摘要： The invention relates to a method for the production of steel balls (14) which are particularly used as shot pellets, by forming a blank (5) in a flat or round bar molding tool (1 or 6). In order to achieve economical production, a plurality of shot pellets (14) are produced simultaneously from said rod-shaped blank (5) by separating an intermediate rod piece (16) in-between adjacent steel balls (14).

摘要： Изобретение относится к изготовлению металлоизделий шарообразно формы. Способ заключается в том, что производят сквозной нагрев круглых заготовок соответствующего размера в среднечастотном индукционном устройстве, прокатку из них шаров на стане поперечно-винтовой прокатки при температуре 950-1070°C, подстуживание шаров до 620-700°C в подстуживающем барабане с принудительным воздушным охлаждением, поверхностный нагрев шаров до 850-930°C в высокочастотном индукционном устройстве, содержащем вращающуюся транспортировочную трубку и несколько секций индукторов, закалку шаров до температуры 125-160°C в закалочном барабане с охлаждением проточной водой и самоотпуск шаров в контейнерах. Способ позволяет повысить износостойкость и ударную стойкость металлических шаров в случае их изготовления из низколегированных сталей с возможностью уменьшения массовой доли углерода применяемой стали.

摘要： A machine, method and tooling to precision cold form roller blanks for anti-friction bearings. The machine is a multistage progressi former using floating die cavities to enable simultaneous shaping of the ends of the roller 10 with high accuracy and without flash. tools and staged forming create an improved roller with an advantageous grain pattern and devoid of structural defects previously attributable to the presence of sheared end face material in the radiused corners 101 of the blank and flash at its mid-section.

摘要： The invention relates to a device for shaping spherical objects from sections of lines consisting of a dimensionally stable, non-elastic material, e.g. metal foils, said lines having evenly distributed cuts and having been combined into a strand. The shaping device has a stationary part (27) and a part which moves in relation to said stationary part at a constant mutual distance (28) therefrom. Both parts have profiled grooves (29, 30) in the surfaces facing towards each other, said grooves lying with their open sides opposite each other, extending in the direction of the relative movement and having inner surfaces with high friction coefficients.
