Abstract
Изобретение относитс к обработке металлов давлением и может быть использовано дл местного деформировани стенки полой детали. Цель изобретени - повышение качества обрабатываемых деталей путем правки их стенки в зоне деформировани . С корпусом 1 жестко св зана оправка 2 с фиксирующей частью дл установки детали. Рычаги 5 снабжены профильными калибрующими участками на поверхност х, несущих пуансоны 6 и матрицы 7. Центр оси 4 каждой пары рычагов 5 удален от оси симметрии штампа на рассто ние, не превышающее рассто ни в плане от соответствующего участка рабочей поверхности фиксирующей части оправки 2 до оси симметрии штампа. На корпусе 1 коаксиально фиксирующей части оправки 2 расположен съемник 3 готового издели , выполненный со сквозными радиальными пазами на рабочей поверхности и установленный с возможностью осевого перемещени . Узел поворота рычагов 5 выполнен в виде центрального 12 и периферийных 13 клиньев, установленных с возможностью осевого перемещени и взаимодействи с рычагами 5. В конце рабочего хода калибрующей частью рычагов 5 осуществл етс правка стенки готового издели с внутренней и наружной сторон в зоне деформировани 1 з. п ф-лы, 5 ил. (С (ЛThe invention relates to the processing of metals by pressure and can be used for local deformation of the wall of a hollow part. The purpose of the invention is to improve the quality of machined parts by straightening their walls in the deformed zone. A frame 2 is rigidly connected with a mandrel 2 with a fixing part for mounting the part. The levers 5 are provided with core calibrating areas on surfaces carrying punches 6 and dies 7. The center 4 axis of each pair of levers 5 is removed from the axis of symmetry of the stamp for a distance not exceeding the distance in plan from the corresponding section of the working surface of the fixing part of the mandrel 2 to the axis symmetry stamp. On the housing 1 of the coaxially fixing part of the mandrel 2 there is a puller 3 of the finished product, made with through radial grooves on the working surface and mounted with the possibility of axial movement. The knot of rotation of the levers 5 is made in the form of a central 12 and peripheral 13 wedges installed with the possibility of axial movement and interaction with the levers 5. At the end of the stroke, the calibrating part of the levers 5 corrects the wall of the finished product from the inner and outer sides in the deformation zone 1 h. p f-ly, 5 ill. (C (L
