Abstract
"MéTODO DE FIXAçãO DE UM OU MAIS MEMBROS COM ORIFìCIO A UMA PEçA DE TRABALHO COM ORIFìCIO". Método de fixação de um ou mais membros com orifício a uma peça de trabalho com orifício, um orifício do, ou, de cada membro sendo alinhado com um orifício na peça de trabalho, cujo método compreende as etapas de inserir um fixador nos orifícios alinhados, o mencionado fixador sendo formado de material dúctil e tendo uma cabeça, um corpo, e um furo axial estendendo-se através do corpo e para a cabeça, o mencionado corpo sendo circunferencialmente inteiro e sendo formado com uma rosca de parafuso externa inserida, o mencionado fixador sendo inserido de modo que a cabeça encaixe uma face do mencionado um membro, e o corpo se estenda através do membro ou membros e para a peça de trabalho, e pelo menos uma parte da rosca de parafuso fique dentro da peça de trabalho e, depois, enquanto suportando o fixador na cabeça, puxar para, e, totalmente através do furo, na direção da porção posterior para a cabeça, uma cabeça de mandril afilada, maior, capaz de expandir o furo e, desse modo, aumentar o furo uniformemente por todo seu comprimento e causando expansão radial dúctil do corpo suficiente para causar a rosca de parafuso externa se incrustar na peça de trabalho e o corpo do fixador sofrendo redução axial dúctil no comprimento."METHOD OF FIXING ONE OR MORE MEMBERS WITH A HOLE TO A HOLE WORKPIECE". Method of securing one or more hole members to a hole workpiece, a hole in or of each member being aligned with a hole in the workpiece, which method comprises the steps of inserting a fastener into the aligned holes, said fastener being formed of ductile material and having a head, a body, and an axial hole extending through the body and to the head, said body being circumferentially integral and being formed with an inserted external screw thread, said fastener being inserted such that the head engages a face of said member, and the body extends through the member or members and into the workpiece, and at least a portion of the screw thread is within the workpiece and, then, while supporting the fastener to the head, pull toward, and through the hole fully, toward the rear portion to the head, a larger tapered mandrel head capable of expanding the shaft. thereby increasing the bore evenly over its entire length and causing sufficient ductile radial body expansion to cause the external screw thread to become embedded in the workpiece and the fastener body undergoing ductile axial reduction in length.
