Description

Изобретение относитс  к области гидромашиностроени  и может быть использовано при изготовлении рабочих колес гидромашин .The invention relates to the field of hydraulic engineering and can be used in the manufacture of hydraulic impellers.

Известны способы изготовлени  лопастей рабочих колес радиальноосевы.х гидре машин путем формовки плоских листовых заготовок и последуюш,ей обработки послбдних резанием.There are known methods for manufacturing blades of impellers of radially axial hydraulic machines by forming flat sheet blanks and then cutting them after cutting.

Однако в таких способах листовые заготовки вырезают по контуру из листов, толщина которых равна (или больше) максимальной толщине профильной заготовки.However, in such methods, sheet blanks are cut along the contour of sheets whose thickness is equal to (or more) the maximum thickness of the profile blank.

Это снижает коэффициент использовани  листового проката, а также требует последующей сложной механической обработки.This reduces the rate of use of sheet metal, and also requires subsequent complex machining.

Целью изобретени   вл етс  повышение экономичности изготовлени  лопастей.The aim of the invention is to increase the efficiency of manufacturing blades.

Дл  этого по предложенному способу листовую заготовку до обработки резанием сваривают из частей, толщину которых внбирают в соответствип с 3.g;iai:Kon толщпмо профил  лоппсти.To do this, according to the proposed method, the sheet blank is welded from parts, the thickness of which is inserted in accordance with 3.g; iai: Kon, of a loopsti profile, before machining.

На фиг. 1 схематически и:юбражека листова  заготовка, план; ка фиг. 2 - заготовка под лопасть до обработки резанием: на фиг. 3 -- лопасть после обработки резанием .FIG. 1 schematically and: a blank leaflet, plan; ka fig. 2 - blank under the blade before machining: in FIG. 3 - blade after machining.

Заготовка состоит из частей 1 разной толихины, соединенных свариымп швами 2.The blank is made up of parts 1 of different tolichins connected by welds 2.
