Abstract

"MéTODO DE FABRICAçãO DE UMA BROCA DE PERFURAçãO PARA PERFURAçãO DE ROCHA à PERCUSSãO E UMA BROCA DE PERFURAçãO DE ROCHA COM ELEMENTOS DE BOTãO". A presente invenção se refere a um método de fabricação de brocas de perfuração, para perfuração de rochas à percussão e a uma broca de perfuração de rocha (10) e um elemento de botão (14A). A broca de perfuração de rocha inclui uma porção de cabeça (11) com uma superfície avançada (13, 15), que apresenta um determinado número de elementos de botão (16), fornecidos em uma coroa periférica e um determinado número de elementos de botão frontais (14A -14F) posicionados internamente em relação aos elementos de botão periféricos (16). Pelo menos um dos ditos elementos de botão apresenta um diâmetro (D) e uma altura (H). O elemento de botão (14A) é soldado a uma parte essencialmente plana da superfície avançada. O elemento de botão é metalurgicamente ligado à superfície avançada (13 ,15) e em que se aplica a seguinte fórmula: H/D < 1,2.
