Description
Резервуары дл хранени бензина и нефти под давлением стро тс в насто щее врем каплевидными. Оболочка корпуса и днища таких резервуаров собираетс из частей / (фиг. 1) листового проката, которым придаетс двойна кривизна в со ответствии с их взаи,мным расположением в сборке.Tanks for storing gasoline and oil under pressure are currently being droplet shaped. The shell of the hull and the bottom of such tanks is assembled from parts / (Fig. 1) of sheet metal, which is given a double curvature in accordance with their mutual arrangement in the assembly.
Согласно изобретению предлагаетс изготовл ть эти части холодной Штамповкой на щтампе, изображенном на фиг- 2, 3, 4 и 5.According to the invention, it is proposed to manufacture these parts by cold stamping on the chip shown in Figures 2, 3, 4 and 5.
Продольный профиль ручь матрицы 2 этого штампа (фиг. 2) соответствует кривой меридиального сечени оболочки. В поперечном сечении ручей матрицы 2 (фиг. 4) имеет многогранный контур с одним числом граней по всей длине, ширина которого имеет одну и ту же кратность с шириной изготовл емой части оболочки. Пуансон 3 имеет в сеченли то же очертание, что и ручей матрицы 2. Дл фиксаци1и начального и пОСледуюшего положени штампуемой заготовки стол штампа со стороны узких его сторон снабжен направл ющими дугами 4 VL 5, имеющими радиальные пазы.The longitudinal profile of the stream of the matrix 2 of this stamp (Fig. 2) corresponds to the curve of the meridian section of the shell. In cross section, the brook of matrix 2 (Fig. 4) has a multi-faceted contour with one number of faces along the entire length, the width of which has the same multiplicity with the width of the manufactured part of the shell. The punch 3 has the same outline in the section as the creek of the matrix 2. To fix the initial and next position of the forged workpiece, the punch table from the narrow sides of it is provided with guide arcs 4 VL 5 having radial grooves.
Заготовка 7 с держател ми 6 ук .ладываетс на матрицу 2 в среднееWorkpiece 7 with holders 6 in. Fits on matrix 2 into average
положение и обжимаетс пуансоном 3 (фиг. 4). После подъема пуансона 3 заготовка 7 перемещаетс на одно деление дуг и вторично обжимаетс (фиг. 5). Один из перегибов первого обжима совпадает с перегибом второго обжима, чем и обеспеч1иваетс взаимное угловое расположение перегибов. Полное изготовление детали.осуществл етс за несколько обжвмов, при этом число обжимов зависит от кривизны части / в поперечном сечении.the position and is compressed by the punch 3 (Fig. 4). After lifting the punch 3, the workpiece 7 is moved one arc division and is again crimped (Fig. 5). One of the bends of the first crimp coincides with the bend of the second crimp, which ensures the mutual angular arrangement of the bends. The complete fabrication of the part is carried out in several sections, and the number of crimps depends on the curvature of the part / in cross section.
