Abstract

um artigo moldado por prensa da presente invenção tem uma placa de topo, paredes verticais e arestas entre as paredes verticais e a placa de topo, em que uma parte de mudança de formato existe em uma porção das arestas. um método de fabricação de artigo moldado por prensa da presente invenção compreende: uma etapa de preparação na qual uma placa metálica é preparada como uma matéria-prima; e uma etapa de processamento por prensa na qual a matéria-prima é submetida ao processamento por prensa com uso de uma punção, e um bloco e uma matriz que formam, cada um, um par com a punção. a etapa de processamento por prensa inclui: uma primeira etapa para moldar, com uso da punção e do bloco, a totalidade da placa de topo, a totalidade das arestas que inclui as partes de mudança de formato, e as regiões das paredes verticais que abrangem do limite entre as paredes verticais e as arestas até uma altura predeterminada; e uma segunda etapa, que segue a primeira etapa, para moldar as regiões remanescentes com uso da punção e da matriz em um estado em que a matéria-prima está sendo ensanduichada pela punção e o bloco.A press molded article of the present invention has a top plate, vertical walls and edges between the vertical walls and the top plate, wherein a shape change portion exists on a portion of the edges. A press molded article manufacturing method of the present invention comprises: a preparation step in which a metal plate is prepared as a raw material; and a press processing step in which the raw material is subjected to press processing using a punch, and a block and die each forming a pair with the punch. The press processing step includes: a first step for molding, using the punch and block, the entire top plate, the entire edge including the shape-shifting parts, and the vertical wall regions comprising from the boundary between the vertical walls and the edges to a predetermined height; and a second step, which follows the first step, to mold the remaining regions using the punch and die into a state where the raw material is being sandwiched by the punch and the block.
