Description
После выполнени на наружной поверхности соедин емой трубы 3 выступов 4 или 7, а на внутренней поверхности ответной детали 1 соответствующих впадин 2 или 8 ввод т трубу 3 в отверстие ответной детали 1, располага выступы 4 или 7 против впадин 2 или 8. Затем трубы 3 равномерно пластически деформируют изнутри с усилием и выдержкой, обеспечивающими заполнение впадин 2 и 8 материалом выступов 4 и 7, объем которых выбирают из условий создани требуемого внутреннего напр жени в соединении.After making 3 protrusions 4 or 7 on the outer surface of the pipe to be joined, and on the inner surface of the counterpart 1 of the corresponding depressions 2 or 8, the pipe 3 is inserted into the opening of the counterpart 1, protrusions 4 or 7 against the depressions 2 or 8 are placed. Then the pipes 3 they plastically uniformly deform from the inside with force and hold, ensuring the filling of depressions 2 and 8 with material of projections 4 and 7, the volume of which is chosen from the conditions for creating the required internal voltage in the joint.
При ликвидации первоначального зазора А выступы 4 и 7 точками Ь и с касаютс основани ВС впадин 2 и 8. При дальнейшем давлении в случае выполнени впадин в виде «ласточкиного хвоста происходит распр млени дуги be и плавное постепенное затекание металла выступа 4 в угловые точки В и С. Дл устранени возможности повреждени поверхности основани впадины 2 вершины точки b и точки с выступа 4 скруглены. При выполнении впадины 8 в виде «бочки пр моугольный профиль выступа 7 при дальнейшем давлении принимает также бочкообразный профиль. В случае получени соединений элементов различной твердости материал деталей , имеющих впадины с поднутрением, например , в виде «ласточкиного хвоста, «бочки и т. д. долйсен быть с большей твердостью, чем твердость материала детали, имеющей ответные выступы.When the original gap A is eliminated, the protrusions 4 and 7 of the points b and c touch the base of the sun of the valleys 2 and 8. With further pressure, if the hollows are made in the form of a dovetail, the arc of the arc will smooth and the gradual flowing of the metal of the protrusion 4 to the corner points B and C. To eliminate the possibility of damage to the base surface of the valley 2, the vertices of point b and the point from protrusion 4 are rounded. When performing the depression 8 in the form of a “barrel, the rectangular profile of the protrusion 7 with a further pressure also receives the barrel-shaped profile. In the case of obtaining compounds of elements of different hardness, the material of parts that have depressions with undercuts, for example, in the form of a "dovetail", "barrels, etc., should be with greater hardness than the hardness of the material of the part having counter-tabs.
