(54) СПОСОБ ЛОМКИ ПРОКАТА(54) METHOD FOR REMOVING A ROLL
II
Изобретение относитс к обработке метаппов аавпением и может быть испопьдовано в машиностроении цп разцеп ени проката.The invention relates to the processing of metafields and the application and can be used in the engineering industry of rolling stock hire.
Известен способ помки проката, включающий нанесение на прокат концентратора напр жений и приложение к нему раст гивающей и изгибающей нагрузок There is a known method for rolling a rolling stock, which includes applying a stress concentrator to a rolled product and applying tensile and bending loads to it.
Недостатком известного способа. вп етс низкое качество торцов получаемых заготовок.The disadvantage of this method. Low quality ends are received.
Цель изобретени - повышение качества торцов.The purpose of the invention is to improve the quality of the ends.
Поставленна цель аостигаетс тем, что согласно способу ломки проката, включающем нанесение на прокат концентратора и приложение к нему раст гивающей и изгибающей нагрузок, раст гивающую нагрузку приклацывают к прокату лереа приложением изгибающей нагрузки.The goal is achieved by the fact that, according to the method of breaking a rolled product, which involves putting a concentrator on a rolled product and applying tensile and bending loads to it, the tensile load is applied to the rolled steel by applying a bending load.
Раст гивающую нагрузку созйают путем фиксации проката по обе стороны относительно плоскости концентратораThe tensile load is assembled by fixing the rolling on both sides relative to the hub plane.
напр н ений и последующего его охлаждени .voltages and its subsequent cooling.
; Дл увеличени - деформации проката его перед фиксацией подогревают.; To increase - the deformation of the rolled it is heated before fixation.
Пример. Осуществл етс раскрой стали 45 и стали У8 диаметром 35 мм с сегментным надрезом глубиной 1.5 мм. Прокат зажимают по обе стороны от надркза на рассто нии ЗО мм усилием 8От, после чего охлаждают участок между зажимами до 80° С и изгибают прокат в плоскости надреза. Прокат хрупко разрушаетс . В обоих случа х качество торцов заготовок выше качества торцов заготовок полученных известным способом . Величина макронеровностей поверхности излома не превышает 2 мм дл с стали 45 и 1,5 мм ол стали У8.Example. Cutting of steel 45 and steel U8 with a diameter of 35 mm with a segmental notch 1.5 mm deep is carried out. Rolling is clamped on both sides of the supernatant at a distance of 30 mm from the EO with a force of 8F, after which the section between the clamps is cooled to 80 ° C and the rolling in the notch plane is bent. The rental is fragile. In both cases, the quality of the ends of the blanks is higher than the quality of the ends of the blanks obtained in a known manner. The size of the macroroughness of the fracture surface does not exceed 2 mm for steel 45 and 1.5 mm ol U8 steel.
