Изобретение относитс к металлообработке .The invention relates to metal working.
Известен свободно вращающий многолезвийный резец, лезви которого выполнены в виде многозаходной винтовой линии 1 .Known free rotating multi-blade cutter, the blades of which are made in the form of multiple helix 1.
Недостатком такогь резца вл ютс значительные колебани сил при обработке , обусловленные неравномерным сечением металла, снимаемого лезвием.The disadvantage of such a cutter are significant fluctuations of forces during processing, due to the uneven cross section of the metal removed by the blade.
Цель изобретени - снижение колебаний усилий при обработке.The purpose of the invention is to reduce fluctuations in effort during processing.
Указанна цель достигаетс тем, что резец выполнен с четным количеством винтовых лезвий и каждое четное лезвие срезано на 1/3 его рабочей длины, при этом место среза выполнено по винтовой линии, составл ющей с направлением лезви угол 1C/4.This goal is achieved in that the cutter is made with an even number of screw blades and each even blade is cut to 1/3 of its working length, while the cut point is made along a helix constituting 1C / 4 angle with the blade direction.
На фиг, 1 изображен предлагавши резец с Бырывом; на фиг. 2 - вид А на фиг. 1 (место среза лезви резца}, на фиг, 3 - изменение ширины среза металла при обработке.Fig. 1 shows a cutter with a Byrush; in fig. 2 is a view A of FIG. 1 (cutter blade cut-off point}, fig, 3 - change in the width of the cut metal during processing.
Резец 1, установленный вместе с, осью 2 в державке 3 с возможностью вращени , имеет, например, два лезви 4 и 5, выполненные по винтовой линии. На длине & от нижнего торца лезвие 5 срезано. Длинаfc зависит от конкретных условий обработки и составл ет около 30% от рабочей длины Вр резца. Рабоча длина резца. 2р равна рассто нию, измеренному вдоль оси резца, между крайними точками лезви , участвующими в сн тии припуска металла. Лини среза в месте перехода лезви резца к его удаленной части расположена по винтовой линии и составл ет с направлением лезви угол К/4 (фиг.2). Это необходимо дл постепенного входа лезви резца в работу по сн тию сло металла.The cutter 1, mounted together with the axis 2 rotatably in the holder 3, has, for example, two blades 4 and 5, made along a helix. At length & from the lower end of the blade 5 is cut off. The length fc depends on the specific machining conditions and is about 30% of the working length BP of the tool. The working length of the cutter. 2p is equal to the distance, measured along the axis of the cutter, between the extreme points of the blade involved in the removal of the metal allowance. The cut line at the transition point of the cutter blade to its remote part is located along a helical line and makes the angle K / 4 with the blade direction (Fig. 2). This is necessary for the cutting blade to gradually enter the work on removing the metal layer.
Работа резца происходит следующим образом.The work of the cutter is as follows.
Резец 1 под действием контакта с обрабатываемой деталью и вследThe cutter 1 under the action of contact with the workpiece and after
