-rotating cutters located in grooves parallel to the cutter axis so that the axis of rotation of the cutters are perpendicular to the axis of rotation of the cutter. The milling cutter is intended for processing mainly heat-resistant alloys.

Недостаток известной конструкции . торцовой фрезы заключается в том, 15 что при работе срезанная стружка налипает на резец и увлекается в паз корпуса. Паз забивается, и работа фрезы становится невозможной, так как резец заклинивается стружкой, 20 вращение его прекращается.The disadvantage of the known design. end milling cutter is 15 that during operation the cut chips stick to the cutter and carried away in the groove of the body. The groove is clogged, and the operation of the cutter becomes impossible, since the cutter is jammed with chips, 20 its rotation stops.

Цель изобретения - очищение режущей кромки от стружки.The purpose of the invention is the cleaning of the cutting edge of the chips.

Поставленная цель достигается . 25 тем, что в торцовой фрезе' на боковой цилиндрической поверхности корпуса выполнена кольцевая проточка, где свободно установлено очистное кольцо, лежащее своим нижним торцом 30 на режущих кромках самовращающихся резцов.The goal is achieved. 25 by the fact that in the face mill 'on the side cylindrical surface of the body an annular groove is made, where a cleaning ring is freely installed, lying with its lower end 30 on the cutting edges of the self-rotating cutters.

На фиг. 1 изображена описываемая торцовая фреза, общий вид; на фиг. 2 - вид А на фиг. 1 с частичным .вырывом.In FIG. 1 shows the described face mill, General view; in FIG. 2 is a view A in FIG. 1 with a partial breakout.

В пазах корпуса 1 фрезы на упорном 2 и радиальном 3 подшипниках скольжения н.а осях 4 установлены роторные резцы 5. Очистное кольцо 6 свободно лежит на режущих кромках резцов в кольцевой канавке 7 корпуса.In the grooves of the mill body 1 on the thrust 2 and radial 3 sliding bearings on the axes 4 are installed rotary cutters 5. The cleaning ring 6 freely lies on the cutting edges of the cutters in the annular groove 7 of the housing.

При работе описываемой фрезой срезанная стружка, налипшая на резец 5, увлекается в паз корпуса 1 фрезы, встречает на своем пути очистное кольцо 6, в результате чего стружка отделяется от резца и не попадает в паз корпуса. Это позволит исключить забивание паза стружкой и заклинивание резца.During the operation described by the cutter, the cut chip adhering to the cutter 5 is entrained in the groove of the mill body 1, encounters a cleaning ring 6 on its way, as a result of which the chip is separated from the cutter and does not fall into the groove of the body. This will eliminate the clogging of the groove with chips and jamming of the cutter.

Claims

This invention relates to metalworking and can be used in milling difficult-to-machine materials. According to the main auth. No. 376997 of a known face milling cutter with round self-turning cutters arranged parallel to the milling cutter axis so that the rotational axes of the cutters are perpendicular to the rotation axis of the milling cutter. The milling cutter is designed to process predominantly heat resistant alloys. A disadvantage of the known design of the end mill is that, during operation, the cut chips adhere to the cutter and are carried into the groove of the body. The groove is clogged and the cutter becomes impossible because the cutter is wedged. The chip rotation stops. The purpose of the invention is to clean the cutting edge from chips. This goal is achieved by the fact that an annular groove is made in the face mill on the lateral cylindrical surface of the building, where a cleaning ring is freely installed, which lies with its lower end on the cutting edges of the self-rotating cutters. FIG. 1 shows the described face milling cutter, general view; in fig. 2 is a view A of FIG. 1 with partial digging. In the slots of the cutter body 1 on the thrust 2 and radial 3 sliding bearings, and axles x 4, rotary cutters 5 are installed. The cleaning ring 6 lies freely on the cutting edges of the cutters in the annular groove 7 of the body. During operation of the cutter described, the cut chips adhered to the cutter 5, is carried into the groove of the cutter body 1, encounters a cleaning ring b in its path, with the result that the chips separate from the cutter and do not fall into the body groove. This will prevent blocking of the groove by chips and jamming of the tool. The invention of Tortsov cutter auth.St. No. 376997, characterized in that, in order to clean the cutting edge of

shavings, on the lateral cylindrical surface of the body there is a ring-shaped groove, in which

a Kojiiiiio clearing was installed, which lies with its lower end on the edges of the self-rotating repets.
