Abstract
Patente de Invenção: "MéTODO E DISPOSITIVO PARA TRANSFORMAçãO DE METAIS". Em um método para trabalhar uma peça de metal por meio de recalque em um dispositivo de recalque que contém um dispositivo de aperto, uma matriz e um martelo de recalque, se executam as seguintes etapas processuais: a) fixar a peça de metal em um dispositivo de aperto sob a formação de um local de recalque dentro da matriz, pelo que por fora do local de recalque, a peça esteja fixada de forma que as forças de recalque sejam captadas diretamente do ambiente circunjacente; b) aplicar um martelo de recalque sobre a peça de metal de modo que, quando sobre a peça se encontrar aplicada uma força, o material da peça de metal possa penetrar para o local de recalque; c) aplicar uma tensão de compressão prévia à peça de metal fixada pelo exercer de uma pressão sobre o martelo de recalque de forma que a tensão mecânica se encontre dentro da zona de elasticidade (de Hook); d) exercer um impulso por meio de um martelo de recalque sobre a peça de metal durante um período de tempo de duração tal e com uma força tal que o material da peça de metal passe da zona de elasticidade para a zona de fluência, pelo que o material possa se desviar dentro do local de recalque, o martelo de recalque possa se movimentar em avanço, pelo que a pressão sobre o material ceda e novamente possa retornar para a zona de elasticidade; e e) repetição periódica das etapas c) e d) até que o processo de recalque esteja concluído. Pelo método são obtidos produtos com uma estrutura homogênea.Invention Patent: "METHOD AND DEVICE FOR METAL TRANSFORMATION". In a method for working a metal part by means of repression in a repression device that contains a clamping device, a matrix and a repression hammer, the following procedural steps are performed: a) fix the metal part in a device tightening under the formation of a settlement location within the die, so that outside the settlement location, the part is fixed so that the settlement forces are captured directly from the surrounding environment; b) apply a repression hammer over the metal part so that, when a force is applied over the part, the material of the metal part can penetrate to the repression site; c) apply a previous compression tension to the metal part fixed by exerting pressure on the repression hammer so that the mechanical tension is within the elasticity zone (Hook); d) exert an impulse by means of a repressing hammer over the metal part for a period of time such that the material of the metal part passes from the elasticity area to the creep zone, so the material may deviate within the settlement point, the discharge hammer may move in advance, so that the pressure on the material relapses and again can return to the elasticity zone; and e) periodic repetition of steps c) and d) until the repression process is completed. By the method, products with a homogeneous structure are obtained.
