Abstract

Narzędzie do walcowania gwintu z odcinkiem przyporu z kilkoma zębami profilowymi do wykonywania rowków gwintowych na zewnętrznej stronie obrabianego elementu o symetrii obrotowej, a zwłaszcza rury albo odcinka rurowego, charakteryzuje się tym, że pierwszy wchodzący w przypór w procesie walcowania ząb profilowy (14.1) jest wykonany całkowicie bez ewentualnie przewidzianej fazy, a osiowa rozciągłość (a) odcinka przyporu (12) odpowiada pojedynczemu skokowi krążka.A thread rolling tool with a buttress section with several profile teeth for producing thread grooves on the outside of a rotationally symmetrical workpiece, in particular a pipe or pipe section, characterized in that the first profile tooth (14.1) which engages in the buttress during the rolling process is made completely without any chamfer, if any, and the axial extension (a) of the buttress section (12) corresponds to a single stroke of the pulley.
