Abstract
Изобретение относитс к металлообработке, а именно к изготовлению ребристых трубчатых радиаторов. Цель изобретени - снижение металлоемкости трубчатых радиаторов за счет увеличени высоты и количества ребер при одновременном уменьшении толщины ребер. Инструмент дл получени ребристых трубчатых радиаторов имеет вид сегмента 1 трубчатой формы с базовой цилиндрической частью 2, крепежными отверсти ми 3 и режущей частью, режуща кромка 4 которой получена пересечением задней рабочей поверхности 5 и передней рабочей поверхности 6. Задн поверхность 5 образована конической поверхностью 7, а передн поверхность 6 - конической винтовой поверхностью 8, /косым геликоидом/ соосной конической поверхности 7. Режуща кромка 4, образованна пересечением двух конических поверхностей 7 и 8, одна из которых винтова , будет иметь форму винтовой линии на конической поверхности 7 с шагом, несколько превышающим шаг винтовой поверхности 8, а следовательно, и шаг необходимого оребрени , дл которого предназначен инструмент. Выполнение рабочих поверхностей в виде конических, передн из которых имеет винтовую форму, позвол ет достичь в инструменте максимальных передних углов, одинаковых во всех сечени х режущей кромки, что вл етс важным фактором дл достижени минимальных сил резани и усадки подрезаемых слоев. 4 ил.The invention relates to metal working, in particular to the manufacture of ribbed tubular radiators. The purpose of the invention is to reduce the metal intensity of tubular radiators by increasing the height and number of ribs while reducing the thickness of the ribs. The tool for producing finned tubular radiators has the shape of a tubular segment 1 with a basic cylindrical part 2, mounting holes 3 and a cutting part, the cutting edge 4 of which is obtained by intersecting the rear working surface 5 and the front working surface 6. and the front surface 6 is a conical screw surface 8, / oblique helicoid / coaxial conical surface 7. The cutting edge 4 formed by the intersection of two conical surfaces 7 and 8, one of which Screws will have the shape of a helix on a conical surface 7 with a pitch slightly exceeding the pitch of the screw surface 8, and hence the pitch of the required finning for which the tool is intended. Making the working surfaces in the form of conical, the front of which has a screw shape, allows the tool to reach maximum rake angles that are the same across all cutting edge sections, which is an important factor for achieving minimum cutting forces and shrinking of the layers being cut. 4 il.
