Abstract

W przypadku układu do ustalania noża, w narzędziu wrębowym wrębiarki z oprawą noża i z obrotowo symetryczną tuleją noża ustalaną rozłącznie poprzez docisk powierzchniowy do osiowego ogranicznika ruchu w stożkowym elemencie ustalającym oprawy noża, przy czym tuleja noża ma długość osiową, przekraczającą długość osiową otworu dla tulei noża, w stanie ustalenia, część tulei (2) noża, wystająca ponad krawędź elementu ustalającego, na swym obwodzie zewnętrznym posiada stożkowe sfazowanie (10), pochylone w kierunku do wewnątrz.In the case of a knife retainer system, on a cutter notch tool with a knife holder and a rotationally symmetrical knife sleeve detachably retained by surface pressure against the axial travel stop in the conical knife holder retainer, the knife sleeve having an axial length exceeding the axial length of the hole for the knife sleeve in the steady state, the part of the knife sleeve (2) projecting above the edge of the retainer has a conical chamfer (10) on its outer periphery, inclined towards the inside.
