Abstract

"reforçador inclinado e aparelho e método para moldar o mesmo". a presente invenção refere-se a um reforçador (24) que tem um elemento de alma alongado (30) e ao menos um elemento de pé alongado (28), com o elemento de alma e o elemento de pé conectados através de um cotovelo curvo, sendo que o raio do cotovelo curvo é maior sobre uma primeira parte (c) do reforçador do que sobre uma segunda parte (e) do reforçador. um molde de conformação de chapas por rolo (32) compreende um primeiro (34) e um segundo (36) cilindro, o primeiro cilindro tendo uma seção moldada disposta de modo a se localizar dentro de um correspondente recesso moldado na superfície de circunferência do segundo cilindro, o primeiro e o segundo cilindro definindo um espaço (40) entre eles que corresponde ao formato desejado a se transmitir sobre um componente alongado (20) passado entre os cilindros, com o formato desejado incluindo um cotovelo curvo entre uma alma e uma parte de pé, sendo que o formato do recesso no segundo cilindro e o formato da seção que corresponde à seção do primeiro cilindro variam em torno de uma parte da circunferência dos cilindros de modo que o raio de curvatura do espaço entre os cilindros que corresponde ao cotovelo curvo varia entre um valor mínimo e máximo. molda-se o reforçador alimentando-se um componente alongado através do molde de conformação de chapas por rolo e girando-se os cilindros de molde entre uma primeira e uma segunda posição quando se alimenta uma parte do componente alongado entre os cilindros de molde, através do que se varia o cotovelo curvo moldado no reforçador.
