Claims (1)

Способ изготовления полуфабрикатов лезвий ножей, при котором заготовку ножа получают прокаткой в калиброванных секторных валках с нагревом и рубкой в штампе, отличающийся тем, что перед рубкой назначают размеры заготовки лезвия ножа, исходя из условия превышения в 1,5 раза заданной шириной готового лезвия в зоне перехода к ручке ножа ширины его заготовки, а ширину лезвия в основании острия ножа назначают в зависимости от степени деформации в поперечном направлении и определяют исходя из равенства объемов перемещаемого металла заготовки и готового лезвия, при этом нагрев полученной заготовки осуществляют после рубки, а прокатку проводят перпендикулярно направлению деформации до получения режущей кромки на лезвии ножа с минимальными припусками под финишные операции механической обработки и с заданной твердостью.A method of manufacturing semi-finished knife blades, in which the knife blank is obtained by rolling in calibrated sector rolls with heating and cutting in a stamp, characterized in that the dimensions of the knife blade blank are assigned before cutting, based on the condition that the finished blade is 1.5 times larger than the specified width of the finished blade in the zone the transition to the handle of the knife, the width of its workpiece, and the width of the blade at the base of the knife tip is assigned depending on the degree of deformation in the transverse direction and is determined based on the equality of the volumes of the moved metal of the workpiece and the finished blade, while heating the obtained workpiece is carried out after cutting, and rolling is carried out perpendicular to the direction of deformation to obtain a cutting edge on the blade of the knife with minimal allowances for finishing machining operations and with a given hardness.
