Abstract

"MéTODO PARA PELO MENOS INIBIR A FADIGA DE METAL EM UMA FERRAMENTA FIXADA EM UM SUPORTE DE FERRAMENTA, SISTEMA DE FERRAMENTA, FERRAMENTA, E, USO DA MESMA". A presente invenção relaciona-se a um método para pelo menos inibir a fadiga de metal em uma ferramenta (2) fixada em um suporte de ferramenta (4), cuja ferramenta compreende um lado frontal (6) conformado para uso na formação de fio metálico em pregos, parafusos, etc., e cujo suporte de ferramenta compreende um rebaixo (8) adaptado para receber a ferramenta. Novos aspectos do método envolvem o fato da ferramenta (2) compreender dois lados (10, 12) formando uma forma de calço, que se estreita na direção do lado frontal (6) da ferramenta, onde o ângulo (A<39>) da forma de calço é entre 0,5 e 45 graus, e preferivelmente entre 1 e 15 graus. é deste modo obtido que a ferramenta pode ser comprimida entre os lados do rebaixo, de tal modo que tensões compressivas são introduzidos na ferramenta. Devido ao ângulo da forma de calço da ferramenta e do rebaixo, as tensões compressivas podem alcançar um alto nível. Quando o a ferramenta é usada posteriormente no processo de confecção de prego/parafuso, as tensões de tração causadas, precisam aliviar ou superar as tensões compressivas incorporadas, antes que um estado de tensão de tração na ferramenta possa estar presente."METHOD TO AT LEAST INHIBIT METAL FATIGUE IN A TOOL FIXED IN A TOOL HOLDER, TOOL SYSTEM, TOOL, AND, USE OF THE SAME". The present invention relates to a method of at least inhibiting metal fatigue in a tool (2) attached to a tool holder (4), the tool of which comprises a front side (6) shaped for use in forming wire. nails, screws, etc., and whose tool holder comprises a recess (8) adapted to receive the tool. New aspects of the method involve the fact that the tool (2) comprises two sides (10, 12) forming a shim shape, which narrows towards the front side (6) of the tool, where the angle (A <39>) of the tool Shim shape is between 0.5 and 45 degrees, and preferably between 1 and 15 degrees. It is thus obtained that the tool can be compressed between the sides of the recess such that compressive stresses are introduced into the tool. Due to the angle of the tool shim shape and the recess, the compressive stresses can reach a high level. When the tool is used later in the nail / screw making process, the tensile stresses caused must alleviate or overcome the compressive stresses incorporated before a tensile stress state in the tool can be present.
