Abstract

"MéTODO PARA A PRODUçãO DE UM PRODUTO SEMI-ACABADO PARA UM ELEMENTO EM FORMA DE ASA, E, ELEMENTO EM FORMA DE ASA". Um método para a produção de um produto semi-acabado (13) para um elemento em forma de asa (15) tendo, em seção transversal, uma borda dianteira (2), uma borda traseira (14) e uma parede de fundo arqueada (3) e uma parede de topo arqueada (4) que se estendem alguma distância separadamente entre a borda dianteira (2) e a borda traseira (14), inclui as etapas seguintes de: dobrar a folha (1) com a formação de dois painéis (3, 4) como também uma região curvada (2), em que os painéis (3, 4) se juntam, colocar um conformador (10) na folha dobrada (1) com a borda dianteira do conformador (9) posicionada na região curvada (2), forçar o membro de pressão (8) em direção a uma almofada de borracha (7) com a folha dobrada (1) encerrada entre eles e deformar dita folha entre o conformador (10) e a almofada de borracha (7), colocar a folha conformada (F) em uma prensa de borracha provida com um bloco de fundo tendo uma cavidade (16), que tem uma forma que corresponde pelo menos aproximadamente à forma externa de uma das paredes (3, 4) da folha conformada (P), pressionar a folha conformada (F) com o conformador (10) entre o bloco de fundo (11) e um tapete de borracha (12), remover o produto semi-acabado (13) da prensa de borracha."METHOD FOR PRODUCING A SEMI-FINISHED PRODUCT FOR A WING ELEMENT, AND, WING ELEMENT". A method for producing a semi-finished product (13) for a wing-shaped element (15) having, in cross-section, a front edge (2), a rear edge (14) and an arched bottom wall ( 3) and an arched top wall (4) extending some distance separately between the front edge (2) and the rear edge (14), includes the following steps of: folding the sheet (1) to form two panels (3, 4) as well as a curved region (2), in which the panels (3, 4) join, place a conformer (10) on the folded sheet (1) with the front edge of the conformer (9) positioned in the region. bent (2), force the pressure member (8) towards a rubber pad (7) with the folded sheet (1) enclosed therebetween and deform said sheet between the conformer (10) and the rubber pad (7 ), place the shaped sheet (F) in a rubber press provided with a bottom block having a cavity (16), which has a shape corresponding at least to near the outer shape of one of the walls (3, 4) of the shaped sheet (P), pressing the shaped sheet (F) with the conformer (10) between the bottom block (11) and a rubber mat (12), remove the semi-finished product (13) from the rubber press.
