Изобретение относитс  к обработке металлов давлением, а именно к способам обработки листовых заготовок с получением полых Выступов на них.The invention relates to the processing of metals by pressure, and in particular to methods of processing sheet blanks to produce hollow protrusions on them.

Известен способ получени  полого выступа на листовой заготовке, включающий отбортовку прошивкой с выдавливание.м материала заготовки из-под прошивного пуансона в боковую стенку получаемого выступа 1.A known method of obtaining a hollow protrusion on a sheet blank, comprising flashing the firmware with the extrusion of the material of the workpiece from under the piercing punch into the side wall of the resulting protrusion 1.

Недостаток известного способа состоит в невысоком качестве получаемых изделий за счет большой разностенностл выступа.The disadvantage of this method consists in the low quality of the products obtained due to the large variability of the protrusion.

Целью изобретени   вл етс  повышение качества получае.мых изделий.The aim of the invention is to improve the quality of the obtained products.

Это достигаетс  тем, что предварительно на поверхности заготовки со стороны, противоположной будущему выступу, формируют вспученность на участке полости выступа и тороидальное углубление на участке боковой стенки выступа.This is achieved by the fact that, on the surface of the preform, on the side opposite to the future protrusion, an exfoliation is formed in the portion of the projection cavity and a toroidal recess in the portion of the sidewall of the protrusion.

На чертеже показана схема осуществлени  способа.The drawing shows a scheme for implementing the method.

Способ получени  полого выступа осуществл ют следующим образом.The method for producing a hollow protrusion is carried out as follows.

На поверхности заготовки 1 со стороны, противоположной будущему выступу 2, формируют вспученность на участке полости выступа и тороидальное углубление 3 на участке боковой стенки выступа 2. Затем производ т отбортовку прошивкой с выдавливанием материала 4 заготовки 1 из-под прошивного пуансона 5 в боковую стенку получаемого выступа 2.On the surface of the workpiece 1 from the side opposite to the future protrusion 2, an expansion is formed in the portion of the protrusion cavity and a toroidal recess 3 in the portion of the side wall of the protrusion 2. Then flared by extrusion of material 4 of the blank 1 from the piercing punch 5 into the side wall of the resulting protrusion 2.

Причем дл  обеспечени  противодавлени  при образовании боковой стенки выступа заготовку 1 помещают на твердую плиту 6 с прокладкой 7 из эластичного .материала .Moreover, in order to provide counterpressure during the formation of the side wall of the protrusion, the workpiece 1 is placed on a solid plate 6 with a gasket 7 of elastic material.

Использование предлагаемого способа обеспечивает повышение качества получаемых изделий за счет устранени  разностенности в выступе издели .The use of the proposed method improves the quality of the products obtained by eliminating the difference in the thickness in the protrusion of the product.
