Abstract

Dwustronny styczno-obrotowy nóż kombajnowy charakteryzuje się tym, że zawiera ostrze skrawające (2) w postaci dwóch jednakowych współosiowych brył obrotowych zbieżnych ku końcom i złączonych podstawami, osadzone w wybraniu czołowym (1a) trzonka (1) i zamocowane do trzonka (1) kształtowo za pośrednictwem oprawy (3) i pierścienia pośredniczącego (4) połączonych zgrzeiną (5). Sposób mocowania ostrzy w trzonkach noży polega na tym, że na ostrze skrawające (2) nakłada się oprawę (3), którą następnie łączy się z pierścieniem pośredniczącym (4) nałożonym uprzednio na część chwytową trzonka noża (1) zgrzeiną (5) tworzoną metodą elektro-iskrową za pomocą zgrzewarki oraz podłączonych do niej elektrod.The double-sided tangential-rotary combine knife is characterized by the fact that it includes a cutting blade (2) in the form of two identical coaxial rotary bodies converging towards the ends and joined by bases, embedded in the front recess (1a) of the shank (1) and fastened to the shank (1) positively through the housing (3) and the adapter ring (4) connected by a weld (5). The method of fixing the blades in the knife handles is based on the fact that a holder (3) is placed on the cutting blade (2), which is then connected to the adapter ring (4) previously placed on the handle part of the knife handle (1) with a weld (5) created by the method spark electrode by means of a welding machine and electrodes connected to it.
