Изобретение относитс  к области обра.ботки металлов давлением, в частности к инструменту дл  выт жки пр моугольных в плане изделий.The invention relates to the field of metal pressure treatment, in particular, to a tool for drawing rectangular products.

Известны нуансоны дл  выт жки из листовой заготовки пр моугольных в плане изделий , имеющие округленные кромки в местах сопр жени  боковых граией между собой и боковых граней с торцом и сферические участки в местах сопр жени  двух боковых граней с торцом.Nuansons are known for drawing from rectangular-shaped products from sheet blank, having rounded edges at the points of mating between the side faces between themselves and the side faces with the end, and spherical areas at the points of mating between the two side faces and the ends.

Дл  обеспечени  изготовлени  за один переход пр моугольных коробок с соотношением высоты к ширине 0,8 и с минимальными радиусами сопр жени  боковых стенок между собой и боковых стенок с дном, доход щими до одной толщины материала заготовки, в нредлагаемом пуансоне радиус сферы в месте сопр жени  двух боковых граней с торцом выбран из расчета не менее н ти радиусов сонр жени  боковых граней между собой и боковых граней с торцом, которые соответствуют радиусам на готовом изделии.To ensure production in one transition, rectangular boxes with a height-to-width ratio of 0.8 and with minimum radius of coupling of the side walls between themselves and the side walls with the bottom, reaching up to one thickness of the material of the workpiece, in the proposed punch the radius of the sphere at the interface two side faces with an end face are selected on the basis of not less than the same radii of side edges between each other and side faces with an end face that correspond to the radii on the finished product.

На фиг. 1 иоказан описываемый нуансон, вид сбоку и в плане; иа фиг. 2 - готовое изделие , вид в плане с разрезом по А-А, где Г1 - радиус сопр жени  боковых стеиок иа изделии; rz - радиус сопр жени  боковых стенок с дном издели  на пр мых участках; Гз - радиус сферы в месте сопр жени  двухFIG. 1 and shows the described nuanson, side view and in the plan; FIG. 2 is a finished product, a plan view with a section along A-A, where G1 is the radius of conjugation of the side steakes of the product; rz is the interface radius of the side walls with the bottom of the product on straight sections; Gz is the radius of the sphere at the junction of two

боковых стенок с дном; 5 - толш;ина материала заготовки; Я - высота издели ; В - ширина стенки издели .side walls with bottom; 5 - thickness; ina material of the workpiece; I - the height of the product; B is the width of the wall of the product.

В предложенном пуансоне радиусы сопр жени  боковых граней между собой и боковых граней с торцом ri 1-2 S готового нздели , а радиус сферы сопр жени  двух боковых граней с торцом равен .In the proposed punch, the interface radii of the side faces between each other and the side edges with the end face ri 1-2 S of the finished joint, and the radius of the interface sphere of the two side faces with the end face is equal.

Наличие большого радиуса сонр жени  в углах пуансона приводит к уменьшению концентрации напр жений в опасном сечении.The presence of a large sonar radius at the corners of the punch leads to a decrease in the concentration of stresses in a dangerous section.

С уменьшением радиуса сопр жени  стенок увеличиваетс  периметр коробки и, следовательно , увеличиваетс  несуща  способность опасного сечени  и достижима  высота выт гиваемой коробки.With a decrease in the interface radius of the walls, the perimeter of the box increases and, consequently, the carrying capacity of the dangerous section increases and the height of the drawable box is achievable.

Така  конструкци  пуансона позвол ет выт гивать за один переход высокие коробки с отношением высоты коробки к ее ширине не менее 0,8 с малыми угловыми и донными закруглени ми иа пр мых участках.Such a punch design allows drawing out high boxes in a single transition with a ratio of the height of the box to its width of at least 0.8 with small angular and bottom curvature and straight sections.
