Description
(54) СПОСОБ ФОРМИРОВАНИЯ РЕЗЬБЫ НА ДЕТАЛЯХ(54) METHOD OF FORMING THREADS ON DETAILS
среднему диаметру выправл ет несколько расплющенную вершину ее профил и приводит размеры резьбы в соответствй с ГОСТом, так как образующа с вогнутость 2 значительно меньше глубины Г 1 складки и вполне укладываетс в допуски, оговоренные ГрСТом.the average diameter straightens the somewhat flattened top of its profile and gives the thread dimensions in accordance with GOST, since the concavity 2 forming the concavity 2 is significantly less than the depth G 1 of the fold and fits perfectly within the tolerances specified by GrSt.
П р,и м е р. Внутреннюю резьбу в стальной гайке М 10x1,5 кл. 6 Н формируют гаечным выдавливающим метчиком с открытым контуром резьбы. Сформированна заборной и калибрующей част ми метчика резьба детали об зательно имеет складку на вершине. Глубина этой складки дл резьбы Ml0x1,5, в зависимости от размеров отверсти и условий обработки, колеблетс в пределах 0,1-0,35 мм. Наплывы металла, образуюашё складку, зачастую выход т за пределы допуска на внутренний диаметр резьбы, размер которого в соответствии с ГОСТом 16093-70 составл ет 8,376± мм.PRI and meer. Female thread in steel nut M 10x1.5 cl. 6 N form a nut pressing with open thread contour. The thread of the part formed by the intake and calibrating parts of the tap necessarily has a crease at the top. The depth of this fold for the thread Ml0x1.5, depending on the size of the hole and the processing conditions, ranges from 0.1-0.35 mm. The sagging of the metal forming the fold often goes beyond the tolerance for the internal diameter of the thread, the size of which in accordance with GOST 16093-70 is 8.376 ± mm.
Гайка при дальнейшем продвижении по резьбовой части метчика попадает на его гладкий цилиндрический по сок, который раздает внутренний диаметр резьбы до размера 0 8,670-0,03 мм. При этом при расплющивании резьбовогсUpon further advance along the threaded part of the tap, the nut falls on its smooth cylindrical juice, which distributes the internal diameter of the thread to a size of 0 8.670-0.03 mm. At the same time when flattening thread
профил кратер на вершине резьбы заполн етс металлом.The crater profile at the top of the thread is filled with metal.
Перемеща сь далее по метчику, гай ка проходит по его резьбовому участку - производитс повторна (окончательна ) калибровка резьбы по профилю .Moving further along the tap, the nut passes through its threaded section — the thread is calibrated over the profile (final).
Данным способом можно получить точную по всем размерам резьбу, ликвидировать складку на вершине профил , расширив при этом допуск на изЬотовление отверсти под резьбу М 10x1 с 9,,07 мм до 9,,17 мм.This method can be used to obtain exact threads in all sizes, to eliminate the fold at the top of the profile, while expanding the tolerance for creating holes for the thread M 10x1 from 9, 07 mm to 9,, 17 mm.
