Abstract
<B>APERFEIçOAMENTO EM LâMINA DE CORTE UTILIZADA EM TEARES DE DESDOBRAMENTO DE BLOCOS DE PEDRA<D>, passível de ser aplicado em lâminas de corte usuais com feitio retangular (1) com espessura é reduzida, como também é geralmente fabricada de um material duro, tal como o aço e, apesar de ser uma peça de corte, tem a sua borda cortante (2) de maneira lisa, como se fosse uma longa régua, incluindo ainda adequada furação (3) para sua fixação ao cabeçote pendular do tear, onde geralmente são montadas várias lâminas, uma do lado da outra e de acordo com uma distância qualquer, compatível com a placa a ser cortada através de movimento pendular do conjunto de lâminas contra o bloco e em conjunto com um fluxo contínuo de abrasivo com abundância de água e, com isso, são provocados os desgastes extremos definidos pelos raios (R1) e cantos (C1), os quais são abrangidos ou circunscritos por conjuntos de ranhuras sucessivas (4), todas igualmente semi-elípticas, cujas extremidades (5) e (6) nascem e morrem na borda de corte (2) e, conseq³entemente, os seus trechos entre tais extremidades descrevem acentuado arqueamento para cima cujos raios aumentam gradualmente e proporcionalmente o suficiente para circunscrever os referidos desgastes (R1-C1) de cada operação completa de corte de um bloco, configurando áreas (A) removíveis, para preparação da lâmina para novo corte.<B> PERFECTING A CUTTING BLADE USED IN STONE BLOCK DEPLOYMENT TEARS <D>, which can be applied to usual cutting blades with a rectangular shape (1) with reduced thickness, as it is also generally made of a hard material , like steel and, despite being a cutting piece, has its cutting edge (2) smoothly, as if it were a long ruler, including a suitable hole (3) for fixing it to the pendulum head of the loom, where several blades are usually mounted, side by side and according to any distance, compatible with the plate to be cut through the pendulum movement of the blade set against the block and together with a continuous abrasive flow with plenty of extreme wear and tear defined by the spokes (R1) and corners (C1), which are covered or circumscribed by successive sets of grooves (4), all equally semi-elliptical, whose ends ages (5) and (6) are born and die at the cutting edge (2) and, consequently, their stretches between such ends describe a marked upward arch whose radii increase gradually and proportionally enough to circumscribe the referred wears (R1-C1 ) of each complete block cutting operation, configuring removable areas (A), to prepare the blade for a new cut.
