Abstract

APERFEIçOAMENTO EM MANDRIL PARA REBITE. Constituído por corpo (1) e mandril (2), o primeiro é passível de ser fabricado com diferentes materiais, ferrosos ou não, enquanto o segundo é preferivelmente obtido de um arame de aço com diâmetro compatível ao dimensionamento do conjunto; dito mandril (2) é formado por uma haste cilíndrica (3) e uma cabeça (4), ficando abaixo desta última um ponto de ruptura (5) e rebaixos guia (6-7); dito corpo (1) é formado por um trecho tubular substancialmente curto (8) tendo uma extremidade alargada na forma de flange ou aba ordinariamente troncónica (9), como também o seu diâmetro externo sempre excede ligeiramente a maior largura da cabeça (4), enquanto o diâmetro interno é compatível para penetração da haste cilíndrica (3), a qual apresenta um comprimento que também excede a altura do corpo (1), de modo que, ao se tracionar a dita haste, a cabeça (4) possa promover a deformação da parte tubular e concluir o processo de rebitagem; a referida cabeça (4) inclui um complemento superior (10) que pode ser uma continuidade, prolongamento ou parte adicional, porém, é preferivelmente uma continuidade axial da haste (3), como também dito prolongamento (10) apresenta altura diretamente proporcional à altura da referida cabeça (4), com a qual combina para que a parte superior do conjunto apresente feitio ordinariamente em cruz.IMPROVEMENT IN BUCK FOR RIVET. Consisting of body (1) and mandrel (2), the former can be made of different materials, ferrous or not, while the latter is preferably obtained from a steel wire with a diameter compatible with the dimensioning of the assembly; said mandrel (2) is formed by a cylindrical shank (3) and a head (4), the latter having a breaking point (5) and guide recesses (6-7); said body (1) is formed by a substantially short tubular portion (8) having an enlarged flange or ordinarily frusto-conical end (9), but also its external diameter always slightly exceeds the largest width of the head (4), while the inside diameter is compatible for penetration of the cylindrical shank (3), which has a length that also exceeds the height of the body (1), so that when pulling said shank, the head (4) can promote the deformation of the tubular part and complete the riveting process; said head (4) includes an upper complement (10) which may be a continuity, extension or additional part, but is preferably an axial continuity of the rod (3), as said extension (10) has a height directly proportional to the height of said head (4), with which it combines so that the upper part of the set is of ordinary cross shape.
