Abstract
Sposób bezwiórowego wykonywania otworów charakteryzuje się tym, że w pierwszej kolejności do powierzchni materiału (4), w strefie wykonania otworu, dosuwa się element ograniczający (3), mający korzystnie kształt tulei, po czym do miejsca wykonania otworu przybliża się wirujący trzpień (1) zamontowany obrotowo i przesuwnie względem segmentu kształtującego (2), mającego korzystnie postać pierścienia, a następnie wirujący trzpień (1) dociska się do powierzchni materiału (4) w miejscu wykonania otworu, przy czym wraz z dociskaniem trzpienia (1) do materiału (4), do strefy powstawania wypływki synchronicznie dosuwa się segment kształtujący (2).The method of cutting holes without holes is characterized by the fact that in the first place a stop element (3), preferably having the shape of a sleeve, moves towards the surface of the material (4), in the hole making area, then the rotating mandrel (1) approaches the hole mounted rotatably and slidingly relative to the shaping segment (2), preferably in the form of a ring, and then the rotating mandrel (1) is pressed against the surface of the material (4) at the location of the hole, with the pressure of the mandrel (1) against the material (4) , the shaping segment (2) is synchronously moved into the flash zone.
