Abstract

Oppfinnelsen vedrører en fremgangsmåte for i det minste å hindre metallfretthet i et verktøy som er innfestet i en verktøyholder (4), hvilket verktøy har en frontside (6) utformet for bruk ved tilforming av metallfråd til stifter, skruer etc, og hvilken verktøyholder innbefatter en utsparing (6) utformet for opptak av verktøyet. Nye aspekter av fremgangsmåten innbefatter at verktøyet (2) har to sider (10,12) som danner en kileform som avsmalner mot verktøyets frontside (6), Idet vinkelen (A') til kileformen er mellom 0,5 og 45 grader, fortrinnsvis mellom I og 15 grader. Derved oppnås at verktøyet kan komprimeres mellom utsparingens sider, slik at kompresjonsspenninger introduseres i verktøyet. Som følge av vinkelen til verktøyets kileform og i utsparingen, kan kompresjonsspenningene nå et høyt nivå. Når verktøyet deretter benyttes for fremstilling av stifter/skruer, må de derved dannede strekkspenninger avlaste eller overvinne de innførte kompresjonsspenninger før en strekkspenningstilstand kan oppstå i verktøyet.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of at least preventing metal fatigue in a tool attached to a tool holder (4), which tool has a front side (6) designed for use in forming metal wires for pins, screws, etc., and which tool holder includes a tool holder. recess (6) designed for recording the tool. New aspects of the method include that the tool (2) has two sides (10,12) which form a wedge shape that tapers to the front side (6) of the tool, since the angle (A ') of the wedge shape is between 0.5 and 45 degrees, preferably between In and 15 degrees. This ensures that the tool can be compressed between the sides of the recess, so that compression stresses are introduced into the tool. Due to the angle of the tool wedge shape and in the recess, the compression stresses can reach a high level. When the tool is then used to make pins / screws, the resulting tensile stresses must relieve or overcome the introduced compression stresses before a tensile stress state can occur in the tool.
