Abstract
Способ комбинированного накатывания резьб, при котором режущий инструмент располагают в зоне образования волны пластически деформируемого металла на высоте, меньшей, чем расстояние от вершины этой волны до обрабатываемой поверхности, отличающийся тем, что формообразование резьбы осуществляется резьбонакатной головкой, содержащей резьбонакатные ролики, между роликами установлены режущие гребенки с зубьями, находящимися напротив выступов накатываемой роликами на заготовке резьбы, при этом ширина вершины зубьев режущих гребенок равна ширине вершины выступов накатываемой роликами на заготовке резьбы, а зубья режущих гребенок расположены таким образом, что их режущие кромки находятся на расстоянии=1,6hот впадины накатываемой роликами на заготовке резьбы, где h- накопленное радиальное обжатие; i - номер текущего витка заборной части резьбонакатного ролика.The method of combined rolling of threads, in which the cutting tool is placed in the zone of wave formation of plastically deformable metal at a height less than the distance from the top of this wave to the work surface, characterized in that the thread is formed by a thread rolling head containing thread rolling rollers, cutting rollers are installed between the rollers combs with teeth opposite the protrusions of the rolling rollers on the thread blank, while the width of the teeth of the cutting combs is equal to and the width of the tops of the protrusions rolled by the rollers on the thread blank, and the teeth of the cutting combs are located so that their cutting edges are at a distance = 1.6h from the hollow of the rollers rolled on the thread blank, where h is the accumulated radial compression; i is the number of the current turn of the intake part of the thread rolling roller.
