Изобретение относитс  к обработке металлов давлением, в частности к способам изготовлени  фитингов.The invention relates to the processing of metals by pressure, in particular to methods for producing fittings.

Известны способы изготовлени  заготовок отводов, включающие вырезку криволинейной по контуру плоской лисГОБОЙ заготовки и последующую их формовку в штампе.There are known methods for manufacturing precursors for bends, including cutting curved along the contour of a flat or preformed billet and their subsequent forming into a stamp.

Цель изобретени  - уменьшение разнотолщинности стенок отводов.The purpose of the invention is to reduce the thickness of the walls of the bends.

Дл  этого плоские заготовки вырезают по контуру с кривизной, меньшей кривизны средней линии отвода, а затем полученные заготовки собирают в пакет и гнут на ребро до окончательных размеров заготовки отвода.To do this, flat blanks are cut along a contour with a curvature less than the curvature of the center line of the bend, and then the resulting blanks are collected in a bag and bent on the edge to the final dimensions of the bend workpiece.

На фиг. 1 показана заготовка после гибки на ребро (условными лини ми показана ее исходна  форма); на фиг. 2 - отштампованна  половинка отвода.FIG. 1 shows the workpiece after bending on the edge (conditional lines show its original shape); in fig. 2 - stamped half outlet.

Предлагаемый способ осуществл етс  следующим образом.The proposed method is carried out as follows.

Из листа или полосы вырезают плоские заготовки с криволинейным контуром, радиус кривизны которых меньше радиуса кривизны готового отвода. Вырезанные заготовки собирают в пакет и гнут в штампе на ребро до кривизны средней линии отвода. Полученные таким образом заготовки 1 формуют в штампе ,в половинки отводов 2.Flat pieces with a curvilinear contour, the radius of curvature of which is less than the radius of curvature of the finished elbow, are cut from a sheet or strip. Cut out the workpiece is collected in the package and bend in the stamp on the edge to the curvature of the center line of the outlet. Thus obtained blanks 1 are molded in a stamp, into halves of taps 2.

Предмет изобретени Subject invention

Способ получени  заготовок отводов, при котором производ т вырезку листовой заготовки и формовку ее в штампе, отличающийс  тем, что, с целью уменьшени  разнотолщинности стенок отводов, плоские заготовки вырезают по контуру с кривизной, меньшей кривизны средней линии отвода, а затем полученные заготовки собирают в пакет и гнут на ребро до окончательных размеров заготовки отвода.A method of producing precursors in which a sheet is cut and molded into a die, characterized in that, in order to reduce the irregularities in the walls of the bends, flat blanks are cut along the contour with a curvature less than the curvature of the center line of the outlet, and then package and bend on the edge to the final size of the workpiece tap.
