Abstract

PROCESSO DE FUNDIÇçO DE LATERAL DE UM TRUQUE, MODELO DE FUNDIÇçO, LATERAL DE UM TRUQUE DE VAGçO FERROVIÁRIO, TRUQUE DE VAGçO FERROVIÁRIO E VAGçO FERROVIÁRIO. A presente invenção refere-se a um processo de fundição de lateral de um truque ferroviário compreendendo as etapas de: (1) confecção do modelo (1); (ii) confecção do molde 2; (iii) confecção dos machos; (iv) colocação dos machos dos moldes; (v) vazamento de material fundido; e (vii) acabamento, sendo que os machos dos pedestais e da porção central da lateral do truque são suprimidos deste processo. A presente invenção também refere-se a um modelo de fundição (1), compreendendo uma primeira porção lateral (10) associada através de uma porção central (11) a uma segunda porção lateral (12). As porções laterais (10,12) são dotadas de um pedestal (30), com seu respectivo espaço (18), em suas extremidades livres e a porção central (11) é dotada de um espaço central (21). Os elementos formadores de cavidades colocados nos espaços de pedestal (18) e central (21) são suprimidos do modelo de fundição da presente invenção (1), de modo que os machos central e dos pedestais não possuem a necessidade de serem utilizados no processo de fundição, bem como o alojamento (23) para evitar a colocação do macho de curso de freio (9) no molde. Por fim, a presente invenção descreve, ainda, uma lateral de truque de vagão ferroviário cuja característica principal é o fato de ter sido produzida de acordo com o processo de fundição da presente invenção.SIDE FOOTWEAR PROCESS, FOUND MODEL, SIDE RAILWAY TRICK, RAILWAY TRUCK AND RAILWAY. The present invention relates to a side rail casting process comprising the steps of: (1) making the model (1); (ii) making the mold 2; (iii) male confection; (iv) placement of the mold males; (v) casting of molten material; and (vii) finishing, with the males of the pedestals and the central portion of the side of the trick being suppressed from this process. The present invention also relates to a casting model (1) comprising a first side portion (10) associated through a central portion (11) to a second side portion (12). The lateral portions (10,12) are provided with a pedestal (30), with its respective space (18), at its free ends and the central portion (11) is provided with a central space (21). The cavity forming elements placed in the pedestal (18) and central (21) spaces are deleted from the casting model of the present invention (1), so that the central and pedestal cores do not have to be used in the process of casting. as well as the housing (23) to prevent the placement of the brake stroke male (9) in the mold. Finally, the present invention further describes a railcar bogie side whose main feature is that it was produced in accordance with the casting process of the present invention.
