Abstract
Изобретение относитс к обработке металлов давлением, в частности к способам изготовлени многогранных крепежных деталей. Цель изобретени - повышение качества получаемых деталей и снижение энергозатрат процесса. Прутковую цилиндрическую заготовку предварительно осаживают до диаметра, равного диаметру окружности, вписанной по касательной к выемкам детали, которую получают штамповкой осаженной заготовки. Выемки формируют на участках шириной, равной 70...80 % прот женности грани. После штамповки на полученном полуфабрикате обрубают заусенец, прошивают отверстие и нарезают резьбу соответствующего размера. 2 з.п. ф-лы, 5 ил.The invention relates to the processing of metals by pressure, in particular, to methods for producing multifaceted fasteners. The purpose of the invention is to improve the quality of the parts and reduce the energy consumption of the process. Rod cylindrical billet pre-upset to a diameter equal to the diameter of a circle inscribed tangentially to the grooves of the part, which is obtained by stamping the upset billet. The notches are formed in areas with a width equal to 70 ... 80% of the face length. After punching on the obtained semi-finished product, a burr is chopped off, a hole is stitched and a thread of the appropriate size is cut. 2 hp f-ly, 5 ill.
