Description

Предметом изобретени   вл етс  гибочно-выт жной штамп с жестким зажимом заготовки при помощи гидравлических плунжеров.The subject of the invention is a bending-die with a rigid clamping of the workpiece with the help of hydraulic plungers.

При штамповке деталей с неглубокой выт жкой дл  предотвращени  образовани  гофров на кра х заготовки последние знЬкимаютс  и по мере выт жки под действием возникающего усили  продвигают1с  между штампами. При этом в местах выт жки кромку заготовки ут гивает, как показано на фиг. 1, что вызывает дальнейшую обрезку кромок (фиг. 2) и неизбежную с этим потерю металла.When stamping parts with a shallow extrusion to prevent the formation of corrugations at the edges of the workpiece, the latter are known and, as they are drawn out, under the action of the force produced, they advance between the dies. At the same time, in places of stretching, the edge of the workpiece becomes thinner, as shown in FIG. 1, which causes further trimming of the edges (FIG. 2) and the inevitable loss of metal.

В предлагаемом гибочно-выт жном штампе применен жесткий зажим заготовки по контуру, исключающий проскальзывание ее кромок, и процесс выт жки производитс  только за счет местного уплотнени  металла . Дл  некоторых видов производства, в частно сти крышки люка Железнодорожной гондолы, такой процесс позвол ет сэкономить значительное количество металла.In the proposed bending-extrusion die, a rigid clamp of the workpiece along the contour is used, which prevents its edges from slipping, and the drawing process is carried out only by local sealing of the metal. For some types of production, such as the hatch cover of the Railway gondola, this process saves a significant amount of metal.

Штамп дл  штамповки этой детали изображен на фигуре 3.A stamp for stamping this part is depicted in Figure 3.

Зажим краев заготовки осуществл етс  при помощи двух р дов гидравлических плунжеров / через прокладку 2. Действие зажима происходит после перехода движени  траверсы пресса на рабочее давление перед началом выт жки гофр.The edges of the workpiece are clamped by means of two rows of hydraulic plungers / through the gasket 2. The clamping action takes place after the movement of the crosshead of the press to working pressure starts before the corrugation begins.
