Description

тельно при этом производ т осадку, получа кольцевую деталь.In this case, the precipitate is produced to obtain an annular part.

По предлагаемому способу из полосы шириной 40 мм и толщиной 3 мм вырубали заготовку (мпогограииую шайбу, изображенную на фиг. 1) с наружным диаметром 45 мм и пробивали в ней отверстие диаметром 20 мм. Далее полуфабрикат изгибали относительно окружности, наход ш,ейс в плоскости полуфабриката между ее контурами , образованными при вырубке и пробивке. В данном случае изгибали относительно среднего диаметра под углом 120°. Далее полуфабрикат выпр мл ли и при этом дополнительно производили осадку . Наружный диаметр готовой кольцевой детали составил 42 мм, диаметр отверсти 24 мм. Коэффициент использовани металла при осуществлении предлагаемого способа получени кольцевых деталей составл ет 0,6. Эффект от внедрени заключаетс в том, что форма полуфабриката после ее гибки позвол ет в широких пределах варьировать размеры готовых кольцевых деталей.According to the proposed method, a blank was cut from a strip 40 mm wide and 3 mm thick (the mechanical washer shown in Fig. 1) with an outer diameter of 45 mm and punched a hole with a diameter of 20 mm in it. Then, the semi-finished product was bent relative to the circumference, which was located in the plane of the semi-finished product between its contours formed during cutting and punching. In this case, bent relative to the average diameter at an angle of 120 °. Next, the semi-finished product was rectified, and in addition, a precipitate was produced. The outer diameter of the finished ring part was 42 mm, the diameter of the hole was 24 mm. The utilization of the metal in the implementation of the proposed method of obtaining ring parts is 0.6. The effect of the introduction is that the shape of the semi-finished product after its bending allows the dimensions of the finished ring parts to be varied over a wide range.

Claims

1. A method for producing an annular part from a flat sheet blank, in which a hole is punched in the blank, deforms the semi-finished product and gives it the shape of a ring with a broken or curvilinear generatrix, and then is straightened, which is hampered by the reduction in material consumption by ensuring that annular parts of various sizes are obtained from blanks of the same size, before being deformed from a flat blank, cutting is done, and deformation is carried out by bending sections lying on both sides of the circumference between the contours formed during cutting and punching relative to it, and in the course of straightening, an additional precipitate is produced.

2. A method according to claim 1, characterized in that the semi-finished product is bent at an angle of 100-150 °.
