Abstract

resumo patente de invenção: "método para a produção de um pistão para um motor de combustão interna e pistão produzido pelo dito método". método para a produção de um pistão (10) para um motor de combustão interna, compreendendo uma parte superior do pistão (11) e uma parte inferior do pistão (18), onde a parte superior do pistão (11) tem um assoalho de pistão (12), um rebaixo de combustão (13) tendo uma cúpula (14), um espaço de queima circundante (15) e uma seção de anel circundante (16), onde a parte inferior do pistão (18) compreende bossas de êmbolo (19) providas com furos nas bossas (21), e as ditas bossas de êmbolo são conectadas umas às outras através das superfícies de escoamento (23, 24). o método compreende as seguintes etapas: a) produção do molde (11', 111', 211') da parte superior do pistão (11) por meio de um método de formação, b) produção do molde da parte inferior do pistão (18) por meio de um método de formação ou um método de fundição, c) conexão dos moldes da parte superior do pistão (11) e da parte inferior do pistão (18) por um método de soldagem para formar um corpo de pistão, d) usinagem secundária e/ou acabamento por usinagem do corpo de pistão para formar um pistão acabado (10). na etapa a), durante a produção do molde da parte superior do pistão (11), o contorno do rebaixo da combustão (13) afastado da região de cúpula (14', 114', 214') é acabado, e um material em excesso (25, 125, 225) é formado na região de cúpula (14', 114', 214') do rebaixo de combustão (13), e na etapa d), o material em excesso (25, 125, 225) na região de cúpula (14', 114', 214') do rebaixo de combustão (13) é removido em uma quantidade tal que resulta em um volume predeterminado da depressão de combustão (13).
